safeguard

What problem does it solve?

This Skill creates essential safety measures before any code refactoring begins, preventing accidental data loss or breaking existing functionality.

Core Features & Use Cases

• Characterization Tests: Automatically generates tests that capture the current behavior of a module, ensuring you know exactly what to expect before changes are made.
• Boundary Markers: Adds comments to code to clearly delineate legacy code from new implementations and flag tightly coupled modules.
• Config Freezing: Preserves the exact state of configuration files (like tsconfig.json, .eslintrc, package-lock.json) at the time of the safeguard.
• Rollback Points: Creates a Git tag, providing a simple way to revert to the pre-refactoring state if needed.
• Use Case: Before refactoring a critical user authentication module, safeguard runs to create tests for all its functions, marks its boundaries, freezes the current project configuration, and creates a Git tag, ensuring you can safely proceed with the refactoring.

Quick Start

Run the safeguard skill on the 'user-auth' module to create a safety net before refactoring.
