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

description = "Reviews a frontend PR or staged changes and automatically initiates a Pickle Fix loop for findings."
prompt = """
You are an expert Frontend 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.
* Avoid using `any` in tests; prefer proper types or `unknown` with
narrowing.
* 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. 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.
10. 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.
11. Summarize all actionable findings into a concise but comprehensive directive output this to frontend_review.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 coding 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" $ARGUMENTS
```
**CRITICAL**: Your request is to fix all findings in frontend_review.md
**Step 2: Execution (Management)**
After setup, read the output to find the path to `state.json`.
Read that state file.
You are now in the **Pickle Rick Manager Lifecycle**.
**The Lifecycle (IMMUTABLE LAWS):**
You **MUST** follow this sequence. You are **FORBIDDEN** from skipping steps or combining them.
Between each step, you **MUST** explicitly state what you are doing (e.g., "Moving to Breakdown phase...").
1. **PRD (Requirements)**:
* **Action**: Define requirements and scope.
* **Skill**: `activate_skill(name="prd-drafter")`
2. **Breakdown (Tickets)**:
* **Action**: Create the atomic ticket hierarchy.
* **Skill**: `activate_skill(name="ticket-manager")`
3. **The Loop (Orchestrate Mortys)**:
* **CRITICAL INSTRUCTION**: You are the **MANAGER**. You are **FORBIDDEN** from implementing code yourself.
* **FORBIDDEN SKILLS**: Do NOT use `code-researcher`, `implementation-planner`, or `code-implementer` directly in this phase.
* **Instruction**: Process tickets one by one. Do not stop until **ALL** tickets are 'Done'.
* **Action**: Pick the highest priority ticket that is NOT 'Done'.
* **Delegation**: Spawn a Worker (Morty) to handle the entire implementation lifecycle for this ticket.
* **Command**: `python3 "${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. Run tests/build (Check functionality)
* **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 `frontend_review.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.

Use this skill to review code. It supports both local changes (staged or working tree)
and remote Pull Requests (by ID or URL). It focuses on correctness, maintainability,
and adherence to project standards.

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

Use this skill for writing, reviewing, and editing documentation (`/docs`
directory or any .md file) for Gemini CLI.

# `docs-writer` skill instructions
As an expert technical writer and editor for the Gemini CLI project, your goal
is to produce and refine documentation that is accurate, clear, consistent, and
easy for users to understand. You must adhere to the documentation contribution
process outlined in `CONTRIBUTING.md`.
## Step 1: Understand the goal and create a plan
1. **Clarify the request:** Fully understand the user's documentation request.
Identify the core feature, command, or concept that needs work.
2. **Differentiate the task:** Determine if the request is primarily for
**writing** new content or **editing** existing content. If the request is
ambiguous (e.g., "fix the docs"), ask the user for clarification.
3. **Formulate a plan:** Create a clear, step-by-step plan for the required
changes.
## Step 2: Investigate and gather information
1. **Read the code:** Thoroughly examine the relevant codebase, primarily
within
the `packages/` directory, to ensure your work is backed by the
implementation and to identify any gaps.
2. **Identify files:** Locate the specific documentation files in the `docs/`
directory that need to be modified. Always read the latest version of a file
before you begin work.
3. **Check for connections:** Consider related documentation. If you change a
command's behavior, check for other pages that reference it. If you add a new
page, check if `docs/sidebar.json` needs to be updated. Make sure all
links are up to date.
## Step 3: Write or edit the documentation
1. **Follow the style guide:** Adhere to the rules in
`references/style-guide.md`. Read this file to understand the project's
documentation standards.
2. Ensure the new documentation accurately reflects the features in the code.
3. **Use `replace` and `write_file`:** Use file system tools to apply your
planned changes. For small edits, `replace` is preferred. For new files or
large rewrites, `write_file` is more appropriate.
### Sub-step: Editing existing documentation (as clarified in Step 1)
- **Gaps:** Identify areas where the documentation is incomplete or no longer
reflects existing code.
- **Tone:** Ensure the tone is active and engaging, not passive.
- **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.
## Step 4: Verify and finalize
1. **Review your work:** After making changes, re-read the files to ensure the
documentation is well-formatted, and the content is correct based on
existing code.
2. **Link verification:** Verify the validity of all links in the new content.
Verify the validity of existing links leading to the page with the new
content or deleted content.
2. **Offer to run npm format:** Once all changes are complete, offer to run the
project's formatting script to ensure consistency by proposing the command:
`npm run format`

# Documentation style guide
## I. Core principles
1. **Clarity:** Write for easy understanding. Prioritize clear, direct, and
simple language.
2. **Consistency:** Use consistent terminology, formatting, and style
throughout the documentation.
3. **Accuracy:** Ensure all information is technically correct and up-to-date.
4. **Accessibility:** Design documentation to be usable by everyone. Focus on
semantic structure, clear link text, and image alternatives.
5. **Global audience:** Write in standard US English. Avoid slang, idioms, and
cultural references.
6. **Prescriptive:** Guide the reader by recommending specific actions and
paths, especially for complex tasks.
## II. Voice and tone
- **Professional yet friendly:** Maintain a helpful, knowledgeable, and
conversational tone without being frivolous.
- **Direct:** Get straight to the point. Keep paragraphs short and focused.
- **Second person:** Address the reader as "you."
- **Present tense:** Use the present tense to describe functionality (e.g., "The
API returns a JSON object.").
- **Avoid:** Jargon, slang, marketing hype, and overly casual language.
## III. Language and grammar
- **Active voice:** Prefer active voice over passive voice.
- _Example:_ "The system sends a notification." (Not: "A notification is sent
by the system.")
- **Contractions:** Use common contractions (e.g., "don't," "it's") to maintain
a natural tone.
- **Simple vocabulary:** Use common words. Define technical terms when
necessary.
- **Conciseness:** Keep sentences short and focused.
- **"Please":** Avoid using the word "please."
## IV. Procedures and steps
- Start each step with an imperative verb (e.g., "Connect to the database").
- Number steps sequentially.
- Introduce lists of steps with a complete sentence.
- Put conditions before instructions, not after.
- Provide clear context for where the action takes place (e.g., "In the
administration console...").
- Indicate optional steps clearly (e.g., "Optional: ...").
## V. Formatting and punctuation
- **Text wrap:** Wrap all text at 80 characters, with exceptions for long links
or tables.
- **Headings, titles, and bold text:** Use sentence case. Structure headings
hierarchically.
- **Lists:** Use numbered lists for sequential steps and bulleted lists for all
other lists. Keep list items parallel in structure.
- **Serial comma:** Use the serial comma (e.g., "one, two, and three").
- **Punctuation:** Use standard American punctuation. Place periods inside
quotation marks.
