Pi Coding Agent users seek session memory

This is less a launch story than a design signal: Pi exposes primitives, not a one-click memory layer, so users looking for durable recall have to compose it themselves. The Reddit thread and official Pi site and README show the intended model: sessions are trees, /compact is lossy, and context is shaped by files and extensions. AGENTS.md is the easiest durable hook because Pi loads it from global, parent, and current directories at startup. SYSTEM.md, prompt templates, and skills give repeatable project instructions without retyping setup every session. Session trees plus /resume, /tree, and /fork help with branching and replay, but they are not shared memory across fresh sessions. Extensions can inject messages, filter history, and build RAG or long-term memory, which is the actual path to auto-memory.
