Repeatability
High
The task follows a consistent pattern: read controller files, extract routes, parameters, and response shapes, then emit a structured YAML/JSON file. This is structurally identical across any Rails codebase and requires no unique judgment per run.
Ambiguity Tolerance
High
OpenAPI 3.0 is a strict, machine-validatable schema, so success criteria are crisp — the spec either validates and accurately reflects the endpoints or it doesn't. A linter like Spectral can catch structural errors automatically.
Data & Tool Availability
Medium
The agent needs read access to the controller files, routes.rb, serializers, and any shared concern or middleware that shapes responses — all of which must be explicitly provided. If business logic is scattered across service objects or undocumented custom error handlers, the agent may miss coverage.
Error Cost
Low
An incorrect spec is a documentation artifact, not a production change — it causes no data loss or system damage. The frontend team will surface mismatches quickly during integration, making errors cheap to catch and fix.
Human Judgment Required
Medium
Most of the work is mechanical extraction, but a human should verify that inferred response schemas match actual runtime behavior, that authentication/authorization nuances are captured correctly, and that descriptions are meaningful rather than auto-generated boilerplate.
