refactor

A command for restructuring existing code while keeping its behaviour unchanged. Refactoring improves how code is organised and maintained.

In plain words
What is it for?
Use it to improve code structure, apply recognised design approaches, and clean up code for a specified task.
Why use it?
It helps make difficult or repetitive code easier to understand and change without intentionally altering its functionality.

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

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 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.

Origin

This is a copy

88% identical to refactor — 1 line 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.

Use the refactor agent to improve code structure and maintainability for: $ARGUMENTS. Apply clean code principles, design patterns, and best practices while preserving all functionality.

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.
