Fix

Purpose

Resolve concrete bugs safely through structured diagnosis, minimal fixes, and verification.

This skill is for bug-fix execution when scope is clear and risk is manageable.

Scope Gate (Required Before Starting)

Use this skill only when all conditions below are true:

1. Concrete issue signal exists

   • Clear failing behavior, error, or regression is identified
   • Enough evidence exists to begin diagnosis (logs, stack trace, failing test, or reproducible steps)

2. Likely localized fix path

   • Issue appears constrained to a small area
   • No expected cross-system redesign or migration
