Add `coreMemory.refreshAtContextPercent` config option to re-inject core memories when context usage exceeds a threshold. This counters the "lost in the middle" phenomenon documented by Liu et al. (2023). Implementation: - Extend before_agent_start hook event with context usage info - Pass contextWindowTokens and estimatedUsedTokens to hooks - Track mid-session refresh per session to prevent over-refreshing - Clear refresh tracking on compaction - Add comprehensive tests Based on research: Liu et al., "Lost in the Middle: How Language Models Use Long Contexts" (Stanford, 2023) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
