agy-staff

Hire Google's Antigravity CLI (agy) as a staffer for Claude Code and OpenAI Codex.

What & Why

agy-staff lets your senior agents delegate to agy, which ships fast Gemini 3.7 Flash. Five personas, one plugin name on both platforms: /agy:staffer (general-purpose), /agy:researcher, /agy:reviewer (code and plans/decisions), /agy:implementer, /agy:ask — plus a model-facing jobs skill that manages the background jobs (wait/status/result/cancel/continue/setup).

If you use Codex you know the feeling: GPT-5.6-Sol is slow even with fast mode on. Claude Code is quicker but still not fast, and Fable quota is scarce enough that you want it orchestrating subagents, not grinding through every survey and review itself. An agy worker gives you a fast lane — second opinions in seconds, research and reviews at Flash speed, scoped implementation handled off to the side while you keep moving. And where speed isn't the point, a second model family looking at the same code buys coverage and robustness your main agent can't give itself.

How

Type /agy: in Claude Code and the five personas are right there:

Same plugin in Codex, invoked with $agy:

Install

For humans

Step 1 — install the Antigravity CLI (official docs), then verify with agy --version (tested with v1.1.15; Node.js is also required):

curl -fsSL https://antigravity.google/cli/install.sh | bash

Step 2 — install the plugin into your harness:

claude plugin marketplace add keli-wen/agy-staff
claude plugin install agy@agy-staff

codex plugin marketplace add https://github.com/keli-wen/agy-staff
codex plugin add agy@agy-staff

Restart the harness afterwards so the skills load, then first run: /agy:ask "reply with OK" — ask is tool-free and works with zero setup.

[!IMPORTANT] There is no mandatory setup step. staffer, researcher, reviewer and implementer run unrestricted by default: agy can inspect the repo, run commands, and edit files. agy-staff keeps that practical with prompts that adapt to the current repo state. For example, when implementer starts in a dirty workspace, the companion tells agy which files already had changes and reminds it not to overwrite or deliver unrelated user work. If the task asks for a commit, push, or PR, agy can do that delivery; otherwise it leaves a working-tree diff for review. setup + --restricted is optional hardening for untrusted input — per run (--restricted) or as a per-repo default (setup --restrict review,research). setup dry-runs and asks before writing anything ("set up agy" triggers it); read the permission notes first — the allowlist is prefix-matched, applies machine-wide, and a restricted run can return less than an unrestricted one.

For agents

Paste this into any coding agent:

Read the raw text of https://raw.githubusercontent.com/keli-wen/agy-staff/master/docs/INSTALL_FOR_AGENTS.md (curl it — do not
work from a summary) and follow it to install and verify the agy-staff plugin for the harness you are running in.
Respond in the user's language.

Upgrade

Both harnesses install a copy, so a new version only reaches you when you pull it in yourself:

claude plugin marketplace update agy-staff && claude plugin update agy@agy-staff

codex plugin marketplace upgrade && codex plugin add agy@agy-staff  # then restart Codex

Both harnesses cache per version directory, so an upgrade lands only if the plugin version changed; restart the harness afterwards. If a fix does not show up, see upgrading — it has the force-refresh command.

CUJs

Invocation is always explicit — you type the command; the plugin never triggers itself on natural language. Examples use Claude Code's /agy:…; in Codex the same skills are $agy:….

reviewer is fully prompt-based: you describe the subject and agy gathers the evidence itself (gh pr view, git diff, reading the file) — there is no flag for handing it a diff. It has two flavors, routed by subject: code review (severity-ranked findings) and general review (a multi-angle challenge of a plan, design, or decision).

staffer also unlocks agy's native tools that no specialist persona covers — notably image generation (generate_image; verified on agy v1.1.15, a 1024×1024 PNG in ~30s).

ask answers in the same call. The other personas run as background jobs: the call returns a job id and prints the exact collect command (wait <id> --timeout <n>m); your agent runs that in the background — one wait per job — and delivers the result when it finishes.

Contributing

Contributions are welcome — issues, bug reports and pull requests all help.

Three things worth knowing before you open a PR:

• Run the tests: node --test tests/*.test.mjs. They are black-box tests against a fake agy (tests/fake-agy.mjs) in a throwaway repo and HOME, so they never hit the network or your real settings. Keep it that way — a test must never invoke the real binary.
• Docs come in pairs: README.md / README.zh-CN.md and docs/REFERENCE.md / docs/REFERENCE.zh-CN.md are kept in sync. Change one, change its counterpart.
• Behaviour lives in one place: companion/agy-companion.mjs holds all of it. The skills are thin shells that call it, and the prompt templates in templates/ carry the guardrails.

Adding a mode or a flag changes the public surface, so please open an issue first and we can agree on the shape.
