+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, system prompt (snippets.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.

+prompt = """
+You are an expert Reviewer and Pickle Rick Worker.
+
+Target: {{args}}
+
+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.
+        *   Use `git status` to see the state of the repository.
+    *   Otherwise:
+        *   Use `gh pr view {{args}}` to pull the information of the PR.
+        *   Use `gh pr diff {{args}}` to view the diff of the PR.
+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.

+description: Provides a step-by-step procedure for generating Gemini CLI changelog files based on github release information.
+---
+
+# Procedure: Updating Changelog for New Releases
+
+The following instructions are run by Gemini CLI when processing new releases.
+
+## Objective
+
+To standardize the process of updating the Gemini CLI changelog files for a new
+release, ensuring accuracy, consistency, and adherence to project style
+guidelines.
+
+## Release Types
+
+This skill covers two types of releases:
+
+*   **Standard Releases:** Regular, versioned releases that are announced to all
+    users. These updates modify `docs/changelogs/latest.md` and
+    `docs/changelogs/index.md`.
+*   **Preview Releases:** Pre-release versions for testing and feedback. These
+    updates only modify `docs/changelogs/preview.md`.
+
+Ignore all other releases, such as nightly releases.
+
+### Expected Inputs
+
+Regardless of the type of release, the following information is expected:
+
+*   **New version number:** The version number for the new release
+    (e.g., `v0.27.0`).
+*   **Release date:** The date of the new release (e.g., `2026-02-03`).
+*   **Raw changelog data:** A list of all pull requests and changes
+    included in the release, in the format `description by @author in
+    #pr_number`.
+*   **Previous version number:** The version number of the last release can be
+    calculated by decreasing the minor version number by one and setting the
+    patch or bug fix version number.
+
+## Procedure
+
+### Initial Setup
+
+1.  Identify the files to be modified: 
+
+    For standard releases, update `docs/changelogs/latest.md` and
+    `docs/changelogs/index.md`. For preview releases, update
+    `docs/changelogs/preview.md`.
+
+2.  Activate the `docs-writer` skill.
+
+### Analyze Raw Changelog Data
+
+1.  Review the complete list of changes. If it is a patch or a bug fix with few
+    changes, skip to the "Update `docs/changelogs/latest.md` or
+    `docs/changelogs/preview.md`" section.
+
+2.  Group related changes into high-level categories such as
+    important features, "UI/UX Improvements", and "Bug Fixes". Use the existing
+    announcements in `docs/changelogs/index.md` as an example.
+
+### Create Highlight Summaries
+
+Create two distinct versions of the release highlights.
+
+**Important:** Carefully inspect highlights for "experimental" or
+"preview" features before public announcement, and do not include them.
+
+#### Version 1: Comprehensive Highlights (for `latest.md` or `preview.md`)
+
+Write a detailed summary for each category focusing on user-facing
+impact.
+
+#### Version 2: Concise Highlights (for `index.md`)
+
+Skip this step for preview releases.
+
+Write concise summaries including the primary PR and author
+(e.g., `([#12345](link) by @author)`).
+
+### Update `docs/changelogs/latest.md` or `docs/changelogs/preview.md`
+
+1. Read current content and use `write_file` to replace it with the new
+  version number, and date.
+  
+  If it is a patch or bug fix with few changes, simply add these
+  changes to the "What's Changed" list. Otherwise, replace comprehensive
+  highlights, and the full "What's Changed" list. 
+
+2. For each item in the "What's Changed" list, keep usernames in plaintext, and
+  add github links for each issue number. Example:
+
+  "- feat: implement /rewind command by @username in
+  [#12345](https://github.com/google-gemini/gemini-cli/pull/12345)"
+
+3. Skip entries by @gemini-cli-robot.
+
+4. Do not add the "New Contributors" section.
+
+5. Update the "Full changelog:" link by doing one of following:
+
+   If it is a patch or bug fix with few changes, retain the original link
+   but replace the latter version with the new version. For example, if the
+   patch is version is "v0.28.1", replace the latter version:
+   "https://github.com/google-gemini/gemini-cli/compare/v0.27.0...v0.28.0" with
+   "https://github.com/google-gemini/gemini-cli/compare/v0.27.0...v0.28.1".
+   
+   Otherwise, for minor and major version changes, replace the link with the
+   one included at the end of the changelog data.
+
+6. Ensure lines are wrapped to 80 characters.
+
+### Update `docs/changelogs/index.md`
+
+Skip this step for patches, bug fixes, or preview releases.
+
+Insert a new "Announcements" section for the new version directly
+above the previous version's section. Ensure lines are wrapped to
+80 characters.
+
+### Finalize
+
+Run `npm run format` to ensure consistency.

+# `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.

 ## Development Conventions
 
+- **Legacy Snippets:** `packages/core/src/prompts/snippets.legacy.ts` is a
+  snapshot of an older system prompt. Avoid changing the prompting verbiage to
+  preserve its historical behavior; however, structural changes to ensure
+  compilation or simplify the code are permitted.
 - **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.
+  Always activate the `pr-creator` skill for PR generation, even when using the
+  `gh` CLI.
 - **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).
+- **License Headers:** For all new source code files (`.ts`, `.tsx`, `.js`),
+  include the Apache-2.0 license header with the current year. (e.g.,
+  `Copyright 2026 Google LLC`). This is 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', '')`.

-- Architecture overview: `docs/architecture.md`.
-- Contribution guide: `CONTRIBUTING.md`.
-- Documentation is organized via `docs/sidebar.json`.

+- 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.

