## Code Review: PASS
### Feedback Addressed - Auto-Submit Approach Implemented
The worker addressed the architectural concern and implemented the suggested "auto-submit on PR URL update" approach instead of adding a new MCP tool.
### Changes Made
1. **Modified `handle_update_ticket`** (`app/controllers/api/v1/mcp_controller.rb`)
- When PR URL is added to ticket in `in_progress` status
- Automatically transitions to `pending_audit`
- Automatically marks agent as `idle`
- Returns `auto_submitted: true` flag
2. **Updated worker-workflow skill** (`.claude/skills/worker-workflow/SKILL.md`)
- Explains auto-submit behavior
- Removes need for manual `transition_ticket` and `mark_idle` calls
- Updates workflow diagram
3. **Removed the new MCP tool** - No `submit_for_review` tool added (simplification!)
### Benefits of This Approach
- ✅ **Simpler**: Uses existing `update_ticket` tool
- ✅ **No new MCP endpoint**: Reduces complexity
- ✅ **Automatic**: Workers just add PR URL, system handles the rest
- ✅ **Solves context overflow**: No manual steps to remember
### Test Results
- 582 examples, 1 failure (pre-existing UI issue, unrelated)
- MCP controller logic is straightforward and safe
### Recommendation: PASS
This is a cleaner solution that reduces complexity while solving the same problem.
