+# 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](/docs/cli/commands)
+      - History management
+      - Display rendering
+      - [Theme and UI customization](/docs/cli/themes)
+      - [CLI configuration settings](/docs/get-started/configuration)
+
+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.

+# Core concepts
+
+This guide explains the fundamental concepts and terminology used throughout the
+Gemini CLI ecosystem. Understanding these terms will help you make the most of
+the tool's capabilities.
+
+## Approval mode
+
+**Approval mode** determines the level of autonomy you grant to the agent when
+executing tools.
+
+- **Default:** The agent asks for confirmation before performing any potentially
+  impactful action (like writing files or running shell commands).
+- **Auto-edit:** File modifications are applied automatically, but shell
+  commands still require confirmation.
+- **YOLO (You Only Look Once):** The agent runs all tools without asking for
+  permission. High risk, high speed.
+
+## Checkpointing
+
+**Checkpointing** is a safety feature that automatically snapshots your
+project's file state before the agent performs any destructive action (like
+writing a file).
+
+- **Snapshots:** Stored in a hidden Git repository (separate from your project's
+  Git history).
+- **Restore:** Allows you to instantly revert changes if the agent makes a
+  mistake, using the `/restore` command.
+
+## Context
+
+**Context** refers to the information the agent has about your current task and
+environment. Gemini CLI provides context through several mechanisms:
+
+- **Conversation history:** The chat log of the current session.
+- **Project context (`GEMINI.md`):** Persistent instructions and rules defined
+  in your project's root or subdirectories.
+- **File content:** Files you explicitly reference (e.g., `@src/app.ts`) or that
+  the agent reads using tools.
+- **Environment:** Information about your operating system, shell, and working
+  directory.
+
+Effective context management is key to getting accurate and relevant responses.
+
+## Extension
+
+An **Extension** is a pluggable package that adds new capabilities to Gemini
+CLI. Extensions can bundle:
+
+- **Skills:** Specialized procedural knowledge.
+- **MCP Servers:** Connections to external tools and data.
+- **Commands:** Custom slash commands.
+
+## Headless mode
+
+**Headless mode** refers to running Gemini CLI without the interactive terminal
+UI (TUI). This is used for scripting, automation, and piping data into or out of
+the agent.
+
+- **Interactive:** `gemini` (starts the REPL).
+- **Headless:** `gemini "Fix this file"` (runs once and exits).
+
+## Hook
+
+A **Hook** is a script or function that intercepts specific lifecycle events in
+the CLI.
+
+- **Use cases:** Logging tool usage, validating user input, or modifying the
+  agent's system prompt dynamically.
+- **Lifecycle:** Hooks can run before or after the agent starts, before tools
+  are executed, or after the session ends.
+
+## Model Context Protocol (MCP)
+
+The **Model Context Protocol (MCP)** is an open standard that allows Gemini CLI
+to connect to external data sources and tools.
+
+- **MCP Server:** A lightweight application that exposes resources (data) and
+  tools (functions) to the CLI.
+- **Use case:** Connecting Gemini to a PostgreSQL database, a GitHub repository,
+  or a Slack workspace without building custom integration logic into the CLI
+  core.
+
+## Policy engine
+
+The **Policy Engine** is the security subsystem that enforces rules on tool
+execution. It evaluates every tool call against your configuration (e.g.,
+[Trusted folders](#trusted-folders), allowed commands) to decide whether to:
+
+- Allow the action immediately.
+- Require user confirmation.
+- Block the action entirely.
+
+## Sandboxing
+
+**Sandboxing** is an optional security mode that isolates the agent's execution
+environment. When enabled, the agent runs inside a secure container (e.g.,
+Docker), preventing it from accessing sensitive files or system resources
+outside of the designated workspace.
+
+## Session
+
+A **Session** is a single continuous interaction thread with the agent.
+
+- **State:** Sessions maintain conversation history and short-term memory.
+- **Persistence:** Sessions are automatically saved, allowing you to pause,
+  resume, or rewind them later.
+
+## Skill
+
+A **Skill** (or **Agent Skill**) is a package of specialized expertise that the
+agent can load on demand. Unlike general context, a skill provides specific
+procedural knowledge for a distinct task.
+
+- **Example:** A "Code Reviewer" skill might contain a checklist of security
+  vulnerabilities to look for and a specific format for reporting findings.
