Tool Updater

Overview

Use this skill to refresh an existing CLI tool safely: research current best practices, compare against current implementation, generate a TDD patch backlog, apply updates, and verify CLI invocation.

When to Use

• Tool has broken require() paths or runtime errors
• Tool's CLI interface needs updating (new flags, changed behavior)
• Reflection flags stale or low-performing tool
• User asks to audit/refresh an existing tool

The Iron Law

Never update a tool blindly. Every refresh must be evidence-backed, TDD-gated, and integration-validated.
