[frontier] Agent loses track of initial instructions or early conversation context during long-horizon tasks

Implement Episodic State Compression. Do not rely on the context window for long-term state. After every 3-5 turns, use a background LLM call to summarize the current state, completed steps, and remaining goals into a structured State Object, and inject only this object into the next turn's system prompt.

Journey Context:
Developers treat the context window as a perfect memory bank. In reality, as the context window fills, attention mechanisms suffer from the lost in the middle phenomenon, causing the agent to forget its original objective. Simply appending history is a linear trap. Episodic State Compression turns linear history into a bounded, constantly updated state representation.
