tool-foundation-sprint-differentiation skillA
tool-foundation-sprint-differentiation is agent-read markdown (skill) from product-on-purpose/pm-skills: Day 1 afternoon move of a Foundation Sprint. Converts the morning's Basics frame into a defensible strategic position by scoring differentiator candidates against customer-perceived value, choosing two committed differentiators, plotting alternatives on a 2x2 chart, writing decision principles, and producing a one-page Mini Manifesto. Use after Basics is signed; before Approach Options the next morning..
