SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the time-consuming guesswork of troubleshooting broken API integrations, where ambiguous status codes, authentication failures, and schema mismatches can stall development and debugging workflows for hours.

Core Features & Use Cases

  • Layered Diagnostic Workflow: Systematically walks through connectivity, TLS, authentication, request format, response parsing, and semantic validation to pinpoint the exact failing layer in the API request chain, eliminating guesswork.
  • Status Code & Pattern Playbooks: Provides targeted troubleshooting steps for common HTTP status codes (401, 403, 429, 5xx) plus built-in patterns for pagination, idempotency, and API contract validation to catch schema drift early.
  • Real-World Use Case: For a team integrating a third-party payment processing API, use this Skill to quickly diagnose 422 Unprocessable Entity errors from missing required fields, or resolve 429 rate limit issues with exponential backoff logic.

Quick Start

Use the rest-graphql-debug skill to diagnose why your POST request to the /api/v1/users endpoint is returning a 422 Unprocessable Entity error, and get a corrected curl command with all required fields included.

Frequently Asked Questions about rest-graphql-debug

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I debug REST API failures and isolate the exact failing layer?▼

To debug REST API failures, use a layered diagnostic workflow that tests connectivity, TLS, authentication, request format, and response parsing sequentially to isolate the exact failing layer in the request chain.

Why does my GraphQL endpoint return schema mismatch errors during integration?▼

GraphQL schema mismatch errors occur due to API contract validation failures or schema drift. Isolate the issue by validating the response parsing and semantic layers against the expected endpoint schema.

How do I fix HTTP 429 rate limiting and 401 authentication errors in Python requests?▼

Fix HTTP 429 rate limiting by implementing exponential backoff logic, and resolve 401 authentication errors by verifying credential handling and request formatting using status code-specific playbooks for Python requests.

What is the best way to generate curl commands for troubleshooting API endpoints?▼

The best way to generate curl commands for API troubleshooting is to use automated diagnostic workflows that output executable code snippets with corrected fields to test failed endpoint requests directly.

Does this API debugging approach handle webhook callback failures and pagination issues?▼

Yes, this API debugging approach handles webhook callback failures and pagination issues by providing built-in troubleshooting patterns to systematically diagnose these specific REST and GraphQL integration scenarios.

How do I securely debug APIs without exposing sensitive credentials in my code?▼

Securely debug APIs by applying built-in security guardrails designed for handling API credentials and sensitive response data, preventing accidental exposure of secrets during the HTTP troubleshooting process.
