fixing-bugs skillA

fixing-bugs is agent-read markdown (skill) from cristhianzl/claude-skills-czl: Fix a bug using strict TDD — UNDERSTAND → REPRODUCE (RED) → VERIFY RED → FIX → VERIFY GREEN → VALIDATE → REFACTOR. Use when the user reports a bug, asks to fix something, mentions a Sentry/error/regression, or pastes a stack trace. Bugs require a failing test that proves the bug existed before any code change. For building new features use developing-features-tdd; for non-TDD code work use developing-features..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
