# Build with Composer

> Create or modify an agent through the AI-assisted workspace.

Composer turns a written goal into an agent configuration. Use it to build a new AI voice agent, modify an existing agent, or explore a workflow before opening the full builder.

## Start a build

<Steps>
  <Step title="Describe the outcome">
    State the caller, call direction, goal, information the agent needs, actions it may take, and when it should transfer or end the call.
  </Step>

  <Step title="Add context">
    Attach an existing agent, knowledge base, or document when Composer should use that resource. You can also mention an agent or knowledge base in the message.
  </Step>

  <Step title="Review the proposal">
    Confirm important choices such as structure, voice, and capabilities. Treat generated configuration as a draft that still needs review.
  </Step>

  <Step title="Test and publish">
    Talk to the generated agent, inspect it in the builder, correct any unsupported assumption, and publish only after simulated calls pass.
  </Step>
</Steps>

Composer keeps chat history so you can return to earlier work. Do not paste credentials or production customer data into a Composer message or attachment.
