# Agents

> Build an agent in the Builder, then test it, protect it and publish it.

## Build

* [The agent Builder](/guides/agents/builder): what Ryvo Engine is, how an agent is assembled in the Builder, how it is tested, how it is published and which channels it serves today.
* [Create a new agent](/guides/second-agent): add another agent to your account: request it and fill in its form in minutes.
* [Voice, hearing and model](/guides/agents/voice-hearing-and-model): the three selectors in the Builder header: the LLM that thinks, the STT that listens and the TTS that speaks.
* [Knowledge base](/guides/agents/knowledge-base): upload documents or web pages so the agent answers with the information of your business.
* [Tools: connect your agent to your systems](/guides/agents/tools): how to register a tool (custom function) in the Builder, what HTTP request your server receives and what it has to answer.

## Test and publish

* [Test your agent](/guides/agents/test-your-agent): talk to the draft by chat or by voice from your browser before publishing it, and read the trace of every turn.
* [Agent protection](/guides/agents/agent-protection): the rules Ryvo puts ahead of your instructions so the agent stays on topic and cannot be manipulated.
* [Put your agent on your website](/guides/agents/web-widget): add a chat and voice bubble to your site with one script tag.