- **Dates:** Use unambiguous date formatting (e.g., "January 22, 2026").
## VI. UI, code, and links
- **UI elements:** Put UI elements in **bold**. Focus on the task when
discussing interaction.
- **Code:** Use `code font` for filenames, code snippets, commands, and API
elements. Use code blocks for multi-line samples.
- **Links:** Use descriptive link text that indicates what the link leads to.
Avoid "click here."
## VII. Word choice and terminology
- **Consistent naming:** Use product and feature names consistently. Always
refer to Gemini CLI as `Gemini CLI`, never `the Gemini CLI`.
- **Specific verbs:** Use precise verbs.
- **Avoid:**
- Latin abbreviations (e.g., use "for example" instead of "e.g.").
- Placeholder names like "foo" and "bar" in examples; use meaningful names
instead.
- Anthropomorphism (e.g., "The server thinks...").
- "Should": Be clear about requirements ("must") vs. recommendations ("we
recommend").
## VIII. Files and media
- **Filenames:** Use lowercase letters, separate words with hyphens (-), and use
standard ASCII characters.
- **Images:** Provide descriptive alt text for all images. Provide
high-resolution or vector images when practical.
## IX. Accessibility quick check
- Provide descriptive alt text for images.
- Ensure link text makes sense out of context.
- Use semantic HTML elements correctly (headings, lists, tables).

# Gemini CLI Project Context
## Building and running
Gemini CLI is an open-source AI agent that brings the power of Gemini directly
into the terminal. It is designed to be a terminal-first, extensible, and
powerful tool for developers.
Before submitting any changes, it is crucial to validate them by running the
full preflight check. This command will build the repository, run all tests,
check for type errors, and lint the code.
## Project Overview
To run the full suite of checks, execute the following command:
- **Purpose:** Provide a seamless terminal interface for Gemini models,
supporting code understanding, generation, automation, and integration via MCP
(Model Context Protocol).
- **Main Technologies:**
- **Runtime:** Node.js (>=20.0.0, recommended ~20.19.0 for development)
- **Language:** TypeScript
- **UI Framework:** React (using [Ink](https://github.com/vadimdemedes/ink)
for CLI rendering)
- **Testing:** Vitest
- **Bundling:** esbuild
- **Linting/Formatting:** ESLint, Prettier
- **Architecture:** Monorepo structure using npm workspaces.
- `packages/cli`: User-facing terminal UI, input processing, and display
rendering.
- `packages/core`: Backend logic, Gemini API orchestration, prompt
construction, and tool execution.
- `packages/core/src/tools/`: Built-in tools for file system, shell, and web
operations.
- `packages/a2a-server`: Experimental Agent-to-Agent server.
- `packages/vscode-ide-companion`: VS Code extension pairing with the CLI.
```bash
npm run preflight
```
## Building and Running
This single command ensures that your changes meet all the quality gates of the
project. While you can run the individual steps (`build`, `test`, `typecheck`,
`lint`) separately, it is highly recommended to use `npm run preflight` to
ensure a comprehensive validation.
- **Install Dependencies:** `npm install`
- **Build All:** `npm run build:all` (Builds packages, sandbox, and VS Code
companion)
- **Build Packages:** `npm run build`
- **Run in Development:** `npm run start`
- **Run in Debug Mode:** `npm run debug` (Enables Node.js inspector)
- **Bundle Project:** `npm run bundle`
- **Clean Artifacts:** `npm run clean`
## Running Tests in Workspaces\*\*: To run a specific test file within a
## Testing and Quality
workspace, use the command:
`npm test -w <workspace-name> -- <path/to/test-file.test.ts>`. **CRITICAL**: The
`<path/to/test-file.test.ts>` MUST be relative to the workspace directory root,
NOT the project root.
- **Test Commands:**
- **Unit (All):** `npm run test`
- **Integration (E2E):** `npm run test:e2e`
- **Workspace-Specific:** `npm test -w <pkg> -- <path>` (Note: `<path>` must
be relative to the workspace root, e.g.,
`-w @google/gemini-cli-core -- src/routing/modelRouterService.test.ts`)
- **Full Validation:** `npm run preflight` (Heaviest check; runs clean, install,
build, lint, type check, and tests. Recommended before submitting PRs.)
- **Individual Checks:** `npm run lint` / `npm run format` / `npm run typecheck`
- _Example (Core package)_:
`npm test -w @google/gemini-cli-core -- src/routing/modelRouterService.test.ts`
- _Common workspaces_: `@google/gemini-cli`, `@google/gemini-cli-core`.
## Development Conventions
## Writing Tests
- **Contributions:** Follow the process outlined in `CONTRIBUTING.md`. Requires
signing the Google CLA.
- **Pull Requests:** Keep PRs small, focused, and linked to an existing issue.
- **Commit Messages:** Follow the
[Conventional Commits](https://www.conventionalcommits.org/) standard.
- **Coding Style:** Adhere to existing patterns in `packages/cli` (React/Ink)
and `packages/core` (Backend logic).
- **Imports:** Use specific imports and avoid restricted relative imports
between packages (enforced by ESLint).
This project uses **Vitest** as its primary testing framework. When writing
tests, aim to follow existing patterns. Key conventions include:
## Testing Conventions
### Test Structure and Framework
- **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', '')`.
- **Framework**: All tests are written using Vitest (`describe`, `it`, `expect`,
`vi`).
- **File Location**: Test files (`*.test.ts` for logic, `*.test.tsx` for React
components) are co-located with the source files they test.
- **Configuration**: Test environments are defined in `vitest.config.ts` files.
- **Setup/Teardown**: Use `beforeEach` and `afterEach`. Commonly,
`vi.resetAllMocks()` is called in `beforeEach` and `vi.restoreAllMocks()` in
`afterEach`.
## Documentation
### Mocking (`vi` from Vitest)
- Suggest documentation updates when code changes render existing documentation
obsolete or incomplete.
- Located in the `docs/` directory.
- Use the `docs-writer` skill.
- **ES Modules**: Mock with
`vi.mock('module-name', async (importOriginal) => { ... })`. Use
`importOriginal` for selective mocking.
- _Example_:
`vi.mock('os', async (importOriginal) => { const actual = await importOriginal(); return { ...actual, homedir: vi.fn() }; });`
- **Mocking Order**: For critical dependencies (e.g., `os`, `fs`) that affect
module-level constants, place `vi.mock` at the _very top_ of the test file,
before other imports.
- **Hoisting**: Use `const myMock = vi.hoisted(() => vi.fn());` if a mock
function needs to be defined before its use in a `vi.mock` factory.
- **Mock Functions**: Create with `vi.fn()`. Define behavior with
`mockImplementation()`, `mockResolvedValue()`, or `mockRejectedValue()`.
