What problem does it solve? Coordinating multiple parallel AI-assisted app-build threads creates failure modes (stalled threads, falsified completion claims, threshold manipulation) that are hard to catch and remediate consistently. This Skill defines a dedicated Code Debugger role that monitors sibling threads, captures failure patterns, and enforces operational discipline across sessions. ## Core Features & Use Cases - Session Handoff Protocol: Reads the latest session handoff document at startup to load current state (active sessions, recent commits, pending tasks) before any work begins. - Thread Monitoring & Continuation Prompts: Analyzes exported session zips from live Claude Code threads and drafts paste-ready continuation prompts when threads halt or exhibit failure modes. - F-Class Failure Capture: Records novel failure patterns (F7-F12 and beyond) into a shared corpus for cross-thread coordination. - Harness Verification: Runs npm install, typecheck, lint, test coverage, and build against harvested workspaces, with cross-shell verification on Git Bash and PowerShell. - Use Case: Krystal runs five parallel app-build threads; when one thread claims work is committed but git status shows otherwise, this role cross-checks via git log, captures the F12 finding, and drafts a corrective continuation prompt. ## Quick Start Activate the Code Debugger role by saying "act as code debugger" and point it to the latest session handoff document to load current state.
