Steps to reproduce

use following params to config a tool:

  - name: test_number
    type: number
    required: false
    label:
      en_US: Test Number
    min: 5
    placeholder:
      en_US: Please input a number between 5 and 10
      zh_Hans: 请输入一个介于 5 和 10 之间的数字
    form: llm
  - name: type
    type: select
    required: false
    label:
      en_US: search type
    form: llm
    placeholder:
      en_US: Please choose an option
    options:
      - value: sports
        label:
          en_US: sports
      - value: games
        label:
          en_US: games

simply because the form type is llm, it is all display as text.

@dosubot[bot] commented on GitHub (Jul 22, 2024):

The tool parameters are not displaying correctly because parameters with the form type llm are meant to be inferred by the Agent and not displayed on the frontend. This is why they are not appearing as expected in your form.

For parameters to be displayed and filled in by the user on the frontend, you should use the form type form instead of llm. The llm form type is specifically designed for parameters that the Agent infers, and these parameters are not intended to be displayed or filled in by the user on the frontend [1][2][3][4].

Here is an example of how you can modify your configuration:

- name: test_number
  type: number
  required: false
  label:
    en_US: Test Number
  min: 5
  placeholder:
    en_US: Please input a number between 5 and 10
    zh_Hans: 请输入一个介于 5 和 10 之间的数字
  form: form  # Change from 'llm' to 'form'
- name: type
  type: select
  required: false
  label:
    en_US: search type
  form: form  # Change from 'llm' to 'form'
  placeholder:
    en_US: Please choose an option
  options:
    - value: sports
      label:
        en_US: sports
    - value: games
      label:
        en_US: games

This should ensure that the parameters are displayed correctly on the frontend.
