Tool use equips an agent to delegate specialized tasks to external tools, libraries, or APIs, then integrate their results into broader decision-making. This keeps the agent modular instead of forcing it to recreate every capability internally. section 9.1.2
A tool-using agent can:
- Retrieve real-time stock data through a price API. section 9.1.2
- Invoke sentiment analysis to interpret market news. section 9.1.2
- Identify an appropriate tool, orchestrate calls, and combine the returned results. section 9.1.2
