What problem does it solve? Production bugs get fixed sloppily — symptoms patched instead of root causes, fixes bundled with unrelated changes, and regressions discovered only after deploy. This Skill enforces a disciplined five-step workflow so live-system issues are reproduced, isolated, minimally fixed, regression-checked, and safely deployed. ## Core Features & Use Cases - Reproduction First: Requires a written reproduction recipe before any code is touched, ensuring the bug is actually understood. - Root Cause Isolation: Classifies failures into logic errors, data assumptions, state problems, integration failures, or config drift before writing the fix. - Smallest-Fix Discipline: Prevents scope creep by forbidding refactoring or adjacent improvements during the fix, with a path to surface larger cleanups separately. - Regression & Deploy Verification: Walks adjacent code paths, checks edge cases, deploys the fix alone, and confirms the bug is gone in the live environment. - Use Case: Users report that checkout fails intermittently in production. Use this Skill to reproduce the failure, trace it to a stale-cache state problem, apply a two-line fix, verify the payment and cart flows still work, and deploy the isolated commit. ## Quick Start Use the bug-fix skill to reproduce and fix the production issue where checkout fails for returning customers.