+- **Activation:** Skills are typically activated dynamically when the agent
+  recognizes a matching request.
+
+## Tool
+
+A **Tool** is a specific function or capability that the agent can execute.
+Tools allow the AI to interact with the outside world.
+
+- **Built-in tools:** Core capabilities like `read_file`, `run_shell_command`,
+  and `google_web_search`.
+- **MCP tools:** External tools provided by
+  [MCP servers](#model-context-protocol-mcp).
+
+When the agent uses a tool, it pauses generation, executes the code, and feeds
+the output back into its context window.
+
+## Trusted folders
+
+**Trusted folders** are specific directories you have explicitly authorized the
+agent to access without repeated confirmation prompts. This is a key component

+# Gemini CLI configuration
+
+**Note on deprecated configuration format**
+
+This document describes the legacy v1 format for the `settings.json` file. This
+format is now deprecated.
+
+- The new format will be supported in the stable release starting
+  **[09/10/25]**.
+- Automatic migration from the old format to the new format will begin on
+  **[09/17/25]**.
+
+For details on the new, recommended format, please see the
+[current Configuration documentation](./configuration.md).
+
+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.  **System defaults file:** System-wide default settings that can be
+    overridden by other settings files.
+3.  **User settings file:** Global settings for the current user.
+4.  **Project settings file:** Project-specific settings.
+5.  **System settings file:** System-wide settings that override all other
+    settings files.
+6.  **Environment variables:** System-wide or session-specific variables,
+    potentially loaded from `.env` files.
+7.  **Command-line arguments:** Values passed when launching the CLI.
+
+## Settings files
+
+Gemini CLI uses JSON settings files for persistent configuration. There are four
+locations for these files:
+
+- **System defaults file:**
+  - **Location:** `/etc/gemini-cli/system-defaults.json` (Linux),
+    `C:\ProgramData\gemini-cli\system-defaults.json` (Windows) or
+    `/Library/Application Support/GeminiCli/system-defaults.json` (macOS). The
+    path can be overridden using the `GEMINI_CLI_SYSTEM_DEFAULTS_PATH`
+    environment variable.
+  - **Scope:** Provides a base layer of system-wide default settings. These
+    settings have the lowest precedence and are intended to be overridden by
+    user, project, or system override settings.
+- **User settings file:**
+  - **Location:** `~/.gemini/settings.json` (where `~` is your home directory).
+  - **Scope:** Applies to all Gemini CLI sessions for the current user. User
+    settings override system defaults.
+- **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 and system defaults.
+- **System settings file:**
+  - **Location:** `/etc/gemini-cli/settings.json` (Linux),
+    `C:\ProgramData\gemini-cli\settings.json` (Windows) or
+    `/Library/Application Support/GeminiCli/settings.json` (macOS). The path can
+    be overridden using the `GEMINI_CLI_SYSTEM_SETTINGS_PATH` environment
+    variable.
+  - **Scope:** Applies to all Gemini CLI sessions on the system, for all users.
+    System settings act as overrides, taking precedence over all other settings
+    files. May be useful for system administrators at enterprises to have
+    controls over users' Gemini CLI setups.
+
+**Note on environment variables in settings:** String values within your
+`settings.json` files can reference environment variables using either
+`$VAR_NAME` or `${VAR_NAME}` syntax. These variables will be automatically
+resolved when the settings are loaded. For example, if you have an environment
+variable `MY_API_TOKEN`, you could use it in `settings.json` like this:
+`"apiKey": "$MY_API_TOKEN"`.
+
+> **Note for Enterprise Users:** For guidance on deploying and managing Gemini
+> CLI in a corporate environment, please see the
+> [Enterprise Configuration](../cli/enterprise.md) documentation.
+
+### 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.
+    - **`disableFuzzySearch`** (boolean): When `true`, disables the fuzzy search
+      capabilities when searching for files, which can improve performance on
+      projects with a large number of files.
