Librarian
par iannuttall
Search up-to-date developer docs locally so AI agents stop guessing and writing bad code.
What it does

Tools

word,vector, andhybridmodes with library/version scoping. - library — Find a library by name and list available versions.
- get — Retrieve a specific document or slice by ID and line range.
