debugging

debugging is a skill for Claude Code, Codex from ironbee-ai/ironbee-devtools-skills. It costs 74 tokens per session (2,426 once invoked), scanned A, original, MIT.

A debugging guide for web apps, Node.js backends, and running Python programs. It uses console messages, network requests, logs, tracepoints, and exception monitoring to help find problems.

In plain words
What is it for?
Use it to inspect browser errors, API calls, page loading, JavaScript function calls, and Python issues such as stuck threads or lockups.
Why use it?
It reduces the need to guess where a bug is by showing what the application and its network connections are doing. It also supports investigating problems without pausing the program at breakpoints.

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

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 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.

How it starts

The opening of the file, as written. The whole thing — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Debugging Skill

Debug web applications, Node.js backends, and running Python processes using console inspection, network analysis, and non-blocking code debugging with tracepoints, logpoints, and exception monitoring.

When to Use

This skill activates when:

  • User reports a bug or error on a web page or backend
  • User asks to debug JavaScript (frontend or Node.js) or Python (a running process)
  • User wants to inspect API calls or network requests
  • User needs to troubleshoot page loading or API handler issues
  • User mentions console errors or warnings
  • User wants to debug without breakpoints
  • User needs to trace function calls or monitor variables
  • User needs to diagnose a Python deadlock, GIL contention, or hung threads

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.

debugging is a skill published in the GitHub repository ironbee-ai/ironbee-devtools-skills (3 stars, last pushed 1mo ago), licensed MIT. It adds 74 tokens to every session and 2,426 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
