MCP & harness repo maintainer

Maintain agent-first repos in the <workspace>/ family without copying the wrong shape into the wrong repo.

Core principle (all archetypes)

MCP and CLI are thin interfaces—APIs for agents and CI. Core contains the real logic, schemas, and registries. Adapters parse wire format (argv, MCP JSON-RPC); they delegate immediately.

Agents / CI  →  CLI ──┐
                      ├──► Core (logic, contracts, tests)
Agents / chat →  MCP ──┘

Full layering: core-and-interfaces.md. Parity: every MCP tool must call the same core entrypoint as its CLI twin (or CLI-only repos expose core via commands only).
