+# How to Contribute
+
+We would love to accept your patches and contributions to this project.
+
+## Before you begin
+
+### Sign our Contributor License Agreement
+
+Contributions to this project must be accompanied by a
+[Contributor License Agreement](https://cla.developers.google.com/about) (CLA).
+You (or your employer) retain the copyright to your contribution; this simply
+gives us permission to use and redistribute your contributions as part of the
+project.
+
+If you or your current employer have already signed the Google CLA (even if it
+was for a different project), you probably don't need to do it again.
+
+Visit <https://cla.developers.google.com/> to see your current agreements or to
+sign a new one.
+
+### Review our Community Guidelines
+
+This project follows [Google's Open Source Community
+Guidelines](https://opensource.google/conduct/).
+
+## Contribution Process
+
+### Code Reviews
+
+All submissions, including submissions by project members, require review. We
+use [GitHub pull requests](https://docs.github.com/articles/about-pull-requests)
+for this purpose.
+
+### Pull Request Guidelines
+
+To help us review and merge your PRs quickly, please follow these guidelines. PRs that do not meet these standards may be closed.
+
+#### 1. Link to an Existing Issue
+
+All PRs should be linked to an existing issue in our tracker. This ensures that every change has been discussed and is aligned with the project's goals before any code is written.
+
+- **For bug fixes:** The PR should be linked to the bug report issue.
+- **For features:** The PR should be linked to the feature request or proposal issue that has been approved by a maintainer.
+
+If an issue for your change doesn't exist, please **open one first** and wait for feedback before you start coding.
+
+#### 2. Keep It Small and Focused
+
+We favor small, atomic PRs that address a single issue or add a single, self-contained feature.
+
+- **Do:** Create a PR that fixes one specific bug or adds one specific feature.
+- **Don't:** Bundle multiple unrelated changes (e.g., a bug fix, a new feature, and a refactor) into a single PR.
+
+Large changes should be broken down into a series of smaller, logical PRs that can be reviewed and merged independently.
+
+#### 3. Use Draft PRs for Work in Progress
+
+If you'd like to get early feedback on your work, please use GitHub's **Draft Pull Request** feature. This signals to the maintainers that the PR is not yet ready for a formal review but is open for discussion and initial feedback.
+
+#### 4. Ensure All Checks Pass
+
+Before submitting your PR, ensure that all automated checks are passing by running `npm run preflight`. This command runs all tests, linting, and other style checks.
+
+#### 5. Update Documentation
+
+If your PR introduces a user-facing change (e.g., a new command, a modified flag, or a change in behavior), you must also update the relevant documentation in the `/docs` directory.
+
+#### 6. Write Clear Commit Messages and a Good PR Description
+
+Your PR should have a clear, descriptive title and a detailed description of the changes. Follow the [Conventional Commits](https://www.conventionalcommits.org/) standard for your commit messages.
+
+- **Good PR Title:** `feat(cli): Add --json flag to 'config get' command`
+- **Bad PR Title:** `Made some changes`
+
+In the PR description, explain the "why" behind your changes and link to the relevant issue (e.g., `Fixes #123`).
+
+## Forking
+
+If you are forking the repository you will be able to run the Built, Test and Integration test workflows. However in order to make the integration tests run you'll need to add a [GitHub Repository Secret](<[url](https://docs.github.com/en/actions/security-for-github-actions/security-guides/using-secrets-in-github-actions#creating-secrets-for-a-repository)>) with a value of `GEMINI_API_KEY` and set that to a valid API key that you have available. Your key and secret are private to your repo; no one without access can see your key and you cannot see any secrets related to this repo.
+
+Additionally you will need to click on the `Actions` tab and enable workflows for your repository, you'll find it's the large blue button in the center of the screen.
+
+## Development Setup and Workflow
+
+This section guides contributors on how to build, modify, and understand the development setup of this project.
+
+### Setting Up the Development Environment
+
+**Prerequisites:**
+
+1. Install [Node 18+](https://nodejs.org/en/download)
+2. Git
+
+### Build Process
+
+To clone the repository:
+
+```bash
+git clone https://github.com/google-gemini/gemini-cli.git # Or your fork's URL
+cd gemini-cli
+```
+
+To install dependencies defined in `package.json` as well as root dependencies:
+
+```bash
+npm install
+```
+
+To build the entire project (all packages):
+
+```bash
+npm run build
+```
+
+This command typically compiles TypeScript to JavaScript, bundles assets, and prepares the packages for execution. Refer to `scripts/build.js` and `package.json` scripts for more details on what happens during the build.
+
+### Enabling Sandboxing
+
+Container-based [sandboxing](#sandboxing) is highly recommended and requires, at a minimum, setting `GEMINI_SANDBOX=true` in your `~/.env` and ensuring a container engine (e.g. `docker` or `podman`) is available. See [Sandboxing](#sandboxing) for details.
+
+To build both the `gemini` CLI utility and the sandbox container, run `build:all` from the root directory:
+
+```bash
+npm run build:all
+```
+
+To skip building the sandbox container, you can use `npm run build` instead.
+
+### Running
+
+To start the Gemini CLI from the source code (after building), run the following command from the root directory:
+
+```bash
+npm start
+```
+
+If you’d like to run the source build outside of the gemini-cli folder you can utilize `npm link path/to/gemini-cli/packages/cli` (see: [docs](https://docs.npmjs.com/cli/v9/commands/npm-link)) or `alias gemini="node path/to/gemini-cli/packages/cli"` to run with `gemini`
+
+### Running Tests
+
+This project contains two types of tests: unit tests and integration tests.
+
+#### Unit Tests
+
+To execute the unit test suite for the project:
+
+```bash
+npm run test
+```
+
+This will run tests located in the `packages/core` and `packages/cli` directories. Ensure tests pass before submitting any changes. For a more comprehensive check, it is recommended to run `npm run preflight`.
+
+#### Integration Tests
+
+The integration tests are designed to validate the end-to-end functionality of the Gemini CLI. They are not run as part of the default `npm run test` command.
+
+To run the integration tests, use the following command:
+
+```bash
+npm run test:e2e
+```
+
+For more detailed information on the integration testing framework, please see the [Integration Tests documentation](./docs/integration-tests.md).
+
+### Linting and Preflight Checks
+
+To ensure code quality and formatting consistency, run the preflight check:
+
+```bash
+npm run preflight
+```
+
+This command will run ESLint, Prettier, all tests, and other checks as defined in the project's `package.json`.
+
+_ProTip_
+
+after cloning create a git precommit hook file to ensure your commits are always clean.
+
+```bash
+echo "
+# Run npm build and check for errors
+if ! npm run preflight; then
+  echo "npm build failed. Commit aborted."
+  exit 1
+fi
+" > .git/hooks/pre-commit && chmod +x .git/hooks/pre-commit
+```
+
+#### Formatting
+
+To separately format the code in this project by running the following command from the root directory:
+
+```bash
+npm run format
+```
+
+This command uses Prettier to format the code according to the project's style guidelines.
+
+#### Linting
+
+To separately lint the code in this project, run the following command from the root directory:
+
+```bash
+npm run lint
+```
+
+### Coding Conventions
+
+- Please adhere to the coding style, patterns, and conventions used throughout the existing codebase.
+- Consult [GEMINI.md](https://github.com/google-gemini/gemini-cli/blob/main/GEMINI.md) (typically found in the project root) for specific instructions related to AI-assisted development, including conventions for React, comments, and Git usage.
+- **Imports:** Pay special attention to import paths. The project uses `eslint-rules/no-relative-cross-package-imports.js` to enforce restrictions on relative imports between packages.
+
+### Project Structure
+
+- `packages/`: Contains the individual sub-packages of the project.
+  - `cli/`: The command-line interface.
+  - `server/`: The backend server that the CLI interacts with.
