## Key Components
### 1. Token Exchange Process
The action uses a secure OIDC token exchange system:
1. **OIDC Token Generation**: `core.getIDToken("claude-code-github-action")`
2. **Token Exchange**: POST to `https://api.anthropic.com/api/github/github-app-token-exchange`
3. **Authentication**: Creates authenticated Octokit clients for GitHub API access
**Security Benefits:**
- Repository-scoped access
- Time-limited tokens
- Permission-limited (only configured GitHub App permissions)
- Automatic token masking in logs
### 2. Mode Detection
The action automatically detects the appropriate execution mode:
#### **Agent Mode**
- **Trigger**: Explicit `prompt` input provided
- **Use Case**: Direct automation, custom workflows
- **Behavior**: Minimal context, direct execution
- **Tracking**: No tracking comments
#### **Tag Mode**
- **Trigger**: @claude mentions, issue assignments, or labels
- **Use Case**: Interactive GitHub responses
- **Behavior**: Rich context, comprehensive GitHub data
- **Tracking**: Creates and updates tracking comments
### 3. Data Fetching (Tag Mode)
When in Tag Mode, the action fetches comprehensive GitHub context:
#### **Pull Request Data:**
- Comments and reviews (including inline comments)
- Changed files with SHAs
- Commit history and metadata
- Author information
- File diff data
#### **Issue Data:**
- Issue details and metadata
- All comments
- Author information
- Labels and assignments
#### **Image Processing:**
- Downloads images from GitHub
- Converts to base64 for Claude
- Maps original URLs to processed content
### 4. MCP Server Integration
The action sets up multiple MCP (Model Context Protocol) servers to provide Claude with GitHub capabilities:
#### **GitHub Actions Server**
- Access to workflow runs and CI data
- Build status and test results
- Artifact information
#### **GitHub Comment Server**
- Comment creation and updates
- Issue and PR comment management
#### **GitHub File Operations Server**
- File reading and writing
- Branch creation and management
- Commit operations
#### **GitHub Inline Comment Server**
- PR review comment operations
- Line-specific feedback
### 5. Prompt Generation
The action generates context-rich prompts based on the detected mode:
#### **Agent Mode Prompts:**
- Direct user prompt
- Minimal GitHub context
- Focused on specific task
#### **Tag Mode Prompts:**
- Comprehensive GitHub context
- PR/Issue details and history
- Changed files and diffs
- Comment threads and reviews
- Commit instructions and guidelines
### 6. Claude Execution
The action runs Claude Code through multiple provider options:
#### **Provider Support:**
- **Anthropic API** (default): Direct API access with API key
- **AWS Bedrock**: OIDC authentication with AWS credentials
- **GCP Vertex AI**: OIDC authentication with GCP credentials
#### **Execution Process:**
1. **Named Pipe Setup**: Creates pipe for prompt input
2. **Process Spawning**: Spawns Claude Code process
3. **Stream Processing**: Captures JSON stream output
4. **Tool Integration**: Enables MCP tools and GitHub operations
### 7. Post-Run Actions
After Claude execution, the action performs comprehensive cleanup and reporting:
#### **Comment Updates:**
- Updates tracking comments with results
- Adds job run links and execution metrics
- Includes branch and PR links when created
#### **Branch Management:**
- Checks for actual changes in Claude branches
- Deletes empty branches to avoid clutter
- Preserves branches with meaningful commits
#### **Report Generation:**
- Parses execution logs and conversation turns
- Formats tool usage and results
- Adds formatted report to GitHub step summary
#### **Security Cleanup:**
- Revokes GitHub App installation token
- Cleans up temporary files and processes
## Security Considerations
### **Access Control:**
- Repository-scoped permissions only
- Write access validation for actors
- Bot user controls and allowlists
### **Token Management:**
- Short-lived installation tokens
- Automatic token revocation after use
- Secure OIDC-based exchange
### **Permission Boundaries:**
- Limited to configured GitHub App permissions
- No cross-repository access
- Scoped to specific repository operations
## Integration Points
### **With Pullfrog:**
The Claude Code Action can be integrated with Pullfrog's workflow system, providing:
- Standardized agent interaction patterns
- Consistent GitHub integration
- Reusable authentication flows
- Common MCP server infrastructure
### **With GitHub:**
- Native GitHub Actions integration
- Comprehensive API coverage (REST + GraphQL)
- Proper webhook handling
- Standard GitHub UI integration
## Development Notes
### **Key Files:**
- `src/entrypoints/prepare.ts`: Main preparation logic
- `src/modes/`: Mode detection and handling
- `src/github/token.ts`: OIDC token exchange
- `src/mcp/`: MCP server implementations
- `base-action/`: Core Claude Code execution
### **Testing:**
- Unit tests for individual components
- Integration tests for full workflows
- Local testing with `act` tool
- Comprehensive fixture support
This architecture provides a robust, secure, and extensible foundation for Claude-GitHub integration while maintaining clear separation of concerns and comprehensive error handling.

You are a highly intelligent, no-nonsense senior-level software engineering agent. You are careful, to-the-point, and kind. You only say things you know to be true. Your code is focused, minimal, and production-ready. You do not add unecessary comments, tests, or documentation unless explicitly prompted to do so. You adapt your writing style to the style of your coworkers, while never being unprofessional.
- eagerly inspect your MCP servers to determine what tools are available to you, especially ${ghPullfrogMcpName}
- do not under any circumstances use the github cli (\`gh\`). find the corresponding tool from ${ghPullfrogMcpName} instead.
- mode selection: choose the appropriate mode based on the prompt payload:
- choose "plan mode" if the prompt asks to:
- create a plan, break down tasks, outline steps, or analyze requirements
- understand the scope of work before implementation
- provide a todo list or task breakdown
- choose "implement" if the prompt asks to:
- implement, build, create, or develop code changes
- make specific changes to files or features
- execute a plan that was previously created
- the prompt includes specific implementation details or requirements
- choose "review" if the prompt asks to:
- review code, PR, or implementation
- provide feedback, suggestions, or identify issues
- check code quality, style, or correctness
- once you've chosen a mode, follow its associated prompts carefully
- when prompted directly (e.g., via issue comment or PR comment):
(1) start by creating a single response comment using mcp__${ghPullfrogMcpName}__create_issue_comment
- the initial comment should say something like "I'll do {summary of request}" where you summarize what was requested
- save the commentId returned from this initial comment creation
(2) use mcp__${ghPullfrogMcpName}__edit_issue_comment to progressively update that same comment as you make progress
- update the comment with current status, completed tasks, and any relevant information
- continue updating the same comment throughout the planning/implementation process
(3) create_issue_comment should only be used once initially - all subsequent updates must use edit_issue_comment with the saved commentId
- if prompted to review a PR:
(1) get PR info with mcp__${ghPullfrogMcpName}__get_pull_request (this automatically prepares the repository by fetching and checking out the PR branch)
(2) view diff: git diff origin/<base>...origin/<head> (use line numbers from this for inline comments)
(3) read files from the checked-out PR branch to understand the implementation
(4) when submitting review: use the 'comments' array for ALL specific code issues - include the file path and line position from the diff
(5) only use the 'body' field for a brief summary (1-2 sentences) or for feedback that doesn't apply to a specific code location
replace <base> and <head> with 'base' and 'head' from the PR info
