using-live-documentation

Use BEFORE implementing, writing, configuring, or setting up ANY feature involving libraries, frameworks, or complex APIs - even before reading existing code. Fetches current documentation to ensure correct usage. Triggers on third-party libraries (such as react-query, FastAPI, Django, pytest), complex standard library modules (such as subprocess, streams, pathlib, logging), and "how to" questions about library usage. Do NOT use for trivial built-ins (such as dict.get, Array.map) or pure algorithms. Load this skill first to receive guidance on finding current documentation when implementing features, exploring code, or answering library-related questions.