 ## Highlights
 
-- **Skills and Agents Improvements:** Enhanced `activate_skill` tool, new
-  `pr-creator` skill, default enablement of skills, improved `cli_help` agent,
-  and a new `/agents refresh` command.
-- **UI/UX Refinements:** Transparent feedback for skills, ability to switch
-  focus between shell and input with Tab, and dynamic terminal tab titles.
-- **Core Functionality & Performance:** Support for built-in agent skills,
-  refined Gemini 3 system instructions, caching ignore instances for
-  performance, and improved retry mechanisms.
-- **Bug Fixes and Stability:** Numerous bug fixes across the CLI, core, and
-  workflows, including issues with subagent delegation, unicode character
-  crashes, and sticky header regressions.
+- **Event-Driven Architecture:** The CLI now uses an event-driven scheduler for
+  tool execution, improving performance and responsiveness. This includes
+  migrating non-interactive flows and sub-agents to the new scheduler.
+- **Enhanced User Experience:** This release introduces several UI/UX
+  improvements, including queued tool confirmations and the ability to expand
+  and collapse large pasted text blocks. The `Settings` dialog has been improved
+  to reduce jitter and preserve focus.
+- **Agent and Skill Improvements:** Agent Skills have been promoted to a stable
+  feature. Sub-agents now use a JSON schema for input and are tracked by an
+  `AgentRegistry`.
+- **New `/rewind` Command:** A new `/rewind` command has been implemented to
+  allow users to go back in their session history.
+- **Improved Shell and File Handling:** The shell tool's output format has been
+  optimized, and the CLI now gracefully handles disk-full errors during chat
+  recording. A bug in detecting already added paths has been fixed.
+- **Linux Clipboard Support:** Image pasting capabilities for Wayland and X11 on
+  Linux have been added.

+# 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.

+## 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

+# Plan Mode (experimental)
+
+Plan Mode is a safe, read-only mode for researching and designing complex
+changes. It prevents modifications while you research, design and plan an
+implementation strategy.
+
+> **Note: Plan Mode is currently an experimental feature.**
+>
+> Experimental features are subject to change. To use Plan Mode, enable it via
+> `/settings` (search for `Plan`) or add the following to your `settings.json`:
+>
+> ```json
+> {
+>   "experimental": {
+>     "plan": true
+>   }
+> }
+> ```
+>
+> Your feedback is invaluable as we refine this feature. If you have ideas,
+> suggestions, or encounter issues:
+>
+> - Use the `/bug` command within the CLI to file an issue.
+> - [Open an issue](https://github.com/google-gemini/gemini-cli/issues) on
+>   GitHub.

+
+## Starting in Plan Mode
+
+You can configure Gemini CLI to start directly in Plan Mode by default:
+
+1.  Type `/settings` in the CLI.
+2.  Search for `Default Approval Mode`.
+3.  Set the value to `Plan`.
+
+Other ways to start in Plan Mode:
+
+- **CLI Flag:** `gemini --approval-mode=plan`
+- **Manual Settings:** Manually update your `settings.json`:
+
+  ```json
+  {
+    "general": {
+      "defaultApprovalMode": "plan"
+    }
+  }
+  ```
+
+## How to use Plan Mode
+
+### Entering Plan Mode
+
+You can enter Plan Mode in three ways:
+
+1.  **Keyboard Shortcut:** Press `Shift+Tab` to cycle through approval modes
+    (`Default` -> `Plan` -> `Auto-Edit`).
+2.  **Command:** Type `/plan` in the input box.
+3.  **Natural Language:** Ask the agent to "start a plan for...".
+
+### The Planning Workflow
+
+1.  **Requirements:** The agent clarifies goals using `ask_user`.
+2.  **Exploration:** The agent uses read-only tools (like [`read_file`]) to map
+    the codebase and validate assumptions.
+3.  **Planning:** A detailed plan is written to a temporary Markdown file.
+4.  **Review:** You review the plan.
+    - **Approve:** Exit Plan Mode and start implementation (switching to
+      Auto-Edit or Default approval mode).
+    - **Iterate:** Provide feedback to refine the plan.
+
+### Exiting Plan Mode
+
+To exit Plan Mode:
+
+1. **Keyboard Shortcut:** Press `Shift+Tab` to cycle to the desired mode.
+1. **Tool:** The agent calls the `exit_plan_mode` tool to present the finalized
+   plan for your approval.
+
+## Tool Restrictions
+
+Plan Mode enforces strict safety policies to prevent accidental changes.
+
+These are the only allowed tools:
+
+- **FileSystem (Read):** [`read_file`], [`list_directory`], [`glob`]
+- **Search:** [`grep_search`], [`google_web_search`]
+- **Interaction:** `ask_user`
+- **MCP Tools (Read):** Read-only [MCP tools] (e.g., `github_read_issue`,
+  `postgres_read_schema`) are allowed.
+- **Planning (Write):** [`write_file`] and [`replace`] ONLY allowed for `.md`
+  files in the `~/.gemini/tmp/<project>/plans/` directory.

+# 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.

-## Creating a Skill
-
-A skill is a directory containing a `SKILL.md` file at its root. This file uses
-YAML frontmatter for metadata and Markdown for instructions.
-
-### Folder Structure
-
-Skills are self-contained directories. At a minimum, a skill requires a
-`SKILL.md` file, but can include other resources:
-
-```text
-my-skill/
-├── SKILL.md       (Required) Instructions and metadata
-├── scripts/       (Optional) Executable scripts/tools
-├── references/    (Optional) Static documentation and examples
-└── assets/        (Optional) Templates and binary resources
-```
-
-### Basic Structure (SKILL.md)
-
-```markdown
----
-name: <unique-name>
-description: <what the skill does and when Gemini should use it>
----
-
-<your instructions for how the agent should behave / use the skill>
-```
-
-- **`name`**: A unique identifier (lowercase, alphanumeric, and dashes).
-- **`description`**: The most critical field. Gemini uses this to decide when
-  the skill is relevant. Be specific about the expertise provided.
-- **Body**: Everything below the second `---` is injected as expert procedural
-  guidance for the model.
-
-### Example: Team Code Reviewer
-
-Create `~/.gemini/skills/code-reviewer/SKILL.md`:
-
-```markdown
----
-name: code-reviewer
-description:
-  Expertise in reviewing code for style, security, and performance. Use when the
-  user asks for "feedback," a "review," or to "check" their changes.
----
-
-# Code Reviewer
-
-You are an expert code reviewer. When reviewing code, follow this workflow:
-
-1.  **Analyze**: Review the staged changes or specific files provided. Ensure
-    that the changes are scoped properly and represent minimal changes required
-    to address the issue.
-2.  **Style**: Ensure code follows the workspace's conventions and idiomatic
-    patterns as described in the `GEMINI.md` file.
-3.  **Security**: Flag any potential security vulnerabilities.
-4.  **Tests**: Verify that new logic has corresponding test coverage and that
-    the test coverage adequately validates the changes.
-
-Provide your feedback as a concise bulleted list of "Strengths" and
-"Opportunities."
-```
-
-### Resource Conventions
-
-While you can structure your skill directory however you like, the Agent Skills
-standard encourages these conventions:
-
-- **`scripts/`**: Executable scripts (bash, python, node) the agent can run.
-- **`references/`**: Static documentation, schemas, or example data for the
-  agent to consult.
-- **`assets/`**: Code templates, boilerplate, or binary resources.
-
-When a skill is activated, Gemini CLI provides the model with a tree view of the
-entire skill directory, allowing it to discover and utilize these assets.

