Context Window Management

Surviving Long Horizons

Even with 1-million token context windows, an agent running for hours will run out of space or suffer from the "Lost in the Middle" phenomenon (where it ignores instructions in the middle of a huge prompt).

Compaction & Distillation

When the context grows too large, the Orchestrator pauses the agent, passes the history to a summarization model, and replaces the massive history block with a dense summary.

# Before Compaction: [Msg1 ... Msg100] (50k tokens)
# After Compaction: [Summary_Msg, Msg95... Msg100] (2k tokens)

⭐ +150 XP

Execute context compaction and recursive summarization on an agent's conversational trajectory to prevent token overflow.
