# Custom Agents FAQ

#### Do agents always use AI?

No. Some agents use AI heavily for summarization, drafting, or analysis. Others focus on routing, notification, transformation, or delivery.

#### Can agents send Slack messages or emails?

Yes. Custom agents can produce email outputs and use messaging actions available in the picker.

#### Can agents create slides or files?

Yes. Outputs include slides and file.

#### Can agents respond to outside systems?

Yes. Custom agents support webhook triggers.

#### How do I test an agent before publishing?

Use "New test run", pass realistic trigger data, and inspect the results before you publish.

#### What is the best first agent to build?

Start with something repeatable and high-value, like meeting prep, post-meeting follow-up, a weekly summary, or a webhook-triggered notification.
