What it is
Agent Builder is the primary interface for creating Agentforce agents in Salesforce Setup. You define what your agent can discuss (topics), what it can do (actions), and what it cannot do (guardrails). Actions can invoke Apex, Flows, Prompt Templates, or external APIs.
Why it matters
Agent Builder democratizes AI agent creation. Admins can build production agents using clicks, not code. This means faster deployment and lower cost — you do not need a dedicated AI engineering team to put agents into production.

How it connects
Agent Builder is where you configure agents that run on the Atlas Reasoning Engine. It connects to Prompt Builder for custom prompts, Flow Builder for automation, and Data Cloud for grounding.
Good to know
Start with one topic and 2-3 actions. Test thoroughly before adding complexity. Agents with too many topics often perform worse than focused single-purpose agents.
