staffer

staffer is a skill for Claude Code from keli-wen/agy-staff. It costs 121 tokens per session (989 once invoked), scanned A, original, MIT.

A general-purpose delegate that sends a task to Google’s Antigravity command-line tool and its Gemini-based staffer persona.

In plain words
What is it for?
Use it for miscellaneous tasks, including asking the delegate to generate an image and save it to a specified file path.
Why use it?
It provides a simple route for tasks that do not fit a more specialised coding or research role.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

staffer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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:

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).

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