       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.

+# 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:

+
+## Configuration
+
+To use remote subagents, you must explicitly enable them in your

+
+```json
+{
+  "experimental": {
+    "enableAgents": true
+  }
+}

+# 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.
+```
+
+### Configuration schema

+| Field          | Type   | Required | Description                                                                                                                |
+| :------------- | :----- | :------- | :------------------------------------------------------------------------------------------------------------------------- |
+| `name`         | string | Yes      | Unique identifier (slug) used as the tool name for the agent. Only lowercase letters, numbers, hyphens, and underscores.   |
+| `description`  | string | Yes      | Short description of what the agent does. This is visible to the main agent to help it decide when to call this sub-agent. |
+| `kind`         | string | No       | `local` (default) or `remote`.                                                                                             |
+| `tools`        | array  | No       | List of tool names this agent can use. If omitted, it may have access to a default set.                                    |
+| `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

+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.

-
-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 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.
-
-## 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 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 settings 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:
-
-```
+```bash
 gemini extensions list
 ```
 
-and you can update a given setting using:
+## Installation
 
-```
-gemini extensions config <extension name> [setting name] [--scope <scope>]
+To install a real extension, you can use the `extensions install` command with a
+GitHub repository URL in noninteractive mode. For example:
+
+```bash
+gemini extensions install https://github.com/gemini-cli-extensions/workspace
 ```
 
-- `--scope`: The scope to set the setting in (`user` or `workspace`). This is
-  optional and will default to `user`.
+## Next steps
 
-### 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
-
-### Agent Skills
-
-_Note: This is an experimental feature enabled via `experimental.skills`._
-
-Extensions can bundle [Agent Skills](../cli/skills.md) to provide on-demand
-expertise and specialized workflows. To include skills in your extension, place
-them in a `skills/` subdirectory within the extension directory. Each skill must
-follow the [Agent Skills structure](../cli/skills.md#folder-structure),
-including a `SKILL.md` file.
-
-**Example**
-
-An extension named `security-toolkit` with the following structure:
-
-```
-.gemini/extensions/security-toolkit/
-├── gemini-extension.json
-└── skills/
-    ├── audit/
-    │   ├── SKILL.md
-    │   └── scripts/
-    │       └── scan.py
-    └── hardening/
-        └── SKILL.md
-```
-
-Upon installation, these skills will be discovered by Gemini CLI and can be
-activated during a session when the model identifies a task matching their
-descriptions.
-
-Extension skills have the lowest precedence and will be overridden by user or
-workspace skills of the same name. They can be viewed and managed (enabled or
-disabled) using the [`/skills` command](../cli/skills.md#managing-skills).
-
-### 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.
-
-#### Directory structure
-
-```
-.gemini/extensions/my-extension/
-├── gemini-extension.json
-└── hooks/
-    └── hooks.json
-```
-
-#### `hooks/hooks.json` format
-
-The `hooks.json` file contains a `hooks` object where keys are
-[event names](../hooks/reference.md#supported-events) and values are arrays of
-[hook definitions](../hooks/reference.md#hook-definition).
-
-```json
-{
-  "hooks": {
-    "before_agent": [
-      {
-        "hooks": [
-          {
-            "type": "command",
-            "command": "node ${extensionPath}/scripts/setup.js",
-            "name": "Extension Setup"
-          }
-        ]
-      }
-    ]
-  }
-}
-```
-
-#### Supported variables
-
-Just like `gemini-extension.json`, the `hooks/hooks.json` file supports
-[variable substitution](#variables). This is particularly useful for referencing
-scripts within the extension directory using `${extensionPath}`.
-
-### 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 or hook script 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 ${pathSeparator}` | The path separator (differs per OS).                                                                                                                            |
-| `${process.execPath}`      | The path to the Node.js binary executing the CLI.                                                                                                               |

+# 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:**
+
+| variable                   | description                                                                                                                                                     |

We also support MCP resources (which can replace custom commands) and system instructions (which can replace custom context) | Model                 |
+| **[Custom commands](../cli/custom-commands.md)**               | A shortcut (like `/my-cmd`) that executes a pre-defined prompt or shell command.                                   | Use this for repetitive tasks or to save long, complex prompts that you use frequently.

