+description: Provides a step-by-step procedure for generating Gemini CLI changelog files based on github release information.
+---
+
+# Procedure: Updating Changelog for New Releases
+
+The following instructions are run by Gemini CLI when processing new releases.
+
+## Objective
+
+To standardize the process of updating the Gemini CLI changelog files for a new
+release, ensuring accuracy, consistency, and adherence to project style
+guidelines.
+
+## Release Types
+
+This skill covers two types of releases:
+
+*   **Standard Releases:** Regular, versioned releases that are announced to all
+    users. These updates modify `docs/changelogs/latest.md` and
+    `docs/changelogs/index.md`.
+*   **Preview Releases:** Pre-release versions for testing and feedback. These
+    updates only modify `docs/changelogs/preview.md`.
+
+Ignore all other releases, such as nightly releases.
+
+### Expected Inputs
+
+Regardless of the type of release, the following information is expected:
+
+*   **New version number:** The version number for the new release
+    (e.g., `v0.27.0`).
+*   **Release date:** The date of the new release (e.g., `2026-02-03`).
+*   **Raw changelog data:** A list of all pull requests and changes
+    included in the release, in the format `description by @author in
+    #pr_number`.
+*   **Previous version number:** The version number of the last release can be
+    calculated by decreasing the minor version number by one and setting the
+    patch or bug fix version number.
+
+## Procedure
+
+### Initial Setup
+
+1.  Identify the files to be modified: 
+
+    For standard releases, update `docs/changelogs/latest.md` and
+    `docs/changelogs/index.md`. For preview releases, update
+    `docs/changelogs/preview.md`.
+
+2.  Activate the `docs-writer` skill.
+
+### Analyze Raw Changelog Data
+
+1.  Review the complete list of changes. If it is a patch or a bug fix with few
+    changes, skip to the "Update `docs/changelogs/latest.md` or
+    `docs/changelogs/preview.md`" section.
+
+2.  Group related changes into high-level categories such as
+    important features, "UI/UX Improvements", and "Bug Fixes". Use the existing
+    announcements in `docs/changelogs/index.md` as an example.
+
+### Create Highlight Summaries
+
+Create two distinct versions of the release highlights.
+
+**Important:** Carefully inspect highlights for "experimental" or
+"preview" features before public announcement, and do not include them.
+
+#### Version 1: Comprehensive Highlights (for `latest.md` or `preview.md`)
+
+Write a detailed summary for each category focusing on user-facing
+impact.
+
+#### Version 2: Concise Highlights (for `index.md`)
+
+Skip this step for preview releases.
+
+Write concise summaries including the primary PR and author
+(e.g., `([#12345](link) by @author)`).
+
+### Update `docs/changelogs/latest.md` or `docs/changelogs/preview.md`
+
+1. Read current content and use `write_file` to replace it with the new
+  version number, and date.
+  
+  If it is a patch or bug fix with few changes, simply add these
+  changes to the "What's Changed" list. Otherwise, replace comprehensive
+  highlights, and the full "What's Changed" list. 
+
+2. For each item in the "What's Changed" list, keep usernames in plaintext, and
+  add github links for each issue number. Example:
+
+  "- feat: implement /rewind command by @username in
+  [#12345](https://github.com/google-gemini/gemini-cli/pull/12345)"
+
+3. Skip entries by @gemini-cli-robot.
+
+4. Do not add the "New Contributors" section.
+
+5. Update the "Full changelog:" link by doing one of following:
+
+   If it is a patch or bug fix with few changes, retain the original link
+   but replace the latter version with the new version. For example, if the
+   patch is version is "v0.28.1", replace the latter version:
+   "https://github.com/google-gemini/gemini-cli/compare/v0.27.0...v0.28.0" with
+   "https://github.com/google-gemini/gemini-cli/compare/v0.27.0...v0.28.1".
+   
+   Otherwise, for minor and major version changes, replace the link with the
+   one included at the end of the changelog data.
+
+6. Ensure lines are wrapped to 80 characters.
+
+### Update `docs/changelogs/index.md`
+
+Skip this step for patches, bug fixes, or preview releases.
+
+Insert a new "Announcements" section for the new version directly
+above the previous version's section. Ensure lines are wrapped to
+80 characters.
+
+### Finalize
+
+Run `npm run format` to ensure consistency.