- **Spying**: Use `vi.spyOn(object, 'methodName')`. Restore spies with
`mockRestore()` in `afterEach`.
### Commonly Mocked Modules
- **Node.js built-ins**: `fs`, `fs/promises`, `os` (especially `os.homedir()`),
`path`, `child_process` (`execSync`, `spawn`).
- **External SDKs**: `@google/genai`, `@modelcontextprotocol/sdk`.
- **Internal Project Modules**: Dependencies from other project packages are
often mocked.
### React Component Testing (CLI UI - Ink)
- Use `render()` from `ink-testing-library`.
- Assert output with `lastFrame()`.
- Wrap components in necessary `Context.Provider`s.
- Mock custom React hooks and complex child components using `vi.mock()`.
### Asynchronous Testing
- Use `async/await`.
- For timers, use `vi.useFakeTimers()`, `vi.advanceTimersByTimeAsync()`,
`vi.runAllTimersAsync()`.
- Test promise rejections with `await expect(promise).rejects.toThrow(...)`.
### General Guidance
- When adding tests, first examine existing tests to understand and conform to
established conventions.
- Pay close attention to the mocks at the top of existing test files; they
reveal critical dependencies and how they are managed in a test environment.

## JavaScript/TypeScript
When contributing to this React, Node, and TypeScript codebase, please
prioritize the use of plain JavaScript objects with accompanying TypeScript
interface or type declarations over JavaScript class syntax. This approach
offers significant advantages, especially concerning interoperability with React
and overall code maintainability.
### Preferring Plain Objects over Classes
JavaScript classes, by their nature, are designed to encapsulate internal state
and behavior. While this can be useful in some object-oriented paradigms, it
often introduces unnecessary complexity and friction when working with React's
component-based architecture. Here's why plain objects are preferred:
- Seamless React Integration: React components thrive on explicit props and
state management. Classes' tendency to store internal state directly within
instances can make prop and state propagation harder to reason about and
maintain. Plain objects, on the other hand, are inherently immutable (when
used thoughtfully) and can be easily passed as props, simplifying data flow
and reducing unexpected side effects.
- Reduced Boilerplate and Increased Conciseness: Classes often promote the use
of constructors, this binding, getters, setters, and other boilerplate that
can unnecessarily bloat code. TypeScript interface and type declarations
provide powerful static type checking without the runtime overhead or
verbosity of class definitions. This allows for more succinct and readable
code, aligning with JavaScript's strengths in functional programming.
- Enhanced Readability and Predictability: Plain objects, especially when their
structure is clearly defined by TypeScript interfaces, are often easier to
read and understand. Their properties are directly accessible, and there's no
hidden internal state or complex inheritance chains to navigate. This
predictability leads to fewer bugs and a more maintainable codebase.
- Simplified Immutability: While not strictly enforced, plain objects encourage
an immutable approach to data. When you need to modify an object, you
typically create a new one with the desired changes, rather than mutating the
original. This pattern aligns perfectly with React's reconciliation process
and helps prevent subtle bugs related to shared mutable state.
- Better Serialization and Deserialization: Plain JavaScript objects are
naturally easy to serialize to JSON and deserialize back, which is a common
requirement in web development (e.g., for API communication or local storage).
Classes, with their methods and prototypes, can complicate this process.
### Embracing ES Module Syntax for Encapsulation
Rather than relying on Java-esque private or public class members, which can be
verbose and sometimes limit flexibility, we strongly prefer leveraging ES module
syntax (`import`/`export`) for encapsulating private and public APIs.
- Clearer Public API Definition: With ES modules, anything that is exported is
part of the public API of that module, while anything not exported is
inherently private to that module. This provides a very clear and explicit way
to define what parts of your code are meant to be consumed by other modules.
- Enhanced Testability (Without Exposing Internals): By default, unexported
functions or variables are not accessible from outside the module. This
encourages you to test the public API of your modules, rather than their
internal implementation details. If you find yourself needing to spy on or
stub an unexported function for testing purposes, it's often a "code smell"
indicating that the function might be a good candidate for extraction into its
own separate, testable module with a well-defined public API. This promotes a
more robust and maintainable testing strategy.
- Reduced Coupling: Explicitly defined module boundaries through import/export
help reduce coupling between different parts of your codebase. This makes it
easier to refactor, debug, and understand individual components in isolation.
### Avoiding `any` Types and Type Assertions; Preferring `unknown`
TypeScript's power lies in its ability to provide static type checking, catching
potential errors before your code runs. To fully leverage this, it's crucial to
avoid the `any` type and be judicious with type assertions.
- **The Dangers of `any`**: Using any effectively opts out of TypeScript's type
checking for that particular variable or expression. While it might seem
convenient in the short term, it introduces significant risks:
- **Loss of Type Safety**: You lose all the benefits of type checking, making
it easy to introduce runtime errors that TypeScript would otherwise have
caught.
- **Reduced Readability and Maintainability**: Code with `any` types is harder
to understand and maintain, as the expected type of data is no longer
explicitly defined.
- **Masking Underlying Issues**: Often, the need for any indicates a deeper
problem in the design of your code or the way you're interacting with
external libraries. It's a sign that you might need to refine your types or
refactor your code.
- **Preferring `unknown` over `any`**: When you absolutely cannot determine the
type of a value at compile time, and you're tempted to reach for any, consider
using unknown instead. unknown is a type-safe counterpart to any. While a
variable of type unknown can hold any value, you must perform type narrowing
(e.g., using typeof or instanceof checks, or a type assertion) before you can
perform any operations on it. This forces you to handle the unknown type
explicitly, preventing accidental runtime errors.
```ts
function processValue(value: unknown) {
if (typeof value === 'string') {
// value is now safely a string
console.log(value.toUpperCase());
} else if (typeof value === 'number') {
// value is now safely a number
console.log(value * 2);
}
// Without narrowing, you cannot access properties or methods on 'value'
// console.log(value.someProperty); // Error: Object is of type 'unknown'.
}
```
- **Type Assertions (`as Type`) - Use with Caution**: Type assertions tell the
TypeScript compiler, "Trust me, I know what I'm doing; this is definitely of
this type." While there are legitimate use cases (e.g., when dealing with
external libraries that don't have perfect type definitions, or when you have
more information than the compiler), they should be used sparingly and with
extreme caution.
- **Bypassing Type Checking**: Like `any`, type assertions bypass TypeScript's
safety checks. If your assertion is incorrect, you introduce a runtime error
that TypeScript would not have warned you about.
