## What it is
aiofiles is an Apache-2.0 licensed Python library providing asynchronous file I/O for asyncio applications by delegating blocking file operations to a thread pool. It mirrors the standard Python file API with async/await support, including async tempfile and os interfaces.

## Use cases
- read and write files without blocking an asyncio event loop
- asynchronously iterate over lines in a file
- use tempfile in async Python code
- async access to stdin/stdout/stderr
- port blocking file IO code to asyncio

## When to choose
- you have an asyncio application doing local disk file IO
- you want an API identical to Python's built-in open but awaitable
- you need async tempfile or os.path operations

## When to avoid
- you need true non-blocking OS-level async IO rather than thread-pool delegation
- your application is not asyncio-based
- you need async network or remote file system access

## Facets
- artifact type: library
- maturity: stable
- function: file-system, concurrency, developer-tools
- domain: developer-tools, backend
- platform: python, cross-platform
- tags: asyncio, async-file-io, thread-pool, tempfile, automation
