# Antigravity for Claude Code — hybrid SDLC Run the **Antigravity CLI (`agy`, Gemini)** as a second AI working alongside Claude Code. The organizing idea is **intelligent model routing across the SDLC**: keep judgement-heavy work on Claude (the frontier model) and route deterministic, high-volume work to Antigravity (cheaper, faster Gemini). Two AIs, one workflow. - **Claude = conductor / orchestrator** — requirements, architecture, the hard 20% (edge cases, integration, correctness), specs, tests/evals, final review. - **Antigravity = delegated agent** — a full terminal agent (file edits, terminal, subagents, MCP, web/Vertex AI Search) that executes well-specified work. This is **agentic engineering, not vibe coding**: the value is the structure around the model — routing, shared rules, verification gates — not raw generation. *Generation is solved; verification, judgement, and direction are the craft.* ## Two modes (pick per task) - **Conductor (sync, inline):** you're shaping something in real time; delegate a small, well-scoped chunk to agy mid-flow (e.g. "generate these tests"), use the result immediately. - **Orchestrator (async, multi-unit):** decompose a larger task into units, dispatch to agy (often with `--dir`, agentic, in parallel), then review and integrate. Best for migrations, bulk implementation against patterns, test suites. ## Division of labor across the SDLC Route each phase to the right model. This is the core policy. | SDLC phase | Ow...
