fix(cli): restore format-preserving update logic while maintaining persistence fix

Added unit tests for:
1. comment-json trailing comma and comment handling.
2. Granular settings deletion in LoadedSettings.
3. Surgical migration logic in settings manager.
4. Search result multi-mapping for duplicate labels in SettingsDialog.
5. Hot-reload hydration logic in core Config.
6. end-to-end onReload payload in CLI config.
7. SettingsChanged event listener in gemini main loop.
8. Fixed all lint errors and TypeErrors in tests.

 - **Logging**: Do not leave `console.log`, `console.warn`, or `console.error` in

-- **State & Effects**: Ensure state initialization is explicit (e.g., use
-  `undefined` rather than `true` as a default if the state is truly unknown).

+- **State**: Ensure state initialization is explicit (e.g., use `undefined`
+  rather than `true` as a default if the state is truly unknown). Prefer a
+  reducer whenever practical. NEVER disable `react-hooks/exhaustive-deps`; fix
+  the code to correctly declare dependencies instead. Evaluate all the React
+  states in a component and ensure that the `useState` calls are necessary and
+  not cases where values could be derived on render. Ensure there are no stale
+  closures that are relying on a value from a previous render. React Components
+  that modify Settings should effectively use the `useSettingsStore` pattern.
+  Components that configure application Settings (e.g settings.json) are the
+  only reasonable case for unsaved changes to drive UX; in these cases, the
+  Settings store should only be written to on save. If the user experience does
+  not utilize unsaved changes because there is no option to exit without saving
+  or reverting the unsaved changes, then the component should directly read from
+  and write to the Settings store without holding pending changes in component
+  level UI state.
+- **Effect**: `useEffect` should not be used to synchronize React states, it
+  should only be used for genuine side effects that occur outside of React.
+  Contributors should be able to strongly justify the need for an effect.
+  Consider whether the effect should instead be inside an event handler, or
+  whether it is better off being computed on render. Carefully manage
+  `useEffect` dependencies.
 - **Context & Props**: Avoid excessive property drilling. Leverage existing
   providers, extend them, or propose a new one if necessary. Only use providers
   for properties that are consistent across the entire application.

 ## Highlights
 
-- **Chapters Narrative Flow:** Introduced tool-based topic grouping ("Chapters")
-  to provide better session structure and narrative continuity in long-running
-  tasks.
-- **Context Compression Service:** Implemented a dedicated service for advanced
-  context management, efficiently distilling conversation history to preserve
-  focus and tokens.
-- **Enhanced UI Stability & UX:** Introduced a new "Terminal Buffer" mode to
-  solve rendering flicker, along with selective topic expansion and improved
-  tool confirmation layouts.
-- **Context-Aware Policy Approvals:** Users can now grant persistent,
-  context-aware approvals for tools, significantly reducing manual confirmation
-  overhead for trusted workflows.
-- **Background Process Monitoring:** New tools for monitoring and inspecting
-  background shell processes, providing better visibility into asynchronous
-  tasks.
+- **Offline Search Support:** Bundled ripgrep binaries into the Single
+  Executable Application (SEA) to enable powerful codebase searching even in
+  environments without internet access.
+- **Enhanced Theme Customization:** Introduced GitHub-style colorblind-friendly
+  themes to improve accessibility and provide more personalized visual options.
+- **MCP Resource Management:** Added new tools for listing and reading Model
+  Context Protocol (MCP) resources, enhancing the agent's ability to discover
+  and utilize external data.
+- **Improved Narrative Flow:** Enabled topic update narrations by default to
+  provide better session structure and a clearer understanding of the agent's
+  current focus.
+- **Streamlined Local Model Setup:** Introduced a simplified `gemini gemma`
+  command for quickly setting up and running Gemma models locally.
+- **Prompt-Driven Memory Management:** Replaced the legacy `MemoryManagerAgent`
+  with a more efficient prompt-driven memory editing system across four tiers of
+  context.

 ## Highlights
 
-- **Refactored Subagents and Unified Tooling:** Consolidate subagent tools into
-  a single `invoke_subagent` tool, removed legacy wrapping tools, and improved
-  turn limits for codebase investigator.
-- **Advanced Memory and Skill Management:** Introduced `/memory` inbox for
-  reviewing extracted skills and added skill patching support, enhancing agent
-  learning and persistence.
-- **Expanded Test and Evaluation Infrastructure:** Added memory and CPU
-  performance integration test harnesses and generalized evaluation
-  infrastructure for better suite organization.
-- **Sandbox and Security Hardening:** Centralized sandbox paths for Linux and
-  macOS, enforced read-only security for async git worktree resolution, and
-  optimized Windows sandbox initialization.
-- **Enhanced CLI UX and UI Stability:** Improved scroll momentum, added a
-  `debugRainbow` setting, and resolved various memory leaks and PTY exhaustion
-  issues for a smoother terminal experience.
+- **Real-Time Voice Mode:** Implemented a new real-time voice mode supporting
+  both cloud and local backends for a more interactive experience.
+- **Enhanced Security & Trust:** Enforced workspace trust in headless mode and
+  secured `.env` file loading to improve system integrity.
+- **Expanded Model Support:** Added experimental support for Gemma 4 models in
+  both core and CLI packages.
+- **Improved Core Infrastructure:** Wired up new `ContextManager` and
+  `AgentChatHistory` for better state management, and optimized boot performance
+  by fetching experiments and quota asynchronously.
+- **New Developer Tools & UX:** Added support for output redirection for CLI
+  commands, manual session UUIDs via command-line arguments, and persistent
+  auto-memory scratchpad for skill extraction.