- **Code Smell in Testing**: A common scenario where `any` or type assertions
might be tempting is when trying to test "private" implementation details
(e.g., spying on or stubbing an unexported function within a module). This
is a strong indication of a "code smell" in your testing strategy and
potentially your code structure. Instead of trying to force access to
private internals, consider whether those internal details should be
refactored into a separate module with a well-defined public API. This makes
them inherently testable without compromising encapsulation.
### Type narrowing `switch` clauses
Use the `checkExhaustive` helper in the default clause of a switch statement.
This will ensure that all of the possible options within the value or
enumeration are used.
This helper method can be found in `packages/cli/src/utils/checks.ts`
### Embracing JavaScript's Array Operators
To further enhance code cleanliness and promote safe functional programming
practices, leverage JavaScript's rich set of array operators as much as
possible. Methods like `.map()`, `.filter()`, `.reduce()`, `.slice()`,
`.sort()`, and others are incredibly powerful for transforming and manipulating
data collections in an immutable and declarative way.
Using these operators:
- Promotes Immutability: Most array operators return new arrays, leaving the
original array untouched. This functional approach helps prevent unintended
side effects and makes your code more predictable.
- Improves Readability: Chaining array operators often lead to more concise and
expressive code than traditional for loops or imperative logic. The intent of
the operation is clear at a glance.
- Facilitates Functional Programming: These operators are cornerstones of
functional programming, encouraging the creation of pure functions that take
inputs and produce outputs without causing side effects. This paradigm is
highly beneficial for writing robust and testable code that pairs well with
React.
By consistently applying these principles, we can maintain a codebase that is
not only efficient and performant but also a joy to work with, both now and in
the future.
## React (mirrored and adjusted from [react-mcp-server](https://github.com/facebook/react/blob/4448b18760d867f9e009e810571e7a3b8930bb19/compiler/packages/react-mcp-server/src/index.ts#L376C1-L441C94))
### Role
You are a React assistant that helps users write more efficient and optimizable
React code. You specialize in identifying patterns that enable React Compiler to
automatically apply optimizations, reducing unnecessary re-renders and improving
application performance.
### Follow these guidelines in all code you produce and suggest
Use functional components with Hooks: Do not generate class components or use
old lifecycle methods. Manage state with useState or useReducer, and side
effects with useEffect (or related Hooks). Always prefer functions and Hooks for
any new component logic.
Keep components pure and side-effect-free during rendering: Do not produce code
that performs side effects (like subscriptions, network requests, or modifying
external variables) directly inside the component's function body. Such actions
should be wrapped in useEffect or performed in event handlers. Ensure your
render logic is a pure function of props and state.
Respect one-way data flow: Pass data down through props and avoid any global
mutations. If two components need to share data, lift that state up to a common
parent or use React Context, rather than trying to sync local state or use
external variables.
Never mutate state directly: Always generate code that updates state immutably.
For example, use spread syntax or other methods to create new objects/arrays
when updating state. Do not use assignments like state.someValue = ... or array
mutations like array.push() on state variables. Use the state setter (setState
from useState, etc.) to update state.
Accurately use useEffect and other effect Hooks: whenever you think you could
useEffect, think and reason harder to avoid it. useEffect is primarily only used
for synchronization, for example synchronizing React with some external state.
IMPORTANT - Don't setState (the 2nd value returned by useState) within a
useEffect as that will degrade performance. When writing effects, include all
necessary dependencies in the dependency array. Do not suppress ESLint rules or
omit dependencies that the effect's code uses. Structure the effect callbacks to
handle changing values properly (e.g., update subscriptions on prop changes,
clean up on unmount or dependency change). If a piece of logic should only run
in response to a user action (like a form submission or button click), put that
logic in an event handler, not in a useEffect. Where possible, useEffects should
return a cleanup function.
Follow the Rules of Hooks: Ensure that any Hooks (useState, useEffect,
useContext, custom Hooks, etc.) are called unconditionally at the top level of
React function components or other Hooks. Do not generate code that calls Hooks
inside loops, conditional statements, or nested helper functions. Do not call
Hooks in non-component functions or outside the React component rendering
context.
Use refs only when necessary: Avoid using useRef unless the task genuinely
requires it (such as focusing a control, managing an animation, or integrating
with a non-React library). Do not use refs to store application state that
should be reactive. If you do use refs, never write to or read from ref.current
during the rendering of a component (except for initial setup like lazy
initialization). Any ref usage should not affect the rendered output directly.
Prefer composition and small components: Break down UI into small, reusable
components rather than writing large monolithic components. The code you
generate should promote clarity and reusability by composing components
together. Similarly, abstract repetitive logic into custom Hooks when
appropriate to avoid duplicating code.
Optimize for concurrency: Assume React may render your components multiple times
for scheduling purposes (especially in development with Strict Mode). Write code
that remains correct even if the component function runs more than once. For
instance, avoid side effects in the component body and use functional state
updates (e.g., setCount(c => c + 1)) when updating state based on previous state
to prevent race conditions. Always include cleanup functions in effects that
subscribe to external resources. Don't write useEffects for "do this when this
changes" side effects. This ensures your generated code will work with React's
concurrent rendering features without issues.
Optimize to reduce network waterfalls - Use parallel data fetching wherever
possible (e.g., start multiple requests at once rather than one after another).
Leverage Suspense for data loading and keep requests co-located with the
component that needs the data. In a server-centric approach, fetch related data
together in a single request on the server side (using Server Components, for
example) to reduce round trips. Also, consider using caching layers or global
fetch management to avoid repeating identical requests.
Rely on React Compiler - useMemo, useCallback, and React.memo can be omitted if
React Compiler is enabled. Avoid premature optimization with manual memoization.
Instead, focus on writing clear, simple components with direct data flow and
side-effect-free render functions. Let the React Compiler handle tree-shaking,
inlining, and other performance enhancements to keep your code base simpler and
more maintainable.
Design for a good user experience - Provide clear, minimal, and non-blocking UI
states. When data is loading, show lightweight placeholders (e.g., skeleton
screens) rather than intrusive spinners everywhere. Handle errors gracefully
with a dedicated error boundary or a friendly inline message. Where possible,
render partial data as it becomes available rather than making the user wait for
everything. Suspense allows you to declare the loading states in your component
tree in a natural way, preventing “flash” states and improving perceived
performance.
### Process
1. Analyze the user's code for optimization opportunities:
- Check for React anti-patterns that prevent compiler optimization
- Look for component structure issues that limit compiler effectiveness
- Think about each suggestion you are making and consult React docs for best
practices
2. Provide actionable guidance:
- Explain specific code changes with clear reasoning
- Show before/after examples when suggesting changes
- Only suggest changes that meaningfully improve optimization potential
### Optimization Guidelines
- State updates should be structured to enable granular updates
- Side effects should be isolated and dependencies clearly defined
## Documentation guidelines
When working in the `/docs` directory, follow the guidelines in this section:
- **Role:** You are an expert technical writer and AI assistant for contributors
to Gemini CLI. Produce professional, accurate, and consistent documentation to
guide users of Gemini CLI.
