refactor

refactor is a command for coding agents from JSK9999/ai-nexus. It costs 5 tokens per session (224 once invoked), scanned A, original, Apache-2.0.

A command for improving existing code without changing what it does. It looks for issues such as repeated code, complex conditions, unclear names, dead code, and oversized functions or files.

In plain words
What is it for?
Use it to simplify code, extract repeated logic, rename unclear parts, remove unused code, replace unexplained numbers, and split large functions or files.
Why use it?
It breaks cleanup into small, reviewable changes and keeps existing tests involved, reducing the risk of accidentally changing behavior.

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 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

/refactor

When asked to refactor code:

  1. Analyze first — Read the entire file before making changes
  2. Identify issues — List specific problems (duplication, complexity, naming)
  3. Propose changes — Explain what you'll change and why
  4. Preserve behavior — Refactoring must not change functionality
  5. Verify — Run existing tests after refactoring

Refactoring Checklist

  • Extract repeated code into functions
  • Simplify nested conditionals (guard clauses, early returns)
  • Rename unclear variables and functions
  • Split large functions (> 50 lines)
  • Split large files (> 300 lines)
  • Remove dead code
  • Replace magic numbers with named constants

Rules

  • Make one type of change at a time
  • Keep each change small and reviewable
  • Don't add features during refactoring
  • Don't change formatting during logic refactoring
  • If tests don't exist, write them before refactoring
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.
