feat: add getSystemPrompt method to mode interface (#400)

Allows modes to provide custom system prompts that are appended to Claude's base system prompt. This enables mode-specific instructions without modifying the core action logic.

- Add optional getSystemPrompt method to Mode interface
- Implement method in all existing modes (tag, agent, review)
- Update prepare.ts to call getSystemPrompt and export as env var
- Wire up APPEND_SYSTEM_PROMPT in action.yml to pass to base-action

All modes currently return undefined (no additional prompts), but the infrastructure is now in place for future modes to provide custom instructions.

 ## Architecture Overview
 
-This is a GitHub Action that enables Claude to interact with GitHub PRs and issues. The action:
+This is a GitHub Action that enables Claude to interact with GitHub PRs and issues. The action operates in two main phases:
 
-1. **Trigger Detection**: Uses `check-trigger.ts` to determine if Claude should respond based on comment/issue content
-2. **Context Gathering**: Fetches GitHub data (PRs, issues, comments) via `github-data-fetcher.ts` and formats it using `github-data-formatter.ts`
-3. **AI Integration**: Supports multiple Claude providers (Anthropic API, AWS Bedrock, Google Vertex AI)
-4. **Prompt Creation**: Generates context-rich prompts using `create-prompt.ts`
-5. **MCP Server Integration**: Installs and configures GitHub MCP server for extended functionality
+### Phase 1: Preparation (`src/entrypoints/prepare.ts`)
 
-### Key Components
+1. **Authentication Setup**: Establishes GitHub token via OIDC or GitHub App
+2. **Permission Validation**: Verifies actor has write permissions
+3. **Trigger Detection**: Uses mode-specific logic to determine if Claude should respond
+4. **Context Creation**: Prepares GitHub context and initial tracking comment
 
-- **Trigger System**: Responds to `/claude` comments or issue assignments
-- **Authentication**: OIDC-based token exchange for secure GitHub interactions
-- **Cloud Integration**: Supports direct Anthropic API, AWS Bedrock, and Google Vertex AI
-- **GitHub Operations**: Creates branches, posts comments, and manages PRs/issues
+### Phase 2: Execution (`base-action/`)
+
+The `base-action/` directory contains the core Claude Code execution logic, which serves a dual purpose:
+
+- **Standalone Action**: Published separately as `@anthropic-ai/claude-code-base-action` for direct use
+- **Inner Logic**: Used internally by this GitHub Action after preparation phase completes
+
+Execution steps:
+
+1. **MCP Server Setup**: Installs and configures GitHub MCP server for tool access
+2. **Prompt Generation**: Creates context-rich prompts from GitHub data
+3. **Claude Integration**: Executes via multiple providers (Anthropic API, AWS Bedrock, Google Vertex AI)
+4. **Result Processing**: Updates comments and creates branches/PRs as needed
+
+### Key Architectural Components
+
+#### Mode System (`src/modes/`)

-## Important Notes
+## Important Implementation Notes
 
-- Actions are triggered by `@claude` comments or issue assignment unless a different trigger_phrase is specified
-- The action creates branches for issues and pushes to PR branches directly
-- All actions create OIDC tokens for secure authentication
-- Progress is tracked through dynamic comment updates with checkboxes
+### Authentication Flow
+
+- Uses GitHub OIDC token exchange for secure authentication
+- Supports custom GitHub Apps via `APP_ID` and `APP_PRIVATE_KEY`
+- Falls back to official Claude GitHub App if no custom app provided
+
+### MCP Server Architecture
+
+- Each MCP server has specific GitHub API access patterns
+- Servers are auto-installed in `~/.claude/mcp/github-{type}-server/`
+- Configuration merged with user-provided MCP config via `mcp_config` input
+
+### Mode System Design
+
+- Modes implement `Mode` interface with `shouldTrigger()` and `prepare()` methods
+- Registry validates mode compatibility with GitHub event types
+- Agent mode only works with workflow_dispatch and schedule events
+
+### Comment Threading
+
+- Single tracking comment updated throughout execution
+- Progress indicated via dynamic checkboxes
+- Links to job runs and created branches/PRs
+- Sticky comment option for consolidated PR comments
+
+## Code Conventions
+
+- Use Bun-specific TypeScript configuration with `moduleResolution: "bundler"`
+- Strict TypeScript with `noUnusedLocals` and `noUnusedParameters` enabled
+- Prefer explicit error handling with detailed error messages
+- Use discriminated unions for GitHub context types
+- Implement retry logic for GitHub API operations via `utils/retry.ts`

+- This quickstart method is only available for direct Anthropic API users. For AWS Bedrock or Google Vertex AI setup, see [docs/cloud-providers.md](./docs/cloud-providers.md).
 
-### Manual Setup (Direct API)
+## Documentation
 
-**Requirements**: You must be a repository admin to complete these steps.
-
-1. Install the Claude GitHub app to your repository: https://github.com/apps/claude
-2. Add authentication to your repository secrets ([Learn how to use secrets in GitHub Actions](https://docs.github.com/en/actions/security-for-github-actions/security-guides/using-secrets-in-github-actions)):
-   - Either `ANTHROPIC_API_KEY` for API key authentication
-   - Or `CLAUDE_CODE_OAUTH_TOKEN` for OAuth token authentication (Pro and Max users can generate this by running `claude setup-token` locally)
-3. Copy the workflow file from [`examples/claude.yml`](./examples/claude.yml) into your repository's `.github/workflows/`
-
-### Using a Custom GitHub App
-
-If you prefer not to install the official Claude app, you can create your own GitHub App to use with this action. This gives you complete control over permissions and access.
-
-**When you may want to use a custom GitHub App:**
-
-- You need more restrictive permissions than the official app
-- Organization policies prevent installing third-party apps
-- You're using AWS Bedrock or Google Vertex AI
-
-**Steps to create and use a custom GitHub App:**
-
-1. **Create a new GitHub App:**
-
-   - Go to https://github.com/settings/apps (for personal apps) or your organization's settings
-   - Click "New GitHub App"
-   - Configure the app with these minimum permissions:
-     - **Repository permissions:**
-       - Contents: Read & Write
-       - Issues: Read & Write
-       - Pull requests: Read & Write
-     - **Account permissions:** None required
-   - Set "Where can this GitHub App be installed?" to your preference
-   - Create the app
-
-2. **Generate and download a private key:**
-
-   - After creating the app, scroll down to "Private keys"
-   - Click "Generate a private key"
-   - Download the `.pem` file (keep this secure!)
-
-3. **Install the app on your repository:**
-
-   - Go to the app's settings page
-   - Click "Install App"
-   - Select the repositories where you want to use Claude
-
-4. **Add the app credentials to your repository secrets:**
-
-   - Go to your repository's Settings → Secrets and variables → Actions
-   - Add these secrets:
-     - `APP_ID`: Your GitHub App's ID (found in the app settings)
-     - `APP_PRIVATE_KEY`: The contents of the downloaded `.pem` file
-
-5. **Update your workflow to use the custom app:**
-
-   ```yaml
-   name: Claude with Custom App
-   on:
-     issue_comment:
-       types: [created]
-     # ... other triggers
-
-   jobs:
-     claude-response:
-       runs-on: ubuntu-latest
-       steps:
-         # Generate a token from your custom app
-         - name: Generate GitHub App token
-           id: app-token
-           uses: actions/create-github-app-token@v1
-           with:
-             app-id: ${{ secrets.APP_ID }}
-             private-key: ${{ secrets.APP_PRIVATE_KEY }}
-
-         # Use Claude with your custom app's token
-         - uses: anthropics/claude-code-action@beta
-           with:
-             anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-             github_token: ${{ steps.app-token.outputs.token }}
-             # ... other configuration
-   ```
-
-**Important notes:**
-
-- The custom app must have read/write permissions for Issues, Pull Requests, and Contents
-- Your app's token will have the exact permissions you configured, nothing more