-For large inputs, use streaming JSON parsers to avoid loading everything into

-// Standard approach: parse entire input
-const input = JSON.parse(await readStdin());
-const content = input.tool_input.content;

-## Troubleshooting
-
-### Hook not executing
-
-**Check hook name in `/hooks panel`:**
-
-```bash
-/hooks panel
-```
-
-Verify the hook appears in the list and is enabled.
-
-**Verify matcher pattern:**
-
-```bash
-# Test regex pattern
-echo "write_file|replace" | grep -E "write_.*|replace"
-```
-
-**Check disabled list:**
-
-```json
-{
-  "hooks": {
-    "disabled": ["my-hook-name"]
-  }
-}
-```
-
-**Ensure script is executable:**
-
-```bash
-ls -la .gemini/hooks/my-hook.sh
-chmod +x .gemini/hooks/my-hook.sh
-```
-
-**Verify script path:**
-
-```bash
-# Check path expansion
-echo "$GEMINI_PROJECT_DIR/.gemini/hooks/my-hook.sh"
-
-# Verify file exists
-test -f "$GEMINI_PROJECT_DIR/.gemini/hooks/my-hook.sh" && echo "File exists"
-```
-
-### Hook timing out
-
-**Check configured timeout:**
-
-```json
-{
-  "name": "slow-hook",
-  "timeout": 60000
-}
-```
-
-**Optimize slow operations:**
-
-```javascript
-// Before: Sequential operations (slow)
-for (const item of items) {
-  await processItem(item);
-}
-
-// After: Parallel operations (fast)
-await Promise.all(items.map((item) => processItem(item)));
-```
-
-**Use caching:**
-
-```javascript
-const cache = new Map();
-
-async function getCachedData(key) {
-  if (cache.has(key)) {
-    return cache.get(key);
-  }
-  const data = await fetchData(key);
-  cache.set(key, data);
-  return data;
-}
-```
-
-**Consider splitting into multiple faster hooks:**
-
-```json
-{
-  "hooks": {
-    "BeforeTool": [
-      {
-        "matcher": "write_file",
-        "hooks": [

-          }
-        ]
-      }
-    ]
-  }
-}
-```
-
-### Invalid JSON output
-
-**Validate JSON before outputting:**
-
-```bash
-#!/usr/bin/env bash
-output='{"decision": "allow"}'
-
-# Validate JSON
-if echo "$output" | jq empty 2>/dev/null; then
-  echo "$output"
-else
-  echo "Invalid JSON generated" >&2
-  exit 1
-fi
-```
-
-**Ensure proper quoting and escaping:**
-
-```javascript
-// Bad: Unescaped string interpolation
-const message = `User said: ${userInput}`;
-console.log(JSON.stringify({ message }));
-
-// Good: Automatic escaping
-console.log(JSON.stringify({ message: `User said: ${userInput}` }));
-```
-
-**Check for binary data or control characters:**
-
-```javascript
-function sanitizeForJSON(str) {
-  return str.replace(/[\x00-\x1F\x7F-\x9F]/g, ''); // Remove control chars
-}
-
-const cleanContent = sanitizeForJSON(content);
-console.log(JSON.stringify({ content: cleanContent }));
-```
-
-### Exit code issues
-
-**Verify script returns correct codes:**
-
-```bash
-#!/usr/bin/env bash
-set -e  # Exit on error
-
-# Processing logic
-if validate_input; then
-  echo "Success"
-  exit 0
-else
-  echo "Validation failed" >&2
-  exit 2
-fi
-```
-
-**Check for unintended errors:**
-
-```bash
-#!/usr/bin/env bash
-# Don't use 'set -e' if you want to handle errors explicitly
-# set -e
-
-if ! command_that_might_fail; then
-  # Handle error
-  echo "Command failed but continuing" >&2
-fi
-
-# Always exit explicitly
-exit 0

 Hooks are scripts or programs that Gemini CLI executes at specific points in the

 ## What are hooks?
 
-With hooks, you can:
-
-- **Add context:** Inject relevant information before the model processes a
-  request
-- **Validate actions:** Review and block potentially dangerous operations
-- **Enforce policies:** Implement security and compliance requirements
-- **Log interactions:** Track tool usage and model responses
-- **Optimize behavior:** Dynamically adjust tool selection or model parameters
-
 Hooks run synchronously as part of the agent loop—when a hook event fires,
 Gemini CLI waits for all matching hooks to complete before continuing.
 
-## Security and Risks
+With hooks, you can:
 
-> **Warning: Hooks execute arbitrary code with your user privileges.**
->
-> By configuring hooks, you are explicitly allowing Gemini CLI to run shell
-> commands on your machine. Malicious or poorly configured hooks can:
+- **Add context:** Inject relevant information (like git history) before the
+  model processes a request.
+- **Validate actions:** Review tool arguments and block potentially dangerous
+  operations.
+- **Enforce policies:** Implement security scanners and compliance checks.
+- **Log interactions:** Track tool usage and model responses for auditing.
+- **Optimize behavior:** Dynamically filter available tools or adjust model
+  parameters.
 
-- **Exfiltrate data**: Read sensitive files (`.env`, ssh keys) and send them to
-  remote servers.
-- **Modify system**: Delete files, install malware, or change system settings.
-- **Consume resources**: Run infinite loops or crash your system.
+### Getting started
 
-**Project-level hooks** (in `.gemini/settings.json`) and **Extension hooks** are
-particularly risky when opening third-party projects or extensions from
-untrusted authors. Gemini CLI will **warn you** the first time it detects a new
-project hook (identified by its name and command), but it is **your
-responsibility** to review these hooks (and any installed extensions) before
-trusting them.
-
-> **Note:** Extension hooks are subject to a mandatory security warning and
-> consent flow during extension installation or update if hooks are detected.
-> You must explicitly approve the installation or update of any extension that
-> contains hooks.

 ### Hook events
 
-Hooks are triggered by specific events in Gemini CLI's lifecycle. The following
-table lists all available hook events:

-### Hook types
+### Global mechanics
 
-Gemini CLI currently supports **command hooks** that run shell commands or
-scripts:
+Understanding these core principles is essential for building robust hooks.
 
-```json
-{
-  "type": "command",
-  "command": "$GEMINI_PROJECT_DIR/.gemini/hooks/my-hook.sh",
-  "timeout": 30000
-}
-```
+#### Strict JSON requirements (The "Golden Rule")
 
-**Note:** Plugin hooks (npm packages) are planned for a future release.
+Hooks communicate via `stdin` (Input) and `stdout` (Output).
 
