### Command Override Implementation

The cog uses a clean override mechanism:
```python
async def _disable_core_commands(self):
    """Disable Red's built-in contact and dm commands."""
    core_cog = self.bot.get_cog("Core")
    commands_to_disable = ["contact", "dm"]
    for cmd_name in commands_to_disable:
        cmd = self.bot.get_command(cmd_name)
        if cmd and cmd.cog_name == "Core":
            cmd.enabled = False
```

### Known Limitations

- Users must be in the server to use contact (by design)
- DMs must be enabled for user to receive replies
- Maximum 25 categories (Discord dropdown limit)
- Thread cleanup runs every 5 minutes (configurable in code)

### Future Considerations

Potential features for future versions:
- Rate limiting
- Priority queues
- Auto-responses
- Ticket numbers
- Transcript generation
- Staff assignments
- Analytics
