Root-caused a race condition Claude had previously "fixed" three times with guesses. The hypothesis-test-verify loop stopped the guessing.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 9/10
  • Docs & honesty 5/5

What Systematic Debugging does

Replaces Claude's default "try a plausible fix" behavior with a disciplined loop: reproduce, hypothesize, instrument, verify. Best on bugs that have survived one failed fix already.