 # Creating Agent Skills
 
-This guide provides an overview of how to create your own Agent Skills to extend
-the capabilities of Gemini CLI.
+Agent Skills let you extend Gemini CLI with specialized expertise, procedural
+workflows, and task-specific resources. This guide walks you through both
+automated and manual methods for creating and organizing your skills.
 
-## Getting started: The `skill-creator` skill

-> "create a new skill called 'code-reviewer'"
+> "Create a new skill called 'code-reviewer' that analyzes local files for
+> common errors and style violations."
 
-Gemini CLI will then use the `skill-creator` to generate the skill:

 3.  Create the standard resource directories: `scripts/`, `references/`, and
     `assets/`.
 
-## Manual skill creation
+Once created, you can find your new skill in `.gemini/skills/code-reviewer/`.
 
-If you prefer to create skills manually:
+## Manual creation
 
 1.  **Create a directory** for your skill (for example, `my-new-skill/`).
 2.  **Create a `SKILL.md` file** inside the new directory.
 
-To add additional resources that support the skill, refer to the skill
-structure.
+### 1. Create the directory structure
 
-## Skill structure
+The first step is to create the necessary folders for your skill and its
+scripts.
 
-A skill is a directory containing a `SKILL.md` file at its root.
+**macOS/Linux**
 
-### Folder structure
+```bash
+mkdir -p .gemini/skills/code-reviewer/scripts
+```
+
+**Windows (PowerShell)**
+
+```powershell
+New-Item -ItemType Directory -Force -Path ".gemini\skills\code-reviewer\scripts"
+```
+
+### 2. Define the skill (`SKILL.md`)
+
+The `SKILL.md` file defines the skill's purpose and instructions for the agent.
+Create a file at `.gemini/skills/code-reviewer/SKILL.md`.
+
+```markdown
+---
+name: code-reviewer
+description:
+  Expertise in reviewing code changes for correctness, security, and style. Use
+  when the user asks to "review" their code or a PR.
+---
+
+# Code Reviewer Instructions
+
+You act as a senior software engineer specialized in code quality. When this
+skill is active, you MUST:
+
+1.  **Analyze**: Review the provided code for logical errors, security
+    vulnerabilities, and style violations.
+2.  **Review**: Use the bundled `scripts/review.js` utility to perform an
+    automated check.
+3.  **Feedback**: Provide constructive feedback, clearly distinguishing between
+    critical issues and minor improvements.
+```
+
+### 3. Add the tool logic
+
+Skills can bundle resources like scripts to perform deterministic tasks. Create
+a file at `.gemini/skills/code-reviewer/scripts/review.js`.
+
+```javascript
+// .gemini/skills/code-reviewer/scripts/review.js
+const file = process.argv[2];
+
+if (!file) {
+  console.error('Usage: node review.js <file>');
+  process.exit(1);
+}
+
+console.log(`Reviewing ${file}...`);
+// Simple mock review logic
+setTimeout(() => {
+  console.log(`Result: Success (No major issues found in ${file})`);
+}, 500);
+```
+
+### 4. Test the skill
+
+Gemini CLI automatically discovers skills in the `.gemini/skills` directory.
+
+1.  Start a new session and ask a question that triggers the skill's
+    description: "Can you review index.js"
+2.  Gemini identifies the request matches the `code-reviewer` description and
+    asks for permission to activate it.
+3.  Once you approve, Gemini executes the bundled script:
+    `node .gemini/skills/code-reviewer/scripts/review.js index.js`
+
+To determine whether your skill has been correctly loaded, run the command:
+
+```bash
+/skills
+```
+
+### 5. Optional: Share your skill
+
+You can share your skills in several ways depending on your target audience.
+
+- **Workspace skills**: Commit your skill to a `.gemini/skills/` directory in
+  your project repository.
+- **Extensions**: Bundle your skill within a
+  [Gemini CLI extension](../extensions/writing-extensions.md).
+- **Git repositories**: Share the skill directory as a standalone Git repo and
+  install it using `gemini skills install <url>`.
+
+---
+
+## Core concepts
+
+Now that you've built your first skill, let's explore the core components and
+workflows for developing more complex expertise.
+
+### Skill structure
 
 While a `SKILL.md` file is the only required component, we recommend the
-following structure for organizing your skill's resources:

-### `SKILL.md` file
+When a skill is activated, the model is granted access to this entire directory.
+You can instruct the model to use the tools and files found within these
+folders.
 
