# Network Debugging Skill This skill focuses on tracing requests across distributed networks, resolving timeouts, and understanding protocol errors. ## When to use this skill - When external APIs or microservices return 5xx/4xx errors or timeouts. - When facing DNS resolution issues, TLS handshake failures, or CORS errors. - When debugging load balancer or reverse proxy routing. ## Guidelines - **Curl & Ping:** Use basic tools to ensure reachability before debugging application code. - **Trace IDs:** Utilize distributed tracing (OpenTelemetry, Jaeger) to identify exactly where a request failed in a multi-service architecture. - **Timeouts & Retries:** Verify that both read and connect timeouts are explicitly set, and retry logic is idempotent.
