+
+You are an elite security code reviewer with deep expertise in application security, threat modeling, and secure coding practices. Your mission is to identify and prevent security vulnerabilities before they reach production.
+
+When reviewing code, you will:
+
+**Security Vulnerability Assessment**
+
+- Systematically scan for OWASP Top 10 vulnerabilities (injection flaws, broken authentication, sensitive data exposure, XXE, broken access control, security misconfiguration, XSS, insecure deserialization, using components with known vulnerabilities, insufficient logging)
+- Identify potential SQL injection, NoSQL injection, and command injection vulnerabilities
+- Check for cross-site scripting (XSS) vulnerabilities in any user-facing output
+- Look for cross-site request forgery (CSRF) protection gaps
+- Examine cryptographic implementations for weak algorithms or improper key management
+- Identify potential race conditions and time-of-check-time-of-use (TOCTOU) vulnerabilities
+
+**Input Validation and Sanitization**
+
+- Verify all user inputs are properly validated against expected formats and ranges
+- Ensure input sanitization occurs at appropriate boundaries (client-side validation is supplementary, never primary)
+- Check for proper encoding when outputting user data
+- Validate that file uploads have proper type checking, size limits, and content validation
+- Ensure API parameters are validated for type, format, and business logic constraints
+- Look for potential path traversal vulnerabilities in file operations
+
+**Authentication and Authorization Review**
+
+- Verify authentication mechanisms use secure, industry-standard approaches
+- Check for proper session management (secure cookies, appropriate timeouts, session invalidation)
+- Ensure passwords are properly hashed using modern algorithms (bcrypt, Argon2, PBKDF2)
+- Validate that authorization checks occur at every protected resource access
+- Look for privilege escalation opportunities
+- Check for insecure direct object references (IDOR)
+- Verify proper implementation of role-based or attribute-based access control
+
+**Analysis Methodology**
+
+1. First, identify the security context and attack surface of the code
+2. Map data flows from untrusted sources to sensitive operations
+3. Examine each security-critical operation for proper controls
+4. Consider both common vulnerabilities and context-specific threats
+5. Evaluate defense-in-depth measures
+
+**Review Structure:**
+Provide findings in order of severity (Critical, High, Medium, Low, Informational):
+
+- **Vulnerability Description**: Clear explanation of the security issue
+- **Location**: Specific file, function, and line numbers
+- **Impact**: Potential consequences if exploited
+- **Remediation**: Concrete steps to fix the vulnerability with code examples when helpful
+- **References**: Relevant CWE numbers or security standards
+
+If no security issues are found, provide a brief summary confirming the review was completed and highlighting any positive security practices observed.
+
+Always consider the principle of least privilege, defense in depth, and fail securely. When uncertain about a potential vulnerability, err on the side of caution and flag it for further investigation.

+description: Apply labels to GitHub issues
+---
+
+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: `./scripts/gh.sh label list`. Run exactly this command with nothing else.
+
+2. Next, use gh wrapper commands to get context about the issue:
+
+   - Use `./scripts/gh.sh issue view ${{ github.event.issue.number }}` to retrieve the current issue's details
+   - Use `./scripts/gh.sh search issues` to find similar issues that might provide context for proper categorization
+   - `./scripts/gh.sh` is a wrapper for `gh` CLI. Example commands:
+     - `./scripts/gh.sh label list` — fetch all available labels
+     - `./scripts/gh.sh issue view 123` — view issue details
+     - `./scripts/gh.sh issue view 123 --comments` — view with comments
+     - `./scripts/gh.sh search issues "query" --limit 10` — search for issues
+   - `./scripts/edit-issue-labels.sh` — apply labels to the issue
+
+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
+   - IMPORTANT: Add a priority label (P1, P2, or P3) based on the label descriptions from ./scripts/gh.sh label list
+   - Consider platform labels (android, ios) if applicable
+   - If you find similar issues using ./scripts/gh.sh search, 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 `./scripts/edit-issue-labels.sh --add-label LABEL1 --add-label LABEL2` to apply your selected labels (issue number is read from the workflow event)
+   - 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 ./scripts/edit-issue-labels.sh
+- It's okay to not add any labels if none are clearly applicable

+
+The full PR (metadata, body, existing reviews/comments, and complete diff) is in /tmp/claude/pr-sweep/${n}.md — read it first. The repo is checked out at the current working directory. Read the actual current source files the diff touches to verify the diff applies cleanly conceptually and the claims in the PR body are true. Do NOT modify anything or run git commands that change state.
+
+Context about this repo:
+- It's a GitHub Action that runs Claude on issues/PRs. It processes UNTRUSTED content (PR bodies, comments, branch names, file contents from forks). Treat any change touching content sanitization, actor/bot allowlists, config restoration, prompt construction, or shell command construction as high-risk.
+- Most candidate PRs are from EXTERNAL contributors. Treat the diff with suspicion: look for subtle malicious changes, weakened validation, injection vectors, overly broad permissions, or changes whose description doesn't match the code.
+- Runtime is Bun; strict TypeScript (noUnusedLocals/noUnusedParameters). Tests are unit tests run with bun test.
+
+Stamp criteria (ALL must hold):
+1. Small, focused, and the code does exactly what the title/body says.
+2. No major behavior change — bug fixes restoring intended behavior, docs fixes, test-only additions, and small niceties qualify. New inputs/features, behavior redesigns, or large refactors do NOT.
+3. Correct: you verified the logic against the actual current source, not just the diff. Check edge cases.
+4. No security concern. Check explicitly for: prompt injection (untrusted text reaching Claude's prompt without sanitization), code execution (untrusted data reaching shell commands, eval/spawn, or GitHub workflow expressions), path traversal (untrusted input influencing filesystem paths), credential exposure (tokens reaching logs, comments, or attacker-readable output), weakened validation or permission checks, and suspicious hunks unrelated to the stated purpose.
+5. Wouldn't break the public API of base-action/ or action.yml output wiring.
+
+If the PR is a docs change, verify the docs claims against the actual code behavior. If test-only, check tests actually pass conceptually (assert the right things, match real implementations) and don't weaken or skip anything.
+
+Verdicts: "stamp" = approve as-is; "needs-discussion" = plausible but has questions/issues worth a comment; "skip" = too big, wrong, redundant, or risky.
+
+If this PR appears to duplicate another open PR (same fix, same files), still judge it on its own merits but note the duplication in duplicateOf.

+Their assessment: ${JSON.stringify(review)}
+
+Read the full PR at /tmp/claude/pr-sweep/${n}.md and the touched source files in the current working directory. This repo processes untrusted PR/issue content from forks; anything that lets untrusted content reach Claude's prompt, a shell command, a workflow expression, or a filesystem path unsanitized is a critical vulnerability.
+
+Hunt specifically for:
+- Subtle malice or scope creep: hunks that don't match the stated purpose, weakened validation, regex changes that widen acceptance, removed escaping.
+- Prompt injection: untrusted data (comment bodies, branch names, file contents, command output, downloaded files) reaching Claude's prompt or context without sanitization, including indirect routes like tool output Claude later reads.
+- Code execution: untrusted data reaching shell commands, eval/spawn argv, GitHub workflow \${{ }} expressions, or API call templates; new process spawning; path traversal letting untrusted input write or read outside intended directories.
+- Credential exposure: tokens or secrets flowing into logs, posted comments, error messages, env passed to untrusted code, or files Claude can read.
+- Logic errors the first reviewer missed: off-by-one, wrong polarity, unhandled edge cases (empty strings, unicode, very long inputs).
+- Supply-chain angles: pinned versions that don't match the claimed SHA/tag, new dependencies, fetched URLs.
+- For docs PRs: claims that would mislead users into insecure configurations.
+- For test-only PRs: tests that codify wrong behavior, or that would mask future regressions.
+
+If the diff pins a version/SHA, verify the claim is plausible from local information; flag if unverifiable. Be strict: if uncertain whether something is a real problem, lean toward reporting it as a finding with your uncertainty noted. Only return safeToStamp=true if you genuinely failed to find any disqualifying issue.

-## Architecture Overview
+## What This Is
 
-This is a GitHub Action that enables Claude to interact with GitHub PRs and issues. The action:
+A GitHub Action that lets Claude respond to `@claude` mentions on issues/PRs (tag mode) or run tasks via `prompt` input (agent mode). Mode is auto-detected: if `prompt` is provided, it's agent mode; if triggered by a comment/issue event with `@claude`, it's tag mode. See `src/modes/detector.ts`.
 
-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
+## How It Runs
 
-### Key Components
+Single entrypoint: `src/entrypoints/run.ts` orchestrates everything — prepare (auth, permissions, trigger check, branch/comment creation), install Claude Code CLI, execute Claude via `base-action/` functions (imported directly, not subprocess), then cleanup (update tracking comment, write step summary). SSH signing cleanup and token revocation are separate `always()` steps in `action.yml`.
 
-- **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
+`base-action/` is also published standalone as `@anthropic-ai/claude-code-base-action`. Don't break its public API. It reads config from `INPUT_`-prefixed env vars (set by `action.yml`), not from action inputs directly.
 
-### Project Structure
+## Key Concepts
 
-```
-src/
-├── check-trigger.ts        # Determines if Claude should respond
-├── create-prompt.ts        # Generates contextual prompts
-├── github-data-fetcher.ts  # Retrieves GitHub data
-├── github-data-formatter.ts # Formats GitHub data for prompts
-├── install-mcp-server.ts  # Sets up GitHub MCP server
-├── update-comment-with-link.ts # Updates comments with job links
-└── types/
-    └── github.ts          # TypeScript types for GitHub data
-```
+**Auth priority**: `github_token` input (user-provided) > GitHub App OIDC token (default). The `claude_code_oauth_token` and `anthropic_api_key` are for the Claude API, not GitHub. Token setup lives in `src/github/token.ts`.
 
