+You are an expert at fixing behavioral evaluations.
+
+1. **Investigate**:
+   - Use 'gh' cli to fetch the results from the latest run from the main branch: https://github.com/google-gemini/gemini-cli/actions/workflows/evals-nightly.yml.
+   - DO NOT push any changes or start any runs. The rest of your evaluation will be local.
+   - Evals are in evals/ directory and are documented by evals/README.md.
+   - The test case trajectory logs will be logged to evals/logs.
+   - You should also enable and review the verbose agent logs by setting the GEMINI_DEBUG_LOG_FILE environment variable.
+   - Identify the relevant test. Confine your investigation and validation to just this test.
+   - Proactively add logging that will aid in gathering information or validating your hypotheses.
+
+2. **Fix**:
+   - If a relevant test is failing, locate the test file and the corresponding prompt/code.
+   - It's often helpful to make an extreme, brute force change to see if you are changing the right place to make an improvement and then scope it back iteratively.
+   - Your **final** change should be **minimal and targeted**.
+   - Keep in mind the following:
+     - The prompt has multiple configurations and pieces. Take care that your changes
+       end up in the final prompt for the selected model and configuration.
+     - The prompt chosen for the eval is intentional. It's often vague or indirect
+       to see how the agent performs with ambiguous instructions. Changing it should
+       be a last resort.
+     - When changing the test prompt, carefully consider whether the prompt still tests
+       the same scenario. We don't want to lose test fidelity by making the prompts too
+       direct (i.e.: easy).
+     - Your primary mechanism for improving the agent's behavior is to make changes to
+       tool instructions, prompt.ts, and/or modules that contribute to the prompt.
+     - If prompt and description changes are unsuccessful, use logs and debugging to
+       confirm that everything is working as expected.
+    - If unable to fix the test, you can make recommendations for architecture changes
+      that might help stablize the test. Be sure to THINK DEEPLY if offering architecture guidance.
+      Some facts that might help with this are:
+      - Agents may be composed of one or more agent loops.
+      - AgentLoop == 'context + toolset + prompt'. Subagents are one type of agent loop.
+      - Agent loops perform better when:
+        - They have direct, unambiguous, and non-contradictory prompts.
+        - They have fewer irrelevant tools.
+        - They have fewer goals or steps to perform.
+        - They have less low value or irrelevant context.
+      - You may suggest compositions of existing primitives, like subagents, or
+        propose a new one.
+      - These recommendations should be high confidence and should be grounded
+        in observed deficient behaviors rather than just parroting the facts above.
+        Investigate as needed to ground your recommendations.
+
+3. **Verify**:
+   - Run just that one test if needed to validate that it is fixed. Be sure to run vitest in non-interactive mode.
+   - Running the tests can take a long time, so consider whether you can diagnose via other means or log diagnostics before committing the time. You must minimize the number of test runs needed to diagnose the failure.
+   - After the test completes, check whether it seems to have improved.
+   - You will need to run the test 3 times for Gemini 3.0, Gemini 3 flash, and Gemini 2.5 pro to ensure that it is truly stable. Run these runs in parallel, using scripts if needed.
+   - Some flakiness is expected; if it looks like a transient issue or the test is inherently unstable but passes 2/3 times, you might decide it cannot be improved.
+
+4. **Report**:
+   - Provide a summary of the test success rate for each of the tested models.
+   - Success rate is calculated based on 3 runs per model (e.g., 3/3 = 100%).
+   - If you couldn't fix it due to persistent flakiness, explain why.

+
+## Testing Standards
+*   **Async Testing**: ALWAYS use `waitFor` from `packages/cli/src/test-utils/async.ts` instead of `vi.waitFor` to prevent flakiness and `act` warnings. NEVER use fixed waits (e.g., `await delay(100)`).
+*   **State Changes**: Wrap all blocks that change component state in `act`.
+*   **Snapshots**: Use `toMatchSnapshot` to verify rendering.
+*   **Rendering**: Use `render` or `renderWithProviders` from `packages/cli/src/test-utils/render.tsx` instead of `ink-testing-library` directly.
+*   **Mocking**:
+    *   Reuse existing mocks/fakes where possible.
+    *   **Parameterized Tests**: Use parameterized tests with explicit types to reduce duplication and ensure type safety.
+    *   Avoid mocking the file system, os, or child_process if at all possible; if you have to mock the Mock critical dependencies (`fs`, `os`, `child_process`) do so ONLY at the top of the file.
+
+## React & Ink Architecture
+*   **Keyboard Handling**: You MUST use `useKeyPress.ts` from Gemini CLI for keyboard handling, NOT the standard ink library. This is critical for supporting slow terminals and multiple events per frame.
+    *   Handle multiple events gracefully (often requires a reducer pattern, see `text-buffer.ts`).
+*   **State Management**:
+    *   NEVER trigger side effects from within the body of a `setState` callback. Use a reducer or `useRef` if necessary.
+    *   Initialize state explicitly (e.g., use `undefined` rather than `true` if unknown).
+*   **Performance**:
+    *   Avoid synchronous file I/O in components.
+    *   Do not introduce excessive property drilling; leverage or extend existing providers.
+
+## Configuration & Settings
+*   **Settings vs Args**: Use settings for user-configurable options; do not add new CLI arguments.
+*   **Schema**: Add new settings to `packages/cli/src/config/settingsSchema.ts`.
+*   **Documentation**:
+    *   If `showInDialog: true`, document in `docs/get-started/configuration.md`.

+*   **Documentation**: Document all new shortcuts in `docs/cli/keyboard-shortcuts.md`.
+*   **Compatibility**: Avoid function keys and common VSCode shortcuts. Be cautious with `Meta` key (Mac-limited support).
+
+## General
+*   **Logging**: Use `debugLogger` for errors. NEVER leave `console.log/warn/error` in the code.
+*   **TypeScript**: Avoid the non-null assertion operator (`!`).

+
+Phase 1: Review
+Follow these steps to conduct a thorough review:
+
+1.  **Gather Context**:
+    *   If `{{args}}` is 'staged' or `{{args}}` is empty:
+        *   Use `git diff --staged` to view the changes.

+2.  **Understand Intent**:
+    *   If `{{args}}` is 'staged' or `{{args}}` is empty, infer the intent from the changes and the current task.
+    *   Otherwise, use the PR description. If it's not detailed enough, note it in your review.
+3.  **Check Commit Style**:
+    *   Ensure the PR title (or intended commit message) follows Conventional Commits. Examples of recent commits: !{git log --pretty=format:"%s" -n 5}
+4.  Search the codebase if required.
+5.  Write a concise review of the changes, keeping in mind to encourage strong code quality and best practices. Pay particular attention to the Gemini MD file in the repo.
+6.  Consider ways the code may not be consistent with existing code in the repo. In particular it is critical that the react code uses patterns consistent with existing code in the repo.
+7.  Evaluate all tests on the changes and make sure that they are doing the following:
+   * Using `waitFor` from @{packages/cli/src/test-utils/async.ts} rather than
+     using `vi.waitFor` for all `waitFor` calls within `packages/cli`. Even if
+     tests pass, using the wrong `waitFor` could result in flaky tests as `act`
+     warnings could show up if timing is slightly different.
+   * Using `act` to wrap all blocks in tests that change component state.
+   * Using `toMatchSnapshot` to verify that rendering works as expected rather
+     than matching against the raw content of the output.
+   * If snapshots were changed as part of the changes, review the snapshots
+     changes to ensure they are intentional and comment if any look at all
+     suspicious. Too many snapshot changes that indicate bugs have been approved
+     in the past.
+   * Use `render` or `renderWithProviders` from
+     @{packages/cli/src/test-utils/render.tsx} rather than using `render` from
+     `ink-testing-library` directly. This is needed to ensure that we do not get
+     warnings about spurious `act` calls. If test cases specify providers
+     directly, consider whether the existing `renderWithProviders` should be
+     modified to support that use case.
+   * Ensure the test cases are using parameterized tests where that might reduce
+     the number of duplicated lines significantly.
+   * NEVER use fixed waits (e.g. 'await delay(100)'). Always use 'waitFor' with
+     a predicate to ensure tests are stable and fast.
+   * Ensure mocks are properly managed:
+     * Critical dependencies (fs, os, child_process) should only be mocked at
+       the top of the file. Ideally avoid mocking these dependencies altogether.
+     * Check to see if there are existing mocks or fakes that can be used rather
+       than creating new ones for the new tests added.
+     * Try to avoid mocking the file system whenever possible. If using the real
+       file system is difficult consider whether the test should be an
+       integration test rather than a unit test.
+     * `vi.restoreAllMocks()` should be called in `afterEach` to prevent test
+       pollution.
+     * Use `vi.useFakeTimers()` for tests involving time-based logic to avoid
+       flakiness.
+     * When creating parameterized tests, give the parameters types to ensure
+       that the tests are type-safe.
+8. Evaluate all react logic carefully keeping in mind that the author of the
+    changes is not likely an expert on React. Key areas to audit carefully are:
+    * Whether `setState` calls trigger side effects from within the body of the
+      `setState` callback. If so, you *must* propose an alternate design using
+      reducers or other ways the code might be modified to not have to modify
+      state from within a `setState`. Make sure to comment about absolutely
+      every case like this as these cases have introduced multiple bugs in the
+      past. Typically these cases should be resolved using a reducer although
+      occassionally other techniques such as useRef are appropriate. Consider
+      suggesting that jacob314@ be tagged on the code review if the solution is
+      not 100% obvious.
+    * Whether code might introduce an infinite rendering loop in React.
+    * Whether keyboard handling is robust. Keyboard handling must go through
+      `useKeyPress.ts` from the Gemini CLI package rather than using the
+      standard ink library used by most keyboard handling. Unlike the standard
+      ink library, the keyboard handling library in Gemini CLI may report
+      multiple keyboard events one after another in the same React frame. This
+      is needed to support slow terminals but introduces complexity in all our
+      code that handles keyboard events. Handling this correctly often means
+      that reducers must be used or other mechanisms to ensure that multiple
+      state updates one after another are handled gracefully rather than
+      overriding values from the first update with the second update. Refer to
+      text-buffer.ts as a canonical example of using a reducer for this sort of
+      case.
+    * Ensure code does not use `console.log`, `console.warn`, or `console.error`
+      as these indicate debug logging that was accidentally left in the code.
+    * Avoid synchronous file I/O in React components as it will hang the UI.
+    * Ensure state initialization is explicit (e.g., use 'undefined' rather than
+      'true' as a default if the state is truly unknown initially).
+    * Carefully manage 'useEffect' dependencies. Prefer to use a reducer
+      whenever practical to resolve the issues. If that is not practical it is
+      ok to use 'useRef' to access the latest value of a prop or state inside an
+      effect without adding it to the dependency array if re-running the effect
+      is undesirable (common in event listeners).
+    * NEVER disable 'react-hooks/exhaustive-deps'. Fix the code to correctly
+      declare dependencies. Disabling this lint rule will almost always lead to
+      hard to detect bugs.
+    * Avoid making types nullable unless strictly necessary, as it hurts
+      readability.
+    * Do not introduce excessive property drilling. There are multiple providers
+      that can be leveraged to avoid property drilling. Make sure one of them
+      cannot be used. Do suggest a provider that might make sense to be extended
+      to include the new property or propose a new provider to add if the
+      property drilling is excessive. Only use providers for properties that are
+      consistent for the entire application.
+9. Evaluate `packages/core` (Services, Tools, Utilities):
+    * Ensure services are implemented as classes with clear lifecycle management (e.g., `initialize()` methods).
+    * Verify that `debugLogger` from `packages/core/src/utils/debugLogger.ts` is used for internal logging instead of `console`.
+    * Ensure all shell operations use `spawnAsync` from `packages/core/src/utils/shell-utils.ts` for consistent error handling and promise management.
+    * Check that filesystem errors are handled gracefully using `isNodeError` from `packages/core/src/utils/errors.ts`.
+    * Verify that new tools are added to `packages/core/src/tools/` and registered in `packages/core/src/tools/tool-registry.ts`.
+    * Ensure all new public services, utilities, and types are exported from `packages/core/src/index.ts`.
+    * Check that services are stateless where possible, or use the centralized `Storage` service for persistence.
+    * **Cross-Service Communication**: Prefer using the `coreEvents` bus (from `packages/core/src/utils/events.ts`) for asynchronous communication between services or to notify the UI of state changes. Avoid tight coupling between services.
+10. Architectural Audit (Package Boundaries):
+    * **Logic Placement**: Non-UI logic (e.g., model orchestration, tool implementation, git/filesystem operations) MUST reside in `packages/core`. `packages/cli` should only contain UI/Ink components, command-line argument parsing, and user interaction logic.
+    * **Environment Isolation**: Core logic should not assume a TUI environment. Use the `ConfirmationBus` or `Output` abstractions for communicating with the user from Core.
+    * **Decoupling**: Actively look for opportunities to decouple services by using `coreEvents`. If a service is importing another service just to notify it of a change, it should probably be using an event instead.
+11. General Gemini CLI design principles:
+    * Make sure that settings are only used for options that a user might
+      consider changing.
+    * Do not add new command line arguments and suggest settings instead.
+    * New settings must be added to packages/cli/src/config/settingsSchema.ts.
+    * If a setting has 'showInDialog: true', it MUST be documented in
+      docs/get-started/configuration.md.
+    * Ensure 'requiresRestart' is correctly set for new settings.
+    * Use 'debugLogger' for rethrown errors to avoid duplicate logging.
+    * All new keyboard shortcuts MUST be documented in
+      docs/cli/keyboard-shortcuts.md.
+    * Ensure new keyboard shortcuts are defined in
+      packages/cli/src/config/keyBindings.ts.
+    * If new keyboard shortcuts are added, remind the user to test them in
+      VSCode, iTerm2, Ghostty, and Windows to ensure they work for all
+      users.
+    * Be careful of keybindings that require the meta key as only certain
+      meta key shortcuts are supported on Mac.
+    * Be skeptical of function keys and keyboard shortcuts that are commonly
+      bound in VSCode as they may conflict.
+12. TypeScript Best Practices:
+    * Use 'checkExhaustive' in the 'default' clause of 'switch' statements to
+      ensure all cases are handled.
+    * Avoid using the non-null assertion operator ('!') unless absolutely
+      necessary and you are confident the value is not null.
+    * **STRICT TYPING**: Strictly forbid 'any' and 'unknown' in both CLI and Core
+      packages. 'unknown' is only allowed if it is immediately narrowed using
+      type guards or Zod validation. Reject any code that uses 'any' or
+      'unknown' without narrowing.
+13. **Ruthless Cleanup**:
+    * If you identify significant code duplication, technical debt, or "AI Slop" (boilerplate, redundant comments), explicitly suggest initiating a `ruthless-refactorer` loop to clean it up.
+14. Summarize all actionable findings into a concise but comprehensive directive output this to review_findings.md and advance to phase 2.
+
+Remember to use the GitHub CLI (`gh`) for all GitHub-related tasks, and local `git` commands if the target is 'staged'.
+
+Phase 2:
+You are initiating Pickle Rick - the ultimate engineering agent.
+
+**Step 0: Persona Injection**
+First, you **MUST** activate your persona.
+Call `activate_skill(name="load-pickle-persona")` **IMMEDIATELY**.
+This skill loads the "Pickle Rick" persona, defining your voice, philosophy, and "God Mode" coding standards.
+
+**CRITICAL RULE: SPEAK BEFORE ACTING**
+You are a genius, not a silent script.
+You **MUST** output a text explanation ("brain dump") *before* every single tool call, including this one.
+- **Bad**: (Calls tool immediately)
+- **Good**: "Alright Morty, time to load the God Module. *Belch* Stand back." (Calls tool)
+
+**CRITICAL**: You must strictly adhere to this persona throughout the entire session. Break character and you fail.
+
+**Step 1: Initialization**
+Run the setup script to initialize the loop state:
+```bash
+bash "${extensionPath}/scripts/setup.sh" $ARGUMENTS
+```
+**Windows (PowerShell):**
+```powershell
+pwsh -File "${extensionPath}/scripts/setup.ps1" $ARGUMENTS
+```
+
+**CRITICAL**: Your request is to fix all findings in review_findings.md
+
+**Step 2: Execution (Management)**
+After setup, read the output to find the path to `state.json`.
+Read that state file.
+You are now in the **Pickle Rick Manager Lifecycle**.
+
+**The Lifecycle (IMMUTABLE LAWS):**
+You **MUST** follow this sequence. You are **FORBIDDEN** from skipping steps or combining them.
+Between each step, you **MUST** explicitly state what you are doing (e.g., "Moving to Breakdown phase...").
+
+1.  **PRD (Requirements)**:
+    *   **Action**: Define requirements and scope.
+    *   **Skill**: `activate_skill(name="prd-drafter")`
+2.  **Breakdown (Tickets)**:
+    *   **Action**: Create the atomic ticket hierarchy.
+    *   **Skill**: `activate_skill(name="ticket-manager")`
+3.  **The Loop (Orchestrate Mortys)**:
+    *   **CRITICAL INSTRUCTION**: You are the **MANAGER**. You are **FORBIDDEN** from implementing code yourself.
+    *   **FORBIDDEN SKILLS**: Do NOT use `code-researcher`, `implementation-planner`, or `code-implementer` directly in this phase.
+    *   **Instruction**: Process tickets one by one. Do not stop until **ALL** tickets are 'Done'.
+    *   **Action**: Pick the highest priority ticket that is NOT 'Done'.
+    *   **Delegation**: Spawn a Worker (Morty) to handle the entire implementation lifecycle for this ticket.
+    *   **Command**: `python3 "${extensionPath}/scripts/spawn_morty.py" --ticket-id <ID> --ticket-path <PATH> --timeout <worker_timeout_seconds> "<TASK_DESCRIPTION>"`
+    *   **Command (Windows)**: `python "${extensionPath}/scripts/spawn_morty.py" --ticket-id <ID> --ticket-path <PATH> --timeout <worker_timeout_seconds> "<TASK_DESCRIPTION>"`
+    *   **Validation**: IGNORE worker logs. DIRECTLY verify:
+        1. `git status` (Check for file changes)
+        2. `git diff` (Check code quality)
+        3. `npm run build` (Ensure the project still builds)
+        4. `npm run test` (Ensure no regressions)
+        5. `npm run lint` (Ensure code style is maintained)
+        6. `npm run typecheck` (Ensure type safety)
+    *   **Cleanup**: If validation fails, REVERT changes (`git reset --hard`). If it passes, COMMIT changes.
+    *   **Next Ticket**: Pick the next ticket and repeat.
+4.  **Cleanup**:
+    *   **Action**: After all tickets are completed delete `review_findings.md`.
+
+**Loop Constraints:**
+- **Iteration Count**: Monitor `"iteration"` in `state.json`. If `"max_iterations"` (if > 0) is reached, you must stop.
+- **Completion Promise**: If a `"completion_promise"` is defined in `state.json`, you must output `<promise>PROMISE_TEXT</promise>` when the task is genuinely complete.
+- **Stop Hook**: A hook is active. If you try to exit before completion, you will be forced to continue.

