# Slack Agent

> Answer support questions in Slack, and control when the bot engages and what it says when it can't help.

In Slack, Decimal answers support questions in direct messages to the bot and in channels where someone has invited it. This needs the [Slack integration](/integrations/slack) connected first.

Open **Agents**, select **Slack**, then set its [tone and voice](/agents/tone-voice) or the settings below.

* **Reply to direct messages** controls whether a DM to the bot gets a real answer. Turn it off and DMs get your default response instead.
* **Monitor tagged threads** keeps the bot in a conversation once someone has mentioned it. On, it answers follow-ups in that thread without being mentioned again. Off, every question needs its own mention.

## Default Response

When the bot isn't answering somewhere, this is what it says instead. Write it as a message to the person who asked, and use variables like `{{user.first_name}}` to address them by name.

You can also name a fallback channel by its Slack channel ID, to point people at the place your team does want the question asked.