-## Important Notes
+**Mode lifecycle**: `detectMode()` in `src/modes/detector.ts` picks the mode name ("tag" or "agent"). Trigger checking and prepare dispatch are inlined in `run.ts`: tag mode calls `prepareTagMode()` from `src/modes/tag/`, agent mode calls `prepareAgentMode()` from `src/modes/agent/`.
 
-- 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
+**Prompt construction**: Tag mode's `prepareTagMode()` builds the prompt by fetching GitHub data (`src/github/data/fetcher.ts`), formatting it as markdown (`src/github/data/formatter.ts`), and writing it to a temp file via `createPrompt()`. Agent mode writes the user's prompt directly. The prompt includes issue/PR body, comments, diff, and CI status. This is the most important part of the action — it's what Claude sees.
+
+## Things That Will Bite You
+
+- **Strict TypeScript**: `noUnusedLocals` and `noUnusedParameters` are enabled. Typecheck will fail on unused variables.
+- **Discriminated unions for GitHub context**: `GitHubContext` is a union type — call `isEntityContext(context)` before accessing entity-specific fields like `context.issue` or `context.pullRequest`.
+- **Token lifecycle matters**: The GitHub App token is obtained early and revoked in a separate `always()` step in `action.yml`. If you move token revocation into `run.ts`, it won't run if the process crashes. Same for SSH signing cleanup.
+- **Error phase attribution**: The catch block in `run.ts` uses `prepareCompleted` to distinguish prepare failures from execution failures. The tracking comment shows different messages for each.
+- **`action.yml` outputs reference step IDs**: Outputs like `execution_file`, `branch_name`, `github_token` reference `steps.run.outputs.*`. If you rename the step ID, update the outputs section too.
+- **Integration testing** happens in a separate repo (`install-test`), not here. The tests in this repo are unit tests.
+
+## Code Conventions
+
+- Runtime is Bun, not Node. Use `bun test`, not `jest`.
+- `moduleResolution: "bundler"` — imports don't need `.js` extensions.
+- GitHub API calls should use retry logic (`src/utils/retry.ts`).
+- MCP servers are auto-installed at runtime to `~/.claude/mcp/github-{type}-server/`.

-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
-
-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.
-
-## 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
-
-### 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
-- **View CI/CD Results**: Cannot access CI systems, test results, or build logs unless an additional tool or MCP server is configured
-- **Perform Branch Operations**: Cannot merge branches, rebase, or perform other git operations beyond pushing commits
-
-## Advanced Configuration
-
-### 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
-```
-
-## 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.
-
-### ⚠️ ANTHROPIC_API_KEY Protection
-
-**CRITICAL: Never hardcode your Anthropic API key in workflow files!**
-
-Your ANTHROPIC_API_KEY must always be stored in GitHub secrets to prevent unauthorized access:
-
-```yaml
-# CORRECT ✅
-anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-
-# NEVER DO THIS ❌
-anthropic_api_key: "sk-ant-api03-..." # Exposed and vulnerable!
-```
-
-### Setting Up GitHub Secrets
-
-1. Go to your repository's Settings
-2. Click on "Secrets and variables" → "Actions"
-3. Click "New repository secret"
-4. Name: `ANTHROPIC_API_KEY`
-5. Value: Your Anthropic API key (starting with `sk-ant-`)
-6. Click "Add secret"
-
-### Best Practices for ANTHROPIC_API_KEY
-
-1. ✅ Always use `${{ secrets.ANTHROPIC_API_KEY }}` in workflows
-2. ✅ Never commit API keys to version control
-3. ✅ Regularly rotate your API keys
-4. ✅ Use environment secrets for organization-wide access
-5. ❌ Never share API keys 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 reccomend that you always use short-lived tokens when possible

+# Claude Code GitHub Action Roadmap
+
+Thank you for trying out the beta of our GitHub Action! This document outlines our path to `v1.0`. Items are not necessarily in priority order.
+
+## Path to 1.0
+
+- ~**Ability to see GitHub Action CI results** - This will enable Claude to look at CI failures and make updates to PRs to fix test failures, lint errors, and the like.~
+- **Cross-repo support** - Enable Claude to work across multiple repositories in a single session
+- **Ability to modify workflow files** - Let Claude update GitHub Actions workflows and other CI configuration files
+- **Support for workflow_dispatch and repository_dispatch events** - Dispatch Claude on events triggered via API from other workflows or from other services
+- **Ability to disable commit signing** - Option to turn off GPG signing for environments where it's not required. This will enable Claude to use normal `git` bash commands for committing. This will likely become the default behavior once added.
+- **Better code review behavior** - Support inline comments on specific lines, provide higher quality reviews with more actionable feedback
+- ~**Support triggering @claude from bot users** - Allow automation and bot accounts to invoke Claude~
+- **Customizable base prompts** - Full control over Claude's initial context with template variables like `$PR_COMMENTS`, `$PR_FILES`, etc. Users can replace our default prompt entirely while still accessing key contextual data
+
+---
+
+**Note:** This roadmap represents our current vision for reaching `v1.0` and is subject to change based on user feedback and development priorities.
+
+We welcome feedback on these planned features! If you're interested in contributing to any of these features, please open an issue to discuss implementation details with us. We're also open to suggestions for new features not listed here.

+# Agent Approval Check
+
+Require **N human approvals** on any pull request that contains commits
+authored by an AI agent (Claude, Claude Code, or any bot identity you
+configure). PRs without agent activity are unaffected.
+
+This is the same gate Anthropic runs internally on every agent-authored PR.
+
+## What it does
+
+When a PR is opened, pushed to, or commented on, this action:
+
+1. Scans the PR's commits, author, and reviews for the configured agent
+   identities (committer email, bot login, or an `APPROVED` review from a
+   bot). If none are found it posts `success: No agent activity` and stops.
+2. Counts distinct human approvals: the latest `APPROVED` review per login,
+   plus any `/approve <head-sha>` comment whose SHA matches the current
+   head. Only users with write access to the repo count (verified per-user
+   via the collaborators permission API); agent and excluded-bot logins
+   never count.
+3. Posts an `agent-approval-check` commit status (`success` once the count
+   reaches `required_approvals`, otherwise `pending`) and a sticky PR
+   comment explaining what's still needed.
+4. Re-evaluates on every new push or comment. A push moves the head SHA,
+   so earlier `/approve <old-sha>` comments are flagged stale. Approving
+   reviews still count toward the threshold — they're picked up the next
+   time the workflow runs (on push or `/approve`); they just don't trigger
+   a run on their own.
+
+Mark `agent-approval-check` as a **required status check** on your protected
+branches and GitHub will refuse to merge until it's green.
+
+## Setup
+
+Copy [`examples/agent-approval-check.yml`](../examples/agent-approval-check.yml)
+into `.github/workflows/` in your repo, then add `agent-approval-check` to the
+required status checks on your protected branch.
+
+This action is designed to run **alongside** GitHub's native branch
+protection, not replace it. On the same protected branch you should also:
+
+1. Require at least 1 approving review from someone with write access.
+2. Enable **Dismiss stale pull request approvals when new commits are pushed**.

+
+> ⚠️ **`config_file` and checkout:** if you set `config_file`, your workflow
+> must check out the **base** branch to read it (the default behaviour of
+> `actions/checkout` under `pull_request_target`). Never check out the PR
+> head ref — doing so would let the PR author control the config and bypass
+> this check.
+
+## Approving
+
+A human counts as an approver by either:
+
+- submitting a normal GitHub **Approve** review, or
+- commenting `/approve <sha>` where `<sha>` is the current head commit
+  (12–40 hex chars). This path lets the PR author — who can't approve their
+  own PR in GitHub's UI — vouch for commits an agent pushed on their behalf.
+  The author's `/approve` is subject to the same write-access verification
+  as any other approver, so a fork-PR author without write access on the
+  base repository cannot self-count. The author counts as **one** approval;
+  the remaining approvals must come from other reviewers with write access.
+
+## Threat model
+
+- **Tamper-proof triggers.** `pull_request_target` and `issue_comment` run
+  the workflow file from the base/default branch, so the PR under review
+  cannot edit this check. `pull_request_review` does **not** share this
+  property — it runs from the merge ref — so the example workflow omits it;
+  native Approve reviews are picked up on the next synchronize or
+  `/approve` comment. This tamper-resistance assumes the workflow file
+  itself is protected: an actor who can push workflow changes to the
+  default branch can spoof any required status check, including this one,
+  so protect `.github/workflows/` via branch protection or CODEOWNERS.
+- **Fail-closed.** Any unhandled error exits non-zero; the required status
+  stays non-success and the PR stays blocked. PRs with >100 commits are
+  treated as agent-authored because the full commit list can't be verified.
+- **Sibling-PR guard.** Commit statuses attach to a SHA, not a PR. The
+  action refuses to post a status on a PR whose base isn't in
+  `protected_bases`, and withholds `success` while another open PR to a
+  protected base shares the same head commit — otherwise a green status on
+  one PR would also unblock the other.
+- **No checkout of PR code.** The action never checks out the PR's branch;
+  it reads PR metadata via the GitHub API, so the usual
+  `pull_request_target` code-execution risk does not apply.

