+prompt = """
+Please provide a detailed pull request review on GitHub issue: {{args}}.
+
+Follow these steps:
+
+1. Use `gh pr view {{args}}` to pull the information of the PR.
+2. Use `gh pr diff {{args}}` to view the diff of the PR.
+3. Understand the intent of the PR using the PR description.
+4. If PR description is not detailed enough to understand the intent of the PR,
+   make sure to note it in your review.
+5. Make sure the PR title follows Conventional Commits, here are the last five
+   commits to the repo as examples: !{git log --pretty=format:"%s" -n 5}
+6. Search the codebase if required.
+7. Write a concise review of the PR, keeping in mind to encourage strong code
+   quality and best practices. Pay particular attention to the Gemini MD file
+   in the repo.
+8. Consider ways the code may not be consistent with existing code in the repo.
+   In particular it is critical that the react code uses patterns consistent
+   with existing code in the repo.
+9. Evaluate all tests on the PR and make sure that they are doing the following:
+   * Using `waitFor` from @{packages/cli/src/test-utils/async.ts} rather than
+     using `vi.waitFor` for all `waitFor` calls within `packages/cli`. Even if
+     tests pass, using the wrong `waitFor` could result in flaky tests as `act`
+     warnings could show up if timing is slightly different.
+   * Using `act` to wrap all blocks in tests that change component state.
+   * Using `toMatchSnapshot` to verify that rendering works as expected rather
+     than matching against the raw content of the output.
+   * If snapshots were changed as part of the pull request, review the snapshots
+     changes to ensure they are intentional and comment if any look at all
+     suspicious. Too many snapshot changes that indicate bugs have been approved
+     in the past.
+   * Use `render` or `renderWithProviders` from
+     @{packages/cli/src/test-utils/render.tsx} rather than using `render` from
+     `ink-testing-library` directly. This is needed to ensure that we do not get
+     warnings about spurious `act` calls. If test cases specify providers
+     directly, consider whether the existing `renderWithProviders` should be
+     modified to support that use case.
+   * Ensure the test cases are using parameterized tests where that might reduce
+     the number of duplicated lines significantly.
+   * NEVER use fixed waits (e.g. 'await delay(100)'). Always use 'waitFor' with
+     a predicate to ensure tests are stable and fast.
+   * Ensure mocks are properly managed:
+     * Critical dependencies (fs, os, child_process) should only be mocked at
+       the top of the file. Ideally avoid mocking these dependencies altogether.
+     * Check to see if there are existing mocks or fakes that can be used rather
+       than creating new ones for the new tests added.
+     * Try to avoid mocking the file system whenever possible. If using the real
+       file system is difficult consider whether the test should be an
+       integration test rather than a unit test.
+     * `vi.restoreAllMocks()` should be called in `afterEach` to prevent test
+       pollution.
+     * Use `vi.useFakeTimers()` for tests involving time-based logic to avoid
+       flakiness.
+     * Avoid using `any` in tests; prefer proper types or `unknown` with
+       narrowing.
+     * When creating parameterized tests, give the parameters types to ensure
+       that the tests are type-safe.
+10. Evaluate all react logic carefully keeping in mind that the author of the PR
+    is not likely an expert on React. Key areas to audit carefully are:
+    * Whether `setState` calls trigger side effects from within the body of the
+      `setState` callback. If so, you *must* propose an alternate design using
+      reducers or other ways the code might be modified to not have to modify
+      state from within a `setState`. Make sure to comment about absolutely
+      every case like this as these cases have introduced multiple bugs in the
+      past. Typically these cases should be resolved using a reducer although
+      occassionally other techniques such as useRef are appropriate. Consider
+      suggesting that jacob314@ be tagged on the code review if the solution is
+      not 100% obvious.
+    * Whether code might introduce an infinite rendering loop in React.
+    * Whether keyboard handling is robust. Keyboard handling must go through
+      `useKeyPress.ts` from the Gemini CLI package rather than using the
+      standard ink library used by most keyboard handling. Unlike the standard
+      ink library, the keyboard handling library in Gemini CLI may report
+      multiple keyboard events one after another in the same React frame. This
+      is needed to support slow terminals but introduces complexity in all our
+      code that handles keyboard events. Handling this correctly often means
+      that reducers must be used or other mechanisms to ensure that multiple
+      state updates one after another are handled gracefully rather than
+      overriding values from the first update with the second update. Refer to
+      text-buffer.ts as a canonical example of using a reducer for this sort of
+      case.
+    * Ensure code does not use `console.log`, `console.warn`, or `console.error`
+      as these indicate debug logging that was accidentally left in the code.
+    * Avoid synchronous file I/O in React components as it will hang the UI.
+    * Ensure state initialization is explicit (e.g., use 'undefined' rather than
+      'true' as a default if the state is truly unknown initially).
+    * Carefully manage 'useEffect' dependencies. Prefer to use a reducer
+      whenever practical to resolve the issues. If that is not practical it is
+      ok to use 'useRef' to access the latest value of a prop or state inside an
+      effect without adding it to the dependency array if re-running the effect
+      is undesirable (common in event listeners).
+    * NEVER disable 'react-hooks/exhaustive-deps'. Fix the code to correctly
+      declare dependencies. Disabling this lint rule will almost always lead to
+      hard to detect bugs.
+    * Avoid making types nullable unless strictly necessary, as it hurts
+      readability.
+    * Do not introduce excessive property drilling. There are multiple providers
+      that can be leveraged to avoid property drilling. Make sure one of them
+      cannot be used. Do suggest a provider that might make sense to be extended
+      to include the new property or propose a new provider to add if the
+      property drilling is excessive. Only use providers for properties that are
+      consistent for the entire application.
+11. General Gemini CLI design principles:
+    * Make sure that settings are only used for options that a user might
+      consider changing.
+    * Do not add new command line arguments and suggest settings instead.
+    * New settings must be added to packages/cli/src/config/settingsSchema.ts.
+    * If a setting has 'showInDialog: true', it MUST be documented in
+      docs/get-started/configuration.md.
+    * Ensure 'requiresRestart' is correctly set for new settings.
+    * Use 'debugLogger' for rethrown errors to avoid duplicate logging.
+    * All new keyboard shortcuts MUST be documented in
+      docs/cli/keyboard-shortcuts.md.
+    * Ensure new keyboard shortcuts are defined in
+      packages/cli/src/config/keyBindings.ts.
+    * If new keyboard shortcuts are added, remind the user to test them in
+      VSCode, iTerm2, Ghostty, and Windows to ensure they work for all
+      users.
+    * Be careful of keybindings that require the meta key as only certain
+      meta key shortcuts are supported on Mac.
+    * Be skeptical of function keys and keyboard shortcuts that are commonly
+      bound in VSCode as they may conflict.
+12. TypeScript Best Practices:
+    * Use 'checkExhaustive' in the 'default' clause of 'switch' statements to
+      ensure all cases are handled.
+    * Avoid using the non-null assertion operator ('!') unless absolutely
+      necessary and you are confident the value is not null.
+13. If the change might at all impact the prompts sent to Gemini CLI, flagged
+    that the change could impact Gemini CLI quality and make sure anj-s has been
+    tagged on the code review.
+14. Discuss with me before making any comments on the issue. I will clarify
+    which possible issues you identified are problems, which ones you need to
+    investigate further, and which ones I do not care about.
+15. If I request you to add comments to the issue, use
+    `gh pr comment {{args}} --body {{review}}` to post the review to the PR.
+
+Remember to use the GitHub CLI (`gh`) with the Shell tool for all
+GitHub-related tasks.

