-# 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 when asked to write documentation (`/docs` directory)
-  for Gemini CLI.
----
-
-# `docs-writer` skill instructions
-
-As an expert technical writer for the Gemini CLI project, your goal is to
-produce documentation that is accurate, clear, and consistent with the project's
-standards. You must adhere to the documentation contribution process outlined in
-`CONTRIBUTING.md` and the style guidelines from the Google Developer
-Documentation Style Guide.
-
-## 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 to be documented.
-2.  **Ask questions:** If the request is ambiguous or lacks detail, ask
-    clarifying questions. Don't invent or assume. It's better to ask than to
-    write incorrect documentation.
-3.  **Formulate a plan:** Create a clear, step-by-step plan for the required
-    changes. If requested or necessary, store this plan in a temporary file or
-    a file identified by the user.
-
-## Step 2: Investigate and gather information
-
-1.  **Read the code:** Thoroughly examine the relevant codebase, primarily within
-    the `packages/` directory, to ensure your writing is backed by the
-    implementation.
-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 to edit it.
-3.  **Check for connections:** Consider related documentation. If you add a new
-    page, check if `docs/sidebar.json` needs to be updated. If you change a
-    command's behavior, check for other pages that reference it. Make sure links
-    in these pages are up to date.
-
-## Step 3: Draft the documentation
-
-1.  **Follow the style guide:**
-    - Text must be wrapped at 80 characters. Exceptions are long links or
-      tables, unless otherwise stated by the user.
-    - Use sentence case for headings, titles, and bolded text.
-    - Address the reader as "you".
-    - Use contractions to keep the tone more casual.
-    - Use simple, direct, and active language and the present tense.
-    - Keep paragraphs short and focused.
-    - Always refer to Gemini CLI as `Gemini CLI`, never `the Gemini CLI`.
-2.  **Use `replace` and `write_file`:** Use the file system tools to apply your
-    planned changes precisely. For small edits, `replace` is preferred. For new
-    files or large rewrites, `write_file` is more appropriate.
-
-## Step 4: Verify and finalize
-
-1.  **Review your work:** After making changes, re-read the files to ensure the
-    documentation is well-formatted, content is correct and based on existing
-    code, and that all new links are valid.
-2.  **Offer to run npm format:** Once all changes are complete and the user
-    confirms they have no more requests, offer to run the project's formatting
-    script to ensure consistency. Propose the following command:
-    `npm run format`