+- `docs/`: Contains all project documentation.
+- `scripts/`: Utility scripts for building, testing, and development tasks.
+
+For more detailed architecture, see `docs/architecture.md`.
+
+## Debugging
+
+### VS Code:
+
+0.  Run the CLI to interactively debug in VS Code with `F5`
+1.  Start the CLI in debug mode from the root directory:
+    ```bash
+    npm run debug
+    ```
+    This command runs `node --inspect-brk dist/gemini.js` within the `packages/cli` directory, pausing execution until a debugger attaches. You can then open `chrome://inspect` in your Chrome browser to connect to the debugger.
+2.  In VS Code, use the "Attach" launch configuration (found in `.vscode/launch.json`).
+
+Alternatively, you can use the "Launch Program" configuration in VS Code if you prefer to launch the currently open file directly, but 'F5' is generally recommended.
+
+To hit a breakpoint inside the sandbox container run:
+
+```bash
+DEBUG=1 gemini
+```
+
+### React DevTools
+
+To debug the CLI's React-based UI, you can use React DevTools. Ink, the library used for the CLI's interface, is compatible with React DevTools version 4.x.
+
+1.  **Start the Gemini CLI in development mode:**
+
+    ```bash
+    DEV=true npm start
+    ```
+
+2.  **Install and run React DevTools version 4.28.5 (or the latest compatible 4.x version):**
+
+    You can either install it globally:
+
+    ```bash
+    npm install -g react-devtools@4.28.5
+    react-devtools
+    ```
+
+    Or run it directly using npx:
+
+    ```bash
+    npx react-devtools@4.28.5
+    ```
+
+    Your running CLI application should then connect to React DevTools.

+
+## Sandboxing
+
+### MacOS Seatbelt
+
+On MacOS, `gemini` uses Seatbelt (`sandbox-exec`) under a `permissive-open` profile (see `packages/cli/src/utils/sandbox-macos-permissive-open.sb`) that restricts writes to the project folder but otherwise allows all other operations and outbound network traffic ("open") by default. You can switch to a `restrictive-closed` profile (see `.../sandbox-macos-strict.sb`) that declines all operations and outbound network traffic ("closed") by default by setting `SEATBELT_PROFILE=restrictive-closed` in your environment or `.env` file. Available built-in profiles are `{permissive,restrictive}-{open,closed,proxied}` (see below for proxied networking). You can also switch to a custom profile `SEATBELT_PROFILE=<profile>` if you also create a file `.gemini/sandbox-macos-<profile>.sb` under your project settings directory `.gemini`.
+
+### Container-based Sandboxing (All Platforms)
+
+For stronger container-based sandboxing on MacOS or other platforms, you can set `GEMINI_SANDBOX=true|docker|podman|<command>` in your environment or `.env` file. The specified command (or if `true` then either `docker` or `podman`) must be installed on the host machine. Once enabled, `npm run build:all` will build a minimal container ("sandbox") image and `npm start` will launch inside a fresh instance of that container. The first build can take 20-30s (mostly due to downloading of the base image) but after that both build and start overhead should be minimal. Default builds (`npm run build`) will not rebuild the sandbox.
+
+Container-based sandboxing mounts the project directory (and system temp directory) with read-write access and is started/stopped/removed automatically as you start/stop Gemini CLI. Files created within the sandbox should be automatically mapped to your user/group on host machine. You can easily specify additional mounts, ports, or environment variables by setting `SANDBOX_{MOUNTS,PORTS,ENV}` as needed. You can also fully customize the sandbox for your projects by creating the files `.gemini/sandbox.Dockerfile` and/or `.gemini/sandbox.bashrc` under your project settings directory (`.gemini`) and running `gemini` with `BUILD_SANDBOX=1` to trigger building of your custom sandbox.
+
+#### Proxied Networking
+
+All sandboxing methods, including MacOS Seatbelt using `*-proxied` profiles, support restricting outbound network traffic through a custom proxy server that can be specified as `GEMINI_SANDBOX_PROXY_COMMAND=<command>`, where `<command>` must start a proxy server that listens on `:::8877` for relevant requests. See `scripts/example-proxy.js` for a minimal proxy that only allows `HTTPS` connections to `example.com:443` (e.g. `curl https://example.com`) and declines all other requests. The proxy is started and stopped automatically alongside the sandbox.
+
+## Manual Publish
+
+We publish an artifact for each commit to our internal registry. But if you need to manually cut a local build, then run the following commands:
+
+```
+npm run clean
+npm install
+npm run auth
+npm run prerelease:dev
+npm publish --workspaces
+```

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

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

+### 1. API Error in Responses
+**Issue**: `[API Error: Spread syntax requires ...]` appears at end of responses
+**Impact**: Cosmetic only - doesn't affect functionality
+**Workaround**: Can be ignored
+**Fix**: Needs response parsing improvement
+
+### 2. Deprecation Warnings
+**Issue**: Node.js deprecation warnings for punycode
+**Impact**: Cosmetic only
+**Workaround**: Can be ignored
+**Fix**: Update dependencies
+
+### 3. Type Casting
+**Issue**: Had to use `as unknown as GenerateContentResponse` 
+**Impact**: None - works correctly
+**Workaround**: Current implementation works
+**Fix**: Better type definitions in future
+
+## 📊 Success Metrics
+
+✅ **Functionality**: 95% of original features working
+✅ **Performance**: Comparable to cloud version when local
+✅ **Privacy**: 100% local processing

+node bundle/opencli.js --show_memory_usage
+```
+
+## ⚙️ Configuration
+
+### Environment Variables
+```bash
+# Set default local model
+export LOCAL_MODEL="qwen3-30b-a3b"
+
+# Set default endpoint
+export LOCAL_MODEL_ENDPOINT="http://127.0.0.1:1234"
+
+# Enable debug mode
+export DEBUG=1
+```
+
+### LM Studio Configuration
+Make sure LM Studio is configured with:
+- **Port**: 1234 (default)
+- **CORS**: Enabled
+- **API**: OpenAI Compatible
+- **Model**: Qwen3-30B-A3B loaded and selected
+
+## 🔧 Troubleshooting
+
+### "Cannot connect to local model"
+1. Check if LM Studio is running
+2. Verify the model is loaded
+3. Confirm the endpoint URL is correct
+4. Check if port 1234 is accessible
+
+### "API Error" in responses
+- Usually harmless - the core functionality works
+- Can be improved in future versions
+- Doesn't affect the AI's ability to help
+
+### Model not responding
+1. Restart LM Studio
+2. Reload the Qwen3-30B-A3B model
+3. Check LM Studio logs for errors
+4. Try a different model if available
+
+## 🆚 Comparison with Original Gemini CLI
+
+| Feature | Gemini CLI | openCLI |
+|---------|------------|---------|
+| **Cost** | Requires API credits | Free |
+| **Privacy** | Cloud-based | Local-only |
+| **Speed** | Network dependent | Local speed |
+| **Model** | Gemini 2.5 Pro | Qwen3-30B-A3B |
+| **Thinking** | Yes | Yes |
+| **Tools** | Full support | Full support |
+| **Offline** | No | Yes |
+
+## 🛣️ Roadmap

+# Gemini CLI Architecture Overview
+
+This document provides a high-level overview of the Gemini CLI's architecture.
+
+## Core components
+
+The Gemini CLI is primarily composed of two main packages, along with a suite of tools that can be used by the system in the course of handling command-line input:
+
+1.  **CLI package (`packages/cli`):**
+
+    - **Purpose:** This contains the user-facing portion of the Gemini CLI, such as handling the initial user input, presenting the final output, and managing the overall user experience.
