Overview

This skill, 'Test First Bugs (Grade A)', is a security-tested data-ai skill for Claude AI. It enforces a disciplined bug-fixing workflow that prevents regression and parallelizes fix attempts. The skill guides users through a three-phase process: reproducing and documenting the bug, fixing it with subagents, and verifying the fix. It emphasizes writing a failing test as the first step in the process, followed by launching fix subagents, and finally, ensuring no regressions were introduced. The skill also provides a test naming convention and structure, along with a method for launching fix subagents and parallelizing fix attempts. It is particularly useful when a user reports a bug, describes unexpected behavior, or mentions an 'error', 'issue', or 'problem' in code. The skill's main goal is to facilitate a test-driven bug fixing workflow that helps developers identify and resolve bugs efficiently.
