# Feature setup guides

> Find the setup, verification, and limits for every customer-facing Athena feature.

Start with [Your first agent](/guides/first-agent.md), then use this checklist to add the capabilities your agent needs. Each guide explains the required configuration, how to check the result, and any call-path or provider restrictions. Features shown as unavailable in your account cannot be enabled by adding a prompt.

## Verify a configuration

Save the relevant settings, validate the workflow, test with synthetic inputs and destinations you control, and inspect the resulting run. Publish the draft when the change is ready for published triggers. A saved setting, an accepted API request, and a successful conversation are separate checks.

The [coverage notes](/guides/coverage.md) distinguish live checks, local contract checks, and unavailable integrations. This setup map does not imply every provider combination has been tested. Disabled **Integration (Coming Soon)** choices are not released integrations. Administration-only operations are outside the customer setup guides.
