project-brain

Triggers (all require explicit user request — do NOT activate just because a brain/ folder exists): (1) The user wants to set up project-level memory ("set up project brain", "scaffold project context", "init project brain", "建项目脑"). (2) The user is in a directory containing brain/ AND explicitly asks to resume / continue / load the project / check status / "what's the state of this project" / "继续这个项目". (3) The user signals window switch / context compaction ("switch windows", "context's getting full", "I'll head out", "压缩了", "切窗口") — write a HANDOFF before they leave. (4) The user says "update the project brain" / "let's record this" / "更新项目脑" — propose a list with reasons; user approves per item. (5) The user mentions multiple parallel workstreams / 多线程项目 / 多任务并行 — enable Multi-workstream Mode (METHODOLOGY §3.5). Do NOT auto-activate from casual conversation — explicit user request required.
