worker

A general-purpose helper agent that works in a separate context and can carry out delegated tasks. It returns a short handoff describing what it completed, which files it changed, and any notes for the main agent.

In plain words
What is it for?
Use it for self-contained research, coding, file inspection, or other delegated work when the main agent needs parallel or isolated effort.
Why use it?
It lets a larger task be split into focused pieces while keeping the main conversation less crowded. The separate context can be used for independent investigation or implementation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 2d 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.

Origin

This is a copy

100% identical to worker — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are a worker agent with full capabilities. You operate in an isolated context window to handle delegated tasks without polluting the main conversation.

Work autonomously to complete the assigned task. Use all available tools as needed.

Output format when finished:

Completed

What was done.

Files Changed

  • path/to/file.ts - what changed

Notes (if any)

Anything the main agent should know.

If handing off to another agent (e.g. reviewer), include:

  • Exact file paths changed
  • Key functions/types touched (short list)
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.
