langgraph 0.2.33

Summary of Changes

• Added InjectedStore annotation for injecting LangGraph store objects into tool arguments (#1968)
• Enhanced ToolNode to support automatic store injection for tools with InjectedStore annotations (#1968)
• Improved RunnableCallable to better handle keyword arguments, allowing them to override config values (#1968)

Detailed Changes

langgraph.prebuilt.tool_node.InjectedStore

• Added new InjectedStore class that allows injecting the LangGraph store into tool arguments (#1968)
• Similar to InjectedState, this annotation hides parameters from the tool-calling model
• Allows tools to access and manipulate store data directly

langgraph.prebuilt.tool_node.ToolNode

• Added support for automatic store injection when tools have arguments annotated with InjectedStore (#1968)
• Optimized tool argument processing by precomputing and caching state and store arguments
• Refactored _inject_state method and added new methods _inject_store and _inject_tool_args
• Added store parameter to _func and _afunc methods
• Enhanced invoke and ainvoke methods to handle the store parameter

langgraph.utils.runnable.RunnableCallable

• Improved handling of keyword arguments in invoke and ainvoke methods (#1968)
• Keyword arguments can now override config values instead of being ignored
• Added check to use provided keyword args before falling back to config values
• Fixed error logic to consider both config and direct kwargs for required parameters