 # `docs-writer` skill instructions
 
-As an expert technical writer and editor for the Gemini CLI project, your goal
-is to produce and refine documentation that is accurate, clear, consistent, and
-easy for users to understand. You must adhere to the documentation contribution
-process outlined in `CONTRIBUTING.md`.
+As an expert technical writer and editor for the Gemini CLI project, you produce
+accurate, clear, and consistent documentation. When asked to write, edit, or
+review documentation, you must ensure the content strictly adheres to the
+provided documentation standards and accurately reflects the current codebase.
+Adhere to the contribution process in `CONTRIBUTING.md` and the following
+project standards.
 
-## Step 1: Understand the goal and create a plan
+## Phase 1: Documentation standards
 
-1.  **Clarify the request:** Fully understand the user's documentation request.
-    Identify the core feature, command, or concept that needs work.
-2.  **Differentiate the task:** Determine if the request is primarily for
-    **writing** new content or **editing** existing content. If the request is
-    ambiguous (e.g., "fix the docs"), ask the user for clarification.
-3.  **Formulate a plan:** Create a clear, step-by-step plan for the required
-    changes.
+Adhering to these principles and standards when writing, editing, and reviewing.
 
-## Step 2: Investigate and gather information
+### Voice and tone
+Adopt a tone that balances professionalism with a helpful, conversational
+approach.
 
-1.  **Read the code:** Thoroughly examine the relevant codebase, primarily
-    within
-    the `packages/` directory, to ensure your work is backed by the
-    implementation and to identify any gaps.
-2.  **Identify files:** Locate the specific documentation files in the `docs/`
-    directory that need to be modified. Always read the latest version of a file
-    before you begin work.
-3.  **Check for connections:** Consider related documentation. If you change a
-    command's behavior, check for other pages that reference it. If you add a new
-    page, check if `docs/sidebar.json` needs to be updated. Make sure all
-    links are up to date.
+- **Perspective and tense:** Address the reader as "you." Use active voice and
+  present tense (e.g., "The API returns...").
+- **Tone:** Professional, friendly, and direct. 
+- **Clarity:** Use simple vocabulary. Avoid jargon, slang, and marketing hype.
+- **Global Audience:** Write in standard US English. Avoid idioms and cultural
+  references.
+- **Requirements:** Be clear about requirements ("must") vs. recommendations
+  ("we recommend"). Avoid "should."
+- **Word Choice:** Avoid "please" and anthropomorphism (e.g., "the server
+  thinks"). Use contractions (don't, it's).
 
-## Step 3: Write or edit the documentation
+### Language and grammar
+Write precisely to ensure your instructions are unambiguous.
 