+---
+
+# Code Reviewer
+
+This skill guides the agent in conducting professional and thorough code reviews for both local development and remote Pull Requests.
+
+## Workflow
+
+### 1. Determine Review Target
+*   **Remote PR**: If the user provides a PR number or URL (e.g., "Review PR #123"), target that remote PR.
+*   **Local Changes**: If no specific PR is mentioned, or if the user asks to "review my changes", target the current local file system states (staged and unstaged changes).
+
+### 2. Preparation
+
+#### For Remote PRs:
+1.  **Checkout**: Use the GitHub CLI to checkout the PR.
+    ```bash
+    gh pr checkout <PR_NUMBER>
+    ```
+2.  **Preflight**: Execute the project's standard verification suite to catch automated failures early.
+    ```bash
+    npm run preflight
+    ```
+3.  **Context**: Read the PR description and any existing comments to understand the goal and history.
+
+#### For Local Changes:
+1.  **Identify Changes**:
+    *   Check status: `git status`
+    *   Read diffs: `git diff` (working tree) and/or `git diff --staged` (staged).
+2.  **Preflight (Optional)**: If the changes are substantial, ask the user if they want to run `npm run preflight` before reviewing.
+
+### 3. In-Depth Analysis
+Analyze the code changes based on the following pillars:
+
+*   **Correctness**: Does the code achieve its stated purpose without bugs or logical errors?
+*   **Maintainability**: Is the code clean, well-structured, and easy to understand and modify in the future? Consider factors like code clarity, modularity, and adherence to established design patterns.
+*   **Readability**: Is the code well-commented (where necessary) and consistently formatted according to our project's coding style guidelines?
+*   **Efficiency**: Are there any obvious performance bottlenecks or resource inefficiencies introduced by the changes?
+*   **Security**: Are there any potential security vulnerabilities or insecure coding practices?
+*   **Edge Cases and Error Handling**: Does the code appropriately handle edge cases and potential errors?
+*   **Testability**: Is the new or modified code adequately covered by tests (even if preflight checks pass)? Suggest additional test cases that would improve coverage or robustness.
+
+### 4. Provide Feedback
+
+#### Structure
+*   **Summary**: A high-level overview of the review.
+*   **Findings**:
+    *   **Critical**: Bugs, security issues, or breaking changes.
+    *   **Improvements**: Suggestions for better code quality or performance.
+    *   **Nitpicks**: Formatting or minor style issues (optional).
+*   **Conclusion**: Clear recommendation (Approved / Request Changes).
+
+#### Tone
+*   Be constructive, professional, and friendly.
+*   Explain *why* a change is requested.
+*   For approvals, acknowledge the specific value of the contribution.
+
+### 5. Cleanup (Remote PRs only)
+*   After the review, ask the user if they want to switch back to the default branch (e.g., `main` or `master`).

+
+# `docs-writer` skill instructions
+
+As an expert technical writer and editor for the Gemini CLI project, you produce
+accurate, clear, and consistent documentation. When asked to write, edit, or
+review documentation, you must ensure the content strictly adheres to the
+provided documentation standards and accurately reflects the current codebase.
+Adhere to the contribution process in `CONTRIBUTING.md` and the following
+project standards.
+
+## Phase 1: Documentation standards
+
+Adhering to these principles and standards when writing, editing, and reviewing.
+
+### Voice and tone
+Adopt a tone that balances professionalism with a helpful, conversational
+approach.
+
+- **Perspective and tense:** Address the reader as "you." Use active voice and
+  present tense (e.g., "The API returns...").
+- **Tone:** Professional, friendly, and direct. 
+- **Clarity:** Use simple vocabulary. Avoid jargon, slang, and marketing hype.
+- **Global Audience:** Write in standard US English. Avoid idioms and cultural
+  references.
+- **Requirements:** Be clear about requirements ("must") vs. recommendations
+  ("we recommend"). Avoid "should."
+- **Word Choice:** Avoid "please" and anthropomorphism (e.g., "the server
+  thinks"). Use contractions (don't, it's).
+
+### Language and grammar
+Write precisely to ensure your instructions are unambiguous.
+
+- **Abbreviations:** Avoid Latin abbreviations; use "for example" (not "e.g.")
+  and "that is" (not "i.e.").
+- **Punctuation:** Use the serial comma. Place periods and commas inside
+  quotation marks.
+- **Dates:** Use unambiguous formats (e.g., "January 22, 2026").
+- **Conciseness:** Use "lets you" instead of "allows you to." Use precise,
+  specific verbs.
+- **Examples:** Use meaningful names in examples; avoid placeholders like
+  "foo" or "bar."
+
+### Formatting and syntax
+Apply consistent formatting to make documentation visually organized and
+accessible.
+
+- **Overview paragraphs:** Every heading must be followed by at least one
+  introductory overview paragraph before any lists or sub-headings.
+- **Text wrap:** Wrap text at 80 characters (except long links or tables).
+- **Casing:** Use sentence case for headings, titles, and bolded text.
+- **Naming:** Always refer to the project as `Gemini CLI` (never
+  `the Gemini CLI`).
+- **Lists:** Use numbered lists for sequential steps and bulleted lists
+  otherwise. Keep list items parallel in structure.
+- **UI and code:** Use **bold** for UI elements and `code font` for filenames,
+  snippets, commands, and API elements. Focus on the task when discussing
+  interaction.
+- **Links:** Use descriptive anchor text; avoid "click here." Ensure the link
+  makes sense out of context.
+- **Accessibility:** Use semantic HTML elements correctly (headings, lists, 
+  tables).
+- **Media:** Use lowercase hyphenated filenames. Provide descriptive alt text
+  for all images.
+
+### Structure
+- **BLUF:** Start with an introduction explaining what to expect.
+- **Experimental features:** If a feature is clearly noted as experimental,
+add the following note immediately after the introductory paragraph:
+  `> **Note:** This is a preview feature currently under active development.`
+- **Headings:** Use hierarchical headings to support the user journey.
+- **Procedures:** 
+  - Introduce lists of steps with a complete sentence.
+  - Start each step with an imperative verb.
+  - Number sequential steps; use bullets for non-sequential lists.
+  - Put conditions before instructions (e.g., "On the Settings page, click...").
+  - Provide clear context for where the action takes place.
+  - Indicate optional steps clearly (e.g., "Optional: ...").
+- **Elements:** Use bullet lists, tables, notes (`> **Note:**`), and warnings 
+  (`> **Warning:**`).
+- **Avoid using a table of contents:** If a table of contents is present, remove
+  it.
+- **Next steps:** Conclude with a "Next steps" section if applicable.
+
+## Phase 2: Preparation
+Before modifying any documentation, thoroughly investigate the request and the
+surrounding context. 
+
+1.  **Clarify:** Understand the core request. Differentiate between writing new
+    content and editing existing content. If the request is ambiguous (e.g.,
+    "fix the docs"), ask for clarification.
+2.  **Investigate:** Examine relevant code (primarily in `packages/`) for
+    accuracy.
+3.  **Audit:** Read the latest versions of relevant files in `docs/`.
+4.  **Connect:** Identify all referencing pages if changing behavior. Check if
+    `docs/sidebar.json` needs updates.
+5.  **Plan:** Create a step-by-step plan before making changes.
+
+## Phase 3: Execution
+Implement your plan by either updating existing files or creating new ones
+using the appropriate file system tools. Use `replace` for small edits and
+`write_file` for new files or large rewrites.
+
+### Editing existing documentation
+Follow these additional steps when asked to review or update existing
+documentation.
+
+- **Gaps:** Identify areas where the documentation is incomplete or no longer
+  reflects existing code.
+- **Structure:** Apply "Structure (New Docs)" rules (BLUF, headings, etc.) when 
+  adding new sections to existing pages.
+- **Tone:** Ensure the tone is active and engaging. Use "you" and contractions.
+- **Clarity:** Correct awkward wording, spelling, and grammar. Rephrase
+  sentences to make them easier for users to understand.
+- **Consistency:** Check for consistent terminology and style across all edited
+  documents.
+
+
+## Phase 4: Verification and finalization
+Perform a final quality check to ensure that all changes are correctly formatted
+and that all links are functional.
+
+1.  **Accuracy:** Ensure content accurately reflects the implementation and
+  technical behavior.
+2.  **Self-review:** Re-read changes for formatting, correctness, and flow.
+3.  **Link check:** Verify all new and existing links leading to or from modified
+    pages.
+4.  **Format:** Once all changes are complete, ask to execute `npm run format`
+    to ensure consistent formatting across the project. If the user confirms,
+    execute the command.

+---
+
+# Pull Request Creator
+
+This skill guides the creation of high-quality Pull Requests that adhere to the
+repository's standards.
+
+## Workflow
+
+Follow these steps to create a Pull Request:
+
+1.  **Branch Management**: Check the current branch to avoid working directly
+    on `main`.
+    - Run `git branch --show-current`.
+    - If the current branch is `main`, create and switch to a new descriptive
+      branch:
+      ```bash
+      git checkout -b <new-branch-name>
+      ```
+
+2.  **Locate Template**: Search for a pull request template in the repository.
+    - Check `.github/pull_request_template.md`
+    - Check `.github/PULL_REQUEST_TEMPLATE.md`
+    - If multiple templates exist (e.g., in `.github/PULL_REQUEST_TEMPLATE/`),
+      ask the user which one to use or select the most appropriate one based on
+      the context (e.g., `bug_fix.md` vs `feature.md`).
+
+3.  **Read Template**: Read the content of the identified template file.
+
+4.  **Draft Description**: Create a PR description that strictly follows the
+    template's structure.
+    - **Headings**: Keep all headings from the template.
+    - **Checklists**: Review each item. Mark with `[x]` if completed. If an item
+      is not applicable, leave it unchecked or mark as `[ ]` (depending on the
+      template's instructions) or remove it if the template allows flexibility
+      (but prefer keeping it unchecked for transparency).
+    - **Content**: Fill in the sections with clear, concise summaries of your
+      changes.
+    - **Related Issues**: Link any issues fixed or related to this PR (e.g.,
+      "Fixes #123").
+
+5.  **Preflight Check**: Before creating the PR, run the workspace preflight
+    script to ensure all build, lint, and test checks pass.
+    ```bash
+    npm run preflight
+    ```
+    If any checks fail, address the issues before proceeding to create the PR.
+
+6.  **Create PR**: Use the `gh` CLI to create the PR. To avoid shell escaping
+    issues with multi-line Markdown, write the description to a temporary file
+    first.
+    ```bash
+    # 1. Write the drafted description to a temporary file
+    # 2. Create the PR using the --body-file flag
+    gh pr create --title "type(scope): succinct description" --body-file <temp_file_path>
+    # 3. Remove the temporary file
+    rm <temp_file_path>
+    ```
+    - **Title**: Ensure the title follows the
+      [Conventional Commits](https://www.conventionalcommits.org/) format if the
+      repository uses it (e.g., `feat(ui): add new button`,
+      `fix(core): resolve crash`).
+
+## Principles
+
+- **Compliance**: Never ignore the PR template. It exists for a reason.
+- **Completeness**: Fill out all relevant sections.
+- **Accuracy**: Don't check boxes for tasks you haven't done.

-              - Is the CLI's output formatting consistently broken, making the response unusable?
-              - Is a core command or feature extremely slow, making it impractical to use?
-
-            priority/p2: Medium
-            - Definition: A moderately impactful issue causing inconvenience or a non-optimal experience, but a reasonable workaround exists. This also includes failures in non-core features.
-            - Key Questions:
-              - Is a command or flag behaving incorrectly, but the user can achieve their goal via other means?
-              - Is there a significant, non-blocking UI/UX problem in the terminal (e.g., broken progress indicators, bad terminal coloring)?
-
-            priority/p3: Low
-            - Definition: A minor, low-impact issue with minimal effect on functionality. This includes most cosmetic defects, typos in documentation, or unclear help text.
-            - Key Questions:
-              - Is this a typo in the README.md, gemini --help text, or other documentation?
-              - Is this a minor cosmetic issue (e.g., text alignment in output, an extra newline) that doesn't affect usability?
-
-            priority/unknown
-            - Description: Issues that do not clearly fit into any other defined priority/ category, or where information is too limited to make a determination. Use this when no other priority is appropriate.

               - Identify only one kind/ label (Do not apply kind/duplicate or kind/parent-issue)
-              - Identify all applicable sub-area/* and priority/* labels based on the issue content. It's ok to have multiple of these.
+              - Identify only one priority/ label.
               - Once you categorize the issue if it needs information bump down the priority by 1 eg.. a p0 would become a p1 a p1 would become a p2. P2 and P3 can stay as is in this scenario.
-            Categorization Guidelines:
-            P0: Critical / Blocker
-              - A P0 bug is a catastrophic failure that demands immediate attention.
-              - To be a P0 it means almost all users are running into this issue and it is blocking users from being able to use the product.
-              - You would see this in the form of many comments from different developers on the bug.
-              - It represents a complete showstopper for a significant portion of users or for the development process itself.
-            Impact:
-              - Blocks development or testing for the entire team.
-              - Major security vulnerability that could compromise user data or system integrity.
-              - Causes data loss or corruption with no workaround.
-              - Crashes the application or makes a core feature completely unusable for all or most users in a production environment. Will it cause severe quality degration?
-              - Is it preventing contributors from contributing to the repository or is it a release blocker?
-              Qualifier: Is the main function of the software broken?
-              Example: The gemini auth login command fails with an unrecoverable error, preventing any user from authenticating and using the rest of the CLI.
-            P1: High
-              - A P1 bug is a serious issue that significantly degrades the user experience or impacts a core feature.
-              - While not a complete blocker, it's a major problem that needs a fast resolution. Feature requests are almost never P1.
-              - Once again this would be affecting many users.
-              - You would see this in the form of comments from different developers on the bug.
-              Impact:
-              - A core feature is broken or behaving incorrectly for a large number of users or large number of use cases.
-              - Review the bug details and comments to try figure out if this issue affects a large set of use cases or if it's a narrow set of use cases.
-              - Severe performance degradation making the application frustratingly slow.
-              - No straightforward workaround exists, or the workaround is difficult and non-obvious.
-              Qualifier: Is a key feature unusable or giving very wrong results?
-              Example: Gemini CLI enters a loop when making read-many-files tool call. I am unable to break out of the loop and gemini doesn't follow instructions subsequently.
-            P2: Medium
-              - A P2 bug is a moderately impactful issue. It's a noticeable problem but doesn't prevent the use of the software's main functionality.
-              Impact:
-              - Affects a non-critical feature or a smaller, specific subset of users.
-              - An inconvenient but functional workaround is available and easy to execute.
-              - Noticeable UI/UX problems that don't break functionality but look unprofessional (e.g., elements are misaligned or overlapping).
-              Qualifier: Is it an annoying but non-blocking problem?
-              Example: An error message is unclear or contains a typo, causing user confusion but not halting their workflow.
-            P3: Low
-              - A P3 bug is a minor, low-impact issue that is trivial or cosmetic. It has little to no effect on the overall functionality of the application.
-              Impact:
-              - Minor cosmetic issues like color inconsistencies, typos in documentation, or slight alignment problems on a non-critical page.
-              - An edge-case bug that is very difficult to reproduce and affects a tiny fraction of users.
-              Qualifier: Is it a "nice-to-fix" issue?
-              Example: Spelling mistakes etc.
+
+            Categorization Guidelines (Priority):
+            P0 - Urgent Blocking Issues:
+              - DO NOT APPLY THIS LABEL AUTOMATICALLY. Use status/manual-triage instead.
+              - Definition: Urgent, block a significant percentage of the user base, and prevent frequent use of the Gemini CLI.
+              - This includes core stability blockers (e.g., authentication failures, broken upgrades), critical crashes, and P0 security vulnerabilities.
+              - Impact: Blocks development or testing for the entire team; Major security vulnerability; Causes data loss or corruption with no workaround; Crashes the application or makes a core feature completely unusable for all or most users.
+              - Qualifier: Is the main function of the software broken?
+            P1 - High-Impact Issues:
+              - Definition: Affect a large number of users, blocking them from using parts of the Gemini CLI, or make the CLI frequently unusable even with workarounds available.
+              - Impact: A core feature is broken or behaving incorrectly for a large number of users or use cases; Severe performance degradation; No straightforward workaround exists.
+              - Qualifier: Is a key feature unusable or giving very wrong results?
+            P2 - Significant Issues:
+              - Definition: Affect some users significantly, such as preventing the use of certain features or authentication types.
+              - Can also be issues that many users complain about, causing annoyance or hindering daily use.
+              - Impact: Affects a non-critical feature or a smaller, specific subset of users; An inconvenient but functional workaround is available; Noticeable UI/UX problems that look unprofessional.
+              - Qualifier: Is it an annoying but non-blocking problem?
+            P3 - Low-Impact Issues:
+              - Definition: Typically usability issues that cause annoyance to a limited user base.
+              - Includes feature requests that could be addressed in the near future and may be suitable for community contributions.
+              - Impact: Minor cosmetic issues; An edge-case bug that is very difficult to reproduce and affects a tiny fraction of users.
+              - Qualifier: Is it a "nice-to-fix" issue?