+## 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
+- 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-base-action.yml`
+
+## Important Technical Details
+
+- Outputs execution logs as JSON to `/tmp/claude-execution-output.json`
+- Timeout enforcement via `timeout` command wrapper
+- Strict TypeScript configuration with Bun-specific settings

+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience

+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.

+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.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

+# 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
+```

+# Claude Code Base Action
+
+This GitHub Action allows you to run [Claude Code](https://www.anthropic.com/claude-code) within your GitHub Actions workflows. You can use this to build any custom workflow on top of Claude Code.
+
+For simply tagging @claude in issues and PRs out of the box, [check out the Claude Code action and GitHub app](https://github.com/anthropics/claude-code-action).
+
+## Trust model
+
+This action is a thin wrapper that installs and runs Claude Code with the inputs you provide. It does **not** enforce any trust boundaries on its own. Running this action in a directory is equivalent to running Claude Code in that directory — Claude reads project-level configuration (`.claude/`, `CLAUDE.md`, `.mcp.json`, etc.) from the working directory, and the action's own setup steps run from there as well.
+
+**The caller is responsible for ensuring the working directory and prompt are trusted.** If your workflow processes untrusted input (issues, fork pull requests, external comments), use [`anthropics/claude-code-action`](https://github.com/anthropics/claude-code-action) instead — it provides actor permission checks, restores project configuration from the base ref in PR contexts, and is the supported path for those scenarios.
+
+See [Claude Code's security documentation](https://docs.anthropic.com/en/docs/claude-code/security) and the [GitHub Actions guidance on `pull_request_target`](https://securitylab.github.com/research/github-actions-preventing-pwn-requests/) for background.
+
+## Usage
+
+Add the following to your workflow file:
+
+```yaml
+# Using a direct prompt

+
+### Workload Identity Federation
+
+Instead of a static API key or OAuth token, you can authenticate via [Workload Identity Federation](https://platform.claude.com/docs/en/manage-claude/workload-identity-federation): the action fetches the workflow's GitHub OIDC token and the Claude Code CLI exchanges it for a short-lived access token. Requires the `id-token: write` permission on the job:
+
+```yaml
+permissions:
+  contents: read
+  id-token: write
+
+steps:
+  - name: Run Claude Code with workload identity federation
+    uses: anthropics/claude-code-base-action@beta
+    with:
+      prompt: "Your prompt here"
+      anthropic_federation_rule_id: fdrl_xxxxxxxxxxxx
+      anthropic_organization_id: 00000000-0000-0000-0000-000000000000
+      anthropic_service_account_id: svac_xxxxxxxxxxxx
+```
+
+Do not set `anthropic_api_key` or `claude_code_oauth_token` alongside the federation inputs — a static credential takes precedence and federation will not be used.

+
+## Environment Variables
+
+The following environment variables can be used to configure the action:
+
+| Variable       | Description                                           | Default |
+| -------------- | ----------------------------------------------------- | ------- |
+| `NODE_VERSION` | Node.js version to use (e.g., '18.x', '20.x', '22.x') | '18.x'  |
+
+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: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+## Custom Environment Variables
+
+You can pass custom environment variables to Claude Code through the `env` object in `settings`:
+
+```yaml
+- name: Deploy with custom environment
+  uses: anthropics/claude-code-base-action@beta
+  with:
+    prompt: "Deploy the application to the staging environment"
+    settings: |
+      {
+        "env": {
+          "ENVIRONMENT": "staging",
+          "API_BASE_URL": "https://api-staging.example.com",
+          "DATABASE_URL": "${{ secrets.STAGING_DB_URL }}",
+          "DEBUG": "true",
+          "LOG_LEVEL": "debug"
+        }
+      }
+    claude_args: '--allowedTools "Bash(git:*),Read,Glob,Grep"'
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+The `settings` input accepts either inline JSON or a path to a settings JSON file. Values in the `env` object are available during the Claude Code session and can reference GitHub secrets.
+
+## 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"
+    claude_args: '--allowedTools "Bash(git:*),Read,Glob,Grep"'
+    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-4-1-20250805",
+        "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..."
+            }]
+          }]
+        }
+      }
+    claude_args: '--allowedTools "Bash(git:*),Read,Glob,Grep"'
+    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"
+    claude_args: |
+      --mcp-config "path/to/mcp-config.json"
+      --allowedTools "Bash(git:*),Read,Glob,Grep"
+    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"
+    claude_args: >-
+      --mcp-config '{"mcpServers":{"server-name":{"command":"node","args":["./server.js"],"env":{"API_KEY":"your-api-key"}}}}'
+      --allowedTools "Bash(git:*),Read,Glob,Grep"
+    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"
+    claude_args: |
+      --mcp-config "mcp-config.json"
+      --allowedTools "Bash(git:*),Read,mcp__server-name__custom_tool"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+

+For typed automation output, prefer passing `--json-schema` in `claude_args`
+and reading `steps.<id>.outputs.structured_output` instead of parsing the full
+execution log.
+
+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"
+    claude_args: "--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"
+    claude_args: "--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"
+    claude_args: "--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"
+    claude_args: |
+      --model "anthropic.claude-3-7-sonnet-20250219-v1:0"
+      --allowedTools "Bash(git:*),Read,Glob,Grep"
+```
+
+## 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"
+    claude_args: |
+      --model "claude-3-7-sonnet@20250219"
+      --allowedTools "Bash(git:*),Read,Glob,Grep"
+```
+
+## 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 four methods:
+
+1. Direct Anthropic API (default)
+2. Amazon Bedrock with OIDC authentication
+3. Google Vertex AI with OIDC authentication
+4. Microsoft Foundry with OIDC authentication
+
+For detailed setup instructions for AWS Bedrock and Google Vertex AI, see the [official documentation](https://code.claude.com/docs/en/github-actions#using-with-amazon-bedrock-and-google-cloud).
+
+**Note**:
+
+- Bedrock, Vertex, and Microsoft Foundry 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