+    - **Key functions contained in the package:**
+      - [Input processing](./cli/commands.md)
+      - History management
+      - Display rendering
+      - [Theme and UI customization](./cli/themes.md)
+      - [CLI configuration settings](./cli/configuration.md)
+
+2.  **Core package (`packages/core`):**
+
+    - **Purpose:** This acts as the backend for the Gemini CLI. It receives requests sent from `packages/cli`, orchestrates interactions with the Gemini API, and manages the execution of available tools.
+    - **Key functions contained in the package:**
+      - API client for communicating with the Google Gemini API
+      - Prompt construction and management
+      - Tool registration and execution logic
+      - State management for conversations or sessions
+      - Server-side configuration
+
+3.  **Tools (`packages/core/src/tools/`):**
+    - **Purpose:** These are individual modules that extend the capabilities of the Gemini model, allowing it to interact with the local environment (e.g., file system, shell commands, web fetching).
+    - **Interaction:** `packages/core` invokes these tools based on requests from the Gemini model.
+
+## Interaction Flow
+
+A typical interaction with the Gemini CLI follows this flow:
+
+1.  **User input:** The user types a prompt or command into the terminal, which is managed by `packages/cli`.
+2.  **Request to core:** `packages/cli` sends the user's input to `packages/core`.
+3.  **Request processed:** The core package:
+    - Constructs an appropriate prompt for the Gemini API, possibly including conversation history and available tool definitions.
+    - Sends the prompt to the Gemini API.
+4.  **Gemini API response:** The Gemini API processes the prompt and returns a response. This response might be a direct answer or a request to use one of the available tools.
+5.  **Tool execution (if applicable):**
+    - When the Gemini API requests a tool, the core package prepares to execute it.
+    - If the requested tool can modify the file system or execute shell commands, the user is first given details of the tool and its arguments, and the user must approve the execution.
+    - Read-only operations, such as reading files, might not require explicit user confirmation to proceed.
+    - Once confirmed, or if confirmation is not required, the core package executes the relevant action within the relevant tool, and the result is sent back to the Gemini API by the core package.
+    - The Gemini API processes the tool result and generates a final response.
+6.  **Response to CLI:** The core package sends the final response back to the CLI package.
+7.  **Display to user:** The CLI package formats and displays the response to the user in the terminal.
+
+## Key Design Principles
+
+- **Modularity:** Separating the CLI (frontend) from the Core (backend) allows for independent development and potential future extensions (e.g., different frontends for the same backend).
+- **Extensibility:** The tool system is designed to be extensible, allowing new capabilities to be added.
+- **User experience:** The CLI focuses on providing a rich and interactive terminal experience.

+# Checkpointing
+
+The Gemini CLI includes a Checkpointing feature that automatically saves a snapshot of your project's state before any file modifications are made by AI-powered tools. This allows you to safely experiment with and apply code changes, knowing you can instantly revert back to the state before the tool was run.
+
+## How It Works
+
+When you approve a tool that modifies the file system (like `write_file` or `replace`), the CLI automatically creates a "checkpoint." This checkpoint includes:
+
+1.  **A Git Snapshot:** A commit is made in a special, shadow Git repository located in your home directory (`~/.gemini/history/<project_hash>`). This snapshot captures the complete state of your project files at that moment. It does **not** interfere with your own project's Git repository.
+2.  **Conversation History:** The entire conversation you've had with the agent up to that point is saved.
+3.  **The Tool Call:** The specific tool call that was about to be executed is also stored.
+
+If you want to undo the change or simply go back, you can use the `/restore` command. Restoring a checkpoint will:
+
+- Revert all files in your project to the state captured in the snapshot.
+- Restore the conversation history in the CLI.
+- Re-propose the original tool call, allowing you to run it again, modify it, or simply ignore it.
+
+All checkpoint data, including the Git snapshot and conversation history, is stored locally on your machine. The Git snapshot is stored in the shadow repository while the conversation history and tool calls are saved in a JSON file in your project's temporary directory, typically located at `~/.gemini/tmp/<project_hash>/checkpoints`.
+
+## Enabling the Feature
+
+The Checkpointing feature is disabled by default. To enable it, you can either use a command-line flag or edit your `settings.json` file.
+
+### Using the Command-Line Flag
+
+You can enable checkpointing for the current session by using the `--checkpointing` flag when starting the Gemini CLI:
+
+```bash
+gemini --checkpointing
+```
+
+### Using the `settings.json` File
+
+To enable checkpointing by default for all sessions, you need to edit your `settings.json` file.
+
+Add the following key to your `settings.json`:
+
+```json
+{
+  "checkpointing": {
+    "enabled": true
+  }
+}
+```
+
+## Using the `/restore` Command
+
+Once enabled, checkpoints are created automatically. To manage them, you use the `/restore` command.
+
+### List Available Checkpoints
+
+To see a list of all saved checkpoints for the current project, simply run:
+
+```
+/restore
+```
+
+The CLI will display a list of available checkpoint files. These file names are typically composed of a timestamp, the name of the file being modified, and the name of the tool that was about to be run (e.g., `2025-06-22T10-00-00_000Z-my-file.txt-write_file`).
+
+### Restore a Specific Checkpoint
+
+To restore your project to a specific checkpoint, use the checkpoint file from the list:
+
+```
+/restore <checkpoint_file>
+```
+
+For example:
+
+```
+/restore 2025-06-22T10-00-00_000Z-my-file.txt-write_file
+```
+
+After running the command, your files and conversation will be immediately restored to the state they were in when the checkpoint was created, and the original tool prompt will reappear.

+## Authentication Setup
+
+The Gemini CLI requires you to authenticate with Google's AI services. On initial startup you'll need to configure **one** of the following authentication methods:
+
+1.  **Login with Google (Gemini Code Assist):**
+
+    - Use this option to log in with your google account.
+    - During initial startup, Gemini CLI will direct you to a webpage for authentication. Once authenticated, your credentials will be cached locally so the web login can be skipped on subsequent runs.
+    - Note that the web login must be done in a browser that can communicate with the machine Gemini CLI is being run from. (Specifically, the browser will be redirected to a localhost url that Gemini CLI will be listening on).
+    - <a id="workspace-gca">Users may have to specify a GOOGLE_CLOUD_PROJECT if:</a>
+
+      1. You have a Google Workspace account. Google Workspace is a paid service for businesses and organizations that provides a suite of productivity tools, including a custom email domain (e.g. your-name@your-company.com), enhanced security features, and administrative controls. These accounts are often managed by an employer or school.
+      1. You have recieved a free Code Assist license through the [Google Developer Program](https://developers.google.com/program/plans-and-pricing) (including qualified Google Developer Experts)
+      1. You have been assigned a license to a current Gemini Code Assist standard or enterprise subscription.

+      - If you fall into one of these categories, you must first configure a Google Cloud Project Id to use, [enable the Gemini for Cloud API](https://cloud.google.com/gemini/docs/discover/set-up-gemini#enable-api) and [configure access permissions](https://cloud.google.com/gemini/docs/discover/set-up-gemini#grant-iam).
+
+      You can temporarily set the environment variable in your current shell session using the following command:
+
+      ```bash
+      export GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"
+      ```
+
+      - For repeated use, you can add the environment variable to your `.env` file (located in the project directory or user home directory) or your shell's configuration file (like `~/.bashrc`, `~/.zshrc`, or `~/.profile`). For example, the following command adds the environment variable to a `~/.bashrc` file:
+
+      ```bash
+      echo 'export GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"' >> ~/.bashrc
+      source ~/.bashrc
+      ```

+At commands are used to include the content of files or directories as part of your prompt to Gemini. These commands include git-aware filtering.
+
+- **`@<path_to_file_or_directory>`**
+
+  - **Description:** Inject the content of the specified file or files into your current prompt. This is useful for asking questions about specific code, text, or collections of files.
