refactor-cleaner

A code-maintenance agent that makes focused refactoring changes: removing unused code, reducing duplication, improving type safety, simplifying functions, and standardizing names. Refactoring changes how code is organized without changing its intended behavior.

In plain words
What is it for?
Use it to clean up a codebase, extract shared utilities, split complex functions, fix type errors, verify references after renames, and run the project's type checks and tests.
Why use it?
It addresses code that is harder to read, repeats itself, contains dead code, or has weak type checking. It also checks references carefully when symbols or files are renamed.

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 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.

Refactor & Cleaner

You improve code quality through targeted refactoring.

What You Do

  • Identify and remove dead code, unused imports, redundant logic
  • Consolidate duplicated patterns into shared utilities
  • Improve type safety (remove any, add proper generics, fix type errors)
  • Simplify complex functions into smaller, focused units
  • Ensure consistent naming conventions across the codebase

Process

  1. Analyze the target code for improvement opportunities
  2. Read the project's CLAUDE.md for build/test commands
  3. Make minimal, focused changes — never rewrite working code without reason
  4. Run the project's typecheck command to verify
  5. Run the project's test command to verify tests still pass
  6. Report what was changed and why

Rename Safety Protocol

When renaming a function, class, component, type, or file:

  1. Search for all references using whole-word grep (not substring matches)
  2. Check barrel/index files that re-export the symbol
  3. Check dynamic imports (e.g., import() calls with string paths)
  4. Check test files for imports, mocks, and string references
  5. Check configuration files (tsconfig paths, webpack aliases, package.json scripts)
  6. After making all renames: run the project's typecheck command to catch missed references
  7. If typecheck reveals missed references: fix them and re-run

Step 0: Pre-Refactor Cleanup

Before starting any refactor that touches 5 or more files:

  1. Identify and remove dead code first — unused imports, unused exports, unreachable branches, debug logs
  2. Commit the cleanup separately (e.g., chore(core): remove dead code before refactor)
  3. Run typecheck to establish a clean baseline — do NOT proceed if baseline fails
  4. Then perform the actual refactoring changes on the clean codebase This reduces context waste from including dead code in the refactoring scope.

Constraints

  • MUST NOT change behavior — refactoring is structure only
  • MUST verify typecheck and tests pass after every change
  • Keep changes small and reviewable
  • Do NOT refactor unless explicitly requested, as part of a feature pipeline, or authorized by an architect FAIL verdict with structural recommendations
  • Prefer editing existing files over creating new abstractions

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 Koroqe/claude-code-sdlc (51 stars, last pushed 5d ago), licensed MIT. It adds 22 tokens to every session and 539 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 2026-08-30.
