Knowledge: Teaching Antigravity Your Codebase
The knowledge base turns corrections into durable rules — agents that brief like teammates, not strangers.
Antigravity maintains a knowledge base for your workspaces: durable facts distilled from past tasks — conventions, quirks, decisions — retrieved automatically when a new task touches the same ground. When you correct an agent ('never edit the generated client; re-run codegen instead'), that correction can become a knowledge item every future agent loads.
Curate it the way you curated CLAUDE.md in Course 1: short, specific, non-obvious, and pruned occasionally for rot. Add explicit items for the rules you'd otherwise repeat — deploy quirks, do-not-touch zones, house test patterns, the flaky suite that needs --runInBand.
The compounding effect is the whole game. A fresh workspace needs a paragraph of briefing per task; a workspace with three weeks of curated knowledge needs a sentence. That delta is most of the difference between agents that feel magical and agents that feel like work.