-\*Required when using direct Anthropic API (default and when not using Bedrock or Vertex)
-
-> **Note**: This action is currently in beta. Features and APIs may change as we continue to improve the integration.
-
-### Using Custom MCP Configuration
-
-The `mcp_config` input allows you to add custom MCP (Model Context Protocol) servers to extend Claude's capabilities. These servers merge with the built-in GitHub MCP servers.
-
-#### Basic Example: Adding a Sequential Thinking Server
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    mcp_config: |
-      {
-        "mcpServers": {
-          "sequential-thinking": {
-            "command": "npx",
-            "args": [
-              "-y",
-              "@modelcontextprotocol/server-sequential-thinking"
-            ]
-          }
-        }
-      }
-    allowed_tools: "mcp__sequential-thinking__sequentialthinking" # Important: Each MCP tool from your server must be listed here, comma-separated
-    # ... other inputs
-```
-
-#### Passing Secrets to MCP Servers
-
-For MCP servers that require sensitive information like API keys or tokens, use GitHub Secrets in the environment variables:
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    mcp_config: |
-      {
-        "mcpServers": {
-          "custom-api-server": {
-            "command": "npx",
-            "args": ["-y", "@example/api-server"],
-            "env": {
-              "API_KEY": "${{ secrets.CUSTOM_API_KEY }}",
-              "BASE_URL": "https://api.example.com"
-            }
-          }
-        }
-      }
-    # ... other inputs
-```
-
-#### Using Python MCP Servers with uv
-
-For Python-based MCP servers managed with `uv`, you need to specify the directory containing your server:
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    mcp_config: |
-      {
-        "mcpServers": {
-          "my-python-server": {
-            "type": "stdio",
-            "command": "uv",
-            "args": [
-              "--directory",
-              "${{ github.workspace }}/path/to/server/",
-              "run",
-              "server_file.py"
-            ]
-          }
-        }
-      }
-    allowed_tools: "my-python-server__<tool_name>" # Replace <tool_name> with your server's tool names
-    # ... other inputs
-```
-
-For example, if your Python MCP server is at `mcp_servers/weather.py`, you would use:
-
-```yaml
-"args":
-  ["--directory", "${{ github.workspace }}/mcp_servers/", "run", "weather.py"]
-```
-
-**Important**:
-
-- Always use GitHub Secrets (`${{ secrets.SECRET_NAME }}`) for sensitive values like API keys, tokens, or passwords. Never hardcode secrets directly in the workflow file.
-- Your custom servers will override any built-in servers with the same name.
-
-## Examples
-
-### Ways to Tag @claude
-
-These examples show how to interact with Claude using comments in PRs and issues. By default, Claude will be triggered anytime you mention `@claude`, but you can customize the exact trigger phrase using the `trigger_phrase` input in the workflow.
-
-Claude will see the full PR context, including any comments.
-
-#### Ask Questions
-
-Add a comment to a PR or issue:
-
-```
-@claude What does this function do and how could we improve it?
-```
-
-Claude will analyze the code and provide a detailed explanation with suggestions.
-
-#### Request Fixes
-
-Ask Claude to implement specific changes:
-
-```
-@claude Can you add error handling to this function?
-```
-
-#### Code Review
-
-Get a thorough review:
-
-```
-@claude Please review this PR and suggest improvements
-```
-
-Claude will analyze the changes and provide feedback.
-
-#### Fix Bugs from Screenshots
-
-Upload a screenshot of a bug and ask Claude to fix it:
-
-```
-@claude Here's a screenshot of a bug I'm seeing [upload screenshot]. Can you fix it?
-```
-
-Claude can see and analyze images, making it easy to fix visual bugs or UI issues.
-
-### Custom Automations

