Every "how do I do X in Y", every npm install , every dependency audit. The model fetches the registry JSON, reads it, summarizes for itself, and only THEN answers you.

And after six months in production with thousands of agents hitting it daily, I want to share what we've learned — including what's new in v0.9.0 that I shipped this morning. The 3 things every AI install costs you When your AI agent (Claude Code, Cursor, Windsurf, ChatGPT, whatever) suggests npm install <something> , three invisible costs land on your shoulders: 1.
