Design engineering system for AI coding agents — ship UI with craft-level quality. Install as an agent skill.
Command
Responsive layout pass covering breakpoints, touch targets, safe areas, and fluid type. Use when the UI has layout or touch issues on mobile/tablet, when adding a new screen that hasn't been tested across viewports, or when the user says "make it responsive" / "fix mobile layout".
Command
Motion design pass — adds purposeful animations or removes excessive ones, respecting MOTIONINTENSITY and the project's animation stack. Use when the user asks to add animation, "make it feel smoother", fix janky transitions, or trim motion that's distracting.
Command
Technical UI audit — a11y, performance, responsive. Produces a prioritized findings table.
Command
Amplify personality — raises layout variance and motion, strengthens typography and one signature detail, without slop. Use when the UI works but feels safe, flat, or "template-y", or when the user says "bolder", "more personality", "more creative", or "make it pop" (still professional).
Command
Write or update the project's durable design brief at .ui-craft/brief.md.
Command
UX copy review across buttons, errors, empty states, and form hints — critiques by default, applies only on request. Use when copy feels vague, generic, or AI-sounding, or when the user says "fix the labels", "improve error messages", or "review the copy".
Command
Color strategy pass — introduces a single accent at 3-5 intentional placements, or reduces an over-colored UI back to 90% neutral. Use when the UI has no color identity, uses blue by default, or is shouting with too many competing accents.
Command
One-shot build pipeline for a complete surface from an outcome recipe — inputs (or defaults) → composition → theme → build order → acceptance bar. Use when the user asks for a whole surface ("build me a dashboard", "I need a landing page") and expects a shippable result, not component-level help.
Command
Design lens critique covering visual hierarchy, clarity, and anti-slop patterns — produces a findings table, no code edits unless asked. Use when the user wants a design review, says "what's wrong with this UI", or needs a second opinion before a handoff or presentation.
Command
Delight pass — adds one or two memorable micro-interactions (copy specificity, hover choreography, state transitions, one signature detail) without decoration or confetti. Use when the UI works but feels generic, or when the user says "make it feel special" / "add some personality".
Command
Reduction pass — cuts content, structure, visuals, and dead code that doesn't answer a user question or drive an action, respecting CRAFTLEVEL. Use when the UI feels cluttered, has too many CTAs, walls of text, or decorative noise, or when the user says "simplify this" / "it feels too busy".
Command
Refactoring pass — extracts repeated Tailwind class combos and markup into components, and lifts magic values into design tokens. Use when the codebase has obvious duplication, hardcoded hex values or pixel sizes, or when the user says "clean this up" / "extract components" / "tokenize styles".
Command
Pre-ship gate — runs detector, verifies brief and tokens, applies the 10-pass finish bar, ranks findings by feedback hierarchy. Use when the user wants to ship, merge, or finalize a surface and needs a verdict (READY / NOT READY / BLOCKED) before committing.
Command
Production-readiness pass — audits and implements the full non-happy-path matrix: loading skeletons, empty states, error messages, partial data, i18n, offline, permissions, and first-run guidance. Use when preparing a surface for production or when the user says "it crashes on empty data" / "there's no loading state"…
Command
Produce a scored heuristic critique of the UI using Nielsen's 10 + 6 design laws + optional persona walkthroughs. Outputs a machine-parseable scorecard plus a 0-100 UsabilityScore (the judged companion to the deterministic UICraftScore).
Command
Final craft pass applying the compound details from the polish checklist — micro-typography, spacing rhythm, hover states, and a signature detail — directly to code. Use when the surface is functionally complete but feels unfinished, or when the user says "polish this" / "it looks generic" / "add the final touches".
Command
Tone down visual noise — lowers variance and motion, simplifies layout and color weight, keeps hierarchy clear. Use when the UI feels loud, busy, or over-designed, or when the user says "quieter", "more restrained", "simpler", or "tone it down".
Command
Redesign an existing site or app without losing what already works — audits the current surface first, classifies what to preserve (brand, IA, SEO, content), picks a refresh/reskin/rebuild scope, then modernizes deliberately. Use when the user says "redesign", "modernize this site", "refresh the UI", "make this look…
Command
Record a learned design constraint from a correction into the project brief.
Command
Full spec-driven pipeline — walks brief → tokens → shape (spec) → craft (build) → converge → ship in one guided run. Writes .ui-craft/spec.md. Run when starting a net-new surface from scratch.
Command
Wireframe-first pass — outputs an ASCII layout + state list + content inventory + question list before any code. Use when starting a new screen from scratch or when the user's brief is still ambiguous.
Command
Front door. Reads the current project (framework, tokens, brief, spec, harness) and reports what ui-craft can do right now, then routes you to the right next step. Run this first if you're new or unsure where to begin. No code changes.
Command
Audit or establish the project's 3-layer token spine.
Command
Typography pass covering font choice, modular scale, tracking, leading, weight hierarchy, and micro-typography details. Use when fonts feel generic (default Inter with no reason), the scale is ad hoc, hierarchy is flat, or the user says "fix the typography" / "the text doesn't feel right".