-The `SKILL.md` file is the core of your skill. This file uses YAML frontmatter
-for metadata and Markdown for instructions. For example:
+### Metadata and triggers
 
-```markdown
----
-name: code-reviewer
-description:
-  Use this skill to review code. It supports both local changes and remote Pull
-  Requests.
----
-
-# Code Reviewer
-
-This skill guides the agent in conducting thorough code reviews.
-
-## Workflow
-
-### 1. Determine Review Target
-
-- **Remote PR**: If the user gives a PR number or URL, target that remote PR.
-- **Local Changes**: If changes are local... ...
-```
+The `SKILL.md` file uses YAML frontmatter for metadata.
 
 - **`name`**: A unique identifier for the skill. This should match the directory
   name.
-- **`description`**: A description of what the skill does and when Gemini should
-  use it.
-- **Body**: The Markdown body of the file contains the instructions that guide
-  the agent's behavior when the skill is active.
+- **`description`**: **CRITICAL.** This is how Gemini decides when to use the
+  skill. Be specific about the tasks it handles and the keywords that should
+  trigger it.
+
+### Discovery tiers
+
+Gemini CLI discovers skills from several locations, following a specific order
+of precedence (lowest to highest):
+
+1.  **Built-in Skills**: Included with Gemini CLI (pre-approved).
+2.  **Extension Skills**: Bundled within [extensions](../extensions/).
+3.  **User Skills**: `~/.gemini/skills/` or the `~/.agents/skills/` alias.
+4.  **Workspace Skills**: `.gemini/skills/` or the `.agents/skills/` alias.
+
+### Discovery aliases
+
+You can use `.agents/skills` as an alternative to `.gemini/skills`. This alias
+is compatible with other AI agent tools following the
+[Agent Skills](https://agentskills.io) standard.
+
+## Advanced development
+
+Once you've built a basic skill, you can use specialized scripts and workflows
+to streamline your development process.
+
+### Creation scripts
+
+If you are developing a skill and want to use the same scripts the built-in
+tools use, you can find them in the core package. These scripts help automate
+the initialization, validation, and packaging of skills.
+
+- **Initialize**: `node scripts/init_skill.cjs <name> --path <dir>`
+- **Validate**: `node scripts/validate_skill.cjs <path/to/skill>`
+- **Package**: `node scripts/package_skill.cjs <path/to/skill>` (Creates a
+  `.skill` zip file)
+
+### Linking for local development
+
+If you are developing a skill in a separate directory, you can link it to your
+user skills directory for testing:
+
+```bash
+gemini skills link .
+```

 ### 2. Container-based (Docker/Podman)
 
-Cross-platform sandboxing with complete process isolation.
+Cross-platform sandboxing with complete process isolation using container
+technology. By default, it uses the `ghcr.io/google/gemini-cli:latest` image.
 
-**Note**: Requires building the sandbox image locally or using a published image
-from your organization's registry.
+**Prerequisites:**
+
+- Docker or Podman must be installed and running on your system.
+
+**How it works (Workspace directory):**
+
+Inside the sandbox container, your current working directory is mounted at the
+**exact same absolute path** as it is on your host machine. For example, if you
+run the CLI from `/Users/you/project` on your host machine, the sandbox will
+mount your local project folder and operate within `/Users/you/project` inside
+the container. This allows the AI to seamlessly read and modify your project
+files while remaining isolated from the rest of your system.
+
+**Quick setup:**
+
+To enable Docker sandboxing, run Gemini CLI with the sandbox flag and specify
+Docker as the provider:
+
+```bash
+# Using the environment variable (Recommended)
+export GEMINI_SANDBOX=docker
+gemini -p "build the project"
+
+# Or configure it permanently in your settings.json
+# {"tools": {"sandbox": "docker"}}
+```
+
+**Customizing the Sandbox Image:**
+
+If your project requires specific dependencies, you can specify a custom image
+name or have Gemini CLI build one for you automatically. You can use any Docker
+or Podman image as your sandbox, provided it has standard shell utilities (like
+`bash`) available.
+
+**Option A: Using an existing custom image (e.g., Artifact Registry)**
+
+To configure a custom image that is hosted on a registry (or built locally),
+update your `settings.json` to use an object for the sandbox configuration, or
+set the `GEMINI_SANDBOX_IMAGE` environment variable.
+
+_Example: Configuring via `settings.json`_
+
+```json
+{
+  "tools": {
+    "sandbox": {
+      "command": "docker",
+      "image": "us-central1-docker.pkg.dev/my-project/my-repo/my-custom-sandbox:latest"
+    }
+  }
+}
+```
+
+_Example: Configuring via environment variable_
+
+```bash
+export GEMINI_SANDBOX_IMAGE="us-central1-docker.pkg.dev/my-project/my-repo/my-custom-sandbox:latest"
+```
+
+**Option B: Building a local custom image automatically**
+
+If you prefer to define your environment as code, you can provide a Dockerfile
+and Gemini CLI will build the image automatically.
+
+1.  Create a `.gemini/sandbox.Dockerfile` in your project root.
+2.  Ensure you have the `gh` CLI installed and authenticated (if you are using
+    the default `ghcr.io/google/gemini-cli` image as a base).
+3.  Run your command with the `BUILD_SANDBOX` environment variable set:
+
+```bash

+```

@@ -188,59 +315,49 @@ This mechanism ensures you don't have to manually re-run commands with more
 permissive sandbox settings, while still maintaining control over what the AI
 can access.
 
