# Autoreactions plugin

Automatically react to new messages with a specific emoji. Rules can apply to one channel or all channels, with flexible triggers and optional cadence controls.

## Configuration

```yaml
plugins:
  autoreactions:
    enabled: true
    config:
      rules:
        - id: 1
          channel_id: "*"
          emoji: "👍"

        - id: 2
          channel_id: "123456789012345678"

### Add form

1. Run `/autoreaction add emoji:…` (unicode or custom emoji)
2. A Discord modal opens (see [modal components](https://docs.discord.com/developers/components/using-modal-components)) with:
   * **When should it react?** — dropdown (every message, contains, starts with, exact, regex)
   * **Match text** — optional; required unless you chose every message
   * **Channel** — optional channel picker (empty = all channels)
   * **Extras** — multi-select for cadence/filters (every Nth match, cooldowns, attachments/links only)

## Requirements

* The bot needs **Add Reactions** in the target channel(s).
* Bot messages are not auto-reacted.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://dreamliner.gitbook.io/dreamliner-docs/docs/plugins/autoreactions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
