Report #69290

[architecture] Agent loses track of ongoing tasks or tool execution states when the context window shifts or is truncated

Externalize the agent's scratchpad and execution state into a structured database or state machine, and only inject the current relevant state slice into the prompt.

Journey Context:
Developers often treat the LLM context window as the sole source of truth for the agent's current state, plan, and tool outputs. In long-running agentic loops, context limits force truncation, which destroys the agent's working memory and derails multi-step plans. By externalizing the state, the context window becomes merely a view into the current step. If the context overflows, the agent can still recover by reading the external state on the next turn.
