# Channel behaviours

> Autothreads, gallery channels, command-only channels and news publishing.

Four small features that change how a specific channel behaves.

## Autothreads

Create a thread on every message in a channel. Turns a feed-style channel into something you can actually discuss.

```javascript theme={null}
!autothread add #showcase
```

Requires **Manage Threads**. Aliases: `autothreads`, `threadify`, `athread`.

<AccordionGroup>
  <Accordion title="Naming threads" icon="tag">
    ```javascript theme={null}
    !autothread name #showcase {user.name}'s post
    ```

    Supports [variables](/scripting/variables). `!autothread variables` lists what's available. You can also pass a name when adding:

    ```javascript theme={null}
    !autothread add #showcase {user.name}'s post
    ```
  </Accordion>

  <Accordion title="A message inside each thread" icon="message">
    ```javascript theme={null}
    !autothread message #showcase {description: Nice one — discuss it here.}
    ```

    Sent automatically in every created thread. Remove with `!autothread message remove #showcase`.
  </Accordion>

  <Accordion title="Auto-reactions" icon="face-smile">
    ```javascript theme={null}
    !autothread reactions add #showcase 🔥
    !autothread reactions add #showcase 💯
    !autothread reactions remove #showcase 🔥
    !autothread reactions clear #showcase
    ```

    Reacts to the original message, not the thread. Saves everyone the ritual first reaction.
  </Accordion>

  <Accordion title="Archive time and slowmode" icon="clock">
    ```javascript theme={null}
    !autothread archive #showcase 1440
    !autothread slowmode #showcase 10
    ```

    Archive duration is in **minutes** — 60, 1440 (a day), 4320 (three days) or 10080 (a week). Slowmode is in seconds.
  </Accordion>
</AccordionGroup>

```javascript theme={null}
!autothread list
!autothread remove #showcase
!autothread clear
```

<Note>
  To stop a specific thread being auto-archived by Discord, that's `!thread add` — see [Channels & threads](/moderation/channels#preventing-auto-archive).
</Note>

## Gallery channels

Only allow messages with attachments. Anything without one gets deleted.

```javascript theme={null}
!gallery add #art
!gallery list
!gallery remove #art
!gallery clear
```

Requires **Manage Messages**. Alias: `imgonly`.

<Tip>
  A gallery channel plus autothreads is the standard art-channel setup: images only in the channel, all discussion in threads.

  ```javascript theme={null}
  !gallery add #art
  !autothread add #art {user.name}'s art
  !autothread reactions add #art ❤️
  ```
</Tip>

## Command-only channels

The opposite of a gallery: only allow **commands**. Everything else is deleted.

```javascript theme={null}
!commandonly add #bot-commands
```

Requires **Manage Messages**. Aliases: `cmdonly`, `commandsonly`.

By default mira recognises the prefixes other bots commonly use and leaves those messages alone. To tighten or loosen that:

<CodeGroup>
  ```javascript Only mira's commands theme={null}
  !commandonly mira #bot-commands on
  ```

  ```javascript Only slash commands theme={null}
  !commandonly slash #bot-commands on
  ```

  ```javascript Allow an unusual prefix theme={null}
  !commandonly prefix add #bot-commands $$
  ```

  ```javascript Allow every common prefix again theme={null}
  !commandonly prefix clear #bot-commands
  ```
</CodeGroup>

```javascript theme={null}
!commandonly list
!commandonly remove #bot-commands
!commandonly clear
```

## Auto-publishing

Automatically publish messages posted in announcement channels, so they reach every server that follows yours.

```javascript theme={null}
!publisher add #announcements
!publisher list
!publisher remove #announcements
!publisher clear
```

Requires **Manage Messages**. Alias: `announcement`.

<Warning>
  Discord limits announcement channels to **10 published messages per hour**. Past that, publishing silently fails until the window resets — so don't point this at a busy channel.
</Warning>
