SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps resolve integration gaps between frontend and backend systems by ensuring API calls, authentication, and data contracts match correctly. It reduces broken requests, inconsistent payloads, and user-access issues across the stack.

Core Features & Use Cases

  • API Endpoint Verification: Confirms frontend requests map to the correct backend routes, methods, and parameters.
  • Authentication Flow Coordination: Aligns token handling, login/logout behavior, and protected route access.
  • Error Handling & Debugging: Helps diagnose 404, 400, 401, and 500 issues with clear contract-based checks.
  • Use Case: A developer is seeing failed task loading after login and uses this Skill to verify the user ID path, bearer token handling, and response shape end to end.

Quick Start

Ask the assistant to compare your frontend request code against the backend API contract and identify any mismatched paths, headers, payload fields, or status-handling logic.

FAQPage Schema
How do I fix frontend API requests failing against backend routes?

Fix frontend API request failures by comparing endpoint paths, HTTP methods, and query parameters against the backend API contract to identify and resolve mismatches. This validation ensures frontend calls hit correct backend routes and return expected response schemas.

Why does my API return 401 errors after login when fetching user data?

API 401 errors after login often stem from mismatched bearer token handling or incorrect user-isolated access checks. This Skill aligns authentication flows by verifying token attachment, protected route access, and user ID path parameters end to end.

How do I debug API contract mismatches causing 400 and 404 errors?

Debug API contract mismatches by validating response schemas, payload fields, and endpoint paths against the backend definition. This Skill performs contract-based checks to diagnose 400, 404, and 500 issues caused by inconsistent data shapes or incorrect routing.

What is the best way to align authentication flows between frontend and backend?

Align authentication flows by verifying login and logout behavior, bearer token handling, and protected route access across the stack. This Skill coordinates token management to ensure frontend auth requests match backend API contract requirements for user-isolated access.

Can I use this to debug cross-origin request failures with task CRUD operations?

Yes, you can debug cross-origin request failures by validating endpoint paths, HTTP methods, and headers for task CRUD operations. This Skill checks cross-origin request configurations against backend API contracts to resolve integration failures.