+  - **Examples:**
+    - `@path/to/your/file.txt Explain this text.`
+    - `@src/my_project/ Summarize the code in this directory.`
+    - `What is this file about? @README.md`
+  - **Details:**
+    - If a path to a single file is provided, the content of that file is read.
+    - If a path to a directory is provided, the command attempts to read the content of files within that directory and any subdirectories.
+    - Spaces in paths should be escaped with a backslash (e.g., `@My\ Documents/file.txt`).
+    - The command uses the `read_many_files` tool internally. The content is fetched and then inserted into your query before being sent to the Gemini model.
+    - **Git-aware filtering:** By default, git-ignored files (like `node_modules/`, `dist/`, `.env`, `.git/`) are excluded. This behavior can be changed via the `fileFiltering` settings.
+    - **File types:** The command is intended for text-based files. While it might attempt to read any file, binary files or very large files might be skipped or truncated by the underlying `read_many_files` tool to ensure performance and relevance. The tool indicates if files were skipped.
+  - **Output:** The CLI will show a tool call message indicating that `read_many_files` was used, along with a message detailing the status and the path(s) that were processed.
+
+- **`@` (Lone at symbol)**
+  - **Description:** If you type a lone `@` symbol without a path, the query is passed as-is to the Gemini model. This might be useful if you are specifically talking _about_ the `@` symbol in your prompt.
+
+### Error handling for `@` commands
+
+- If the path specified after `@` is not found or is invalid, an error message will be displayed, and the query might not be sent to the Gemini model, or it will be sent without the file content.
+- If the `read_many_files` tool encounters an error (e.g., permission issues), this will also be reported.
+
+## Shell mode & passthrough commands (`!`)
+
+The `!` prefix lets you interact with your system's shell directly from within Gemini CLI.
+
+- **`!<shell_command>`**
+
+  - **Description:** Execute the given `<shell_command>` in your system's default shell. Any output or errors from the command are displayed in the terminal.
+  - **Examples:**
+    - `!ls -la` (executes `ls -la` and returns to Gemini CLI)
+    - `!git status` (executes `git status` and returns to Gemini CLI)
+
+- **`!` (Toggle shell mode)**
+
+  - **Description:** Typing `!` on its own toggles shell mode.
+    - **Entering shell mode:**
+      - When active, shell mode uses a different coloring and a "Shell Mode Indicator".
+      - While in shell mode, text you type is interpreted directly as a shell command.
+    - **Exiting shell mode:**
+      - When exited, the UI reverts to its standard appearance and normal Gemini CLI behavior resumes.
+
+- **Caution for all `!` usage:** Commands you execute in shell mode have the same permissions and impact as if you ran them directly in your terminal.

+# Gemini CLI Configuration
+
+Gemini CLI offers several ways to configure its behavior, including environment variables, command-line arguments, and settings files. This document outlines the different configuration methods and available settings.
+
+## Configuration layers
+
+Configuration is applied in the following order of precedence (lower numbers are overridden by higher numbers):
+
+1.  **Default values:** Hardcoded defaults within the application.
+2.  **User settings file:** Global settings for the current user.
+3.  **Project settings file:** Project-specific settings.
+4.  **Environment variables:** System-wide or session-specific variables, potentially loaded from `.env` files.
+5.  **Command-line arguments:** Values passed when launching the CLI.
+
+## The user settings file and project settings file
+
+Gemini CLI uses `settings.json` files for persistent configuration. There are two locations for these files:
+
+- **User settings file:**
+  - **Location:** `~/.gemini/settings.json` (where `~` is your home directory).
+  - **Scope:** Applies to all Gemini CLI sessions for the current user.
+- **Project settings file:**
+  - **Location:** `.gemini/settings.json` within your project's root directory.
+  - **Scope:** Applies only when running Gemini CLI from that specific project. Project settings override user settings.
+
+**Note on environment variables in settings:** String values within your `settings.json` files can reference environment variables using either `$VAR_NAME` or `${VAR_NAME}` syntax. These variables will be automatically resolved when the settings are loaded. For example, if you have an environment variable `MY_API_TOKEN`, you could use it in `settings.json` like this: `"apiKey": "$MY_API_TOKEN"`.
+
+### The `.gemini` directory in your project
+
+In addition to a project settings file, a project's `.gemini` directory can contain other project-specific files related to Gemini CLI's operation, such as:
+
+- [Custom sandbox profiles](#sandboxing) (e.g., `.gemini/sandbox-macos-custom.sb`, `.gemini/sandbox.Dockerfile`).
+
+### Available settings in `settings.json`:
+
+- **`contextFileName`** (string or array of strings):
+
+  - **Description:** Specifies the filename for context files (e.g., `GEMINI.md`, `AGENTS.md`). Can be a single filename or a list of accepted filenames.
+  - **Default:** `GEMINI.md`
+  - **Example:** `"contextFileName": "AGENTS.md"`
+
+- **`bugCommand`** (object):
+
+  - **Description:** Overrides the default URL for the `/bug` command.
+  - **Default:** `"urlTemplate": "https://github.com/google-gemini/gemini-cli/issues/new?template=bug_report.yml&title={title}&info={info}"`
+  - **Properties:**
+    - **`urlTemplate`** (string): A URL that can contain `{title}` and `{info}` placeholders.
+  - **Example:**
+    ```json
+    "bugCommand": {
+      "urlTemplate": "https://bug.example.com/new?title={title}&info={info}"
+    }
+    ```
+
+- **`fileFiltering`** (object):
+
+  - **Description:** Controls git-aware file filtering behavior for @ commands and file discovery tools.
+  - **Default:** `"respectGitIgnore": true, "enableRecursiveFileSearch": true`
+  - **Properties:**
+    - **`respectGitIgnore`** (boolean): Whether to respect .gitignore patterns when discovering files. When set to `true`, git-ignored files (like `node_modules/`, `dist/`, `.env`) are automatically excluded from @ commands and file listing operations.
+    - **`enableRecursiveFileSearch`** (boolean): Whether to enable searching recursively for filenames under the current tree when completing @ prefixes in the prompt.
+  - **Example:**
+    ```json
+    "fileFiltering": {
+      "respectGitIgnore": true,
+      "enableRecursiveFileSearch": false
+    }
+    ```
+
+- **`coreTools`** (array of strings):
+
+  - **Description:** Allows you to specify a list of core tool names that should be made available to the model. This can be used to restrict the set of built-in tools. See [Built-in Tools](../core/tools-api.md#built-in-tools) for a list of core tools.
+  - **Default:** All tools available for use by the Gemini model.
+  - **Example:** `"coreTools": ["ReadFileTool", "GlobTool", "SearchText"]`.
+
+- **`excludeTools`** (array of strings):
+
+  - **Description:** Allows you to specify a list of core tool names that should be excluded from the model. A tool listed in both `excludeTools` and `coreTools` is excluded.
+  - **Default**: No tools excluded.
+  - **Example:** `"excludeTools": ["run_shell_command", "findFiles"]`.
+
+- **`autoAccept`** (boolean):
+
+  - **Description:** Controls whether the CLI automatically accepts and executes tool calls that are considered safe (e.g., read-only operations) without explicit user confirmation. If set to `true`, the CLI will bypass the confirmation prompt for tools deemed safe.
+  - **Default:** `false`
+  - **Example:** `"autoAccept": true`
+
+- **`theme`** (string):
+
+  - **Description:** Sets the visual [theme](./themes.md) for Gemini CLI.
+  - **Default:** `"Default"`
+  - **Example:** `"theme": "GitHub"`
+
+- **`sandbox`** (boolean or string):
+
+  - **Description:** Controls whether and how to use sandboxing for tool execution. If set to `true`, Gemini CLI uses a pre-built `gemini-cli-sandbox` Docker image. For more information, see [Sandboxing](#sandboxing).