- **Technical Accuracy:** Do not invent facts, commands, code, API names, or
output. All technical information specific to Gemini CLI must be based on code
found within this directory and its subdirectories.
- **Style Authority:** Your source for writing guidance and style is the
"Documentation contribution process" section in the root directory's
`CONTRIBUTING.md` file, as well as any guidelines provided this section.
- **Information Architecture Consideration:** Before proposing documentation
changes, consider the information architecture. If a change adds significant
new content to existing documents, evaluate if creating a new, more focused
page or changes to `sidebar.json` would provide a better user experience.
- **Proactive User Consideration:** The user experience should be a primary
concern when making changes to documentation. Aim to fill gaps in existing
knowledge whenever possible while keeping documentation concise and easy for
users to understand. If changes might hinder user understanding or
accessibility, proactively raise these concerns and propose alternatives.
## Comments policy
Only write high-value comments if at all. Avoid talking to the user through
comments.
## Logging and Error Handling
- **Avoid Console Statements:** Do not use `console.log`, `console.error`, or
similar methods directly.
- **Non-User-Facing Logs:** For developer-facing debug messages, use
`debugLogger` (from `@google/gemini-cli-core`).
- **User-Facing Feedback:** To surface errors or warnings to the user, use
`coreEvents.emitFeedback` (from `@google/gemini-cli-core`).
## General requirements
- If there is something you do not understand or is ambiguous, seek confirmation
or clarification from the user before making changes based on assumptions.
- Use hyphens instead of underscores in flag names (e.g. `my-flag` instead of
`my_flag`).
- Always refer to Gemini CLI as `Gemini CLI`, never `the Gemini CLI`.

# Remote Subagents (experimental)
Gemini CLI supports connecting to remote subagents using the Agent-to-Agent
(A2A) protocol. This allows Gemini CLI to interact with other agents, expanding
its capabilities by delegating tasks to remote services.
Gemini CLI can connect to any compliant A2A agent. You can find samples of A2A
agents in the following repositories:
- [ADK Samples (Python)](https://github.com/google/adk-samples/tree/main/python)
- [ADK Python Contributing Samples](https://github.com/google/adk-python/tree/main/contributing/samples)
> **Note: Remote subagents are currently an experimental feature.**
## Configuration
To use remote subagents, you must explicitly enable them in your
`settings.json`:
```json
{
"experimental": {
"enableAgents": true
}
}
```
## Defining remote subagents
Remote subagents 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)
### Configuration schema
| Field | Type | Required | Description |
| :--------------- | :----- | :------- | :------------------------------------------------------------------------------------------------------------- |
| `kind` | string | Yes | Must be `remote`. |
| `name` | string | Yes | A unique name for the agent. Must be a valid slug (lowercase letters, numbers, hyphens, and underscores only). |
| `agent_card_url` | string | Yes | The URL to the agent's A2A card endpoint. |
### Single-subagent example
```markdown
---
kind: remote
name: my-remote-agent
agent_card_url: https://example.com/agent-card
---
```
### Multi-subagent example
The loader explicitly supports multiple remote subagents defined in a single
Markdown file.
```markdown
---
- kind: remote
name: remote-1
agent_card_url: https://example.com/1
- kind: remote
name: remote-2
agent_card_url: https://example.com/2
---
```
> **Note:** Mixed local and remote agents, or multiple local agents, are not
> supported in a single file; the list format is currently remote-only.
## Managing Subagents
Users can manage subagents using the following commands within the Gemini CLI:
- `/agents list`: Displays all available local and remote subagents.
- `/agents refresh`: Reloads the agent registry. Use this after adding or
modifying agent definition files.
- `/agents enable <agent_name>`: Enables a specific subagent.
- `/agents disable <agent_name>`: Disables a specific subagent.

> with configuring subagents.

# Sub-agents (experimental)
Sub-agents are specialized agents that operate within your main Gemini CLI
session. They are designed to handle specific, complex tasks—like deep codebase
analysis, documentation lookup, or domain-specific reasoning—without cluttering
the main agent's context or toolset.
> **Note: Sub-agents are currently an experimental feature.**
>
> To use custom sub-agents, you must explicitly enable them in your
> `settings.json`:
>
> ```json
> {
> "experimental": { "enableAgents": true }
> }
> ```
>
> **Warning:** Sub-agents currently operate in
> ["YOLO mode"](../get-started/configuration.md#command-line-arguments), meaning
> they may execute tools without individual user confirmation for each step.
> Proceed with caution when defining agents with powerful tools like
> `run_shell_command` or `write_file`.
## What are sub-agents?
Think of sub-agents as "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. The main agent only sees the final result, saving
tokens in your main conversation history.
Sub-agents are exposed to the main agent as a tool of the same name which
delegates to the sub-agent, when called. Once the sub-agent completes its task
(or fails), it reports back to the main agent with its findings (usually as a
text summary or structured report returned by the tool).
## Built-in sub-agents
Gemini CLI comes with powerful built-in sub-agents.
### Codebase Investigator
- **Name:** `codebase_investigator`
- **Purpose:** Deep analysis of the codebase, reverse engineering, and
understanding 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:** 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.
## Creating custom sub-agents
You can create your own sub-agents to automate specific workflows or enforce
specific personas.
### Prerequisites
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
- search_file_content
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. |
| `timeout_mins` | number | No | Maximum execution time in minutes. |
### Optimizing your sub-agent
The main agent system prompt contains language that encourages use of an expert
sub-agent when one is available for the task at hand. 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:

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)
Gemini CLI can also delegate tasks to remote subagents using the Agent-to-Agent
(A2A) protocol.
See the [Remote Subagents documentation](/docs/core/remote-agents) for detailed
configuration and usage instructions.
## Extension sub-agents
Extensions can bundle and distribute sub-agents. See the
[Extensions documentation](../extensions/index.md#sub-agents) for details on how
to package agents within an extension.

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

# Gemini CLI extensions
Gemini CLI extensions package prompts, MCP servers, custom commands, hooks,
sub-agents, and agent skills into a familiar and user-friendly format. With
extensions, you can expand the capabilities of Gemini CLI and share those
capabilities with others. They are designed to be easily installable and
shareable.
_This documentation is up-to-date with the v0.4.0 release._
Gemini CLI extensions package prompts, MCP servers, Agent Skills, and custom
commands into a familiar and user-friendly format. With extensions, you can
expand the capabilities of Gemini CLI and share those capabilities with others.
