agent memory systems

The persistent playbook is a memory system for agents to compound learning across interactions

Stateful agents require memory systems that persist state across turns. The author's question implicitly assumes this gap.

Post explicitly discusses FAISS, Redis, Pinecone, LlamaIndex as memory substrates for agents. This directly instantiates the concept of how agents preserve state.

Mentions 'memory as real bottleneck behind agent hype' but doesn't explain or address it. Practitioners solving this problem need concrete context/memory patterns—this offers only speculation.