-## Quickstart
+### Including files outside the workspace
+
+By default, the sandbox only has access to the current project workspace. If you
+need the sandbox to have permission to operate on certain files or directories
+from the local file system outside of the project workspace, you can mount them
+using the `SANDBOX_MOUNTS` environment variable.
+
+Provide a comma-separated list of mount definitions in the format
+`from:to:opts`. If `to` is omitted, it defaults to the same path as `from`. If
+`opts` is omitted, it defaults to `ro` (read-only). Note that the `from` path
+must be an absolute path.
+
+**Example**:
 
 ```bash
-# Enable sandboxing with command flag
-gemini -s -p "analyze the code structure"
+export SANDBOX_MOUNTS="/path/on/host:/path/in/container:rw,/another/path:ro"
 ```
 
-**Use environment variable**
+## Running inside a Docker container
 
-**macOS/Linux**
+If you are running Gemini CLI itself from within an official or custom Docker
+container and want to enable sandboxing, you must share the host's Docker socket
+and ensure your workspace paths align.
+
+1.  **Mount the Docker socket**: Map `/var/run/docker.sock` so the CLI can spawn
+    sibling sandbox containers via the host's Docker daemon.
+2.  **Align workspace paths**: The path to your workspace inside the container
+    must exactly match the absolute path on the host. Because the sandbox
+    container is spawned by the host's Docker daemon, it resolves volume mounts

+# Agent Skill best practices
+
+Create high-quality, reliable Agent Skills by following these established design
+principles and patterns.
+
+## Design for discovery
+
+The most important part of a skill is its `description`. This is the only
+information the model has before activation.
+
+- **Be specific**: Use keywords that are likely to appear in user prompts (for
+  example, "audit," "security," "refactor," "migration").
+- **Define the trigger**: Clearly state _when_ the skill should be used (for
+  example, "Use this skill when the user asks to review a PR for performance
+  regressions").
+- **Avoid overlap**: Ensure your skill descriptions are distinct from one
+  another and from the general capabilities of the model.
+
+## Progressive disclosure
+
+The "context window" is a shared resource. Use a three-level loading system to
+manage context efficiently.
+
+1.  **Metadata (name + description)**: Always in context (~100 words).
+2.  **`SKILL.md` body**: Loaded only after the skill triggers (<5k words).
+3.  **Bundled resources**: Loaded only as needed by the model.
+
+**Best practice**: Keep the `SKILL.md` body focused on core procedural
+instructions. Move detailed reference material, schemas, and examples into
+separate files in a `references/` directory.
+
+## Degrees of freedom
+
+Match the level of instruction specificity to the task's fragility.
+
+- **High freedom (text-based instructions)**: Use when multiple approaches are
+  valid or decisions depend heavily on context.
+- **Medium freedom (pseudocode or scripts with parameters)**: Use when a
+  preferred pattern exists but some variation is acceptable.
+- **Low freedom (specific scripts, few parameters)**: Use when operations are
+  fragile and error-prone, or a specific sequence MUST be followed.
+
+## Bundle resources effectively
+
+Leverage the skill's ability to include scripts and assets to extend the agent's
+capabilities.
+
+- **Use scripts for deterministic tasks**: If a task can be automated with a
+  script (for example, running a linter, fetching data from an API), bundle it
+  in the `scripts/` folder.
+- **Agentic ergonomics**: Ensure scripts output LLM-friendly stdout. Suppress
+  verbose tracebacks and provide clear, concise success/failure messages.
+- **Provide templates**: Include common file headers or boilerplate code in the
+  `assets/` folder to ensure the agent produces consistent output.
+
+## Anatomy of a great skill
+
+A well-structured skill directory organizes its resources into specialized
+sub-folders.
+
+```text
+my-skill/
+├── SKILL.md       (Required) Core instructions and metadata
+├── scripts/       (Optional) Executable logic (Node.js, Python, etc.)
+├── references/    (Optional) Documentation to be loaded as needed
+└── assets/        (Optional) Templates and non-executable resources
+```
+
+## Security and privacy
+
+Design your skills with security in mind to protect your workspace and data.
+
+- **Avoid hardcoded secrets**: Never include API keys or passwords in your
+  skill's scripts or documentation.
+- **Review third-party skills**: Inspect the `SKILL.md` and scripts of any skill
+  before installing it from an untrusted source.
+- **Limit scope**: Design skills to be as focused as possible to minimize the
+  potential impact of errors.

+Agent Skills let you extend Gemini CLI with specialized expertise, procedural
+workflows, and task-specific resources. Based on the
 [Agent Skills](https://agentskills.io) open standard, a "skill" is a
 self-contained directory that packages instructions and assets into a
 discoverable capability.
 
-## Overview
-
-Unlike general context files ([`GEMINI.md`](./gemini-md.md)), which provide
+Unlike general context files ([GEMINI.md](./gemini-md.md)), which provide
 persistent workspace-wide background, Skills represent **on-demand expertise**.
-This allows Gemini to maintain a vast library of specialized capabilities—such
-as security auditing, cloud deployments, or codebase migrations—without
-cluttering the model's immediate context window.
+This lets Gemini CLI maintain a vast library of specialized capabilities—such as
+security auditing, cloud deployments, or codebase migrations—without cluttering
+the model's immediate context window.
 
