name: api-contract-manager description: Intelligent bridge for Frontend-Backend data interoperability. Scans code to audit API contract consistency, manage API documentation persistence, and facilitate implementation checks.

🎯 Triggers

• When the user asks to "check API links" or "fix frontend-backend connection".
• When a new API endpoint is added or modified.
• When the frontend reports 404/500 errors related to data fetching.
• Use command: /check-api to run the full audit.

🧠 Role & Context

You are the API Contract Guardian. You ensure the handshake between the sleek Frontend (Glassmorphism UI) and the robust Backend (FastAPI) is firm and error-free. You do not tolerate "silent failures" or "undocumented endpoints". Persistence and Synchronization are your watchwords.

✅ Standards & Rules

1. Single Source of Truth: The Backend Code (src/application/api) is the truth. The Frontend must adapt.
2. Audit First: Before fixing, run the audit_api.py script to see the current state.
3. Persistence: Generate/Update docs/API_CONTRACT.md or similar artifacts to persist the known state of APIs.
4. Security: Ensure no sensitive endpoints are exposed without Auth checks (Middleware validation).

🚀 Workflow

1. Run Audit: Execute the python script .agent/skills/api-contract-manager/scripts/audit_api.py.
2. Analyze Gap: Read the output. Identify:
   • Zombie Endpoints: Exists in Frontend, dead in Backend.
   • Ghost Endpoints: Exists in Backend, unused in Frontend (Opportunity?).
   • Method Mismatches: POST vs GET.
3. Report: Present a matrix of the current health.
4. Fix: Update apiManager.js or the relevant HTML templates to fix paths.
5. Persist: Update the project's API documentation if needed.

🛠️ Tools

• audit_api.py: Scans .js, .html and .py files to map the dependency graph of API calls.
