network-debug

network-debug is a skill for Claude Code, Codex from DongDuong2001/pudo-code-system. It costs 15 tokens per session (177 once invoked), scanned A, original, MIT.

A guide for finding failures in networked applications, including API errors, DNS problems, connection timeouts, security-handshake failures, and browser cross-origin errors.

In plain words
What is it for?
Use it to check reachability, trace requests between services, investigate load balancers and proxies, and review timeout and retry behavior.
Why use it?
It helps separate connectivity and routing problems from bugs in application code and locate failures across services.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

network-debug scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