-### Matchers
+1. **Silence is Mandatory**: Your script **must not** print any plain text to
+   `stdout` other than the final JSON object. **Even a single `echo` or `print`
+   call before the JSON will break parsing.**
+2. **Pollution = Failure**: If `stdout` contains non-JSON text, parsing will
+   fail. The CLI will default to "Allow" and treat the entire output as a
+   `systemMessage`.
+3. **Debug via Stderr**: Use `stderr` for **all** logging and debugging (e.g.,
+   `echo "debug" >&2`). Gemini CLI captures `stderr` but never attempts to parse
+   it as JSON.
 
-For tool-related events (`BeforeTool`, `AfterTool`), you can filter which tools
-trigger the hook:
+#### Exit codes
+
+Gemini CLI uses exit codes to determine the high-level outcome of a hook
+execution:
+
+| Exit Code | Label            | Behavioral Impact                                                                                                                                                            |
+| --------- | ---------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **0**     | **Success**      | The `stdout` is parsed as JSON. **Preferred code** for all logic, including intentional blocks (e.g., `{"decision": "deny"}`).                                               |
+| **2**     | **System Block** | **Critical Block**. The target action (tool, turn, or stop) is aborted. `stderr` is used as the rejection reason. High severity; used for security stops or script failures. |
+| **Other** | **Warning**      | Non-fatal failure. A warning is shown, but the interaction proceeds using original parameters.                                                                               |
+
+#### Matchers
+
+You can filter which specific tools or triggers fire your hook using the
+`matcher` field.
+
+- **Tool events** (`BeforeTool`, `AfterTool`): Matchers are **Regular
+  Expressions**. (e.g., `"write_.*"`).
+- **Lifecycle events**: Matchers are **Exact Strings**. (e.g., `"startup"`).
+- **Wildcards**: `"*"` or `""` (empty string) matches all occurrences.
+
+## Configuration
+
+Hooks are configured in `settings.json`. Gemini CLI merges configurations from
+multiple layers in the following order of precedence (highest to lowest):
+
+1.  **Project settings**: `.gemini/settings.json` in the current directory.
+2.  **User settings**: `~/.gemini/settings.json`.
+3.  **System settings**: `/etc/gemini-cli/settings.json`.
+4.  **Extensions**: Hooks defined by installed extensions.

-## Configuration
-
-Hook definitions are configured in `settings.json` files using the `hooks`
-object. Configuration can be specified at multiple levels with defined
-precedence rules.
-
-### Configuration layers
-
-Hook configurations are applied in the following order of execution (lower
-numbers run first):
-
-1.  **Project settings:** `.gemini/settings.json` in your project directory
-    (highest priority)
-2.  **User settings:** `~/.gemini/settings.json`
-3.  **System settings:** `/etc/gemini-cli/settings.json`
-4.  **Extensions:** Internal hooks defined by installed extensions (lowest
-    priority). See [Extensions documentation](../extensions/index.md#hooks) for
-    details on how extensions define and configure hooks.
-
-#### Deduplication and shadowing
-
-If multiple hooks with the identical **name** and **command** are discovered
-across different configuration layers, Gemini CLI deduplicates them. The hook
-from the higher-priority layer (e.g., Project) will be kept, and others will be
-ignored.
-
-Within each level, hooks run in the order they are declared in the
-configuration.

 ### Environment variables
 
-Hooks have access to:
+Hooks are executed with a sanitized environment.
 
-- `GEMINI_PROJECT_DIR`: Project root directory
-- `GEMINI_SESSION_ID`: Current session ID
-- `GEMINI_API_KEY`: Gemini API key (if configured)
-- All other environment variables from the parent process
+- `GEMINI_PROJECT_DIR`: The absolute path to the project root.
+- `GEMINI_SESSION_ID`: The unique ID for the current session.
+- `GEMINI_CWD`: The current working directory.
+- `CLAUDE_PROJECT_DIR`: (Alias) Provided for compatibility.
+
+## Security and risks
+
+> **Warning: Hooks execute arbitrary code with your user privileges.** By
+> configuring hooks, you are allowing scripts to run shell commands on your
+> machine.
+
+**Project-level hooks** are particularly risky when opening untrusted projects.
+Gemini CLI **fingerprints** project hooks. If a hook's name or command changes
+(e.g., via `git pull`), it is treated as a **new, untrusted hook** and you will
+be warned before it executes.
+
+See [Security Considerations](/docs/hooks/best-practices#using-hooks-securely)
+for a detailed threat model.
 
 ## Managing hooks
 
-### View registered hooks
+Use the CLI commands to manage hooks without editing JSON manually:
 
-Use the `/hooks panel` command to view all registered hooks:
-
-```bash
-/hooks panel
-```
-
-This command displays:
-
-- All configured hooks organized by event
-- Hook source (user, project, system)
-- Hook type (command or plugin)
-- Individual hook status (enabled/disabled)
-
-### Enable and disable all hooks at once
-
-You can enable or disable all hooks at once using commands:
-
-```bash
-/hooks enable-all
-/hooks disable-all
-```
-
-These commands provide a shortcut to enable or disable all configured hooks
-without managing them individually. The `enable-all` command removes all hooks
-from the `hooks.disabled` array, while `disable-all` adds all configured hooks
-to the disabled list. Changes take effect immediately without requiring a
-restart.
-
-### Enable and disable individual hooks
-
-You can enable or disable individual hooks using commands:
-
-```bash
-/hooks enable hook-name
-/hooks disable hook-name
-```
-
-These commands allow you to control hook execution without editing configuration
-files. The hook name should match the `name` field in your hook configuration.
-Changes made via these commands are persisted to your settings. The settings are
-saved to workspace scope if available, otherwise to your global user settings
-(`~/.gemini/settings.json`).
-
-### Disabled hooks configuration
-
-To permanently disable hooks, add them to the `hooks.disabled` array in your
-`settings.json`:
-
-```json
-{
-  "hooks": {
-    "disabled": ["secret-scanner", "auto-test"]
-  }
-}
-```
-
-**Note:** The `hooks.disabled` array uses a UNION merge strategy. Disabled hooks
-from all configuration levels (user, project, system) are combined and
-deduplicated, meaning a hook disabled at any level remains disabled.
-
-## Migration from Claude Code
-
-If you have hooks configured for Claude Code, you can migrate them:
-
-```bash
-gemini hooks migrate --from-claude
-```
-
-This command:
-
-- Reads `.claude/settings.json`
-- Converts event names (`PreToolUse` → `BeforeTool`, etc.)
-- Translates tool names (`Bash` → `run_shell_command`, `replace` → `replace`)
-- Updates matcher patterns
-- Writes to `.gemini/settings.json`

