refactor-guardian

What problem does it solve?

Refactor operations can unintentionally alter behavior or break public interfaces; this skill provides guardrails that verify refactors are safe by construction.

Core Features & Use Cases

• Validates refactor intent and scope to prevent regressions.
• Enforces no-behavior-change contracts across code movement, module extraction, renaming, and architectural restructuring.
• Collects real artifacts (builds, tests, diffs) via terminal access and compares pre- and post-change behavior.
• Generates actionable remediation guidance and can write helper scripts to automate repetitive checks.
• Applies to large-scale restructuring before merges, providing a last-line safety net.

Quick Start

Run the guardian automatically during refactors to verify behavioral equivalence and public API stability.