-When API files are modified, Claude automatically updates your README with the latest endpoint documentation and pushes the changes back to the PR, keeping your docs in sync with your code.
-
-#### Author-Specific Code Reviews
-
-Automatically review PRs from specific authors or external contributors (see [`examples/claude-review-from-author.yml`](./examples/claude-review-from-author.yml)):
-
-```yaml
-on:
-  pull_request:
-    types: [opened, synchronize]
-
-jobs:
-  review-by-author:
-    if: |
-      github.event.pull_request.user.login == 'developer1' ||
-      github.event.pull_request.user.login == 'external-contributor'
-    steps:
-      - uses: anthropics/claude-code-action@beta
-        with:
-          direct_prompt: |
-            Please provide a thorough review of this pull request.
-            Pay extra attention to coding standards, security practices,
-            and test coverage since this is from an external contributor.
-```
-
-Perfect for automatically reviewing PRs from new team members, external contributors, or specific developers who need extra guidance.
-
-## How It Works
-
-1. **Trigger Detection**: Listens for comments containing the trigger phrase (default: `@claude`) or issue assignment to a specific user
-2. **Context Gathering**: Analyzes the PR/issue, comments, code changes
-3. **Smart Responses**: Either answers questions or implements changes
-4. **Branch Management**: Creates new PRs for human authors, pushes directly for Claude's own PRs
-5. **Communication**: Posts updates at every step to keep you informed
-
-This action is built on top of [`anthropics/claude-code-base-action`](https://github.com/anthropics/claude-code-base-action).
-
-## Capabilities and Limitations
-
-### What Claude Can Do
-
-- **Respond in a Single Comment**: Claude operates by updating a single initial comment with progress and results
-- **Answer Questions**: Analyze code and provide explanations
-- **Implement Code Changes**: Make simple to moderate code changes based on requests
-- **Prepare Pull Requests**: Creates commits on a branch and links back to a prefilled PR creation page
-- **Perform Code Reviews**: Analyze PR changes and provide detailed feedback
-- **Smart Branch Handling**:
-  - When triggered on an **issue**: Always creates a new branch for the work
-  - When triggered on an **open PR**: Always pushes directly to the existing PR branch
-  - When triggered on a **closed PR**: Creates a new branch since the original is no longer active
-- **View GitHub Actions Results**: Can access workflow runs, job logs, and test results on the PR where it's tagged when `actions: read` permission is configured (see [Additional Permissions for CI/CD Integration](#additional-permissions-for-cicd-integration))
-
-### What Claude Cannot Do
-
-- **Submit PR Reviews**: Claude cannot submit formal GitHub PR reviews
-- **Approve PRs**: For security reasons, Claude cannot approve pull requests
-- **Post Multiple Comments**: Claude only acts by updating its initial comment
-- **Execute Commands Outside Its Context**: Claude only has access to the repository and PR/issue context it's triggered in
-- **Run Arbitrary Bash Commands**: By default, Claude cannot execute Bash commands unless explicitly allowed using the `allowed_tools` configuration
-- **Perform Branch Operations**: Cannot merge branches, rebase, or perform other git operations beyond pushing commits
-
-## Advanced Configuration
-
-### Additional Permissions for CI/CD Integration
-
-The `additional_permissions` input allows Claude to access GitHub Actions workflow information when you grant the necessary permissions. This is particularly useful for analyzing CI/CD failures and debugging workflow issues.
-
-#### Enabling GitHub Actions Access
-
-To allow Claude to view workflow run results, job logs, and CI status:
-
-1. **Grant the necessary permission to your GitHub token**:
-
-   - When using the default `GITHUB_TOKEN`, add the `actions: read` permission to your workflow:
-
-   ```yaml
-   permissions:
-     contents: write
-     pull-requests: write
-     issues: write
-     actions: read # Add this line
-   ```
-
-2. **Configure the action with additional permissions**:
-
-   ```yaml
-   - uses: anthropics/claude-code-action@beta
-     with:
-       anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-       additional_permissions: |
-         actions: read
-       # ... other inputs
-   ```
-
-3. **Claude will automatically get access to CI/CD tools**:
-   When you enable `actions: read`, Claude can use the following MCP tools:
-   - `mcp__github_ci__get_ci_status` - View workflow run statuses
-   - `mcp__github_ci__get_workflow_run_details` - Get detailed workflow information
-   - `mcp__github_ci__download_job_log` - Download and analyze job logs
-
-#### Example: Debugging Failed CI Runs
-
-```yaml
-name: Claude CI Helper
-on:
-  issue_comment:
-    types: [created]
-
-permissions:
-  contents: write
-  pull-requests: write
-  issues: write
-  actions: read # Required for CI access
-
-jobs:
-  claude-ci-helper:
-    runs-on: ubuntu-latest
-    steps:
-      - uses: anthropics/claude-code-action@beta
-        with:
-          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-          additional_permissions: |
-            actions: read
-          # Now Claude can respond to "@claude why did the CI fail?"
-```
-
-**Important Notes**:
-
-- The GitHub token must have the `actions: read` permission in your workflow
-- If the permission is missing, Claude will warn you and suggest adding it
-- Currently, only `actions: read` is supported, but the format allows for future extensions
-
-### Custom Environment Variables
-
-You can pass custom environment variables to Claude Code execution using the `claude_env` input. This is useful for CI/test setups that require specific environment variables:
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    claude_env: |
-      NODE_ENV: test
-      CI: true
-      DATABASE_URL: postgres://test:test@localhost:5432/test_db
-    # ... other inputs
-```
-
-The `claude_env` input accepts YAML format where each line defines a key-value pair. These environment variables will be available to Claude Code during execution, allowing it to run tests, build processes, or other commands that depend on specific environment configurations.
-
-### Limiting Conversation Turns
-
-You can use the `max_turns` parameter to limit the number of back-and-forth exchanges Claude can have during task execution. This is useful for:
-
-- Controlling costs by preventing runaway conversations
-- Setting time boundaries for automated workflows
-- Ensuring predictable behavior in CI/CD pipelines
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    max_turns: "5" # Limit to 5 conversation turns
-    # ... other inputs
-```
-
-When the turn limit is reached, Claude will stop execution gracefully. Choose a value that gives Claude enough turns to complete typical tasks while preventing excessive usage.
-
-### Custom Tools
-
-By default, Claude only has access to:
-
-- File operations (reading, committing, editing files, read-only git commands)
-- Comment management (creating/updating comments)
-- Basic GitHub operations
-
-Claude does **not** have access to execute arbitrary Bash commands by default. If you want Claude to run specific commands (e.g., npm install, npm test), you must explicitly allow them using the `allowed_tools` configuration:
-
-**Note**: If your repository has a `.mcp.json` file in the root directory, Claude will automatically detect and use the MCP server tools defined there. However, these tools still need to be explicitly allowed via the `allowed_tools` configuration.
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    allowed_tools: |
-      Bash(npm install)
-      Bash(npm run test)
-      Edit
-      Replace
-      NotebookEditCell
-    disallowed_tools: |
-      TaskOutput
-      KillTask
-    # ... other inputs
-```
-
-**Note**: The base GitHub tools are always included. Use `allowed_tools` to add additional tools (including specific Bash commands), and `disallowed_tools` to prevent specific tools from being used.
-
-### Custom Model
-
-Use a specific Claude model:
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    # model: "claude-3-5-sonnet-20241022"  # Optional: specify a different model
-    # ... other inputs
-```
-
-### Claude Code Settings
-
-You can provide Claude Code settings to customize behavior such as model selection, environment variables, permissions, and hooks. Settings can be provided either as a JSON string or a path to a settings file.
-
-#### Option 1: Settings File
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    settings: "path/to/settings.json"
-    # ... other inputs
-```
-
-#### Option 2: Inline Settings
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    settings: |
-      {
-        "model": "claude-opus-4-20250514",
-        "env": {
-          "DEBUG": "true",
-          "API_URL": "https://api.example.com"
-        },
-        "permissions": {
-          "allow": ["Bash", "Read"],
-          "deny": ["WebFetch"]
-        },
-        "hooks": {
-          "PreToolUse": [{
-            "matcher": "Bash",
-            "hooks": [{
-              "type": "command",
-              "command": "echo Running bash command..."
-            }]
-          }]
-        }
-      }
-    # ... other inputs
-```
-
-The settings support all Claude Code settings options including:
-
-- `model`: Override the default model
-- `env`: Environment variables for the session
-- `permissions`: Tool usage permissions
-- `hooks`: Pre/post tool execution hooks
-- And more...
-
-For a complete list of available settings and their descriptions, see the [Claude Code settings documentation](https://docs.anthropic.com/en/docs/claude-code/settings).
-
-**Notes**:
-
-- The `enableAllProjectMcpServers` setting is always set to `true` by this action to ensure MCP servers work correctly.
-- If both the `model` input parameter and a `model` in settings are provided, the `model` input parameter takes precedence.
-- The `allowed_tools` and `disallowed_tools` input parameters take precedence over `permissions` in settings.
-- In a future version, we may deprecate individual input parameters in favor of using the settings file for all configuration.
-
-## Cloud Providers
-
-You can authenticate with Claude using any of these three methods:
-
-1. Direct Anthropic API (default)
-2. Amazon Bedrock with OIDC authentication
-3. Google Vertex AI with OIDC authentication
-
-For detailed setup instructions for AWS Bedrock and Google Vertex AI, see the [official documentation](https://docs.anthropic.com/en/docs/claude-code/github-actions#using-with-aws-bedrock-%26-google-vertex-ai).
-
-**Note**:
-
-- Bedrock and Vertex use OIDC authentication exclusively
-- AWS Bedrock automatically uses cross-region inference profiles for certain models
-- For cross-region inference profile models, you need to request and be granted access to the Claude models in all regions that the inference profile uses
-
-### Model Configuration
-
-Use provider-specific model names based on your chosen provider:
-
-```yaml
-# For direct Anthropic API (default)
-- uses: anthropics/claude-code-action@beta
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    # ... other inputs
-
-# For Amazon Bedrock with OIDC
-- uses: anthropics/claude-code-action@beta
-  with:
-    model: "anthropic.claude-3-7-sonnet-20250219-beta:0" # Cross-region inference
-    use_bedrock: "true"
-    # ... other inputs
-
-# For Google Vertex AI with OIDC
-- uses: anthropics/claude-code-action@beta
-  with:
-    model: "claude-3-7-sonnet@20250219"
-    use_vertex: "true"
-    # ... other inputs
-```
-
-### OIDC Authentication for Bedrock and Vertex
-
-Both AWS Bedrock and GCP Vertex AI require OIDC authentication.
-
-```yaml
-# For AWS Bedrock with OIDC
-- name: Configure AWS Credentials (OIDC)
-  uses: aws-actions/configure-aws-credentials@v4
-  with:
-    role-to-assume: ${{ secrets.AWS_ROLE_TO_ASSUME }}
-    aws-region: us-west-2
-
-- name: Generate GitHub App token
-  id: app-token
-  uses: actions/create-github-app-token@v2
-  with:
-    app-id: ${{ secrets.APP_ID }}
-    private-key: ${{ secrets.APP_PRIVATE_KEY }}
-
-- uses: anthropics/claude-code-action@beta
-  with:
-    model: "anthropic.claude-3-7-sonnet-20250219-beta:0"
-    use_bedrock: "true"
-    # ... other inputs
-
-  permissions:
-    id-token: write # Required for OIDC
-```
-
-```yaml
-# For GCP Vertex AI with OIDC
-- name: Authenticate to Google Cloud
-  uses: google-github-actions/auth@v2
-  with:
-    workload_identity_provider: ${{ secrets.GCP_WORKLOAD_IDENTITY_PROVIDER }}
-    service_account: ${{ secrets.GCP_SERVICE_ACCOUNT }}
-
-- name: Generate GitHub App token
-  id: app-token
-  uses: actions/create-github-app-token@v2
-  with:
-    app-id: ${{ secrets.APP_ID }}
-    private-key: ${{ secrets.APP_PRIVATE_KEY }}
-
-- uses: anthropics/claude-code-action@beta
-  with:
-    model: "claude-3-7-sonnet@20250219"
-    use_vertex: "true"
-    # ... other inputs
-
-  permissions:
-    id-token: write # Required for OIDC
-```
-
-## Security
-
-### Access Control
-
-- **Repository Access**: The action can only be triggered by users with write access to the repository
-- **No Bot Triggers**: GitHub Apps and bots cannot trigger this action
-- **Token Permissions**: The GitHub app receives only a short-lived token scoped specifically to the repository it's operating in
-- **No Cross-Repository Access**: Each action invocation is limited to the repository where it was triggered
-- **Limited Scope**: The token cannot access other repositories or perform actions beyond the configured permissions
-
-### GitHub App Permissions
-
-The [Claude Code GitHub app](https://github.com/apps/claude) requires these permissions:
-
-- **Pull Requests**: Read and write to create PRs and push changes
-- **Issues**: Read and write to respond to issues
-- **Contents**: Read and write to modify repository files
-
-### Commit Signing
-
-All commits made by Claude through this action are automatically signed with commit signatures. This ensures the authenticity and integrity of commits, providing a verifiable trail of changes made by the action.
-
-### ⚠️ Authentication Protection
-
-**CRITICAL: Never hardcode your Anthropic API key or OAuth token in workflow files!**
-
-Your authentication credentials must always be stored in GitHub secrets to prevent unauthorized access:
-
-```yaml
-# CORRECT ✅
-anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-# OR
-claude_code_oauth_token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}
-
-# NEVER DO THIS ❌
-anthropic_api_key: "sk-ant-api03-..." # Exposed and vulnerable!
-claude_code_oauth_token: "oauth_token_..." # Exposed and vulnerable!
-```
-
-### Setting Up GitHub Secrets
-
-1. Go to your repository's Settings
-2. Click on "Secrets and variables" → "Actions"
-3. Click "New repository secret"
-4. For authentication, choose one:
-   - API Key: Name: `ANTHROPIC_API_KEY`, Value: Your Anthropic API key (starting with `sk-ant-`)
-   - OAuth Token: Name: `CLAUDE_CODE_OAUTH_TOKEN`, Value: Your Claude Code OAuth token (Pro and Max users can generate this by running `claude setup-token` locally)
-5. Click "Add secret"
-
-### Best Practices for Authentication
-
-1. ✅ Always use `${{ secrets.ANTHROPIC_API_KEY }}` or `${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}` in workflows
-2. ✅ Never commit API keys or tokens to version control
-3. ✅ Regularly rotate your API keys and tokens
-4. ✅ Use environment secrets for organization-wide access
-5. ❌ Never share API keys or tokens in pull requests or issues
-6. ❌ Avoid logging workflow variables that might contain keys
-
-## Security Best Practices
-
-**⚠️ IMPORTANT: Never commit API keys directly to your repository! Always use GitHub Actions secrets.**
-
-To securely use your Anthropic API key:
-
-1. Add your API key as a repository secret:
-
-   - Go to your repository's Settings
-   - Navigate to "Secrets and variables" → "Actions"
-   - Click "New repository secret"
-   - Name it `ANTHROPIC_API_KEY`
-   - Paste your API key as the value
-
-2. Reference the secret in your workflow:
-   ```yaml
-   anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-   ```
-
-**Never do this:**
-
-```yaml
-# ❌ WRONG - Exposes your API key
-anthropic_api_key: "sk-ant-..."
-```
-
-**Always do this:**
-
-```yaml
-# ✅ CORRECT - Uses GitHub secrets
-anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-```
-
-This applies to all sensitive values including API keys, access tokens, and credentials.
-We also recommend that you always use short-lived tokens when possible

+
+## Common Commands
+
+### Development Commands
+
+- Build/Type check: `bun run typecheck`
+- Format code: `bun run format`
+- Check formatting: `bun run format:check`
+- Run tests: `bun test`
+- Install dependencies: `bun install`
+
+### Action Testing
+
+- Test action locally: `./test-local.sh`
+- Test specific file: `bun test test/prepare-prompt.test.ts`
+
+## Architecture Overview
+
+This is a GitHub Action that allows running Claude Code within GitHub workflows. The action consists of:
+
+### Core Components
+
+1. **Action Definition** (`action.yml`): Defines inputs, outputs, and the composite action steps
+2. **Prompt Preparation** (`src/index.ts`): Runs Claude Code with specified arguments
+
+### Key Design Patterns
+
+- Uses Bun runtime for development and execution
+- Named pipes for IPC between prompt input and Claude process
+- JSON streaming output format for execution logs
+- Composite action pattern to orchestrate multiple steps
+- Provider-agnostic design supporting Anthropic API, AWS Bedrock, and Google Vertex AI
+
+## Provider Authentication
+
+1. **Anthropic API** (default): Requires API key via `anthropic_api_key` input
+2. **AWS Bedrock**: Uses OIDC authentication when `use_bedrock: true`
+3. **Google Vertex AI**: Uses OIDC authentication when `use_vertex: true`
+
+## Testing Strategy
+
+### Local Testing
+
+- Use `act` tool to run GitHub Actions workflows locally
+- `test-local.sh` script automates local testing setup
+- Requires `ANTHROPIC_API_KEY` environment variable
+
+### Test Structure
+
+- Unit tests for configuration logic
+- Integration tests for prompt preparation
+- Full workflow tests in `.github/workflows/test-action.yml`
+
+## Important Technical Details
+
+- Uses `mkfifo` to create named pipes for prompt input
+- Outputs execution logs as JSON to `/tmp/claude-execution-output.json`
+- Timeout enforcement via `timeout` command wrapper
+- Strict TypeScript configuration with Bun-specific settings

+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+claude-code-action-coc@anthropic.com.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.

+# Contributing to Claude Code Base Action
+
+Thank you for your interest in contributing to Claude Code Base Action! This document provides guidelines and instructions for contributing to the project.
+
+## Getting Started
+
+### Prerequisites
+
+- [Bun](https://bun.sh/) runtime
+- [Docker](https://www.docker.com/) (for running GitHub Actions locally)
+- [act](https://github.com/nektos/act) (installed automatically by our test script)
+- An Anthropic API key (for testing)
+
+### Setup
+
+1. Fork the repository on GitHub and clone your fork:
+
+   ```bash
+   git clone https://github.com/your-username/claude-code-base-action.git
+   cd claude-code-base-action
+   ```
+
+2. Install dependencies:
+
+   ```bash
+   bun install
+   ```
+
+3. Set up your Anthropic API key:
+   ```bash
+   export ANTHROPIC_API_KEY="your-api-key-here"
+   ```
+
+## Development
+
+### Available Scripts
+
+- `bun test` - Run all tests
+- `bun run typecheck` - Type check the code
+- `bun run format` - Format code with Prettier
+- `bun run format:check` - Check code formatting
+
+## Testing
+
+### Running Tests Locally
+
+1. **Unit Tests**:
+
+   ```bash
+   bun test
+   ```
+
+2. **Integration Tests** (using GitHub Actions locally):
+
+   ```bash
+   ./test-local.sh
+   ```
+
+   This script:
+
+   - Installs `act` if not present (requires Homebrew on macOS)
+   - Runs the GitHub Action workflow locally using Docker
+   - Requires your `ANTHROPIC_API_KEY` to be set
+
+   On Apple Silicon Macs, the script automatically adds the `--container-architecture linux/amd64` flag to avoid compatibility issues.
+
+## Pull Request Process
+
+1. Create a new branch from `main`:
+
+   ```bash
+   git checkout -b feature/your-feature-name
+   ```
+
+2. Make your changes and commit them:
+
+   ```bash
+   git add .
+   git commit -m "feat: add new feature"
+   ```
+
+3. Run tests and formatting:
+
+   ```bash
+   bun test
+   bun run typecheck
+   bun run format:check
+   ```
+
+4. Push your branch and create a Pull Request:
+
+   ```bash
+   git push origin feature/your-feature-name
+   ```
+
+5. Ensure all CI checks pass
+
+6. Request review from maintainers
+
+## Action Development
+
+### Testing Your Changes
+
+When modifying the action:
+
+1. Test locally with the test script:
+
+   ```bash
+   ./test-local.sh
+   ```
+
+2. Test in a real GitHub Actions workflow by:
+   - Creating a test repository
+   - Using your branch as the action source:
+     ```yaml
+     uses: your-username/claude-code-base-action@your-branch
+     ```
+
+### Debugging
+
+- Use `console.log` for debugging in development
+- Check GitHub Actions logs for runtime issues
+- Use `act` with `-v` flag for verbose output:
+  ```bash
+  act push -v --secret ANTHROPIC_API_KEY="$ANTHROPIC_API_KEY"
+  ```
+
+## Common Issues
+
+### Docker Issues
+
+Make sure Docker is running before using `act`. You can check with:
+
+```bash
+docker ps
+```

+
+Example usage:
+
+```yaml
+- name: Run Claude Code with Node.js 20
+  uses: anthropics/claude-code-base-action@beta
+  env:
+    NODE_VERSION: "20.x"
+  with:
+    prompt: "Your prompt here"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+## Custom Environment Variables
+
+You can pass custom environment variables to Claude Code execution using the `claude_env` input. This allows Claude to access environment-specific configuration during its execution.
+
+The `claude_env` input accepts YAML multiline format with key-value pairs:
+
+```yaml
+- name: Deploy with custom environment
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Deploy the application to the staging environment"
+    claude_env: |
+      ENVIRONMENT: staging
+      API_BASE_URL: https://api-staging.example.com
+      DATABASE_URL: ${{ secrets.STAGING_DB_URL }}
+      DEBUG: true
+      LOG_LEVEL: debug
+    allowed_tools: "Bash(git:*),View,GlobTool,GrepTool,BatchTool"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+### Features:
+
+- **YAML Format**: Use standard YAML key-value syntax (`KEY: value`)
+- **Multiline Support**: Define multiple environment variables in a single input
+- **Comments**: Lines starting with `#` are ignored
+- **GitHub Secrets**: Can reference GitHub secrets using `${{ secrets.SECRET_NAME }}`
+- **Runtime Access**: Environment variables are available to Claude during execution
+
+### Example Use Cases:
+
+```yaml
+# Development configuration

+
+## Using Settings Configuration
+
+You can provide Claude Code settings configuration in two ways:
+
+### Option 1: Settings Configuration File
+
+Provide a path to a JSON file containing Claude Code settings:
+
+```yaml
+- name: Run Claude Code with settings file
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Your prompt here"
+    settings: "path/to/settings.json"
+    allowed_tools: "Bash(git:*),View,GlobTool,GrepTool,BatchTool"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+### Option 2: Inline Settings Configuration
+
+Provide the settings configuration directly as a JSON string:
+
+```yaml
+- name: Run Claude Code with inline settings
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Your prompt here"
+    settings: |
+      {
+        "model": "claude-opus-4-20250514",
+        "env": {
+          "DEBUG": "true",
+          "API_URL": "https://api.example.com"
+        },
+        "permissions": {
+          "allow": ["Bash", "Read"],
+          "deny": ["WebFetch"]
+        },
+        "hooks": {
+          "PreToolUse": [{
+            "matcher": "Bash",
+            "hooks": [{
+              "type": "command",
+              "command": "echo Running bash command..."
+            }]
+          }]
+        }
+      }
+    allowed_tools: "Bash(git:*),View,GlobTool,GrepTool,BatchTool"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+The settings file supports all Claude Code settings options including:
+
+- `model`: Override the default model
+- `env`: Environment variables for the session
+- `permissions`: Tool usage permissions
+- `hooks`: Pre/post tool execution hooks
+- `includeCoAuthoredBy`: Include co-authored-by in git commits
+- And more...
+
+**Note**: The `enableAllProjectMcpServers` setting is always set to `true` by this action to ensure MCP servers work correctly.
+
+## Using MCP Config
+
+You can provide MCP configuration in two ways:
+
+### Option 1: MCP Configuration File
+
+Provide a path to a JSON file containing MCP configuration:
+
+```yaml
+- name: Run Claude Code with MCP config file
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Your prompt here"
+    mcp_config: "path/to/mcp-config.json"
+    allowed_tools: "Bash(git:*),View,GlobTool,GrepTool,BatchTool"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+### Option 2: Inline MCP Configuration
+
+Provide the MCP configuration directly as a JSON string:
+
+```yaml
+- name: Run Claude Code with inline MCP config
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Your prompt here"
+    mcp_config: |
+      {
+        "mcpServers": {
+          "server-name": {
+            "command": "node",
+            "args": ["./server.js"],
+            "env": {
+              "API_KEY": "your-api-key"
+            }
+          }
+        }
+      }
+    allowed_tools: "Bash(git:*),View,GlobTool,GrepTool,BatchTool"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+The MCP config file should follow this format:
+
+```json
+{
+  "mcpServers": {
+    "server-name": {
+      "command": "node",
+      "args": ["./server.js"],
+      "env": {
+        "API_KEY": "your-api-key"
+      }
+    }
+  }
+}
+```
+
+You can combine MCP config with other inputs like allowed tools:
+
+```yaml
+# Using multiple inputs together
+- name: Run Claude Code with MCP and custom tools
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Access the custom MCP server and use its tools"
+    mcp_config: "mcp-config.json"
+    allowed_tools: "Bash(git:*),View,mcp__server-name__custom_tool"
+    timeout_minutes: "15"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+

+              });
+            }
+```
+
+Check out additional examples in [`./examples`](./examples).
+
+## Using Cloud Providers
+
+You can authenticate with Claude using any of these methods:
+
+1. Direct Anthropic API (default) - requires API key or OAuth token
+2. Amazon Bedrock - requires OIDC authentication and automatically uses cross-region inference profiles
+3. Google Vertex AI - requires OIDC authentication
+
+**Note**:
+
+- Bedrock and Vertex use OIDC authentication exclusively
+- AWS Bedrock automatically uses cross-region inference profiles for certain models
+- For cross-region inference profile models, you need to request and be granted access to the Claude models in all regions that the inference profile uses
+- The Bedrock API endpoint URL is automatically constructed using the AWS_REGION environment variable (e.g., `https://bedrock-runtime.us-west-2.amazonaws.com`)
+- You can override the Bedrock API endpoint URL by setting the `ANTHROPIC_BEDROCK_BASE_URL` environment variable
+
+### Model Configuration
+
+Use provider-specific model names based on your chosen provider:
+
+```yaml
+# For direct Anthropic API (default)
+- name: Run Claude Code with Anthropic API
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Your prompt here"
+    model: "claude-3-7-sonnet-20250219"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+
+# For Amazon Bedrock (requires OIDC authentication)
+- name: Configure AWS Credentials (OIDC)
+  uses: aws-actions/configure-aws-credentials@v4
+  with:
+    role-to-assume: ${{ secrets.AWS_ROLE_TO_ASSUME }}
+    aws-region: us-west-2
+
+- name: Run Claude Code with Bedrock
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Your prompt here"
+    model: "anthropic.claude-3-7-sonnet-20250219-v1:0"
+    use_bedrock: "true"
+
+# For Google Vertex AI (requires OIDC authentication)
+- name: Authenticate to Google Cloud
+  uses: google-github-actions/auth@v2
+  with:
+    workload_identity_provider: ${{ secrets.GCP_WORKLOAD_IDENTITY_PROVIDER }}
+    service_account: ${{ secrets.GCP_SERVICE_ACCOUNT }}
+
+- name: Run Claude Code with Vertex AI
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Your prompt here"
+    model: "claude-3-7-sonnet@20250219"
+    use_vertex: "true"
+```
+
+## Example: Using OIDC Authentication for AWS Bedrock
+
+This example shows how to use OIDC authentication with AWS Bedrock:
+
+```yaml
+- name: Configure AWS Credentials (OIDC)
+  uses: aws-actions/configure-aws-credentials@v4
+  with:
+    role-to-assume: ${{ secrets.AWS_ROLE_TO_ASSUME }}
+    aws-region: us-west-2
+
+- name: Run Claude Code with AWS OIDC
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Your prompt here"
+    use_bedrock: "true"
+    model: "anthropic.claude-3-7-sonnet-20250219-v1:0"
+    allowed_tools: "Bash(git:*),View,GlobTool,GrepTool,BatchTool"
+```
+
+## Example: Using OIDC Authentication for GCP Vertex AI
+
+This example shows how to use OIDC authentication with GCP Vertex AI:
+
+```yaml
+- name: Authenticate to Google Cloud
+  uses: google-github-actions/auth@v2
+  with:
+    workload_identity_provider: ${{ secrets.GCP_WORKLOAD_IDENTITY_PROVIDER }}
+    service_account: ${{ secrets.GCP_SERVICE_ACCOUNT }}
+
+- name: Run Claude Code with GCP OIDC
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Your prompt here"
+    use_vertex: "true"
+    model: "claude-3-7-sonnet@20250219"
+    allowed_tools: "Bash(git:*),View,GlobTool,GrepTool,BatchTool"
+```
+
+## Security Best Practices
+
+**⚠️ IMPORTANT: Never commit API keys directly to your repository! Always use GitHub Actions secrets.**
+
+To securely use your Anthropic API key:
+
+1. Add your API key as a repository secret:
+
+   - Go to your repository's Settings
+   - Navigate to "Secrets and variables" → "Actions"
+   - Click "New repository secret"
+   - Name it `ANTHROPIC_API_KEY`
+   - Paste your API key as the value
+
+2. Reference the secret in your workflow:
+   ```yaml
+   anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+   ```
+
+**Never do this:**
+
+```yaml
+# ❌ WRONG - Exposes your API key
+anthropic_api_key: "sk-ant-..."
+```
+
+**Always do this:**
+
+```yaml
+# ✅ CORRECT - Uses GitHub secrets
+anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+This applies to all sensitive values including API keys, access tokens, and credentials.
+We also recommend that you always use short-lived tokens when possible