-# 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.
+
+## Git Repo
+
+The main branch for this project is called "main"
+
+## JavaScript/TypeScript
+
+When contributing to this React, Node, and TypeScript codebase, please
+prioritize the use of plain JavaScript objects with accompanying TypeScript
+interface or type declarations over JavaScript class syntax. This approach
+offers significant advantages, especially concerning interoperability with React
+and overall code maintainability.
+
+### Preferring Plain Objects over Classes
+
+JavaScript classes, by their nature, are designed to encapsulate internal state
+and behavior. While this can be useful in some object-oriented paradigms, it
+often introduces unnecessary complexity and friction when working with React's
+component-based architecture. Here's why plain objects are preferred:
+
+- Seamless React Integration: React components thrive on explicit props and
+  state management. Classes' tendency to store internal state directly within
+  instances can make prop and state propagation harder to reason about and
+  maintain. Plain objects, on the other hand, are inherently immutable (when
+  used thoughtfully) and can be easily passed as props, simplifying data flow
+  and reducing unexpected side effects.
+
+- Reduced Boilerplate and Increased Conciseness: Classes often promote the use
+  of constructors, this binding, getters, setters, and other boilerplate that
+  can unnecessarily bloat code. TypeScript interface and type declarations
+  provide powerful static type checking without the runtime overhead or
+  verbosity of class definitions. This allows for more succinct and readable
+  code, aligning with JavaScript's strengths in functional programming.
+
+- Enhanced Readability and Predictability: Plain objects, especially when their
+  structure is clearly defined by TypeScript interfaces, are often easier to
+  read and understand. Their properties are directly accessible, and there's no
+  hidden internal state or complex inheritance chains to navigate. This
+  predictability leads to fewer bugs and a more maintainable codebase.
+
+- Simplified Immutability: While not strictly enforced, plain objects encourage
+  an immutable approach to data. When you need to modify an object, you
+  typically create a new one with the desired changes, rather than mutating the
+  original. This pattern aligns perfectly with React's reconciliation process
+  and helps prevent subtle bugs related to shared mutable state.
+
+- Better Serialization and Deserialization: Plain JavaScript objects are
+  naturally easy to serialize to JSON and deserialize back, which is a common
+  requirement in web development (e.g., for API communication or local storage).
+  Classes, with their methods and prototypes, can complicate this process.
+
+### Embracing ES Module Syntax for Encapsulation
+
+Rather than relying on Java-esque private or public class members, which can be
+verbose and sometimes limit flexibility, we strongly prefer leveraging ES module
+syntax (`import`/`export`) for encapsulating private and public APIs.
+
+- Clearer Public API Definition: With ES modules, anything that is exported is
+  part of the public API of that module, while anything not exported is
+  inherently private to that module. This provides a very clear and explicit way
+  to define what parts of your code are meant to be consumed by other modules.
+
+- Enhanced Testability (Without Exposing Internals): By default, unexported
+  functions or variables are not accessible from outside the module. This
+  encourages you to test the public API of your modules, rather than their
+  internal implementation details. If you find yourself needing to spy on or
+  stub an unexported function for testing purposes, it's often a "code smell"
+  indicating that the function might be a good candidate for extraction into its
+  own separate, testable module with a well-defined public API. This promotes a
+  more robust and maintainable testing strategy.
+
+- Reduced Coupling: Explicitly defined module boundaries through import/export
+  help reduce coupling between different parts of your codebase. This makes it
+  easier to refactor, debug, and understand individual components in isolation.
+
+### Avoiding `any` Types and Type Assertions; Preferring `unknown`
+
+TypeScript's power lies in its ability to provide static type checking, catching
+potential errors before your code runs. To fully leverage this, it's crucial to
+avoid the `any` type and be judicious with type assertions.
+
+- **The Dangers of `any`**: Using any effectively opts out of TypeScript's type
+  checking for that particular variable or expression. While it might seem
+  convenient in the short term, it introduces significant risks:
+  - **Loss of Type Safety**: You lose all the benefits of type checking, making
+    it easy to introduce runtime errors that TypeScript would otherwise have
+    caught.
+  - **Reduced Readability and Maintainability**: Code with `any` types is harder
+    to understand and maintain, as the expected type of data is no longer
+    explicitly defined.
+  - **Masking Underlying Issues**: Often, the need for any indicates a deeper
+    problem in the design of your code or the way you're interacting with
+    external libraries. It's a sign that you might need to refine your types or
+    refactor your code.
+
+- **Preferring `unknown` over `any`**: When you absolutely cannot determine the
+  type of a value at compile time, and you're tempted to reach for any, consider
+  using unknown instead. unknown is a type-safe counterpart to any. While a
+  variable of type unknown can hold any value, you must perform type narrowing
+  (e.g., using typeof or instanceof checks, or a type assertion) before you can
+  perform any operations on it. This forces you to handle the unknown type
+  explicitly, preventing accidental runtime errors.
+
+  ```ts
+  function processValue(value: unknown) {
+    if (typeof value === 'string') {
+      // value is now safely a string
+      console.log(value.toUpperCase());
+    } else if (typeof value === 'number') {
+      // value is now safely a number
+      console.log(value * 2);
+    }
+    // Without narrowing, you cannot access properties or methods on 'value'
+    // console.log(value.someProperty); // Error: Object is of type 'unknown'.
+  }
+  ```
+
+- **Type Assertions (`as Type`) - Use with Caution**: Type assertions tell the
+  TypeScript compiler, "Trust me, I know what I'm doing; this is definitely of
+  this type." While there are legitimate use cases (e.g., when dealing with
+  external libraries that don't have perfect type definitions, or when you have
+  more information than the compiler), they should be used sparingly and with
+  extreme caution.
+  - **Bypassing Type Checking**: Like `any`, type assertions bypass TypeScript's
+    safety checks. If your assertion is incorrect, you introduce a runtime error
+    that TypeScript would not have warned you about.
+  - **Code Smell in Testing**: A common scenario where `any` or type assertions
+    might be tempting is when trying to test "private" implementation details
+    (e.g., spying on or stubbing an unexported function within a module). This
+    is a strong indication of a "code smell" in your testing strategy and
+    potentially your code structure. Instead of trying to force access to
+    private internals, consider whether those internal details should be
+    refactored into a separate module with a well-defined public API. This makes
+    them inherently testable without compromising encapsulation.
+
+### Type narrowing `switch` clauses
+
+Use the `checkExhaustive` helper in the default clause of a switch statement.
+This will ensure that all of the possible options within the value or
+enumeration are used.
+
+This helper method can be found in `packages/cli/src/utils/checks.ts`
+
+### Embracing JavaScript's Array Operators
+
+To further enhance code cleanliness and promote safe functional programming
+practices, leverage JavaScript's rich set of array operators as much as
+possible. Methods like `.map()`, `.filter()`, `.reduce()`, `.slice()`,
+`.sort()`, and others are incredibly powerful for transforming and manipulating
+data collections in an immutable and declarative way.
+
+Using these operators:
+
+- Promotes Immutability: Most array operators return new arrays, leaving the
+  original array untouched. This functional approach helps prevent unintended
+  side effects and makes your code more predictable.
+- Improves Readability: Chaining array operators often lead to more concise and
+  expressive code than traditional for loops or imperative logic. The intent of
+  the operation is clear at a glance.
+- Facilitates Functional Programming: These operators are cornerstones of
+  functional programming, encouraging the creation of pure functions that take
+  inputs and produce outputs without causing side effects. This paradigm is
+  highly beneficial for writing robust and testable code that pairs well with
+  React.
+
+By consistently applying these principles, we can maintain a codebase that is
+not only efficient and performant but also a joy to work with, both now and in
+the future.

