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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00031 | $0.01456 |
| Opus 5.5 | $0.00012 | $0.00582 |
| Sonnet 5.5 | $0.00006 | $0.00291 |
| Haiku 4.5 | $0.00003 | $0.00146 |
Grade A, and why
code-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 2mo 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.

SKILL: Code Cleanup
Purpose: Dead code detection and removal using knip (recommended) or ESLint/TypeScript fallback Target: Coder Agent, cleanup commands
⚠️ EXECUTION DIRECTIVE
IMPORTANT: Execute ALL steps IMMEDIATELY and AUTOMATICALLY.
Core Philosophy: Auto-apply Low/Medium risk | High-risk: User confirmation | Safe flags: --dry-run, --apply | Verification after each batch
Quick Start
When to Use This Skill
- Remove unused import statements
- Detect and delete dead files (zero references)
- Clean up codebase after refactoring
Usage
MODE="${1:-files}" # imports|files|all
SCOPE="${2:-repo}" # repo|path=...
.cleanup-ignore Support
Create .cleanup-ignore file in project root:
# Core infrastructure
**/auth/**
**/database/**
**/*.config.*
# Entry points
**/index.ts
**/main.ts
# Generated files
**/generated/**
**/*.gen.ts
Loading order: Read .cleanup-ignore → Apply patterns → Exclude protected files
Step 1: Detect Dead Code
Detection Tools
Recommended: knip
npx knip # Full analysis
npx knip --reporter compact # Concise output
npx knip --fix # Auto-fix safe issues
Fallback: Standard tooling
grep -r "import.*from" src/ --include="*.ts" # Unused imports
find src/ -name "*.ts" -exec grep -l "{}" \; # Dead files
Dead File Detection Procedure
EXCLUDE="--glob '!*.test.ts' --glob '!*.spec.ts' --glob '!index.ts'"
rg --files $EXCLUDE src/ | while read file; do
refs=$(rg -c "from.*['\"]$file" src/ || echo 0)
[ "$refs" -eq 0 ] && echo "$file: 0 references"
done
Step 2: Risk Classification (4-Level)
| Risk | File Types | Action |
|---|---|---|
| SAFE | Tests (*.test.*), mocks, fixtures |
auto-remove |
| CAUTION | Utils, helpers, internal modules | auto-remove + prompt |
| WARNING | Components, services, hooks | tests pass first |
| DANGER | Auth, database, config, API routes | require --force |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 is a skill published in the GitHub repository changoo89/claude-pilot (20 stars, last pushed 8mo ago), licensed MIT. It adds 31 tokens to every session and 1,456 once invoked, about $0.0001 per session on Opus 5.5. 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.