             ## Role
 
-            You are an issue triage assistant. Analyze the current GitHub issue
-            and identify the most appropriate existing labels by only using the provided data. Use the available
-            tools to gather information; do not ask for information to be
-            provided. Do not remove the following labels titled maintainer,  help wanted or good first issue.
+            You are an issue triage assistant. Your role is to analyze a GitHub issue and determine the single most appropriate area/ label and the single most appropriate priority/ label based on the definitions provided.
 
             ## Steps
-
-            1. You are only able to use the echo command. Review the available labels in the environment variable: "${AVAILABLE_LABELS}".
-            2. Review the issue title and body provided in the environment variables: "${ISSUE_TITLE}" and "${ISSUE_BODY}".
-            3. Select the most relevant labels from the existing labels, focusing on kind/*, area/*, sub-area/* and priority/*. For area/* and kind/* limit yourself to only the single most applicable label in each case.
-            4. If the issue already has area/ label, dont try to change it. Similarly, if the issue already has a kind/ label don't change it. And if the issue already has a priority/ label do not change it for example:
-               If an issue has area/core and kind/bug  you will only add a priority/ label.
-               Instead if an issue has no labels, you will could add one lable of each kind.
-            5. For each issue please check if CLI version is present, this is usually in the output of the /about command and will look like 0.1.5 for anything more than 6 versions older than the most recent should add the status/need-retesting label.
-            6. If you see that the issue doesn't look like it has sufficient information recommend the status/need-information label and leave a comment politely requesting the relevant information, eg.. if repro steps are missing request for repro steps. if version information is missing request for version information into the explanation section below.
-            7. Output the appropriate labels for this issue in JSON format with explanation, for example:
-               ```
-               {"labels_to_set": ["kind/bug", "priority/p0"], "explanation": "This is a critical bug report affecting main functionality"}
-               ```
-            8. If the issue cannot be classified using the available labels, output:
-               ```
-               {"labels_to_set": [], "explanation": "Unable to classify this issue with available labels"}
-               ```
-            9. Use Area definitions mentioned below to help you narrow down issues.
-            10. If you think an issue might be a Priority/P0 do not apply the priority/p0 label. Instead apply a status/manual-triage label and include a note in your explanation.
-            11. If you are uncertain and have not been able to apply one each of kind/, area/ and priority/ , apply the status/manual-triage label.
+            1. Review the issue title and body: ${{ env.ISSUE_TITLE }} and ${{ env.ISSUE_BODY }}.
+            2. Review the available labels: ${{ env.AVAILABLE_LABELS }}.
+            3. Select exactly one area/ label that best matches the issue based on Reference 1: Area Definitions.
+            4. Select exactly one priority/ label that best matches the issue based on Reference 2: Priority Definitions.
+            5. Fallback Logic:
+                - If you cannot confidently determine the correct area/ label from the definitions, you must use area/unknown.
+                - If you cannot confidently determine the correct priority/ label from the definitions, you must use priority/unknown.
+            6. Output your two selected labels in JSON format and nothing else. Example:
+                {"labels_to_set": ["area/core", "priority/p1"]}
 
             ## Guidelines
+            - Your output must contain exactly one area/ label and exactly one priority/ label.
+            - Triage only the current issue based on its title and body.
+            - Output only valid JSON format.
+            - Do not include any explanation or additional text, just the JSON.
 