-# Hooks Reference
+# Hooks reference
 
 This document provides the technical specification for Gemini CLI hooks,
-including the JSON schemas for input and output, exit code behaviors, and the
-stable model API.
+including JSON schemas and API details.
 
-## Communication Protocol
+## Global hook mechanics
 
-Hooks communicate with Gemini CLI via standard streams and exit codes:
-
-- **Input**: Gemini CLI sends a JSON object to the hook's `stdin`.
-- **Output**: The hook sends a JSON object (or plain text) to `stdout`.
-- **Exit Codes**: Used to signal success or blocking errors.
-
-### Exit Code Behavior
-
-| Exit Code | Meaning            | Behavior                                                                                        |
-| :-------- | :----------------- | :---------------------------------------------------------------------------------------------- |
-| `0`       | **Success**        | `stdout` is parsed as JSON. If parsing fails, it's treated as a `systemMessage`.                |
-| `2`       | **Blocking Error** | Interrupts the current operation. `stderr` is shown to the agent (for tool events) or the user. |
-| Other     | **Warning**        | Execution continues. `stderr` is logged as a non-blocking warning.                              |
+- **Communication**: `stdin` for Input (JSON), `stdout` for Output (JSON), and
+  `stderr` for logs and feedback.
+- **Exit codes**:
+  - `0`: Success. `stdout` is parsed as JSON. **Preferred for all logic.**
+  - `2`: System Block. The action is blocked; `stderr` is used as the rejection
+    reason.
+  - `Other`: Warning. A non-fatal failure occurred; the CLI continues with a
+    warning.
+- **Silence is Mandatory**: Your script **must not** print any plain text to
+  `stdout` other than the final JSON.

-## Input Schema (`stdin`)
+## Configuration schema
 
-Every hook receives a base JSON object. Extra fields are added depending on the
-specific event.
+Hooks are defined in `settings.json` within the `hooks` object. Each event
+(e.g., `BeforeTool`) contains an array of **hook definitions**.
 
-### Base Fields (All Events)
+### Hook definition
 
-| Field             | Type     | Description                                           |
-| :---------------- | :------- | :---------------------------------------------------- |
-| `session_id`      | `string` | Unique identifier for the current CLI session.        |
-| `transcript_path` | `string` | Path to the session's JSON transcript (if available). |
-| `cwd`             | `string` | The current working directory.                        |

+| :----------- | :-------- | :------- | :-------------------------------------------------------------------------------------- |
+| `matcher`    | `string`  | No       | A regex (for tools) or exact string (for lifecycle) to filter when the hook runs.       |
+| `sequential` | `boolean` | No       | If `true`, hooks in this group run one after another. If `false`, they run in parallel. |
+| `hooks`      | `array`   | **Yes**  | An array of **hook configurations**.                                                    |

