Core Insight
Human working memory: ~4 items (Cowan 2001). The analogy motivates context organization; it does not show that LLMs share the human four-item limit or fatigue. Lost in the Middle studies position-sensitive retrieval in long inputs. Design for constrained cognition.
Relevance to Hermes
- Context management: context-compaction + headroom + scope-recall are engineering responses to bounded cognition
- Knowledge externalization: gbrain exists to move facts from fragile working memory to persistent structure
- 7-role architecture: distributing cognition across specialist agents follows bounded-cognition design
- Skill design: skills should be concise and testable; Cowan’s human working-memory estimate does not set an LLM limit of four attention slots (pre-exec-guard, verification steps)
- Multi-agent delegation: delegating to Alaya/Anchor/Mano keeps each context manageable
