cleanup

A command for finding and fixing technical debt, code smells, unnecessary complexity, and performance problems in a codebase.

In plain words
What is it for?
Use it to scan a project, prioritise cleanup, refactor incrementally, run tests, and report the changes.
Why use it?
It helps reduce maintenance problems such as duplicated code, unused code, outdated APIs, deep nesting, and inefficient operations.

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 15 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 377 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. 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 A, and why

cleanup 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

Cleanup & Refactor

Scan codebase for technical debt and code smells. Clean, refactor, optimize.

Scope

Code Smells:

  • Functions >20 lines → extract
  • Duplication (3+ occurrences) → DRY
  • Complexity (>3 nesting levels) → flatten
  • Unused code/imports/variables → remove
  • Commented code → delete
  • Magic numbers → named constants
  • Poor naming → clarify

Technical Debt:

  • TODOs/FIXMEs → implement or delete
  • Deprecated APIs → upgrade
  • Outdated patterns → modernize
  • Performance bottlenecks → optimize
  • Memory leaks → fix
  • Lint warnings → resolve

Optimization:

  • Algorithm complexity → reduce
  • N+1 queries → batch
  • Unnecessary re-renders → memoize
  • Large bundles → code split
  • Unused dependencies → remove

Execution

  1. Scan entire codebase systematically
  2. Prioritize by impact (critical → major → minor)
  3. Clean incrementally with atomic commits
  4. Test after every change
  5. Report what was cleaned and impact

Commit Strategy

One commit per logical cleanup:

  • refactor(auth): extract validateToken function
  • perf(db): batch user queries to fix N+1
  • chore: remove unused imports and commented code

Exit Criteria

  • No code smells remain
  • All tests pass
  • Lint clean
  • Performance improved (measure before/after)
  • Technical debt reduced measurably

Report: Lines removed, complexity reduced, performance gains.

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.

cleanup is a command published in the GitHub repository SylphxAI/coderag (12 stars, last pushed 7d ago), licensed MIT. It adds 15 tokens to every session and 377 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.
