Audit Type Ownership
Audits TypeScript type ownership and boundary placement to prevent architectural leakage and maintain clean repository structure.
The Audit Type Ownership skill is designed for developers managing complex TypeScript monorepos to maintain strict layered architecture. It systematically scans packages for misplaced or duplicated types, identifies leakage between query and service layers, and monitors root export surfaces. By leveraging a heuristic inventory script and comparing findings against defined architectural specs, it helps categorize types into contracts, query layers, or service layers, ensuring that internal logic and public-facing DTOs remain properly encapsulated and correctly located.