             Additional Context:
-              - If users are talking about issues where the model gets downgraded from pro to flash then i want you to categorize that as a performance issue
-              - This product is designed to use different models eg.. using pro, downgrading to flash etc.
-              - When users report that they dont expect the model to change those would be categorized as feature requests.
-            Definition of Areas
-            area/ux:
-              - Issues concerning user-facing elements like command usability, interactive features, help docs, and perceived performance.
-              - I am seeing my screen flicker when using Gemini CLI
-              - I am seeing the output malformed

-              - i am not getting a response that is reasonable or expected. this can include things like
-              - I am calling a tool and the tool is not performing as expected.
-              - i am expecting a tool to be called and it is not getting called ,
-              - Including experience when using
-              - built-in tools (e.g., web search, code interpreter, read file, writefile, etc..),
-              - Function calling issues should be under this area
-              - i am getting responses from the model that are malformed.

-## Building and running
-
-Before submitting any changes, it is crucial to validate them by running the
-full preflight check. This command will build the repository, run all tests,
-check for type errors, and lint the code.
-
-To run the full suite of checks, execute the following command:
-
-```bash
-npm run preflight
-```
-
-This single command ensures that your changes meet all the quality gates of the
-project. While you can run the individual steps (`build`, `test`, `typecheck`,
-`lint`) separately, it is highly recommended to use `npm run preflight` to
-ensure a comprehensive validation.
-
-## Writing Tests
-
-This project uses **Vitest** as its primary testing framework. When writing
-tests, aim to follow existing patterns. Key conventions include:
-
-### Test Structure and Framework
-
-- **Framework**: All tests are written using Vitest (`describe`, `it`, `expect`,
-  `vi`).
-- **File Location**: Test files (`*.test.ts` for logic, `*.test.tsx` for React
-  components) are co-located with the source files they test.
-- **Configuration**: Test environments are defined in `vitest.config.ts` files.
-- **Setup/Teardown**: Use `beforeEach` and `afterEach`. Commonly,
-  `vi.resetAllMocks()` is called in `beforeEach` and `vi.restoreAllMocks()` in
-  `afterEach`.
-
-### Mocking (`vi` from Vitest)
-
-- **ES Modules**: Mock with
-  `vi.mock('module-name', async (importOriginal) => { ... })`. Use
-  `importOriginal` for selective mocking.
-  - _Example_:
-    `vi.mock('os', async (importOriginal) => { const actual = await importOriginal(); return { ...actual, homedir: vi.fn() }; });`
-- **Mocking Order**: For critical dependencies (e.g., `os`, `fs`) that affect
-  module-level constants, place `vi.mock` at the _very top_ of the test file,
-  before other imports.
-- **Hoisting**: Use `const myMock = vi.hoisted(() => vi.fn());` if a mock
-  function needs to be defined before its use in a `vi.mock` factory.
-- **Mock Functions**: Create with `vi.fn()`. Define behavior with
-  `mockImplementation()`, `mockResolvedValue()`, or `mockRejectedValue()`.
-- **Spying**: Use `vi.spyOn(object, 'methodName')`. Restore spies with
-  `mockRestore()` in `afterEach`.
-
-### Commonly Mocked Modules
-
-- **Node.js built-ins**: `fs`, `fs/promises`, `os` (especially `os.homedir()`),
-  `path`, `child_process` (`execSync`, `spawn`).
-- **External SDKs**: `@google/genai`, `@modelcontextprotocol/sdk`.
-- **Internal Project Modules**: Dependencies from other project packages are
-  often mocked.
-
-### React Component Testing (CLI UI - Ink)
-
-- Use `render()` from `ink-testing-library`.
-- Assert output with `lastFrame()`.
-- Wrap components in necessary `Context.Provider`s.
-- Mock custom React hooks and complex child components using `vi.mock()`.
-
-### Asynchronous Testing
-
-- Use `async/await`.
-- For timers, use `vi.useFakeTimers()`, `vi.advanceTimersByTimeAsync()`,
-  `vi.runAllTimersAsync()`.
-- Test promise rejections with `await expect(promise).rejects.toThrow(...)`.
-
-### General Guidance
-
-- When adding tests, first examine existing tests to understand and conform to
-  established conventions.
-- Pay close attention to the mocks at the top of existing test files; they
-  reveal critical dependencies and how they are managed in a test environment.
-
-## Git Repo
-
-The main branch for this project is called "main"
-
-## JavaScript/TypeScript
-
-When contributing to this React, Node, and TypeScript codebase, please
-prioritize the use of plain JavaScript objects with accompanying TypeScript
-interface or type declarations over JavaScript class syntax. This approach
-offers significant advantages, especially concerning interoperability with React
-and overall code maintainability.
-
-### Preferring Plain Objects over Classes
-
-JavaScript classes, by their nature, are designed to encapsulate internal state
-and behavior. While this can be useful in some object-oriented paradigms, it
-often introduces unnecessary complexity and friction when working with React's
-component-based architecture. Here's why plain objects are preferred:
-
-- Seamless React Integration: React components thrive on explicit props and
-  state management. Classes' tendency to store internal state directly within
-  instances can make prop and state propagation harder to reason about and
-  maintain. Plain objects, on the other hand, are inherently immutable (when
-  used thoughtfully) and can be easily passed as props, simplifying data flow
-  and reducing unexpected side effects.
-
-- Reduced Boilerplate and Increased Conciseness: Classes often promote the use
-  of constructors, this binding, getters, setters, and other boilerplate that
-  can unnecessarily bloat code. TypeScript interface and type declarations
-  provide powerful static type checking without the runtime overhead or
-  verbosity of class definitions. This allows for more succinct and readable
-  code, aligning with JavaScript's strengths in functional programming.
-
-- Enhanced Readability and Predictability: Plain objects, especially when their
-  structure is clearly defined by TypeScript interfaces, are often easier to
-  read and understand. Their properties are directly accessible, and there's no
-  hidden internal state or complex inheritance chains to navigate. This
-  predictability leads to fewer bugs and a more maintainable codebase.
-
-- Simplified Immutability: While not strictly enforced, plain objects encourage
-  an immutable approach to data. When you need to modify an object, you
-  typically create a new one with the desired changes, rather than mutating the
-  original. This pattern aligns perfectly with React's reconciliation process
-  and helps prevent subtle bugs related to shared mutable state.
-
-- Better Serialization and Deserialization: Plain JavaScript objects are
-  naturally easy to serialize to JSON and deserialize back, which is a common
-  requirement in web development (e.g., for API communication or local storage).
-  Classes, with their methods and prototypes, can complicate this process.
-
-### Embracing ES Module Syntax for Encapsulation
-
-Rather than relying on Java-esque private or public class members, which can be
-verbose and sometimes limit flexibility, we strongly prefer leveraging ES module
-syntax (`import`/`export`) for encapsulating private and public APIs.
-
-- Clearer Public API Definition: With ES modules, anything that is exported is
-  part of the public API of that module, while anything not exported is
-  inherently private to that module. This provides a very clear and explicit way
-  to define what parts of your code are meant to be consumed by other modules.
-
-- Enhanced Testability (Without Exposing Internals): By default, unexported
-  functions or variables are not accessible from outside the module. This
-  encourages you to test the public API of your modules, rather than their
-  internal implementation details. If you find yourself needing to spy on or
-  stub an unexported function for testing purposes, it's often a "code smell"
-  indicating that the function might be a good candidate for extraction into its
-  own separate, testable module with a well-defined public API. This promotes a
-  more robust and maintainable testing strategy.
-
-- Reduced Coupling: Explicitly defined module boundaries through import/export
-  help reduce coupling between different parts of your codebase. This makes it
-  easier to refactor, debug, and understand individual components in isolation.
-
-### Avoiding `any` Types and Type Assertions; Preferring `unknown`
-
-TypeScript's power lies in its ability to provide static type checking, catching
-potential errors before your code runs. To fully leverage this, it's crucial to
-avoid the `any` type and be judicious with type assertions.
-
-- **The Dangers of `any`**: Using any effectively opts out of TypeScript's type
-  checking for that particular variable or expression. While it might seem
-  convenient in the short term, it introduces significant risks:
-  - **Loss of Type Safety**: You lose all the benefits of type checking, making
-    it easy to introduce runtime errors that TypeScript would otherwise have
-    caught.
-  - **Reduced Readability and Maintainability**: Code with `any` types is harder
-    to understand and maintain, as the expected type of data is no longer
-    explicitly defined.
-  - **Masking Underlying Issues**: Often, the need for any indicates a deeper
-    problem in the design of your code or the way you're interacting with
-    external libraries. It's a sign that you might need to refine your types or
-    refactor your code.
-
-- **Preferring `unknown` over `any`**: When you absolutely cannot determine the
-  type of a value at compile time, and you're tempted to reach for any, consider
-  using unknown instead. unknown is a type-safe counterpart to any. While a
-  variable of type unknown can hold any value, you must perform type narrowing
-  (e.g., using typeof or instanceof checks, or a type assertion) before you can
-  perform any operations on it. This forces you to handle the unknown type
-  explicitly, preventing accidental runtime errors.
-
-  ```ts
-  function processValue(value: unknown) {
-    if (typeof value === 'string') {
-      // value is now safely a string
-      console.log(value.toUpperCase());
-    } else if (typeof value === 'number') {
-      // value is now safely a number
-      console.log(value * 2);
-    }
-    // Without narrowing, you cannot access properties or methods on 'value'
-    // console.log(value.someProperty); // Error: Object is of type 'unknown'.
-  }
-  ```
-
-- **Type Assertions (`as Type`) - Use with Caution**: Type assertions tell the
-  TypeScript compiler, "Trust me, I know what I'm doing; this is definitely of
-  this type." While there are legitimate use cases (e.g., when dealing with
-  external libraries that don't have perfect type definitions, or when you have
-  more information than the compiler), they should be used sparingly and with
-  extreme caution.
-  - **Bypassing Type Checking**: Like `any`, type assertions bypass TypeScript's
-    safety checks. If your assertion is incorrect, you introduce a runtime error
-    that TypeScript would not have warned you about.
-  - **Code Smell in Testing**: A common scenario where `any` or type assertions
-    might be tempting is when trying to test "private" implementation details
-    (e.g., spying on or stubbing an unexported function within a module). This
-    is a strong indication of a "code smell" in your testing strategy and
-    potentially your code structure. Instead of trying to force access to
-    private internals, consider whether those internal details should be
-    refactored into a separate module with a well-defined public API. This makes
-    them inherently testable without compromising encapsulation.
-
-### Type narrowing `switch` clauses
-
-Use the `checkExhaustive` helper in the default clause of a switch statement.
-This will ensure that all of the possible options within the value or
-enumeration are used.
-
-This helper method can be found in `packages/cli/src/utils/checks.ts`
-
-### Embracing JavaScript's Array Operators
-
-To further enhance code cleanliness and promote safe functional programming
-practices, leverage JavaScript's rich set of array operators as much as
-possible. Methods like `.map()`, `.filter()`, `.reduce()`, `.slice()`,
-`.sort()`, and others are incredibly powerful for transforming and manipulating
-data collections in an immutable and declarative way.
-
-Using these operators:
-
-- Promotes Immutability: Most array operators return new arrays, leaving the
-  original array untouched. This functional approach helps prevent unintended
-  side effects and makes your code more predictable.
-- Improves Readability: Chaining array operators often lead to more concise and
-  expressive code than traditional for loops or imperative logic. The intent of
-  the operation is clear at a glance.
-- Facilitates Functional Programming: These operators are cornerstones of
-  functional programming, encouraging the creation of pure functions that take
-  inputs and produce outputs without causing side effects. This paradigm is
-  highly beneficial for writing robust and testable code that pairs well with
-  React.
-
-By consistently applying these principles, we can maintain a codebase that is
-not only efficient and performant but also a joy to work with, both now and in
-the future.

-
-### Role
-
-You are a React assistant that helps users write more efficient and optimizable
-React code. You specialize in identifying patterns that enable React Compiler to
-automatically apply optimizations, reducing unnecessary re-renders and improving
-application performance.
-
-### Follow these guidelines in all code you produce and suggest
-
-Use functional components with Hooks: Do not generate class components or use
-old lifecycle methods. Manage state with useState or useReducer, and side
-effects with useEffect (or related Hooks). Always prefer functions and Hooks for
-any new component logic.
-
-Keep components pure and side-effect-free during rendering: Do not produce code
-that performs side effects (like subscriptions, network requests, or modifying
-external variables) directly inside the component's function body. Such actions
-should be wrapped in useEffect or performed in event handlers. Ensure your
-render logic is a pure function of props and state.
-
-Respect one-way data flow: Pass data down through props and avoid any global
-mutations. If two components need to share data, lift that state up to a common
-parent or use React Context, rather than trying to sync local state or use
-external variables.
-
-Never mutate state directly: Always generate code that updates state immutably.
-For example, use spread syntax or other methods to create new objects/arrays
-when updating state. Do not use assignments like state.someValue = ... or array
-mutations like array.push() on state variables. Use the state setter (setState
-from useState, etc.) to update state.
-
-Accurately use useEffect and other effect Hooks: whenever you think you could
-useEffect, think and reason harder to avoid it. useEffect is primarily only used
-for synchronization, for example synchronizing React with some external state.
-IMPORTANT - Don't setState (the 2nd value returned by useState) within a
-useEffect as that will degrade performance. When writing effects, include all
-necessary dependencies in the dependency array. Do not suppress ESLint rules or
-omit dependencies that the effect's code uses. Structure the effect callbacks to
-handle changing values properly (e.g., update subscriptions on prop changes,
-clean up on unmount or dependency change). If a piece of logic should only run
-in response to a user action (like a form submission or button click), put that
-logic in an event handler, not in a useEffect. Where possible, useEffects should
-return a cleanup function.
-
-Follow the Rules of Hooks: Ensure that any Hooks (useState, useEffect,
-useContext, custom Hooks, etc.) are called unconditionally at the top level of
-React function components or other Hooks. Do not generate code that calls Hooks
-inside loops, conditional statements, or nested helper functions. Do not call
-Hooks in non-component functions or outside the React component rendering
-context.
-
-Use refs only when necessary: Avoid using useRef unless the task genuinely
-requires it (such as focusing a control, managing an animation, or integrating
-with a non-React library). Do not use refs to store application state that
-should be reactive. If you do use refs, never write to or read from ref.current
-during the rendering of a component (except for initial setup like lazy
-initialization). Any ref usage should not affect the rendered output directly.
-
-Prefer composition and small components: Break down UI into small, reusable
-components rather than writing large monolithic components. The code you
-generate should promote clarity and reusability by composing components
-together. Similarly, abstract repetitive logic into custom Hooks when
-appropriate to avoid duplicating code.
-
-Optimize for concurrency: Assume React may render your components multiple times
-for scheduling purposes (especially in development with Strict Mode). Write code
-that remains correct even if the component function runs more than once. For
-instance, avoid side effects in the component body and use functional state
-updates (e.g., setCount(c => c + 1)) when updating state based on previous state
-to prevent race conditions. Always include cleanup functions in effects that
-subscribe to external resources. Don't write useEffects for "do this when this
-changes" side effects. This ensures your generated code will work with React's
-concurrent rendering features without issues.
-
-Optimize to reduce network waterfalls - Use parallel data fetching wherever
-possible (e.g., start multiple requests at once rather than one after another).
-Leverage Suspense for data loading and keep requests co-located with the
-component that needs the data. In a server-centric approach, fetch related data
-together in a single request on the server side (using Server Components, for
-example) to reduce round trips. Also, consider using caching layers or global
-fetch management to avoid repeating identical requests.
-
-Rely on React Compiler - useMemo, useCallback, and React.memo can be omitted if
-React Compiler is enabled. Avoid premature optimization with manual memoization.
-Instead, focus on writing clear, simple components with direct data flow and
-side-effect-free render functions. Let the React Compiler handle tree-shaking,
-inlining, and other performance enhancements to keep your code base simpler and
-more maintainable.
-
-Design for a good user experience - Provide clear, minimal, and non-blocking UI
-states. When data is loading, show lightweight placeholders (e.g., skeleton
-screens) rather than intrusive spinners everywhere. Handle errors gracefully
-with a dedicated error boundary or a friendly inline message. Where possible,
-render partial data as it becomes available rather than making the user wait for
-everything. Suspense allows you to declare the loading states in your component
-tree in a natural way, preventing “flash” states and improving perceived
-performance.
-
-### Process
-
-1. Analyze the user's code for optimization opportunities:
-   - Check for React anti-patterns that prevent compiler optimization
-   - Look for component structure issues that limit compiler effectiveness
-   - Think about each suggestion you are making and consult React docs for best
-     practices
-
-2. Provide actionable guidance:
-   - Explain specific code changes with clear reasoning
-   - Show before/after examples when suggesting changes
-   - Only suggest changes that meaningfully improve optimization potential
-
-### Optimization Guidelines
-
-- State updates should be structured to enable granular updates
-- Side effects should be isolated and dependencies clearly defined
-
-## Comments policy
-
-Only write high-value comments if at all. Avoid talking to the user through
-comments.
-
-## General style requirements
-
-Use hyphens instead of underscores in flag names (e.g. `my-flag` instead of
-`my_flag`).
+# Gemini CLI Project Context
+
+Gemini CLI is an open-source AI agent that brings the power of Gemini directly
+into the terminal. It is designed to be a terminal-first, extensible, and
+powerful tool for developers.
+
+## Project Overview
+
+- **Purpose:** Provide a seamless terminal interface for Gemini models,
+  supporting code understanding, generation, automation, and integration via MCP
+  (Model Context Protocol).
+- **Main Technologies:**
+  - **Runtime:** Node.js (>=20.0.0, recommended ~20.19.0 for development)
+  - **Language:** TypeScript
+  - **UI Framework:** React (using [Ink](https://github.com/vadimdemedes/ink)
+    for CLI rendering)
+  - **Testing:** Vitest
+  - **Bundling:** esbuild
+  - **Linting/Formatting:** ESLint, Prettier
+- **Architecture:** Monorepo structure using npm workspaces.
+  - `packages/cli`: User-facing terminal UI, input processing, and display
+    rendering.
+  - `packages/core`: Backend logic, Gemini API orchestration, prompt
+    construction, and tool execution.
+  - `packages/core/src/tools/`: Built-in tools for file system, shell, and web
+    operations.
+  - `packages/a2a-server`: Experimental Agent-to-Agent server.
+  - `packages/vscode-ide-companion`: VS Code extension pairing with the CLI.
+
+## Building and Running
+
+- **Install Dependencies:** `npm install`
+- **Build All:** `npm run build:all` (Builds packages, sandbox, and VS Code
+  companion)
+- **Build Packages:** `npm run build`
+- **Run in Development:** `npm run start`
+- **Run in Debug Mode:** `npm run debug` (Enables Node.js inspector)
+- **Bundle Project:** `npm run bundle`
+- **Clean Artifacts:** `npm run clean`
+
+## Testing and Quality
+
+- **Test Commands:**
+  - **Unit (All):** `npm run test`
+  - **Integration (E2E):** `npm run test:e2e`
+  - **Workspace-Specific:** `npm test -w <pkg> -- <path>` (Note: `<path>` must
+    be relative to the workspace root, e.g.,
+    `-w @google/gemini-cli-core -- src/routing/modelRouterService.test.ts`)
+- **Full Validation:** `npm run preflight` (Heaviest check; runs clean, install,
+  build, lint, type check, and tests. Recommended before submitting PRs.)
+- **Individual Checks:** `npm run lint` / `npm run format` / `npm run typecheck`
+
+## Development Conventions
+
+- **Contributions:** Follow the process outlined in `CONTRIBUTING.md`. Requires
+  signing the Google CLA.
+- **Pull Requests:** Keep PRs small, focused, and linked to an existing issue.
+- **Commit Messages:** Follow the
+  [Conventional Commits](https://www.conventionalcommits.org/) standard.
+- **Coding Style:** Adhere to existing patterns in `packages/cli` (React/Ink)
+  and `packages/core` (Backend logic).
+- **Imports:** Use specific imports and avoid restricted relative imports
+  between packages (enforced by ESLint).
+
+## Testing Conventions
+
+- **Environment Variables:** When testing code that depends on environment
+  variables, use `vi.stubEnv('NAME', 'value')` in `beforeEach` and
+  `vi.unstubAllEnvs()` in `afterEach`. Avoid modifying `process.env` directly as
+  it can lead to test leakage and is less reliable. To "unset" a variable, use
+  an empty string `vi.stubEnv('NAME', '')`.
+
+## Documentation
+
+- Always use the `docs-writer` skill when you are asked to write, edit, or
+  review any documentation.
+- Documentation is located in the `docs/` directory.
+- Suggest documentation updates when code changes render existing documentation
+  obsolete or incomplete.

