To use PromptTemplate to pass input as variables with ReActAgent, you need to follow these steps:

Import the PromptTemplate from llama_index.core.

Plain Text

from llama_index.core import PromptTemplate

Define your prompt string. This string can contain placeholders for variables that you want to pass in later.

Plain Text

react_system_header_str = """\
You are designed to help with a variety of tasks, from answering questions   
to providing summaries to other types of analyses.

Create a PromptTemplate object using the string you defined.

Plain Text

react_system_prompt = PromptTemplate(react_system_header_str)

Use the get_prompts() method of the ReActAgent to get the current prompts.

Plain Text

agent.get_prompts()

Update the prompts using the update_prompts() method of the ReActAgent. Pass in a dictionary where the key is the name of the prompt you want to update and the value is the PromptTemplate object you created.

Plain Text

agent.update_prompts({"agent_worker:system_prompt": react_system_prompt})

Here is the complete code:

Plain Text

from llama_index.core import PromptTemplate

react_system_header_str = """\
You are designed to help with a variety of tasks, from answering questions   
to providing summaries to other types of analyses.

react_system_prompt = PromptTemplate(react_system_header_str)

agent.get_prompts()

agent.update_prompts({"agent_worker:system_prompt": react_system_prompt})

Please note that the placeholders in your prompt string should match the keys in the dictionary you pass to update_prompts().