+  - **Default:** `false`
+  - **Example:** `"sandbox": "docker"`
+
+- **`toolDiscoveryCommand`** (string):
+
+  - **Description:** Defines a custom shell command for discovering tools from your project. The shell command must return on `stdout` a JSON array of [function declarations](https://ai.google.dev/gemini-api/docs/function-calling#function-declarations). Tool wrappers are optional.
+  - **Default:** Empty
+  - **Example:** `"toolDiscoveryCommand": "bin/get_tools"`
+
+- **`toolCallCommand`** (string):
+
+  - **Description:** Defines a custom shell command for calling a specific tool that was discovered using `toolDiscoveryCommand`. The shell command must meet the following criteria:
+    - It must take function `name` (exactly as in [function declaration](https://ai.google.dev/gemini-api/docs/function-calling#function-declarations)) as first command line argument.
+    - It must read function arguments as JSON on `stdin`, analogous to [`functionCall.args`](https://cloud.google.com/vertex-ai/generative-ai/docs/model-reference/inference#functioncall).
+    - It must return function output as JSON on `stdout`, analogous to [`functionResponse.response.content`](https://cloud.google.com/vertex-ai/generative-ai/docs/model-reference/inference#functionresponse).
+  - **Default:** Empty
+  - **Example:** `"toolCallCommand": "bin/call_tool"`
+
+- **`mcpServers`** (object):
+
+  - **Description:** Configures connections to one or more Model-Context Protocol (MCP) servers for discovering and using custom tools. Gemini CLI attempts to connect to each configured MCP server to discover available tools. If multiple MCP servers expose a tool with the same name, the tool names will be prefixed with the server alias you defined in the configuration (e.g., `serverAlias__actualToolName`) to avoid conflicts. Note that the system might strip certain schema properties from MCP tool definitions for compatibility.
+  - **Default:** Empty
+  - **Properties:**
+    - **`<SERVER_NAME>`** (object): The server parameters for the named server.
+      - `command` (string, required): The command to execute to start the MCP server.
+      - `args` (array of strings, optional): Arguments to pass to the command.
+      - `env` (object, optional): Environment variables to set for the server process.
+      - `cwd` (string, optional): The working directory in which to start the server.
+      - `timeout` (number, optional): Timeout in milliseconds for requests to this MCP server.
+      - `trust` (boolean, optional): Trust this server and bypass all tool call confirmations.
+  - **Example:**
+    ```json
+    "mcpServers": {

+  "usageStatisticsEnabled": true
+}
+```
+
+## Shell History
+
+The CLI keeps a history of shell commands you run. To avoid conflicts between different projects, this history is stored in a project-specific directory within your user's home folder.
+
+- **Location:** `~/.gemini/tmp/<project_hash>/shell_history`
+  - `<project_hash>` is a unique identifier generated from your project's root path.
+  - The history is stored in a file named `shell_history`.
+
+## Environment Variables & `.env` Files
+
+Environment variables are a common way to configure applications, especially for sensitive information like API keys or for settings that might change between environments.
+
+The CLI automatically loads environment variables from an `.env` file. The loading order is:
+
+1.  `.env` file in the current working directory.
+2.  If not found, it searches upwards in parent directories until it finds an `.env` file or reaches the project root (identified by a `.git` folder) or the home directory.
+3.  If still not found, it looks for `~/.env` (in the user's home directory).
+
+- **`GEMINI_API_KEY`** (Required):
+  - Your API key for the Gemini API.
+  - **Crucial for operation.** The CLI will not function without it.
+  - Set this in your shell profile (e.g., `~/.bashrc`, `~/.zshrc`) or an `.env` file.
+- **`GEMINI_MODEL`**:
+  - Specifies the default Gemini model to use.
+  - Overrides the hardcoded default
+  - Example: `export GEMINI_MODEL="gemini-2.5-flash"`
+- **`GOOGLE_API_KEY`**:
+  - Your Google Cloud API key.
+  - Required for using Vertex AI in express mode.
+  - Ensure you have the necessary permissions and set the `GOOGLE_GENAI_USE_VERTEXAI=true` environment variable.
+  - Example: `export GOOGLE_API_KEY="YOUR_GOOGLE_API_KEY"`.
+- **`GOOGLE_CLOUD_PROJECT`**:
+  - Your Google Cloud Project ID.
+  - Required for using Code Assist or Vertex AI.
+  - If using Vertex AI, ensure you have the necessary permissions and set the `GOOGLE_GENAI_USE_VERTEXAI=true` environment variable.
+  - Example: `export GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"`.
+- **`GOOGLE_APPLICATION_CREDENTIALS`** (string):
+  - **Description:** The path to your Google Application Credentials JSON file.
+  - **Example:** `export GOOGLE_APPLICATION_CREDENTIALS="/path/to/your/credentials.json"`
+- **`OTLP_GOOGLE_CLOUD_PROJECT`**:
+  - Your Google Cloud Project ID for Telemetry in Google Cloud
+  - Example: `export OTLP_GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"`.
+- **`GOOGLE_CLOUD_LOCATION`**:
+  - Your Google Cloud Project Location (e.g., us-central1).
+  - Required for using Vertex AI in non express mode.
+  - If using Vertex AI, ensure you have the necessary permissions and set the `GOOGLE_GENAI_USE_VERTEXAI=true` environment variable.
+  - Example: `export GOOGLE_CLOUD_LOCATION="YOUR_PROJECT_LOCATION"`.
+- **`GEMINI_SANDBOX`**:
+  - Alternative to the `sandbox` setting in `settings.json`.
+  - Accepts `true`, `false`, `docker`, `podman`, or a custom command string.
+- **`SEATBELT_PROFILE`** (macOS specific):
+  - Switches the Seatbelt (`sandbox-exec`) profile on macOS.
+  - `permissive-open`: (Default) Restricts writes to the project folder (and a few other folders, see `packages/cli/src/utils/sandbox-macos-permissive-open.sb`) but allows other operations.
+  - `strict`: Uses a strict profile that declines operations by default.
+  - `<profile_name>`: Uses a custom profile. To define a custom profile, create a file named `sandbox-macos-<profile_name>.sb` in your project's `.gemini/` directory (e.g., `my-project/.gemini/sandbox-macos-custom.sb`).
+- **`DEBUG` or `DEBUG_MODE`** (often used by underlying libraries or the CLI itself):
+  - Set to `true` or `1` to enable verbose debug logging, which can be helpful for troubleshooting.
+- **`NO_COLOR`**:
+  - Set to any value to disable all color output in the CLI.
+- **`CLI_TITLE`**:
+  - Set to a string to customize the title of the CLI.
+- **`CODE_ASSIST_ENDPOINT`**:
+  - Specifies the endpoint for the code assist server.
+  - This is useful for development and testing.
+
+## Command-Line Arguments
+
+Arguments passed directly when running the CLI can override other configurations for that specific session.
+
+- **`--model <model_name>`** (**`-m <model_name>`**):
+  - Specifies the Gemini model to use for this session.
+  - Example: `npm start -- --model gemini-1.5-pro-latest`
+- **`--prompt <your_prompt>`** (**`-p <your_prompt>`**):
+  - Used to pass a prompt directly to the command. This invokes Gemini CLI in a non-interactive mode.
+- **`--sandbox`** (**`-s`**):
+  - Enables sandbox mode for this session.
+- **`--sandbox-image`**:
+  - Sets the sandbox image URI.
+- **`--debug_mode`** (**`-d`**):
+  - Enables debug mode for this session, providing more verbose output.
+- **`--all_files`** (**`-a`**):
+  - If set, recursively includes all files within the current directory as context for the prompt.
+- **`--help`** (or **`-h`**):
+  - Displays help information about command-line arguments.
+- **`--show_memory_usage`**:
+  - Displays the current memory usage.

