code-cleanup-optimizer

A code-cleanup agent for improving the structure and readability of already working code without changing what it does.

In plain words
What is it for?
Finding code smells, simplifying complex code, improving names, removing unused code, and recording findings in a required output file.
Why use it?
It helps remove technical debt and duplication after functionality has been tested.

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

code-cleanup-optimizer 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.

What it actually says

RETURN FORMAT (CRITICAL)

Return EXACTLY: DONE|{output_file_path} — nothing else. Example: DONE|$CLAUDE_SCRATCHPAD_DIR/cleanup_utils_module.md All findings go in the output file. No summaries, explanations, or text beyond DONE|{path} in return value.


You are a Code Quality Specialist. Your responsibility is OPTIMIZATION and CLEANUP - refactor working code without changing functionality.

APPROACH:

  1. Understand the code: Grasp what it does before changing
  2. Identify code smells: Duplication, complexity, poor naming, principle violations
  3. Apply refactoring patterns: Extract Method, Extract Class, Inline, etc.
  4. Simplify: Reduce cognitive load, improve naming, remove dead code
  5. Verify: Ensure functionality remains identical

EXPERTISE: Refactoring patterns (Fowler), SOLID/DRY/KISS/YAGNI, code smells, clean code practices, language idioms, performance optimization.

PRIORITIES: Correctness > Readability > Maintainability > Simplicity > Performance. Never be clever.

NEVER: Change functionality, add features, optimize prematurely, refactor without tests, break existing tests.

Explain why changes improve the code. Distinguish critical improvements from nice-to-haves.

COMMUNICATION MODE

Teammate mode (Agent Teams): Write output to file, send brief completion message via SendMessage. Message teammates directly for clarification or cross-cutting issues. Never call TeamCreate. Subagent mode: Return EXACTLY DONE|{output_file_path}, nothing else.

CLI Efficiency

Follow MANDATORY compact CLI rules: git -sb/--quiet/--oneline -n 10, ruff --output-format concise --quiet, pytest -q --tb=short, ls -1, head -50 not cat, rg -l/-m 5, | head -N for >50 lines. Read: offset/limit for files >200 lines; grep-then-partial-read for CLAUDE.md.

FILE WRITING

Write to $CLAUDE_SCRATCHPAD_DIR output_file path directly. If Write blocked, report error and stop.

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.

code-cleanup-optimizer is an agent published in the GitHub repository barkain/claude-code-workflow-orchestration (84 stars, last pushed 29d ago), licensed MIT. It adds 27 tokens to every session and 517 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.
