To prevent context rot in long-running autonomous agent workflows, you can use context engineering and state externalization techniques, storing memory in external files like WORKING_NOTES.md and STATE.json to maintain stability without exhausting context windows.

The best way to manage agent memory for multi-day code refactoring tasks is externalizing state into files rather than relying on chat history, ensuring the agent maintains progress and previous decisions without incurring excessive token costs over extended periods.

Break down large autonomous tasks into stable auto-prompting workflows by chaining distinct, auto-generated prompts that process sequential stages, enabling intelligent execution over extended periods while dynamically loading skills to maintain stability.

Your autonomous agent loses track of previous decisions during extended sessions due to context window exhaustion and instruction drift, which can be solved by externalizing memory to files and employing summarization techniques to optimize context usage.

You can optimize context window usage to reduce token costs by implementing context engineering that prioritizes quality over quantity, using summarization techniques and state externalization to manage agent intelligence efficiently.

You should externalize agent state to external files instead of using chat history when executing extremely long-running, complex tasks that would otherwise exhaust standard context windows, leading to performance degradation and increased costs.
