refactor

refactor is a skill for Claude Code, Codex from softspark/ai-toolkit. It costs 29 tokens per session (1,439 once invoked), scanned A, original, Apache-2.0.

A guided workflow for restructuring existing code to improve its quality and maintainability without changing what it does.

In plain words
What is it for?
Useful for extracting functions or components, renaming symbols, moving code, removing unnecessary abstractions, simplifying logic, and running tests before and after changes.
Why use it?
It helps make refactoring changes in planned, reviewable steps while checking that existing behaviour remains intact.

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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/refactor-scan.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Refactor Code

$ARGUMENTS

Plan and execute code refactoring.

Usage

/refactor [target] [--pattern=<pattern>]

What This Command Does

  1. Analyzes target code
  2. Identifies refactoring opportunities
  3. Plans refactoring steps
  4. Executes with user approval

Refactoring Patterns

Pattern Description
extract-function Extract code block to function
extract-component Extract UI component
rename Rename symbol across codebase
move Move code to better location
inline Inline unnecessary abstraction
simplify Simplify complex logic

Safety Rules

  • Run tests before refactoring
  • Make atomic commits
  • Preserve behavior (no feature changes)
  • Run tests after each step
  • Don't mix refactoring with features

Output Format

## Refactoring Plan: [Target]

### Current State
- **Location**: [file:line]
- **Issues**: [what's wrong]

### Proposed Changes
1. [Change 1]
2. [Change 2]

### Impact Analysis
- **Files affected**: [count]
- **Risk level**: [Low/Medium/High]

### Test Coverage
- [x] Unit tests exist
- [ ] Integration tests needed

### Rollback

git revert [commit]

Approval Required

Before executing:

  • Plan reviewed
  • Tests passing
  • Backup created

Common Rationalizations

Excuse Why It's Wrong
"It works, don't touch it" Working code that's hard to maintain slows every future change
"We'll refactor it later" Later never comes — refactor when the pain is fresh and context is loaded
"It's too risky to change" That's exactly why it needs refactoring — risk compounds with complexity
"Just one more hack won't hurt" Each hack makes the next one easier to justify — break the cycle now
"We need to rewrite from scratch" Incremental refactoring is safer and delivers value continuously

READ BEFORE WRITE

This command analyzes and plans first. Execution requires explicit approval.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

refactor is a skill published in the GitHub repository softspark/ai-toolkit (169 stars, last pushed today), licensed Apache-2.0. It adds 29 tokens to every session and 1,439 once invoked, about $0.0001 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 2026-09-03.