+  - **Example:**
+    ```json
+    "fileFiltering": {
+      "respectGitIgnore": true,
+      "enableRecursiveFileSearch": false,
+      "disableFuzzySearch": true
+    }
+    ```
+
+### Troubleshooting file search performance
+
+If you are experiencing performance issues with file searching (e.g., with `@`
+completions), especially in projects with a very large number of files, here are
+a few things you can try in order of recommendation:
+
+1.  **Use `.geminiignore`:** Create a `.geminiignore` file in your project root
+    to exclude directories that contain a large number of files that you don't
+    need to reference (e.g., build artifacts, logs, `node_modules`). Reducing
+    the total number of files crawled is the most effective way to improve
+    performance.
+
+2.  **Disable fuzzy search:** If ignoring files is not enough, you can disable
+    fuzzy search by setting `disableFuzzySearch` to `true` in your
+    `settings.json` file. This will use a simpler, non-fuzzy matching algorithm,
+    which can be faster.
+
+3.  **Disable recursive file search:** As a last resort, you can disable
+    recursive file search entirely by setting `enableRecursiveFileSearch` to
+    `false`. This will be the fastest option as it avoids a recursive crawl of
+    your project. However, it means you will need to type the full path to files
+    when using `@` completions.
+
+- **`coreTools`** (array of strings):
+  - **Description:** Allows you to specify a list of core tool names that should
+    be made available to the model. This can be used to restrict the set of
+    built-in tools. See [Built-in Tools](../core/tools-api.md#built-in-tools)
+    for a list of core tools. You can also specify command-specific restrictions
+    for tools that support it, like the `ShellTool`. For example,
+    `"coreTools": ["ShellTool(ls -l)"]` will only allow the `ls -l` command to
+    be executed.
+  - **Default:** All tools available for use by the Gemini model.
+  - **Example:** `"coreTools": ["ReadFileTool", "GlobTool", "ShellTool(ls)"]`.
+
+- **`allowedTools`** (array of strings) [DEPRECATED]:
+  - **Default:** `undefined`
+  - **Description:** A list of tool names that will bypass the confirmation
+    dialog. This is useful for tools that you trust and use frequently. The
+    match semantics are the same as `coreTools`. **Deprecated**: Use the
+    [Policy Engine](../core/policy-engine.md) instead.
+  - **Example:** `"allowedTools": ["ShellTool(git status)"]`.
+
+- **`excludeTools`** (array of strings) [DEPRECATED]:
+  - **Description:** Allows you to specify a list of core tool names that should
+    be excluded from the model. A tool listed in both `excludeTools` and
+    `coreTools` is excluded. You can also specify command-specific restrictions
+    for tools that support it, like the `ShellTool`. For example,
+    `"excludeTools": ["ShellTool(rm -rf)"]` will block the `rm -rf` command.
+    **Deprecated**: Use the [Policy Engine](../core/policy-engine.md) instead.
+  - **Default**: No tools excluded.
+  - **Example:** `"excludeTools": ["run_shell_command", "findFiles"]`.
+  - **Security Note:** Command-specific restrictions in `excludeTools` for
+    `run_shell_command` are based on simple string matching and can be easily
+    bypassed. This feature is **not a security mechanism** and should not be
+    relied upon to safely execute untrusted code. It is recommended to use
+    `coreTools` to explicitly select commands that can be executed.
+
+- **`allowMCPServers`** (array of strings):
+  - **Description:** Allows you to specify a list of MCP server names that
+    should be made available to the model. This can be used to restrict the set
+    of MCP servers to connect to. Note that this will be ignored if
+    `--allowed-mcp-server-names` is set.
+  - **Default:** All MCP servers are available for use by the Gemini model.
+  - **Example:** `"allowMCPServers": ["myPythonServer"]`.
+  - **Security note:** This uses simple string matching on MCP server names,
+    which can be modified. If you're a system administrator looking to prevent
+    users from bypassing this, consider configuring the `mcpServers` at the
+    system settings level such that the user will not be able to configure any
+    MCP servers of their own. This should not be used as an airtight security
+    mechanism.
+
+- **`excludeMCPServers`** (array of strings):
+  - **Description:** Allows you to specify a list of MCP server names that
+    should be excluded from the model. A server listed in both
+    `excludeMCPServers` and `allowMCPServers` is excluded. Note that this will
+    be ignored if `--allowed-mcp-server-names` is set.
+  - **Default**: No MCP servers excluded.
+  - **Example:** `"excludeMCPServers": ["myNodeServer"]`.
