subtopic

Tools, knowledge and memory in a call

10 min applied15 min research3 curated resources

Learn the three things that make the agent useful: tools/function calling (check a slot, book an appointment, look up an order — the agent says a short filler while the tool runs); knowledge (RAG over FAQs and policies so answers are correct); memory and state (what has been collected so far: name, date, reason; and caller history from the CRM).

Builds on: 3.4 Tool calling, 4.3 Prepare the documents, 4.4 Generate the answer, 2.5 Memory