+          You're an issue triage assistant for GitHub issues. Your task is to analyze the issue and select appropriate labels from the provided list.
+
+          IMPORTANT: Don't post any comments or messages to the issue. Your only action should be to apply labels.
+
+          Issue Information:
+          - REPO: ${GITHUB_REPOSITORY}
+          - ISSUE_NUMBER: ${{ github.event.issue.number }}
+
+          TASK OVERVIEW:
+
+          1. First, fetch the list of labels available in this repository by running: `gh label list`. Run exactly this command with nothing else.
+
+          2. Next, use the GitHub tools to get context about the issue:
+             - You have access to these tools:
+               - mcp__github__get_issue: Use this to retrieve the current issue's details including title, description, and existing labels
+               - mcp__github__get_issue_comments: Use this to read any discussion or additional context provided in the comments
+               - mcp__github__update_issue: Use this to apply labels to the issue (do not use this for commenting)
+               - mcp__github__search_issues: Use this to find similar issues that might provide context for proper categorization and to identify potential duplicate issues
+               - mcp__github__list_issues: Use this to understand patterns in how other issues are labeled
+             - Start by using mcp__github__get_issue to get the issue details
+
+          3. Analyze the issue content, considering:
+             - The issue title and description
+             - The type of issue (bug report, feature request, question, etc.)
+             - Technical areas mentioned
+             - Severity or priority indicators
+             - User impact
+             - Components affected
+
+          4. Select appropriate labels from the available labels list provided above:
+             - Choose labels that accurately reflect the issue's nature
+             - Be specific but comprehensive
+             - Select priority labels if you can determine urgency (high-priority, med-priority, or low-priority)
+             - Consider platform labels (android, ios) if applicable
+             - If you find similar issues using mcp__github__search_issues, consider using a "duplicate" label if appropriate. Only do so if the issue is a duplicate of another OPEN issue.
+
+          5. Apply the selected labels:
+             - Use mcp__github__update_issue to apply your selected labels
+             - DO NOT post any comments explaining your decision
+             - DO NOT communicate directly with users
+             - If no labels are clearly applicable, do not apply any labels
+
+          IMPORTANT GUIDELINES:
+          - Be thorough in your analysis
+          - Only select labels from the provided list above
+          - DO NOT post any comments to the issue
+          - Your ONLY action should be to apply labels using mcp__github__update_issue
+          - It's okay to not add any labels if none are clearly applicable

