Original Pull Request: https://github.com/langchain-ai/langgraph/pull/6375

State: closed
Merged: Yes

REMOVE_ALL_MESSAGES is a public constant used with RemoveMessage to clear all messages from the state:

from langchain_core.messages import RemoveMessage
from langgraph.graph.message import REMOVE_ALL_MESSAGES

# Clear all messages
[RemoveMessage(id=REMOVE_ALL_MESSAGES)]

However, it is not exported in all, causing:

Linting errors in IDEs (PyCharm)
no-member warnings from Pylint
Confusion for users

This PR:

Adds REMOVE_ALL_MESSAGES to all
Adds inline docstring with usage example

No runtime behavior changes — only improves IDE support and API clarity.