+  - **Security note:** This uses simple string matching on MCP server names,
+    which can be modified. If you're a system administrator looking to prevent
+    users from bypassing this, consider configuring the `mcpServers` at the
+    system settings level such that the user will not be able to configure any
+    MCP servers of their own. This should not be used as an airtight security
+    mechanism.
+
+- **`theme`** (string):
+  - **Description:** Sets the visual [theme](../cli/themes.md) for Gemini CLI.
+  - **Default:** `"Default"`
+  - **Example:** `"theme": "GitHub"`
+
+- **`vimMode`** (boolean):
+  - **Description:** Enables or disables vim mode for input editing. When
+    enabled, the input area supports vim-style navigation and editing commands
+    with NORMAL and INSERT modes. The vim mode status is displayed in the footer
+    and persists between sessions.
+  - **Default:** `false`
+  - **Example:** `"vimMode": true`
+
+- **`sandbox`** (boolean or string):
+  - **Description:** Controls whether and how to use sandboxing for tool
+    execution. If set to `true`, Gemini CLI uses a pre-built
+    `gemini-cli-sandbox` Docker image. For more information, see
+    [Sandboxing](#sandboxing).
+  - **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. At least one of `command`, `url`, or
+    `httpUrl` must be provided. If multiple are specified, the order of
+    precedence is `httpUrl`, then `url`, then `command`.
+  - **Default:** Empty
+  - **Properties:**
+    - **`<SERVER_NAME>`** (object): The server parameters for the named server.
+      - `command` (string, optional): The command to execute to start the MCP
+        server via standard I/O.
+      - `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.
+      - `url` (string, optional): The URL of an MCP server that uses Server-Sent
+        Events (SSE) for communication.
+      - `httpUrl` (string, optional): The URL of an MCP server that uses
+        streamable HTTP for communication.
+      - `headers` (object, optional): A map of HTTP headers to send with
+        requests to `url` or `httpUrl`.
+      - `timeout` (number, optional): Timeout in milliseconds for requests to
+        this MCP server.
+      - `trust` (boolean, optional): Trust this server and bypass all tool call
+        confirmations.
+      - `description` (string, optional): A brief description of the server,
+        which may be used for display purposes.
+      - `includeTools` (array of strings, optional): List of tool names to
+        include from this MCP server. When specified, only the tools listed here
+        will be available from this server (allowlist behavior). If not
+        specified, all tools from the server are enabled by default.
+      - `excludeTools` (array of strings, optional): List of tool names to
+        exclude from this MCP server. Tools listed here will not be available to
+        the model, even if they are exposed by the server. **Note:**
+        `excludeTools` takes precedence over `includeTools` - if a tool is in
+        both lists, it will be excluded.
+  - **Example:**
+    ```json
+    "mcpServers": {

+
+## 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 and `.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. For authentication setup, see the
+[Authentication documentation](./authentication.md) which covers all available
+authentication methods.
+
+The CLI automatically loads environment variables from an `.env` file. The
+loading order is:
+
+1.  `.env` file in the current working directory.
+2.  If not found, it searches upwards in parent directories until it finds an
+    `.env` file or reaches the project root (identified by a `.git` folder) or
+    the home directory.
+3.  If still not found, it looks for `~/.env` (in the user's home directory).
+
+**Environment variable exclusion:** Some environment variables (like `DEBUG` and
+`DEBUG_MODE`) are automatically excluded from being loaded from project `.env`
+files to prevent interference with gemini-cli behavior. Variables from
+`.gemini/.env` files are never excluded. You can customize this behavior using
+the `excludedProjectEnvVars` setting in your `settings.json` file.
+
+- **`GEMINI_API_KEY`**:
+  - Your API key for the Gemini API.
+  - One of several available [authentication methods](./authentication.md).
+  - Set this in your shell profile (e.g., `~/.bashrc`, `~/.zshrc`) or an `.env`
+    file.
+- **`GEMINI_MODEL`**:
+  - Specifies the default Gemini model to use.
+  - Overrides the hardcoded default
+  - Example: `export GEMINI_MODEL="gemini-2.5-flash"`
+- **`GOOGLE_API_KEY`**:
+  - Your Google Cloud API key.
+  - Required for using Vertex AI in express mode.
+  - Ensure you have the necessary permissions.
+  - Example: `export GOOGLE_API_KEY="YOUR_GOOGLE_API_KEY"`.