-Gemini autonomously decides when to employ a skill based on your request and the
-skill's description. When a relevant skill is identified, the model "pulls in"
-the full instructions and resources required to complete the task using the
-`activate_skill` tool.
+## How it works
 
-## Key Benefits
-
-- **Shared Expertise:** Package complex workflows (like a specific team's PR
-  review process) into a folder that anyone can use.
-- **Repeatable Workflows:** Ensure complex multi-step tasks are performed
-  consistently by providing a procedural framework.
-- **Resource Bundling:** Include scripts, templates, or example data alongside
-  instructions so the agent has everything it needs.
-- **Progressive Disclosure:** Only skill metadata (name and description) is
-  loaded initially. Detailed instructions and resources are only disclosed when
-  the model explicitly activates the skill, saving context tokens.
-
-## Skill Discovery Tiers
-
-Gemini CLI discovers skills from three primary locations:
-
-1.  **Workspace Skills**: Located in `.gemini/skills/` or the `.agents/skills/`
-    alias. Workspace skills are typically committed to version control and
-    shared with the team.
-2.  **User Skills**: Located in `~/.gemini/skills/` or the `~/.agents/skills/`
-    alias. These are personal skills available across all your workspaces.
-3.  **Extension Skills**: Skills bundled within installed
-    [extensions](../extensions/index.md).
-
-**Precedence:** If multiple skills share the same name, higher-precedence
-locations override lower ones: **Workspace > User > Extension**.
-
-Within the same tier (user or workspace), the `.agents/skills/` alias takes
-precedence over the `.gemini/skills/` directory. This generic alias provides an
-intuitive path for managing agent-specific expertise that remains compatible
-across different AI agent tools.
-
-## Managing Skills
-
-### In an Interactive Session
-
-Use the `/skills` slash command to view and manage available expertise:
-
-- `/skills list` (default): Shows all discovered skills and their status.
-- `/skills link <path>`: Links agent skills from a local directory via symlink.
-- `/skills disable <name>`: Prevents a specific skill from being used.
-- `/skills enable <name>`: Re-enables a disabled skill.
-- `/skills reload`: Refreshes the list of discovered skills from all tiers.
-
-<!-- prettier-ignore -->
-> [!NOTE]
-> `/skills disable` and `/skills enable` default to the `user` scope. Use
-> `--scope workspace` to manage workspace-specific settings.
-
-### From the Terminal
-
-The `gemini skills` command provides management utilities:
-
-```bash
-# List all discovered skills
-gemini skills list
-
-# Link agent skills from a local directory via symlink

 5.  **Execution**: The model proceeds with the specialized expertise active. It
     is instructed to prioritize the skill's procedural guidance within reason.
 
-### Skill activation
+## Discovery tiers
 
-Once a skill is activated (typically by Gemini identifying a task that matches
-the skill's description and your approval), its specialized instructions and
-resources are loaded into the agent's context. A skill remains active and its
-guidance is prioritized for the duration of the session.
+Gemini CLI discovers skills from several locations, following a specific order
+of precedence (lowest to highest):
 
-## Creating your own skills
+1.  **Built-in skills**: Standard skills included with Gemini CLI that provide
+    foundational capabilities.
+2.  **Extension skills**: Skills bundled within installed
+    [extensions](../extensions/index.md).
+3.  **User skills**: Located in `~/.gemini/skills/` or the `~/.agents/skills/`
+    alias.
+4.  **Workspace skills**: Located in `.gemini/skills/` or the `.agents/skills/`
+    alias. Workspace skills are shared with your team via version control.
 
-To create your own skills, see the [Create Agent Skills](./creating-skills.md)
-guide.
+### Precedence and aliases
+
+If multiple skills share the same name, the version from the higher-precedence
+location is used. Within the same tier (user or workspace), the
+`.agents/skills/` alias takes precedence over the `.gemini/skills/` directory.
+
+The `.agents/skills/` alias provides an interoperable path for managing
+agent-specific expertise that remains compatible across different AI tools.
+
+## Key benefits
+
+Agent Skills provide several advantages for managing specialized knowledge and
+complex workflows.
+
+- **Shared expertise**: Package complex workflows (like a specific team's PR
+  review process) into a folder that anyone can use.
+- **Repeatable workflows**: Ensure complex multi-step tasks are performed
+  consistently by providing a procedural framework.
+- **Resource bundling**: Include scripts, templates, or example data alongside
+  instructions so the agent has everything it needs.
+- **Progressive disclosure**: Only skill metadata (name and description) is
+  loaded initially. Detailed instructions and resources are only disclosed when
+  the model explicitly activates the skill, saving context tokens.

