System Documentation

What problem does it solve?

This skill helps teams reverse-engineer specifications from legacy systems where documentation is missing, turning opaque code into clear contracts.

Core Features & Use Cases

  • Extracts API contracts, data schemas, and behavioral rules from code, tests, and UI flows.
  • Produces a structured set of spec files (system context, API contracts, feature specs) to guide refactoring and maintenance.
  • Handles evidence-driven inference and explicitly marks unknowns when evidence is insufficient.

Quick Start

Run the legacy-specifier on a repository to generate structured spec artifacts from existing code.
