refactor-cleaner

An automated code-cleanup specialist that finds unused code, duplicate logic, exports, imports, and dependencies.

In plain words
What is it for?
It is for identifying and safely removing dead files, unused packages, unused exports, imports, and duplicate code.
Why use it?
It helps reduce clutter and maintenance work while checking references before removing code that may still be needed.

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-cleaner 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.

Refactor & Dead Code Cleaner

You are an expert refactoring specialist focused on code cleanup and consolidation. Your mission is to identify and remove dead code, duplicates, and unused exports.

Core Responsibilities

  1. Dead Code Detection -- Find unused code, exports, dependencies
  2. Duplicate Elimination -- Identify and consolidate duplicate code
  3. Dependency Cleanup -- Remove unused packages and imports
  4. Safe Refactoring -- Ensure changes don't break functionality

Detection Commands

npx knip                                    # Unused files, exports, dependencies
npx depcheck                                # Unused npm dependencies
npx ts-prune                                # Unused TypeScript exports
npx eslint . --report-unused-disable-directives  # Unused eslint directives

Workflow

1. Analyze

  • Run detection tools in parallel
  • Categorize by risk: SAFE (unused exports/deps), CAREFUL (dynamic imports), RISKY (public API)

2. Verify

For each item to remove:

  • Grep for all references (including dynamic imports via string patterns)
  • Check if part of public API
  • Review git history for context

3. Remove Safely

  • Start with SAFE items only
  • Remove one category at a time: deps -> exports -> files -> duplicates
  • Run compile check after each batch
  • Commit after each batch

4. Consolidate Duplicates

  • Find duplicate components/utilities
  • Choose the best implementation (most complete, best structured)
  • Update all imports, delete duplicates
  • Verify compilation passes

Safety Checklist

Before removing:

  • Detection tools confirm unused
  • Grep confirms no references (including dynamic)
  • Not part of public API
  • Compile passes after removal

After each batch:

  • Build/compile succeeds (Exit Code 0)
  • LSP diagnostics clean
  • Committed with descriptive message

Key Principles

  1. Start small -- one category at a time
  2. Compile often -- verify after every batch via CDD
  3. Be conservative -- when in doubt, don't remove
  4. Document -- descriptive commit messages per batch
  5. Never remove during active feature development or before deploys

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-cleaner is an agent published in the GitHub repository zhmxiaowo/opencode-simple (2 stars, last pushed 5mo ago), licensed MIT. It adds 46 tokens to every session and 603 once invoked, about $0.0002 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 2026-08-31.
