What problem does it solve? Developers working across the Threaded Stack monorepo need a single reference for the shared @tdsk/domain package, which defines the types, models, constants, and utilities used by the backend, proxy, admin, agent, and sandbox services. Without it, engineers must manually search 29 type files and 24 model classes to find correct imports and field definitions. ## Core Features & Use Cases - Type & Model Reference: Catalogs all enums, interfaces, and 24 model classes (Agent, ApiKey, Secret, Subscription, etc.) with their fields, computed properties, and methods. - Utility Documentation: Covers crypto functions (AES-256-GCM encryption, API key generation), permission checks (role hierarchy, canPerform), and Express API helpers (auth headers, Exception class). - Integration Guidance: Explains the two export entry points (index.ts for Node.js, web.ts for frontend-safe imports) and which services consume which exports. - Use Case: When adding a new endpoint to the backend, use this Skill to confirm the correct TRequest/TResponse types, the Exception.throw error pattern, and the permission check via canPerform before writing code. ## Quick Start Ask the AI to show the fields and methods of the Secret model and how to encrypt its value using the domain crypto utilities.