+# Capabilities and Limitations
+
+## What Claude Can Do
+
+- **Respond in a Single Comment**: Claude operates by updating a single initial comment with progress and results
+- **Answer Questions**: Analyze code and provide explanations
+- **Implement Code Changes**: Make simple to moderate code changes based on requests
+- **Prepare Pull Requests**: Creates commits on a branch and links back to a prefilled PR creation page
+- **Perform Code Reviews**: Analyze PR changes and provide detailed feedback
+- **Smart Branch Handling**:
+  - When triggered on an **issue**: Always creates a new branch for the work
+  - When triggered on an **open PR**: Always pushes directly to the existing PR branch
+  - When triggered on a **closed PR**: Creates a new branch since the original is no longer active
+- **View GitHub Actions Results**: Can access workflow runs, job logs, and test results on the PR where it's tagged when `actions: read` permission is configured (see [Additional Permissions for CI/CD Integration](./configuration.md#additional-permissions-for-cicd-integration))
+
+## What Claude Cannot Do
+
+- **Submit PR Reviews**: Claude cannot submit formal GitHub PR reviews
+- **Approve PRs**: For security reasons, Claude cannot approve pull requests
+- **Post Multiple Comments**: Claude only acts by updating its initial comment
+- **Execute Commands Outside Its Context**: Claude only has access to the repository and PR/issue context it's triggered in
+- **Run Arbitrary Bash Commands**: By default, Claude cannot execute Bash commands unless explicitly allowed using the `allowed_tools` configuration
+- **Perform Branch Operations**: Cannot merge branches, rebase, or perform other git operations beyond pushing commits
+
+## How It Works
+
+1. **Trigger Detection**: Listens for comments containing the trigger phrase (default: `@claude`) or issue assignment to a specific user
+2. **Context Gathering**: Analyzes the PR/issue, comments, code changes
+3. **Smart Responses**: Either answers questions or implements changes
+4. **Branch Management**: Creates new PRs for human authors, pushes directly for Claude's own PRs
+5. **Communication**: Posts updates at every step to keep you informed
+

