network-debugging

network-debugging is a skill for Claude Code, Codex from aj-geddes/useful-ai-prompts. It costs 25 tokens per session (494 once invoked), scanned A, original, MIT.

A process for finding connection, latency, and data-transfer problems between an application, browser, APIs, and servers. It examines requests, response codes, timing, security negotiation, and network conditions.

In plain words
What is it for?
Use it to inspect browser network requests, analyse loading waterfalls, test slower connections, and diagnose API communication problems.
Why use it?
It helps explain slow pages, failed or intermittent requests, cross-origin errors, SSL/TLS problems, and other issues that are difficult to locate from application code alone.

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-debugging 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-api.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Table of Contents

Overview

Network debugging identifies connectivity issues, latency problems, and data transmission errors that impact application performance.

When to Use

  • Slow loading times
  • Failed requests
  • Intermittent connectivity
  • CORS errors
  • SSL/TLS issues
  • API communication problems

Quick Start

Minimal working example:

Chrome DevTools Network Tab:

Columns:
  - Name: Request file/endpoint
  - Status: HTTP status code
  - Type: Resource type (xhr, fetch, etc)
  - Initiator: What triggered request
  - Size: Resource size / transferred size
  - Time: Total time to complete
  - Waterfall: Timeline visualization

Timeline Breakdown:
  - Queueing: Waiting in queue
  - DNS: Domain name resolution
  - Initial connection: TCP handshake
  - SSL: SSL/TLS negotiation
  - Request sent: Time to send request
  - Waiting (TTFB): Time to first byte
  - Content Download: Receiving response

Best Practices

✅ DO

  • Follow established patterns and conventions
  • Write clean, maintainable code
  • Add appropriate documentation
  • Test thoroughly before deploying

❌ DON'T

  • Skip testing or validation
  • Ignore error handling
  • Hard-code configuration values
Files

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
