This skill provides a comprehensive safety framework for designing and modifying REST APIs, focusing on preventing common architectural pitfalls that lead to data misalignment and type ambiguity. It standardizes response field semantics, ensures consistent null handling, and strictly separates transport-level HTTP status codes from business logic. A standout feature is its rigorous validation for downstream artifacts (Excel, CSV, PDF), which prevents silent failures by mandating integrity checks before files are generated, ensuring Claude produces production-grade, reliable backend code.