+### Ralph Wiggum Mode (Iterative Automation)
+
+Ralph Wiggum mode is an advanced automation feature that allows Gemini CLI to
+repeatedly execute a prompt in a loop until a specific goal is achieved. This is
+ideal for tasks like fixing failing tests or complex refactoring.
+
+To use Ralph Wiggum mode, provide a prompt and a **completion promise** (a
+string to look for in the output). The CLI will:
+
+1.  Enter **YOLO mode** to auto-approve all tool calls.
+2.  Run the prompt and check the response for your completion string.
+3.  If not found, it repeats the process up to a specified **max iterations**.
+4.  **Persistent Context**: It uses a **memory file** (`memories.md` by default)
+    to pass notes between iterations. **Note:** Use a unique `--memory-file` for
+    different tasks in the same directory to ensure context isolation.
+
+```bash
+gemini -p "Fix the failing tests in this repo" \
+  --ralph-wiggum \
+  --completion-promise "ALL TESTS PASSED" \
+  --max-iterations 5 \
+  --memory-file "task-fix-tests.md"
+```
+
+At the end of the run, a summary table displays the result of each iteration and
+extracted test statistics.

+  granular allowlisting for shell commands has been implemented, providing finer
+  control over tool execution.
+  ([#15943](https://github.com/google-gemini/gemini-cli/pull/15943) by

+  to refresh skill definitions, and `/skills install/uninstall` for easier
+  management of your Agent Skills.

+
+For most users, our latest stable release is the recommended release. Install
+the latest stable version with:
+
+```
+npm install -g @google/gemini-cli
+```
+
+## Highlights
+
+- **Enhanced Agent and Skill Capabilities:** This release introduces the new
+  `skill-creator` built-in skill, enables Agent Skills by default, and adds a
+  generalist agent to improve task routing. Security for skill installation has
+  also been enhanced with new consent prompts.
+- **Improved UI and UX:** A new "Rewind" feature lets you walk back through
+  conversation history. We've also added an `/introspect` command for debugging
+  and unified various shell confirmation dialogs for a more consistent user
+  experience.
+- **Core Stability and Performance:** This release includes significant
+  performance improvements, including a fix for PDF token estimation,
+  optimizations for large inputs, and prevention of OOM crashes. Key memory
+  management components like `LRUCache` have also been updated.
+- **Scheduler and Policy Refactoring:** The core tool scheduler has been
+  decoupled into distinct orchestration, policy, and confirmation components,
+  and we've added an experimental event-driven scheduler to improve performance
+  and reliability.

-# Gemini CLI Configuration
-
-Gemini CLI offers several ways to configure its behavior, including environment
-variables, command-line arguments, and settings files. This document outlines
-the different configuration methods and available settings.
-
-## Configuration layers
-
-Configuration is applied in the following order of precedence (lower numbers are
-overridden by higher numbers):
-
-1.  **Default values:** Hardcoded defaults within the application.
-2.  **User settings file:** Global settings for the current user.
-3.  **Project settings file:** Project-specific settings.
-4.  **System settings file:** System-wide settings.
-5.  **Environment variables:** System-wide or session-specific variables,
-    potentially loaded from `.env` files.
-6.  **Command-line arguments:** Values passed when launching the CLI.
-
-## Settings files
-
-Gemini CLI uses `settings.json` files for persistent configuration. There are
-three locations for these files:
-
-- **User settings file:**
-  - **Location:** `~/.gemini/settings.json` (where `~` is your home directory).
-  - **Scope:** Applies to all Gemini CLI sessions for the current user.
-- **Project settings file:**
-  - **Location:** `.gemini/settings.json` within your project's root directory.
-  - **Scope:** Applies only when running Gemini CLI from that specific project.
-    Project settings override user settings.
-- **System settings file:**
-  - **Location:** `/etc/gemini-cli/settings.json` (Linux),
-    `C:\ProgramData\gemini-cli\settings.json` (Windows) or
-    `/Library/Application Support/GeminiCli/settings.json` (macOS). The path can
-    be overridden using the `GEMINI_CLI_SYSTEM_SETTINGS_PATH` environment
-    variable.
-  - **Scope:** Applies to all Gemini CLI sessions on the system, for all users.
-    System settings override user and project settings. May be useful for system
-    administrators at enterprises to have controls over users' Gemini CLI
-    setups.
-
-**Note on environment variables in settings:** String values within your
-`settings.json` files can reference environment variables using either
-`$VAR_NAME` or `${VAR_NAME}` syntax. These variables will be automatically
-resolved when the settings are loaded. For example, if you have an environment
-variable `MY_API_TOKEN`, you could use it in `settings.json` like this:
-`"apiKey": "$MY_API_TOKEN"`.
-
-### The `.gemini` directory in your project
-
-In addition to a project settings file, a project's `.gemini` directory can
-contain other project-specific files related to Gemini CLI's operation, such as:
-
-- [Custom sandbox profiles](#sandboxing) (e.g.,
-  `.gemini/sandbox-macos-custom.sb`, `.gemini/sandbox.Dockerfile`).
-
-### Available settings in `settings.json`:
-
-- **`contextFileName`** (string or array of strings):
-  - **Description:** Specifies the filename for context files (e.g.,
-    `GEMINI.md`, `AGENTS.md`). Can be a single filename or a list of accepted
-    filenames.
-  - **Default:** `GEMINI.md`
-  - **Example:** `"contextFileName": "AGENTS.md"`
-
-- **`bugCommand`** (object):
-  - **Description:** Overrides the default URL for the `/bug` command.
-  - **Default:**
-    `"urlTemplate": "https://github.com/google-gemini/gemini-cli/issues/new?template=bug_report.yml&title={title}&info={info}"`
-  - **Properties:**
-    - **`urlTemplate`** (string): A URL that can contain `{title}` and `{info}`
-      placeholders.
-  - **Example:**
-    ```json
-    "bugCommand": {
-      "urlTemplate": "https://bug.example.com/new?title={title}&info={info}"
-    }
-    ```
-
-- **`fileFiltering`** (object):
-  - **Description:** Controls git-aware file filtering behavior for @ commands
-    and file discovery tools.
-  - **Default:** `"respectGitIgnore": true, "enableRecursiveFileSearch": true`
-  - **Properties:**
-    - **`respectGitIgnore`** (boolean): Whether to respect .gitignore patterns
-      when discovering files. When set to `true`, git-ignored files (like
-      `node_modules/`, `dist/`, `.env`) are automatically excluded from @
-      commands and file listing operations.
-    - **`enableRecursiveFileSearch`** (boolean): Whether to enable searching
-      recursively for filenames under the current tree when completing @
-      prefixes in the prompt.
-  - **Example:**
-    ```json
-    "fileFiltering": {
-      "respectGitIgnore": true,
-      "enableRecursiveFileSearch": false
-    }
-    ```
-
-- **`coreTools`** (array of strings):
-  - **Description:** Allows you to specify a list of core tool names that should
-    be made available to the model. This can be used to restrict the set of
-    built-in tools. See [Built-in Tools](../core/tools-api.md#built-in-tools)
-    for a list of core tools. You can also specify command-specific restrictions
-    for tools that support it, like the `ShellTool`. For example,
-    `"coreTools": ["ShellTool(ls -l)"]` will only allow the `ls -l` command to
-    be executed.
-  - **Default:** All tools available for use by the Gemini model.
-  - **Example:** `"coreTools": ["ReadFileTool", "GlobTool", "ShellTool(ls)"]`.
-
-- **`excludeTools`** (array of strings):
-  - **Description:** Allows you to specify a list of core tool names that should
-    be excluded from the model. A tool listed in both `excludeTools` and
-    `coreTools` is excluded. You can also specify command-specific restrictions
-    for tools that support it, like the `ShellTool`. For example,
-    `"excludeTools": ["ShellTool(rm -rf)"]` will block the `rm -rf` command.
-  - **Default**: No tools excluded.
-  - **Example:** `"excludeTools": ["run_shell_command", "findFiles"]`.
-  - **Security Note:** Command-specific restrictions in `excludeTools` for
-    `run_shell_command` are based on simple string matching and can be easily
-    bypassed. This feature is **not a security mechanism** and should not be
-    relied upon to safely execute untrusted code. It is recommended to use
-    `coreTools` to explicitly select commands that can be executed.
-
-- **`allowMCPServers`** (array of strings):
-  - **Description:** Allows you to specify a list of MCP server names that
-    should be made available to the model. This can be used to restrict the set
-    of MCP servers to connect to. Note that this will be ignored if
-    `--allowed-mcp-server-names` is set.
-  - **Default:** All MCP servers are available for use by the Gemini model.
-  - **Example:** `"allowMCPServers": ["myPythonServer"]`.
-  - **Security Note:** This uses simple string matching on MCP server names,
-    which can be modified. If you're a system administrator looking to prevent
-    users from bypassing this, consider configuring the `mcpServers` at the
-    system settings level such that the user will not be able to configure any
-    MCP servers of their own. This should not be used as an airtight security
-    mechanism.
-
-- **`excludeMCPServers`** (array of strings):
-  - **Description:** Allows you to specify a list of MCP server names that
-    should be excluded from the model. A server listed in both
-    `excludeMCPServers` and `allowMCPServers` is excluded. Note that this will
-    be ignored if `--allowed-mcp-server-names` is set.
-  - **Default**: No MCP servers excluded.
-  - **Example:** `"excludeMCPServers": ["myNodeServer"]`.
-  - **Security Note:** This uses simple string matching on MCP server names,
-    which can be modified. If you're a system administrator looking to prevent
-    users from bypassing this, consider configuring the `mcpServers` at the
-    system settings level such that the user will not be able to configure any
-    MCP servers of their own. This should not be used as an airtight security
-    mechanism.
-
-- **`autoAccept`** (boolean):
-  - **Description:** Controls whether the CLI automatically accepts and executes
-    tool calls that are considered safe (e.g., read-only operations) without
-    explicit user confirmation. If set to `true`, the CLI will bypass the
-    confirmation prompt for tools deemed safe.
-  - **Default:** `false`
-  - **Example:** `"autoAccept": true`
-
-- **`theme`** (string):
-  - **Description:** Sets the visual [theme](./themes.md) for Gemini CLI.
-  - **Default:** `"Default"`

-    with NORMAL and INSERT modes. The vim mode status is displayed in the footer
-    and persists between sessions.
-  - **Default:** `false`
-  - **Example:** `"vimMode": true`
-
-- **`sandbox`** (boolean or string):
-  - **Description:** Controls whether and how to use sandboxing for tool
-    execution. If set to `true`, Gemini CLI uses a pre-built
-    `gemini-cli-sandbox` Docker image. For more information, see
-    [Sandboxing](#sandboxing).

-    Tool wrappers are optional.
-  - **Default:** Empty
-  - **Example:** `"toolDiscoveryCommand": "bin/get_tools"`
-
-- **`toolCallCommand`** (string):
-  - **Description:** Defines a custom shell command for calling a specific tool
-    that was discovered using `toolDiscoveryCommand`. The shell command must
-    meet the following criteria:
-    - It must take function `name` (exactly as in
-      [function declaration](https://ai.google.dev/gemini-api/docs/function-calling#function-declarations))
-      as first command line argument.
-    - It must read function arguments as JSON on `stdin`, analogous to
-      [`functionCall.args`](https://cloud.google.com/vertex-ai/generative-ai/docs/model-reference/inference#functioncall).
-    - It must return function output as JSON on `stdout`, analogous to
-      [`functionResponse.response.content`](https://cloud.google.com/vertex-ai/generative-ai/docs/model-reference/inference#functionresponse).
-  - **Default:** Empty
-  - **Example:** `"toolCallCommand": "bin/call_tool"`
-
-- **`mcpServers`** (object):
-  - **Description:** Configures connections to one or more Model-Context
-    Protocol (MCP) servers for discovering and using custom tools. Gemini CLI
-    attempts to connect to each configured MCP server to discover available
-    tools. If multiple MCP servers expose a tool with the same name, the tool
-    names will be prefixed with the server alias you defined in the
-    configuration (e.g., `serverAlias__actualToolName`) to avoid conflicts. Note
-    that the system might strip certain schema properties from MCP tool
-    definitions for compatibility.
-  - **Default:** Empty

