## CORE CHECKLIST ⚡
□ Include only sections relevant to the project type (Code API vs. HTTP API)
□ Provide complete and runnable examples for HTTP APIs
□ Use signatures-only for Code API documentation (no implementation)
□ Document all public-facing APIs, not internal ones

## UNIFIED API DOCUMENTATION TEMPLATE

This template supports both **Code API** (for libraries/modules) and **HTTP API** (for web services). Include only the sections relevant to your project type.