They're designed to be easily installable and shareable.
To see examples of extensions, you can browse a gallery of
[Gemini CLI extensions](https://geminicli.com/extensions/browse/).
## Managing extensions
See [getting started docs](getting-started-extensions.md) for a guide on
creating your first extension.
You can verify your installed extensions and their status using the interactive
command:
See [releasing docs](extension-releasing.md) for an advanced guide on setting up
GitHub releases.
```bash
/extensions list
## Extension management
We offer a suite of extension management tools using `gemini extensions`
commands.
Note that these commands are not supported from within the CLI, although you can
list installed extensions using the `/extensions list` subcommand.
Note that all of these commands will only be reflected in active CLI sessions on
restart.
### Installing an extension
You can install an extension using `gemini extensions install` with either a
GitHub URL or a local path.
Note that we create a copy of the installed extension, so you will need to run
`gemini extensions update` to pull in changes from both locally-defined
extensions and those on GitHub.
NOTE: If you are installing an extension from GitHub, you'll need to have `git`
installed on your machine. See
[git installation instructions](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
for help.
```
gemini extensions install <source> [--ref <ref>] [--auto-update] [--pre-release] [--consent]
```
or in noninteractive mode:
- `<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.
```bash
### 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:
```
gemini extensions list
```
## Installation
and you can update a given setting using:
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
```
gemini extensions config <extension name> [setting name] [--scope <scope>]
```
## Next steps
- `--scope`: The scope to set the setting in (`user` or `workspace`). This is
optional and will default to `user`.
- [Writing extensions](writing-extensions.md): Learn how to create your first
extension.
- [Extensions reference](reference.md): Deeply understand the extension format,
commands, and configuration.
- [Best practices](best-practices.md): Learn strategies for building great
extensions.
- [Extensions releasing](releasing.md): Learn how to share your extensions with
the world.
### 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${/}server.js"]`.
**Supported variables:**
| variable | description |
| -------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `${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). |

### Use appropriate events
Choose hook events that match your use case to avoid unnecessary execution.
`AfterAgent` fires once per agent loop completion, while `AfterModel` fires
after every LLM call (potentially multiple times per loop):
- **`AfterAgent`**: Fires **once** per turn after the model finishes its final
response. Use this for quality validation (Retries) or final logging.
- **`AfterModel`**: Fires after **every chunk** of LLM output. Use this for
real-time redaction, PII filtering, or monitoring output as it streams.

performance.

### Optimize JSON parsing
For large inputs (like `AfterModel` receiving a large context), standard JSON
parsing can be slow. If you only need one field, consider streaming parsers or
lightweight extraction logic, though for most shell scripts `jq` is sufficient.
For large inputs, use streaming JSON parsers to avoid loading everything into
memory:
```javascript
// Standard approach: parse entire input
const input = JSON.parse(await readStdin());
const content = input.tool_input.content;
// For very large inputs: stream and extract only needed fields
const { createReadStream } = require('fs');
const JSONStream = require('JSONStream');
const stream = createReadStream(0).pipe(JSONStream.parse('tool_input.content'));
let content = '';
stream.on('data', (chunk) => {
content += chunk;
});
```
## Debugging
### The "Strict JSON" rule
The most common cause of hook failure is "polluting" the standard output.
- **stdout** is for **JSON only**.
- **stderr** is for **logs and text**.
**Good:**
```bash
#!/bin/bash
echo "Starting check..." >&2 # <--- Redirect to stderr
echo '{"decision": "allow"}'

### Check exit codes
Gemini CLI uses exit codes for high-level flow control:
- **Exit 0 (Success)**: The hook ran successfully. The CLI parses `stdout` for
JSON decisions.
- **Exit 2 (System Block)**: A critical block occurred. `stderr` is used as the
reason.
- For **Agent/Model** events, this aborts the turn.
- For **Tool** events, this blocks the tool but allows the agent to continue.
- For **AfterAgent**, this triggers an automatic retry turn.

## 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": [
{
"name": "quick-check",
"command": "./quick-validation.sh",
"timeout": 1000
}
]
},
{
"matcher": "write_file",
"hooks": [
{
"name": "deep-check",
"command": "./deep-analysis.sh",
"timeout": 30000
}
]
}
]
}
}
```
### 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: ${userInput}` }));
```
**Check for binary data or control characters:**
```javascript
function sanitizeForJSON(str) {
return str.replace(/[\x00-\x1F\x7F-\x9F]/g, ''); // Remove control chars
}
const cleanContent = sanitizeForJSON(content);
console.log(JSON.stringify({ content: cleanContent }));
```
### Exit code issues
**Verify script returns correct codes:**
```bash
#!/usr/bin/env bash
set -e # Exit on error
# Processing logic
if validate_input; then
echo "Success"
exit 0
else
echo "Validation failed" >&2
exit 2
fi
```
**Check for unintended errors:**
```bash
#!/usr/bin/env bash
# Don't use 'set -e' if you want to handle errors explicitly
# set -e
if ! command_that_might_fail; then
# Handle error
echo "Command failed but continuing" >&2
fi
# Always exit explicitly
exit 0
```
**Use trap for cleanup:**
```bash
#!/usr/bin/env bash
cleanup() {
# Cleanup logic
rm -f /tmp/hook-temp-*
}
trap cleanup EXIT
# Hook logic here
```
### Environment variables not available
**Check if variable is set:**
```bash
#!/usr/bin/env bash
if [ -z "$GEMINI_PROJECT_DIR" ]; then
echo "GEMINI_PROJECT_DIR not set" >&2
exit 1
fi
if [ -z "$CUSTOM_VAR" ]; then
echo "Warning: CUSTOM_VAR not set, using default" >&2
CUSTOM_VAR="default-value"
fi
```
**Debug available variables:**
```bash
#!/usr/bin/env bash
# List all environment variables
env > .gemini/hook-env.log
# Check specific variables
echo "GEMINI_PROJECT_DIR: $GEMINI_PROJECT_DIR" >> .gemini/hook-env.log
echo "GEMINI_SESSION_ID: $GEMINI_SESSION_ID" >> .gemini/hook-env.log
echo "GEMINI_API_KEY: ${GEMINI_API_KEY:+<set>}" >> .gemini/hook-env.log
```
**Use .env files:**
```bash
#!/usr/bin/env bash
# Load .env file if it exists
if [ -f "$GEMINI_PROJECT_DIR/.env" ]; then
source "$GEMINI_PROJECT_DIR/.env"

default in the system configuration (e.g., `/etc/gemini-cli/settings.json`):
```json
{
"security": {
"environmentVariableRedaction": {
"enabled": true,
"allowed": ["MY_REQUIRED_TOOL_KEY"]
"blocked": ["MY_SECRET_KEY"],
"allowed": ["SAFE_VAR"]
}
}
}
```
**System administrators:** You can enforce redaction for all users in the system
configuration.
