  Harness publishes JSON Schema draft-07 documents for the YAML entities its API accepts —
  pipelines, templates, triggers and input sets. These are the contract for the YAML
  BODIES the REST API and CLI take, which the OpenAPI itself only types as a string. The
  harness_schema MCP tool exists to hand an agent exactly these shapes before it writes a
  pipeline.
