Specification

• App contract

  The contract an App publisher ships and a host may assume: Apps, Actions, params, auth, connections, health checks, categories and images.

• Composition

  How one call becomes a reusable operation, an entry point or a graph: Functions, Endpoints, Workflows, node types and triggers.

• Host & runtime

  The contracts that make an App portable across implementations: hook runtime, invocations, the registry and the engine.
