python-async-patterns SKILL.md skillA
python-async-patterns from aiskillstore/marketplace is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add aiskillstore/marketplace/python-async-patterns@git:20260113.222b7dePins git:20260113.222b7de in mdr.lock. Pin the fingerprint instead.

Python asyncio patterns for concurrent programming. Triggers on: asyncio, async, await, coroutine, gather, semaphore, TaskGroup, event loop, aiohttp, concurrent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python Async Patterns
Asyncio patterns for concurrent Python programming.
## Core Concepts
```python
import asyncio
# Coroutine (must be awaited)
async def fetch(url: str) -> str:
async with aiohttp.ClientSession() as session:
async with session.get(url) as response:
return await response.text()
# Entry point
async def main():
result = await fetch("https://example.com")
return result
asyncio.run(main())
```
## Pattern 1: Concurrent with gather
```python
async def fetch_all(urls: list[str]) -> list[str]:
"""Fetch multiple URLs concurrently."""
async with aiohttp.ClientSession() as session:
tasks = [fetch_one(session, url) for url in urls]
return await asyncio.gather(*tasks, return_exceptions=True)
```
## Pattern 2: Bounded Concurrency
```python
async def fetch_with_limit(urls: list[str], limit: int = 10):
"""Limit concurrent requests."""
semaphore = asyncio.Semaphore(limit)
async def bounded_fetch(url):
async with semaphore:
return await fetch_one(url)
return await asyncio.gather(*[bounded_fetch(url) for url in urls])
```
## Pattern 3: TaskGroup (Python 3.11+)
```python

How to install
mdr add aiskillstore/marketplace/python-async-patterns@sha256:c57e3c1292037588The line at the top of this page pins the label git:20260113.222b7de, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
