What problem does it solve? Writing HTTP contract tests against a deployed Insight stand requires knowing which persona session to use, which status codes each service actually returns, and how to keep the read-only stand clean — this Skill encodes all of those rules so tests assert real behavior instead of spec boilerplate. ## Core Features & Use Cases - Operation catalogue and coverage gate: Maintains a single catalogue of gateway-routed operations and reconciles observed requests against it to close endpoint coverage gaps. - Persona and status-code discipline: Guides the choice of caller session (admin operator, realm admin, other tenant, service client) and enforces per-test status assertions such as identity 404 versus analytics 403 for out-of-scope persons. - Scratch-resource policy and xfail handling: Enforces API-only row creation with tracked scratch names and leak detection, and marks known product defects as strict xfails rather than softened assertions. - Use Case: When adding a new /api/identity endpoint, use this Skill to register the operation, pick the right seeded persona, write one test per status code, and verify the coverage gate passes. ## Quick Start Write a contract test for the new identity endpoint under tests/stand/api/ following the stand-api-test conventions and run the coverage gate.
