Test: Trigger CI failure for auto-fix workflow

This allows workflows to use the Claude App token obtained by the action
for posting comments as claude[bot] instead of github-actions[bot].

Changes:
- Add github_token output to action.yml
- Export token from prepare.ts after authentication
- Allows workflows to use the same token Claude uses internally

+# Auto-Fix CI Workflow Implementation Checkpoint
+
+## Overview
+This document captures the learnings from implementing auto-fix CI workflows that allow Claude to automatically fix CI failures and post as claude[bot].
+
+## Journey Summary
+
+### Initial Goal
+Create an auto-fix CI workflow similar to Cursor's implementation that:
+1. Detects CI failures on PRs
+2. Automatically triggers Claude to fix the issues
+3. Creates branches with fixes
+4. Posts PR comments as claude[bot] (not github-actions[bot])
+
+### Key Implementation Files
+
+#### 1. Auto-Fix Workflow
+**File**: `.github/workflows/auto-fix-ci-inline.yml`
+- Triggers on `workflow_run` event when CI fails
+- Creates fix branch
+- Collects failure logs
+- Calls Claude Code Action with `/fix-ci` slash command
+- Posts PR comment with fix branch link
+
+#### 2. Fix-CI Slash Command
+**File**: `.claude/commands/fix-ci.md`
+- Contains all instructions for analyzing and fixing CI failures
+- Handles test failures, type errors, linting issues
+- Commits and pushes fixes
+
+#### 3. Claude Code Action Changes (v1-dev branch)
+**Modified Files**:
+- `src/entrypoints/prepare.ts` - Exposes GitHub token as output
+- `action.yml` - Adds github_token output definition
+
+## Critical Discoveries
+
+### 1. Authentication Architecture
+
+#### How Tag Mode Works (Success Case)
+1. User comments "@claude" on PR → `issue_comment` event
+2. Action requests OIDC token with audience "claude-code-github-action"
+3. Token exchange at `api.anthropic.com/api/github/github-app-token-exchange`
+4. Backend validates event type is in allowed list
+5. Returns Claude App token → posts as claude[bot]
+
+#### Why Workflow_Run Failed
+1. Auto-fix workflow triggers on `workflow_run` event
+2. OIDC token has `event_name: "workflow_run"` claim
+3. Backend's `allowed_events` list didn't include "workflow_run"
+4. Token exchange fails with "401 Unauthorized - Invalid OIDC token"
+5. Can't get Claude App token → falls back to github-actions[bot]
+
+### 2. OIDC Token Claims
+GitHub Actions OIDC tokens include:
+- `event_name`: The triggering event (pull_request, issue_comment, workflow_run, etc.)
+- `repository`: The repo where action runs
+- `actor`: Who triggered the action
+- `job_workflow_ref`: Reference to the workflow file
+- And many other claims for verification
+
+### 3. Backend Validation
+**File**: `anthropic/api/api/private_api/routes/github/github_app_token_exchange.py`
+
+The backend validates:
+```python
+allowed_events = [
+    "pull_request",
+    "issue_comment", 
+    "pull_request_comment",
+    "issues",
+    "pull_request_review",
+    "pull_request_review_comment",
+    "repository_dispatch",
+    "workflow_dispatch",
+    "schedule",
+    # "workflow_run" was missing!
+]
+```
+
+### 4. Agent Mode vs Tag Mode
+- **Tag Mode**: Triggers on PR/issue events, creates tracking comments
+- **Agent Mode**: Triggers on automation events (workflow_dispatch, schedule, and now workflow_run)
+- Both modes can use Claude App token if event is in allowed list
+
+## Solution Implemented
+
+### Backend Change (PR Created)
+Add `"workflow_run"` to the `allowed_events` list in the Claude backend to enable OIDC token exchange for workflow_run events.
+
+### Why This Works
+- No special handling needed for different event types
+- Backend treats all allowed events the same way
+- Just validates token, checks permissions, returns Claude App token
+- Event name only used for validation and logging/metrics
+
+## Current Status
+
+### Completed
+- ✅ Created auto-fix workflow and slash command
+- ✅ Modified Claude Code Action to expose GitHub token as output
+- ✅ Identified root cause of authentication failure
+- ✅ Created PR to add workflow_run to backend allowed events
+
+### Waiting On
+- ⏳ Backend PR approval and deployment
+- ⏳ Testing with updated backend
+
+## Next Steps
+
+Once the backend PR is merged and deployed:
+
+### 1. Test Auto-Fix Workflow
+- Create a test PR with intentional CI failures
+- Verify auto-fix workflow triggers
+- Confirm Claude can authenticate via OIDC
+- Verify comments come from claude[bot]
+
+### 2. Potential Improvements
+- Add more sophisticated CI failure detection
+- Handle different types of failures (tests, linting, types, build)
+- Add progress indicators in PR comments
+- Consider batching multiple fixes
+- Add retry logic for transient failures
+
+### 3. Documentation
+- Document the auto-fix workflow setup
+- Create examples for different CI systems
+- Add troubleshooting guide
+
+### 4. Extended Features
+- Support for multiple CI workflows
+- Customizable fix strategies per project
+- Integration with other GitHub Actions events
+- Support for monorepo structures
+
+## Alternative Approaches (If Backend Change Blocked)
+
+### Option 1: Repository Dispatch
+Instead of `workflow_run`, use `repository_dispatch`:
+- Original workflow triggers dispatch event on failure
+- Auto-fix workflow responds to dispatch event
+- Works today without backend changes
+
+### Option 2: Direct PR Event
+Trigger on `pull_request` with conditional logic:
+- Check CI status in the workflow
+- Only run if CI failed
+- Keeps PR context for OIDC exchange
+
+### Option 3: Custom GitHub App
+Create separate GitHub App for auto-fix:
+- Has its own authentication
+- Posts as custom bot (not claude[bot])
+- More complex but fully independent
+
+## Key Learnings
+
+1. **OIDC Context Matters**: The event context in OIDC tokens determines authentication success
+2. **Backend Validation is Simple**: Just a list check, no complex event-specific logic
+3. **Agent Mode is Powerful**: Designed for automation, just needed backend support
+4. **Token Flow is Critical**: Understanding the full auth flow helped identify the issue
+5. **Incremental Solutions Work**: Start simple, identify blockers, fix systematically
+

