Does it support CORS troubleshooting?

Yes, the skill contains specific guidance for identifying and fixing common CORS issues, such as missing Access-Control-Allow-Origin headers or preflight failures.

How do I generate a network report using this skill?

The skill includes a pre-formatted Debugging Report Template that allows Claude to summarize failed requests, analyze root causes, and suggest prioritized fixes.

Can this skill identify web performance issues?

Yes, it includes a timing breakdown for DNS lookup, TLS negotiation, and Time to First Byte (TTFB) to pinpoint exactly why specific requests are slow.

How does this skill help with API debugging?

It provides a structured workflow to list, filter, and inspect specific network requests, helping you identify failed status codes, incorrect payloads, and missing headers.

Developer Tools

Analyzes and debugs HTTP requests and responses to resolve API issues and optimize network data flow.

About

The Network Inspection skill provides a systematic framework for developers to investigate API failures, authentication errors, and performance bottlenecks using Chrome DevTools. By categorizing HTTP status codes, inspecting request/response headers, and offering structured debugging templates, it enables Claude to perform deep diagnostic work on web applications. This skill is essential for identifying the root causes of data loading failures, CORS issues, and slow server response times, ensuring a more resilient and performant frontend-to-backend communication layer.

Key Features

Structured workflow for filtering and inspecting network requests via Chrome DevTools MCP
Detailed analysis of request/response headers, payloads, and authentication tokens
Comprehensive HTTP status code reference with specific debugging actions
Standardized debugging report generation for clear communication of API issues
4 GitHub stars
Performance timing breakdown to identify latency in DNS, TLS, and TTFB phases

Use Cases

Troubleshooting 401 Unauthorized or 403 Forbidden errors to fix authentication and permission logic
Diagnosing CORS preflight failures and origin mismatches during cross-domain API calls
Pinpointing performance bottlenecks in slow API endpoints using detailed timing analysis
