About this skill

This skill serves as a comprehensive guide for the Claude AI agent, detailing the specific development conventions and patterns established within the `everything-claude-code` JavaScript project. It covers essential aspects such as the primary use of JavaScript, adherence to a hybrid module organization for code structure, separate test file locations, and the mandatory use of conventional commits for clear and consistent commit history. By utilizing this skill, Claude can generate, modify, and review code, write tests, and create commit messages that strictly conform to the project's established best practices, ensuring high code quality, maintainability, and seamless integration into the existing codebase.

Best use case

Ensures AI-generated code, tests, and commit messages for the `everything-claude-code` project strictly adhere to its specific JavaScript development conventions, architectural patterns, and conventional commit standards, promoting consistency and maintainability.

Development conventions and patterns for everything-claude-code. JavaScript project with conventional commits.

The Claude AI agent will produce code, tests, and commit messages for the `everything-claude-code` project that are perfectly aligned with its defined JavaScript development conventions, hybrid module organization, separate test locations, and conventional commit standards, leading to consistent, high-quality, and easily maintainable contributions.

Practical example

Example input

Using the `everything-claude-code-conventions` skill, add a new utility function `formatDate` to `src/utils/dateHelpers.js`. This function should take a Date object and return a 'YYYY-MM-DD' string. Ensure it follows the hybrid module organization. Also, generate a conventional commit message for this change.

Example output

```javascript
// src/utils/dateHelpers.js

// Existing code...

/**
 * Formats a Date object into a 'YYYY-MM-DD' string.
 * @param {Date} dateObj The date object to format.
 * @returns {string} The formatted date string.
 */
export function formatDate(dateObj) {
  const year = dateObj.getFullYear();
  const month = String(dateObj.getMonth() + 1).padStart(2, '0');
  const day = String(dateObj.getDate()).padStart(2, '0');
  return `${year}-${month}-${day}`;
}

// Note: If the file uses 'module.exports' for other exports, 
// the AI would adapt to respect the 'hybrid module organization'.
```

```
feat(utils): Add formatDate utility function

Adds a new `formatDate` utility function to `src/utils/dateHelpers.js`
for consistent date string formatting (YYYY-MM-DD). This function
adheres to the project's hybrid module organization and JavaScript
coding conventions.
```

When to use this skill

  • When making any changes or contributions to the `everything-claude-code` repository.
  • When adding new features or modules that need to follow established project patterns and architectural guidelines.
  • When writing or modifying tests to ensure they match the project's specific conventions for test location and structure.
  • When generating commit messages for changes within the `everything-claude-code` project, requiring conventional commit format.

When not to use this skill

  • When working on a different project that has its own distinct development conventions or tech stack.
  • When the task does not involve code generation, modification, testing, or commit message creation within the `everything-claude-code` repository context.
  • When the goal is to produce generic code without specific project style or architectural constraints.

## Architecture

### Project Structure: Single Package

This project uses **hybrid** module organization.

### Configuration Files

- `.github/workflows/ci.yml`
- `.github/workflows/maintenance.yml`
- `.github/workflows/monthly-metrics.yml`
- `.github/workflows/release.yml`
- `.github/workflows/reusable-release.yml`
- `.github/workflows/reusable-test.yml`
- `.github/workflows/reusable-validate.yml`
- `.opencode/package.json`
- `.opencode/tsconfig.json`
- `.prettierrc`
- `eslint.config.js`
- `package.json`

### Guidelines

- This project uses a hybrid organization
- Follow existing patterns when adding new code

## Code Style

### Language: JavaScript

### Naming Conventions

| Element | Convention |
|---------|------------|
| Files | camelCase |
| Functions | camelCase |
| Classes | PascalCase |
| Constants | SCREAMING_SNAKE_CASE |

### Import Style: Relative Imports

### Export Style: Mixed Style


*Preferred import style*

```typescript
// Use relative imports
import { Button } from '../components/Button'
import { useAuth } from './hooks/useAuth'
```

## Testing

### Test Framework

No specific test framework detected — use the repository's existing test patterns.

### File Pattern: `*.test.js`

### Test Types

- **Unit tests**: Test individual functions and components in isolation
- **Integration tests**: Test interactions between multiple components/services

### Coverage

This project has coverage reporting configured. Aim for 80%+ coverage.


## Error Handling

### Error Handling Style: Try-Catch Blocks


*Standard error handling pattern*

```typescript
try {
  const result = await riskyOperation()
  return result
} catch (error) {
  console.error('Operation failed:', error)
  throw new Error('User-friendly message')
}
```

## Best Practices

Based on analysis of the codebase, follow these practices:

### Do

- Use conventional commit format (feat:, fix:, etc.)
- Follow *.test.js naming pattern
- Use camelCase for file names
- Prefer mixed exports

### Don't

- Don't write vague commit messages
- Don't skip tests for new features
- Don't deviate from established patterns without discussion