+
+## Tool hooks
+
+### Matchers and tool names
+
+For `BeforeTool` and `AfterTool` events, the `matcher` field in your settings is
+compared against the name of the tool being executed.
+
+- **Built-in Tools**: You can match any built-in tool (e.g., `read_file`,
+  `run_shell_command`). See the [Tools Reference](/docs/tools) for a full list
+  of available tool names.
+- **MCP Tools**: Tools from MCP servers follow the naming pattern
+  `mcp__<server_name>__<tool_name>`.
+- **Regex Support**: Matchers support regular expressions (e.g.,
+  `matcher: "read_.*"` matches all file reading tools).
+
+### `BeforeTool`
+
+Fires before a tool is invoked. Used for argument validation, security checks,
+and parameter rewriting.
+
+- **Input Fields**:
+  - `tool_name`: (`string`) The name of the tool being called.
+  - `tool_input`: (`object`) The raw arguments generated by the model.
+  - `mcp_context`: (`object`) Optional metadata for MCP-based tools.
+- **Relevant Output Fields**:
+  - `decision`: Set to `"deny"` (or `"block"`) to prevent the tool from
+    executing.
+  - `reason`: Required if denied. This text is sent **to the agent** as a tool
+    error, allowing it to respond or retry.
+  - `hookSpecificOutput.tool_input`: An object that **merges with and
+    overrides** the model's arguments before execution.
+  - `continue`: Set to `false` to **kill the entire agent loop** immediately.
+- **Exit Code 2 (Block Tool)**: Prevents execution. Uses `stderr` as the
+  `reason` sent to the agent. **The turn continues.**
+
+### `AfterTool`
+
+Fires after a tool executes. Used for result auditing, context injection, or
+hiding sensitive output from the agent.
+
+- **Input Fields**:
+  - `tool_name`: (`string`)
+  - `tool_input`: (`object`) The original arguments.
+  - `tool_response`: (`object`) The result containing `llmContent`,
+    `returnDisplay`, and optional `error`.
+  - `mcp_context`: (`object`)
+- **Relevant Output Fields**:
+  - `decision`: Set to `"deny"` to hide the real tool output from the agent.
+  - `reason`: Required if denied. This text **replaces** the tool result sent
+    back to the model.
+  - `hookSpecificOutput.additionalContext`: Text that is **appended** to the
+    tool result for the agent.
+  - `continue`: Set to `false` to **kill the entire agent loop** immediately.
+- **Exit Code 2 (Block Result)**: Hides the tool result. Uses `stderr` as the
+  replacement content sent to the agent. **The turn continues.**
+
+---
+
+## Agent hooks
+
+### `BeforeAgent`
+
+Fires after a user submits a prompt, but before the agent begins planning. Used
+for prompt validation or injecting dynamic context.
+
+- **Input Fields**:
+  - `prompt`: (`string`) The original text submitted by the user.
+- **Relevant Output Fields**:
+  - `hookSpecificOutput.additionalContext`: Text that is **appended** to the
+    prompt for this turn only.
+  - `decision`: Set to `"deny"` to block the turn and **discard the user's
+    message** (it will not appear in history).
+  - `continue`: Set to `false` to block the turn but **save the message to
+    history**.
+  - `reason`: Required if denied or stopped.
+- **Exit Code 2 (Block Turn)**: Aborts the turn and erases the prompt from
+  context. Same as `decision: "deny"`.
+
+### `AfterAgent`
+
+Fires once per turn after the model generates its final response. Primary use
+case is response validation and automatic retries.
+
+- **Input Fields**:
+  - `prompt`: (`string`) The user's original request.
+  - `prompt_response`: (`string`) The final text generated by the agent.
+  - `stop_hook_active`: (`boolean`) Indicates if this hook is already running as
+    part of a retry sequence.
+- **Relevant Output Fields**:
+  - `decision`: Set to `"deny"` to **reject the response** and force a retry.
+  - `reason`: Required if denied. This text is sent **to the agent as a new
+    prompt** to request a correction.
+  - `continue`: Set to `false` to **stop the session** without retrying.
+  - `hookSpecificOutput.clearContext`: If `true`, clears conversation history
+    (LLM memory) while preserving UI display.
+- **Exit Code 2 (Retry)**: Rejects the response and triggers an automatic retry
+  turn using `stderr` as the feedback prompt.
+
+---
+
+## Model hooks
+
+### `BeforeModel`
+
+Fires before sending a request to the LLM. Operates on a stable, SDK-agnostic
+request format.
+
+- **Input Fields**:
+  - `llm_request`: (`object`) Contains `model`, `messages`, and `config`
+    (generation params).
+- **Relevant Output Fields**:
+  - `hookSpecificOutput.llm_request`: An object that **overrides** parts of the
+    outgoing request (e.g., changing models or temperature).
+  - `hookSpecificOutput.llm_response`: A **Synthetic Response** object. If
+    provided, the CLI skips the LLM call entirely and uses this as the response.
+  - `decision`: Set to `"deny"` to block the request and abort the turn.
+- **Exit Code 2 (Block Turn)**: Aborts the turn and skips the LLM call. Uses
+  `stderr` as the error message.
+
+### `BeforeToolSelection`
+
+Fires before the LLM decides which tools to call. Used to filter the available
+toolset or force specific tool modes.
+
+- **Input Fields**:
+  - `llm_request`: (`object`) Same format as `BeforeModel`.
+- **Relevant Output Fields**:
+  - `hookSpecificOutput.toolConfig.mode`: (`"AUTO" | "ANY" | "NONE"`)
+    - `"NONE"`: Disables all tools (Wins over other hooks).
+    - `"ANY"`: Forces at least one tool call.
+  - `hookSpecificOutput.toolConfig.allowedFunctionNames`: (`string[]`) Whitelist
+    of tool names.
+- **Union Strategy**: Multiple hooks' whitelists are **combined**.
+- **Limitations**: Does **not** support `decision`, `continue`, or
+  `systemMessage`.
+
+### `AfterModel`
+
+Fires immediately after an LLM response chunk is received. Used for real-time
+redaction or PII filtering.
+
+- **Input Fields**:
+  - `llm_request`: (`object`) The original request.
+  - `llm_response`: (`object`) The model's response (or a single chunk during
+    streaming).
+- **Relevant Output Fields**:
+  - `hookSpecificOutput.llm_response`: An object that **replaces** the model's
+    response chunk.
+  - `decision`: Set to `"deny"` to discard the response chunk and block the
+    turn.
+  - `continue`: Set to `false` to **kill the entire agent loop** immediately.
+- **Note on Streaming**: Fired for **every chunk** generated by the model.
+  Modifying the response only affects the current chunk.
+- **Exit Code 2 (Block Response)**: Aborts the turn and discards the model's
+  output. Uses `stderr` as the error message.
+
+---
+
+## Lifecycle & system hooks
+
+### `SessionStart`
+
+Fires on application startup, resuming a session, or after a `/clear` command.
+Used for loading initial context.
+
+- **Input fields**:
+  - `source`: (`"startup" | "resume" | "clear"`)
+- **Relevant output fields**:
+  - `hookSpecificOutput.additionalContext`: (`string`)
+    - **Interactive**: Injected as the first turn in history.
+    - **Non-interactive**: Prepended to the user's prompt.
+  - `systemMessage`: Shown at the start of the session.
+- **Advisory only**: `continue` and `decision` fields are **ignored**. Startup
+  is never blocked.
+
+### `SessionEnd`
+
+Fires when the CLI exits or a session is cleared. Used for cleanup or final
+telemetry.
+
+- **Input Fields**:
+  - `reason`: (`"exit" | "clear" | "logout" | "prompt_input_exit" | "other"`)
+- **Relevant Output Fields**:
+  - `systemMessage`: Displayed to the user during shutdown.
+- **Best Effort**: The CLI **will not wait** for this hook to complete and
+  ignores all flow-control fields (`continue`, `decision`).
+
+### `Notification`
+
+Fires when the CLI emits a system alert (e.g., Tool Permissions). Used for
+external logging or cross-platform alerts.
+
+- **Input Fields**:
+  - `notification_type`: (`"ToolPermission"`)
+  - `message`: Summary of the alert.
+  - `details`: JSON object with alert-specific metadata (e.g., tool name, file
+    path).
+- **Relevant Output Fields**:
+  - `systemMessage`: Displayed alongside the system alert.
+- **Observability Only**: This hook **cannot** block alerts or grant permissions
+  automatically. Flow-control fields are ignored.
+
+### `PreCompress`
+
+Fires before the CLI summarizes history to save tokens. Used for logging or
+state saving.
+
+- **Input Fields**:
+  - `trigger`: (`"auto" | "manual"`)
+- **Relevant Output Fields**:
+  - `systemMessage`: Displayed to the user before compression.
+- **Advisory Only**: Fired asynchronously. It **cannot** block or modify the
+  compression process. Flow-control fields are ignored.