+> `/skills disable` and `/skills enable` default to the `user` scope. Use
+> `--scope workspace` to manage workspace-specific settings.
+
+To see all available skills in your current session, use the `/skills list`
+command.
+
+## Managing skills
+
+You can manage Agent Skills through interactive session commands or directly
+from your terminal.
+
+### In an interactive session
+
+Use the `/skills` slash command to view and manage available expertise:
+
+- `/skills list [all] [nodesc]`: Shows discovered skills. Use `all` to include
+  built-in skills and `nodesc` to hide descriptions.
+- `/skills link <path> [--scope user|workspace]`: Links skills from a local
+  directory.
+- `/skills disable <name>`: Prevents a specific skill from being used.
+- `/skills enable <name>`: Re-enables a disabled skill.
+- `/skills reload` (or `/skills refresh`): Refreshes the list of discovered
+  skills from all tiers.
+
+### From the terminal
+
+The `gemini skills` command provides management utilities:
+
+```bash
+# List all discovered skills. Use --all to include built-in skills.
+gemini skills list --all
+
+# Install a skill from a Git repository or local directory.
+# Use --consent to skip the security confirmation prompt.
+gemini skills install https://github.com/user/repo.git --consent
+
+# Uninstall a skill.
+gemini skills uninstall my-skill --scope workspace
+```
+
+#### Command options
+
+The skill management commands support several global and command-specific
+options.
+
+- `--scope`: Either `user` (global, default) or `workspace` (local to the
+  project).
+- `--path`: The sub-directory within a Git repository containing the skill.
+- `--consent`: Acknowledge security risks and skip the interactive confirmation
+  during installation.

+Gemini CLI automatically discovers skills in the `.gemini/skills` directory (as
+well as the `.agents/skills` alias).
 
-Gemini CLI automatically discovers skills in the `.gemini/skills` directory. You
-can also use `.agents/skills` as a more generic alternative. Check that it found
-your new skill.
+To check if Gemini CLI found your new skill, use the `/skills list` command
+within an interactive session:
 
-**Command:** `/skills list`
+```bash
+/skills list
+```
 
-You should see `api-auditor` in the list of available skills.
+You should see `api-auditor` in the list of available skills. If you just added
+the files, you can run `/skills reload` to refresh the list without restarting
+the session.
+
+### If your skill doesn't appear
+
+If `/skills list` doesn't show your skill, check the following:
+
+1.  **The folder must be trusted (workspace skills only).** Skills under
+    `<workspace>/.gemini/skills/` are only loaded when the workspace folder is
+    marked as trusted. Run `/trust` and restart the session if needed. Skills
+    under `~/.gemini/skills/` (user scope) are not affected by trust.
+2.  **Check the path layout.** `SKILL.md` is discovered either at the root of
+    the skills directory (`.gemini/skills/SKILL.md`) or one directory deep
+    (`.gemini/skills/<skill-name>/SKILL.md`). The recommended layout uses a
+    subdirectory per skill so you can bundle scripts and other resources
+    alongside it. Files nested more than one directory deep are not discovered.
+3.  **The filename must be exactly `SKILL.md`.** Capitalization matters on
+    case-sensitive filesystems (Linux, and macOS when configured as such):
+    `skill.md` or `Skill.md` will be ignored.
+4.  **Frontmatter must include both `name:` and `description:`, and must be the
+    first thing in the file.** A `SKILL.md` is silently skipped if either field
+    is missing, if the delimiters (`---` on their own lines) are absent, or if
+    any text (an H1 title, a comment, even a blank line) appears before the
+    opening `---`.
+5.  **The skill name comes from the `name:` field, not the directory name.** If
+    your frontmatter says `name: foo`, the skill appears as `foo` in
+    `/skills list` regardless of what its parent directory is called. The
+    characters `: \ / < > * ? " |` in the name are replaced with `-`.
 
 ## How to use the skill
 
-Now, try it out. Start a new session and ask a question that triggers the
-skill's description.
+Now that the skill is discovered, you can trigger its activation by asking a
+relevant question.
 
-**User:** "Can you audit http://geminicli.com"
+1.  **Trigger**: Start a new session and ask: "Can you audit https://google.com"
+2.  **Activation**: Gemini identifies that the request matches the `api-auditor`
+    description and calls the `activate_skill` tool.
+3.  **Consent**: You will see a confirmation prompt. Type **y** to approve.
+4.  **Execution**: Once activated, Gemini uses the `run_shell_command` tool to
+    execute your bundled script:
+    `node .gemini/skills/api-auditor/scripts/audit.js https://google.com`
 
-Gemini recognizes the request matches the `api-auditor` description and asks for
-permission to activate it.
+## Pro tip: Use the skill-creator
 
-**Model:** (After calling `activate_skill`) "I've activated the **api-auditor**
-skill. I'll run the audit script now..."
+If you don't want to create the files manually, you can use the built-in
+`skill-creator` skill. Simply ask Gemini:
 
-Gemini then uses the `run_shell_command` tool to execute your bundled Node
-script:
+> "Create a new skill called 'api-auditor' that tests if URLs are responding."
 