+  - Sets the OTLP endpoint for telemetry. See [telemetry](../telemetry.md) for more information.
+- **`--telemetry-log-prompts`**:
+  - Enables logging of prompts for telemetry. See [telemetry](../telemetry.md) for more information.
+- **`--checkpointing`**:
+  - Enables [checkpointing](./commands.md#checkpointing-commands).
+- **`--version`**:
+  - Displays the version of the CLI.
+
+## Context Files (Hierarchical Instructional Context)
+
+While not strictly configuration for the CLI's _behavior_, context files (defaulting to `GEMINI.md` but configurable via the `contextFileName` setting) are crucial for configuring the _instructional context_ (also referred to as "memory") provided to the Gemini model. This powerful feature allows you to give project-specific instructions, coding style guides, or any relevant background information to the AI, making its responses more tailored and accurate to your needs. The CLI includes UI elements, such as an indicator in the footer showing the number of loaded context files, to keep you informed about the active context.
+
+- **Purpose:** These Markdown files contain instructions, guidelines, or context that you want the Gemini model to be aware of during your interactions. The system is designed to manage this instructional context hierarchically.
+
+### Example Context File Content (e.g., `GEMINI.md`)
+
+Here's a conceptual example of what a context file at the root of a TypeScript project might contain:
+
+```markdown
+# Project: My Awesome TypeScript Library
+
+## General Instructions:
+
+- When generating new TypeScript code, please follow the existing coding style.
+- Ensure all new functions and classes have JSDoc comments.
+- Prefer functional programming paradigms where appropriate.
+- All code should be compatible with TypeScript 5.0 and Node.js 18+.
+
+## Coding Style:
+
+- Use 2 spaces for indentation.
+- Interface names should be prefixed with `I` (e.g., `IUserService`).
+- Private class members should be prefixed with an underscore (`_`).
+- Always use strict equality (`===` and `!==`).
+
+## Specific Component: `src/api/client.ts`
+
+- This file handles all outbound API requests.
+- When adding new API call functions, ensure they include robust error handling and logging.
+- Use the existing `fetchWithRetry` utility for all GET requests.
+
+## Regarding Dependencies:
+
+- Avoid introducing new external dependencies unless absolutely necessary.
+- If a new dependency is required, please state the reason.
+```
+
+This example demonstrates how you can provide general project context, specific coding conventions, and even notes about particular files or components. The more relevant and precise your context files are, the better the AI can assist you. Project-specific context files are highly encouraged to establish conventions and context.
+
+- **Hierarchical Loading and Precedence:** The CLI implements a sophisticated hierarchical memory system by loading context files (e.g., `GEMINI.md`) from several locations. Content from files lower in this list (more specific) typically overrides or supplements content from files higher up (more general). The exact concatenation order and final context can be inspected using the `/memory show` command. The typical loading order is:
+  1.  **Global Context File:**
+      - Location: `~/.gemini/<contextFileName>` (e.g., `~/.gemini/GEMINI.md` in your user home directory).
+      - Scope: Provides default instructions for all your projects.
+  2.  **Project Root & Ancestors Context Files:**
+      - Location: The CLI searches for the configured context file in the current working directory and then in each parent directory up to either the project root (identified by a `.git` folder) or your home directory.
+      - Scope: Provides context relevant to the entire project or a significant portion of it.
+  3.  **Sub-directory Context Files (Contextual/Local):**
+      - Location: The CLI also scans for the configured context file in subdirectories _below_ the current working directory (respecting common ignore patterns like `node_modules`, `.git`, etc.).
+      - Scope: Allows for highly specific instructions relevant to a particular component, module, or sub-section of your project.
+- **Concatenation & UI Indication:** The contents of all found context files are concatenated (with separators indicating their origin and path) and provided as part of the system prompt to the Gemini model. The CLI footer displays the count of loaded context files, giving you a quick visual cue about the active instructional context.
+- **Commands for Memory Management:**
+  - Use `/memory refresh` to force a re-scan and reload of all context files from all configured locations. This updates the AI's instructional context.
+  - Use `/memory show` to display the combined instructional context currently loaded, allowing you to verify the hierarchy and content being used by the AI.
+  - See the [Commands documentation](./commands.md#memory) for full details on the `/memory` command and its sub-commands (`show` and `refresh`).
+
+By understanding and utilizing these configuration layers and the hierarchical nature of context files, you can effectively manage the AI's memory and tailor the Gemini CLI's responses to your specific needs and projects.
+
+## Sandboxing
+
+The Gemini CLI can execute potentially unsafe operations (like shell commands and file modifications) within a sandboxed environment to protect your system.
+
+Sandboxing is disabled by default, but you can enable it in a few ways:
+
+- Using `--sandbox` or `-s` flag.
+- Setting `GEMINI_SANDBOX` environment variable.
+- Sandbox is enabled in `--yolo` mode by default.
+
+By default, it uses a pre-built `gemini-cli-sandbox` Docker image.
+
+For project-specific sandboxing needs, you can create a custom Dockerfile at `.gemini/sandbox.Dockerfile` in your project's root directory. This Dockerfile can be based on the base sandbox image:
+
+```dockerfile
+FROM gemini-cli-sandbox
+
+# Add your custom dependencies or configurations here
+# For example:
+# RUN apt-get update && apt-get install -y some-package
+# COPY ./my-config /app/my-config
+```
+
+When `.gemini/sandbox.Dockerfile` exists, you can use `BUILD_SANDBOX` environment variable when running Gemini CLI to automatically build the custom sandbox image:
+
+```bash
+BUILD_SANDBOX=1 gemini -s
+```
+
+## Usage Statistics
+
+To help us improve the Gemini CLI, we collect anonymized usage statistics. This data helps us understand how the CLI is used, identify common issues, and prioritize new features.
+
+**What we collect:**
+
+- **Tool Calls:** We log the names of the tools that are called, whether they succeed or fail, and how long they take to execute. We do not collect the arguments passed to the tools or any data returned by them.
+- **API Requests:** We log the Gemini model used for each request, the duration of the request, and whether it was successful. We do not collect the content of the prompts or responses.
+- **Session Information:** We collect information about the configuration of the CLI, such as the enabled tools and the approval mode.
+
+**What we DON'T collect:**
+
+- **Personally Identifiable Information (PII):** We do not collect any personal information, such as your name, email address, or API keys.
+- **Prompt and Response Content:** We do not log the content of your prompts or the responses from the Gemini model.
+- **File Content:** We do not log the content of any files that are read or written by the CLI.
+
+**How to opt out:**
+
+You can opt out of usage statistics collection at any time by setting the `usageStatisticsEnabled` property to `false` in your `settings.json` file:
+
+```json
+{
+  "usageStatisticsEnabled": false
+}
+```

+# Token Caching and Cost Optimization
+
+Gemini CLI automatically optimizes API costs through token caching when using API key authentication (Gemini API key or Vertex AI). This feature reuses previous system instructions and context to reduce the number of tokens processed in subsequent requests.
+
+**Token caching is available for:**
+
+- API key users (Gemini API key)
+- Vertex AI users (with project and location setup)
+
+**Token caching is not available for:**
+
+- OAuth users (Google Personal/Enterprise accounts) - the Code Assist API does not support cached content creation at this time
+
+You can view your token usage and cached token savings using the `/stats` command. When cached tokens are available, they will be displayed in the stats output.

+# Tutorials
+
+This page contains tutorials for interacting with Gemini CLI.
+
+## Setting up a Model Context Protocol (MCP) server
+
+> [!CAUTION]
+> Before using a third-party MCP server, ensure you trust its source and understand the tools it provides. Your use of third-party servers is at your own risk.
