Description

Hello, everyone. I think I have encountered some problems while looking up the official documentation of langchain recently. I found that many apis are not clearly stated in the official documentation, such as the following

from langchain_core.prompts import (
ChatPromptTemplate,
HumanMessagePromptTemplate,
SystemMessagePromptTemplate,

" HumanMessagePromptTemplate, SystemMessagePromptTemplate in the document I failed to find the two apis related documentation, I through the search box and Ask the AI function to query their related documents, and failed to find it. I only found out that they were from langchain_core.prompts after checking the source code. But I checked the link:
https://reference.langchain.com/python/langchain_core/prompts/#langchain_core.prompts.chat.ChatPromptTemplate
No explanations for their usage were found. I hope my friends can help me check if I have missed any documents or where I can find their usage and purpose. Thank you all in advance again, big shots.

@eyurtsev commented on GitHub (Nov 24, 2025):

Many APIs are not documented in the official docs b/c most users don't need to know about them. For example, the templates are mostly used from within ChatPromptTemplate, and users don't need to directly use the chat message template messages