+- **`GOOGLE_CLOUD_PROJECT`**:
+  - Your Google Cloud Project ID.
+  - Required for using Code Assist or Vertex AI.
+  - If using Vertex AI, ensure you have the necessary permissions in this
+    project.
+  - **Cloud Shell note:** When running in a Cloud Shell environment, this
+    variable defaults to a special project allocated for Cloud Shell users. If
+    you have `GOOGLE_CLOUD_PROJECT` set in your global environment in Cloud
+    Shell, it will be overridden by this default. To use a different project in
+    Cloud Shell, you must define `GOOGLE_CLOUD_PROJECT` in a `.env` file.
+  - Example: `export GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"`.
+- **`GOOGLE_APPLICATION_CREDENTIALS`** (string):
+  - **Description:** The path to your Google Application Credentials JSON file.
+  - **Example:**
+    `export GOOGLE_APPLICATION_CREDENTIALS="/path/to/your/credentials.json"`
+- **`OTLP_GOOGLE_CLOUD_PROJECT`**:
+  - Your Google Cloud Project ID for Telemetry in Google Cloud
+  - Example: `export OTLP_GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"`.
+- **`GOOGLE_CLOUD_LOCATION`**:
+  - Your Google Cloud Project Location (e.g., us-central1).
+  - Required for using Vertex AI in non express mode.
+  - Example: `export GOOGLE_CLOUD_LOCATION="YOUR_PROJECT_LOCATION"`.
+- **`GEMINI_SANDBOX`**:
+  - Alternative to the `sandbox` setting in `settings.json`.
+  - Accepts `true`, `false`, `docker`, `podman`, or a custom command string.
+- **`HTTP_PROXY` / `HTTPS_PROXY`**:
+  - Specifies the proxy server to use for outgoing HTTP/HTTPS requests.
+  - Example: `export HTTPS_PROXY="http://proxy.example.com:8080"`
+- **`SEATBELT_PROFILE`** (macOS specific):
+  - Switches the Seatbelt (`sandbox-exec`) profile on macOS.
+  - `permissive-open`: (Default) Restricts writes to the project folder (and a
+    few other folders, see
+    `packages/cli/src/utils/sandbox-macos-permissive-open.sb`) but allows other
+    operations.
+  - `strict`: Uses a strict profile that declines operations by default.
+  - `<profile_name>`: Uses a custom profile. To define a custom profile, create
+    a file named `sandbox-macos-<profile_name>.sb` in your project's `.gemini/`
+    directory (e.g., `my-project/.gemini/sandbox-macos-custom.sb`).
+- **`DEBUG` or `DEBUG_MODE`** (often used by underlying libraries or the CLI
+  itself):
+  - Set to `true` or `1` to enable verbose debug logging, which can be helpful
+    for troubleshooting.
+  - **Note:** These variables are automatically excluded from project `.env`
+    files by default to prevent interference with gemini-cli behavior. Use
+    `.gemini/.env` files if you need to set these for gemini-cli specifically.
+- **`NO_COLOR`**:
+  - Set to any value to disable all color output in the CLI.
+- **`CLI_TITLE`**:
+  - Set to a string to customize the title of the CLI.
+- **`CODE_ASSIST_ENDPOINT`**:
+  - Specifies the endpoint for the code assist server.
+  - This is useful for development and testing.
+
+## 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.
+- **`--prompt-interactive <your_prompt>`** (**`-i <your_prompt>`**):
+  - Starts an interactive session with the provided prompt as the initial input.
+  - The prompt is processed within the interactive session, not before it.
+  - Cannot be used when piping input from stdin.
+  - Example: `gemini -i "explain this code"`
+- **`--sandbox`** (**`-s`**):
+  - Enables sandbox mode for this session.
+- **`--sandbox-image`**:
+  - Sets the sandbox image URI.
+- **`--debug`** (**`-d`**):
+  - Enables debug mode for this session, providing more verbose output.
+
+- **`--help`** (or **`-h`**):
+  - Displays help information about command-line arguments.
+- **`--show-memory-usage`**:
+  - Displays the current memory usage.

+    - `auto_edit`: Automatically approve edit tools (replace, write_file) while
+      prompting for others
+    - `yolo`: Automatically approve all tool calls (equivalent to `--yolo`)
+  - Cannot be used together with `--yolo`. Use `--approval-mode=yolo` instead of
+    `--yolo` for the new unified approach.
