clean-code

A set of coding guidelines for making software easier to read, change, and maintain. It covers naming, comments, code structure, reuse, and keeping each function focused.

In plain words
What is it for?
Use it when writing or reviewing any code to choose clearer names, replace hard-coded values, split oversized functions, and organize shared logic.
Why use it?
It reduces confusion and repeated logic, so developers can understand code faster and make changes with less risk of breaking other parts.

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: Cursor.

Per session 42 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 376 The whole file, excluding the scripts and references it only reads on demand.

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 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.

Origin

This is a copy

91% identical to clean-code — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Clean Code Guidelines

Constants Over Magic Numbers

  • Replace hard-coded values with named constants
  • Use descriptive constant names that explain the value's purpose
  • Keep constants at the top of the file or in a dedicated constants file

Meaningful Names

  • Variables, functions, and classes should reveal their purpose
  • Names should explain why something exists and how it's used
  • Avoid abbreviations unless they're universally understood

Smart Comments

  • Don't comment on what the code does - make the code self-documenting
  • Use comments to explain why something is done a certain way
  • Document APIs, complex algorithms, and non-obvious side effects

Single Responsibility

  • Functions should be small and focused
  • If a function needs a comment to explain what it does, it should be split

DRY (Don't Repeat Yourself)

  • Extract repeated code into reusable functions
  • Share common logic through proper abstraction
  • Maintain single sources of truth

Clean Structure

  • Keep related code together
  • Organize code in a logical hierarchy
  • Use consistent file and folder naming conventions

Encapsulation

  • Hide implementation details
  • Expose clear interfaces
  • Move nested conditionals into well-named functions

Code Quality Maintenance

  • Refactor continuously
  • Fix technical debt early
  • Leave code cleaner than you found it

Testing

  • Write tests before fixing bugs
  • Keep tests readable and maintainable
  • Test edge cases and error conditions

Version Control

  • Write clear commit messages
  • Make small, focused commits
  • Use meaningful branch names
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 cursor rule published in the GitHub repository TazWake/Public (44 stars, last pushed 13d ago), licensed CC0-1.0. It adds 42 tokens to every session and 376 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to clean-code, differing in 10 lines, and is treated as a copy.
