async-python-patterns

async-python-patterns is a skill for Claude Code from findscripter/everything-skills. It costs 108 tokens per session (2,009 once invoked), scanned A, original, no licence file.

A guide to writing asynchronous Python code with asyncio for I/O-heavy work. Async code can wait on network or file operations while other work continues, using async/await and an event loop.

In plain words
What is it for?
Use it to build concurrent request handlers, crawlers, batch operations, WebSocket clients, and background queues in Python.
Why use it?
It helps handle many API calls, WebSocket connections, crawler tasks, or queue jobs without fragile concurrency code. It covers timeouts, rate limits, cancellation, and structured error handling, but not CPU-heavy work.

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

async-python-patterns 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 today.

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.