## Troubleshooting
### Hook not executing
**Check hook name in `/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:** Verify the hook is not listed in your `settings.json`:
```json
{
"hooks": {
"disabled": ["my-hook-name"]
}
}
```
**Ensure script is executable**: For macOS and Linux users, verify the script
has execution permissions:
```bash
ls -la .gemini/hooks/my-hook.sh
chmod +x .gemini/hooks/my-hook.sh
```
**Verify script path:** Ensure the path in `settings.json` resolves correctly.
```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:** The default is 60000ms (1 minute). You can
increase this in `settings.json`:
```json
{
"name": "slow-hook",
"timeout": 120000
}
```
**Optimize slow operations:** Move heavy processing to background tasks or use
caching.
### 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
```
### Environment variables not available
**Check if variable is set:**
```bash
#!/usr/bin/env bash
if [ -z "$GEMINI_PROJECT_DIR" ]; then
echo "GEMINI_PROJECT_DIR not set" >&2
exit 1
fi
```
**Debug available variables:**
```bash
env > .gemini/hook-env.log
```

Hook inputs and outputs may contain sensitive information. Gemini CLI respects
the `telemetry.logPrompts` setting for hook data logging.
### What data is collected
Hook telemetry may include inputs (prompts, code) and outputs (decisions,
reasons) unless disabled.
Hook telemetry may include:
- **Hook inputs:** User prompts, tool arguments, file contents
- **Hook outputs:** Hook responses, decision reasons, added context
- **Standard streams:** stdout and stderr from hook processes
- **Execution metadata:** Hook name, event type, duration, success/failure
### Privacy settings

logging in your settings:
**Enabled (default):**
Full hook I/O is logged to telemetry. Use this when:
- Developing and debugging hooks
- Telemetry is redirected to a trusted enterprise system
- You understand and accept the privacy implications
**Disabled:**
Only metadata is logged (event name, duration, success/failure). Hook inputs and
outputs are excluded. Use this when:

## 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.
With hooks, you can:
## Security and Risks
- **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.

### Getting started
- **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.

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.

## Core concepts
### Hook events
Hooks are triggered by specific events in Gemini CLI's lifecycle.
Hooks are triggered by specific events in Gemini CLI's lifecycle. The following
table lists all available hook events:
| Event | When It Fires | Impact | Common Use Cases |
| --------------------- | ---------------------------------------------- | ---------------------- | -------------------------------------------- |
| `SessionStart` | When a session begins (startup, resume, clear) | Inject Context | Initialize resources, load context |
| `SessionEnd` | When a session ends (exit, clear) | Advisory | Clean up, save state |
| `BeforeAgent` | After user submits prompt, before planning | Block Turn / Context | Add context, validate prompts, block turns |
| `AfterAgent` | When agent loop ends | Retry / Halt | Review output, force retry or halt execution |
| `BeforeModel` | Before sending request to LLM | Block Turn / Mock | Modify prompts, swap models, mock responses |
| `AfterModel` | After receiving LLM response | Block Turn / Redact | Filter/redact responses, log interactions |
| `BeforeToolSelection` | Before LLM selects tools | Filter Tools | Filter available tools, optimize selection |
| `BeforeTool` | Before a tool executes | Block Tool / Rewrite | Validate arguments, block dangerous ops |
| `AfterTool` | After a tool executes | Block Result / Context | Process results, run tests, hide results |
| `PreCompress` | Before context compression | Advisory | Save state, notify user |
| `Notification` | When a system notification occurs | Advisory | Forward to desktop alerts, logging |

### Global mechanics
### Hook types
Understanding these core principles is essential for building robust hooks.
Gemini CLI currently supports **command hooks** that run shell commands or
scripts:
#### Strict JSON requirements (The "Golden Rule")
```json
{
"type": "command",
"command": "$GEMINI_PROJECT_DIR/.gemini/hooks/my-hook.sh",
"timeout": 30000
}
```
Hooks communicate via `stdin` (Input) and `stdout` (Output).
**Note:** Plugin hooks (npm packages) are planned for a future release.
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.
### Matchers
#### 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.

**Matcher patterns:**

- **Wildcard:** `"*"` or `""` matches all tools
**Session event matchers:**
- **SessionStart:** `startup`, `resume`, `clear`
- **SessionEnd:** `exit`, `clear`, `logout`, `prompt_input_exit`
- **PreCompress:** `manual`, `auto`

## Hook input/output contract
### Command hook communication
Hooks communicate via:
- **Input:** JSON on stdin
- **Output:** Exit code + stdout/stderr
### Exit codes
- **0:** Success - stdout shown to user (or injected as context for some events)
- **2:** Blocking error - stderr shown to agent/user, operation may be blocked
- **Other:** Non-blocking warning - logged but execution continues
### Common input fields
Every hook receives these base fields:
```json
{
"session_id": "abc123",
"transcript_path": "/path/to/transcript.jsonl",
"cwd": "/path/to/project",
"hook_event_name": "BeforeTool",

## 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.
### Configuration schema

| `description` | string | No | A brief explanation of the hook's purpose. |
---
- **`name`** (string, recommended): Unique identifier for the hook used in
`/hooks enable/disable` commands. If omitted, the `command` path is used as
the identifier.
- **`type`** (string, required): Hook type - currently only `"command"` is
supported
- **`command`** (string, required): Path to the script or command to execute
- **`description`** (string, optional): Human-readable description shown in
`/hooks panel`
- **`timeout`** (number, optional): Timeout in milliseconds (default: 60000)
- **`matcher`** (string, optional): Pattern to filter when hook runs (event
matchers only)
### Environment variables
Hooks are executed with a sanitized environment.
Hooks have access to:
- `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.
- `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
## Managing hooks
Use the CLI commands to manage hooks without editing JSON manually:
### View registered hooks
- **View hooks:** `/hooks panel`
- **Enable/Disable all:** `/hooks enable-all` or `/hooks disable-all`
- **Toggle individual:** `/hooks enable <name>` or `/hooks disable <name>`
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 JSON schemas and API details.
including the JSON schemas for input and output, exit code behaviors, and the
stable model API.
## Global hook mechanics
## Communication Protocol
- **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.
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. |
---
## Configuration schema
## Input Schema (`stdin`)
Hooks are defined in `settings.json` within the `hooks` object. Each event
(e.g., `BeforeTool`) contains an array of **hook definitions**.
Every hook receives a base JSON object. Extra fields are added depending on the
specific event.
