+"""This module provides dynamic access to deprecated JSON tools in LangChain.

+It ensures backward compatibility by forwarding references such as
+`JsonGetValueTool`, `JsonListKeysTool`, and `JsonSpec` to their updated
+locations within the `langchain_community.tools` namespace.
+
+This setup allows legacy code to continue working while guiding developers
+toward using the updated module paths.
