Builders introduction

Builders are the AI agents you create on Brixel. Each Builder lives inside a chat interface and can use Tasks and Knowledges to solve real workflows end to end.

What a Builder is made of​

A Builder combines:

  • Tasks: the tools it can execute (Actions, Tools, Variants, Plan Generators, Artifacts).
  • Knowledges: the context it can read (Abilities, Documents, Memories).
  • Rules and behavior: how it should respond, reason, and operate.

How Builders are used​

A Builder lives inside a conversation. You can attach files to individual messages, and those files become available as inputs for tasks and tools.

This makes the Builder a practical workspace: chat, context, and execution all happen in one place.

tip

In edit mode, you can test your Builder without saving its configuration—perfect for validating behavior before deploying.
