# Progress messages while a Playbook tool runs

A new **Send progress messages during long tool runs** setting lets the AI Agent keep the end user informed while a Playbook `RUN` step waits on a slow API tool or Code tool. With the setting on, the Agent sends a short message after the tool has run for 10 seconds. It sends another at 20 seconds. Then it sends one every 20 seconds until the result arrives. Each message says the Agent is still working, in the language of the conversation. A tool that returns within 10 seconds sends nothing.

The setting is off by default. Turn it on under **Config > AI AGENT > Settings** on the **Preferences** tab, next to **Send acknowledgement messages**, or through the `enable_progress_messages` field of the Persona API. It applies to Messaging conversations only.
