Troubleshooting Regression

Use this skill when the framework appears stale, stuck, or regressed and you need deterministic diagnosis plus fix verification.

When to Use

• Claude debug sessions stall after spawning agents.
• Hooks block expected actions unexpectedly.
• Memory/search/token-saver enforcement appears inconsistent.
• A regression needs a repeatable reproduction and validation run.

Iron Law

Do not declare a regression fixed without:

1. reproducible trigger prompt,
2. trace evidence from pnpm trace:query,
3. hook/tool evidence from debug logs,
4. targeted test pass for touched scope.
