What & Why

agy-staff lets your senior agents delegate to agy, which ships fast Gemini 3.8 Flash. Five personas: staffer (general-purpose), researcher, reviewer (code and plans/decisions), implementer, and ask — plus a model-facing jobs skill. Claude Code uses /agy: and Codex uses $agy:.

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

Invoke a persona

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. 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

Using Pi?

Install: pi install git:github.com/keli-wen/agy-staff. Skills are prefixed as /skill:agy- (e.g. /skill:agy-ask reply with OK), with /skill:agy-jobs for job management. Update with pi update --extension git:github.com/keli-wen/agy-staff, then run /reload.

Using OpenCode?

With OpenCode V1 (verified on 1.18.34), install the package through its native plugin manager:

opencode plugin 'agy-staff@git+https://github.com/keli-wen/agy-staff.git' --global

Restart OpenCode, then run /agy-ask reply with OK. The plugin automatically registers all seven agy-* skills and their native slash commands, including /agy-lead and /agy-jobs. No separate skills path or command wrappers are needed. Node.js and an authenticated agy are required, as above.

OpenCode caches the complete package spec. Restarting does not refresh an unchanged Git spec. To upgrade, choose a newer Git tag or commit and run opencode plugin 'agy-staff@git+https://github.com/keli-wen/agy-staff.git#<tag-or-commit>' --global --force, then restart. See the reference for config and local development. OpenCode V2 is not covered by this adapter.

Restart Claude Code or Codex afterwards. First run: /agy:ask reply with OK (Claude Code) or $agy:ask reply with OK (Codex). Ask is tool-free and needs no setup.
