event-loop-debugger

event-loop-debugger is a skill for Claude Code from Aitherium/awdk. It costs 51 tokens per session (1,710 once invoked), scanned A, original, no licence file.

A debugging guide for stalled asyncio event loops in Python services. An event loop is the scheduler that lets asynchronous Python code handle multiple tasks.

In plain words
What is it for?
Use it to detect, locate, and fix code that blocks an asyncio service, including on Python 3.14t.
Why use it?
A blocking system call or heavy CPU work can stop the loop from responding, and some usual debugging tools do not work on Python's free-threaded 3.14 build.

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

event-loop-debugger scanned grade A with 1 finding 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 yesterday.

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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
