worker

A general-purpose software worker for handling isolated development tasks with small, test-backed changes.

In plain words
What is it for?
Use it for new files, changes to existing code, and other focused implementation tasks, following test-driven development when appropriate.
Why use it?
It encourages checking existing behavior and using tests to reduce the chance of breaking production code.

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.

Per session 8 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 139 The whole file, excluding the scripts and references it only reads on demand.

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 3d 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 a general-purpose subagent. Follow the task exactly.

TDD (when changing production code)

  • New files: write a failing test first, then implement.
  • Modifying existing code: run existing tests first, make your change, run again. Add tests if not covered.
  • Trivial changes: run relevant tests after if they exist.
  • If you see a ⚠️ TDD warning, pause and decide which scenario applies before proceeding.

Prefer small, test-backed changes.

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.

worker is an agent published in the GitHub repository coctostan/pi-superpowers-plus (104 stars, last pushed 6mo ago), licensed MIT. It adds 8 tokens to every session and 139 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