-            - Only use labels that already exist in the repository
-            - Do not add comments or modify the issue content
-            - Triage only the current issue
-            - Identify only one area/ label
-            - Identify only one kind/ label
-            - Identify all applicable sub-area/* and priority/* labels based on the issue content. It's ok to have multiple of these
-            - Once you categorize the issue if it needs information bump down the priority by 1 eg.. a p0 would become a p1 a p1 would become a p2. P2 and P3 can stay as is in this scenario
-            - Reference all shell variables as "${VAR}" (with quotes and braces)
-            - Output only valid JSON format
-            - Do not include any explanation or additional text, just the JSON

+            area/agent
+            - Description: Issues related to the "brain" of the CLI. This includes the core agent logic, model quality, tool/function calling, and memory.

+              "The generated code is poor quality or incorrect."
+              "The model seems stuck in a loop."
+              "The response from the model is malformed (e.g., broken JSON, bad formatting)."
+              "Concerns about unnecessary token consumption."
+              "Issues with how memory or chat history is managed."
+              "Issues with sub-agents."
+              "Model is switching from one to another unexpectedly."
 
-            Categorization Guidelines:
-            P0: Critical / Blocker
-            - A P0 bug is a catastrophic failure that demands immediate attention.
-            - To be a P0 it means almost all users are running into this issue and it is blocking users from being able to use the product.
-            - You would see this in the form of many comments from different developers on the bug.
-            - It represents a complete showstopper for a significant portion of users or for the development process itself.
-            Impact:
-            - Blocks development or testing for the entire team.
-            - Major security vulnerability that could compromise user data or system integrity.
-            - Causes data loss or corruption with no workaround.
-            - Crashes the application or makes a core feature completely unusable for all or most users in a production environment. Will it cause severe quality degration? Is it preventing contributors from contributing to the repository or is it a release blocker?
-            Qualifier: Is the main function of the software broken?
-            Example: The gemini auth login command fails with an unrecoverable error, preventing any user from authenticating and using the rest of the CLI.
-            P1: High
-            - A P1 bug is a serious issue that significantly degrades the user experience or impacts a core feature.
-            - While not a complete blocker, it's a major problem that needs a fast resolution. Feature requests are almost never P1.
-            - Once again this would be affecting many users.
-            - You would see this in the form of comments from different developers on the bug.
-            Impact:
-            - A core feature is broken or behaving incorrectly for a large number of users or large number of use cases.
-            - Review the bug details and comments to try figure out if this issue affects a large set of use cases or if it's a narrow set of use cases.
-            - Severe performance degradation making the application frustratingly slow.
-            - No straightforward workaround exists, or the workaround is difficult and non-obvious.
-            Qualifier: Is a key feature unusable or giving very wrong results?
-            Example: Gemini CLI enters a loop when making read-many-files tool call. I am unable to break out of the loop and gemini doesn't follow instructions subsequently.
-            P2: Medium
-            - A P2 bug is a moderately impactful issue. It's a noticeable problem but doesn't prevent the use of the software's main functionality.
-            Impact:
-            - Affects a non-critical feature or a smaller, specific subset of users.
-            - An inconvenient but functional workaround is available and easy to execute.
-            - Noticeable UI/UX problems that don't break functionality but look unprofessional (e.g., elements are misaligned or overlapping).
-            Qualifier: Is it an annoying but non-blocking problem?
-            Example: An error message is unclear or contains a typo, causing user confusion but not halting their workflow.
-            P3: Low
-            - A P3 bug is a minor, low-impact issue that is trivial or cosmetic. It has little to no effect on the overall functionality of the application.
-            Impact:
-            - Minor cosmetic issues like color inconsistencies, typos in documentation, or slight alignment problems on a non-critical page.
-            - An edge-case bug that is very difficult to reproduce and affects a tiny fraction of users.
-            Qualifier: Is it a "nice-to-fix" issue?
-            Example: Spelling mistakes etc.
-            Things you should know:
-            - If users are talking about issues where the model gets downgraded from pro to flash then i want you to categorize that as a performance issue
-            - This product is designed to use different models eg.. using pro, downgrading to flash etc. when users report that they dont expect the model to change those would be categorized as feature requests.