+
+### Role
+
+You are a React assistant that helps users write more efficient and optimizable
+React code. You specialize in identifying patterns that enable React Compiler to
+automatically apply optimizations, reducing unnecessary re-renders and improving
+application performance.
+
+### Follow these guidelines in all code you produce and suggest
+
+Use functional components with Hooks: Do not generate class components or use
+old lifecycle methods. Manage state with useState or useReducer, and side
+effects with useEffect (or related Hooks). Always prefer functions and Hooks for
+any new component logic.
+
+Keep components pure and side-effect-free during rendering: Do not produce code
+that performs side effects (like subscriptions, network requests, or modifying
+external variables) directly inside the component's function body. Such actions
+should be wrapped in useEffect or performed in event handlers. Ensure your
+render logic is a pure function of props and state.
+
+Respect one-way data flow: Pass data down through props and avoid any global
+mutations. If two components need to share data, lift that state up to a common
+parent or use React Context, rather than trying to sync local state or use
+external variables.
+
+Never mutate state directly: Always generate code that updates state immutably.
+For example, use spread syntax or other methods to create new objects/arrays
+when updating state. Do not use assignments like state.someValue = ... or array
+mutations like array.push() on state variables. Use the state setter (setState
+from useState, etc.) to update state.
+
+Accurately use useEffect and other effect Hooks: whenever you think you could
+useEffect, think and reason harder to avoid it. useEffect is primarily only used
+for synchronization, for example synchronizing React with some external state.
+IMPORTANT - Don't setState (the 2nd value returned by useState) within a
+useEffect as that will degrade performance. When writing effects, include all
+necessary dependencies in the dependency array. Do not suppress ESLint rules or
+omit dependencies that the effect's code uses. Structure the effect callbacks to
+handle changing values properly (e.g., update subscriptions on prop changes,
+clean up on unmount or dependency change). If a piece of logic should only run
+in response to a user action (like a form submission or button click), put that
+logic in an event handler, not in a useEffect. Where possible, useEffects should
+return a cleanup function.
+
+Follow the Rules of Hooks: Ensure that any Hooks (useState, useEffect,
+useContext, custom Hooks, etc.) are called unconditionally at the top level of
+React function components or other Hooks. Do not generate code that calls Hooks
+inside loops, conditional statements, or nested helper functions. Do not call
+Hooks in non-component functions or outside the React component rendering
+context.
+
+Use refs only when necessary: Avoid using useRef unless the task genuinely
+requires it (such as focusing a control, managing an animation, or integrating
+with a non-React library). Do not use refs to store application state that
+should be reactive. If you do use refs, never write to or read from ref.current
+during the rendering of a component (except for initial setup like lazy
+initialization). Any ref usage should not affect the rendered output directly.
+
+Prefer composition and small components: Break down UI into small, reusable
+components rather than writing large monolithic components. The code you
+generate should promote clarity and reusability by composing components
+together. Similarly, abstract repetitive logic into custom Hooks when
+appropriate to avoid duplicating code.
+
+Optimize for concurrency: Assume React may render your components multiple times
+for scheduling purposes (especially in development with Strict Mode). Write code
+that remains correct even if the component function runs more than once. For
+instance, avoid side effects in the component body and use functional state
+updates (e.g., setCount(c => c + 1)) when updating state based on previous state
+to prevent race conditions. Always include cleanup functions in effects that
+subscribe to external resources. Don't write useEffects for "do this when this
+changes" side effects. This ensures your generated code will work with React's
+concurrent rendering features without issues.
+
+Optimize to reduce network waterfalls - Use parallel data fetching wherever
+possible (e.g., start multiple requests at once rather than one after another).
+Leverage Suspense for data loading and keep requests co-located with the
+component that needs the data. In a server-centric approach, fetch related data
+together in a single request on the server side (using Server Components, for
+example) to reduce round trips. Also, consider using caching layers or global
+fetch management to avoid repeating identical requests.
+
+Rely on React Compiler - useMemo, useCallback, and React.memo can be omitted if
+React Compiler is enabled. Avoid premature optimization with manual memoization.
+Instead, focus on writing clear, simple components with direct data flow and
+side-effect-free render functions. Let the React Compiler handle tree-shaking,
+inlining, and other performance enhancements to keep your code base simpler and
+more maintainable.
+
+Design for a good user experience - Provide clear, minimal, and non-blocking UI
+states. When data is loading, show lightweight placeholders (e.g., skeleton
+screens) rather than intrusive spinners everywhere. Handle errors gracefully
+with a dedicated error boundary or a friendly inline message. Where possible,
+render partial data as it becomes available rather than making the user wait for
+everything. Suspense allows you to declare the loading states in your component
+tree in a natural way, preventing “flash” states and improving perceived
+performance.
+
+### Process
+
+1. Analyze the user's code for optimization opportunities:
+   - Check for React anti-patterns that prevent compiler optimization
+   - Look for component structure issues that limit compiler effectiveness
+   - Think about each suggestion you are making and consult React docs for best
+     practices
+
+2. Provide actionable guidance:
+   - Explain specific code changes with clear reasoning
+   - Show before/after examples when suggesting changes
+   - Only suggest changes that meaningfully improve optimization potential
+
+### Optimization Guidelines
+
+- State updates should be structured to enable granular updates
+- Side effects should be isolated and dependencies clearly defined
+
+## 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`.

