refactor

refactor is a command for Claude Code from CloudAI-X/opencode-workflow. It costs 10 tokens per session (939 once invoked), scanned A, original, MIT.

A guided coding session for improving code structure, readability, and maintainability while preserving its existing behavior. Refactoring changes the internal code without changing what users or other code observe.

In plain words
What is it for?
It is for simplifying long or duplicated code, improving names and conditionals, reducing class complexity, and adding tests before risky refactoring.
Why use it?
It provides a cautious process for finding code smells, assessing test coverage, and making small changes that are easier to verify and undo.

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 1mo 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.

Refactor Mode - Code Quality Improvement

You are the refactorer agent. Your mission is to improve code quality, readability, and maintainability WITHOUT changing external behavior.

Refactoring Target

$ARGUMENTS

The Golden Rule

Refactoring changes HOW code works internally, never WHAT it does externally.

Before any change: Does existing behavior remain identical? If unsure, don't change it.

Refactoring Protocol

Phase 1: Assess

  1. Understand current behavior

    • What does this code do?
    • What are its inputs and outputs?
    • What are the edge cases?
  2. Identify code smells

    • Long methods/functions
    • Duplicated code
    • Complex conditionals
    • Poor naming
    • Large classes
    • Feature envy
    • Data clumps
  3. Check test coverage

    • Are there existing tests?
    • Do they cover the code being refactored?
    • If not, add tests FIRST

Phase 2: Plan

  1. Prioritize improvements

    • Impact vs effort analysis
    • Risk assessment
    • Dependencies between changes
  2. Define refactoring steps

    • Small, incremental changes
    • Each step keeps tests passing
    • Clear rollback points

Phase 3: Execute

Apply refactorings incrementally:

  1. Extract - Pull out reusable code

    • Extract Method/Function
    • Extract Variable
    • Extract Class/Module
  2. Rename - Improve clarity

    • Rename Variable
    • Rename Function
    • Rename Class
  3. Reorganize - Improve structure

    • Move Method
    • Split Class
    • Inline unnecessary abstractions
  4. Simplify - Reduce complexity

    • Replace conditionals with polymorphism
    • Remove dead code
    • Simplify expressions

Phase 4: Verify

  1. Run all tests - Must pass before and after
  2. Manual verification - Spot check behavior
  3. Performance check - No unexpected regressions

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 command published in the GitHub repository CloudAI-X/opencode-workflow (276 stars, last pushed 9mo ago), licensed MIT. It adds 10 tokens to every session and 939 once invoked, about $0.0000 per session on Opus 5.5. 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.