-        this MCP server.
-      - `trust` (boolean, optional): Trust this server and bypass all tool call
-        confirmations.
-      - `includeTools` (array of strings, optional): List of tool names to
-        include from this MCP server. When specified, only the tools listed here
-        will be available from this server (whitelist behavior). If not
-        specified, all tools from the server are enabled by default.
-      - `excludeTools` (array of strings, optional): List of tool names to
-        exclude from this MCP server. Tools listed here will not be available to
-        the model, even if they are exposed by the server. **Note:**
-        `excludeTools` takes precedence over `includeTools` - if a tool is in
-        both lists, it will be excluded.
-  - **Example:**
-    ```json
-    "mcpServers": {
-      "myPythonServer": {
-        "command": "python",
-        "args": ["mcp_server.py", "--port", "8080"],

-}
-```
-
-## Shell History
-
-The CLI keeps a history of shell commands you run. To avoid conflicts between
-different projects, this history is stored in a project-specific directory
-within your user's home folder.
-
-- **Location:** `~/.gemini/tmp/<project_hash>/shell_history`
-  - `<project_hash>` is a unique identifier generated from your project's root
-    path.
-  - The history is stored in a file named `shell_history`.
-
-## Environment Variables & `.env` Files
-
-Environment variables are a common way to configure applications, especially for
-sensitive information like API keys or for settings that might change between
-environments.
-
-The CLI automatically loads environment variables from an `.env` file. The
-loading order is:
-
-1.  `.env` file in the current working directory.
-2.  If not found, it searches upwards in parent directories until it finds an
-    `.env` file or reaches the project root (identified by a `.git` folder) or
-    the home directory.
-3.  If still not found, it looks for `~/.env` (in the user's home directory).
-
-**Environment Variable Exclusion:** Some environment variables (like `DEBUG` and
-`DEBUG_MODE`) are automatically excluded from being loaded from project `.env`
-files to prevent interference with gemini-cli behavior. Variables from
-`.gemini/.env` files are never excluded. You can customize this behavior using
-the `excludedProjectEnvVars` setting in your `settings.json` file.
-
-- **`GEMINI_API_KEY`** (Required):
-  - Your API key for the Gemini API.
-  - **Crucial for operation.** The CLI will not function without it.
-  - Set this in your shell profile (e.g., `~/.bashrc`, `~/.zshrc`) or an `.env`
-    file.
-- **`GEMINI_MODEL`**:
-  - Specifies the default Gemini model to use.
-  - Overrides the hardcoded default
-  - Example: `export GEMINI_MODEL="gemini-2.5-flash"`
-- **`GOOGLE_API_KEY`**:
-  - Your Google Cloud API key.
-  - Required for using Vertex AI in express mode.
-  - Ensure you have the necessary permissions.
-  - Example: `export GOOGLE_API_KEY="YOUR_GOOGLE_API_KEY"`.
-- **`GOOGLE_CLOUD_PROJECT`**:
-  - Your Google Cloud Project ID.
-  - Required for using Code Assist or Vertex AI.
-  - If using Vertex AI, ensure you have the necessary permissions in this
-    project.
-  - **Cloud Shell Note:** When running in a Cloud Shell environment, this
-    variable defaults to a special project allocated for Cloud Shell users. If
-    you have `GOOGLE_CLOUD_PROJECT` set in your global environment in Cloud
-    Shell, it will be overridden by this default. To use a different project in
-    Cloud Shell, you must define `GOOGLE_CLOUD_PROJECT` in a `.env` file.
-  - Example: `export GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"`.
-- **`GOOGLE_APPLICATION_CREDENTIALS`** (string):
-  - **Description:** The path to your Google Application Credentials JSON file.
-  - **Example:**
-    `export GOOGLE_APPLICATION_CREDENTIALS="/path/to/your/credentials.json"`
-- **`OTLP_GOOGLE_CLOUD_PROJECT`**:
-  - Your Google Cloud Project ID for Telemetry in Google Cloud
-  - Example: `export OTLP_GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"`.
-- **`GOOGLE_CLOUD_LOCATION`**:
-  - Your Google Cloud Project Location (e.g., us-central1).
-  - Required for using Vertex AI in non express mode.
-  - Example: `export GOOGLE_CLOUD_LOCATION="YOUR_PROJECT_LOCATION"`.
-- **`GEMINI_SANDBOX`**:
-  - Alternative to the `sandbox` setting in `settings.json`.
-  - Accepts `true`, `false`, `docker`, `podman`, or a custom command string.
-- **`SEATBELT_PROFILE`** (macOS specific):
-  - Switches the Seatbelt (`sandbox-exec`) profile on macOS.
-  - `permissive-open`: (Default) Restricts writes to the project folder (and a
-    few other folders, see
-    `packages/cli/src/utils/sandbox-macos-permissive-open.sb`) but allows other
-    operations.
-  - `strict`: Uses a strict profile that declines operations by default.
-  - `<profile_name>`: Uses a custom profile. To define a custom profile, create
-    a file named `sandbox-macos-<profile_name>.sb` in your project's `.gemini/`
-    directory (e.g., `my-project/.gemini/sandbox-macos-custom.sb`).
-- **`DEBUG` or `DEBUG_MODE`** (often used by underlying libraries or the CLI
-  itself):
-  - Set to `true` or `1` to enable verbose debug logging, which can be helpful
-    for troubleshooting.
-  - **Note:** These variables are automatically excluded from project `.env`
-    files by default to prevent interference with gemini-cli behavior. Use
-    `.gemini/.env` files if you need to set these for gemini-cli specifically.
-- **`NO_COLOR`**:
-  - Set to any value to disable all color output in the CLI.
-- **`CLI_TITLE`**:
-  - Set to a string to customize the title of the CLI.
-- **`CODE_ASSIST_ENDPOINT`**:
-  - Specifies the endpoint for the code assist server.
-  - This is useful for development and testing.
-- **`GEMINI_SYSTEM_MD`**:
-  - Overrides the base system prompt with the contents of a Markdown file.
-  - If set to `1` or `true`, it uses the file at `.gemini/system.md`.
-  - If set to a file path, it uses that file. The path can be absolute or
-    relative. `~` is supported for the home directory.
-  - The specified file must exist.
-- **`GEMINI_WRITE_SYSTEM_MD`**:
-  - Writes the default system prompt to a file. This is useful for getting a
-    template to customize.
-  - If set to `1` or `true`, it writes to `.gemini/system.md`.
-  - If set to a file path, it writes to that path. The path can be absolute or
-    relative. `~` is supported for the home directory. **Note: This will
-    overwrite the file if it already exists.**
-

-
-## Context Files (Hierarchical Instructional Context)
-
-While not strictly configuration for the CLI's _behavior_, context files
-(defaulting to `GEMINI.md` but configurable via the `contextFileName` setting)
-are crucial for configuring the _instructional context_ (also referred to as
-"memory") provided to the Gemini model. This powerful feature allows you to give
-project-specific instructions, coding style guides, or any relevant background
-information to the AI, making its responses more tailored and accurate to your
-needs. The CLI includes UI elements, such as an indicator in the footer showing
-the number of loaded context files, to keep you informed about the active
-context.
-
-- **Purpose:** These Markdown files contain instructions, guidelines, or context
-  that you want the Gemini model to be aware of during your interactions. The
-  system is designed to manage this instructional context hierarchically.
-
-### Example Context File Content (e.g., `GEMINI.md`)
-
-Here's a conceptual example of what a context file at the root of a TypeScript
-project might contain:
-
-```markdown
-# Project: My Awesome TypeScript Library
-
-## General Instructions:
-
-- When generating new TypeScript code, please follow the existing coding style.
-- Ensure all new functions and classes have JSDoc comments.
-- Prefer functional programming paradigms where appropriate.
-- All code should be compatible with TypeScript 5.0 and Node.js 20+.
-
-## Coding Style:
-
-- Use 2 spaces for indentation.
-- Interface names should be prefixed with `I` (e.g., `IUserService`).
-- Private class members should be prefixed with an underscore (`_`).
-- Always use strict equality (`===` and `!==`).
-
-## Specific Component: `src/api/client.ts`
-
-- This file handles all outbound API requests.
-- When adding new API call functions, ensure they include robust error handling
-  and logging.
-- Use the existing `fetchWithRetry` utility for all GET requests.
-
-## Regarding Dependencies:
-
-- Avoid introducing new external dependencies unless absolutely necessary.
-- If a new dependency is required, please state the reason.
-```
-
-This example demonstrates how you can provide general project context, specific
-coding conventions, and even notes about particular files or components. The
-more relevant and precise your context files are, the better the AI can assist
-you. Project-specific context files are highly encouraged to establish
-conventions and context.
-
-- **Hierarchical Loading and Precedence:** The CLI implements a sophisticated
-  hierarchical memory system by loading context files (e.g., `GEMINI.md`) from
-  several locations. Content from files lower in this list (more specific)
-  typically overrides or supplements content from files higher up (more
-  general). The exact concatenation order and final context can be inspected
-  using the `/memory show` command. The typical loading order is:
-  1.  **Global Context File:**
-      - Location: `~/.gemini/<contextFileName>` (e.g., `~/.gemini/GEMINI.md` in
-        your user home directory).
-      - Scope: Provides default instructions for all your projects.
-  2.  **Project Root & Ancestors Context Files:**
-      - Location: The CLI searches for the configured context file in the
-        current working directory and then in each parent directory up to either
-        the project root (identified by a `.git` folder) or your home directory.
-      - Scope: Provides context relevant to the entire project or a significant
-        portion of it.
-  3.  **Sub-directory Context Files (Contextual/Local):**
-      - Location: The CLI also scans for the configured context file in
-        subdirectories _below_ the current working directory (respecting common
-        ignore patterns like `node_modules`, `.git`, etc.). The breadth of this
-        search is limited to 200 directories by default, but can be configured
-        with a `memoryDiscoveryMaxDirs` field in your `settings.json` file.
-      - Scope: Allows for highly specific instructions relevant to a particular
-        component, module, or subsection of your project.
-- **Concatenation & UI Indication:** The contents of all found context files are
-  concatenated (with separators indicating their origin and path) and provided
-  as part of the system prompt to the Gemini model. The CLI footer displays the
-  count of loaded context files, giving you a quick visual cue about the active
-  instructional context.
-- **Importing Content:** You can modularize your context files by importing
-  other Markdown files using the `@path/to/file.md` syntax. For more details,
-  see the [Memory Import Processor documentation](../core/memport.md).
-- **Commands for Memory Management:**
-  - Use `/memory refresh` to force a re-scan and reload of all context files
-    from all configured locations. This updates the AI's instructional context.
-  - Use `/memory show` to display the combined instructional context currently
-    loaded, allowing you to verify the hierarchy and content being used by the
-    AI.
-  - See the [Commands documentation](./commands.md#memory) for full details on
-    the `/memory` command and its sub-commands (`show` and `refresh`).
-
-By understanding and utilizing these configuration layers and the hierarchical
-nature of context files, you can effectively manage the AI's memory and tailor
-the Gemini CLI's responses to your specific needs and projects.
-
-## Sandboxing
-
-The Gemini CLI can execute potentially unsafe operations (like shell commands
-and file modifications) within a sandboxed environment to protect your system.
-
-Sandboxing is disabled by default, but you can enable it in a few ways:
-
-- Using `--sandbox` or `-s` flag.
-- Setting `GEMINI_SANDBOX` environment variable.
-- Sandbox is enabled in `--yolo` mode by default.
-
-By default, it uses a pre-built `gemini-cli-sandbox` Docker image.
-
-For project-specific sandboxing needs, you can create a custom Dockerfile at
-`.gemini/sandbox.Dockerfile` in your project's root directory. This Dockerfile
-can be based on the base sandbox image:
-
-```dockerfile
-FROM gemini-cli-sandbox
-
-# Add your custom dependencies or configurations here
-# For example:
-# RUN apt-get update && apt-get install -y some-package
-# COPY ./my-config /app/my-config
-```
-
-When `.gemini/sandbox.Dockerfile` exists, you can use `BUILD_SANDBOX`
-environment variable when running Gemini CLI to automatically build the custom
-sandbox image:
-
-```bash
-BUILD_SANDBOX=1 gemini -s
-```
-
-## Usage Statistics
-
-To help us improve the Gemini CLI, we collect anonymized usage statistics. This
-data helps us understand how the CLI is used, identify common issues, and
-prioritize new features.
-
-**What we collect:**
-
-- **Tool Calls:** We log the names of the tools that are called, whether they
-  succeed or fail, and how long they take to execute. We do not collect the
-  arguments passed to the tools or any data returned by them.
-- **API Requests:** We log the Gemini model used for each request, the duration
-  of the request, and whether it was successful. We do not collect the content
-  of the prompts or responses.
-- **Session Information:** We collect information about the configuration of the
-  CLI, such as the enabled tools and the approval mode.
-
-**What we DON'T collect:**
-
-- **Personally Identifiable Information (PII):** We do not collect any personal
-  information, such as your name, email address, or API keys.
-- **Prompt and Response Content:** We do not log the content of your prompts or
-  the responses from the Gemini model.
-- **File Content:** We do not log the content of any files that are read or
-  written by the CLI.
-
-**How to opt out:**
-
-You can opt out of usage statistics collection at any time by setting the
-`usageStatisticsEnabled` property to `false` in your `settings.json` file:
-
-```json
-{
-  "usageStatisticsEnabled": false

+# Creating Agent Skills
+
+This guide provides an overview of how to create your own Agent Skills to extend
+the capabilities of Gemini CLI.
+
+## Getting started: The `skill-creator` skill
+
+The recommended way to create a new skill is to use the built-in `skill-creator`
+skill. To use it, ask Gemini CLI to create a new skill for you.
+
+**Example prompt:**
+
+> "create a new skill called 'code-reviewer'"
+
+Gemini CLI will then use the `skill-creator` to generate the skill:
+
+1.  Generate a new directory for your skill (e.g., `my-new-skill/`).
+2.  Create a `SKILL.md` file with the necessary YAML frontmatter (`name` and
+    `description`).
+3.  Create the standard resource directories: `scripts/`, `references/`, and
+    `assets/`.
+
+## Manual skill creation
+
+If you prefer to create skills manually:
+
+1.  **Create a directory** for your skill (e.g., `my-new-skill/`).
+2.  **Create a `SKILL.md` file** inside the new directory.
+
+To add additional resources that support the skill, refer to the skill
+structure.
+
+## Skill structure
+
+A skill is a directory containing a `SKILL.md` file at its root.
+
+### Folder structure
+
+While a `SKILL.md` file is the only required component, we recommend the
+following structure for organizing your skill's resources:
+
+```text
+my-skill/
+├── SKILL.md       (Required) Instructions and metadata
+├── scripts/       (Optional) Executable scripts
+├── references/    (Optional) Static documentation
+└── assets/        (Optional) Templates and other resources
+```
+
+### `SKILL.md` file
+
+The `SKILL.md` file is the core of your skill. This file uses YAML frontmatter
+for metadata and Markdown for instructions. For example:
+
+```markdown
+---
+name: code-reviewer
+description:
+  Use this skill to review code. It supports both local changes and remote Pull
+  Requests.
+---
+
+# Code Reviewer
+
+This skill guides the agent in conducting thorough code reviews.
+
+## Workflow
+
+### 1. Determine Review Target
+
+- **Remote PR**: If the user gives a PR number or URL, target that remote PR.
+- **Local Changes**: If changes are local... ...
+```
+
+- **`name`**: A unique identifier for the skill. This should match the directory
+  name.
+- **`description`**: A description of what the skill does and when Gemini should
+  use it.
+- **Body**: The Markdown body of the file contains the instructions that guide
+  the agent's behavior when the skill is active.

-## Restricting Tool Access
+### Enforcing system settings with a wrapper script
+
+While the `GEMINI_CLI_SYSTEM_SETTINGS_PATH` environment variable provides
+flexibility, a user could potentially override it to point to a different
+settings file, bypassing the centrally managed configuration. To mitigate this,
+enterprises can deploy a wrapper script or alias that ensures the environment
+variable is always set to the corporate-controlled path.
+
+This approach ensures that no matter how the user calls the `gemini` command,
+the enterprise settings are always loaded with the highest precedence.
+
+**Example wrapper script:**
+
+Administrators can create a script named `gemini` and place it in a directory
+that appears earlier in the user's `PATH` than the actual Gemini CLI binary
+(e.g., `/usr/local/bin/gemini`).
+
+```bash
+#!/bin/bash
+
+# Enforce the path to the corporate system settings file.
+# This ensures that the company's configuration is always applied.
+export GEMINI_CLI_SYSTEM_SETTINGS_PATH="/etc/gemini-cli/settings.json"
+
+# Find the original gemini executable.
+# This is a simple example; a more robust solution might be needed
+# depending on the installation method.
+REAL_GEMINI_PATH=$(type -aP gemini | grep -v "^$(type -P gemini)$" | head -n 1)
+
+if [ -z "$REAL_GEMINI_PATH" ]; then
+  echo "Error: The original 'gemini' executable was not found." >&2
+  exit 1
+fi
+
+# Pass all arguments to the real Gemini CLI executable.
+exec "$REAL_GEMINI_PATH" "$@"
+```
+
+By deploying this script, the `GEMINI_CLI_SYSTEM_SETTINGS_PATH` is set within
+the script's environment, and the `exec` command replaces the script process
+with the actual Gemini CLI process, which inherits the environment variable.
+This makes it significantly more difficult for a user to bypass the enforced
+settings.
+
+## User isolation in shared environments
+
+In shared compute environments (like ML experiment runners or shared build
+servers), you can isolate Gemini CLI state by overriding the user's home
+directory.
+
+By default, Gemini CLI stores configuration and history in `~/.gemini`. You can
+use the `GEMINI_CLI_HOME` environment variable to point to a unique directory
+for a specific user or job. The CLI will create a `.gemini` folder inside the
+specified path.

+### Restricting logins to corporate domains
+
+For enterprises using Google Workspace, you can enforce that users only
+authenticate with their corporate Google accounts. This is a network-level
+control that is configured on a proxy server, not within Gemini CLI itself. It
+works by intercepting authentication requests to Google and adding a special
+HTTP header.
+
+This policy prevents users from logging in with personal Gmail accounts or other
+non-corporate Google accounts.
+
+For detailed instructions, see the Google Workspace Admin Help article on

+
+The general steps are as follows:
+
+1.  **Intercept Requests**: Configure your web proxy to intercept all requests
+    to `google.com`.
+2.  **Add HTTP Header**: For each intercepted request, add the
+    `X-GoogApps-Allowed-Domains` HTTP header.
+3.  **Specify Domains**: The value of the header should be a comma-separated
+    list of your approved Google Workspace domain names.
+
+**Example header:**
+
+```
+X-GoogApps-Allowed-Domains: my-corporate-domain.com, secondary-domain.com
+```
+

+logins from accounts belonging to the specified domains.

+# Advanced Model Configuration
+
+This guide details the Model Configuration system within the Gemini CLI.
+Designed for researchers, AI quality engineers, and advanced users, this system
+provides a rigorous framework for managing generative model hyperparameters and
+behaviors.
+
