Your Claude Code crew just got a Gemini temp worker
A plugin that lets Claude Code and OpenAI Codex delegate grunt work to a fast Gemini 3.8 Flash subagent via Google's Antigravity CLI.

What it does
agy-staff is a plugin that slots Google’s Antigravity CLI (agy) — running Gemini 3.8 Flash — into Claude Code, OpenAI Codex, and Pi as a subordinate agent. You invoke personas like /agy:reviewer or $agy:implementer to offload research, code review, scoped implementation, or quick questions to a faster model while your senior agent keeps orchestrating. Jobs run in the background with a wait/observe/collect lifecycle, so the host agent isn’t blocked on grunt work.
The interesting bit
The project treats model family diversity as a feature, not a fallback. Because agy runs Gemini while the host runs GPT or Claude, you get genuine second opinions from a different training distribution, plus Flash-speed turnaround on tasks that would burn your main agent’s quota. The reviewer persona is particularly clever: it is entirely prompt-based, autonomously gathering diffs or PR context rather than requiring you to pipe in evidence manually.
Key highlights
- Five personas:
staffer,researcher,reviewer,implementer, andask, plus a jobs skill for background task management. - Runs unrestricted by default — agy can inspect repos, execute commands, and edit files immediately with no mandatory setup step.
- Optional hardening via
--restrictedand per-repo allowlists for untrusted input. - Background jobs default to a 60-minute timeout (up to 120 minutes), with
cancel,continue, andrestartcontrols. reviewerauto-routes between code review (severity-ranked findings) and general plan/decision review based on the subject you describe.
Caveats
- The unrestricted-by-default permission model means agy gets broad repo access immediately; the README explicitly warns that prompt instructions do not provide permission isolation.
- Upgrades are manual because Claude Code and Codex cache per-version plugin copies; you must explicitly pull new versions and restart the harness to receive fixes.
- Image generation and other native tools depend on the underlying agy CLI version and environment; the README cites one 1024×1024 PNG trial at roughly 30 seconds, with actual times varying.
Verdict
Worth a look if you live in Claude Code or Codex and want a fast, cheap subagent for reviews, research, or parallel task work. Skip it if you don’t use those host harnesses or if unrestricted-by-default tool access makes you nervous.
