## What it does

The rule sets clean-code guidance for GitHub development. It asks Cursor to replace unexplained numeric values with named constants, choose names that show what variables, functions, and classes are for, and keep comments for intent or unusual behavior rather than obvious code.

It also favors short functions with a single responsibility. The rule targets files matching `**/*`, while its metadata sets `alwaysApply: false`, so Cursor does not mark it as active for every request. Install the file at `.cursor/rules/github-cursorrules-prompt-file-instructions.mdc`.

## Requirements
- Works with: GitHub

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/github-cursorrules-prompt-file-instructions.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/github-cursorrules-prompt-file-instructions.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/github-cursorrules-prompt-file-instructions.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/github-cursorrules-prompt-file-instructions.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/github-cursorrules-prompt-file-instructions.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/github-cursorrules-prompt-file-instructions.mdc

## When to use it
- replace hard-coded values with named constants
- rename variables and functions to show their purpose
- remove comments that repeat the code
- split multi-purpose functions
- make code easier to maintain

## Example prompts
- Review this file using the clean-code guidance and suggest focused changes.
- Replace unclear names and hard-coded values without changing behavior.
- Break this long function into smaller single-purpose functions.

Writing code is like giving a speech. If you use too many big words, you confuse your audience. Define every word, and you end up putting your audience to sleep. Similarly, when you write code, you shouldn't just focus on making it work. You should also aim to make it readable, understandable, and maintainable for future readers. To paraphrase software engineer Martin Fowler, "Anybody can write code that a computer can understand. Good programmers write code that humans can understand."

As software developers, understanding how to write clean code that is functional, easy to read, and adheres to best practices helps you create better software consistently.

This article discusses what clean code is and why it's essential and provides principles and best practices for writing clean and maintainable code.

What Is Clean Code?

Clean code is a term used to refer to code that is easy to read, understand, and maintain. It was made popular by Robert Cecil Martin, also known as Uncle Bob, who wrote "Clean Code: A Handbook of Agile Software Craftsmanship" in 2008. In this book, he presented a set of principles and best practices for writing clean code, such as using meaningful names, short functions, clear comments, and consistent formatting.

Ultimately, the goal of clean code is to create software that is not only functional but also readable, maintainable, and efficient throughout its lifecycle.

Why Is Clean Code Important?

When teams adhere to clean code principles, the code base is easier to read and navigate, which makes it faster for developers to get up to speed and start contributing. Here are some reasons why clean code is essential.

Readability and maintenance: Clean code prioritizes clarity, which makes reading, understanding, and modifying code easier. Writing readable code reduces the time required to grasp the code's functionality, leading to faster development times.

Team collaboration: Clear and consistent code facilitates communication and cooperation among team members. By adhering to established coding standards and writing readable code, developers easily understand each other's work and collaborate more effectively.

Debugging and issue resolution: Clean code is designed with clarity and simplicity, making it easier to locate and understand specific sections of the codebase. Clear structure, meaningful variable names, and well-defined functions make it easier to identify and resolve issues.

Improved quality and reliability: Clean code prioritizes following established coding standards and writing well-structured code. This reduces the risk of introducing errors, leading to higher-quality and more reliable software down the line.

Now that we understand why clean code is essential, let's delve into some best practices and principles to help you write clean code.

Principles of Clean Code

Like a beautiful painting needs the right foundation and brushstrokes, well-crafted code requires adherence to specific principles. These principles help developers write code that is clear, concise, and, ultimately, a joy to work with.

Let's dive in.

1. Avoid Hard-Coded Numbers

Use named constants instead of hard-coded values. Write constants with meaningful names that convey their purpose. This improves clarity and makes it easier to modify the code.

Example:

The example below uses the hard-coded number 0.1 to represent a 10% discount. This makes it difficult to understand the meaning of the number (without a comment) and adjust the discount rate if needed in other parts of the function.

Before:

def calculate_discount(price):  
  discount = price * 0.1 # 10% discount  
  return price - discount
```
