The Agent Handbook is a collection of ready-to-use prompt presets that improve how your agent communicates. Each preset encodes a specific best practice — toggle it on and the behavior is added automatically, no prompt writing needed.
New agents are created with Default Personality and AI Disclosure When Asked enabled by default.
How It Works
The Agent Handbook organizes presets into three categories:
- Personality & Tone — Shape how the agent sounds and feels in conversation
- Accuracy & Format — Improve how the agent handles names, numbers, and data (voice agents only)
- Trust & Safety — Control transparency and scope of responses
Toggle any preset on or off from the Agent Handbook panel. Each preset adds a small number of tokens to every interaction — estimated token counts are shown on hover.
To open the Agent Handbook, click the Agent Handbook button in the prompt section of your agent settings.

FAQ
Can I customize the content of a preset?
Handbook presets are fixed best-practice templates. To customize behavior further, add your own instructions directly in the prompt — handbook presets and custom prompts work together without conflict.
Do handbook presets conflict with my custom prompt?
No. Presets are appended to your prompt without overriding any of your custom instructions.
Why are some presets greyed out for my chat agent?
Accuracy & Format presets are voice-only features. They are automatically disabled for chat agents and cannot be toggled on.
