API Contract Auditor
Audits API contracts and service boundaries to prevent layer leakage, entity exposure, and inconsistent error patterns.
The ln-643-api-contract-auditor is a specialized L3 worker designed to enforce architectural integrity at the service boundary. It automatically scans your codebase for common anti-patterns like ORM entities leaking into API responses, HTTP-specific types cluttering domain logic, and inconsistent error handling contracts. By providing a structured analysis with scores for compliance, completeness, quality, and implementation, it helps developers maintain a clean separation of concerns and production-ready API designs using specialized MCP tools for deep code symbol analysis.