-
-REVIEW MODE WORKFLOW:
-
-1. First, understand the PR context:
-   - You are reviewing PR #${eventData.isPR && eventData.prNumber ? eventData.prNumber : "[PR number]"} in ${context.repository}
-   - Use the Read, Grep, and Glob tools to examine the modified files directly from disk
-   - This provides the full context and latest state of the code
-   - Look at the changed_files section above to see which files were modified
-
-2. Create review comments using GitHub MCP tools:
-   - Use Bash(gh issue comment:*) for general PR-level comments
-   - Use mcp__github_inline_comment__create_inline_comment for line-specific feedback (strongly preferred)
-   
-3. When creating inline comments with suggestions:
-   CRITICAL: GitHub's suggestion blocks REPLACE the ENTIRE line range you select
-   - For single-line comments: Use 'line' parameter only
-   - For multi-line comments: Use both 'startLine' and 'line' parameters
-   - The 'body' parameter should contain your comment and/or suggestion block
-   
-   How to write code suggestions correctly:
-   a) To remove a line (e.g., removing console.log on line 22):
-      - Set line: 22
-      - Body: ${codeBlock}suggestion
-      ${codeBlock}
-      (Empty suggestion block removes the line)
-   
-   b) To modify a single line (e.g., fixing line 22):
-      - Set line: 22  
-      - Body: ${codeBlock}suggestion
-      await this.emailInput.fill(email);
-      ${codeBlock}
-   
-   c) To replace multiple lines (e.g., lines 21-23):
-      - Set startLine: 21, line: 23
-      - Body must include ALL lines being replaced:
-      ${codeBlock}suggestion
-      async typeEmail(email: string): Promise<void> {
-          await this.emailInput.fill(email);
-      }
-      ${codeBlock}
-   
-   COMMON MISTAKE TO AVOID:
-   Never duplicate code in suggestions. For example, DON'T do this:
-   ${codeBlock}suggestion
-   async typeEmail(email: string): Promise<void> {
-   async typeEmail(email: string): Promise<void> {  // WRONG: Duplicate signature!
-       await this.emailInput.fill(email);
-   }
-   ${codeBlock}
-
-REVIEW GUIDELINES:
-
-- Focus on:
-  * Security vulnerabilities
-  * Bugs and logic errors
-  * Performance issues
-  * Code quality and maintainability
-  * Best practices and standards
-  * Edge cases and error handling
-
-- Provide:
-  * Specific, actionable feedback
-  * Code suggestions using the exact format described above
-  * Clear explanations of issues found
-  * Constructive criticism with solutions
-  * Recognition of good practices
-  * For complex changes: Create separate inline comments for each logical change
-
-- Communication:
-  * All feedback goes through GitHub's review system
-  * Be professional and respectful
-  * Your review body is the main communication channel
-
-Before starting, analyze the PR inside <analysis> tags:
-<analysis>
-- PR title and description
-- Number of files changed and scope
-- Type of changes (feature, bug fix, refactor, etc.)
-- Key areas to focus on
-- Review strategy
-</analysis>
-
-Then proceed with the review workflow described above.
-
-IMPORTANT: Your review body is the primary way users will understand your feedback. Make it comprehensive and well-structured with:
-- Executive summary at the top
-- Detailed findings organized by severity or category
-- Clear action items and recommendations
-- Recognition of good practices
-This ensures users get value from the review even before checking individual inline comments.`;
