Elasticsearch：如何在 workflow 里调用一个 agent

在 AI Agent Builder 里，我们可以创建一个 workflow 的工具从而达到调用 workflow 的目的。我们是不是也可以在 workflow 里调用 AI Agent Builder 里所创建的 Agent 呢？答案是肯定的。下面我们来用一个简单的例子来进行展示。

创建一个 agent

我们创建的一个 agent 的名字叫做 generate_audio_product_json。它是用来解析我们的输入，并提区我们所需要的信息。它的创建非常融，我们甚至不需要使用任何的工具。

Custom Instructions：

创建一个 workflow 并调用 agent

我们在 workflow 里创建一个如下的 workflow：

yaml 复制代码

`

1.  version: "1"
2.  name: invoke_audio_product_agent
3.  description: Extract structured product data using an AI agent
4.  enabled: true

6.  triggers:
7.    - type: manual

9.  inputs:
10.    - name: product_info
11.      type: string
12.      required: true
13.      description: product descriptions

15.  steps:
16.    # Step 1: Log input (optional but recommended)
17.    - name: log_input
18.      type: console
19.      with:
20.        message: "Incoming product info: {{ inputs.product_info }}"

22.    # Step 2: Invoke your agent
23.    - name: generate_product_json
24.      type: ai.agent
25.      with:
26.        agent_id: "generate_audio_product_json"
27.        message: |
28.          Extract structured product data from the following input.

30.          Input:
31.          {{ inputs.product_info }}

33.          Return ONLY valid JSON.

35.    # Step 3: Print the result
36.    - name: print_result
37.      type: console
38.      with:
39.        message: "{{ steps.generate_product_json.output }}"
