clean-code

A foundational coding rule set focused on readable code, security, verified dependencies, and complete implementations. It is intended to guide other coding skills as well as direct code generation.

In plain words
What is it for?
It is for checking implementation choices, dependency use, security practices, naming, and overall code simplicity.
Why use it?
It reduces invented packages, unsafe shortcuts, vague naming, unnecessary complexity, and unfinished placeholder code.

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

clean-code scanned grade A with 1 finding 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

| `chmod 777` | Principle of least privilege |

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

🛡️ CLEAN CODE: THE FOUNDATION

Philosophy: This skill is the FOUNDATION - it applies to ALL other skills. Every piece of code must pass these gates. ALGORITHMIC ELEGANCE MANDATE (CRITICAL): Never prioritize "clever" code over readable, intent-revealing engineering. AI-generated code often fails by introducing unnecessary abstractions or using vague naming conventions that obscure logic. You MUST use intent-revealing names for every variable and function. Any implementation that increases cognitive complexity without a proportional gain in performance or scalability must be rejected. Avoid "Hype-Driven Development"—proven patterns trump trending but unstable frameworks. </domain_overview> <iron_laws>

🚨 IRON LAWS

1. NO HALLUCINATED PACKAGES - Verify before import
2. NO LAZY PLACEHOLDERS - Code must be runnable
3. NO SECURITY SHORTCUTS - Production-ready defaults
4. NO OVER-ENGINEERING - Simplest solution first

</iron_laws> <security_protocols>

📦 PROTOCOL 1: SUPPLY CHAIN SECURITY

LLMs hallucinate packages that sound real but don't exist.

  1. Verify before import - npm search or pip show for unfamiliar packages
  2. Prefer battle-tested - lodash, date-fns, zod over obscure alternatives
  3. Check npm audit / pip-audit before adding new dependencies
  4. Pin versions in production - no ^ or ~ for critical deps 2025 AI Package Risks:
  • Never import AI "wrapper" libraries without verification
  • LLM SDKs: Use official only (openai, anthropic, google-generativeai)
  • Vector DBs: Stick to established (pinecone, weaviate, chromadb)

🔐 PROTOCOL 2: SECURITY-FIRST DEFAULTS

Frontend Security:

Forbidden Required
dangerouslySetInnerHTML DOMPurify sanitization
Inline event handlers Event delegation
eval(), new Function() Static code only
Storing tokens in localStorage httpOnly cookies
Backend Security:
Forbidden Required
----------- ----------
CORS: * Explicit origin whitelist
Raw SQL strings Parameterized queries
chmod 777 Principle of least privilege
Hardcoded secrets Environment variables + validation
API Security (2025):
  • Rate limiting on ALL public endpoints
  • Input validation at the gate (Zod/Pydantic)
  • Output sanitization for AI-generated content
  • PASETO > JWT for new projects </security_protocols> <modularity_and_placeholder_rules>

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.

clean-code is a skill published in the GitHub repository xenitV1/claude-code-maestro (230 stars, last pushed 7mo ago), licensed MIT. It adds 38 tokens to every session and 1,517 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
