About this skill
Your agent stops designing APIs by vibes. This skill enforces a fixed contract: resource naming, correct status codes, a standard pagination envelope, a fixed error shape, versioning strategy, and idempotency where money moves.
- Includes a bad-to-default worked example so the agent sees the target, not just rules
- Auth conventions: opaque bearer tokens, scope in the token, sane expiry/refresh
- Flags the design smells that become breaking changes later
Works with Claude Code, Cursor, Codex, Copilot, and Gemini — standard SKILL.md format.