 ## Stable Model API
 
-Gemini CLI uses a decoupled format for model interactions to ensure hooks remain
-stable even if the underlying Gemini SDK changes.
+Gemini CLI uses these structures to ensure hooks don't break across SDK updates.
 
-### `LLMRequest` Object
-
-Used in `BeforeModel` and `BeforeToolSelection`.
-
-> 💡 **Note**: In v1, model hooks are primarily text-focused. Non-text parts
-> (like images or function calls) provided in the `content` array will be
-> simplified to their string representation by the translator.
+**LLMRequest**:
 
 ```typescript
 {
   "model": string,
   "messages": Array<{
     "role": "user" | "model" | "system",
-    "content": string | Array<{ "type": string, [key: string]: any }>
+    "content": string // Non-text parts are filtered out for hooks
   }>,
-  "config"?: {
-    "temperature"?: number,
-    "maxOutputTokens"?: number,
-    "topP"?: number,
-    "topK"?: number
-  },
-  "toolConfig"?: {
-    "mode"?: "AUTO" | "ANY" | "NONE",
-    "allowedFunctionNames"?: string[]
-  }
+  "config": { "temperature": number, ... },
+  "toolConfig": { "mode": string, "allowedFunctionNames": string[] }
 }
+
 ```
 
-### `LLMResponse` Object
-
-Used in `AfterModel` and as a synthetic response in `BeforeModel`.
+**LLMResponse**:
 
 ```typescript
 {
-  "text"?: string,
   "candidates": Array<{
-    "content": {
-      "role": "model",
-      "parts": string[]
-    },
-    "finishReason"?: "STOP" | "MAX_TOKENS" | "SAFETY" | "RECITATION" | "OTHER",
-    "index"?: number,
-    "safetyRatings"?: Array<{
-      "category": string,
-      "probability": string,
-      "blocked"?: boolean
-    }>
+    "content": { "role": "model", "parts": string[] },
+    "finishReason": string
   }>,
-  "usageMetadata"?: {
-    "promptTokenCount"?: number,
-    "candidatesTokenCount"?: number,
-    "totalTokenCount"?: number
-  }
+  "usageMetadata": { "totalTokenCount": number }
 }

-# Welcome to Gemini CLI documentation
+# Gemini CLI documentation
 
-This documentation provides a comprehensive guide to installing, using, and
-developing Gemini CLI, a tool that lets you interact with Gemini models through
-a command-line interface.
+Gemini CLI is an open-source AI agent that brings the power of Gemini directly
+into your terminal. It is designed to be a terminal-first, extensible, and
+powerful tool for developers, engineers, SREs, and beyond.
 
-## Gemini CLI overview
+Gemini CLI integrates with your local environment. It can read and edit files,
+execute shell commands, and search the web, all while maintaining your project
+context.
 
-Gemini CLI brings the capabilities of Gemini models to your terminal in an
-interactive Read-Eval-Print Loop (REPL) environment. Gemini CLI consists of a
-client-side application (`packages/cli`) that communicates with a local server
-(`packages/core`), which in turn manages requests to the Gemini API and its AI
-models. Gemini CLI also contains a variety of tools for tasks such as performing
-file system operations, running shells, and web fetching, which are managed by
-`packages/core`.

@@ -144,6 +144,48 @@ A significant drop in the pass rate for a `USUALLY_PASSES` test—even if it
 doesn't drop to 0%—often indicates that a recent change to a system prompt or
 tool definition has made the model's behavior less reliable.
 
-You may be able to investigate the regression using Gemini CLI by giving it the
-link to the runs before and after the change and the name of the test and asking
-it to investigate what changes may have impacted the test.
+## Fixing Evaluations
+
+If an evaluation is failing or has a regressed pass rate, you can use the
+`/fix-behavioral-eval` command within Gemini CLI to help investigate and fix the
+issue.
+
+### `/fix-behavioral-eval`
+
+This command is designed to automate the investigation and fixing process for
+failing evaluations. It will:
+
+1.  **Investigate**: Fetch the latest results from the nightly workflow using
+    the `gh` CLI, identify the failing test, and review test trajectory logs in
+    `evals/logs`.
+2.  **Fix**: Suggest and apply targeted fixes to the prompt or tool definitions.
+    It prioritizes minimal changes to `prompt.ts`, tool instructions, and
+    modules that contribute to the prompt. It generally tries to avoid changing
+    the test itself.
+3.  **Verify**: Re-run the test 3 times across multiple models (e.g., Gemini
+    3.0, Gemini 3 Flash, Gemini 2.5 Pro) to ensure stability and calculate a
+    success rate.
+4.  **Report**: Provide a summary of the success rate for each model and details
+    on the applied fixes.
+
+To use it, run:
+
+```bash
+gemini /fix-behavioral-eval
+```
+
+You can also provide a link to a specific GitHub Action run or the name of a
+specific test to focus the investigation:
+
+```bash
+gemini /fix-behavioral-eval https://github.com/google-gemini/gemini-cli/actions/runs/123456789
+```
+
+When investigating failures manually, you can also enable verbose agent logs by
+setting the `GEMINI_DEBUG_LOG_FILE` environment variable.
+
+It's highly recommended to manually review and/or ask the agent to iterate on
+any prompt changes, even if they pass all evals. The prompt should prefer
+positive traits ('do X') and resort to negative traits ('do not do X') only when
+unable to accomplish the goal with positive traits. Gemini is quite good at
+instrospecting on its prompt when asked the right questions.
