### Before and After Examples

#### Before Transformation:
```javascript
/**
 * Get user data from database
 */
async function getUserData(userId) {
    return await db.users.findById(userId);
}
```

#### After Transformation:
```javascript
// Get user data from database
// @function getUserData - Async function for database operations
// @param {string} userId - User identifier for database query
// @returns {Promise<Object>} User data object from database
async function getUserData(userId) {
    return await db.users.findById(userId);
}
```

## Safety Guidelines

### Step-by-Step Safe Usage

| Step | Action |
|------|--------|
| 1 | Always preview first |
| 2 | Use backup for important files |
| 3 | Test results before committing |

```bash
# Step 1: Preview changes safely
npx @chahuadev/fix-comments@beta . --dry-run

# Step 2: Apply changes with backup
npx @chahuadev/fix-comments@beta . --add-missing --backup

# Step 3: Test your code after changes
npm test  # or your testing command
```

### Critical Safety Practices
```bash
# ALWAYS use backup flag for important files
fix-comments ./src --backup --dry-run

# Test in isolated environment first
cp -r ./my-project ./test-project
cd test-project
fix-comments . --backup
```

### Known Beta Issues (v3.0.1-beta)

**Parser Context Improvements Needed**
- Complex TypeScript interface chains may need manual review
- Arrow functions with complex destructuring might generate contextual warnings
- JSX components with conditional rendering require additional validation

**Pattern Recognition Limitations**
- Generic type constraints with multiple inheritance need manual verification
- Conditional types (A extends B ? C : D) may not be fully optimized
- Template literal types might require additional processing

**Bug Reporting Guidelines**
```bash
# Generate detailed report for issues
fix-comments --dry-run --verbose > issue-report.txt

# Include in GitHub issue:
# - Code sample (minimal reproduction case)
# - Expected vs actual behavior
# - System info (OS, Node.js version)
# - Generated report file
```
