UI Craft

Use the project's visual and copy authorities, shipped primitive inventory, and real runtime behavior. Preserve keyboard/focus operation, supported states, meaningful labels, contrast, reduced motion, and token ownership.

For a small edit, inspect the affected component/state and reuse existing decisions. A new surface or substantial redesign may need a short user job, scene, register, or visual dials when those resolve an actual design choice; they are not required artifacts for every tweak.

• Read the relevant design/token/copy contract. When generated documentation and runtime tokens disagree, follow the project's canonical-source rule and regenerate through its owning tool.
• Reuse existing primitives and supported states. Do not invent controls, metrics, helper copy, brand variants, or host chrome to satisfy a prototype.
• Match verification to changed interaction/visual behavior: render the affected states, check keyboard/focus where interaction changes, and compare a named reference when required. Reuse current evidence; whole-surface matrices and all-breakpoint sweeps need corresponding scope.
• Review actual hierarchy, overflow, token drift, misleading interaction, and accessibility defects. Avoid a fixed scorecard that turns subjective preferences into universal merge blockers.
• Update design authorities only for an actual token/pattern change, through their generator when owned by codegen. A missing optional reference does not justify scaffolding a new design system.

References by Need

Use the matching section and its necessary dependencies. The table is a lookup, not a list to load in full. assets/state-matrix.md, assets/pre-ship-checklist.md, and assets/ui-audit-template.md are optional working formats for substantial design/audit tasks; ordinary changes can use concise evidence.

Helpers

Resolve these from the actual skill directory (<ui-craft-dir>); run only for the question in scope:

• node <ui-craft-dir>/scripts/check-contrast.mjs — read-only contrast calculation for changed rendered colors.
• node <ui-craft-dir>/scripts/detect-token-drift.mjs — read-only drift scan; use project lint/codegen evidence when it already owns the invariant.
• python3 <ui-craft-dir>/scripts/validate-metadata.py — authoring metadata validation.

Follow explicit user decisions and project authorities for trade-offs. Record material limitations honestly; do not force a scene interview, design audit, or another approval solely because this skill was used.
