Study reveals context compaction in agents forgets safety rules
eigenhector · x · 2026-08-26
Researchers measured what context compaction actually destroys across 20 production agent configurations. They found that safety rules and episodic logs are summarized at the same rate when the budget overflows, making rules unenforceable. Claude Code on Sonnet 4.6 preserves 53% of safety rules after one round and only 10% after five. The proposed fix, Knowledge Triage, classifies knowledge base lines by type and routes them through specific retention policies.