+
+            Reference 2: Priority Definitions
+            priority/p0: Critical / Blocker
+            - Definition: A catastrophic failure that makes the CLI unusable for most users or poses a severe security risk. This includes installation failures, authentication failures, persistent crashes, or critical security vulnerabilities.
+            - Key Questions:
+              - Is the CLI failing to install or run?
+              - Does it fail to authenticate or connect to the Gemini API, making all commands useless?
+              - Is it consistently crashing on basic, common commands?
+              - Does this represent a critical security vulnerability?
+
+            priority/p1: High
+            - Definition: A severe issue where a core feature (e.g., text generation, code generation, file processing) is unusable, failing, has severe performance degradation, or providing fundamentally incorrect output formatting (e.g., truncated text, broken JSON). Affects many users, and there is no reasonable workaround.
+            - Key Questions:
+              - Is a core feature failing for a specific, large user group (e.g., all Windows users, all users of a specific shell)?
+              - Is the CLI failing to process a supported input or misinterpreting critical flags?
+              - Is the CLI's output formatting consistently broken, making the response unusable?
+              - Is a core command or feature extremely slow, making it impractical to use?
+
+            priority/p2: Medium
+            - Definition: A moderately impactful issue causing inconvenience or a non-optimal experience, but a reasonable workaround exists. This also includes failures in non-core features.
+            - Key Questions:
+              - Is a command or flag behaving incorrectly, but the user can achieve their goal via other means?
+              - Is there a significant, non-blocking UI/UX problem in the terminal (e.g., broken progress indicators, bad terminal coloring)?
+
+            priority/p3: Low
+            - Definition: A minor, low-impact issue with minimal effect on functionality. This includes most cosmetic defects, typos in documentation, or unclear help text.
+            - Key Questions:
+              - Is this a typo in the README.md, gemini --help text, or other documentation?
+              - Is this a minor cosmetic issue (e.g., text alignment in output, an extra newline) that doesn't affect usability?
+
+            priority/unknown
+            - Description: Issues that do not clearly fit into any other defined priority/ category, or where information is too limited to make a determination. Use this when no other priority is appropriate.

+## Model Routing
+
+Gemini CLI includes a model routing feature that automatically switches to a
+fallback model in case of a model failure. This feature is enabled by default
+and provides resilience when the primary model is unavailable.
+
+## How it Works
+
+Model routing is not based on prompt complexity, but is a fallback mechanism.
+Here's how it works:
+
+1.  **Model Failure:** If the currently selected model fails to respond (for
+    example, due to a server error or other issue), the CLI will initiate the
+    fallback process.
+
+2.  **User Consent:** The CLI will prompt you to ask if you want to switch to
+    the fallback model. This is handled by the `fallbackModelHandler`.
+
+3.  **Fallback Activation:** If you consent, the CLI will activate the fallback
+    mode by calling `config.setFallbackMode(true)`.
+
+4.  **Model Switch:** On the next request, the CLI will use the
+    `DEFAULT_GEMINI_FLASH_MODEL` as the fallback model. This is handled by the
+    `resolveModel` function in
+    `packages/cli/src/zed-integration/zedIntegration.ts` which checks if
+    `isInFallbackMode()` is true.
+
+## Configuration
+
+Model routing is controlled by the `useModelRouter` setting in your
+`settings.json` file.
+
+- **`"experimental.useModelRouter": true` (Default):** Enables the model
+  routing/fallback feature.
+
+- **`"experimental.useModelRouter": false`:** Disables the model
+  routing/fallback feature. If a model fails, the CLI will not attempt to switch
+  to a fallback model.
+
+### Model Selection Precedence
+
+The model used by Gemini CLI is determined by the following order of precedence:
+
+1.  **`--model` command-line flag:** A model specified with the `--model` flag
+    when launching the CLI will always be used.
+2.  **`GEMINI_MODEL` environment variable:** If the `--model` flag is not used,
+    the CLI will use the model specified in the `GEMINI_MODEL` environment
+    variable.
+3.  **`model.name` in `settings.json`:** If neither of the above are set, the
+    model specified in the `model.name` property of your `settings.json` file
+    will be used.
+4.  **Default Model:** If none of the above are set, the default model will be
+    used. The default model is determined by the `useModelRouter` setting:
+    - If `useModelRouter` is `true`, the default model is `"auto"`.
+    - If `useModelRouter` is `false`, the default model is the standard Gemini
+      model.

+Select your Gemini CLI model. The `/model` command opens a dialog where you can
+configure the model used by Gemini CLI, giving you more control over your
+results.
+
+## How to use the `/model` command
+
+Use the following command in Gemini CLI:
+
+```
+/model
+```
+
+Running this command will open a dialog with your model options:
+
+| Option             | Description                                                   | Models                                                                                     |
+| ------------------ | ------------------------------------------------------------- | ------------------------------------------------------------------------------------------ |
+| Auto (recommended) | Let the system choose the best model for your task.           | gemini-3-pro-preview (if enabled), gemini-2.5-pro, gemini-2.5-flash, gemini-2.5-flash-lite |
+| Pro                | For complex tasks that require deep reasoning and creativity. | gemini-3-pro-preview (if enabled), gemini-2.5-pro                                          |
+| Flash              | For tasks that need a balance of speed and reasoning.         | gemini-2.5-flash                                                                           |
+| Flash-Lite         | For simple tasks that need to be done quickly.                | gemini-2.5-flash-lite                                                                      |

