About this skill

Systematic Debugging forces the assistant into a proper debugging loop: state the symptom, form hypotheses, design the smallest experiment that could falsify each one, run it, update beliefs. No guessing, no "try changing this and see". This skill exists because rushed fixes cause 80% of regressions. Slow is smooth; smooth is fast.

What it does

Explicit hypothesis tracking
Smallest-experiment design
Evidence log that survives context switches
Root-cause-first, symptom-second mindset
Refuses to ship a fix without a reproduction

Use cases

Investigate a flaky test that only fails in CI
Track down a memory leak across a long-running service
Find the real cause of a reported regression before guessing
