# @-Mention Validation

Validate that all @-mentions in codebase resolve to existing files.

## Usage

```bash
/mention-validate                    # Validate current directory
/mention-validate --strict           # Fail on any broken mention
/mention-validate --output report.md # Write report to file
```

## Options

| Option | Default | Description |
|--------|---------|-------------|
| --target | . | Directory to validate |
| --strict | false | Exit with error on broken mentions |
| --output | stdout | Write report to file |

## Process

1. **Scan** all files for @-mention patterns
2. **Extract** @-mention paths
3. **Resolve** paths relative to repo root
4. **Report** broken/valid mentions

## Output Format
