# Rules

> Create and manage custom review rules through CodeAnt AI Dashboard

These rules extend CodeAnt's default bug and security detection with company-specific coding practices, naming conventions, and standards.

## Accessing Dashboard Rules

Navigate to your Dashboard settings:

1. Go to [app.codeant.ai/settings/ai-rules](https://app.codeant.ai/settings/ai-rules)
2. Select **Rules** from the dropdown menu
3. Click **Add New** to create a new custom rule

## Creating Rules

### Step 1: Select Repositories

Choose which repositories should apply this rule:

* Use the search bar to find specific repositories
* Select multiple repositories using checkboxes
* All selected repositories will receive the same rule

### Step 2: Configure Rule

**Rule Description** (Required)

* Provide a clear, specific description of what this rule enforces
* Explain the reasoning behind the rule for team clarity

**File Patterns** (Required)

* Specify which files this rule applies to using glob patterns
* Click **Add** to include multiple patterns
* Use minimatch syntax for pattern matching

## Rule Categories

### Code Quality Rules

**No Console Logs in Production:**

```
Description: "Never use console.log statements in production code. Use proper logging services instead. This prevents sensitive data leaks and improves performance."

File Patterns:
- src/**/*.js
- src/**/*.ts
- src/**/*.jsx
- src/**/*.tsx
- !**/*.dev.js
- !**/*.test.*
```

**Function Complexity Limits:**

```
Description: "Functions should not exceed 50 lines of code. Break down complex functions into smaller, more maintainable pieces."

File Patterns:
- src/**/*.js
- src/**/*.ts
- utils/**/*.js
```

**Dead Code Detection:**

```
Description: "Remove unused imports, variables, and functions. Keep codebase clean and maintainable by eliminating dead code."

File Patterns:
- **/*.js
- **/*.ts
- **/*.jsx
- **/*.tsx
```

### API and Architecture Rules

**REST API Conventions:**

```
Description: "REST API endpoints must use kebab-case and follow RESTful patterns: GET /users, POST /users, PUT /users/:id, DELETE /users/:id."

File Patterns:
- routes/**/*.js
- src/api/**/*.ts
- controllers/**/*.py
```

## Pattern Examples

### Common File Patterns

| Pattern                      | Description                      |
| ---------------------------- | -------------------------------- |
| `src/**/*.{js,ts}`           | All JavaScript/TypeScript in src |
| `**/*.test.*`                | All test files                   |
| `src/components/**/*.tsx`    | React components only            |
| `!**/node_modules/**`        | Exclude dependencies             |
| `{api,routes}/**/*.js`       | API and route files              |
| `src/{models,entities}/**/*` | Data models                      |
| `**/*.{css,scss,less}`       | Stylesheets                      |
| `src/utils/**/*.ts`          | Utility functions                |

### Advanced Patterns

| Pattern                                 | Description                 |                              |
| --------------------------------------- | --------------------------- | ---------------------------- |
| \`src/\*\*/!(\*.test                    | *.spec).*\`                 | Source files excluding tests |
| `**/*.{config,conf}.{js,ts}`            | Configuration files         |                              |
| `{src,lib,app}/**/*.ts`                 | Multiple source directories |                              |
| `**/*{Controller,Service,Repository}.*` | Specific class types        |                              |
| `src/**/*.{gql,graphql}`                | GraphQL files               |                              |

Custom rules work alongside CodeAnt's built-in detection, providing comprehensive code review coverage tailored to your team's specific needs.
