A rigorous 4-phase methodology for gathering evidence, analyzing patterns, formulating hypotheses, and implementing proven fixes for software bugs.
This skill transforms an agent from 'guessing' at fixes to a systematic engineer. It enforces a disciplined approach to debugging that prevents regressions and ensures the root cause is truly understood before any code is changed.
Use this skill whenever you encounter a bug, test failure, or unexpected behavior. It is particularly critical when initial fix attempts have failed or when dealing with complex, intermittent errors.
Designed for high-capability coding agents such as Claude Code, Cursor, Codex, and other tool-enabled LLM environments.
A four-phase debugging methodology skill (Gather, Analyze, Formulate, Implement) with clear phase-gating and output templates. No scripts — pure prompt-driven workflow. Well-structured with anti-rationalization table and three-strike rule for failed hypotheses. Clean frontmatter with allowed-tools constraint.
No security concerns whatsoever — no network calls, no credentials, no destructive commands. Git commands are standard and safe. The skill is well-designed for its purpose.
