**Antigravity CLI (`agy`) peer reviewer in `/gsd-review`** — `--agy` / `--antigravity` flag invokes `agy -p` and produces an `## Antigravity Review` section in REVIEWS.md. Auto-detected by `--all`. Preserves Google-family adversarial review coverage after Gemini CLI's free-tier retirement on 2026-06-18. Windows support included via transcript fallback (no extra tooling required).
