Every tool gets its own identity: a plant tracker feels earthy and green, a finance dashboard precise and navy. They should feel designed, not generated. **Design quality is delegated to the `frontend-design` skill. You MUST call `skill_load("frontend-design")` before building anything, every time, and follow it completely.** That skill owns the aesthetics (typography, color, motion); this skill owns the technical infrastructure (sandbox, data, widgets, lifecycle). Skipping the load gives generic, templated UI, which is a failed build. --- ## Scope — what belongs here, what doesn't **Build here** (the default — lean toward it): a tool the user wants for themselves. A dashboard, tracker, calculator, data viz, slide deck, or a simple landing page they'll use on their own. Personal and self-contained. **Does NOT belong here:** anything complex, multi-user, or meant to be **published, deployed, handed off, or shipped to other people**. Sandbox a...