+# Cloud Providers
+
+You can authenticate with Claude using any of these three methods:
+
+1. Direct Anthropic API (default)
+2. Amazon Bedrock with OIDC authentication
+3. Google Vertex AI with OIDC authentication
+
+For detailed setup instructions for AWS Bedrock and Google Vertex AI, see the [official documentation](https://docs.anthropic.com/en/docs/claude-code/github-actions#using-with-aws-bedrock-%26-google-vertex-ai).
+
+**Note**:
+
+- Bedrock and Vertex use OIDC authentication exclusively
+- AWS Bedrock automatically uses cross-region inference profiles for certain models
+- For cross-region inference profile models, you need to request and be granted access to the Claude models in all regions that the inference profile uses
+
+## Model Configuration
+
+Use provider-specific model names based on your chosen provider:
+
+```yaml
+# For direct Anthropic API (default)
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    # ... other inputs
+
+# For Amazon Bedrock with OIDC
+- uses: anthropics/claude-code-action@beta
+  with:
+    model: "anthropic.claude-3-7-sonnet-20250219-beta:0" # Cross-region inference

+    model: "claude-3-7-sonnet@20250219"
+    use_vertex: "true"
+    # ... other inputs
+```
+
+## OIDC Authentication for Bedrock and Vertex
+
+Both AWS Bedrock and GCP Vertex AI require OIDC authentication.
+
+```yaml
+# For AWS Bedrock with OIDC
+- name: Configure AWS Credentials (OIDC)
+  uses: aws-actions/configure-aws-credentials@v4

+              "-y",
+              "@modelcontextprotocol/server-sequential-thinking"
+            ]
+          }
+        }
+      }
+    allowed_tools: "mcp__sequential-thinking__sequentialthinking" # Important: Each MCP tool from your server must be listed here, comma-separated
+    # ... other inputs
+```
+
+### Passing Secrets to MCP Servers
+
+For MCP servers that require sensitive information like API keys or tokens, use GitHub Secrets in the environment variables:
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    mcp_config: |
+      {
+        "mcpServers": {
+          "custom-api-server": {
+            "command": "npx",
+            "args": ["-y", "@example/api-server"],
+            "env": {
+              "API_KEY": "${{ secrets.CUSTOM_API_KEY }}",
+              "BASE_URL": "https://api.example.com"
+            }
+          }
+        }
+      }
+    # ... other inputs
+```
+
+### Using Python MCP Servers with uv
+
+For Python-based MCP servers managed with `uv`, you need to specify the directory containing your server:
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    mcp_config: |
+      {
+        "mcpServers": {
+          "my-python-server": {
+            "type": "stdio",
+            "command": "uv",
+            "args": [
+              "--directory",
+              "${{ github.workspace }}/path/to/server/",
+              "run",
+              "server_file.py"
+            ]
+          }
+        }
+      }
+    allowed_tools: "my-python-server__<tool_name>" # Replace <tool_name> with your server's tool names
+    # ... other inputs
+```
+
+For example, if your Python MCP server is at `mcp_servers/weather.py`, you would use:
+
+```yaml
+"args":
+  ["--directory", "${{ github.workspace }}/mcp_servers/", "run", "weather.py"]
+```
+
+**Important**:
+
+- Always use GitHub Secrets (`${{ secrets.SECRET_NAME }}`) for sensitive values like API keys, tokens, or passwords. Never hardcode secrets directly in the workflow file.
+- Your custom servers will override any built-in servers with the same name.
+
+## Additional Permissions for CI/CD Integration
+
+The `additional_permissions` input allows Claude to access GitHub Actions workflow information when you grant the necessary permissions. This is particularly useful for analyzing CI/CD failures and debugging workflow issues.
+
+### Enabling GitHub Actions Access
+
+To allow Claude to view workflow run results, job logs, and CI status:
+
+1. **Grant the necessary permission to your GitHub token**:
+
+   - When using the default `GITHUB_TOKEN`, add the `actions: read` permission to your workflow:
+
+   ```yaml
+   permissions:
+     contents: write
+     pull-requests: write
+     issues: write
+     actions: read # Add this line
+   ```
+
+2. **Configure the action with additional permissions**:
+
+   ```yaml
+   - uses: anthropics/claude-code-action@beta
+     with:
+       anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+       additional_permissions: |
+         actions: read
+       # ... other inputs
+   ```
+
+3. **Claude will automatically get access to CI/CD tools**:
+   When you enable `actions: read`, Claude can use the following MCP tools:
+   - `mcp__github_ci__get_ci_status` - View workflow run statuses
+   - `mcp__github_ci__get_workflow_run_details` - Get detailed workflow information
+   - `mcp__github_ci__download_job_log` - Download and analyze job logs
+
+### Example: Debugging Failed CI Runs
+
+```yaml
+name: Claude CI Helper
+on:
+  issue_comment:
+    types: [created]
+
+permissions:
+  contents: write
+  pull-requests: write
+  issues: write
+  actions: read # Required for CI access
+
+jobs:
+  claude-ci-helper:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: anthropics/claude-code-action@beta
+        with:
+          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+          additional_permissions: |
+            actions: read
+          # Now Claude can respond to "@claude why did the CI fail?"
+```
+
+**Important Notes**:
+
+- The GitHub token must have the `actions: read` permission in your workflow
+- If the permission is missing, Claude will warn you and suggest adding it
+- Currently, only `actions: read` is supported, but the format allows for future extensions
+
+## Custom Environment Variables
+
+You can pass custom environment variables to Claude Code execution using the `claude_env` input. This is useful for CI/test setups that require specific environment variables:
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    claude_env: |
+      NODE_ENV: test
+      CI: true
+      DATABASE_URL: postgres://test:test@localhost:5432/test_db
+    # ... other inputs
+```
+
+The `claude_env` input accepts YAML format where each line defines a key-value pair. These environment variables will be available to Claude Code during execution, allowing it to run tests, build processes, or other commands that depend on specific environment configurations.
+
+## Limiting Conversation Turns
+
+You can use the `max_turns` parameter to limit the number of back-and-forth exchanges Claude can have during task execution. This is useful for:
+
+- Controlling costs by preventing runaway conversations
+- Setting time boundaries for automated workflows
+- Ensuring predictable behavior in CI/CD pipelines
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    max_turns: "5" # Limit to 5 conversation turns
+    # ... other inputs
+```
+
+When the turn limit is reached, Claude will stop execution gracefully. Choose a value that gives Claude enough turns to complete typical tasks while preventing excessive usage.
+
+## Custom Tools
+
+By default, Claude only has access to:
+
+- File operations (reading, committing, editing files, read-only git commands)
+- Comment management (creating/updating comments)
+- Basic GitHub operations
+
+Claude does **not** have access to execute arbitrary Bash commands by default. If you want Claude to run specific commands (e.g., npm install, npm test), you must explicitly allow them using the `allowed_tools` configuration:
+
+**Note**: If your repository has a `.mcp.json` file in the root directory, Claude will automatically detect and use the MCP server tools defined there. However, these tools still need to be explicitly allowed via the `allowed_tools` configuration.
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    allowed_tools: |
+      Bash(npm install)
+      Bash(npm run test)
+      Edit
+      Replace
+      NotebookEditCell
+    disallowed_tools: |
+      TaskOutput
+      KillTask
+    # ... other inputs
+```
+
+**Note**: The base GitHub tools are always included. Use `allowed_tools` to add additional tools (including specific Bash commands), and `disallowed_tools` to prevent specific tools from being used.
+
+## Custom Model
+
+Use a specific Claude model:
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    # model: "claude-3-5-sonnet-20241022"  # Optional: specify a different model
+    # ... other inputs
+```
+
+## Claude Code Settings
+
+You can provide Claude Code settings to customize behavior such as model selection, environment variables, permissions, and hooks. Settings can be provided either as a JSON string or a path to a settings file.
+
+### Option 1: Settings File
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    settings: "path/to/settings.json"
+    # ... other inputs
+```
+
+### Option 2: Inline Settings
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    settings: |
+      {
+        "model": "claude-opus-4-20250514",
+        "env": {
+          "DEBUG": "true",
+          "API_URL": "https://api.example.com"
+        },
+        "permissions": {
+          "allow": ["Bash", "Read"],
+          "deny": ["WebFetch"]
+        },
+        "hooks": {
+          "PreToolUse": [{
+            "matcher": "Bash",
+            "hooks": [{
+              "type": "command",
+              "command": "echo Running bash command..."
+            }]
+          }]
+        }
+      }
+    # ... other inputs
+```
+
+The settings support all Claude Code settings options including:
+
+- `model`: Override the default model
+- `env`: Environment variables for the session
+- `permissions`: Tool usage permissions
+- `hooks`: Pre/post tool execution hooks
+- And more...
+
+For a complete list of available settings and their descriptions, see the [Claude Code settings documentation](https://docs.anthropic.com/en/docs/claude-code/settings).
+
+**Notes**:
+
+- The `enableAllProjectMcpServers` setting is always set to `true` by this action to ensure MCP servers work correctly.
+- If both the `model` input parameter and a `model` in settings are provided, the `model` input parameter takes precedence.
+- The `allowed_tools` and `disallowed_tools` input parameters take precedence over `permissions` in settings.
+- In a future version, we may deprecate individual input parameters in favor of using the settings file for all configuration.

