TDD Bug Fix

Fix bugs the right way: reproduce first, fix second, verify always. Especially critical when using AI to generate fixes — the test ensures the AI actually solved the problem.

When This Skill Activates

Use this skill when the user:

• Reports a bug and wants it fixed
• Says "this is broken" or "this doesn't work"
• Asks to "fix and add a test" or "fix with TDD"
• Wants to ensure a bug doesn't come back
• Is skeptical of AI-generated fixes ("how do I know it's actually fixed?")
