## 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')
}
```

## Common Workflows

These workflows were detected from analyzing commit patterns.

### Database Migration

```

### Add Language Rules

Adds a new programming language to the rules system, including coding style, hooks, patterns, security, and testing guidelines.

**Frequency**: ~2 times per month

**Steps**:
1. Create a new directory under rules/{language}/

## 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
