Every tool now returns a Go struct (apitypes.go) instead of a map, and typeschema.go derives the OpenAPI response schemas from those types by reflection (json, doc and enum tags), so the document cannot drift from what is sent. Text results are documented as text/plain, settings in answers use the typed settings schema, and edits answer with EditResponse. TestResponsesMatchTheirSchemas checks real responses against the generated schemas.