+  - Example: `gemini --approval-mode auto_edit`
+- **`--allowed-tools <tool1,tool2,...>`**:
+  - A comma-separated list of tool names that will bypass the confirmation
+    dialog.
+  - Example: `gemini --allowed-tools "ShellTool(git status)"`
+- **`--telemetry`**:
+  - Enables [telemetry](../cli/telemetry.md).

+  - Example: `gemini -e my-extension -e my-other-extension`
+- **`--list-extensions`** (**`-l`**):
+  - Lists all available extensions and exits.
+- **`--include-directories <dir1,dir2,...>`**:
+  - Includes additional directories in the workspace for multi-directory
+    support.
+  - Can be specified multiple times or as comma-separated values.
+  - 5 directories can be added at maximum.
+  - Example: `--include-directories /path/to/project1,/path/to/project2` or
+    `--include-directories /path/to/project1 --include-directories /path/to/project2`
+- **`--screen-reader`**:
+  - Enables screen reader mode for accessibility.
+- **`--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 20+.
+
+## Coding Style:
+
+- Use 2 spaces for indentation.
+- Interface names should be prefixed with `I` (e.g., `IUserService`).
+- Private class members should be prefixed with an underscore (`_`).
+- Always use strict equality (`===` and `!==`).
+
+## Specific Component: `src/api/client.ts`
+
+- This file handles all outbound API requests.
+- When adding new API call functions, ensure they include robust error handling
+  and logging.
+- Use the existing `fetchWithRetry` utility for all GET requests.
+
+## Regarding Dependencies:
+
+- Avoid introducing new external dependencies unless absolutely necessary.
+- If a new dependency is required, please state the reason.
+```
+
+This example demonstrates how you can provide general project context, specific
+coding conventions, and even notes about particular files or components. The
+more relevant and precise your context files are, the better the AI can assist
+you. Project-specific context files are highly encouraged to establish
+conventions and context.
+
+- **Hierarchical loading and precedence:** The CLI implements a sophisticated
+  hierarchical memory system by loading context files (e.g., `GEMINI.md`) from
+  several locations. Content from files lower in this list (more specific)
+  typically overrides or supplements content from files higher up (more
+  general). The exact concatenation order and final context can be inspected
+  using the `/memory show` command. The typical loading order is:
+  1.  **Global context file:**
+      - Location: `~/.gemini/<contextFileName>` (e.g., `~/.gemini/GEMINI.md` in
+        your user home directory).
+      - Scope: Provides default instructions for all your projects.
+  2.  **Project root and ancestors context files:**
+      - Location: The CLI searches for the configured context file in the
+        current working directory and then in each parent directory up to either
+        the project root (identified by a `.git` folder) or your home directory.
+      - Scope: Provides context relevant to the entire project or a significant
+        portion of it.
+  3.  **Sub-directory context files (contextual/local):**
+      - Location: The CLI also scans for the configured context file in
+        subdirectories _below_ the current working directory (respecting common
+        ignore patterns like `node_modules`, `.git`, etc.). The breadth of this
+        search is limited to 200 directories by default, but can be configured
+        with a `memoryDiscoveryMaxDirs` field in your `settings.json` file.
+      - Scope: Allows for highly specific instructions relevant to a particular
+        component, module, or subsection of your project.
+- **Concatenation and UI indication:** The contents of all found context files
+  are concatenated (with separators indicating their origin and path) and
+  provided as part of the system prompt to the Gemini model. The CLI footer
+  displays the count of loaded context files, giving you a quick visual cue
+  about the active instructional context.
+- **Importing content:** You can modularize your context files by importing
+  other Markdown files using the `@path/to/file.md` syntax. For more details,
+  see the [Memory Import Processor documentation](../core/memport.md).
+- **Commands for memory management:**
+  - Use `/memory refresh` to force a re-scan and reload of all context files
+    from all configured locations. This updates the AI's instructional context.
+  - Use `/memory show` to display the combined instructional context currently
+    loaded, allowing you to verify the hierarchy and content being used by the
+    AI.
+  - See the [Commands documentation](../cli/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 when using `--yolo` or `--approval-mode=yolo` 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
+}