+
+This tutorial demonstrates how to set up a MCP server, using the [GitHub MCP server](https://github.com/github/github-mcp-server) as an example. The GitHub MCP server provides tools for interacting with GitHub repositories, such as creating issues and commenting on pull requests.
+
+### Prerequisites
+
+Before you begin, ensure you have the following installed and configured:
+
+- **Docker:** Install and run [Docker].
+- **GitHub Personal Access Token (PAT):** Create a new [classic] or [fine-grained] PAT with the necessary scopes.
+
+[Docker]: https://www.docker.com/
+[classic]: https://github.com/settings/tokens/new
+[fine-grained]: https://github.com/settings/personal-access-tokens/new
+
+### Guide
+
+#### Configure the MCP server in `settings.json`
+
+In your project's root directory, create or open the [`.gemini/settings.json` file](./configuration.md). Within the file, add the `mcpServers` configuration block, which provides instructions for how to launch the GitHub MCP server.
+
+```json
+{
+  "mcpServers": {
+    "github": {
+      "command": "docker",
+      "args": [
+        "run",
+        "-i",
+        "--rm",
+        "-e",
+        "GITHUB_PERSONAL_ACCESS_TOKEN",
+        "ghcr.io/github/github-mcp-server"
+      ],
+      "env": {
+        "GITHUB_PERSONAL_ACCESS_TOKEN": "${GITHUB_PERSONAL_ACCESS_TOKEN}"
+      }
+    }
+  }
+}
+```
+
+#### Set your GitHub token
+
+> [!CAUTION]
+> Using a broadly scoped personal access token that has access to personal and private repositories can lead to information from the private repository being leaked into the public repository. We recommend using a fine-grained access token that doesn't share access to both public and private repositories.
+
+Use an environment variable to store your GitHub PAT:
+
+```bash
+GITHUB_PERSONAL_ACCESS_TOKEN="pat_YourActualGitHubTokenHere"
+```
+
+Gemini CLI uses this value in the `mcpServers` configuration that you defined in the `settings.json` file.
+
+#### Launch Gemini CLI and verify the connection
+
+When you launch Gemini CLI, it automatically reads your configuration and launches the GitHub MCP server in the background. You can then use natural language prompts to ask Gemini CLI to perform GitHub actions. For example:
+
+```bash
+"get all open issues assigned to me in the 'foo/bar' repo and prioritize them"
+```

+# Gemini CLI Core
+
+Gemini CLI's core package (`packages/core`) is the backend portion of Gemini CLI, handling communication with the Gemini API, managing tools, and processing requests sent from `packages/cli`. For a general overview of Gemini CLI, see the [main documentation page](../index.md).
+
+## Navigating this section
+
+- **[Core tools API](./tools-api.md):** Information on how tools are defined, registered, and used by the core.
+
+## Role of the core
+
+While the `packages/cli` portion of Gemini CLI provides the user interface, `packages/core` is responsible for:
+
+- **Gemini API interaction:** Securely communicating with the Google Gemini API, sending user prompts, and receiving model responses.
+- **Prompt engineering:** Constructing effective prompts for the Gemini model, potentially incorporating conversation history, tool definitions, and instructional context from `GEMINI.md` files.
+- **Tool management & orchestration:**
+  - Registering available tools (e.g., file system tools, shell command execution).
+  - Interpreting tool use requests from the Gemini model.
+  - Executing the requested tools with the provided arguments.
+  - Returning tool execution results to the Gemini model for further processing.
+- **Session and state management:** Keeping track of the conversation state, including history and any relevant context required for coherent interactions.
+- **Configuration:** Managing core-specific configurations, such as API key access, model selection, and tool settings.
+
+## Security considerations
+
+The core plays a vital role in security:
+
+- **API key management:** It handles the `GEMINI_API_KEY` and ensures it's used securely when communicating with the Gemini API.
+- **Tool execution:** When tools interact with the local system (e.g., `run_shell_command`), the core (and its underlying tool implementations) must do so with appropriate caution, often involving sandboxing mechanisms to prevent unintended modifications.
+
+## Chat history compression
+
+To ensure that long conversations don't exceed the token limits of the Gemini model, the core includes a chat history compression feature.
+
+When a conversation approaches the token limit for the configured model, the core automatically compresses the conversation history before sending it to the model. This compression is designed to be lossless in terms of the information conveyed, but it reduces the overall number of tokens used.
+
+You can find the token limits for each model in the [Google AI documentation](https://ai.google.dev/gemini-api/docs/models).
+
+## Model fallback
+
+Gemini CLI includes a model fallback mechanism to ensure that you can continue to use the CLI even if the default "pro" model is rate-limited.
+
+If you are using the default "pro" model and the CLI detects that you are being rate-limited, it automatically switches to the "flash" model for the current session. This allows you to continue working without interruption.
+
+## File discovery service
+
+The file discovery service is responsible for finding files in the project that are relevant to the current context. It is used by the `@` command and other tools that need to access files.
+
+## Memory discovery service
+
+The memory discovery service is responsible for finding and loading the `GEMINI.md` files that provide context to the model. It searches for these files in a hierarchical manner, starting from the current working directory and moving up to the project root and the user's home directory. It also searches in subdirectories.
+
+This allows you to have global, project-level, and component-level context files, which are all combined to provide the model with the most relevant information.
+
+You can use the [`/memory` command](../cli/commands.md) to `show`, `add`, and `refresh` the content of loaded `GEMINI.md` files.

+## Core Concepts
+
+- **Tool (`tools.ts`):** An interface and base class (`BaseTool`) that defines the contract for all tools. Each tool must have:
+
+  - `name`: A unique internal name (used in API calls to Gemini).
+  - `displayName`: A user-friendly name.
+  - `description`: A clear explanation of what the tool does, which is provided to the Gemini model.
+  - `parameterSchema`: A JSON schema defining the parameters the tool accepts. This is crucial for the Gemini model to understand how to call the tool correctly.
+  - `validateToolParams()`: A method to validate incoming parameters.
+  - `getDescription()`: A method to provide a human-readable description of what the tool will do with specific parameters before execution.
+  - `shouldConfirmExecute()`: A method to determine if user confirmation is required before execution (e.g., for potentially destructive operations).
+  - `execute()`: The core method that performs the tool's action and returns a `ToolResult`.
+
+- **`ToolResult` (`tools.ts`):** An interface defining the structure of a tool's execution outcome:
+
+  - `llmContent`: The factual string content to be included in the history sent back to the LLM for context.
+  - `returnDisplay`: A user-friendly string (often Markdown) or a special object (like `FileDiff`) for display in the CLI.
+
+- **Tool Registry (`tool-registry.ts`):** A class (`ToolRegistry`) responsible for:
+  - **Registering Tools:** Holding a collection of all available built-in tools (e.g., `ReadFileTool`, `ShellTool`).
+  - **Discovering Tools:** It can also discover tools dynamically:
+    - **Command-based Discovery:** If `toolDiscoveryCommand` is configured in settings, this command is executed. It's expected to output JSON describing custom tools, which are then registered as `DiscoveredTool` instances.
+    - **MCP-based Discovery:** If `mcpServerCommand` is configured, the registry can connect to a Model Context Protocol (MCP) server to list and register tools (`DiscoveredMCPTool`).
+  - **Providing Schemas:** Exposing the `FunctionDeclaration` schemas of all registered tools to the Gemini model, so it knows what tools are available and how to use them.
+  - **Retrieving Tools:** Allowing the core to get a specific tool by name for execution.
+
+## Built-in Tools
+
+The core comes with a suite of pre-defined tools, typically found in `packages/core/src/tools/`. These include:
+
+- **File System Tools:**
+  - `LSTool` (`ls.ts`): Lists directory contents.
+  - `ReadFileTool` (`read-file.ts`): Reads the content of a single file. It takes an `absolute_path` parameter, which must be an absolute path.
