Use the CalendarDIFF MCP tools to inspect workspace state, create proposals, and manage low-risk approval tickets safely.
Use when changing GitHub remotes, deploying CalendarDIFF to the AWS host, syncing repo state to the server, or editing live host config such as nginx/.env. Read this before any GitHub→AWS release or host-level runtime change.
Use when changing CalendarDIFF semantic logic, review flows, canonical event state, route/docs/contracts cleanup, or other work that must stay aligned with PURPOSE.md, ENTITY_FIRST_SEMANTIC_SPEC.md, and the monolith runtime. Skip for purely deploy-only or cosmetic UI tasks.