+# Advanced Configuration
+
+## Using Custom MCP Configuration
+
+You can add custom MCP (Model Context Protocol) servers to extend Claude's capabilities using the `--mcp-config` flag in `claude_args`. These servers merge with the built-in GitHub MCP servers.
+
+### Basic Example: Adding a Sequential Thinking Server
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --mcp-config '{"mcpServers": {"sequential-thinking": {"command": "npx", "args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]}}}'
+      --allowedTools mcp__sequential-thinking__sequentialthinking
+    # ... other inputs
+```
+
+### Passing Secrets to MCP Servers
+
+For MCP servers that require sensitive information like API keys or tokens, you can create a configuration file with GitHub Secrets:
+
+```yaml
+- name: Create MCP Config
+  run: |
+    cat > /tmp/mcp-config.json << 'EOF'
+    {
+      "mcpServers": {
+        "custom-api-server": {
+          "command": "npx",
+          "args": ["-y", "@example/api-server"],
+          "env": {
+            "API_KEY": "${{ secrets.CUSTOM_API_KEY }}",
+            "BASE_URL": "https://api.example.com"
+          }
+        }
+      }
+    }
+    EOF
+
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --mcp-config /tmp/mcp-config.json
+    # ... other inputs
+```
+
+### Using Python MCP Servers with uv
+
+For Python-based MCP servers managed with `uv`, you need to specify the directory containing your server:
+
+```yaml
+- name: Create MCP Config for Python Server
+  run: |
+    cat > /tmp/mcp-config.json << 'EOF'
+    {
+      "mcpServers": {
+        "my-python-server": {
+          "type": "stdio",
+          "command": "uv",
+          "args": [
+            "--directory",
+            "${{ github.workspace }}/path/to/server/",
+            "run",
+            "server_file.py"
+          ]
+        }
+      }
+    }
+    EOF
+
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --mcp-config /tmp/mcp-config.json
+      --allowedTools my-python-server__<tool_name>  # Replace <tool_name> with your server's tool names
+    # ... other inputs
+```
+
+For example, if your Python MCP server is at `mcp_servers/weather.py`, you would use:
+
+```yaml
+"args":
+  ["--directory", "${{ github.workspace }}/mcp_servers/", "run", "weather.py"]
+```
+
+### Multiple MCP Servers
+
+You can add multiple MCP servers by using multiple `--mcp-config` flags:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --mcp-config /tmp/config1.json
+      --mcp-config /tmp/config2.json
+      --mcp-config '{"mcpServers": {"inline-server": {"command": "npx", "args": ["@example/server"]}}}'
+    # ... other inputs
+```
+
+**Important**:
+
+- Always use GitHub Secrets (`${{ 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.
+- The `claude_args` supports multiple `--mcp-config` flags that will be merged together.
+
+## 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@v1
+     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@v1
+        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 corresponding permission in your workflow
+- If the permission is missing, Claude will warn you and suggest adding it
+- The following additional permissions can be requested beyond the defaults:
+  - `actions: read`
+  - `checks: read`
+  - `discussions: read` or `discussions: write`
+  - `workflows: read` or `workflows: write`
+- Standard permissions (`contents: write`, `pull_requests: write`, `issues: write`) are always included and do not need to be specified
+
+## Custom Environment Variables
+
+You can pass custom environment variables to Claude Code execution using the `settings` input. This is useful for CI/test setups that require specific environment variables:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    settings: |
+      {
+        "env": {
+          "NODE_ENV": "test",
+          "CI": "true",
+          "DATABASE_URL": "postgres://test:test@localhost:5432/test_db"
+        }
+      }
+    # ... other inputs
+```
+
+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 limit the number of back-and-forth exchanges Claude can have during task execution using the `claude_args` input. 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@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --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 `claude_args` 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.
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    claude_args: |
+      --allowedTools "Bash(npm install),Bash(npm run test),Edit,Replace,NotebookEditCell"
+      --disallowedTools "TaskOutput,KillTask"
+    # ... other inputs
+```
+
+**Note**: The base GitHub tools are always included. Use `--allowedTools` to add additional tools (including specific Bash commands), and `--disallowedTools` to prevent specific tools from being used.
+
+## Custom Model
+
+Specify a Claude model using `claude_args`:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    claude_args: |
+      --model claude-4-0-sonnet-20250805
+    # ... other inputs
+```
+
+For provider-specific models:
+
+```yaml
+# AWS Bedrock
+- uses: anthropics/claude-code-action@v1
+  with:
+    use_bedrock: "true"
+    claude_args: |
+      --model anthropic.claude-4-0-sonnet-20250805-v1:0
+    # ... other inputs
+
+# Google Vertex AI
+- uses: anthropics/claude-code-action@v1
+  with:
+    use_vertex: "true"
+    claude_args: |
+      --model claude-4-0-sonnet@20250805
+    # ... other inputs
+```
+
+### 1M context models through an API gateway
+
+When `ANTHROPIC_BASE_URL` points to an Anthropic-compatible API gateway,
+Claude Code may not be able to verify that the gateway supports a model's native
+1M context window and can budget the session at 200K instead. Append the
+`[1m]` selector to explicitly use the 1M context window for supported models,
+including Claude Opus 5 and Claude Sonnet 5:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    claude_args: |
+      --model "claude-opus-5[1m]"
+    # ... other inputs
+```
+
+Use the same selector when setting a model through `ANTHROPIC_MODEL` or another
+Claude Code model environment variable. The selector is resolved by Claude Code
+before requests are sent to the provider. The action's sanitized result output
+includes each model's resolved
+`contextWindow` and `maxOutputTokens` under `modelUsage`, so these limits are
+visible without enabling `show_full_output`.
+
+## 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@v1
+  with:
+    settings: "path/to/settings.json"
+    # ... other inputs
+```
+
+### Option 2: Inline Settings
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    settings: |
+      {
+        "model": "claude-opus-4-1-20250805",
+        "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.
+- The `claude_args` input provides direct access to Claude Code CLI arguments and takes precedence over settings.
+- We recommend using `claude_args` for simple configurations and `settings` for complex configurations with hooks and environment variables.
+
+## Migration from Deprecated Inputs
+
+Many individual input parameters have been consolidated into `claude_args` or `settings`. Here's how to migrate:
+
+| Old Input             | New Approach                                                    |
+| --------------------- | --------------------------------------------------------------- |
+| `allowed_tools`       | Use `claude_args: "--allowedTools Tool1,Tool2"`                 |
+| `disallowed_tools`    | Use `claude_args: "--disallowedTools Tool1,Tool2"`              |
+| `max_turns`           | Use `claude_args: "--max-turns 10"`                             |
+| `model`               | Use `claude_args: "--model claude-4-0-sonnet-20250805"`         |
+| `claude_env`          | Use `settings` with `"env"` object                              |
+| `custom_instructions` | Use `claude_args: "--append-system-prompt 'Your instructions'"` |
+| `mcp_config`          | Use `claude_args: "--mcp-config '{...}'"`                       |
+| `direct_prompt`       | Use `prompt` input instead                                      |
+| `override_prompt`     | Use `prompt` with GitHub context variables                      |
+
+## Custom Executables for Specialized Environments
+
+For specialized environments like Nix, custom container setups, or other package management systems where the default installation doesn't work, you can provide your own executables:
+
+### Custom Claude Code Executable
+
+Use `path_to_claude_code_executable` to provide your own Claude Code binary instead of using the automatically installed version:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    path_to_claude_code_executable: "/path/to/custom/claude"
+    # ... other inputs
+```
+
+### Custom Bun Executable
+
+Use `path_to_bun_executable` to provide your own Bun runtime instead of the default installation:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    path_to_bun_executable: "/path/to/custom/bun"
+    # ... other inputs
+```
+
+**Important**: Using incompatible versions may cause the action to fail. Ensure your custom executables are compatible with the action's requirements.

+# Custom Automations
+
+These examples show how to configure Claude to act automatically based on GitHub events. When you provide a `prompt` input, the action automatically runs in agent mode without requiring manual @mentions. Without a `prompt`, it runs in interactive mode, responding to @claude mentions.
+
+## Mode Detection & Tracking Comments
+
+The action automatically detects which mode to use based on your configuration:
+
+- **Interactive Mode** (no `prompt` input): Responds to @claude mentions, creates tracking comments with progress indicators
+- **Automation Mode** (with `prompt` input): Executes immediately, **does not create tracking comments**
+
+> **Note**: In v1, automation mode intentionally does not create tracking comments by default to reduce noise in automated workflows. If you need progress tracking, use the `track_progress: true` input parameter.
+
+## 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` or `pull_request_target` - 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
+- `workflow_dispatch` - Manual workflow triggers (coming soon)
+
+## Automated Documentation Updates
+
+Automatically update documentation when specific files change (see [`examples/pr-review-filtered-paths.yml`](../examples/pr-review-filtered-paths.yml)):
+
+```yaml
+on:
+  pull_request:
+    paths:
+      - "src/api/**/*.ts"
+
+steps:
+  - uses: anthropics/claude-code-action@v1
+    with:
+      prompt: |
+        Update the API documentation in README.md to reflect
+        the changes made to the API endpoints in this PR.
+      anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+When API files are modified, the action automatically detects that a `prompt` is provided and runs in agent mode. Claude 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/pr-review-filtered-authors.yml`](../examples/pr-review-filtered-authors.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@v1
+        with:
+          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.
+          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+Perfect for automatically reviewing PRs from new team members, external contributors, or specific developers who need extra guidance. The action automatically runs in agent mode when a `prompt` is provided.
+
+## Custom Prompt Templates
+
+Use the `prompt` input with GitHub context variables for dynamic automation:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: |
+      Analyze PR #${{ github.event.pull_request.number }} in ${{ github.repository }} for security vulnerabilities.
+
+      Focus on:
+      - SQL injection risks
+      - XSS vulnerabilities
+      - Authentication bypasses
+      - Exposed secrets or credentials
+
+      Provide severity ratings (Critical/High/Medium/Low) for any issues found.
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+You can access any GitHub context variable using the standard GitHub Actions syntax:
+
+- `${{ github.repository }}` - The repository name
+- `${{ github.event.pull_request.number }}` - PR number
+- `${{ github.event.issue.number }}` - Issue number
+- `${{ github.event.pull_request.title }}` - PR title
+- `${{ github.event.pull_request.body }}` - PR description
+- `${{ github.event.comment.body }}` - Comment text
+- `${{ github.actor }}` - User who triggered the workflow
+- `${{ github.base_ref }}` - Base branch for PRs
+- `${{ github.head_ref }}` - Head branch for PRs
+
+## Advanced Configuration with claude_args
+
+For more control over Claude's behavior, use the `claude_args` input to pass CLI arguments directly:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: "Review this PR for performance issues"
+    claude_args: |
+      --max-turns 15
+      --model claude-4-0-sonnet-20250805
+      --allowedTools Edit,Read,Write,Bash
+      --system-prompt "You are a performance optimization expert. Focus on identifying bottlenecks and suggesting improvements."
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+This provides full access to Claude Code CLI capabilities while maintaining the simplified action interface.

+# Experimental Features
+
+**Note:** Experimental features are considered unstable and not supported for production use. They may change or be removed at any time.
+
+## Automatic Mode Detection
+
+The action intelligently detects the appropriate execution mode based on your workflow context, eliminating the need for manual mode configuration.
+
+### Interactive Mode (Tag Mode)
+
+Activated when Claude detects @mentions, issue assignments, or labels—without an explicit `prompt`.
+
+- **Triggers**: `@claude` mentions in comments, issue assignment to claude user, label application
+- **Features**: Creates tracking comments with progress checkboxes, full implementation capabilities
+- **Use case**: Interactive code assistance, Q&A, and implementation requests
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    # No prompt needed - responds to @claude mentions
+```
+
+### Automation Mode (Agent Mode)
+
+Automatically activated when you provide a `prompt` input.
+
+- **Triggers**: Any GitHub event when `prompt` input is provided
+- **Features**: Direct execution without requiring @claude mentions, streamlined for automation
+- **Use case**: Automated PR reviews, scheduled tasks, workflow automation
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    prompt: |
+      Check for outdated dependencies and create an issue if any are found.
+    # Automatically runs in agent mode when prompt is provided
+```
+
+### How It Works
+
+The action uses this logic to determine the mode:
+
+1. **If `prompt` is provided** → Runs in **agent mode** for automation
+2. **If no `prompt` but @claude is mentioned** → Runs in **tag mode** for interaction
+3. **If neither** → No action is taken
+
+This automatic detection ensures your workflows are simpler and more intuitive, without needing to understand or configure different modes.
+
+### Advanced Mode Control
+
+For specialized use cases, you can fine-tune behavior using `claude_args`:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: "Review this PR"
+    claude_args: |
+      --max-turns 20
+      --system-prompt "You are a code review specialist"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```

+# Frequently Asked Questions (FAQ)
+
+This FAQ addresses common questions and gotchas when using the Claude Code GitHub Action.
+
+## Triggering and Authentication
+
+### Why doesn't tagging @claude from my automated workflow work?
+
+The `github-actions` user cannot trigger subsequent GitHub Actions workflows. This is a GitHub security feature to prevent infinite loops. To make this work, you need to use a Personal Access Token (PAT) instead, which will act as a regular user, or use a separate app token of your own. When posting a comment on an issue or PR from your workflow, use your PAT instead of the `GITHUB_TOKEN` generated in your workflow.
+
+### Why does Claude say I don't have permission to trigger it?
+
+Only users with **write permissions** to the repository can trigger Claude. This is a security feature to prevent unauthorized use. Make sure the user commenting has at least write access to the repository.
+
+### Why can't I assign @claude to an issue on my repository?
+
+If you're in a public repository, you should be able to assign to Claude without issue. If it's a private organization repository, you can only assign to users in your own organization, which Claude isn't. In this case, you'll need to make a custom user in that case.
+
+### Why am I getting OIDC authentication errors?
+
+If you're using the default GitHub App authentication, you must add the `id-token: write` permission to your workflow:
+
+```yaml
+permissions:
+  contents: read
+  id-token: write # Required for OIDC authentication
+```
+
+The OIDC token is required in order for the Claude GitHub app to function. If you wish to not use the GitHub app, you can instead provide a `github_token` input to the action for Claude to operate with. See the [Claude Code permissions documentation][perms] for more.
+
+### Why am I getting '403 Resource not accessible by integration' errors?
+
+This error occurs when the action tries to fetch the authenticated user information using a GitHub App installation token. GitHub App tokens have limited access and cannot access the `/user` endpoint, which causes this 403 error.
+
+**Solution**: The action now includes `bot_id` and `bot_name` inputs that default to Claude's bot credentials. This avoids the need to fetch user information from the API.
+
+For the default claude[bot]:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    # bot_id and bot_name have sensible defaults, no need to specify
+```
+
+For custom bots, specify both:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    bot_id: "12345678" # Your bot's GitHub user ID
+    bot_name: "my-bot" # Your bot's username
+```
+
+This issue typically only affects agent/automation mode workflows. Interactive workflows (with @claude mentions) don't encounter this issue as they use the comment author's information.
+
+## Claude's Capabilities and Limitations
+
+### Why won't Claude update workflow files when I ask it to?
+
+The GitHub App for Claude doesn't have workflow write access for security reasons. This prevents Claude from modifying CI/CD configurations that could potentially create unintended consequences. This is something we may reconsider in the future.
+
+### Why won't Claude rebase my branch?
+
+Claude only creates and pushes commits. It does not merge branches, rebase, force push, or perform other destructive git operations. Specifically, Claude is configured to:
+
+- Never push to branches other than where it was invoked (either its own branch or the PR branch)
+- Never force push or perform destructive operations
+
+This restriction is enforced in Claude's system prompt, so it applies even if you grant the underlying git tools (for example `--allowedTools "Bash(git rebase:*)"`). In that case Claude will still decline rebase requests and explain the limitation rather than running the command.
+
+If you need to rebase, do it yourself locally — or with the Claude Code CLI outside of this action — and push the result.
+
+### Why won't Claude create a pull request?
+
+Claude doesn't create PRs by default. Instead, it pushes commits to a branch and provides a link to a pre-filled PR submission page. This approach ensures your repository's branch protection rules are still adhered to and gives you final control over PR creation.
+
+### Can Claude see my GitHub Actions CI results?
+
+Yes! Claude can access GitHub Actions workflow runs, job logs, and test results on the PR where it's tagged. To enable this:
+
+1. Add `actions: read` permission to your workflow:
+
+   ```yaml
+   permissions:
+     contents: write
+     pull-requests: write
+     issues: write
+     actions: read
+   ```
+
+2. Configure the action with additional permissions:
+   ```yaml
+   - uses: anthropics/claude-code-action@v1
+     with:
+       additional_permissions: |
+         actions: read
+   ```
+
+Claude will then be able to analyze CI failures and help debug workflow issues. For running tests locally before commits, you can still instruct Claude to do so in your request.
+
+### Why does Claude only update one comment instead of creating new ones?
+
+Claude is configured to update a single comment to avoid cluttering PR/issue discussions. All of Claude's responses, including progress updates and final results, will appear in the same comment with checkboxes showing task progress.
+
+## Branch and Commit Behavior
+
+### Why did Claude create a new branch when commenting on a closed PR?
+
+Claude's branch behavior depends on the context:
+
+- **Open PRs**: Pushes directly to the existing PR branch
+- **Closed/Merged PRs**: Creates a new branch (cannot push to closed PR branches)
+- **Issues**: Always creates a new branch with a timestamp
+
+### Why are my commits shallow/missing history?
+
+For performance, Claude uses shallow clones:
+
+- PRs: `--depth=20` (last 20 commits)
+- New branches: `--depth=1` (single commit)
+
+If you need full history, you can configure this in your workflow before calling Claude in the `actions/checkout` step.
+
+```
+- uses: actions/checkout@v6
+  depth: 0 # will fetch full repo history
+```
+
+## Configuration and Tools
+
+### How does automatic mode detection work?
+
+The action intelligently detects whether to run in interactive mode or automation mode:
+
+- **With `prompt` input**: Runs in automation mode - executes immediately without waiting for @claude mentions
+- **Without `prompt` input**: Runs in interactive mode - waits for @claude mentions in comments
+
+This automatic detection eliminates the need to manually configure modes.
+
+Example:
+
+```yaml
+# Automation mode - runs automatically
+prompt: "Review this PR for security vulnerabilities"
+# Interactive mode - waits for @claude mention
+# (no prompt provided)
+```
+
+### What happened to `direct_prompt` and `custom_instructions`?
+
+**These inputs are deprecated in v1.0:**
+
+- **`direct_prompt`** → Use `prompt` instead
+- **`custom_instructions`** → Use `claude_args` with `--append-system-prompt` (appends to the default system prompt, matching v0 behavior; `--system-prompt` replaces it entirely)
+
+Migration examples:
+
+```yaml
+# Old (v0.x)
+direct_prompt: "Review this PR"
+custom_instructions: "Focus on security"
+
+# New (v1.0)
+prompt: "Review this PR"
+claude_args: |
+  --append-system-prompt "Focus on security"
+```
+
+### Why doesn't Claude execute my bash commands?
+
+The Bash tool is **disabled by default** for security. To enable individual bash commands using `claude_args`:
+
+```yaml
+claude_args: |
+  --allowedTools "Bash(npm:*),Bash(git:*)"  # Allows only npm and git commands
+```
+
+### Can Claude work across multiple repositories?
+
+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.
+
+## MCP Servers and Extended Functionality
+
+### What MCP servers are available by default?
+
+Claude Code Action automatically configures two MCP servers:
+
+1. **GitHub MCP server**: For GitHub API operations
+2. **File operations server**: For advanced file manipulation
+
+However, tools from these servers still need to be explicitly allowed via `claude_args` with `--allowedTools`.
+
+## Troubleshooting
+
+### How can I debug what Claude is doing?
+
+Check the GitHub Action log for Claude's run for the full execution trace.
+
+### Why can't I trigger Claude with `@claude-mention` or `claude!`?
+
+The trigger uses word boundaries, so `@claude` must be a complete word. Variations like `@claude-bot`, `@claude!`, or `claude@mention` won't work unless you customize the `trigger_phrase`.
+
+### How can I use custom executables in specialized environments?
+
+For specialized environments like Nix, NixOS, or custom container setups where you need to provide your own executables:
+
+**Using a custom Claude Code executable:**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    path_to_claude_code_executable: "/path/to/custom/claude"
+    # ... other inputs
+```
+
+**Using a custom Bun executable:**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    path_to_bun_executable: "/path/to/custom/bun"
+    # ... other inputs
+```
+
+**Common use cases:**
+
+- Nix/NixOS environments where packages are managed differently
+- Docker containers with pre-installed executables
+- Custom build environments with specific version requirements
+- Debugging specific issues with particular versions
+
+**Important notes:**
+
+- Using an older Claude Code version may cause problems if the action uses newer features
+- Using an incompatible Bun version may cause runtime errors
+- The action will skip automatic installation when custom paths are provided
+- Ensure the custom executables are available in your GitHub Actions environment
+
+## Best Practices
+
+1. **Always specify permissions explicitly** in your workflow file
+2. **Use GitHub Secrets** for API keys - never hardcode them
+3. **Be specific with tool permissions** - only enable what's necessary via `claude_args`
+4. **Test in a separate branch** before using on important PRs
+5. **Monitor Claude's token usage** to avoid hitting API limits
+6. **Review Claude's changes** carefully before merging