+### Gemini 3 Pro and Preview Features
+
+Note: Gemini 3 is not currently available on all account types. To learn more
+about Gemini 3 access, refer to
+[Gemini 3 Pro on Gemini CLI](../get-started/gemini-3.md).
+
+To enable Gemini 3 Pro (if available), enable
+[**Preview features** by using the `settings` command](../cli/settings.md). Once
+enabled, Gemini CLI will attempt to use Gemini 3 Pro when you select **Auto** or
+**Pro**. Both **Auto** and **Pro** will try to use Gemini 3 Pro before falling
+back to Gemini 2.5 Pro.
+
+You can also use the `--model` flag to specify a particular Gemini model on
+startup. For more details, refer to the
+[configuration documentation](./configuration.md).
+
+Changes to these settings will be applied to all subsequent interactions with
+Gemini CLI.
+
+## Best practices for model selection
+
+- **Default to Auto (recommended).** For most users, the _Auto (recommended)_
+  model provides a balance between speed and performance, automatically
+  selecting the correct model based on the complexity of the task. Example:
+  Developing a web application could include a mix of complex tasks (building
+  architecture and scaffolding the project) and simple tasks (generating CSS).
+
+- **Switch to Pro if you aren't getting the results you want.** If you think you
+  need your model to be a little "smarter," use Pro. Pro will provide you with
+  the highest levels of reasoning and creativity. Example: A complex or
+  multi-stage debugging task.
+
+- **Switch to Flash or Flash-Lite if you need faster results.** If you need a
+  simple response quickly, Flash or Flash-Lite is the best option. Example:
+  Converting a JSON object to a YAML string.

+# Gemini CLI Settings (`/settings` Command)
+
+Control your Gemini CLI experience with the `/settings` command. The `/settings`
+command opens a dialog to view and edit all your Gemini CLI settings, including
+your UI experience, keybindings, and accessibility features.
+
+Your Gemini CLI settings are stored in a `settings.json` file. In addition to
+using the `/settings` command, you can also edit them in one of the following
+locations:
+
+- **User settings**: `~/.gemini/settings.json`
+- **Workspace settings**: `your-project/.gemini/settings.json`
+
+Note: Workspace settings override user settings.
+