-
-- **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.

-| **[Custom commands](../cli/custom-commands.md)**               | A shortcut (like `/my-cmd`) that executes a pre-defined prompt or shell command.                                   | Use this for repetitive tasks or to save long, complex prompts that you use frequently.

 [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`.

+### 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"`.

-# 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.
-
-### Conflict resolution
-
-Extension commands have the lowest precedence. When a conflict occurs with user
-or project commands:
-
-1. **No conflict**: Extension command uses its natural name (e.g., `/deploy`)
-2. **With conflict**: Extension command is renamed with the extension prefix
-   (e.g., `/gcp.deploy`)
-
-For example, if both a user and the `gcp` extension define a `deploy` command:
-
-- `/deploy` - Executes the user's deploy command
-- `/gcp.deploy` - Executes the extension's deploy command (marked with `[gcp]`
-  tag)
-
-## Variables
-
-Gemini CLI extensions allow variable substitution in `gemini-extension.json`.
-This can be useful if e.g., you need the current directory to run an MCP server
-using an argument like `"args": ["${extensionPath}${/}dist${/}server.js"]`.
-
-**Supported variables:**
-
-| variable                   | description                                                                                                                                                     |

 ### 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');

 ### 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.

->
-> **Blocking vs. Stopping**: Use `decision: "deny"` (or Exit Code 2) to block a
-> **specific action**. Use `{"continue": false}` in your JSON output to **kill
-> the entire agent loop** immediately.

+
+## 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

 ## 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.
+> **Warning: Hooks execute arbitrary code with your user privileges.**
+>
+> By configuring hooks, you are explicitly allowing Gemini CLI to run shell
+> commands on your machine. Malicious or poorly configured hooks can:
+
+- **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.
+
+**Project-level hooks** (in `.gemini/settings.json`) and **Extension hooks** are
+particularly risky when opening third-party projects or extensions from
+untrusted authors. Gemini CLI will **warn you** the first time it detects a new
+project hook (identified by its name and command), but it is **your
+responsibility** to review these hooks (and any installed extensions) before
+trusting them.
+
+> **Note:** Extension hooks are subject to a mandatory security warning and
+> consent flow during extension installation or update if hooks are detected.
+> You must explicitly approve the installation or update of any extension that
+> contains hooks.
+
+See [Security Considerations](best-practices.md#using-hooks-securely) for a
+detailed threat model and mitigation strategies.

-### 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.

+
+## 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
+
+```json

+- **`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 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

-## 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.

+| :------------------ | :----------------------------------------- | :-------------------------------------------------------------------------------- |
+| `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[] }

+    "allowedFunctionNames"?: string[]
+  }
 }
-
 ```
 
-**LLMResponse**:

+    "safetyRatings"?: Array<{
+      "category": string,
+      "probability": string,

-# 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`.
