Systematic Debugging

Quick Review

Exceptional debugging skill with comprehensive four-phase framework that enforces root cause investigation before fixes. The description clearly conveys the core principle (no fixes without investigation), making it easy for a CLI agent to know when and how to invoke this skill. Task knowledge is outstanding with detailed procedures, concrete examples, diagnostic patterns for multi-component systems, and clear decision trees (including the critical '3+ failed fixes = architectural problem' rule). Structure is excellent with logical flow from overview through phases to quick reference tables, though the document is somewhat lengthy. Novelty is strong—this framework meaningfully prevents the common AI tendency to jump to solutions, and the multi-layer diagnostic instrumentation guidance would require significant token expenditure to derive independently. The skill provides genuine value by codifying debugging discipline that saves time and reduces introduced bugs. Minor improvement possible: could separate some detailed examples into referenced files to make SKILL.md more scannable, but current structure remains clear and usable.