+# Policy Engine
+
+:::note This feature is currently in testing. To enable it, set
+`tools.enableMessageBusIntegration` to `true` in your `settings.json` file. :::
+
+The Gemini CLI includes a powerful policy engine that provides fine-grained
+control over tool execution. It allows users and administrators to define rules
+that determine whether a tool call should be allowed, denied, or require user
+confirmation.
+
+## Core concepts
+
+The policy engine operates on a set of rules. Each rule is a combination of
+conditions and a resulting decision. When a large language model wants to
+execute a tool, the policy engine evaluates all rules to find the
+highest-priority rule that matches the tool call.
+
+A rule consists of the following main components:
+
+- **Conditions**: Criteria that a tool call must meet for the rule to apply.
+  This can include the tool's name, the arguments provided to it, or the current
+  approval mode.
+- **Decision**: The action to take if the rule matches (`allow`, `deny`, or
+  `ask_user`).
+- **Priority**: A number that determines the rule's precedence. Higher numbers
+  win.
+
+For example, this rule will ask for user confirmation before executing any `git`
+command.
+
+```toml
+[[rule]]
+toolName = "run_shell_command"
+commandPrefix = "git "
+decision = "ask_user"
+priority = 100
+```
+
+### Conditions
+
+Conditions are the criteria that a tool call must meet for a rule to apply. The
+primary conditions are the tool's name and its arguments.
+
+#### Tool Name
+
+The `toolName` in the rule must match the name of the tool being called.
+
+- **Wildcards**: For Model-hosting-protocol (MCP) servers, you can use a
+  wildcard. A `toolName` of `my-server__*` will match any tool from the
+  `my-server` MCP.
+
+#### Arguments Pattern
+
+If `argsPattern` is specified, the tool's arguments are converted to a stable
+JSON string, which is then tested against the provided regular expression. If
+the arguments don't match the pattern, the rule does not apply.
+
+### Decisions
+
+There are three possible decisions a rule can enforce:
+
+- `allow`: The tool call is executed automatically without user interaction.
+- `deny`: The tool call is blocked and is not executed.
+- `ask_user`: The user is prompted to approve or deny the tool call. (In
+  non-interactive mode, this is treated as `deny`.)
+
+### Priority system & tiers
+
+The policy engine uses a sophisticated priority system to resolve conflicts when
+multiple rules match a single tool call. The core principle is simple: **the
+rule with the highest priority wins**.
+
+To provide a clear hierarchy, policies are organized into three tiers. Each tier
+has a designated number that forms the base of the final priority calculation.
+
+| Tier    | Base | Description                                                                |
+| :------ | :--- | :------------------------------------------------------------------------- |
+| Default | 1    | Built-in policies that ship with the Gemini CLI.                           |
+| User    | 2    | Custom policies defined by the user.                                       |
+| Admin   | 3    | Policies managed by an administrator (e.g., in an enterprise environment). |
+
+Within a TOML policy file, you assign a priority value from **0 to 999**. The
+engine transforms this into a final priority using the following formula:
+
+`final_priority = tier_base + (toml_priority / 1000)`
+
+This system guarantees that:
+
+- Admin policies always override User and Default policies.
+- User policies always override Default policies.
+- You can still order rules within a single tier with fine-grained control.
+
+For example:
+
+- A `priority: 50` rule in a Default policy file becomes `1.050`.
+- A `priority: 100` rule in a User policy file becomes `2.100`.
+- A `priority: 20` rule in an Admin policy file becomes `3.020`.
+
+### Approval modes
+
+Approval modes allow the policy engine to apply different sets of rules based on
+the CLI's operational mode. A rule can be associated with one or more modes
+(e.g., `yolo`, `autoEdit`). The rule will only be active if the CLI is running
+in one of its specified modes. If a rule has no modes specified, it is always
+active.
+
+## Rule matching
+
+When a tool call is made, the engine checks it against all active rules,
+starting from the highest priority. The first rule that matches determines the
+outcome.
+
+A rule matches a tool call if all of its conditions are met:
+
+1.  **Tool Name**: The `toolName` in the rule must match the name of the tool
+    being called.
+    - **Wildcards**: For Model-hosting-protocol (MCP) servers, you can use a
+      wildcard. A `toolName` of `my-server__*` will match any tool from the
+      `my-server` MCP.
+2.  **Arguments Pattern**: If `argsPattern` is specified, the tool's arguments
+    are converted to a stable JSON string, which is then tested against the
+    provided regular expression. If the arguments don't match the pattern, the
+    rule does not apply.
+
+## Configuration
+
+Policies are defined in `.toml` files. The CLI loads these files from Default,
+User, and (if configured) Admin directories.
+
+### TOML rule schema
+
+Here is a breakdown of the fields available in a TOML policy rule:
+
+```toml
+[[rule]]
+# A unique name for the tool, or an array of names.
+toolName = "run_shell_command"
+
+# (Optional) The name of an MCP server. Can be combined with toolName
+# to form a composite name like "mcpName__toolName".
+mcpName = "my-custom-server"
+
+# (Optional) A regex to match against the tool's arguments.
+argsPattern = '"command":"(git|npm)'
+
+# (Optional) A string or array of strings that a shell command must start with.
+# This is syntactic sugar for `toolName = "run_shell_command"` and an `argsPattern`.
+commandPrefix = "git "
+
+# (Optional) A regex to match against the entire shell command.
+# This is also syntactic sugar for `toolName = "run_shell_command"`.
+# Note: This pattern is tested against the JSON representation of the arguments (e.g., `{"command":"<your_command>"}`), so anchors like `^` or `$` will apply to the full JSON string, not just the command text.
+# You cannot use commandPrefix and commandRegex in the same rule.
+commandRegex = "^git (commit|push)"
+
+# The decision to take. Must be "allow", "deny", or "ask_user".
+decision = "ask_user"
+
+# The priority of the rule, from 0 to 999.
+priority = 10
+
+# (Optional) An array of approval modes where this rule is active.
+modes = ["autoEdit"]
+```
+
+### Using arrays (lists)
+
+To apply the same rule to multiple tools or command prefixes, you can provide an
+array of strings for the `toolName` and `commandPrefix` fields.
+
+**Example:**
+
+This single rule will apply to both the `write_file` and `replace` tools.
+
+```toml
+[[rule]]
+toolName = ["write_file", "replace"]
+decision = "ask_user"
+priority = 10
+```
+
+### Special syntax for `run_shell_command`
+
+To simplify writing policies for `run_shell_command`, you can use
+`commandPrefix` or `commandRegex` instead of the more complex `argsPattern`.
+
+- `commandPrefix`: Matches if the `command` argument starts with the given
+  string.
+- `commandRegex`: Matches if the `command` argument matches the given regular
+  expression.
+
+**Example:**
+
+This rule will ask for user confirmation before executing any `git` command.
+
+```toml
+[[rule]]
+toolName = "run_shell_command"
+commandPrefix = "git "
+decision = "ask_user"
+priority = 100
+```
+
+### Special syntax for MCP tools
+
+You can create rules that target tools from Model-hosting-protocol (MCP) servers
+using the `mcpName` field or a wildcard pattern.
+
+**1. Using `mcpName`**
+
+To target a specific tool from a specific server, combine `mcpName` and
+`toolName`.
+
+```toml
+# Allows the `search` tool on the `my-jira-server` MCP
+[[rule]]
+mcpName = "my-jira-server"
+toolName = "search"
+decision = "allow"
+priority = 200
+```
+
+**2. Using a Wildcard**
+
+To create a rule that applies to _all_ tools on a specific MCP server, specify
+only the `mcpName`.
+
+```toml
+# Denies all tools from the `untrusted-server` MCP
+[[rule]]
+mcpName = "untrusted-server"
+decision = "deny"
+priority = 500
+```
+
+## Default policies
+
+The Gemini CLI ships with a set of default policies to provide a safe
+out-of-the-box experience.
+
+- **Read-only tools** (like `read_file`, `glob`) are generally **allowed**.
+- **Write tools** (like `write_file`, `run_shell_command`) default to
+  **`ask_user`**.
+- In **`yolo`** mode, a high-priority rule allows all tools.
+- In **`autoEdit`** mode, rules allow certain write operations to happen without
+  prompting.