+# Custom Automations
+
+These examples show how to configure Claude to act automatically based on GitHub events, without requiring manual @mentions.
+
+## Supported GitHub Events
+
+This action supports the following GitHub events ([learn more GitHub event triggers](https://docs.github.com/en/actions/writing-workflows/choosing-when-your-workflow-runs/events-that-trigger-workflows)):
+
+- `pull_request` - When PRs are opened or synchronized
+- `issue_comment` - When comments are created on issues or PRs
+- `pull_request_comment` - When comments are made on PR diffs
+- `issues` - When issues are opened or assigned
+- `pull_request_review` - When PR reviews are submitted
+- `pull_request_review_comment` - When comments are made on PR reviews
+- `repository_dispatch` - Custom events triggered via API (coming soon)
+- `workflow_dispatch` - Manual workflow triggers (coming soon)
+
+## Automated Documentation Updates
+
+Automatically update documentation when specific files change (see [`examples/claude-pr-path-specific.yml`](../examples/claude-pr-path-specific.yml)):
+
+```yaml
+on:
+  pull_request:
+    paths:
+      - "src/api/**/*.ts"
+
+steps:
+  - uses: anthropics/claude-code-action@beta
+    with:
+      direct_prompt: |
+        Update the API documentation in README.md to reflect
+        the changes made to the API endpoints in this PR.
+```
+
+When API files are modified, Claude automatically updates your README with the latest endpoint documentation and pushes the changes back to the PR, keeping your docs in sync with your code.
+
+## Author-Specific Code Reviews
+
+Automatically review PRs from specific authors or external contributors (see [`examples/claude-review-from-author.yml`](../examples/claude-review-from-author.yml)):
+
+```yaml
+on:
+  pull_request:
+    types: [opened, synchronize]
+
+jobs:
+  review-by-author:
+    if: |
+      github.event.pull_request.user.login == 'developer1' ||
+      github.event.pull_request.user.login == 'external-contributor'
+    steps:
+      - uses: anthropics/claude-code-action@beta
+        with:
+          direct_prompt: |
+            Please provide a thorough review of this pull request.
+            Pay extra attention to coding standards, security practices,
+            and test coverage since this is from an external contributor.
+```
+
+Perfect for automatically reviewing PRs from new team members, external contributors, or specific developers who need extra guidance.
+
+## Custom Prompt Templates
+
+Use `override_prompt` for complete control over Claude's behavior with variable substitution:
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    override_prompt: |
+      Analyze PR #$PR_NUMBER in $REPOSITORY for security vulnerabilities.
+
+      Changed files:
+      $CHANGED_FILES
+
+      Focus on:
+      - SQL injection risks
+      - XSS vulnerabilities
+      - Authentication bypasses
+      - Exposed secrets or credentials
+
+      Provide severity ratings (Critical/High/Medium/Low) for any issues found.
+```
+
+The `override_prompt` feature supports these variables:
+
+- `$REPOSITORY`, `$PR_NUMBER`, `$ISSUE_NUMBER`
+- `$PR_TITLE`, `$ISSUE_TITLE`, `$PR_BODY`, `$ISSUE_BODY`
+- `$PR_COMMENTS`, `$ISSUE_COMMENTS`, `$REVIEW_COMMENTS`
+- `$CHANGED_FILES`, `$TRIGGER_COMMENT`, `$TRIGGER_USERNAME`
+- `$BRANCH_NAME`, `$BASE_BRANCH`, `$EVENT_TYPE`, `$IS_PR`

+# Experimental Features
+
+**Note:** Experimental features are considered unstable and not supported for production use. They may change or be removed at any time.
+
+## Execution Modes
+
+The action supports three execution modes, each optimized for different use cases:
+
+### Tag Mode (Default)
+
+The traditional implementation mode that responds to @claude mentions, issue assignments, or labels.
+
+- **Triggers**: `@claude` mentions, issue assignment, label application
+- **Features**: Creates tracking comments with progress checkboxes, full implementation capabilities
+- **Use case**: General-purpose code implementation and Q&A
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    # mode: tag is the default
+```
+
+### Agent Mode
+
+**Note: Agent mode is currently in active development and may undergo breaking changes.**
+
+For automation with workflow_dispatch and scheduled events only.
+
+- **Triggers**: Only works with `workflow_dispatch` and `schedule` events - does NOT work with PR/issue events
+- **Features**: Perfect for scheduled tasks, works with `override_prompt`
+- **Use case**: Maintenance tasks, automated reporting, scheduled checks
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: agent
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    override_prompt: |
+      Check for outdated dependencies and create an issue if any are found.
+```
+
+### Experimental Review Mode
+
+**Warning: This is an experimental feature that may change or be removed at any time.**
+
+For automated code reviews on pull requests.
+
+- **Triggers**: Pull request events (`opened`, `synchronize`) or `@claude review` comments
+- **Features**: Provides detailed code reviews with inline comments and suggestions
+- **Use case**: Automated PR reviews, code quality checks
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: experimental-review
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    custom_instructions: |
+      Focus on code quality, security, and best practices.
+```
+
+See [`examples/claude-modes.yml`](../examples/claude-modes.yml) and [`examples/claude-experimental-review-mode.yml`](../examples/claude-experimental-review-mode.yml) for complete examples of each mode.
+
+## Network Restrictions
+
+For enhanced security, you can restrict Claude's network access to specific domains only. This feature is particularly useful for:
+
+- Enterprise environments with strict security policies
+- Preventing access to external services
+- Limiting Claude to only your internal APIs and services
+
+When `experimental_allowed_domains` is set, Claude can only access the domains you explicitly list. You'll need to include the appropriate provider domains based on your authentication method.
+
+### Provider-Specific Examples
+
+#### If using Anthropic API or subscription
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    # Or: claude_code_oauth_token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}
+    experimental_allowed_domains: |
+      .anthropic.com
+```
+
+#### If using AWS Bedrock
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    use_bedrock: "true"
+    experimental_allowed_domains: |
+      bedrock.*.amazonaws.com
+      bedrock-runtime.*.amazonaws.com
+```
+
+#### If using Google Vertex AI
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    use_vertex: "true"
+    experimental_allowed_domains: |
+      *.googleapis.com
+      vertexai.googleapis.com
+```
+
+### Common GitHub Domains
+
+In addition to your provider domains, you may need to include GitHub-related domains. For GitHub.com users, common domains include:
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    experimental_allowed_domains: |
+      .anthropic.com  # For Anthropic API
+      .github.com
+      .githubusercontent.com
+      ghcr.io
+      .blob.core.windows.net
+```
+
+For GitHub Enterprise users, replace the GitHub.com domains above with your enterprise domains (e.g., `.github.company.com`, `packages.company.com`, etc.).
+
+To determine which domains your workflow needs, you can temporarily run without restrictions and monitor the network requests, or check your GitHub Enterprise configuration for the specific services you use.

 No, Claude's GitHub app token is sandboxed to the current repository only. It cannot push to any other repositories. It can, however, read public repositories, but to get access to this, you must configure it with tools to do so.
 
+### Why aren't comments posted as claude[bot]?
+
+Comments appear as claude[bot] when the action uses its built-in authentication. However, if you provide a `github_token` in your workflow, the action will use that token's authentication instead, causing comments to appear under a different username.
+
+**Solution**: Remove `github_token` from your workflow file unless you're using a custom GitHub App.
+
+**Note**: The `use_sticky_comment` feature only works with claude[bot] authentication. If you're using a custom `github_token`, sticky comments won't update properly since they expect the claude[bot] username.

+# Security
+
+## Access Control
+
+- **Repository Access**: The action can only be triggered by users with write access to the repository
+- **No Bot Triggers**: GitHub Apps and bots cannot trigger this action
+- **Token Permissions**: The GitHub app receives only a short-lived token scoped specifically to the repository it's operating in
+- **No Cross-Repository Access**: Each action invocation is limited to the repository where it was triggered
+- **Limited Scope**: The token cannot access other repositories or perform actions beyond the configured permissions
+
+## GitHub App Permissions
+
+The [Claude Code GitHub app](https://github.com/apps/claude) requires these permissions:
+
+- **Pull Requests**: Read and write to create PRs and push changes
+- **Issues**: Read and write to respond to issues
+- **Contents**: Read and write to modify repository files
+
+## Commit Signing
+
+All commits made by Claude through this action are automatically signed with commit signatures. This ensures the authenticity and integrity of commits, providing a verifiable trail of changes made by the action.
+
+## ⚠️ Authentication Protection
+
+**CRITICAL: Never hardcode your Anthropic API key or OAuth token in workflow files!**
+
+Your authentication credentials must always be stored in GitHub secrets to prevent unauthorized access:
+
+```yaml

