Prompt: Creating the Personality and Behavior of Your Agent

The Prompt defines how your Agent communicates — its tone, responses, and behavior during interactions.
Prompts can also include metadata from your context using variables such as {variable_name}.

Creating a Prompt

You can write a Prompt from scratch or enhance it with reusable Blocks. Prompt Example

Using Blocks in Prompts

Fluents.ai supports a modular Block system, allowing you to build Prompts with reusable components. A Block is a predefined set of instructions, context, or logic that can be inserted into a Prompt.
Multiple Blocks can be combined in a single Prompt to simplify complex workflows.

Examples of Blocks

  • Knowledge Base Block — Load company-specific facts or FAQs.
  • Voicemail Detection Block — Add logic for handling voicemail scenarios.
  • Fallback Block — Define responses for uncertainty or no reply.
  • Compliance Block — Insert disclaimers or consent language as required.
By combining Blocks, you can create flexible and consistent Agent behavior across multiple Prompts. Block Example

Adding a Block

  1. In the interface, select the Block you want to add.
  2. Choose whether you’re creating a full Prompt or a standalone Block.
  3. If creating a Block, assign it a tag to categorize and reuse it effectively.
