Problem outcome: unknown
Enables an agent to resume a partial papermill run after a crash: checkpoint outputs per cell and restart from the failure point. For agent builders.
Gives an agent the ability to interrupt a runaway cell: expose kernel interrupt, detect runaway execution, and define the interrupt-then-decide policy. For agent builders.

Covers agent context overflow on large catalog uploads: chunk into safe batches with checkpoints. Use it when whole-catalog prompts get rejected. Not for output truncation.
Migrates a deprecated LangGraph MessageGraph to StateGraph with a messages key. Use when you see the MessageGraph deprecation warning, when upgrading LangGraph, and when you want the same message-list behavior on the supported API. Not for custom state schemas or brand-new graphs (build those on StateGraph directly).
Fixes the LangGraph error raised when interrupt() is used on a graph compiled without a checkpointer. Use when adding human-in-the-loop pauses to a graph that was compiled bare, or when the error appears after refactoring compile args. Not for resume-from-interrupt bugs, which need the same thread_id instead.
Fixes LangGraph checkpoint restore failing on thread_id mismatch. Use when get_state or restore returns nothing for a known thread, when an agent passes the wrong thread_id, or when checkpoint namespaces changed. Not for corrupt checkpoints, for invalid updates, or for missing checkpointer config.
Fixes LangGraph routing failures where Send() or a conditional edge targets a node the graph cannot find. Covers listing registered node names, fixing typos in Send targets, adding missing nodes, and aligning the conditional edge path map. Use when a router names a node that does not resolve.
Fixes LangGraph GraphRecursionError when a graph exceeds the default 25-step recursion limit. Use when nodes loop without terminating, when you need to tell a real loop from a legitimately long graph, and when raising the limit safely. Not for exceptions inside a single node or for state-schema validation errors.
Fixes LangGraph's InvalidUpdateError on the messages key, which fires when one graph step writes two values to a channel with no reducer. Covers adding the add_messages reducer to the state schema, merging parallel node updates, and fixing Send-based fan-outs that double-write. Use when the error names a key and refus…
Fixes LangGraph checkpointer.get_tuple returning None when the config is missing configurable.thread_id. Use when checkpoint reads come back empty after a working invoke, when the thread id was passed as a bare string instead of a config dict, or when post-interrupt resumes find no state. Not for store connection erro…
