This is a comprehensive PM toolkit packed into a Claude skill. It covers six core domains from strategy to metrics, includes 30+ frameworks like RICE and Jobs-to-be-Done, and calculates 32 SaaS metrics with formulas built in. You get 12 templates for PRDs, launch checklists, and competitive analysis. It's built for structured product work rather than brainstorming, so reach for it when you need to score opportunities, build roadmaps, or calculate LTV:CAC ratios. The scope is ambitious but well-organized. Pure Markdown with no scripts means it's portable across AI coding tools. Best for PMs or founders who want proven frameworks at their fingertips without hunting through docs.
