Interface craft

Interface Craft

By ProductionOS Design

A toolkit for building polished, animated interfaces. Write animations you can read like a script, then tune them with live controls.

Inputs

Parameter	Values	Default	Description
target	path or context	cwd	What to operate on

Skills

Skill	When to Use	Invoke
Motion System	Writing or refactoring multi-stage animations into a human-readable DSL	/interface-craft storyboard or describe an animation
DialKit	Adding live control panels to tune animation/style values	/interface-craft finetune-control or mention dials/sliders/controls
Design Evaluator	Systematic UI critique of a screenshot, component, or page	/interface-craft critique or paste a screenshot for review

Quick Start

Motion System

Turn any animation into a readable storyboard with named timing, config objects, and stage-driven sequencing:

/* ─────────────────────────────────────────────────────────
 * ANIMATION STORYBOARD
 *
 *    0ms   waiting for scroll into view
 *  300ms   card fades in, scale 0.85 → 1.0
 *  900ms   heading highlights
 * 1500ms   rows slide up (staggered 200ms)
 * ───────────────────────────────────────────────────────── */

const TIMING = {
  cardAppear:  300,   // card fades in
  heading:     900,   // heading highlights
  rows:        1500,  // rows start staggering
};

See motion-system.md for the full pattern spec.

DialKit

Generate live control panels for tuning values in real time:

const params = useDialKit('Card', {
  scale: [1, 0.5, 2],
  blur: [0, 0, 100],
  spring: { type: 'spring', visualDuration: 0.3, bounce: 0.2 },
})

See finetune-control.md for all control types and patterns.

Sub-Skill Routing

When the user invokes /interface-craft:

1. With storyboard argument or animation-related context → Load and follow motion-system.md
2. With finetune-control argument or control-panel-related context → Load and follow finetune-control.md
3. With critique argument, a pasted image, or review-related context → Load and follow design-evaluator.md
4. With a file path → Read the file, detect whether it needs storyboard refactoring, finetune-control controls, or a design critique, and apply the appropriate skill
5. With a plain-English description of an animation → Use motion-system to write it
6. Ambiguous → Ask which skill to use

Design Principles

1. Readable over clever — Anyone should be able to scan the top of a file and understand the animation sequence without reading implementation code
2. Tunable by default — Every value that affects timing or appearance should be a named constant, trivially adjustable
3. Data-driven — Repeated elements use arrays and .map(), not copy-pasted blocks
4. Stage-driven — A single integer state drives the entire sequence; no scattered boolean flags
5. Spring-first — Prefer spring physics over duration-based easing for natural motion

Guardrails

1. Do not silently change scope.
2. Prefer concrete outputs over abstract descriptions.
3. Keep scope faithful to user intent.
4. Verify results before concluding.
