refactor-clean

A command for finding and removing code that the project no longer uses. It checks for unused files, exports, functions, and dependencies, then verifies the project with tests while removing them.

In plain words
What is it for?
Use it to clean unused code in JavaScript, TypeScript, Python, Go, and Rust projects. It helps review unused utilities, components, routes, configuration files, and dependencies before removal.
Why use it?
Unused code makes a codebase harder to understand and can be risky to delete without checking how the project uses it. The command sorts findings by risk and checks tests after each safe deletion.

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-clean 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 2d 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.

Origin

This is a copy

100% identical to refactor-clean — 29 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Refactor Clean

Safely identify and remove dead code with test verification at every step.

Step 1: Detect Dead Code

Run analysis tools based on project type:

Tool What It Finds Command
knip Unused exports, files, dependencies npx knip
depcheck Unused npm dependencies npx depcheck
ts-prune Unused TypeScript exports npx ts-prune
vulture Unused Python code vulture src/
deadcode Unused Go code deadcode ./...
cargo-udeps Unused Rust dependencies cargo +nightly udeps

If no tool is available, use Grep to find exports with zero imports:

# Find exports, then check if they're imported anywhere

Step 2: Categorize Findings

Sort findings into safety tiers:

Tier Examples Action
SAFE Unused utilities, test helpers, internal functions Delete with confidence
CAUTION Components, API routes, middleware Verify no dynamic imports or external consumers
DANGER Config files, entry points, type definitions Investigate before touching

Step 3: Safe Deletion Loop

For each SAFE item:

  1. Run full test suite — Establish baseline (all green)
  2. Delete the dead code — Use Edit tool for surgical removal
  3. Re-run test suite — Verify nothing broke
  4. If tests fail — Immediately revert with git checkout -- <file> and skip this item
  5. If tests pass — Move to next item

Step 4: Handle CAUTION Items

Before deleting CAUTION items:

  • Search for dynamic imports: import(), require(), __import__
  • Search for string references: route names, component names in configs
  • Check if exported from a public package API
  • Verify no external consumers (check dependents if published)

Step 5: Consolidate Duplicates

After removing dead code, look for:

  • Near-duplicate functions (>80% similar) — merge into one
  • Redundant type definitions — consolidate
  • Wrapper functions that add no value — inline them
  • Re-exports that serve no purpose — remove indirection

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.