+
+## Migration Examples
+
+### Basic Interactive Workflow (@claude mentions)
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: "tag"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    custom_instructions: "Follow our coding standards"
+    max_turns: "10"
+    allowed_tools: "Edit,Read,Write"
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --max-turns 10
+      --append-system-prompt "Follow our coding standards"
+      --allowedTools Edit,Read,Write
+```
+
+### Automation Workflow
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: "agent"
+    direct_prompt: "Review this PR for security issues"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    model: "claude-3-5-sonnet-20241022"
+    allowed_tools: "Edit,Read,Write"
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: |
+      REPO: ${{ github.repository }}
+      PR NUMBER: ${{ github.event.pull_request.number }}
+
+      Review this PR for security issues
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --model claude-4-0-sonnet-20250805
+      --allowedTools Edit,Read,Write
+```
+
+> **⚠️ Important**: For PR reviews, always include the repository and PR context in your prompt. This ensures Claude knows which PR to review.
+
+### Automation with Progress Tracking (New in v1.0)
+
+**Missing the tracking comments from v0.x agent mode?** The new `track_progress` input brings them back!
+
+In v1.0, automation mode (with `prompt` input) doesn't create tracking comments by default to reduce noise. However, if you need progress visibility, you can use the `track_progress` feature:
+
+**Before (v0.x with tracking):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: "agent"
+    direct_prompt: "Review this PR for security issues"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+**After (v1.0 with tracking):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    track_progress: true # Forces tag mode with tracking comments
+    prompt: |
+      REPO: ${{ github.repository }}
+      PR NUMBER: ${{ github.event.pull_request.number }}
+
+      Review this PR for security issues
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+#### Benefits of `track_progress`
+
+1. **Preserves GitHub Context**: Automatically includes all PR/issue details, comments, and attachments
+2. **Brings Back Tracking Comments**: Creates progress indicators just like v0.x agent mode
+3. **Works with Custom Prompts**: Your `prompt` is injected as custom instructions while maintaining context
+
+#### Supported Events for `track_progress`
+
+The `track_progress` input only works with these GitHub events:
+
+**Pull Request Events:**
+
+- `opened` - New PR created
+- `synchronize` - PR updated with new commits
+- `ready_for_review` - Draft PR marked as ready
+- `reopened` - Previously closed PR reopened
+
+**Issue Events:**
+
+- `opened` - New issue created
+- `edited` - Issue title or body modified
+- `labeled` - Label added to issue
+- `assigned` - Issue assigned to user
+
+> **Note**: Using `track_progress: true` with unsupported events will cause an error.
+
+### Custom Template with Variables
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    override_prompt: |
+      Analyze PR #$PR_NUMBER in $REPOSITORY
+      Changed files: $CHANGED_FILES
+      Focus on security vulnerabilities
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: |
+      REPO: ${{ github.repository }}
+      PR NUMBER: ${{ github.event.pull_request.number }}
+
+      Analyze this pull request focusing on security vulnerabilities in the changed files.
+
+      Note: The PR branch is already checked out in the current working directory.
+```
+
+> **💡 Tip**: While you can access GitHub context variables in your prompt, it's recommended to use the standard `REPO:` and `PR NUMBER:` format for consistency.
+
+### Environment Variables
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    claude_env: |
+      NODE_ENV: test
+      CI: true
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    settings: |
+      {
+        "env": {
+          "NODE_ENV": "test",
+          "CI": "true"
+        }
+      }
+```
+
+### Timeout Configuration
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    timeout_minutes: 30
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+**After (v1.0):**
+
+```yaml
+jobs:
+  claude-task:
+    runs-on: ubuntu-latest
+    timeout-minutes: 30 # Moved to job level
+    steps:
+      - uses: anthropics/claude-code-action@v1
+        with:
+          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+## How Mode Detection Works
+
+The action now automatically detects the appropriate mode:
+
+1. **If `prompt` is provided** → Runs in **automation mode**
+
+   - Executes immediately without waiting for @claude mentions
+   - Perfect for scheduled tasks, PR automation, etc.
+
+2. **If no `prompt` but @claude is mentioned** → Runs in **interactive mode**
+
+   - Waits for and responds to @claude mentions
+   - Creates tracking comments with progress
+
+3. **If neither** → No action is taken
+
+## Advanced Configuration with claude_args
+
+The `claude_args` input provides direct access to Claude Code CLI arguments:
+
+```yaml
+claude_args: |
+  --max-turns 15
+  --model claude-4-0-sonnet-20250805
+  --allowedTools Edit,Read,Write,Bash
+  --disallowedTools WebSearch
+  --system-prompt "You are a senior engineer focused on code quality"
+  --mcp-config '{"mcpServers": {"custom": {"command": "npx", "args": ["-y", "@example/server"]}}}'
+```
+
+### Common claude_args Options
+
+| Option                   | Description                                                               | Example                                                |
+| ------------------------ | ------------------------------------------------------------------------- | ------------------------------------------------------ |
+| `--max-turns`            | Limit conversation turns                                                  | `--max-turns 10`                                       |
+| `--model`                | Specify Claude model                                                      | `--model claude-4-0-sonnet-20250805`                   |
+| `--allowedTools`         | Enable specific tools                                                     | `--allowedTools Edit,Read,Write`                       |
+| `--disallowedTools`      | Disable specific tools                                                    | `--disallowedTools WebSearch`                          |
+| `--system-prompt`        | Replace the entire default system prompt                                  | `--system-prompt "Focus on security"`                  |
+| `--append-system-prompt` | Append to the default system prompt (keeps Claude Code's built-in prompt) | `--append-system-prompt "Follow our coding standards"` |
+| `--mcp-config`           | Add MCP server config                                                     | `--mcp-config '{"mcpServers": {...}}'`                 |

+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    claude_args: |
+      --mcp-config '{"mcpServers": {"custom-server": {"command": "npx", "args": ["-y", "@example/server"]}}}'
+```
+
+You can also pass MCP configuration from a file:

+# Security
+
+## Access Control
+
+- **Repository Access**: The action can only be triggered by users with write access to the repository. This is checked for issue, pull request, comment, and review events, and for `workflow_run` events, where both the workflow actor and the actor that started the upstream run are checked. `workflow_dispatch`, `repository_dispatch`, and `schedule` events are not checked separately — GitHub itself requires write access to dispatch a workflow, and scheduled runs have no external actor.
+- **Bot User Control**: By default, GitHub Apps and bots cannot trigger this action for security reasons. Use the `allowed_bots` parameter to enable specific bots or all bots
+  - **⚠️ Allowed bots are not checked for repository permissions.** A bot that matches an entry does **not** need to be installed on your repository or have write access. On a **public repository**, external parties — including GitHub Apps created by anyone — may be able to trigger workflow events such as opening issues, commenting, or reviewing pull requests. If your workflow listens on those events and `allowed_bots` is set to `'*'`, any such App can invoke this action with a prompt it controls.
+  - Prefer an explicit list over `'*'`
+  - Only list App names you trust
+  - If you need `'*'`, scope workflow `permissions:` to the minimum required
+- **⚠️ Non-Write User Access (RISKY)**: The `allowed_non_write_users` parameter allows bypassing the write permission requirement. **This is a significant security risk and should only be used for workflows with extremely limited permissions** (e.g., issue labeling workflows that only have `issues: write` permission). This feature:
+  - Only works when `github_token` is provided as input (not with GitHub App authentication)
+  - Accepts either a comma-separated list of specific usernames or `*` to allow all users
+  - **Should be used with extreme caution** as it bypasses the primary security mechanism of this action
+  - Is designed for automation workflows where user permissions are already restricted by the workflow's permission scope
+  - When set, Claude does a best-effort scrub of Anthropic, cloud, and GitHub Actions secrets from subprocess environments. On Linux runners with bubblewrap available, subprocesses additionally run with PID-namespace isolation. This reduces but does not eliminate prompt injection risk — keep workflow permissions minimal and validate all outputs. Set `CLAUDE_CODE_SUBPROCESS_ENV_SCRUB: 0` in your workflow or job `env:` block to opt out.
+  - Optionally set `CLAUDE_CODE_SCRIPT_CAPS` in your workflow `env:` block to limit how many times Claude can call specific scripts per run. Value is JSON: `{"script-name.sh": maxCalls}`. Example: `CLAUDE_CODE_SCRIPT_CAPS: '{"edit-issue-labels.sh":2}'` allows at most 2 calls to `edit-issue-labels.sh`. Useful for write-capable helper scripts.
+  - When using `allowed_non_write_users`, always pass `github_token: ${{ secrets.GITHUB_TOKEN }}`. The auto-generated workflow token is scoped to the job's declared permissions and expires when the job completes. **Do not use a personal access token** — a static token does not rotate between runs and could be partially or fully recovered over time via prompt injection. Restricting allowed tools via `claude_args` reduces the rate of recovery but may not eliminate the risk. We recommend restricting allowed tools (e.g. `claude_args: '--allowedTools "Bash(gh issue view:*)"'`) to the minimum required when using `allowed_non_write_users`.
+- **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
+
+## Using this action with `pull_request_target` or `workflow_run`
+
+For `workflow_run` events, the action checks the repository access of the actor that started the upstream run (for example, the author of the fork pull request that triggered your CI workflow) in addition to the workflow actor. If that actor does not have write access, the action stops before running Claude. To run on `workflow_run` events downstream of pull requests from contributors without write access, add those users to `allowed_non_write_users` and pass `github_token: ${{ secrets.GITHUB_TOKEN }}` — see the notes on that input above and keep the workflow's permissions minimal.
+
+`pull_request_target` and `workflow_run` execute with the **base repository's secrets**. If your workflow checks out the PR head (`ref: ${{ github.event.pull_request.head.sha }}` for `pull_request_target`, `ref: ${{ github.event.workflow_run.head_sha }}` for `workflow_run`) into `$GITHUB_WORKSPACE` before this action, the action and Claude run with that checkout as the working directory.
+
+**Do not check out an untrusted ref into the workspace root before this action.** Use one of these patterns instead:
+
+```yaml
+# Preferred — check out the base ref (default).
+- uses: actions/checkout@v6 # no `ref:` → base branch
+- uses: anthropics/claude-code-action@v1
+```
+
+```yaml
+# If you need the PR's files locally — check out the base ref at the workspace
+# root (this action expects a git repo there), then check out the head ref into
+# a subdirectory and pass it via --add-dir.
+- uses: actions/checkout@v6 # no `ref:` → base branch at workspace root
+- uses: actions/checkout@v6
+  with:
+    # For workflow_run use: ${{ github.event.workflow_run.head_sha }}
+    ref: ${{ github.event.pull_request.head.sha }}
+    path: pr-head
+- uses: anthropics/claude-code-action@v1
+  with:
+    claude_args: "--add-dir pr-head"
+```
+
+This is general guidance for these event types — see [GitHub's documentation](https://securitylab.github.com/research/github-actions-preventing-pwn-requests/).
+
+### Which files come from the base branch on pull requests
+
+When the action runs against a pull request, it restores a fixed list of Claude configuration paths from the PR base branch before starting Claude: `.claude/`, `.mcp.json`, `.claude.json`, `.gitmodules`, `.ripgreprc`, `CLAUDE.md`, `CLAUDE.local.md`, and `.husky/`. Paths in that list that do not exist on the base branch are removed, and the PR-authored versions are kept under `.claude-pr/` for reference only.
+
+Everything else in the working tree — including `package.json`, lockfiles, `Makefile`, `node_modules/`, and formatter/linter config files — stays at the PR head. If a hook, `apiKeyHelper`, or `statusLine` command in your base-branch `.claude/settings.json` runs a package-manager script (`bun run …`, `npm run …`, `yarn …`, `pnpm run …`), a `make` target, a repo-relative script, or a tool that loads executable project config, that command resolves through files the pull request supplies. Keep such commands self-contained: invoke the tool directly with a pinned version and pass its configuration on the command line (for example `bunx prettier@3.5.3 --no-config --write .` rather than `bun run format`).
+
+Note that the runtime executing the tool also reads project config. `bunx <tool>` runs the tool's script under `node` when `node` is on `PATH` (as it is on GitHub-hosted runners); when only Bun is available, Bun executes the script itself and reads `bunfig.toml` from the checkout — including `preload` entries — which comes from the PR head. On such runners, make sure `node` is on `PATH` for the hook, and treat `bunfig.toml` and `.npmrc` in the checkout as PR-controlled runtime config.
+
+### `claude-code-action` vs `claude-code-base-action`
+
+`claude-code-base-action` is a lower-level building block that installs and runs Claude Code with the inputs you provide. It does not perform actor permission checks or restore project configuration from the base ref. If you need those behaviors, use this action (`claude-code-action`). See the [base-action README](../base-action/README.md#trust-model) for details.
+
+## Pull Request Creation
+
+In its default configuration, **Claude does not create pull requests automatically** when responding to `@claude` mentions. Instead:
+
+- Claude commits code changes to a new branch
+- Claude provides a **link to the GitHub PR creation page** in its response
+- **The user must click the link and create the PR themselves**, ensuring human oversight before any code is proposed for merging
+
+This design ensures that users retain full control over what pull requests are created and can review the changes before initiating the PR workflow.
+
+## ⚠️ Prompt Injection Risks
+
+**Beware of potential hidden markdown when tagging Claude on untrusted content.** External contributors may include hidden instructions through HTML comments, invisible characters, hidden attributes, or other techniques. The action sanitizes content by stripping HTML comments, invisible characters, markdown image alt text, hidden HTML attributes, and HTML entities, but new bypass techniques may emerge. We recommend reviewing the raw content of all input coming from external contributors before allowing Claude to process it.
+
+On public repos, you can also use `include_comments_by_actor` to allowlist which users' comments are passed to Claude, reducing exposure to untrusted input. Use `exclude_comments_by_actor` to filter out noisy bot comments (e.g., `dependabot[bot]`, `renovate[bot]`). If an actor matches both lists, exclusion takes priority. See [Usage](./usage.md) for details.
+
+## GitHub App Permissions
+
+The [Claude Code GitHub app](https://github.com/apps/claude) requests the following permissions:
+
+### Currently Used Permissions
+
+- **Contents** (Read & Write): For reading repository files and creating branches
+- **Pull Requests** (Read & Write): For reading PR data and creating/updating pull requests
+- **Issues** (Read & Write): For reading issue data and updating issue comments
+
+### Permissions for Future Features
+
+The following permissions are requested but not yet actively used. These will enable planned features in future releases:
+
+- **Discussions** (Read & Write): For interaction with GitHub Discussions
+- **Actions** (Read): For accessing workflow run data and logs
+- **Checks** (Read): For reading check run results
+- **Workflows** (Read & Write): For triggering and managing GitHub Actions workflows
+
+## Commit Signing
+
+By default, commits made by Claude are unsigned. You can enable commit signing using one of two methods:
+
+### Option 1: GitHub API Commit Signing (use_commit_signing)
+
+This uses GitHub's API to create commits, which automatically signs them as verified from the GitHub App:
+
+```yaml
+- uses: anthropics/claude-code-action@main
+  with:
+    use_commit_signing: true
+```
+
+This is the simplest option and requires no additional setup. However, because it uses the GitHub API instead of git CLI, it cannot perform complex git operations like rebasing, cherry-picking, or interactive history manipulation.
+
+### Option 2: SSH Signing Key (ssh_signing_key)
+
+This uses an SSH key to sign commits via git CLI. Use this option when you need both signed commits AND standard git operations (rebasing, cherry-picking, etc.):
+
+```yaml
+- uses: anthropics/claude-code-action@main
+  with:
+    ssh_signing_key: ${{ secrets.SSH_SIGNING_KEY }}
+    bot_id: "YOUR_GITHUB_USER_ID"
+    bot_name: "YOUR_GITHUB_USERNAME"
+```
+
+Commits will show as verified and attributed to the GitHub account that owns the signing key.
+
+**Setup steps:**
+
+1. Generate an SSH key pair for signing:
+
+   ```bash
+   ssh-keygen -t ed25519 -f ~/.ssh/signing_key -N "" -C "commit signing key"
+   ```
+
+2. Add the **public key** to your GitHub account:
+
+   - Go to GitHub → Settings → SSH and GPG keys
+   - Click "New SSH key"
+   - Select **Key type: Signing Key** (important)
+   - Paste the contents of `~/.ssh/signing_key.pub`
+
+3. Add the **private key** to your repository secrets:
+
+   - Go to your repo → Settings → Secrets and variables → Actions
+   - Create a new secret named `SSH_SIGNING_KEY`
+   - Paste the contents of `~/.ssh/signing_key`
+
+4. Get your GitHub user ID:
+
+   ```bash
+   gh api users/YOUR_USERNAME --jq '.id'
+   ```
+
+5. Update your workflow with `bot_id` and `bot_name` matching the account where you added the signing key.
+
+**Note:** If both `ssh_signing_key` and `use_commit_signing` are provided, `ssh_signing_key` takes precedence.
+
+## ⚠️ 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!
+```
+
+## ⚠️ Full Output Security Warning
+
+The `show_full_output` option is **disabled by default** for security reasons. When enabled, it outputs ALL Claude Code messages including:
+
+- Full outputs from tool executions (e.g., `ps`, `env`, file reads)
+- API responses that may contain tokens or credentials
+- File contents that may include secrets
+- Command outputs that may expose sensitive system information
+
+**These logs are publicly visible in GitHub Actions for public repositories!**
+
+### Automatic Enabling in Debug Mode
+
+Full output is **automatically enabled** when GitHub Actions debug mode is active (when `ACTIONS_STEP_DEBUG` secret is set to `true`). This helps with debugging but carries the same security risks.
+
+### When to Enable Full Output
+
+Only enable `show_full_output: true` or GitHub Actions debug mode when:
+
+- Working in a private repository with controlled access
+- Debugging issues in a non-production environment
+- You have verified no secrets will be exposed in the output
+- You understand the security implications
+
+### Recommended Practice
+
+For debugging, prefer using `show_full_output: false` (the default) and rely on Claude Code's sanitized output, which shows only essential information like errors and completion status without exposing sensitive data.