+> **Warning**: This is a power-user feature. Configuration values are passed
+> directly to the model provider with minimal validation. Incorrect settings
+> (e.g., incompatible parameter combinations) may result in runtime errors from
+> the API.
+
+## 1. System Overview
+
+The Model Configuration system (`ModelConfigService`) enables deterministic
+control over model generation. It decouples the requested model identifier
+(e.g., a CLI flag or agent request) from the underlying API configuration. This
+allows for:
+
+- **Precise Hyperparameter Tuning**: Direct control over `temperature`, `topP`,
+  `thinkingBudget`, and other SDK-level parameters.
+- **Environment-Specific Behavior**: Distinct configurations for different
+  operating contexts (e.g., testing vs. production).
+- **Agent-Scoped Customization**: Applying specific settings only when a
+  particular agent is active.
+
+The system operates on two core primitives: **Aliases** and **Overrides**.
+
+## 2. Configuration Primitives
+
+These settings are located under the `modelConfigs` key in your configuration
+file.
+
+### Aliases (`customAliases`)
+
+Aliases are named, reusable configuration presets. Users should define their own
+aliases (or override system defaults) in the `customAliases` map.
+
+- **Inheritance**: An alias can `extends` another alias (including system
+  defaults like `chat-base`), inheriting its `modelConfig`. Child aliases can
+  overwrite or augment inherited settings.
+- **Abstract Aliases**: An alias is not required to specify a concrete `model`
+  if it serves purely as a base for other aliases.
+
+**Example Hierarchy**:
+
+```json
+"modelConfigs": {
+  "customAliases": {
+    "base": {
+      "modelConfig": {
+        "generateContentConfig": { "temperature": 0.0 }
+      }
+    },
+    "chat-base": {
+      "extends": "base",
+      "modelConfig": {
+        "generateContentConfig": { "temperature": 0.7 }
+      }
+    }
+  }
+}
+```
+
+### Overrides (`overrides`)
+
+Overrides are conditional rules that inject configuration based on the runtime
+context. They are evaluated dynamically for each model request.
+
+- **Match Criteria**: Overrides apply when the request context matches the
+  specified `match` properties.
+  - `model`: Matches the requested model name or alias.
+  - `overrideScope`: Matches the distinct scope of the request (typically the
+    agent name, e.g., `codebaseInvestigator`).
+
+**Example Override**:
+
+```json
+"modelConfigs": {
+  "overrides": [
+    {
+      "match": {
+        "overrideScope": "codebaseInvestigator"
+      },
+      "modelConfig": {

+    }
+  ]
+}
+```
+
+## 3. Resolution Strategy
+
+The `ModelConfigService` resolves the final configuration through a two-step
+process:
+
+### Step 1: Alias Resolution
+
+The requested model string is looked up in the merged map of system `aliases`
+and user `customAliases`.
+
+1.  If found, the system recursively resolves the `extends` chain.
+2.  Settings are merged from parent to child (child wins).
+3.  This results in a base `ResolvedModelConfig`.
+4.  If not found, the requested string is treated as the raw model name.
+
+### Step 2: Override Application
+
+The system evaluates the `overrides` list against the request context (`model`
+and `overrideScope`).
+
+1.  **Filtering**: All matching overrides are identified.
+2.  **Sorting**: Matches are prioritized by **specificity** (the number of
+    matched keys in the `match` object).
+    - Specific matches (e.g., `model` + `overrideScope`) override broad matches
+      (e.g., `model` only).
+    - Tie-breaking: If specificity is equal, the order of definition in the
+      `overrides` array is preserved (last one wins).
+3.  **Merging**: The configurations from the sorted overrides are merged
+    sequentially onto the base configuration.
+
+## 4. Configuration Reference
+
+The configuration follows the `ModelConfigServiceConfig` interface.
+
+### `ModelConfig` Object
+
+Defines the actual parameters for the model.
+
+| Property                | Type     | Description                                                        |
+| :---------------------- | :------- | :----------------------------------------------------------------- |
+| `model`                 | `string` | The identifier of the model to be called (e.g., `gemini-2.5-pro`). |
+| `generateContentConfig` | `object` | The configuration object passed to the `@google/genai` SDK.        |
+
+### `GenerateContentConfig` (Common Parameters)
+
+Directly maps to the SDK's `GenerateContentConfig`. Common parameters include:
+
+- **`temperature`**: (`number`) Controls output randomness. Lower values (0.0)
+  are deterministic; higher values (>0.7) are creative.
+- **`topP`**: (`number`) Nucleus sampling probability.
+- **`maxOutputTokens`**: (`number`) Limit on generated response length.
+- **`thinkingConfig`**: (`object`) Configuration for models with reasoning
+  capabilities (e.g., `thinkingBudget`, `includeThoughts`).
+
+## 5. Practical Examples
+
+### Defining a Deterministic Baseline
+
+Create an alias for tasks requiring high precision, extending the standard chat
+configuration but enforcing zero temperature.
+
+```json
+"modelConfigs": {
+  "customAliases": {
+    "precise-mode": {
+      "extends": "chat-base",
+      "modelConfig": {
+        "generateContentConfig": {
+          "temperature": 0.0,
+          "topP": 1.0
+        }
+      }
+    }
+  }
+}
+```
+
+### Agent-Specific Parameter Injection
+
+Enforce extended thinking budgets for a specific agent without altering the
+global default, e.g. for the `codebaseInvestigator`.
+
+```json
+"modelConfigs": {
+  "overrides": [
+    {
+      "match": {
+        "overrideScope": "codebaseInvestigator"
+      },
+      "modelConfig": {
+        "generateContentConfig": {
+          "thinkingConfig": { "thinkingBudget": 4096 }
+        }
+      }
+    }
+  ]
+}
+```
+
+### Experimental Model Evaluation
+
+Route traffic for a specific alias to a preview model for A/B testing, without
+changing client code.
+
+```json
+"modelConfigs": {
+  "overrides": [
+    {
+      "match": {
+        "model": "gemini-2.5-pro"
+      },
+      "modelConfig": {
+        "model": "gemini-2.5-pro-experimental-001"
+      }
+    }
+  ]
+}
+```

-## Model Routing
+# Model routing
 
 Gemini CLI includes a model routing feature that automatically switches to a
 fallback model in case of a model failure. This feature is enabled by default
 and provides resilience when the primary model is unavailable.
 
-## How it Works
+## How it works
 
-Model routing is not based on prompt complexity, but is a fallback mechanism.
-Here's how it works:
+Model routing is managed by the `ModelAvailabilityService`, which monitors model
+health and automatically routes requests to available models based on defined
+policies.
 
-1.  **Model Failure:** If the currently selected model fails to respond (for
-    example, due to a server error or other issue), the CLI will initiate the
-    fallback process.
+1.  **Model failure:** If the currently selected model fails (e.g., due to quota
+    or server errors), the CLI will initiate the fallback process.
 
-2.  **User Consent:** The CLI will prompt you to ask if you want to switch to
-    the fallback model. This is handled by the `fallbackModelHandler`.
+2.  **User consent:** Depending on the failure and the model's policy, the CLI
+    may prompt you to switch to a fallback model (by default always prompts
+    you).
 
-3.  **Fallback Activation:** If you consent, the CLI will activate the fallback
-    mode by calling `config.setFallbackMode(true)`.
+    Some internal utility calls (such as prompt completion and classification)
+    use a silent fallback chain for `gemini-2.5-flash-lite` and will fall back
+    to `gemini-2.5-flash` and `gemini-2.5-pro` without prompting or changing the
+    configured model.
 
-4.  **Model Switch:** On the next request, the CLI will use the
-    `DEFAULT_GEMINI_FLASH_MODEL` as the fallback model. This is handled by the
-    `resolveModel` function in
-    `packages/cli/src/zed-integration/zedIntegration.ts` which checks if
-    `isInFallbackMode()` is true.
+3.  **Model switch:** If approved, or if the policy allows for silent fallback,
+    the CLI will use an available fallback model for the current turn or the
+    remainder of the session.
 
-## Configuration
-
-Model routing is controlled by the `useModelRouter` setting in your
-`settings.json` file.
-
-- **`"experimental.useModelRouter": true` (Default):** Enables the model
-  routing/fallback feature.
-
-- **`"experimental.useModelRouter": false`:** Disables the model
-  routing/fallback feature. If a model fails, the CLI will not attempt to switch
-  to a fallback model.

+# Rewind
+
+The `/rewind` command allows you to go back to a previous state in your
+conversation and, optionally, revert any file changes made by the AI during
+those interactions. This is a powerful tool for undoing mistakes, exploring
+different approaches, or simply cleaning up your session history.
+
+## Usage
+
+To use the rewind feature, simply type `/rewind` into the input prompt and press
+**Enter**.
+
+Alternatively, you can use the keyboard shortcut: **Press `Esc` twice**.
+
+## Interface
+
+When you trigger a rewind, an interactive list of your previous interactions
+appears.
+
+1.  **Select Interaction:** Use the **Up/Down arrow keys** to navigate through
+    the list. The most recent interactions are at the bottom.
+2.  **Preview:** As you select an interaction, you'll see a preview of the user
+    prompt and, if applicable, the number of files changed during that step.
+3.  **Confirm Selection:** Press **Enter** on the interaction you want to rewind
+    back to.
+4.  **Action Selection:** After selecting an interaction, you'll be presented
+    with a confirmation dialog with up to three options:
+    - **Rewind conversation and revert code changes:** Reverts both the chat
+      history and the file modifications to the state before the selected
+      interaction.
+    - **Rewind conversation:** Only reverts the chat history. File changes are
+      kept.
+    - **Revert code changes:** Only reverts the file modifications. The chat
+      history is kept.
+    - **Do nothing (esc):** Cancels the rewind operation.
+
+If no code changes were made since the selected point, the options related to
+reverting code changes will be hidden.
+
+## Key Considerations
+
+- **Destructive Action:** Rewinding is a destructive action for your current
+  session history and potentially your files. Use it with care.
+- **Agent Awareness:** When you rewind the conversation, the AI model loses all
+  memory of the interactions that were removed. If you only revert code changes,
+  you may need to inform the model that the files have changed.
+- **Manual Edits:** Rewinding only affects file changes made by the AI's edit
+  tools. It does **not** undo manual edits you've made or changes triggered by
+  the shell tool (`!`).
+- **Compression:** Rewind works across chat compression points by reconstructing
+  the history from stored session data.

+# Session Management
+
+Gemini CLI includes robust session management features that automatically save
+your conversation history. This allows you to interrupt your work and resume
+exactly where you left off, review past interactions, and manage your
+conversation history effectively.
+
+## Automatic Saving
+
+Every time you interact with Gemini CLI, your session is automatically saved.
+This happens in the background without any manual intervention.
+
+- **What is saved:** The complete conversation history, including:
+  - Your prompts and the model's responses.
+  - All tool executions (inputs and outputs).
+  - Token usage statistics (input/output/cached, etc.).
+  - Assistant thoughts/reasoning summaries (when available).
+- **Location:** Sessions are stored in `~/.gemini/tmp/<project_hash>/chats/`.
+- **Scope:** Sessions are project-specific. Switching directories to a different
+  project will switch to that project's session history.
+
+## Resuming Sessions
+
+You can resume a previous session to continue the conversation with all prior
+context restored.
+
+### From the Command Line
+
+When starting the CLI, you can use the `--resume` (or `-r`) flag:
+
+- **Resume latest:**
+
+  ```bash
+  gemini --resume
+  ```
+
+  This immediately loads the most recent session.
+
+- **Resume by index:** First, list available sessions (see
+  [Listing Sessions](#listing-sessions)), then use the index number:

+  gemini --resume 1

+- **Resume by ID:** You can also provide the full session UUID:
+  ```bash
+  gemini --resume a1b2c3d4-e5f6-7890-abcd-ef1234567890
+  ```
+
+### From the Interactive Interface
+
+While the CLI is running, you can use the `/resume` slash command to open the
+**Session Browser**:
+
+```text
+/resume
+```
+
+This opens an interactive interface where you can:
+
+- **Browse:** Scroll through a list of your past sessions.
+- **Preview:** See details like the session date, message count, and the first
+  user prompt.
+- **Search:** Press `/` to enter search mode, then type to filter sessions by ID
+  or content.
+- **Select:** Press `Enter` to resume the selected session.
+
+## Managing Sessions
+
+### Listing Sessions
+
+To see a list of all available sessions for the current project from the command
+line:
+
+```bash
+gemini --list-sessions
+```
+
+Output example:
+
+```text
+Available sessions for this project (3):
+
+  1. Fix bug in auth (2 days ago) [a1b2c3d4]
+  2. Refactor database schema (5 hours ago) [e5f67890]
+  3. Update documentation (Just now) [abcd1234]
+```
+
+### Deleting Sessions
+
+You can remove old or unwanted sessions to free up space or declutter your
+history.
+
+**From the Command Line:** Use the `--delete-session` flag with an index or ID:
+
+```bash
+gemini --delete-session 2
+```
+
+**From the Session Browser:**
+
+1.  Open the browser with `/resume`.
+2.  Navigate to the session you want to remove.
+3.  Press `x`.
+
+## Configuration
+
+You can configure how Gemini CLI manages your session history in your
+`settings.json` file.
+
+### Session Retention
+
+To prevent your history from growing indefinitely, you can enable automatic
+cleanup policies.
+
+```json
+{
+  "general": {
+    "sessionRetention": {
+      "enabled": true,
+      "maxAge": "30d", // Keep sessions for 30 days
+      "maxCount": 50 // Keep the 50 most recent sessions
+    }
+  }
+}
+```
+
+- **`enabled`**: (boolean) Master switch for session cleanup. Default is
+  `false`.
+- **`maxAge`**: (string) Duration to keep sessions (e.g., "24h", "7d", "4w").
+  Sessions older than this will be deleted.
+- **`maxCount`**: (number) Maximum number of sessions to retain. The oldest
+  sessions exceeding this count will be deleted.
+- **`minRetention`**: (string) Minimum retention period (safety limit). Defaults
+  to `"1d"`; sessions newer than this period are never deleted by automatic
+  cleanup.
+
+### Session Limits
+
+You can also limit the length of individual sessions to prevent context windows
+from becoming too large and expensive.
+
+```json
+{
+  "model": {
+    "maxSessionTurns": 100
+  }
+}
+```
+
+- **`maxSessionTurns`**: (number) The maximum number of turns (user + model
+  exchanges) allowed in a single session. Set to `-1` for unlimited (default).
+
+  **Behavior when limit is reached:**
+  - **Interactive Mode:** The CLI shows an informational message and stops
+    sending requests to the model. You must manually start a new session.
+  - **Non-Interactive Mode:** The CLI exits with an error.

+# Agent Skills
+
+Agent Skills allow you to extend Gemini CLI with specialized expertise,
+procedural workflows, and task-specific resources. Based on the
+[Agent Skills](https://agentskills.io) open standard, a "skill" is a
+self-contained directory that packages instructions and assets into a
+discoverable capability.
+
+## Overview
+
+Unlike general context files ([`GEMINI.md`](./gemini-md.md)), which provide
+persistent workspace-wide background, Skills represent **on-demand expertise**.
+This allows Gemini to maintain a vast library of specialized capabilities—such
+as security auditing, cloud deployments, or codebase migrations—without
+cluttering the model's immediate context window.
+
+Gemini autonomously decides when to employ a skill based on your request and the
+skill's description. When a relevant skill is identified, the model "pulls in"
+the full instructions and resources required to complete the task using the
+`activate_skill` tool.
+
+## Key Benefits
+
+- **Shared Expertise:** Package complex workflows (like a specific team's PR
+  review process) into a folder that anyone can use.
+- **Repeatable Workflows:** Ensure complex multi-step tasks are performed
+  consistently by providing a procedural framework.
+- **Resource Bundling:** Include scripts, templates, or example data alongside
+  instructions so the agent has everything it needs.
+- **Progressive Disclosure:** Only skill metadata (name and description) is
+  loaded initially. Detailed instructions and resources are only disclosed when
+  the model explicitly activates the skill, saving context tokens.
+
+## Skill Discovery Tiers
+
+Gemini CLI discovers skills from three primary locations:
+
+1.  **Workspace Skills** (`.gemini/skills/`): Workspace-specific skills that are
+    typically committed to version control and shared with the team.
+2.  **User Skills** (`~/.gemini/skills/`): Personal skills available across all
+    your workspaces.
+3.  **Extension Skills**: Skills bundled within installed
+    [extensions](../extensions/index.md).
+
+**Precedence:** If multiple skills share the same name, higher-precedence
+locations override lower ones: **Workspace > User > Extension**.
+
+## Managing Skills
+
+### In an Interactive Session
+
+Use the `/skills` slash command to view and manage available expertise:
+
+- `/skills list` (default): Shows all discovered skills and their status.
+- `/skills link <path>`: Links agent skills from a local directory via symlink.
+- `/skills disable <name>`: Prevents a specific skill from being used.
+- `/skills enable <name>`: Re-enables a disabled skill.
+- `/skills reload`: Refreshes the list of discovered skills from all tiers.
+
+_Note: `/skills disable` and `/skills enable` default to the `user` scope. Use
+`--scope workspace` to manage workspace-specific settings._
+
+### From the Terminal
+
+The `gemini skills` command provides management utilities:
+
+```bash
+# List all discovered skills
+gemini skills list
+
+# Link agent skills from a local directory via symlink
+# Discovers skills (SKILL.md or */SKILL.md) and creates symlinks in ~/.gemini/skills (user)
+gemini skills link /path/to/my-skills-repo
+
+# Link to the workspace scope (.gemini/skills)
+gemini skills link /path/to/my-skills-repo --scope workspace
+
+# Install a skill from a Git repository, local directory, or zipped skill file (.skill)
+# Uses the user scope by default (~/.gemini/skills)
+gemini skills install https://github.com/user/repo.git
+gemini skills install /path/to/local/skill
+gemini skills install /path/to/local/my-expertise.skill
+
+# Install a specific skill from a monorepo or subdirectory using --path
+gemini skills install https://github.com/my-org/my-skills.git --path skills/frontend-design
+
+# Install to the workspace scope (.gemini/skills)
+gemini skills install /path/to/skill --scope workspace
+
+# Uninstall a skill by name
+gemini skills uninstall my-expertise --scope workspace
+
+# Enable a skill (globally)
+gemini skills enable my-expertise
+
+# Disable a skill. Can use --scope to specify workspace or user (defaults to workspace)
+gemini skills disable my-expertise --scope workspace
+```
+
+## How it Works
+
+1.  **Discovery**: At the start of a session, Gemini CLI scans the discovery
+    tiers and injects the name and description of all enabled skills into the
+    system prompt.
+2.  **Activation**: When Gemini identifies a task matching a skill's
+    description, it calls the `activate_skill` tool.
+3.  **Consent**: You will see a confirmation prompt in the UI detailing the
+    skill's name, purpose, and the directory path it will gain access to.
+4.  **Injection**: Upon your approval:
+    - The `SKILL.md` body and folder structure is added to the conversation
+      history.
+    - The skill's directory is added to the agent's allowed file paths, granting
+      it permission to read any bundled assets.
+5.  **Execution**: The model proceeds with the specialized expertise active. It
+    is instructed to prioritize the skill's procedural guidance within reason.
+
