Acting / Tool Invocation

### Giai đoạn: Nền Tảng & Khái Niệm Cốt Lõi **Acting / Tool Invocation** Acting, also called tool invocation, is the step where the AI chooses a tool and runs it to get real-world data or to change something. The agent looks at its current goal and the plan it just made. It then picks the best tool, such as a web search, a database query, or a calculator. The agent fills in the needed inputs and sends the call. The external system does the heavy work and returns a result. Acting ends when the agent stores that result so it can think about the next move. ### Khái niệm cốt lõi: 1. **The agent looks at its current goal and the plan it just made** 2. **It then picks the best tool, such as a web search, a database query, or a calculator** 3. **The agent fills in the needed inputs and sends the call** ### Tài liệu tham khảo chính thống: - [What are Tools in AI Agents?](https://huggingface.co/learn/agents-course/en/unit1/tools) (article) - [What is Tool Calling in Agents?](https://www.useparagon.com/blog/ai-building-blocks-what-is-tool-calling-a-guide-for-pms) (article)
