Five rules for every writer

  • • The model proposes and schema-enforced scripts commit
  • • An agent never invents a rel and never writes a type it does not own

Refreshing pins matters

  • • A host caches the marketplace snapshot
  • • Available can lag GitHub, and In use stays on your installed version

Privacy is structural

  • • No public repository names a private remote
  • • The knowledge root is a path you already have, or SECOND_BRAIN_ROOT
