debugging-network-issues

debugging-network-issues is a Root-cause investigation skill for AI agents, published by daymade in the claude-code-skills repository on GitHub. Skillspace rates debugging-network-issues F (45/100) and the safety scan rated it risky; the rating is based on static analysis only.

Investigates network, streaming, and protocol failures with falsification-first layered experiments. Use for ECONNRESET, HTTP/2 RST_STREAM, SSE or long-polling stalls, fixed-time drops, CDN/proxy/CGNAT timeouts, client-side proxy/TUN misrouting, CNAME-rule surprises, certificate errors, generic throughput collapse where everything returns 200 but transfers crawl, or LAN identity/topology mysteries. Trigger phrases include "socket closed unexpectedly", "stream interrupted", "fails after N seconds", "works sometimes but not always", "upstream silent for X seconds", ERR_CONNECTION_CLOSED, SSL_ERROR_SYSCALL, UNKNOWN_CERTIFICATE_VERIFICATION_ERROR, and wrong-site certificate. Treat this as the general method and unknown-root-cause fallback. Use tunnel-doctor for known Tailscale/TUN/DNS/route/WSL-Docker conflicts and for a confirmed proxy exit/node/chain quality problem.