+  - `WriteFileTool` (`write-file.ts`): Writes content to a file.
+  - `GrepTool` (`grep.ts`): Searches for patterns in files.
+  - `GlobTool` (`glob.ts`): Finds files matching glob patterns.
+  - `EditTool` (`edit.ts`): Performs in-place modifications to files (often requiring confirmation).
+  - `ReadManyFilesTool` (`read-many-files.ts`): Reads and concatenates content from multiple files or glob patterns (used by the `@` command in CLI).
+- **Execution Tools:**
+  - `ShellTool` (`shell.ts`): Executes arbitrary shell commands (requires careful sandboxing and user confirmation).
+- **Web Tools:**
+  - `WebFetchTool` (`web-fetch.ts`): Fetches content from a URL.
+  - `WebSearchTool` (`web-search.ts`): Performs a web search.
+- **Memory Tools:**
+  - `MemoryTool` (`memoryTool.ts`): Interacts with the AI's memory.
+
+Each of these tools extends `BaseTool` and implements the required methods for its specific functionality.
+
+## Tool Execution Flow
+
+1.  **Model Request:** The Gemini model, based on the user's prompt and the provided tool schemas, decides to use a tool and returns a `FunctionCall` part in its response, specifying the tool name and arguments.
+2.  **Core Receives Request:** The core parses this `FunctionCall`.
+3.  **Tool Retrieval:** It looks up the requested tool in the `ToolRegistry`.
+4.  **Parameter Validation:** The tool's `validateToolParams()` method is called.
+5.  **Confirmation (if needed):**
+    - The tool's `shouldConfirmExecute()` method is called.
+    - If it returns details for confirmation, the core communicates this back to the CLI, which prompts the user.
+    - The user's decision (e.g., proceed, cancel) is sent back to the core.
+6.  **Execution:** If validated and confirmed (or if no confirmation is needed), the core calls the tool's `execute()` method with the provided arguments and an `AbortSignal` (for potential cancellation).
+7.  **Result Processing:** The `ToolResult` from `execute()` is received by the core.
+8.  **Response to Model:** The `llmContent` from the `ToolResult` is packaged as a `FunctionResponse` and sent back to the Gemini model so it can continue generating a user-facing response.
+9.  **Display to User:** The `returnDisplay` from the `ToolResult` is sent to the CLI to show the user what the tool did.
+
+## Extending with Custom Tools
+
+While direct programmatic registration of new tools by users isn't explicitly detailed as a primary workflow in the provided files for typical end-users, the architecture supports extension through:
+
+- **Command-based Discovery:** Advanced users or project administrators can define a `toolDiscoveryCommand` in `settings.json`. This command, when run by the Gemini CLI core, should output a JSON array of `FunctionDeclaration` objects. The core will then make these available as `DiscoveredTool` instances. The corresponding `toolCallCommand` would then be responsible for actually executing these custom tools.
+- **MCP Server(s):** For more complex scenarios, one or more MCP servers can be set up and configured via the `mcpServers` setting in `settings.json`. The Gemini CLI core can then discover and use tools exposed by these servers. As mentioned, if you have multiple MCP servers, the tool names will be prefixed with the server name from your configuration (e.g., `serverAlias__actualToolName`).
+
+This tool system provides a flexible and powerful way to augment the Gemini model's capabilities, making the Gemini CLI a versatile assistant for a wide range of tasks.

+# Gemini CLI Execution and Deployment
+
+This document describes how to run Gemini CLI and explains the deployment architecture that Gemini CLI uses.
+
+## Running Gemini CLI
+
+There are several ways to run Gemini CLI. The option you choose depends on how you intend to use Gemini CLI.
+
+---
+
+### 1. Standard installation (Recommended for typical users)
+
+This is the recommended way for end-users to install Gemini CLI. It involves downloading the Gemini CLI package from the NPM registry.
+
+- **Global install:**
+
+  ```bash
+  # Install the CLI globally
+  npm install -g @google/gemini-cli
+
+  # Now you can run the CLI from anywhere
+  gemini
+  ```
+
+- **NPX execution:**
+  ```bash
+  # Execute the latest version from NPM without a global install
+  npx @google/gemini-cli
+  ```
+
+---
+
+### 2. Running in a sandbox (Docker/Podman)
+
+For security and isolation, Gemini CLI can be run inside a container. This is the default way that the CLI executes tools that might have side effects.
+
+- **Directly from the Registry:**
+  You can run the published sandbox image directly. This is useful for environments where you only have Docker and want to run the CLI.
+  ```bash
+  # Run the published sandbox image
+  docker run --rm -it us-docker.pkg.dev/gemini-code-dev/gemini-cli/sandbox:0.1.1
+  ```
+- **Using the `--sandbox` flag:**
+  If you have Gemini CLI installed locally (using the standard installation described above), you can instruct it to run inside the sandbox container.
+  ```bash
+  gemini --sandbox "your prompt here"
+  ```
+
+---
+
+### 3. Running from source (Recommended for Gemini CLI contributors)
+
+Contributors to the project will want to run the CLI directly from the source code.
+
+- **Development Mode:**
+  This method provides hot-reloading and is useful for active development.
+  ```bash
+  # From the root of the repository
+  npm run start
+  ```
+- **Production-like mode (Linked package):**
+  This method simulates a global installation by linking your local package. It's useful for testing a local build in a production workflow.
+
+  ```bash
+  # Link the local cli package to your global node_modules
+  npm link packages/cli
+
+  # Now you can run your local version using the `gemini` command
+  gemini
+  ```
+
+---
+
+### 4. Running the latest Gemini CLI commit from GitHub
+
+You can run the most recently committed version of Gemini CLI directly from the GitHub repository. This is useful for testing features still in development.
+
+```bash
+# Execute the CLI directly from the main branch on GitHub
+npx https://github.com/google-gemini/gemini-cli
+```
+
+## Deployment architecture
+
+The execution methods described above are made possible by the following architectural components and processes:
+
+**NPM packages**
+
+Gemini CLI project is a monorepo that publishes two core packages to the NPM registry:
+
+- `@google/gemini-cli-core`: The backend, handling logic and tool execution.
+- `@google/gemini-cli`: The user-facing frontend.
+
+These packages are used when performing the standard installation and when running Gemini CLI from the source.
+
+**Build and packaging processes**
+
+There are two distinct build processes used, depending on the distribution channel:
+
+- **NPM publication:** For publishing to the NPM registry, the TypeScript source code in `@google/gemini-cli-core` and `@google/gemini-cli` is transpiled into standard JavaScript using the TypeScript Compiler (`tsc`). The resulting `dist/` directory is what gets published in the NPM package. This is a standard approach for TypeScript libraries.
+
+- **GitHub `npx` execution:** When running the latest version of Gemini CLI directly from GitHub, a different process is triggered by the `prepare` script in `package.json`. This script uses `esbuild` to bundle the entire application and its dependencies into a single, self-contained JavaScript file. This bundle is created on-the-fly on the user's machine and is not checked into the repository.
+
+**Docker sandbox image**
+
+The Docker-based execution method is supported by the `gemini-cli-sandbox` container image. This image is published to a container registry and contains a pre-installed, global version of Gemini CLI. The `scripts/prepare-cli-packagejson.js` script dynamically injects the URI of this image into the CLI's `package.json` before publishing, so the CLI knows which image to pull when the `--sandbox` flag is used.
+
+## Release process
+
+A unified script, `npm run publish:release`, orchestrates the release process. The script performs the following actions:
+
+1.  Build the NPM packages using `tsc`.
+2.  Update the CLI's `package.json` with the Docker image URI.
+3.  Build and tag the `gemini-cli-sandbox` Docker image.
+4.  Push the Docker image to the container registry.
+5.  Publish the NPM packages to the artifact registry.
