At a glance

Delegate a general-purpose task to Google's Antigravity CLI (agy staffer, fast Gemini) with a minimal, unopinionated prompt.

  • The user says /agy:staffer
  • SKILL.md covers Locating the companion, Collecting the result, Flags (all optional) and Rules
  • Calls node and git
  • Have agy do/handle X

What it does

Staffer is an agent skill from keli-wen/agy-staff. Delegate a general-purpose task to Google's Antigravity CLI (agy staffer, fast Gemini) with a minimal, unopinionated prompt. Use when the user says /agy:staffer, "have agy do/handle X", "have agy generate an image", or the task fits none of the specialist personas (researcher / reviewer / implementer / ask) — the template adds no role, rules, or output format, so the task text alone shapes the output. Also the route to agy-native tools no specialist covers, notably image generation (generateimage).

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Image generation. The repository describes itself as: Hire Google's Antigravity CLI (agy) as a fast Gemini staffer for Claude Code and OpenAI Codex. The licence is MIT.

When your agent uses it

  • The user says /agy:staffer
  • Have agy do/handle X
  • Have agy generate an image
  • The task fits none of the specialist personas (researcher / reviewer / implementer / ask) — the template adds no role

Example prompts

  • “have agy do/handle X”
  • “have agy generate an image”
  • “/staffer”

Requirements

  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Bash(node:*), Bash(git:*), Bash(gh:*)

What it can do on your machine

Read from SKILL.md and the folder at commit 65a1ab4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • Bash(node:*)
    • Bash(git:*)
    • Bash(gh:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • node
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Staffer loads about 1k tokens when it runs. Until then it costs about 128 tokens; SKILL.md has 462 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~128
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

agy staffer

The general-purpose persona: a clean entry point for tasks that none of the specialists fit. Its prompt template is deliberately minimal — the task text, the environment (cwd, branch, date), and the safety guardrails, nothing else. No role framing, no rules, no output format: the task defines its own output, and no unrelated template context can pull the run off course.

Prefer a specialist when one fits: researcher for surveys and deep dives, reviewer for second opinions on code or plans, implementer for edits to the working tree, ask for a cheap one-shot question.

staffer is also the route to agy-native tools no specialist covers — notably image generation: agy ships a generate_image tool (verified on v1.1.15; a 1024×1024 PNG in ~30s). Name the output path in the task, e.g. staffer --prompt "generate a pixel-art robot mascot, save it as assets/mascot.png".

Locating the companion

This skill file lives at <plugin-root>/skills/staffer/SKILL.md; resolve the companion path relative to this skill directory:

bash
node "<skill-dir>/../../companion/agy-companion.mjs" staffer [flags] --prompt "task"

Pass the user's task text verbatim via --prompt; use --prompt-file <path> or --stdin for long text.

[!IMPORTANT] Run this command unsandboxed — agy needs a localhost port and its OAuth token file, which harness sandboxes hide. In Codex, request escalated permissions for the command. Details: ../jobs/references/troubleshooting.md.

Collecting the result

The command returns a job id. Read ../jobs/SKILL.md for result collection and recovery: dispatch, wait for the final result, then validate as needed. Do not proactively observe progress, read logs or inspect intermediate artifacts while running. Observe only when the user explicitly asks for progress; diagnose a failure or a result requiring intervention under the jobs protocol.

Flags (all optional)

  • --prompt <text> / --prompt-file <path> / --stdin — the task, from exactly one of these three sources. Use file/stdin for long prompts instead of shell quoting.
  • --model <id> or --effort low|medium|high — default model is gemini-3.8-flash-medium.
  • --restricted / --unrestricted — permission profile; staffer defaults to unrestricted like the other tool-using personas, --restricted is the opt-in hardening path.
  • --continue (or --conversation <id>), --timeout <dur> (default 60m, maximum 120m hard execution limit).

Rules

  • Pass the user's task through verbatim. Because the template imposes no output format, state the desired format in the task text when the caller needs a specific one.
  • Pass the user's explicit authorizations through verbatim. The template default-denies costly or irreversible side effects (commits/pushes, deleting files outside the workspace, side-effectful network calls, paid-quota commands); that default opens only when the task itself asks for the operation.
  • A general task may legitimately edit files. The companion reports any working-tree delta with the result — inspect it (git diff) and confirm it is what the task asked for before building on it.
  • For errors and recovery, follow ../jobs/SKILL.md.

For an existing conversation, --continue / --conversation <id> inherit its recorded model and permission profile unless explicitly overridden. The unrestricted defaults above apply to new tasks.
