Core Skill

Front door for working in a @*/core package — the domain heart of a hexagonal-architecture TypeScript monorepo built on the @efesto-cloud/* libraries, Inversify, pnpm workspaces, Biome, and nodenext module resolution.

This skill is self-contained. Every layer you need to touch — entity, value object, type/enum/dict, DTO, error, repository port, service port, use case, DI binding, persistence adapter, population — is documented in references/. Open the relevant reference when you start working on that layer.

When to use

Reach for this skill on any task touching the core package or its adapters:
