Bug Fix

Rigorous, staged bug fixing: understand the bug → trace root cause → design fix → implement → verify & regression check.

Quick start

Invoke with a bug report: /bug-fix the login button does nothing on mobile

Claude will ask your questioning mode and whether to enable Log Mode, then work through each stage — stopping for approval before applying any fix.

Core Principles

• Reproduce before fixing — never write a fix for a bug you haven't understood
• Trace to root cause — fix the cause, not the symptom
• Minimal, targeted fixes — prefer the smallest change that correctly addresses the root cause
• Regression safety — every fix can break something else; always verify it doesn't
• Track everything — use TodoWrite to track all stages and progress
• Log decisions — when Log Mode is on, record findings to plans/ per LOG.md
