Topic names and classification descriptions for routing
Key Takeaway
Writing clear, distinct names and classification descriptions is the main way an admin controls which subagent an agent picks.
An Agentforce agent splits its work into jobs called subagents. When a user sends a message, the agent must route it to the right subagent. It decides mainly by comparing the conversation to each subagent's name and classification description.
What a subagent is
A subagent is one job an agent can do, such as Order Management or Password Reset. Together, the subagents assigned to an agent define everything the agent can handle. Each subagent contains instructions, which guide how the agent reasons, and actions, which are the tools the agent can use.
Beginning in April 2026, agent topics are called subagents, so you may see both terms. The name changed, but how they work did not.
