Report #53359

[architecture] Starting a new session and losing the exact conversational state or task progress

Serialize the agent's state \(tool call stack, current plan, and recent context window\) into a persistent checkpoint. On resumption, reconstruct the context window with a summary of the previous session plus the serialized state, rather than just injecting raw past messages.

Journey Context:
Dumping raw chat history from a past session into a new context window eats up tokens and breaks the causal chain of the new session. Summarization plus state reconstruction allows the agent to pick up where it left off without the token overhead of full transcripts, preserving the exact execution graph and variables needed to continue the task.