+# 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/`
+
+> Don't want to store a static API key at all? See [Workload Identity Federation](#workload-identity-federation) below.
+
+## Workload Identity Federation
+
+Workload Identity Federation (WIF) lets the action authenticate to the Claude API by exchanging the workflow's GitHub Actions OIDC token for a short-lived Anthropic access token — no `ANTHROPIC_API_KEY` secret to create, store, or rotate.
+
+### One-time setup in the Claude Console
+
+You need admin access to your Anthropic organization (Console → **Settings → Workload identity**):
+
+1. **Register an issuer** for GitHub Actions with issuer URL `https://token.actions.githubusercontent.com` (JWKS source: `discovery`).
+2. **Create a service account** (Settings → Service accounts) and add it to the workspace it should act in. Note the `svac_...` ID.
+3. **Create a federation rule** targeting that service account, matched to your repository's OIDC claims (for example a subject prefix of `repo:your-org/your-repo:`). Note the `fdrl_...` rule ID.
+
+See the [Workload Identity Federation documentation](https://platform.claude.com/docs/en/manage-claude/workload-identity-federation) for full details.
+
+### Workflow configuration
+
+```yaml
+jobs:
+  claude-response:
+    runs-on: ubuntu-latest
+    permissions:
+      contents: write
+      pull-requests: write
+      issues: write
+      id-token: write # required: used to fetch the GitHub OIDC token
+    steps:
+      - uses: anthropics/claude-code-action@v1
+        with:
+          anthropic_federation_rule_id: fdrl_xxxxxxxxxxxx
+          anthropic_organization_id: 00000000-0000-0000-0000-000000000000
+          anthropic_service_account_id: svac_xxxxxxxxxxxx
+          # Optional when the federation rule targets a single workspace:
+          anthropic_workspace_id: wrkspc_xxxxxxxxxxxx
+```
+
+These values are identifiers, not credentials, so they can live directly in the workflow file (or in repository variables).
+
+Notes:
+
+- The workflow must grant `id-token: write` permission so the action can fetch a GitHub OIDC token. The default GitHub App authentication path already requires this permission.
+- Do not set `anthropic_api_key` or `claude_code_oauth_token` alongside the federation inputs — a static credential takes precedence and federation will not be used.
+- The GitHub OIDC token is requested with audience `https://api.anthropic.com` by default, so set the federation rule's expected audience to that value (or leave the rule's audience unmatched). Use `anthropic_oidc_audience` only if your rule expects a different audience.
+- Inline comment classification (`classify_inline_comments`) currently requires `anthropic_api_key`; with federation it is skipped and unconfirmed inline comments are posted directly.
+
+## 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
+
+### Option 1: Quick Setup with App Manifest (Recommended)
+
+The fastest way to create a custom GitHub App is using our pre-configured manifest. This ensures all permissions are correctly set up with a single click.
+
+**Steps:**
+
+1. **Create the app:**
+
+   **🚀 [Download the Quick Setup Tool](./create-app.html)** (Right-click → "Save Link As" or "Download Linked File")
+
+   After downloading, open `create-app.html` in your web browser:
+
+   - **For Personal Accounts:** Click the "Create App for Personal Account" button
+   - **For Organizations:** Enter your organization name and click "Create App for Organization"
+
+   The tool will automatically configure all required permissions and submit the manifest.
+
+   Alternatively, you can use the manifest file directly:
+
+   - Use the [`github-app-manifest.json`](../github-app-manifest.json) file from this repository
+   - Visit https://github.com/settings/apps/new (for personal) or your organization's app settings
+   - Look for the "Create from manifest" option and paste the JSON content
+
+2. **Complete the creation flow:**
+
+   - GitHub will show you a preview of the app configuration
+   - Confirm the app name (you can customize it)
+   - Click "Create GitHub App"
+   - The app will be created with all required permissions automatically configured
+
+3. **Generate and download a private key:**
+
+   - After creating the app, you'll be redirected to the app settings
+   - Scroll down to "Private keys"
+   - Click "Generate a private key"
+   - Download the `.pem` file (keep this secure!)
+
+4. **Continue with installation** - Skip to step 3 in the manual setup below to install the app and configure your workflow.
+
+### Option 2: Manual Setup
+
+If you prefer to configure the app manually or need custom permissions:
+
+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@v1
+           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
+
+For more information on creating GitHub Apps, see the [GitHub documentation](https://docs.github.com/en/apps/creating-github-apps).
+
+## 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

+            --allowedTools "mcp__github_inline_comment__create_inline_comment,Bash(gh pr comment:*),Bash(gh pr diff:*),Bash(gh pr view:*)"
+```
+
+**Key Configuration:**
+
+- Triggers on `opened` and `synchronize` (new commits)
+- Always include `REPO` and `PR NUMBER` for context
+- Specify tools for commenting and reviewing
+- PR branch is pre-checked out
+
+**Expected Output:** Claude posts review comments directly to the PR with inline annotations where appropriate.
+
+### Enhanced Example (With Progress Tracking)
+
+Want visual progress tracking for PR reviews? Use `track_progress: true` to get tracking comments like in v0.x:
+
+```yaml
+name: Claude Auto Review with Tracking
+on:
+  pull_request:
+    types: [opened, synchronize, ready_for_review, reopened]
+
+jobs:
+  review:
+    runs-on: ubuntu-latest
+    permissions:
+      contents: read
+      pull-requests: write
+      id-token: write
+    steps:
+      - uses: actions/checkout@v6
+        with:
+          fetch-depth: 1
+
+      - uses: anthropics/claude-code-action@v1
+        with:
+          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+          track_progress: true # ✨ Enables tracking comments
+          prompt: |
+            REPO: ${{ github.repository }}
+            PR NUMBER: ${{ github.event.pull_request.number }}
+
+            Please review this pull request with a focus on:

+            --allowedTools "mcp__github_inline_comment__create_inline_comment,Bash(gh pr comment:*),Bash(gh pr diff:*),Bash(gh pr view:*)"
+```
+
+**Benefits of Progress Tracking:**
+
+- **Visual Progress Indicators**: Shows "In progress" status with checkboxes
+- **Preserves Full Context**: Automatically includes all PR details, comments, and attachments
+- **Migration-Friendly**: Perfect for teams moving from v0.x who miss tracking comments
+- **Works with Custom Prompts**: Your prompt becomes custom instructions while maintaining GitHub context
+
+**Expected Output:**
+
+1. Claude creates a tracking comment: "Claude Code is reviewing this pull request..."
+2. Updates the comment with progress checkboxes as it works
+3. Posts detailed review feedback with inline annotations
+4. Updates tracking comment to "Completed" when done

+## Tips for All Solutions
+
+### Always Include GitHub Context
+
+```yaml
+prompt: |
+  REPO: ${{ github.repository }}
+  PR NUMBER: ${{ github.event.pull_request.number }}
+  [Your specific instructions]
+```
+
+### Common Tool Permissions
+
+- **PR Comments**: `Bash(gh pr comment:*)`
+- **Inline Comments**: `mcp__github_inline_comment__create_inline_comment` — pass `confirmed: true` to post immediately. When omitted, the comment is buffered and classified after the session ends (real review comments post, test/probe comments are filtered). This prevents subagent test comments from reaching PRs. To disable classification entirely, set `classify_inline_comments: 'false'` on the action.
+- **File Operations**: `Read,Write,Edit`
+- **Git Operations**: `Bash(git:*)`
+
+### Best Practices
+
+- Be specific in your prompts
+- Include expected output format
+- Set clear success criteria
+- Provide context about the repository
+- Use inline comments for code-specific feedback

+
+## Upgrading from v0.x?
+
+For a comprehensive guide on migrating from v0.x to v1.0, including step-by-step instructions and examples, see our **[Migration Guide](./migration-guide.md)**.
+
+### Quick Migration Examples
+
+#### Interactive Workflows (with @claude mentions)
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: "tag"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    custom_instructions: "Focus on security"
+    max_turns: "10"
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --max-turns 10
+      --append-system-prompt "Focus on security"
+```
+
+#### Automation Workflows
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: "agent"
+    direct_prompt: "Update the API documentation"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    model: "claude-4-0-sonnet-20250805"
+    allowed_tools: "Edit,Read,Write"
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: |
+      REPO: ${{ github.repository }}
+      PR NUMBER: ${{ github.event.pull_request.number }}
+
+      Update the API documentation to reflect changes in this PR
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --model claude-4-0-sonnet-20250805
+      --allowedTools Edit,Read,Write
+```
+
+#### Custom Templates
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    override_prompt: |
+      Analyze PR #$PR_NUMBER for security issues.
+      Focus on: $CHANGED_FILES
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: |
+      Analyze PR #${{ github.event.pull_request.number }} for security issues.
+      Focus on the changed files in this PR.
+```
+
+## Structured Outputs
+
+Get validated JSON results from Claude that automatically become GitHub Action outputs. This enables building complex automation workflows where Claude analyzes data and subsequent steps use the results.
+
+### Basic Example
+
+```yaml
+- name: Detect flaky tests
+  id: analyze
+  uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    prompt: |
+      Check the CI logs and determine if this is a flaky test.
+      Return: is_flaky (boolean), confidence (0-1), summary (string)
+    claude_args: |
+      --json-schema '{"type":"object","properties":{"is_flaky":{"type":"boolean"},"confidence":{"type":"number"},"summary":{"type":"string"}},"required":["is_flaky"]}'
+
+- name: Retry if flaky
+  if: fromJSON(steps.analyze.outputs.structured_output).is_flaky == true
+  run: gh workflow run CI
+```
+
+### How It Works
+
+1. **Define Schema**: Provide a JSON schema via `--json-schema` flag in `claude_args`
+2. **Claude Executes**: Claude uses tools to complete your task
+3. **Validated Output**: Result is validated against your schema
+4. **JSON Output**: All fields are returned in a single `structured_output` JSON string
+
+### Accessing Structured Outputs
+
+All structured output fields are available in the `structured_output` output as a JSON string:
+
+**In GitHub Actions expressions:**
+
+```yaml
+if: fromJSON(steps.analyze.outputs.structured_output).is_flaky == true
+run: |
+  CONFIDENCE=${{ fromJSON(steps.analyze.outputs.structured_output).confidence }}
+```
+
+**In bash with jq:**
+
+```yaml
+- name: Process results
+  run: |
+    OUTPUT='${{ steps.analyze.outputs.structured_output }}'
+    IS_FLAKY=$(echo "$OUTPUT" | jq -r '.is_flaky')
+    SUMMARY=$(echo "$OUTPUT" | jq -r '.summary')
+```
+
+**Note**: Due to GitHub Actions limitations, composite actions cannot expose dynamic outputs. All fields are bundled in the single `structured_output` JSON string.
+
+### Complete Example
+
+See `examples/test-failure-analysis.yml` for a working example that:
+
+- Detects flaky test failures
+- Uses confidence thresholds in conditionals
+- Auto-retries workflows
+- Comments on PRs

+
+## 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.
