This one gives Claude a methodical framework for tracking down bugs instead of letting it flail around. It pushes for reproduction first, then hypothesis-driven testing with binary search and instrumentation. The playbook covers distributed systems, performance issues, and production incidents. Honestly, the real value here is forcing a systematic approach when you're deep in a gnarly bug and tempted to just start changing things. It won't magically fix your code, but it'll keep Claude from suggesting random print statements and actually narrowing down root cause. Skip it if you don't have logs or can't reproduce the issue.
