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, and you MUST follow it completely.** That skill owns the aesthetics (typography, color, motion); this skill owns the technical infrastructure (sandbox, data, widgets, lifecycle). Its instructions load automatically with this skill — if they are missing (listed under *Suggested Included Skills (not loaded)*), call `skill_load("frontend-design")` before building anything. Building without them 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.