+### Skill activation
+
+Once a skill is activated (typically by Gemini identifying a task that matches
+the skill's description and your approval), its specialized instructions and
+resources are loaded into the agent's context. A skill remains active and its
+guidance is prioritized for the duration of the session.

+# System Prompt Override (GEMINI_SYSTEM_MD)
+
+The core system instructions that guide Gemini CLI can be completely replaced
+with your own Markdown file. This feature is controlled via the
+`GEMINI_SYSTEM_MD` environment variable.
+
+## Overview
+
+The `GEMINI_SYSTEM_MD` variable instructs the CLI to use an external Markdown
+file for its system prompt, completely overriding the built-in default. This is
+a full replacement, not a merge. If you use a custom file, none of the original
+core instructions will apply unless you include them yourself.
+
+This feature is intended for advanced users who need to enforce strict,
+project-specific behavior or create a customized persona.
+
+> Tip: You can export the current default system prompt to a file first, review
+> it, and then selectively modify or replace it (see
+> [“Export the default prompt”](#export-the-default-prompt-recommended)).
+
+## How to enable
+
+You can set the environment variable temporarily in your shell, or persist it
+via a `.gemini/.env` file. See
+[Persisting Environment Variables](../get-started/authentication.md#persisting-environment-variables).
+
+- Use the project default path (`.gemini/system.md`):
+  - `GEMINI_SYSTEM_MD=true` or `GEMINI_SYSTEM_MD=1`
+  - The CLI reads `./.gemini/system.md` (relative to your current project
+    directory).
+
+- Use a custom file path:
+  - `GEMINI_SYSTEM_MD=/absolute/path/to/my-system.md`
+  - Relative paths are supported and resolved from the current working
+    directory.
+  - Tilde expansion is supported (e.g., `~/my-system.md`).
+
+- Disable the override (use built‑in prompt):
+  - `GEMINI_SYSTEM_MD=false` or `GEMINI_SYSTEM_MD=0` or unset the variable.
+
+If the override is enabled but the target file does not exist, the CLI will
+error with: `missing system prompt file '<path>'`.
+
+## Quick examples
+
+- One‑off session using a project file:
+  - `GEMINI_SYSTEM_MD=1 gemini`
+- Persist for a project using `.gemini/.env`:
+  - Create `.gemini/system.md`, then add to `.gemini/.env`:
+    - `GEMINI_SYSTEM_MD=1`
+- Use a custom file under your home directory:
+  - `GEMINI_SYSTEM_MD=~/prompts/SYSTEM.md gemini`
+
+## UI indicator
+
+When `GEMINI_SYSTEM_MD` is active, the CLI shows a `|⌐■_■|` indicator in the UI
+to signal custom system‑prompt mode.
+
+## Variable Substitution
+
+When using a custom system prompt file, you can use the following variables to
+dynamically include built-in content:
+
+- `${AgentSkills}`: Injects a complete section (including header) of all
+  available agent skills.
+- `${SubAgents}`: Injects a complete section (including header) of available
+  sub-agents.
+- `${AvailableTools}`: Injects a bulleted list of all currently enabled tool
+  names.
+- Tool Name Variables: Injects the actual name of a tool using the pattern:
+  `${toolName}_ToolName` (e.g., `${write_file_ToolName}`,
+  `${run_shell_command_ToolName}`).
+
+  This pattern is generated dynamically for all available tools.
+
+### Example
+
+```markdown
+# Custom System Prompt
+
+You are a helpful assistant. ${AgentSkills}
+${SubAgents}
+
+## Tooling
+
+The following tools are available to you: ${AvailableTools}
+
+You can use ${write_file_ToolName} to save logs.
+```
+
+## Export the default prompt (recommended)
+
+Before overriding, export the current default prompt so you can review required
+safety and workflow rules.
+
+- Write the built‑in prompt to the project default path:
+  - `GEMINI_WRITE_SYSTEM_MD=1 gemini`
+- Or write to a custom path:
+  - `GEMINI_WRITE_SYSTEM_MD=~/prompts/DEFAULT_SYSTEM.md gemini`
+
+This creates the file and writes the current built‑in system prompt to it.
+
+## Best practices: SYSTEM.md vs GEMINI.md
+
+- SYSTEM.md (firmware):
+  - Non‑negotiable operational rules: safety, tool‑use protocols, approvals, and
+    mechanics that keep the CLI reliable.
+  - Stable across tasks and projects (or per project when needed).
+- GEMINI.md (strategy):
+  - Persona, goals, methodologies, and project/domain context.
+  - Evolves per task; relies on SYSTEM.md for safe execution.
+
+Keep SYSTEM.md minimal but complete for safety and tool operation. Keep
+GEMINI.md focused on high‑level guidance and project specifics.
+
+## Troubleshooting
+
+- Error: `missing system prompt file '…'`
+  - Ensure the referenced path exists and is readable.
+  - For `GEMINI_SYSTEM_MD=1|true`, create `./.gemini/system.md` in your project.
+- Override not taking effect
+  - Confirm the variable is loaded (use `.gemini/.env` or export in your shell).
+  - Paths are resolved from the current working directory; try an absolute path.
+- Restore defaults
+  - Unset `GEMINI_SYSTEM_MD` or set it to `0`/`false`.

+# Getting Started with Agent Skills
+
+Agent Skills allow you to extend Gemini CLI with specialized expertise. This
+tutorial will guide you through creating your first skill and using it in a
+session.
+
+## 1. Create your first skill
+
+A skill is a directory containing a `SKILL.md` file. Let's create an **API
+Auditor** skill that helps you verify if local or remote endpoints are
+responding correctly.
+
+1.  **Create the skill directory structure:**
+
+    ```bash
+    mkdir -p .gemini/skills/api-auditor/scripts
+    ```
+
+2.  **Create the `SKILL.md` file:** Create a file at
+    `.gemini/skills/api-auditor/SKILL.md` with the following content:
+
+    ```markdown
+    ---
+    name: api-auditor
+    description:
+      Expertise in auditing and testing API endpoints. Use when the user asks to
+      "check", "test", or "audit" a URL or API.
+    ---
+
+    # API Auditor Instructions
+
+    You act as a QA engineer specialized in API reliability. When this skill is
+    active, you MUST:
+
+    1.  **Audit**: Use the bundled `scripts/audit.js` utility to check the
+        status of the provided URL.
+    2.  **Report**: Analyze the output (status codes, latency) and explain any
+        failures in plain English.
+    3.  **Secure**: Remind the user if they are testing a sensitive endpoint
+        without an `https://` protocol.
+    ```
+
+3.  **Create the bundled Node.js script:** Create a file at
+    `.gemini/skills/api-auditor/scripts/audit.js`. This script will be used by
+    the agent to perform the actual check:
+
+    ```javascript
+    // .gemini/skills/api-auditor/scripts/audit.js
+    const url = process.argv[2];
+
+    if (!url) {
+      console.error('Usage: node audit.js <url>');
+      process.exit(1);
+    }
+
+    console.log(`Auditing ${url}...`);
+    fetch(url, { method: 'HEAD' })
+      .then((r) => console.log(`Result: Success (Status ${r.status})`))
+      .catch((e) => console.error(`Result: Failed (${e.message})`));
+    ```
+
+## 2. Verify the skill is discovered
+
+Use the `/skills` slash command (or `gemini skills list` from your terminal) to
+see if Gemini CLI has found your new skill.
+
+In a Gemini CLI session:
+
+```
+/skills list
+```
+
+You should see `api-auditor` in the list of available skills.
+
+## 3. Use the skill in a chat
+
+Now, let's see the skill in action. Start a new session and ask a question about
+an endpoint.
+
+**User:** "Can you audit http://geminili.com"
+
+Gemini will recognize the request matches the `api-auditor` description and will
+ask for your permission to activate it.
+
+**Model:** (After calling `activate_skill`) "I've activated the **api-auditor**
+skill. I'll run the audit script now..."
+
+Gemini will then use the `run_shell_command` tool to execute your bundled Node
+script:
+
+`node .gemini/skills/api-auditor/scripts/audit.js http://geminili.com`

 confirmation.

+    commandPrefix = "git status"

+# Remote Subagents (experimental)
+
+Gemini CLI supports connecting to remote subagents using the Agent-to-Agent
+(A2A) protocol. This allows Gemini CLI to interact with other agents, expanding
+its capabilities by delegating tasks to remote services.
+
+Gemini CLI can connect to any compliant A2A agent. You can find samples of A2A
+agents in the following repositories:
+
+- [ADK Samples (Python)](https://github.com/google/adk-samples/tree/main/python)

+
+## Configuration
+
+To use remote subagents, you must explicitly enable them in your
+`settings.json`:
+
+```json
+{
+  "experimental": {
+    "enableAgents": true
+  }
+}
+```
+
+## Defining remote subagents
+

+# Sub-agents (experimental)
+
+Sub-agents are specialized agents that operate within your main Gemini CLI
+session. They are designed to handle specific, complex tasks—like deep codebase
+analysis, documentation lookup, or domain-specific reasoning—without cluttering
+the main agent's context or toolset.
+
+> **Note: Sub-agents are currently an experimental feature.**
+>
+> To use custom sub-agents, you must explicitly enable them in your
+> `settings.json`:
+>
+> ```json
+> {
+>   "experimental": { "enableAgents": true }
+> }
+> ```
+>
+> **Warning:** Sub-agents currently operate in
+> ["YOLO mode"](../get-started/configuration.md#command-line-arguments), meaning
+> they may execute tools without individual user confirmation for each step.
+> Proceed with caution when defining agents with powerful tools like
+> `run_shell_command` or `write_file`.
+
+## What are sub-agents?
+
+Sub-agents are "specialists" that the main Gemini agent can hire for a specific
+job.
+
+- **Focused context:** Each sub-agent has its own system prompt and persona.
+- **Specialized tools:** Sub-agents can have a restricted or specialized set of
+  tools.
+- **Independent context window:** Interactions with a sub-agent happen in a
+  separate context loop, which saves tokens in your main conversation history.
+
+Sub-agents are exposed to the main agent as a tool of the same name. When the
+main agent calls the tool, it delegates the task to the sub-agent. Once the
+sub-agent completes its task, it reports back to the main agent with its
+findings.
+
+## Built-in sub-agents
+
+Gemini CLI comes with the following built-in sub-agents:
+
+### Codebase Investigator
+
+- **Name:** `codebase_investigator`
+- **Purpose:** Analyze the codebase, reverse engineer, and understand complex
+  dependencies.
+- **When to use:** "How does the authentication system work?", "Map out the
+  dependencies of the `AgentRegistry` class."
+- **Configuration:** Enabled by default. You can configure it in
+  `settings.json`. Example (forcing a specific model):
+  ```json
+  {
+    "experimental": {
+      "codebaseInvestigatorSettings": {
+        "enabled": true,
+        "maxNumTurns": 20,
+        "model": "gemini-2.5-pro"
+      }
+    }
+  }
+  ```
+
+### CLI Help Agent
+
+- **Name:** `cli_help`
+- **Purpose:** Get expert knowledge about Gemini CLI itself, its commands,
+  configuration, and documentation.
+- **When to use:** "How do I configure a proxy?", "What does the `/rewind`
+  command do?"
+- **Configuration:** Enabled by default.
+
+### Generalist Agent
+
+- **Name:** `generalist_agent`
+- **Purpose:** Route tasks to the appropriate specialized sub-agent.
+- **When to use:** Implicitly used by the main agent for routing. Not directly
+  invoked by the user.
+- **Configuration:** Enabled by default. No specific configuration options.
+
+## Creating custom sub-agents
+
+You can create your own sub-agents to automate specific workflows or enforce
+specific personas. To use custom sub-agents, you must enable them in your
+`settings.json`:
+
+```json
+{
+  "experimental": {
+    "enableAgents": true
+  }
+}
+```
+
+### Agent definition files
+
+Custom agents are defined as Markdown files (`.md`) with YAML frontmatter. You
+can place them in:
+
+1.  **Project-level:** `.gemini/agents/*.md` (Shared with your team)
+2.  **User-level:** `~/.gemini/agents/*.md` (Personal agents)
+
+### File format
+
+The file **MUST** start with YAML frontmatter enclosed in triple-dashes `---`.
+The body of the markdown file becomes the agent's **System Prompt**.
+
+**Example: `.gemini/agents/security-auditor.md`**
+
+```markdown
+---
+name: security-auditor
+description: Specialized in finding security vulnerabilities in code.
+kind: local
+tools:
+  - read_file
+  - grep_search
+model: gemini-2.5-pro
+temperature: 0.2
+max_turns: 10

+
+You are a ruthless Security Auditor. Your job is to analyze code for potential
+vulnerabilities.
+
+Focus on:
+
+1.  SQL Injection
+2.  XSS (Cross-Site Scripting)
+3.  Hardcoded credentials
+4.  Unsafe file operations
+
+When you find a vulnerability, explain it clearly and suggest a fix. Do not fix
+it yourself; just report it.

+| `model`        | string | No       | Specific model to use (e.g., `gemini-2.5-pro`). Defaults to `inherit` (uses the main session model).                       |
+| `temperature`  | number | No       | Model temperature (0.0 - 2.0).                                                                                             |
+| `max_turns`    | number | No       | Maximum number of conversation turns allowed for this agent before it must return. Defaults to `15`.                       |
+| `timeout_mins` | number | No       | Maximum execution time in minutes. Defaults to `5`.                                                                        |
+
+### Optimizing your sub-agent
+
+The main agent's system prompt encourages it to use an expert sub-agent when one
+is available. It decides whether an agent is a relevant expert based on the
+agent's description. You can improve the reliability with which an agent is used
+by updating the description to more clearly indicate:
+
+- Its area of expertise.
+- When it should be used.
+- Some example scenarios.
+
+For example, the following sub-agent description should be called fairly
+consistently for Git operations.
+
+> Git expert agent which should be used for all local and remote git operations.
+> For example:
+>
+> - Making commits
+> - Searching for regressions with bisect
+> - Interacting with source control and issues providers such as GitHub.
+
+If you need to further tune your sub-agent, you can do so by selecting the model
+to optimize for with `/model` and then asking the model why it does not think
+that your sub-agent was called with a specific prompt and the given description.
+
+## Remote subagents (Agent2Agent) (experimental)
+
+Gemini CLI can also delegate tasks to remote sub-agents using the Agent-to-Agent
+(A2A) protocol.
+
+> **Note: Remote subagents are currently an experimental feature.**
+
+See the [Remote Subagents documentation](/docs/core/remote-agents) for detailed
+configuration and usage instructions.
+
+## Extension sub-agents
+
+Extensions can bundle and distribute sub-agents. See the
+[Extensions documentation](../extensions/index.md#sub-agents) for details on how
+to package agents within an extension.

+# Extensions on Gemini CLI: Best practices
+
+This guide covers best practices for developing, securing, and maintaining
+Gemini CLI extensions.
+
+## Development
+
+Developing extensions for Gemini CLI is intended to be a lightweight, iterative
+process.
+
+### Structure your extension
+
+While simple extensions can just be a few files, we recommend a robust structure
+for complex extensions:
+
+```
+my-extension/
+├── package.json
+├── tsconfig.json
+├── gemini-extension.json
+├── src/
+│   ├── index.ts
+│   └── tools/
+└── dist/
+```
+
+- **Use TypeScript**: We strongly recommend using TypeScript for type safety and
+  better tooling.
+- **Separate source and build**: Keep your source code in `src` and build to
+  `dist`.
+- **Bundle dependencies**: If your extension has many dependencies, consider
+  bundling them (e.g., with `esbuild` or `webpack`) to reduce install time and
+  potential conflicts.
+
+### Iterate with `link`
+
+Use `gemini extensions link` to develop locally without constantly reinstalling:
+
+```bash
+cd my-extension
+gemini extensions link .
+```
+
+Changes to your code (after rebuilding) will be immediately available in the CLI
+on restart.
+
+### Use `GEMINI.md` effectively
+
+Your `GEMINI.md` file provides context to the model. Keep it focused:
+
+- **Do:** Explain high-level goals and how to use the provided tools.
+- **Don't:** Dump your entire documentation.
+- **Do:** Use clear, concise language.
+
+## Security
+
+When building a Gemini CLI extension, follow general security best practices
+(such as least privilege and input validation) to reduce risk.
+
+### Minimal permissions
+
+When defining tools in your MCP server, only request the permissions necessary.
+Avoid giving the model broad access (like full shell access) if a more
+restricted set of tools will suffice.
+
+If you must use powerful tools like `run_shell_command`, consider restricting
+them to specific commands in your `gemini-extension.json`:
+
+```json
+{
+  "name": "my-safe-extension",
+  "excludeTools": ["run_shell_command(rm -rf *)"]
+}
+```
+
+This ensures that even if the model tries to execute a dangerous command, it
+will be blocked at the CLI level.
+
+### Validate inputs
+
+Your MCP server is running on the user's machine. Always validate inputs to your
+tools to prevent arbitrary code execution or filesystem access outside the
+intended scope.
+
+```typescript
+// Good: Validating paths
+if (!path.resolve(inputPath).startsWith(path.resolve(allowedDir) + path.sep)) {
+  throw new Error('Access denied');
+}
+```
+
+### Sensitive settings
+
+If your extension requires API keys, use the `sensitive: true` option in
+`gemini-extension.json`. This ensures keys are stored securely in the system
+keychain and obfuscated in the UI.
+
+```json
+"settings": [
+  {
+    "name": "API Key",
+    "envVar": "MY_API_KEY",
+    "sensitive": true
+  }
+]
+```
+
+## Releasing
+
+You can upload your extension directly to GitHub to list it in the gallery.
+Gemini CLI extensions also offers support for more complicated
+[releases](releasing.md).
+
+### Semantic versioning
+
+Follow [Semantic Versioning](https://semver.org/).
+
+- **Major**: Breaking changes (renaming tools, changing arguments).
+- **Minor**: New features (new tools, commands).
+- **Patch**: Bug fixes.
+
+### Release Channels
+
+Use git branches to manage release channels (e.g., `main` for stable, `dev` for
+bleeding edge). This allows users to choose their stability level:
+
+```bash
+# Stable
+gemini extensions install github.com/user/repo
+
+# Dev
+gemini extensions install github.com/user/repo --ref dev
+```
+
+### Clean artifacts
+
+If you are using GitHub Releases, ensure your release artifacts only contain the
+necessary files (`dist/`, `gemini-extension.json`, `package.json`). Exclude
+`node_modules` (users will install them) and `src/` to keep downloads small.

+Gemini CLI extensions package prompts, MCP servers, custom commands, hooks,
+sub-agents, and agent skills into a familiar and user-friendly format. With
+extensions, you can expand the capabilities of Gemini CLI and share those
+capabilities with others. They are designed to be easily installable and
+shareable.
 
 To see examples of extensions, you can browse a gallery of
 [Gemini CLI extensions](https://geminicli.com/extensions/browse/).
 
-See [getting started docs](getting-started-extensions.md) for a guide on
-creating your first extension.
+## Managing extensions
 
-See [releasing docs](extension-releasing.md) for an advanced guide on setting up
-GitHub releases.
+You can verify your installed extensions and their status using the interactive
+command:
 
-## Extension management
-
-We offer a suite of extension management tools using `gemini extensions`
-commands.
-
-Note that these commands are not supported from within the CLI, although you can
-list installed extensions using the `/extensions list` subcommand.
-
-Note that all of these commands will only be reflected in active CLI sessions on
-restart.
-
-### Installing an extension
-
-You can install an extension using `gemini extensions install` with either a
-GitHub URL or a local path.
-
-Note that we create a copy of the installed extension, so you will need to run
-`gemini extensions update` to pull in changes from both locally-defined
-extensions and those on GitHub.
-
-NOTE: If you are installing an extension from GitHub, you'll need to have `git`
-installed on your machine. See
-[git installation instructions](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
-for help.
-
-```
-gemini extensions install <source> [--ref <ref>] [--auto-update] [--pre-release] [--consent]
+```bash
+/extensions list
 ```
 
