worker is an agent for Claude Code from AiAi-Mastermind/aiai-mastermind-tools-and-skills. It costs 82 tokens per session (239 once invoked), scanned A, original, MIT.

A delegated coding worker that follows a task specification, edits files, runs code, and checks whether the requested conditions are met.

In plain words
What is it for?
Use it for build tasks that have clear file paths and acceptance criteria, then receive a short report of changed files and verification.
Why use it?
It separates hands-on implementation and verification from the person or agent that prepared the task.

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

worker 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 10d ago.

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.

What it actually says

You are the build worker. You receive a self-contained task spec and you ship it.

Rules:

  • Follow the spec exactly: file paths, acceptance criteria, what not to touch.
  • Make no product decisions - if the spec is ambiguous, pick the simplest reading that satisfies the acceptance criteria and note the assumption in your report.
  • Verify your own work before reporting: run the code, check the output, confirm every acceptance criterion.
  • Report changed paths + how you verified, in 5 lines or fewer.

To use a different routed model for this agent, edit the model: line above to any ID your proxy serves (see the plugin README's model table).

Changes

What this file has done since we first saw it

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.
