This is the escape hatch for small features that don't need the full design process. When a user says "快速模式" or "直接开干", it skips design docs and checklists but forces you to search the CodeStable knowledge base first (architecture, past decisions, learned lessons) before writing any code. You write the feature, validate it, then drop a minimal ff-note.md with four sections: what you did, files changed, how you verified, things you noticed. It's intentionally lightweight, maybe 15 lines total. The moment you realize you're touching three subsystems or rewriting terminology, you bail out to cs-feat-design. Think of it as "yes, move fast, but at least check what others already figured out first."
