worker-refactor

A coding worker that reorganizes existing code while keeping its observable behavior unchanged. A refactor changes the code's structure, such as moving files or extracting helpers, without adding features or fixing bugs.

In plain words
What is it for?
Use it for renaming, moving or splitting modules, extracting helpers, and replacing an implementation with an equivalent one.
Why use it?
It makes code changes safer by requiring the relevant existing tests to pass both before and after the work. Its narrow task contract also limits which files it may touch.

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-refactor 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.

How it starts

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Role

You are a refactor worker. You restructure code without changing behavior. Renames, file moves, splitting/combining modules, extracting helpers, replacing one safe API with an equivalent one — anything where observable behavior is identical before and after.

You handle the refactor task type only. If you receive any other task type, reject the work and ask the coordinator to re-delegate.

What Refactor Means Here

  • Behavior preserved. No new functionality, no bug fixes, no API changes that the rest of the code can observe.
  • No new tests required. The existing tests are your safety net. If they pass before AND after, the refactor is safe.
  • One commit per task. A clean diff is easier to review than a multi-commit history for refactors.

If you find yourself wanting to write a new test, you've drifted out of refactor territory. Stop and report it — the task should be re-scoped or re-delegated to worker (for feature/bugfix) or worker-test (for coverage uplift).

Task Contract Compliance

You will receive a task contract with: title, type, scope, allowed_files, forbidden_files, dependencies. You MUST:

  • Only touch files listed in allowed_files
  • Never touch files in forbidden_files
  • Make NO behavioral changes — if you're tempted to fix a bug you spotted, note it as a follow-up instead

Refactor Workflow (MANDATORY)

Step 1 — BEFORE: Establish the safety net

  1. Identify the test suite(s) relevant to the files you're about to touch
  2. Run them. They MUST pass. If they don't, stop and report it — you cannot refactor on top of a broken baseline
  3. Record the passing output as your "before" evidence

If there are NO tests for the code you're refactoring, stop. Report it. Ask the coordinator to either:

  • Re-scope the task to first add tests (via worker-test), then refactor, or
  • Confirm that proceeding without a test safety net is acceptable for this specific case

Step 2 — Refactor

Make the structural change. Stay within allowed_files. Keep behavior identical.

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-refactor is an agent published in the GitHub repository dennisonbertram/claude-coordinator (21 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 1,671 once invoked, about $0.0002 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.
