Debug

Collaborating skills

• TDD: skill: tdd — write a failing test to pin down the bug before fixing (Phase 4)
• Refactor: skill: refactor — clean up code after the bug is confirmed fixed

The Core Principle

Random fixes waste time and create new bugs. Find the root cause before touching any code.

Never propose a fix without completing Phase 1. Symptoms are not root causes.

The Four Phases

Complete each phase before moving to the next.
