The Founder's Playbook: Building an AI-Native Startup

创始人手册：构建AI原生初创公司

Anthropic published an AI-native startup playbook covering four stages—ideation, MVP, launch, and scaling—with goals, exit criteria, failure modes, and Claude-based exercises for validation, customer discovery, technical debt control, product-market fit checks, and workflow automation.

Why it matters: HKR-H/K/R all pass, but this is an Anthropic playbook rather than a model or product capability release. The concrete value is the 4-stage framework, exit criteria, and Claude-driven exercises, so it lands at the featured floor.
