What problem does it solve? Building UI screens without a consistent design system leads to improvised layouts, brand drift, and unverified visual output. This Skill enforces a structured design method that resolves an effective rule set before writing code and validates the result with scoring and rendering gates. ## Core Features & Use Cases - Rule Resolution Before Code: Compiles an effective rule set from grammar, brand recipe, domain, page, profile, and lock constraints via ss-resolve, recorded in .styleseed/effective-rules.md and a provenance manifest. - Composed Design Authority: Applies a fixed authority order (core invariants, grammar, surface adapter, brand recipe, profile, lock) so conflicts resolve predictably instead of ad hoc. - Code and Pixel Gates: Runs /ss-score until the implementation scores at least 80, then /ss-verify to inspect rendered viewports and states before presenting results. - Use Case: A developer building a SaaS dashboard invokes the Skill to compose the operations-console grammar with locked brand tokens, implement the screen, and iterate through scoring and visual verification until both gates pass. ## Quick Start Ask the agent to build a dashboard screen using the ss-build method with your existing STYLESEED.md configuration.
