Antigravity Codebase Onboarding

Systematically analyze an unfamiliar codebase and produce a structured onboarding guide plus a starter AGENTS.md — the cross-tool standard instruction file used by Antigravity CLI (agy), Cursor, Claude Code, and other AI coding agents.

When to Use

• User asks to generate an AGENTS.md for a project
• User says "onboard me" or "walk me through this repo"
