Asyncio is cooperative — one blocking call freezes the entire event loop. Most "asyncio is slow" stories are actually "we accidentally called a synchronous function inside a coroutine." This catalogs the traps.
Python Asyncio Pitfalls is a community-contributed Claude Code skill in the languages sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/python-asyncio-pitfalls/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when debugging asyncio event-loop hangs, blocking calls inside coroutines, asyncio.gather vs TaskGroup choice, cancellation handling, structured concurrency, mixing sync and async, run_in_executor decisions, asyncio task lifetimes, "Task was destroyed but it is pending" warnings, or async context manager bugs.
The Python Asyncio Pitfalls Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 94,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