+# Setup Guide
+
+## Manual Setup (Direct API)
+
+**Requirements**: You must be a repository admin to complete these steps.
+
+1. Install the Claude GitHub app to your repository: https://github.com/apps/claude
+2. Add authentication to your repository secrets ([Learn how to use secrets in GitHub Actions](https://docs.github.com/en/actions/security-for-github-actions/security-guides/using-secrets-in-github-actions)):
+   - Either `ANTHROPIC_API_KEY` for API key authentication
+   - Or `CLAUDE_CODE_OAUTH_TOKEN` for OAuth token authentication (Pro and Max users can generate this by running `claude setup-token` locally)
+3. Copy the workflow file from [`examples/claude.yml`](../examples/claude.yml) into your repository's `.github/workflows/`
+
+## Using a Custom GitHub App
+
+If you prefer not to install the official Claude app, you can create your own GitHub App to use with this action. This gives you complete control over permissions and access.
+
+**When you may want to use a custom GitHub App:**
+
+- You need more restrictive permissions than the official app
+- Organization policies prevent installing third-party apps
+- You're using AWS Bedrock or Google Vertex AI
+
+**Steps to create and use a custom GitHub App:**
+
+1. **Create a new GitHub App:**
+
+   - Go to https://github.com/settings/apps (for personal apps) or your organization's settings
+   - Click "New GitHub App"
+   - Configure the app with these minimum permissions:
+     - **Repository permissions:**
+       - Contents: Read & Write
+       - Issues: Read & Write
+       - Pull requests: Read & Write
+     - **Account permissions:** None required
+   - Set "Where can this GitHub App be installed?" to your preference
+   - Create the app
+
+2. **Generate and download a private key:**
+
+   - After creating the app, scroll down to "Private keys"
+   - Click "Generate a private key"
+   - Download the `.pem` file (keep this secure!)
+
+3. **Install the app on your repository:**
+
+   - Go to the app's settings page
+   - Click "Install App"
+   - Select the repositories where you want to use Claude
+
+4. **Add the app credentials to your repository secrets:**
+
+   - Go to your repository's Settings → Secrets and variables → Actions
+   - Add these secrets:
+     - `APP_ID`: Your GitHub App's ID (found in the app settings)
+     - `APP_PRIVATE_KEY`: The contents of the downloaded `.pem` file
+
+5. **Update your workflow to use the custom app:**
+
+   ```yaml
+   name: Claude with Custom App
+   on:
+     issue_comment:
+       types: [created]
+     # ... other triggers
+
+   jobs:
+     claude-response:
+       runs-on: ubuntu-latest
+       steps:
+         # Generate a token from your custom app
+         - name: Generate GitHub App token
+           id: app-token
+           uses: actions/create-github-app-token@v1
+           with:
+             app-id: ${{ secrets.APP_ID }}
+             private-key: ${{ secrets.APP_PRIVATE_KEY }}
+
+         # Use Claude with your custom app's token
+         - uses: anthropics/claude-code-action@beta
+           with:
+             anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+             github_token: ${{ steps.app-token.outputs.token }}
+             # ... other configuration
+   ```
+
+**Important notes:**
+
+- The custom app must have read/write permissions for Issues, Pull Requests, and Contents
+- Your app's token will have the exact permissions you configured, nothing more

+
+## Security Best Practices
+
+**⚠️ IMPORTANT: Never commit API keys directly to your repository! Always use GitHub Actions secrets.**
+
+To securely use your Anthropic API key:
+
+1. Add your API key as a repository secret:
+
+   - Go to your repository's Settings
+   - Navigate to "Secrets and variables" → "Actions"
+   - Click "New repository secret"
+   - Name it `ANTHROPIC_API_KEY`
+   - Paste your API key as the value
+
+2. Reference the secret in your workflow:
+   ```yaml
+   anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+   ```
+
+**Never do this:**
+
+```yaml
+# ❌ WRONG - Exposes your API key
+anthropic_api_key: "sk-ant-..."
+```
+
+**Always do this:**
+
+```yaml
+# ✅ CORRECT - Uses GitHub secrets
+anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+This applies to all sensitive values including API keys, access tokens, and credentials.
+We also recommend that you always use short-lived tokens when possible
+
+## Setting Up GitHub Secrets
+
+1. Go to your repository's Settings
+2. Click on "Secrets and variables" → "Actions"
+3. Click "New repository secret"
+4. For authentication, choose one:
+   - API Key: Name: `ANTHROPIC_API_KEY`, Value: Your Anthropic API key (starting with `sk-ant-`)
+   - OAuth Token: Name: `CLAUDE_CODE_OAUTH_TOKEN`, Value: Your Claude Code OAuth token (Pro and Max users can generate this by running `claude setup-token` locally)
+5. Click "Add secret"
+
+### Best Practices for Authentication
+
+1. ✅ Always use `${{ secrets.ANTHROPIC_API_KEY }}` or `${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}` in workflows
+2. ✅ Never commit API keys or tokens to version control
+3. ✅ Regularly rotate your API keys and tokens
+4. ✅ Use environment secrets for organization-wide access
+5. ❌ Never share API keys or tokens in pull requests or issues
+6. ❌ Avoid logging workflow variables that might contain keys

+    ? `<direct_prompt>
+${context.directPrompt}
+</direct_prompt>`
+    : ""
+}
+
+REVIEW MODE WORKFLOW:
+
+1. First, understand the PR context:
+   - You are reviewing PR #${eventData.isPR && eventData.prNumber ? eventData.prNumber : "[PR number]"} in ${context.repository}
+   - Use mcp__github__get_pull_request to get PR metadata
+   - Use the Read, Grep, and Glob tools to examine the modified files directly from disk
+   - This provides the full context and latest state of the code
+   - Look at the changed_files section above to see which files were modified
+
+2. Create a pending review:
+   - Use mcp__github__create_pending_pull_request_review to start your review
+   - This allows you to batch comments before submitting
+
+3. Add inline comments:
+   - Use mcp__github__add_comment_to_pending_review for each issue or suggestion
+   - Parameters:
+     * path: The file path (e.g., "src/index.js")
+     * line: Line number for single-line comments
+     * startLine & line: For multi-line comments (startLine is the first line, line is the last)
+     * side: "LEFT" (old code) or "RIGHT" (new code)
+     * subjectType: "line" for line-level comments
+     * body: Your comment text
+   
+   - When to use multi-line comments:
+     * When replacing multiple consecutive lines
+     * When the fix requires changes across several lines
+     * Example: To replace lines 19-20, use startLine: 19, line: 20
+   
+   - For code suggestions, use this EXACT format in the body:
+     \`\`\`suggestion
+     corrected code here
+     \`\`\`
+   
+   CRITICAL: GitHub suggestion blocks must ONLY contain the replacement for the specific line(s) being commented on:
+   - For single-line comments: Replace ONLY that line
+   - For multi-line comments: Replace ONLY the lines in the range
+   - Do NOT include surrounding context or function signatures
+   - Do NOT suggest changes that span beyond the commented lines
+   
+   Example for line 19 \`var name = user.name;\`:
+   WRONG:
+   \\\`\\\`\\\`suggestion
+   function processUser(user) {
+       if (!user) throw new Error('Invalid user');
+       const name = user.name;
+   \\\`\\\`\\\`
+   
+   CORRECT:
+   \\\`\\\`\\\`suggestion
+   const name = user.name;
+   \\\`\\\`\\\`
+   
+   For validation suggestions, comment on the function declaration line or create separate comments for each concern.
+
+4. Submit your review:
+   - Use mcp__github__submit_pending_pull_request_review
+   - Parameters:
+     * event: "COMMENT" (general feedback), "REQUEST_CHANGES" (issues found), or "APPROVE" (if appropriate)
+     * body: Write a comprehensive review summary that includes:
+       - Overview of what was reviewed (files, scope, focus areas)
+       - Summary of all issues found (with counts by severity if applicable)
+       - Key recommendations and action items
+       - Highlights of good practices observed
+       - Overall assessment and recommendation
+   - The body should be detailed and informative since it's the main review content
+   - Structure the body with clear sections using markdown headers
+
+REVIEW GUIDELINES:
+
+- Focus on:
+  * Security vulnerabilities
+  * Bugs and logic errors
+  * Performance issues
+  * Code quality and maintainability
+  * Best practices and standards
+  * Edge cases and error handling
+
+- Provide:
+  * Specific, actionable feedback
+  * Code suggestions when possible (following GitHub's format exactly)
+  * Clear explanations of issues
+  * Constructive criticism
+  * Recognition of good practices
+  * For complex changes that require multiple modifications:
+    - Create separate comments for each logical change
+    - Or explain the full solution in text without a suggestion block
+
+- Communication:
+  * All feedback goes through GitHub's review system
+  * Be professional and respectful
+  * Your review body is the main communication channel
+
+Before starting, analyze the PR inside <analysis> tags:
+<analysis>
+- PR title and description
+- Number of files changed and scope
+- Type of changes (feature, bug fix, refactor, etc.)
+- Key areas to focus on
+- Review strategy
+</analysis>
+
+Then proceed with the review workflow described above.
+
+IMPORTANT: Your review body is the primary way users will understand your feedback. Make it comprehensive and well-structured with:
+- Executive summary at the top
+- Detailed findings organized by severity or category
+- Clear action items and recommendations
+- Recognition of good practices
+This ensures users get value from the review even before checking individual inline comments.`;