-1.  **Follow the style guide:** Adhere to the rules in
-    `references/style-guide.md`. Read this file to understand the project's
-    documentation standards.
-2.   Ensure the new documentation accurately reflects the features in the code.
-3.  **Use `replace` and `write_file`:** Use file system tools to apply your
-    planned changes. For small edits, `replace` is preferred. For new files or
-    large rewrites, `write_file` is more appropriate.
+- **Abbreviations:** Avoid Latin abbreviations; use "for example" (not "e.g.")
+  and "that is" (not "i.e.").
+- **Punctuation:** Use the serial comma. Place periods and commas inside
+  quotation marks.
+- **Dates:** Use unambiguous formats (e.g., "January 22, 2026").
+- **Conciseness:** Use "lets you" instead of "allows you to." Use precise,
+  specific verbs.
+- **Examples:** Use meaningful names in examples; avoid placeholders like
+  "foo" or "bar."
+
+### Formatting and syntax
+Apply consistent formatting to make documentation visually organized and
+accessible.
+
+- **Overview paragraphs:** Every heading must be followed by at least one
+  introductory overview paragraph before any lists or sub-headings.
+- **Text wrap:** Wrap text at 80 characters (except long links or tables).
+- **Casing:** Use sentence case for headings, titles, and bolded text.
+- **Naming:** Always refer to the project as `Gemini CLI` (never
+  `the Gemini CLI`).
+- **Lists:** Use numbered lists for sequential steps and bulleted lists
+  otherwise. Keep list items parallel in structure.
+- **UI and code:** Use **bold** for UI elements and `code font` for filenames,
+  snippets, commands, and API elements. Focus on the task when discussing
+  interaction.
+- **Links:** Use descriptive anchor text; avoid "click here." Ensure the link
+  makes sense out of context.
+- **Accessibility:** Use semantic HTML elements correctly (headings, lists, 
+  tables).
+- **Media:** Use lowercase hyphenated filenames. Provide descriptive alt text
+  for all images.
+
+### Structure
+- **BLUF:** Start with an introduction explaining what to expect.
+- **Experimental features:** If a feature is clearly noted as experimental,
+add the following note immediately after the introductory paragraph:
+  `> **Note:** This is a preview feature currently under active development.`
+- **Headings:** Use hierarchical headings to support the user journey.
+- **Procedures:** 
+  - Introduce lists of steps with a complete sentence.
+  - Start each step with an imperative verb.
+  - Number sequential steps; use bullets for non-sequential lists.
+  - Put conditions before instructions (e.g., "On the Settings page, click...").
+  - Provide clear context for where the action takes place.
+  - Indicate optional steps clearly (e.g., "Optional: ...").
+- **Elements:** Use bullet lists, tables, notes (`> **Note:**`), and warnings 
+  (`> **Warning:**`).
+- **Avoid using a table of contents:** If a table of contents is present, remove
+  it.
+- **Next steps:** Conclude with a "Next steps" section if applicable.
+
+## Phase 2: Preparation
+Before modifying any documentation, thoroughly investigate the request and the
+surrounding context. 
+
+1.  **Clarify:** Understand the core request. Differentiate between writing new
+    content and editing existing content. If the request is ambiguous (e.g.,
+    "fix the docs"), ask for clarification.
+2.  **Investigate:** Examine relevant code (primarily in `packages/`) for
+    accuracy.
+3.  **Audit:** Read the latest versions of relevant files in `docs/`.
+4.  **Connect:** Identify all referencing pages if changing behavior. Check if
+    `docs/sidebar.json` needs updates.
+5.  **Plan:** Create a step-by-step plan before making changes.
+
+## Phase 3: Execution
+Implement your plan by either updating existing files or creating new ones
+using the appropriate file system tools. Use `replace` for small edits and
+`write_file` for new files or large rewrites.
+
+### Editing existing documentation
+Follow these additional steps when asked to review or update existing
+documentation.
+
+- **Gaps:** Identify areas where the documentation is incomplete or no longer
+  reflects existing code.
+- **Structure:** Apply "Structure (New Docs)" rules (BLUF, headings, etc.) when 
+  adding new sections to existing pages.
+- **Tone:** Ensure the tone is active and engaging. Use "you" and contractions.
+- **Clarity:** Correct awkward wording, spelling, and grammar. Rephrase
+  sentences to make them easier for users to understand.
+- **Consistency:** Check for consistent terminology and style across all edited
+  documents.
 
 
+## Phase 4: Verification and finalization
+Perform a final quality check to ensure that all changes are correctly formatted
+and that all links are functional.
 
-### Sub-step: Editing existing documentation (as clarified in Step 1)

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

 ## Highlights
 
-- **Enhanced Agent and Skill Capabilities:** This release introduces the new
-  `skill-creator` built-in skill, enables Agent Skills by default, and adds a
-  generalist agent to improve task routing. Security for skill installation has
-  also been enhanced with new consent prompts.
-- **Improved UI and UX:** A new "Rewind" feature lets you walk back through
-  conversation history. We've also added an `/introspect` command for debugging
-  and unified various shell confirmation dialogs for a more consistent user
-  experience.
-- **Core Stability and Performance:** This release includes significant
-  performance improvements, including a fix for PDF token estimation,
-  optimizations for large inputs, and prevention of OOM crashes. Key memory
-  management components like `LRUCache` have also been updated.
-- **Scheduler and Policy Refactoring:** The core tool scheduler has been
-  decoupled into distinct orchestration, policy, and confirmation components,
-  and we've added an experimental event-driven scheduler to improve performance
-  and reliability.
+- **Event-Driven Architecture:** The CLI now uses an event-driven scheduler for
+  tool execution, improving performance and responsiveness. This includes
+  migrating non-interactive flows and sub-agents to the new scheduler.
+- **Enhanced User Experience:** This release introduces several UI/UX
+  improvements, including queued tool confirmations and the ability to expand
+  and collapse large pasted text blocks. The `Settings` dialog has been improved
+  to reduce jitter and preserve focus.
+- **Agent and Skill Improvements:** Agent Skills have been promoted to a stable
+  feature. Sub-agents now use a JSON schema for input and are tracked by an
+  `AgentRegistry`.
+- **New `/rewind` Command:** A new `/rewind` command has been implemented to
+  allow users to go back in their session history.
+- **Improved Shell and File Handling:** The shell tool's output format has been
+  optimized, and the CLI now gracefully handles disk-full errors during chat
+  recording. A bug in detecting already added paths has been fixed.
+- **Linux Clipboard Support:** Image pasting capabilities for Wayland and X11 on
+  Linux have been added.

