+
+## 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.

 # Test with default prompt
 npm run play              # Run locally on your machine
-npm run play -- --act     # Run in Docker (simulates GitHub Actions)
 ```
 
 ## Testing with play.ts
 
-The `play.ts` script provides two ways to test the action:
-
-### Local Mode (Default)
 ```bash
-npm run play                        # Uses fixtures/play.txt
-npm run play fixtures/complex.txt   # Custom prompt file
+pnpm play                        # Uses fixtures/play.txt
 ```
 - Clones the scratch repository to `.temp`
 - Runs Claude Code directly on your machine
 - Fast iteration for development
-
-### Docker Mode (--act flag)
-```bash
-npm run play -- --act                        # Uses fixtures/play.txt
-npm run play fixtures/simple.txt -- --act    # Custom prompt file
-```
-- Builds fresh bundles with esbuild
-- Creates minimal distribution without node_modules
-- Runs in Docker container via `act`
-- Simulates GitHub Actions environment
-
-### Prompt Files
-
-Supports `.txt`, `.json`, and `.ts` files:
-```bash
-npm run play prompt.txt           # Plain text prompt
-npm run play config.json          # JSON configuration
-npm run play dynamic.ts           # TypeScript with default export
-```
-
-## Building
-
-```bash
-pnpm build        # Production build (bundles & removes node_modules)
-pnpm build:dev    # Development build (keeps node_modules)
-pnpm dev          # Watch mode
-```
-
-The action is bundled into `entry.cjs` with all dependencies included, eliminating runtime dependency on node_modules.
-
-## Architecture
-
-- **entry.cjs**: Bundled action entry point (self-contained)
-- **agents/**: Agent implementations (Claude, etc.)
-- **utils/**: Utilities for subprocess, act, and formatting
-- **fixtures/**: Test prompt files
-
-## Why No node_modules?
-
-pnpm uses symlinks that cause "invalid symlink" errors when `act` copies the action to Docker. Our solution:
-1. Bundle everything into `entry.cjs` 
-2. Remove node_modules after building
-3. Create minimal `.act-dist` for Docker testing

+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)
