Enable
1
Open Tools
Open the workflow, select an Agent, Supervisor, or Task, then open Tools.
2
Turn it on
Under Knowledge, enable Search knowledge base.
3
Choose retrieval
In Configure Search knowledge base, pick:
- Agent calls when needed — the agent decides when to search.
- Auto-retrieve each turn — relevant knowledge is added before every reply. The agent does not call the tool.
The tool is on. Ask something only your sources cover, and confirm the reply uses that content.
In the conversation
The agent answers from your sources instead of guessing. Auto-retrieve keeps search off the tool list but still injects context each turn.Empty or stale sources produce weak answers. Update the knowledge base, then test again.