-`node .gemini/skills/api-auditor/scripts/audit.js http://geminili.com`
+The `skill-creator` will handle the directory structure and boilerplate for you.
+
+## Manage skills
+
+You can also manage skills using the `gemini skills` command from your terminal:
+
+- **Install**: `gemini skills install <url-or-path>`
+- **Link**: `gemini skills link <path>` (useful for local development)
+- **Uninstall**: `gemini skills uninstall <name>`

+# Managing Agent Skills
+
+Agent Skills provide Gemini CLI with specialized expertise on demand. This guide
+covers advanced management techniques, including using slash commands, terminal
+utilities, and understanding discovery tiers.
+
+## Discovery tiers
+
+Gemini CLI discovers skills from several locations, following a specific order
+of precedence (lowest to highest):
+
+1.  **Built-in Skills**: Included with Gemini CLI and always available.
+2.  **Extension Skills**: Bundled within [extensions](../extensions/index.md).
+3.  **User Skills**: Located in `~/.gemini/skills/` or the `~/.agents/skills/`
+    alias. These are available across all your projects.
+4.  **Workspace Skills**: Located in `.gemini/skills/` or the `.agents/skills/`
+    alias within your current directory. These are project-specific.
+
+> **Tip:** If multiple skills share the same name, the version from the
+> higher-precedence location is used.
+
+## In-session management
+
+Use the `/skills` slash command during an interactive session to manage your
+available expertise.
+
+- **List skills**: `/skills list` (shows discovered skills).
+  - Use `/skills list all` to include internal built-in skills.
+  - Use `/skills list nodesc` to hide descriptions.
+- **Reload skills**: `/skills reload` (or `/skills refresh`) to scan for new or
+  modified skills without restarting the CLI.
+- **Toggle status**:
+  - `/skills disable <name>`: Prevents a skill from being triggered.
+  - `/skills enable <name>`: Re-enables a disabled skill.
+- **Link local skills**: `/skills link <path> [--scope user|workspace]` to
+  immediately use a skill you are developing.
+
+## Terminal utilities
+
+The `gemini skills` command provides management utilities directly from your
+system shell.
+
+### Install a skill
+
+To install a skill from a remote repository or a local `.skill` package:
+
+```bash
+gemini skills install https://github.com/user/my-awesome-skill
+```
+
+By default, this installs to your **user profile**. Use `--scope workspace` to
+install it only for the current project.
+
+### Link for development
+
+If you are developing a skill, use the `link` command to create a reference to
+your local directory:
+
+```bash
+gemini skills link ./path/to/my-skill
+```
+
+### Uninstall a skill
+
+To completely remove an installed or linked skill:
+
+```bash
+gemini skills uninstall <name>
+```
+
+## Security and consent
+
+Agent Skills can execute scripts and access your files. To protect your
+environment:
+
+1.  **Installation consent**: When installing from a remote URL, you will be
+    asked to confirm the source.
+2.  **Activation consent**: Every time a skill is triggered during a session,
+    the agent must ask for permission to activate it and gain access to its
+    resources.

+# `gemini gemma` — Automated Local Model Routing Setup
+
+Local model routing uses a local Gemma 3 1B model running on your machine to
+classify and route user requests. It routes simple requests (like file reads) to
+Gemini Flash and complex requests (like architecture discussions) to Gemini Pro.
+
+<!-- prettier-ignore -->
+> [!NOTE]
+> This is an experimental feature currently under active development.
+
+## What is this?
+
+This feature saves cloud API costs by using local inference for task
+classification instead of a cloud-based classifier. It adds a few milliseconds
+of local latency but can significantly reduce the overall token usage for hosted
+models.
+
+## Quick start
+
+```bash
+# One command does everything: downloads runtime, pulls model, configures settings, starts server
+gemini gemma setup
+```
+
+You'll be prompted to accept the Gemma Terms of Use. The model is ~1 GB.
+
+After setup, **just use the CLI normally** — routing happens automatically on
+every request.
+
+## Commands
+
+| Command               | What it does                                                   |
+| --------------------- | -------------------------------------------------------------- |
+| `gemini gemma setup`  | Full install (binary + model + settings + server start)        |
+| `gemini gemma status` | Health check — shows what's installed and running              |
+| `gemini gemma start`  | Start the LiteRT server (auto-starts on CLI launch by default) |
+| `gemini gemma stop`   | Stop the LiteRT server                                         |
+| `gemini gemma logs`   | Tail the server logs to see routing requests live              |
+| `/gemma`              | In-session status check (type it inside the CLI)               |
+
+## Verifying it works
+
+1. Run `gemini gemma status` — all checks should show green
+2. Open two terminals:
+   - Terminal 1: `gemini gemma logs` (watch for incoming requests)
+   - Terminal 2: use the CLI normally
+3. You should see classification requests appear in the logs as you interact
+   with the CLI
+4. The `/gemma` slash command inside a session shows a quick status panel
+
+## Setup flags
+
+```bash
+gemini gemma setup --port 8080      # custom port
+gemini gemma setup --no-start       # don't start server after install
+gemini gemma setup --force           # re-download everything
+gemini gemma setup --skip-model     # binary only, skip the 1GB model download
+```
+
+## How it works under the hood
+
+- Local Gemma classifies each request as "simple" or "complex" (~100ms)
+- Simple → Flash, Complex → Pro
+- If the local server is down, the CLI silently falls back to the cloud
+  classifier — no errors, no disruption
+
+## Disabling
+
+Set `enabled: false` in settings or just run `gemini gemma stop` to turn off the
+server:
+
+```json
+{ "experimental": { "gemmaModelRouter": { "enabled": false } } }
+```
+
+## Advanced setup
+
+If you are in an environment where the `gemini gemma setup` command cannot
+automatically download binaries (for example, behind a strict corporate
+firewall), you can perform the setup manually.
+
+For more information, see the
+[Manual Local Model Routing Setup guide](./local-model-routing.md).

