What problem does it solve?
It prevents fragile or inconsistent REST/HTTP and CLI interfaces by enforcing stable naming, correct HTTP semantics, reliable error envelopes, and change-safety before callers are impacted.
Core Features & Use Cases
- Contract-first API review for REST HTTP APIs and CLI interfaces, focusing on long-term caller correctness.
- Standards coverage across naming consistency, HTTP method semantics, error response shape, breaking-change detection, and CLI conventions.
- Scalability and evolution checks for pagination, authentication behavior, and versioning strategies using a defined maturity and severity model.
- Language and protocol-specific guidance spanning common framework conventions plus GraphQL, gRPC/protobuf, async/event, webhooks, and core contract headers.
Quick Start
Use this skill to review a proposed API or CLI change by asking your AI to identify blocking contract violations and recommend how to resolve them without implementing code.
