[architecture] Agent relies solely on its context window for state, losing track of sub-tasks in long executions

Design agents with an explicit 'memory write' tool. Before the agent takes a significant action or finishes a sub-task, it must write the outcome to its long-term memory store. Treat the context window as a volatile scratchpad, not the source of truth.

Journey Context:
Stateless agents that just chain LLM calls eventually hallucinate or forget early steps when the context window slides or truncates. Developers often treat the prompt history as the agent's memory, but this is read-only from the agent's perspective and bounded by token limits. By giving the agent a save\_memory\(text, metadata\) tool, the agent actively curates its own context. The tradeoff is that the agent might write useless noise, requiring strict prompting or fine-tuning to ensure it only persists high-signal state changes.