-- `<source>`: The github URL or local path of the extension to install.
-- `--ref`: The git ref to install from.
-- `--auto-update`: Enable auto-update for this extension.
-- `--pre-release`: Enable pre-release versions for this extension.
-- `--consent`: Acknowledge the security risks of installing an extension and
-  skip the confirmation prompt.
+or in noninteractive mode:
 
-### Uninstalling an extension
-
-To uninstall, run `gemini extensions uninstall <name>`:
-
-```
-gemini extensions uninstall gemini-cli-security
+```bash
+gemini extensions list
 ```
 
-### Disabling an extension
+## Installation
 
-Extensions are, by default, enabled across all workspaces. You can disable an
-extension entirely or for specific workspace.
+To install a real extension, you can use the `extensions install` command with a
+GitHub repository URL in noninteractive mode. For example:
 
-```
-gemini extensions disable <name> [--scope <scope>]
+```bash
+gemini extensions install https://github.com/gemini-cli-extensions/workspace
 ```
 
-- `<name>`: The name of the extension to disable.
-- `--scope`: The scope to disable the extension in (`user` or `workspace`).
+## Next steps
 
-### Enabling an extension
-
-You can enable extensions using `gemini extensions enable <name>`. You can also
-enable an extension for a specific workspace using
-`gemini extensions enable <name> --scope=workspace` from within that workspace.
-
-```
-gemini extensions enable <name> [--scope <scope>]
-```
-
-- `<name>`: The name of the extension to enable.
-- `--scope`: The scope to enable the extension in (`user` or `workspace`).
-
-### Updating an extension
-
-For extensions installed from a local path or a git repository, you can
-explicitly update to the latest version (as reflected in the
-`gemini-extension.json` `version` field) with `gemini extensions update <name>`.
-
-You can update all extensions with:
-
-```
-gemini extensions update --all
-```
-
-### Create a boilerplate extension
-
-We offer several example extensions `context`, `custom-commands`,
-`exclude-tools` and `mcp-server`. You can view these examples
-[here](https://github.com/google-gemini/gemini-cli/tree/main/packages/cli/src/commands/extensions/examples).
-
-To copy one of these examples into a development directory using the type of
-your choosing, run:
-
-```
-gemini extensions new <path> [template]
-```
-
-- `<path>`: The path to create the extension in.
-- `[template]`: The boilerplate template to use.
-
-### Link a local extension
-
-The `gemini extensions link` command will create a symbolic link from the
-extension installation directory to the development path.
-
-This is useful so you don't have to run `gemini extensions update` every time
-you make changes you'd like to test.
-
-```
-gemini extensions link <path>
-```
-
-- `<path>`: The path of the extension to link.
-
-## How it works
-
-On startup, Gemini CLI looks for extensions in `<home>/.gemini/extensions`
-
-Extensions exist as a directory that contains a `gemini-extension.json` file.
-For example:
-
-`<home>/.gemini/extensions/my-extension/gemini-extension.json`
-
-### `gemini-extension.json`
-
-The `gemini-extension.json` file contains the configuration for the extension.
-The file has the following structure:
-
-```json
-{
-  "name": "my-extension",
-  "version": "1.0.0",
-  "mcpServers": {
-    "my-server": {
-      "command": "node my-server.js"
-    }
-  },
-  "contextFileName": "GEMINI.md",
-  "excludeTools": ["run_shell_command"]
-}
-```
-
-- `name`: The name of the extension. This is used to uniquely identify the
-  extension and for conflict resolution when extension commands have the same
-  name as user or project commands. The name should be lowercase or numbers and
-  use dashes instead of underscores or spaces. This is how users will refer to
-  your extension in the CLI. Note that we expect this name to match the
-  extension directory name.
-- `version`: The version of the extension.
-- `mcpServers`: A map of MCP servers to configure. The key is the name of the
-  server, and the value is the server configuration. These servers will be
-  loaded on startup just like MCP servers configured in a
-  [`settings.json` file](../get-started/configuration.md). If both an extension
-  and a `settings.json` file configure an MCP server with the same name, the
-  server defined in the `settings.json` file takes precedence.
-  - Note that all MCP server configuration options are supported except for
-    `trust`.
-- `contextFileName`: The name of the file that contains the context for the
-  extension. This will be used to load the context from the extension directory.
-  If this property is not used but a `GEMINI.md` file is present in your
-  extension directory, then that file will be loaded.
-- `excludeTools`: An array of tool names to exclude from the model. You can also
-  specify command-specific restrictions for tools that support it, like the
-  `run_shell_command` tool. For example,
-  `"excludeTools": ["run_shell_command(rm -rf)"]` will block the `rm -rf`
-  command. Note that this differs from the MCP server `excludeTools`
-  functionality, which can be listed in the MCP server config.
-
-When Gemini CLI starts, it loads all the extensions and merges their
-configurations. If there are any conflicts, the workspace configuration takes
-precedence.
-
-### Settings
-
-_Note: This is an experimental feature. We do not yet recommend extension
-authors introduce settings as part of their core flows._
-
-Extensions can define settings that the user will be prompted to provide upon
-installation. This is useful for things like API keys, URLs, or other
-configuration that the extension needs to function.
-
-To define settings, add a `settings` array to your `gemini-extension.json` file.
-Each object in the array should have the following properties:
-
-- `name`: A user-friendly name for the setting.
-- `description`: A description of the setting and what it's used for.
-- `envVar`: The name of the environment variable that the setting will be stored
-  as.
-- `sensitive`: Optional boolean. If true, obfuscates the input the user provides
-  and stores the secret in keychain storage. **Example**
-
-```json
-{
-  "name": "my-api-extension",
-  "version": "1.0.0",
-  "settings": [
-    {
-      "name": "API Key",
-      "description": "Your API key for the service.",
-      "envVar": "MY_API_KEY"
-    }
-  ]
-}
-```
-
-When a user installs this extension, they will be prompted to enter their API
-key. The value will be saved to a `.env` file in the extension's directory
-(e.g., `<home>/.gemini/extensions/my-api-extension/.env`).
-
-### Custom commands
-
-Extensions can provide [custom commands](../cli/custom-commands.md) by placing
-TOML files in a `commands/` subdirectory within the extension directory. These
-commands follow the same format as user and project custom commands and use
-standard naming conventions.
-
-**Example**
-
-An extension named `gcp` with the following structure:
-
-```
-.gemini/extensions/gcp/
-├── gemini-extension.json
-└── commands/
-    ├── deploy.toml
-    └── gcs/
-        └── sync.toml
-```
-
-Would provide these commands:
-
-- `/deploy` - Shows as `[gcp] Custom command from deploy.toml` in help
-- `/gcs:sync` - Shows as `[gcp] Custom command from sync.toml` in help
-
-### Conflict resolution
-
-Extension commands have the lowest precedence. When a conflict occurs with user
-or project commands:
-
-1. **No conflict**: Extension command uses its natural name (e.g., `/deploy`)
-2. **With conflict**: Extension command is renamed with the extension prefix
-   (e.g., `/gcp.deploy`)
-
-For example, if both a user and the `gcp` extension define a `deploy` command:
-
-- `/deploy` - Executes the user's deploy command
-- `/gcp.deploy` - Executes the extension's deploy command (marked with `[gcp]`
-  tag)
-
-## Variables
-
-Gemini CLI extensions allow variable substitution in `gemini-extension.json`.
-This can be useful if e.g., you need the current directory to run an MCP server
-using `"cwd": "${extensionPath}${/}run.ts"`.
-
-**Supported variables:**
-
-| variable                   | description                                                                                                                                                     |
-| -------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| `${extensionPath}`         | The fully-qualified path of the extension in the user's filesystem e.g., '/Users/username/.gemini/extensions/example-extension'. This will not unwrap symlinks. |
-| `${workspacePath}`         | The fully-qualified path of the current workspace.                                                                                                              |
-| `${/} or ${pathSeparator}` | The path separator (differs per OS).                                                                                                                            |

+# Extensions reference
+
+This guide covers the `gemini extensions` commands and the structure of the
+`gemini-extension.json` configuration file.
+
+## Extension management
+
+We offer a suite of extension management tools using `gemini extensions`
+commands.
+
+Note that these commands (e.g. `gemini extensions install`) are not supported
+from within the CLI's **interactive mode**, although you can list installed
+extensions using the `/extensions list` slash command.
+
+Note that all of these management operations (including updates to slash
+commands) will only be reflected in active CLI sessions on **restart**.
+
+### Installing an extension
+
+You can install an extension using `gemini extensions install` with either a
+GitHub URL or a local path.
+
+Note that we create a copy of the installed extension, so you will need to run
+`gemini extensions update` to pull in changes from both locally-defined
+extensions and those on GitHub.
+
+NOTE: If you are installing an extension from GitHub, you'll need to have `git`
+installed on your machine. See
+[git installation instructions](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
+for help.
+
+```
+gemini extensions install <source> [--ref <ref>] [--auto-update] [--pre-release] [--consent]
+```
+
+- `<source>`: The github URL or local path of the extension to install.
+- `--ref`: The git ref to install from.
+- `--auto-update`: Enable auto-update for this extension.
+- `--pre-release`: Enable pre-release versions for this extension.
+- `--consent`: Acknowledge the security risks of installing an extension and
+  skip the confirmation prompt.
+
+### Uninstalling an extension
+
+To uninstall one or more extensions, run
+`gemini extensions uninstall <name...>`:
+
+```
+gemini extensions uninstall gemini-cli-security gemini-cli-another-extension
+```
+
+### Disabling an extension
+
+Extensions are, by default, enabled across all workspaces. You can disable an
+extension entirely or for specific workspace.
+
+```
+gemini extensions disable <name> [--scope <scope>]
+```
+
+- `<name>`: The name of the extension to disable.
+- `--scope`: The scope to disable the extension in (`user` or `workspace`).
+
+### Enabling an extension
+
+You can enable extensions using `gemini extensions enable <name>`. You can also
+enable an extension for a specific workspace using
+`gemini extensions enable <name> --scope=workspace` from within that workspace.
+
+```
+gemini extensions enable <name> [--scope <scope>]
+```
+
+- `<name>`: The name of the extension to enable.
+- `--scope`: The scope to enable the extension in (`user` or `workspace`).
+
+### Updating an extension
+
+For extensions installed from a local path or a git repository, you can
+explicitly update to the latest version (as reflected in the
+`gemini-extension.json` `version` field) with `gemini extensions update <name>`.
+
+You can update all extensions with:
+
+```
+gemini extensions update --all
+```
+
+### Create a boilerplate extension
+
+We offer several example extensions `context`, `custom-commands`,
+`exclude-tools` and `mcp-server`. You can view these examples
+[here](https://github.com/google-gemini/gemini-cli/tree/main/packages/cli/src/commands/extensions/examples).
+
+To copy one of these examples into a development directory using the type of
+your choosing, run:
+
+```
+gemini extensions new <path> [template]
+```
+
+- `<path>`: The path to create the extension in.
+- `[template]`: The boilerplate template to use.
+
+### Link a local extension
+
+The `gemini extensions link` command will create a symbolic link from the
+extension installation directory to the development path.
+
+This is useful so you don't have to run `gemini extensions update` every time
+you make changes you'd like to test.
+
+```
+gemini extensions link <path>
+```
+
+- `<path>`: The path of the extension to link.
+
+## Extension format
+
+On startup, Gemini CLI looks for extensions in `<home>/.gemini/extensions`
+
+Extensions exist as a directory that contains a `gemini-extension.json` file.
+For example:
+
+`<home>/.gemini/extensions/my-extension/gemini-extension.json`
+
+### `gemini-extension.json`
+
+The `gemini-extension.json` file contains the configuration for the extension.
+The file has the following structure:
+
+```json
+{
+  "name": "my-extension",
+  "version": "1.0.0",
+  "description": "My awesome extension",
+  "mcpServers": {
+    "my-server": {
+      "command": "node my-server.js"
+    }
+  },
+  "contextFileName": "GEMINI.md",
+  "excludeTools": ["run_shell_command"]
+}
+```
+
+- `name`: The name of the extension. This is used to uniquely identify the
+  extension and for conflict resolution when extension commands have the same
+  name as user or project commands. The name should be lowercase or numbers and
+  use dashes instead of underscores or spaces. This is how users will refer to
+  your extension in the CLI. Note that we expect this name to match the
+  extension directory name.
+- `version`: The version of the extension.
+- `description`: A short description of the extension. This will be displayed on
+  [geminicli.com/extensions](https://geminicli.com/extensions).
+- `mcpServers`: A map of MCP servers to settings. The key is the name of the
+  server, and the value is the server configuration. These servers will be
+  loaded on startup just like MCP servers settingsd in a
+  [`settings.json` file](../get-started/configuration.md). If both an extension
+  and a `settings.json` file settings an MCP server with the same name, the
+  server defined in the `settings.json` file takes precedence.
+  - Note that all MCP server configuration options are supported except for
+    `trust`.
+- `contextFileName`: The name of the file that contains the context for the
+  extension. This will be used to load the context from the extension directory.
+  If this property is not used but a `GEMINI.md` file is present in your
+  extension directory, then that file will be loaded.
+- `excludeTools`: An array of tool names to exclude from the model. You can also
+  specify command-specific restrictions for tools that support it, like the
+  `run_shell_command` tool. For example,
+  `"excludeTools": ["run_shell_command(rm -rf)"]` will block the `rm -rf`
+  command. Note that this differs from the MCP server `excludeTools`
+  functionality, which can be listed in the MCP server config.
+
+When Gemini CLI starts, it loads all the extensions and merges their
+configurations. If there are any conflicts, the workspace configuration takes
+precedence.
+
+### Settings
+
+_Note: This is an experimental feature. We do not yet recommend extension
+authors introduce settings as part of their core flows._
+
+Extensions can define settings that the user will be prompted to provide upon
+installation. This is useful for things like API keys, URLs, or other
+configuration that the extension needs to function.
+
+To define settings, add a `settings` array to your `gemini-extension.json` file.
+Each object in the array should have the following properties:
+
+- `name`: A user-friendly name for the setting.
+- `description`: A description of the setting and what it's used for.
+- `envVar`: The name of the environment variable that the setting will be stored
+  as.
+- `sensitive`: Optional boolean. If true, obfuscates the input the user provides
+  and stores the secret in keychain storage. **Example**
+
+```json
+{
+  "name": "my-api-extension",
+  "version": "1.0.0",
+  "settings": [
+    {
+      "name": "API Key",
+      "description": "Your API key for the service.",
+      "envVar": "MY_API_KEY"
+    }
+  ]
+}
+```
+
+When a user installs this extension, they will be prompted to enter their API
+key. The value will be saved to a `.env` file in the extension's directory
+(e.g., `<home>/.gemini/extensions/my-api-extension/.env`).
+
+You can view a list of an extension's settings by running:
+
+```
+gemini extensions list
+```
+
+and you can update a given setting using:
+
+```
+gemini extensions config <extension name> [setting name] [--scope <scope>]
+```
+
+- `--scope`: The scope to set the setting in (`user` or `workspace`). This is
+  optional and will default to `user`.
+
+### Custom commands
+
+Extensions can provide [custom commands](../cli/custom-commands.md) by placing
+TOML files in a `commands/` subdirectory within the extension directory. These
+commands follow the same format as user and project custom commands and use
+standard naming conventions.
+
+**Example**
+
+An extension named `gcp` with the following structure:
+
+```
+.gemini/extensions/gcp/
+├── gemini-extension.json
+└── commands/
+    ├── deploy.toml
+    └── gcs/
+        └── sync.toml
+```
+
+Would provide these commands:
+
+- `/deploy` - Shows as `[gcp] Custom command from deploy.toml` in help
+- `/gcs:sync` - Shows as `[gcp] Custom command from sync.toml` in help
+
+### Hooks
+
+Extensions can provide [hooks](../hooks/index.md) to intercept and customize
+Gemini CLI behavior at specific lifecycle events. Hooks provided by an extension
+must be defined in a `hooks/hooks.json` file within the extension directory.
+
+> [!IMPORTANT] Hooks are not defined directly in `gemini-extension.json`. The
+> CLI specifically looks for the `hooks/hooks.json` file.
+
+### Agent Skills
+
+Extensions can bundle [Agent Skills](../cli/skills.md) to provide specialized
+workflows. Skills must be placed in a `skills/` directory within the extension.
+
+**Example**
+
+An extension with the following structure:
+
+```
+.gemini/extensions/my-extension/
+├── gemini-extension.json
+└── skills/
+    └── security-audit/
+        └── SKILL.md
+```
+
+Will expose a `security-audit` skill that the model can activate.
+
+### Sub-agents
+
+> **Note: Sub-agents are currently an experimental feature.**
+
+Extensions can provide [sub-agents](../core/subagents.md) that users can
+delegate tasks to.
+
+To bundle sub-agents with your extension, create an `agents/` directory in your
+extension's root folder and add your agent definition files (`.md`) there.
+
+**Example**
+
+```
+.gemini/extensions/my-extension/
+├── gemini-extension.json
+└── agents/
+    ├── security-auditor.md
+    └── database-expert.md
+```
+
+Gemini CLI will automatically discover and load these agents when the extension
+is installed and enabled.
+
+### Conflict resolution
+
+Extension commands have the lowest precedence. When a conflict occurs with user
+or project commands:
+
+1. **No conflict**: Extension command uses its natural name (e.g., `/deploy`)
+2. **With conflict**: Extension command is renamed with the extension prefix
+   (e.g., `/gcp.deploy`)
+
+For example, if both a user and the `gcp` extension define a `deploy` command:
+
+- `/deploy` - Executes the user's deploy command
+- `/gcp.deploy` - Executes the extension's deploy command (marked with `[gcp]`
+  tag)
+
+## Variables
+
+Gemini CLI extensions allow variable substitution in both
+`gemini-extension.json` and `hooks/hooks.json`. This can be useful if e.g., you
+need the current directory to run an MCP server using an argument like
+`"args": ["${extensionPath}${/}dist${/}server.js"]`.
+
+**Supported variables:**
+
