# Capabilities

> Real-time hooks available with the LiveKit integration

## What's possible

* **Start from any reference image** at call creation time.
* **Change avatar appearance** during an active call by updating the reference image.
* **Change speaking behavior** during an active call by updating the speaking prompt (`agent_prompt`).
* **Change idle behavior** during an active call by updating the idle prompt (`agent_idle_prompt`).

## Common use cases

* **In-call visual changes:** swap the reference image mid-session to change scene or character context.
* **Prompt-driven behavior updates:** adjust speaking/idle prompts in real time to shift demeanor by context.
* **State-aware behavior:** use one demeanor while speaking and another while idle.
* **Programmatic orchestration:** trigger visual and behavioral updates from your app logic in real time.
