A disciplined, test-first workflow for reproducing, triaging, and fixing software bugs while preventing regressions.
This skill provides a clear, disciplined workflow for diagnosing and fixing bugs in a codebase. It emphasizes reproducing failures reliably, localizing the causal layer, reducing to minimal repros, and implementing minimal root-cause fixes. The skill enforces a stop-the-line protocol to prevent compounding failures and mandates adding a regression test so the defect cannot reappear unnoticed. Practical commands and checklists guide issue creation, writing failing tests, running lint/type/test checks, and creating a focused PR.
Use this skill whenever a test, build, or lint fails, or when investigating reported defects and runtime errors. It is intended for reproduceable failures, flaky tests investigation, CI pipeline breakages, and any situation where a minimal, provable fix plus a regression test is required.
This skill is suitable for code-focused agents with Read/Edit/Write and Bash capabilities (tools that can run tests, edit files, and create commits/PRs).