+# Plan Mode (experimental) <!-- omit in toc -->
+
+Plan Mode is a safe, read-only mode for researching and designing complex
+changes. It prevents modifications while you research, design and plan an
+implementation strategy.
+
+> **Note: Plan Mode is currently an experimental feature.**
+>
+> Experimental features are subject to change. To use Plan Mode, enable it via
+> `/settings` (search for `Plan`) or add the following to your `settings.json`:
+>
+> ```json
+> {
+>   "experimental": {
+>     "plan": true
+>   }
+> }
+> ```
+>
+> Your feedback is invaluable as we refine this feature. If you have ideas,
+> suggestions, or encounter issues:
+>
+> - Use the `/bug` command within the CLI to file an issue.
+> - [Open an issue](https://github.com/google-gemini/gemini-cli/issues) on
+>   GitHub.

+
+## Starting in Plan Mode
+
+You can configure Gemini CLI to start directly in Plan Mode by default:
+
+1.  Type `/settings` in the CLI.
+2.  Search for `Approval Mode`.
+3.  Set the value to `Plan`.
+
+Other ways to start in Plan Mode:
+
+- **CLI Flag:** `gemini --approval-mode=plan`
+- **Manual Settings:** Manually update your `settings.json`:
+
+  ```json
+  {
+    "tools": {
+      "approvalMode": "plan"
+    }
+  }
+  ```
+
+## How to use Plan Mode
+
+### Entering Plan Mode
+
+You can enter Plan Mode in three ways:
+
+1.  **Keyboard Shortcut:** Press `Shift+Tab` to cycle through approval modes
+    (`Default` -> `Plan` -> `Auto-Edit`).
+2.  **Command:** Type `/plan` in the input box.
+3.  **Natural Language:** Ask the agent to "start a plan for...".
+
+### The Planning Workflow
+
+1.  **Requirements:** The agent clarifies goals using `ask_user`.
+2.  **Exploration:** The agent uses read-only tools (like [`read_file`]) to map
+    the codebase and validate assumptions.
+3.  **Planning:** A detailed plan is written to a temporary Markdown file.
+4.  **Review:** You review the plan.
+    - **Approve:** Exit Plan Mode and start implementation (switching to
+      Auto-Edit or Default approval mode).
+    - **Iterate:** Provide feedback to refine the plan.
+
+### Exiting Plan Mode
+
+To exit Plan Mode:
+
+1. **Keyboard Shortcut:** Press `Shift+Tab` to cycle to the desired mode.
+1. **Tool:** The agent calls the `exit_plan_mode` tool to present the finalized
+   plan for your approval.
+
+## Tool Restrictions
+
+Plan Mode enforces strict safety policies to prevent accidental changes.
+
+These are the only allowed tools:
+
+- **FileSystem (Read):** [`read_file`], [`list_directory`], [`glob`]
+- **Search:** [`grep_search`], [`google_web_search`]
+- **Interaction:** `ask_user`
+- **MCP Tools (Read):** Read-only [MCP tools] (e.g., `github_read_issue`,
+  `postgres_read_schema`) are allowed.
+- **Planning (Write):** [`write_file`] and [`replace`] ONLY allowed for `.md`
+  files in the `~/.gemini/tmp/<project>/plans/` directory.

-# Welcome to Gemini CLI documentation
+# Gemini CLI documentation
 
-This documentation provides a comprehensive guide to installing, using, and
-developing Gemini CLI, a tool that lets you interact with Gemini models through
-a command-line interface.
+Gemini CLI is an open-source AI agent that brings the power of Gemini directly
+into your terminal. It is designed to be a terminal-first, extensible, and
+powerful tool for developers, engineers, SREs, and beyond.
 
-## Gemini CLI overview
+Gemini CLI integrates with your local environment. It can read and edit files,
+execute shell commands, and search the web, all while maintaining your project
+context.
 
-Gemini CLI brings the capabilities of Gemini models to your terminal in an
-interactive Read-Eval-Print Loop (REPL) environment. Gemini CLI consists of a
-client-side application (`packages/cli`) that communicates with a local server
-(`packages/core`), which in turn manages requests to the Gemini API and its AI
-models. Gemini CLI also contains a variety of tools for tasks such as performing
-file system operations, running shells, and web fetching, which are managed by
-`packages/core`.