+# Gemini 3 Pro on Gemini CLI (Join the Waitlist)
+
+We’re excited to bring Gemini 3 Pro to Gemini CLI. For Google AI Ultra users
+(Google AI Ultra for Business is not currently supported) and paid Gemini and
+Vertex API key holders, Gemini 3 Pro is already available and ready to enable.
+For everyone else, we're gradually expanding access
+[through a waitlist](https://goo.gle/geminicli-waitlist-signup). Sign up for the
+waitlist now to access Gemini 3 Pro once approved.
+
+**Note:** Please wait until you have been approved to use Gemini 3 Pro to enable
+**Preview Features**. If enabled early, the CLI will fallback to Gemini 2.5 Pro.
+
+## Do I need to join the waitlist?
+
+The following users will be **automatically granted access** to Gemini 3 Pro on
+Gemini CLI:
+
+- Google AI Ultra subscribers (excluding Google AI Ultra for Business, which is
+  on the roadmap).
+- Gemini API key users
+  [with access to Gemini 3](https://ai.google.dev/gemini-api/docs/rate-limits).
+- Vertex API key users
+  [with access to Gemini 3](https://docs.cloud.google.com/vertex-ai/generative-ai/docs/quotas).
+
+For **Gemini Code Assist Enterprise users**, access is coming soon.
+
+Users not automatically granted access through one of these account types will
+need to join the waitlist. This includes Google AI Pro, Gemini Code Assist
+standard, and free tier users.
+
+Note: Whether you’re automatically granted access or accepted from the waitlist,
+you’ll still need to enable Gemini 3 Pro
+[using the `/settings` command](../cli/settings.md).
+
+## How to join the waitlist
+
+Users not automatically granted access will need to join the waitlist. Follow
+these instructions to sign up:
+
+- Install Gemini CLI.
+- Authenticate using the **Login with Google** option. You’ll see a banner that
+  says “Gemini 3 is now available.” If you do not see this banner, update your
+  installation of Gemini CLI to the most recent version.
+- Fill out this Google form:
+  [Access Gemini 3 in Gemini CLI](https://goo.gle/geminicli-waitlist-signup).
+  Provide the email address of the account you used to authenticate with Gemini
+  CLI.
+
+Users will be onboarded in batches, subject to availability. When you’ve been
+granted access to Gemini 3 Pro, you’ll receive an acceptance email to your
+submitted email address.
+
+## How to use Gemini 3 Pro with Gemini CLI
+
+Once you receive your acceptance email–or if you are automatically granted
+access–you still need to enable Gemini 3 Pro within Gemini CLI.
+
+To enable Gemini 3 Pro, use the `/settings` command in Gemini CLI and set
+**Preview Features** to `true`.
+
+For more information, see [Gemini CLI Settings](../cli/settings.md).
+
+### Usage limits and fallback
+
+Gemini CLI will tell you when you reach your Gemini 3 Pro daily usage limit.
+When you encounter that limit, you’ll be given the option to switch to Gemini
+2.5 Pro, upgrade for higher limits, or stop. You’ll also be told when your usage
+limit resets and Gemini 3 Pro can be used again.
+
+Similarly, when you reach your daily usage limit for Gemini 2.5 Pro, you’ll see
+a message prompting fallback to Gemini 2.5 Flash.
+
+### Capacity errors
+
+There may be times when the Gemini 3 Pro model is overloaded. When that happens,
+Gemini CLI will ask you to decide whether you want to keep trying Gemini 3 Pro
+or fallback to Gemini 2.5 Pro.
+
+**Note:** The **Keep trying** option uses exponential backoff, in which Gemini
+CLI waits longer between each retry, when the system is busy. If the retry
+doesn't happen immediately, please wait a few minutes for the request to
+process.
+
+## Model selection & routing types
+
+When using Gemini CLI, you may want to control how your requests are routed
+between models. By default, Gemini CLI uses **Auto** routing.
+
+When using Gemini 3 Pro, you may want to use Auto routing or Pro routing to
+manage your usage limits:
+
+- **Auto routing:** Auto routing first determines whether a prompt involves a
+  complex or simple operation. For simple prompts, it will automatically use
+  Gemini 2.5 Flash. For complex prompts, if Gemini 3 Pro is enabled, it will use
+  Gemini 3 Pro; otherwise, it will use Gemini 2.5 Pro.
+- **Pro routing:** If you want to ensure your task is processed by the most
+  capable model, use `/model` and select **Pro**. Gemini CLI will prioritize the
+  most capable model available, including Gemini 3 Pro if it has been enabled.
+
+To learn more about selecting a model and routing, refer to
+[Gemini CLI Model Selection](../cli/model.md).
+
+## Need help?
+
+If you need help, we recommend searching for an existing
+[GitHub issue](https://github.com/google-gemini/gemini-cli/issues). If you
+cannot find a GitHub issue that matches your concern, you can
+[create a new issue](https://github.com/google-gemini/gemini-cli/issues/new/choose).