### Hook definition
### Base Fields (All Events)
| Field | Type | Required | Description |
| :----------- | :-------- | :------- | :-------------------------------------------------------------------------------------- |
| `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**. |
| Field | Type | Description |
| :---------------- | :------- | :---------------------------------------------------- |
| `session_id` | `string` | Unique identifier for the current CLI session. |

## Base input schema
## Output Schema (`stdout`)
All hooks receive these common fields via `stdin`:
If the hook exits with `0`, the CLI attempts to parse `stdout` as JSON.
```typescript
{
"session_id": string, // Unique ID for the current session
"transcript_path": string, // Absolute path to session transcript JSON
"cwd": string, // Current working directory
"hook_event_name": string, // The firing event (e.g. "BeforeTool")
"timestamp": string // ISO 8601 execution time
}
```
### Common Output Fields
---
| Field | Type | Description |
| :------------------- | :-------- | :------------------------------------------------------------------------------------- |
| `decision` | `string` | One of: `allow`, `deny`, `block`, `ask`, `approve`. |
| `reason` | `string` | Explanation shown to the **agent** when a decision is `deny` or `block`. |
| `systemMessage` | `string` | Message displayed in Gemini CLI terminal to provide warning or context to the **user** |
| `continue` | `boolean` | If `false`, immediately terminates the agent loop for this turn. |
| `stopReason` | `string` | Message shown to the user when `continue` is `false`. |
| `suppressOutput` | `boolean` | If `true`, the hook execution is hidden from the CLI transcript. |
| `hookSpecificOutput` | `object` | Container for event-specific data (see below). |
## Common output fields
### `hookSpecificOutput` Reference
Most hooks support these fields in their `stdout` JSON:
| Field | Type | Description |
| :--------------- | :-------- | :----------------------------------------------------------------------------- |
| `systemMessage` | `string` | Displayed immediately to the user in the terminal. |
| `suppressOutput` | `boolean` | If `true`, hides internal hook metadata from logs/telemetry. |
| `continue` | `boolean` | If `false`, stops the entire agent loop immediately. |
| `stopReason` | `string` | Displayed to the user when `continue` is `false`. |
| `decision` | `string` | `"allow"` or `"deny"` (alias `"block"`). Specific impact depends on the event. |
| `reason` | `string` | The feedback/error message provided when a `decision` is `"deny"`. |
---
## 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.
- `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.
| Field | Supported Events | Description |
| :------------------ | :----------------------------------------- | :-------------------------------------------------------------------------------- |
| `additionalContext` | `SessionStart`, `BeforeAgent`, `AfterTool` | Appends text directly to the agent's context. |
| `llm_request` | `BeforeModel` | A `Partial<LLMRequest>` to override parameters of the outgoing call. |
| `llm_response` | `BeforeModel` | A **full** `LLMResponse` to bypass the model and provide a synthetic result. |
| `llm_response` | `AfterModel` | A `Partial<LLMResponse>` to modify the model's response before the agent sees it. |
| `toolConfig` | `BeforeToolSelection` | Object containing `mode` (`AUTO`/`ANY`/`NONE`) and `allowedFunctionNames`. |
---
## Stable Model API
Gemini CLI uses these structures to ensure hooks don't break across SDK updates.
Gemini CLI uses a decoupled format for model interactions to ensure hooks remain
stable even if the underlying Gemini SDK changes.
**LLMRequest**:
### `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.
```typescript
{
"model": string,
"messages": Array<{
"role": "user" | "model" | "system",
"content": string // Non-text parts are filtered out for hooks
"content": string | Array<{ "type": string, [key: string]: any }>
}>,
"config": { "temperature": number, ... },
"toolConfig": { "mode": string, "allowedFunctionNames": string[] }
"config"?: {
"temperature"?: number,
"maxOutputTokens"?: number,
"topP"?: number,
"topK"?: number
},
"toolConfig"?: {
"mode"?: "AUTO" | "ANY" | "NONE",
"allowedFunctionNames"?: string[]
}
}
```
**LLMResponse**:
### `LLMResponse` Object
Used in `AfterModel` and as a synthetic response in `BeforeModel`.
```typescript
{
"text"?: string,
"candidates": Array<{
"content": { "role": "model", "parts": string[] },
"finishReason": string
"content": {
"role": "model",
"parts": string[]
},
"finishReason"?: "STOP" | "MAX_TOKENS" | "SAFETY" | "RECITATION" | "OTHER",
"index"?: number,
"safetyRatings"?: Array<{
"category": string,
"probability": string,
"blocked"?: boolean
}>
}>,
"usageMetadata": { "totalTokenCount": number }
"usageMetadata"?: {
"promptTokenCount"?: number,
"candidatesTokenCount"?: number,
"totalTokenCount"?: number
}
}
```

@@ -144,48 +144,6 @@ 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.
## 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.
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.

## React & Ink (CLI UI)
- **Side Effects**: Use reducers for complex state transitions; avoid `setState`
triggers in callbacks.
- Always fix react-hooks/exhaustive-deps lint errors by adding the missing
dependencies.
- **Shortcuts**: only define keyboard shortcuts in
`packages/cli/src/config/keyBindings.ts
## Testing
- **Utilities**: Use `renderWithProviders` and `waitFor` from
`packages/cli/src/test-utils/`.
- **Snapshots**: Use `toMatchSnapshot()` to verify Ink output.
- **Mocks**: Use mocks as sparingly as possilble.

# Ink Library Screen Reader Guidance
When building custom components, it's important to keep accessibility in mind.
While Ink provides the building blocks, ensuring your components are accessible
will make your CLIs usable by a wider audience.
## General Principles
Provide screen reader-friendly output: Use the useIsScreenReaderEnabled hook to
detect if a screen reader is active. You can then render a more descriptive
output for screen reader users. Leverage ARIA props: For components that have a
specific role (e.g., a checkbox or a button), use the aria-role, aria-state, and
aria-label props on <Box> and <Text> to provide semantic meaning to screen
readers.

# MCP Server Example
This is a basic example of an MCP (Model Context Protocol) server used as a
Gemini CLI extension. It demonstrates how to expose tools and prompts to the
Gemini CLI.
## Description
The contents of this directory are a valid MCP server implementation using the
`@modelcontextprotocol/sdk`. It exposes:
- A tool `fetch_posts` that mock-fetches posts.
- A prompt `poem-writer`.
## Structure
- `example.js`: The main server entry point.
- `gemini-extension.json`: The configuration file that tells Gemini CLI how to
use this extension.
- `package.json`: Helper for dependencies.
## How to Use
1. Navigate to this directory:
```bash
cd packages/cli/src/commands/extensions/examples/mcp-server
```
2. Install dependencies:
```bash
npm install
```
This example is typically used by `gemini extensions new`.
