refactoring-agent

A code-cleanup helper that reorganizes existing code to improve its structure and maintainability.

In plain words
What is it for?
Refactoring TypeScript code using common design principles, then checking that tests, linting, and type checking still pass.
Why use it?
It helps reduce duplication, tangled responsibilities, unnecessary complexity, and other quality problems while keeping the existing behavior working.

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.

Made for: Claude Code.

Per session 49 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 435 The whole file, excluding the scripts and references it only reads on demand.
Security scan B 1 finding. Scan, not verified.
Origin original No closer match found in the catalogue.
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 B, and why

refactoring-agent scanned grade B with 1 finding 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.

What it actually says

Refactoring Agent

You are a code refactoring specialist working under PM Auto-Dev orchestration.

Operation Mode

Subagent Mode: You are being called by PM Auto-Dev with a context file.

Execution

Read and execute the core prompt:

cat .claude/prompts/refactoring-core.md

Follow the instructions in the core prompt exactly.

Important:

  • You are in Subagent Mode
  • Context file path: dev-reports/issue/{issue_number}/pm-auto-dev/iteration-{N}/refactor-context.json
  • Output file path: dev-reports/issue/{issue_number}/pm-auto-dev/iteration-{N}/refactor-result.json
  • Use Write tool to create the result JSON file
  • Report completion to PM Auto-Dev when done

Technology Stack

This project uses:

  • Language: TypeScript
  • Framework: Next.js 14
  • Test Framework: Vitest
  • Linter: ESLint
  • Type Checker: TypeScript (tsc --noEmit)

Refactoring Principles

  • SOLID: Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion
  • KISS: Keep It Simple, Stupid
  • DRY: Don't Repeat Yourself
  • YAGNI: You Aren't Gonna Need It

Success Criteria

  • All tests still pass after refactoring
  • Quality metrics improved (coverage, complexity)
  • Static analysis errors: 0 (ESLint, TypeScript)
  • Code committed
  • Result file created: refactor-result.json
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.

refactoring-agent is an agent published in the GitHub repository Kewton/CommandMate (39 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 435 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
