# Cleanup Channel

A Mattermost plugin that lets system administrators remove all messages from a channel.

## Features

- **Channel menu action**: "Remove all messages" appears in the channel header menu for system administrators only.
- **Slash command**: `/cleanup-channel` removes all messages from the current channel (system administrators only).
- **Defense in depth**: Both the web app and server verify that the user is a system administrator before performing any cleanup.

## Build

```bash
make dist
```

The plugin bundle is written to `dist/com.fmartingr.mattermost-plugin-cleanup-channel-*.tar.gz`.

## Usage

1. Upload and enable the plugin in **System Console → Plugins → Plugin Management**.
2. As a system administrator, open a channel and use the channel header menu (**⋯**) → **Remove all messages**.
3. Or run `/cleanup-channel` in the channel you want to clean up.

Both actions ask for confirmation before deleting messages.

## Development

```bash
make deploy
```

Requires a local Mattermost server configured for plugin development. See the [Mattermost plugin developer guide](https://developers.mattermost.com/integrate/plugins/).