-# Multi File Read Tool (`read_many_files`)
-
-This document describes the `read_many_files` tool for the Gemini CLI.
-
-## Description
-
-Use `read_many_files` to read content from multiple files specified by paths or
-glob patterns. The behavior of this tool depends on the provided files:
-
-- For text files, this tool concatenates their content into a single string.
-- For image (e.g., PNG, JPEG), PDF, audio (MP3, WAV), and video (MP4, MOV)
-  files, it reads and returns them as base64-encoded data, provided they are
-  explicitly requested by name or extension.
-
-`read_many_files` can be used to perform tasks such as getting an overview of a
-codebase, finding where specific functionality is implemented, reviewing
-documentation, or gathering context from multiple configuration files.
-
-**Note:** `read_many_files` looks for files following the provided paths or glob
-patterns. A directory path such as `"/docs"` will return an empty result; the
-tool requires a pattern such as `"/docs/*"` or `"/docs/*.md"` to identify the
-relevant files.
-
-### Arguments
-
-`read_many_files` takes the following arguments:
-
-- `paths` (list[string], required): An array of glob patterns or paths relative
-  to the tool's target directory (e.g., `["src/**/*.ts"]`,
-  `["README.md", "docs/*", "assets/logo.png"]`).
-- `exclude` (list[string], optional): Glob patterns for files/directories to
-  exclude (e.g., `["**/*.log", "temp/"]`). These are added to default excludes
-  if `useDefaultExcludes` is true.
-- `include` (list[string], optional): Additional glob patterns to include. These
-  are merged with `paths` (e.g., `["*.test.ts"]` to specifically add test files
-  if they were broadly excluded, or `["images/*.jpg"]` to include specific image
-  types).
-- `recursive` (boolean, optional): Whether to search recursively. This is
-  primarily controlled by `**` in glob patterns. Defaults to `true`.
-- `useDefaultExcludes` (boolean, optional): Whether to apply a list of default
-  exclusion patterns (e.g., `node_modules`, `.git`, non image/pdf binary files).
-  Defaults to `true`.
-- `respect_git_ignore` (boolean, optional): Whether to respect .gitignore
-  patterns when finding files. Defaults to true.
-
-## How to use `read_many_files` with the Gemini CLI
-
-`read_many_files` searches for files matching the provided `paths` and `include`
-patterns, while respecting `exclude` patterns and default excludes (if enabled).
-
-- For text files: it reads the content of each matched file (attempting to skip
-  binary files not explicitly requested as image/PDF) and concatenates it into a
-  single string, with a separator `--- {filePath} ---` between the content of
-  each file. Uses UTF-8 encoding by default.
-- The tool inserts a `--- End of content ---` after the last file.
-- For image and PDF files: if explicitly requested by name or extension (e.g.,
-  `paths: ["logo.png"]` or `include: ["*.pdf"]`), the tool reads the file and
-  returns its content as a base64 encoded string.
-- The tool attempts to detect and skip other binary files (those not matching
-  common image/PDF types or not explicitly requested) by checking for null bytes
-  in their initial content.
-
-Usage:
-
-```
-read_many_files(paths=["Your files or paths here."], include=["Additional files to include."], exclude=["Files to exclude."], recursive=False, useDefaultExcludes=false, respect_git_ignore=true)
-```
-
-## `read_many_files` examples
-
-Read all TypeScript files in the `src` directory:
-
-```
-read_many_files(paths=["src/**/*.ts"])
-```
-
-Read the main README, all Markdown files in the `docs` directory, and a specific
-logo image, excluding a specific file:
-
-```
-read_many_files(paths=["README.md", "docs/**/*.md", "assets/logo.png"], exclude=["docs/OLD_README.md"])
-```
-
-Read all JavaScript files but explicitly include test files and all JPEGs in an
-`images` folder:
-
-```
-read_many_files(paths=["**/*.js"], include=["**/*.test.js", "images/**/*.jpg"], useDefaultExcludes=False)
-```
-
-## Important notes
-
-- **Binary file handling:**
-  - **Image/PDF/Audio/Video files:** The tool can read common image types (PNG,
-    JPEG, etc.), PDF, audio (mp3, wav), and video (mp4, mov) files, returning
-    them as base64 encoded data. These files _must_ be explicitly targeted by
-    the `paths` or `include` patterns (e.g., by specifying the exact filename
-    like `video.mp4` or a pattern like `*.mov`).
-  - **Other binary files:** The tool attempts to detect and skip other types of
-    binary files by examining their initial content for null bytes. The tool
-    excludes these files from its output.
-- **Performance:** Reading a very large number of files or very large individual
-  files can be resource-intensive.
-- **Path specificity:** Ensure paths and glob patterns are correctly specified
-  relative to the tool's target directory. For image/PDF files, ensure the
-  patterns are specific enough to include them.
-- **Default excludes:** Be aware of the default exclusion patterns (like
-  `node_modules`, `.git`) and use `useDefaultExcludes=False` if you need to
-  override them, but do so cautiously.
