clean-code

clean-code is a skill for Claude Code, Codex from Amartuvshins0404/clean-code-skills. It costs 50 tokens per session (3,069 once invoked), scanned A, original, MIT.

A language-independent guide to writing, editing, reviewing, testing, and refactoring maintainable code. It focuses on clear intent, boundaries, naming, errors, concurrency, security, and avoiding code smells.

In plain words
What is it for?
Use it for new features, bug fixes, refactors, tests, reviews, scripts, SQL, infrastructure code, and user-interface components.
Why use it?
It gives practical checks for keeping changes understandable and safe across different languages and frameworks. It also helps avoid adding unnecessary layers or complexity.

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 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 353 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Clean Code

Clean code is code that makes its intent, behavior, boundaries, and failure modes easy for the next maintainer to understand and safely change.

This skill is language-agnostic. It does not mean "write Java everywhere" or "add object-oriented patterns everywhere." It means adapt clean-code principles to the project's language, framework, runtime, and local style.

For chapter-by-chapter depth, use references/chapter-map.md. It maps the full 17-chapter clean-code structure, concurrency appendix, legacy refactoring appendix, and heuristic cross-references into agent checklists.

For cross-canon principles drawn from peer-reviewed papers and other widely-cited engineering books (Parnas, Dijkstra, Knuth, Brooks, Hickey, Ousterhout, Hunt/Thomas, Martin, Fowler, GoF, McConnell, Software Engineering at Google), use references/canon.md. Reach for it when a decision concerns complexity, change, scale, optimization, or interface design and the chapter map is not enough.

When To Use

Use this skill for:

  • new features
  • bug fixes
  • refactors
  • tests
  • reviews
  • scripts and automation
  • SQL and data transformations
  • infrastructure as code
  • UI components
  • backend services
  • libraries and public APIs

Use a lighter version for trivial edits, but still avoid unrelated changes.

Operating Loop

1. Frame The Change

Before editing, identify:

  • the exact behavior or maintainability problem being solved
  • assumptions that could change the implementation
  • the smallest useful scope
  • the verification command or manual check that will prove the change

Ask a question only when ambiguity changes the implementation. Otherwise state the assumption and proceed.

2. Read Local Context

Inspect the nearby code before changing it:

  • naming vocabulary
  • module and file boundaries
  • error handling style
  • test style and fixtures
  • dependency patterns
  • formatting conventions
  • framework idioms

Local consistency beats generic preference.

3. Change The Smallest Slice

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.

clean-code is a skill published in the GitHub repository Amartuvshins0404/clean-code-skills (2 stars, last pushed 4mo ago), licensed MIT. It adds 50 tokens to every session and 3,069 once invoked, about $0.0003 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 2026-08-31.