+For example, to write a policy rule that blocks any `write_file` call targeting
+a `.env` file, you would match against the `file_path` key:
+
+```toml
+[[rule]]
+toolName = "write_file"
+argsPattern = '"file_path":".*\.env"'
+decision = "deny"
+priority = 100
+denyMessage = "Writing to .env files is not allowed."
+```

+in the [tables above](#available-tools).

+### Policy engine shorthands
+
+The [policy engine](../reference/policy-engine.md) provides two convenience
+fields for writing rules that target shell commands:
+
+- `commandPrefix`: Matches if the `command` argument starts with a given string.
+- `commandRegex`: Matches if the `command` argument matches a given regular
+  expression.
+
+These are syntactic sugar for combining `toolName = "run_shell_command"` with an
+`argsPattern` in a policy TOML file. They are **not** arguments of
+`run_shell_command` itself.

+# Agent Client Protocol (ACP) Implementation
+
+This directory contains the implementation of the Agent Client Protocol (ACP)
+for the Gemini CLI. The ACP allows external clients (like IDE extensions) to
+communicate with the Gemini CLI agent over a structured JSON-RPC based protocol.
+
+## Directory Structure
+
+Following Phase 1 of the modularization refactor, the ACP client is organized
+into the following specialized modules, all sharing the `acp` prefix for
+consistency:
+
+- **[acpStdioTransport.ts](./acpStdioTransport.ts)**: Handles raw I/O. It sets
+  up the Web streams for standard input/output and creates the
+  `AgentSideConnection` using line-delimited JSON (ndjson).
+- **[acpRpcDispatcher.ts](./acpRpcDispatcher.ts)**: Contains the `GeminiAgent`
+  class. This is the main entry point for incoming JSON-RPC messages. It
+  implements the protocol methods and delegates session-specific work to the
+  manager and individual sessions.
+- **[acpSessionManager.ts](./acpSessionManager.ts)**: Manages multi-session
+  state. It handles session creation (`newSession`), loading (`loadSession`),
+  and configuration, isolating session state from the RPC routing.
+- **[acpSession.ts](./acpSession.ts)**: Manages individual active chat sessions.
+  It handles prompt execution, `@path` file resolution, tool execution, command
+  interception, and streaming updates back to the client.
+- **[acpUtils.ts](./acpUtils.ts)**: Contains shared helper functions, type
+  mappers (e.g., mapping internal tool kinds to ACP kinds), and Zod schemas used
+  across the modules.
+- **[acpErrors.ts](./acpErrors.ts)**: Centralized error handling and mapping to
+  ACP-compliant error codes.
+- **[acpCommandHandler.ts](./acpCommandHandler.ts)**: Handles interception and
+  execution of slash commands (e.g., `/memory`, `/init`) sent via ACP prompts.
+- **[acpFileSystemService.ts](./acpFileSystemService.ts)**: Provides access to
+  the file system restricted by the workspace boundaries and permissions.
+
+## Development Instructions
+
+### Running Tests
+
+Tests are co-located with the source files:
+
+- `acpRpcDispatcher.test.ts`: Tests for initialization, authentication, and
+  handler delegation.
+- `acpSessionManager.test.ts`: Tests for session lifecycle and configuration.
+- `acpSession.test.ts`: Tests for prompt loops, tool execution, and @path
+  resolution.
+- `acpResume.test.ts`: Integration tests for loading/resuming sessions.
+
+To run specific tests, use Vitest with the workspace filter:
+
+```bash
+# General pattern
+npm test -w @google/gemini-cli -- src/acp/<test-file-name>.ts
+
+# Example
+npm test -w @google/gemini-cli -- src/acp/acpRpcDispatcher.test.ts
+```
+
+Note: You may need to ensure your environment has Node available. If running in
+a restricted environment, try sourcing NVM first:
+
+```bash
+source ~/.nvm/nvm.sh && nvm use default && npm test -w @google/gemini-cli -- src/acp/acpSession.test.ts
+```
+
+### Adding New Features
+
+- **New RPC Method**: Add the method to `GeminiAgent` in `acpRpcDispatcher.ts`
+  and register it in the `AgentSideConnection` setup if necessary.
+- **Session State**: If a feature requires storing state across turns within a
+  session, add it to the `Session` class in `acpSession.ts`.
+- **Protocol Helpers**: Add any new mapping or serialization logic to
+  `acpUtils.ts`.
+
+### Coding Conventions
+
+- **Imports**: Use specific imports and do not import across package boundaries
+  using relative paths.
+- **License Headers**: All new files must include the Apache-2.0 license header.
+- **Type Safety**: Avoid using `any` assertions. Use Zod schemas to validate
+  untrusted input from the protocol.
