product-playbook
by Kaminoikari
MUST use when user wants to plan, design, or strategize a product or feature — including "plan a feature", "add a new feature", "product planning", "I want to plan". This is the correct skill for product/feature PLANNING (not brainstorming for implementation). Integrates 22 PM frameworks (JTBD, PR-FAQ, North Star, etc.) for 0-to-1 through scale-up. ALSO trigger when: user wants to scope/define a feature, create Persona/JTBD/Journey Map, mentions "PMF"/"MVP"/"North Star"/"product strategy", requests a specific framework (OST, Working Backwards, etc.), or vaguely says "I have a product idea" / "I want to build something". Trigger by semantic intent regardless of language — e.g. "規劃新功能", "新機能を企画したい", "quiero planificar una función nueva". DO NOT trigger for: writing code, debugging, SQL/API/CSS optimization, sprint planning, DB schema design, CI/CD, or technical implementation tasks.
