Use when the user asks "what's it called when…", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one. +--- + +# Animation Vocabulary + +Turn a vague description of a motion or effect into the precise term, so the user knows what to ask for. + +## Quick Start + +The user describes an effect loosely. You return the matching term(s) in this format: + +``` +**Stagger** — Animate several items one after another with a small delay between each, creating a cascade. +``` + +If several terms could fit, list the best match first, then 1–2 alternates with a one-line note on how they differ. + +## Instructions + +1. **Read for intent, not keywords.** Users describe what they *see* or *feel* ("springy", "slides off", "draws itself in"), not the technical name. Map the sensation to the glossary below. +2. **Quote the glossary verbatim.** Its descriptions are authoritative — use them as-is, don't paraphrase. +3. **Disambiguate close terms.** When two compete (*Clip-path* vs *Mask*, *Pop in* vs *Bounce*, *Shared element transition* vs *Layout animation*), contrast them so the user can pick. +4. **When nothing matches exactly,** name the closest term and say plainly it's an approximation, or describe the effect in the glossary's vocabulary (e.g. "that's a *stagger* of *scale-in* entrances"). +5. **Stay within this glossary.** If a term genuinely isn't here, say so rather than inventing one — though you may explain the concept using these words. +6. **Keep it tight.** A naming question wants a name, not an essay.

For example, making the same rectangle bigger and smaller. +- **Morph** — One shape smoothly turns into another shape, e.g. Dynamic Island. +- **Shared element transition** — An element travels and transforms from one position into another, like a thumbnail expanding into a card. +- **Layout animation** — When an element's size or position changes, it animates to the new spot instead of snapping. +- **Accordion / Collapse** — A section smoothly expands and collapses its height to show or hide content. +- **Direction-aware transition** — Content slides one way going forward and the opposite way going back, so navigation has a sense of direction. + +### Scroll — motion tied to scrolling or navigating between views +- **Scroll reveal** — Elements fade or slide into place as they enter the viewport. +- **Scroll-driven animation** — An animation whose progress is tied directly to scroll position. +- **Parallax** — Background and foreground move at different speeds while scrolling, creating depth. +- **Page transition** — An animation that plays when navigating from one page or route to another. +- **View transition** — The browser morphs between two states or pages, connecting shared elements. + +### Feedback & Interaction — responding to the user's actions +- **Hover effect** — Visual change when the cursor moves over an element. +- **Press / Tap feedback** — A subtle scale-down when an element is clicked, so it feels physical. +- **Hold to confirm** — A progress effect that fills up while the user holds a button. +- **Drag** — Moving an element by grabbing it, often with momentum when released. +- **Drag to reorder** — Dragging items in a list to rearrange them, while the others shift to make room. +- **Swipe to dismiss** — Dragging an element off-screen to close it, like a drawer or toast. +- **Rubber-banding** — Resistance and snap-back when you drag past a boundary (the iOS overscroll feel). +- **Shake / Wiggle** — A quick side-to-side jitter signaling an error or rejected input. +- **Ripple** — A circle expanding from the point of a tap, confirming the press. + +### Easing — how speed changes over an animation +- **Easing** — The rate at which an animation speeds up or slows down. +- **Ease-out** — Starts fast, ends slow. The default for most UI and anything responding to the user. +- **Ease-in** — Starts slow, ends fast. Usually avoided; can feel sluggish. +- **Ease-in-out** — Slow, fast, slow. Good for elements already on screen moving from A to B. +- **Linear** — Constant speed. Avoid for UI; reserve for spinners or marquees. +- **Cubic-bezier** — A custom easing curve you define for precise control. +- **Asymmetric easing** — A curve that accelerates and decelerates at different rates. Feels more alive than a symmetric one. + +### Spring Animations — physics-based motion as an alternative to fixed-duration easing +- **Spring** — Motion driven by physics (tension, mass, damping) rather than a set duration. +- **Stiffness / Tension** — How strongly the spring pulls toward its target. Higher feels snappier. +- **Damping** — How quickly a spring settles. Lower damping means more bounce and oscillation. +- **Mass** — How heavy the animated element feels. More mass makes it slower and more sluggish. +- **Bounce** — A spring that overshoots and settles, adding playfulness. +- **Perceptual duration** — How long a spring feels finished, even though it keeps micro-settling underneath. +- **Momentum** — Motion that carries velocity, especially after a drag or interruption. +- **Velocity** — How fast and in which direction an element is moving. A spring carries it into the next animation when interrupted, so a flicked element keeps its speed. +- **Interruptible animation** — An animation that can be smoothly redirected mid-flight instead of finishing first. + +### Looping & Ambient Motion — animations that run on their own +- **Marquee** — Text or content that scrolls continuously in a loop. +- **Loop** — An animation that repeats, a set number of times or infinitely. +- **Alternate (yoyo)** — A loop that plays forward then reverses each iteration, instead of jumping back to the start. +- **Orbit** — An element circling around another in a continuous path. +- **Pulse** — A gentle repeating scale or opacity change to draw attention. +- **Float** — A gentle, continuous up-and-down drift that makes a static element feel alive and weightless. +- **Idle animation** — Subtle motion that plays while an element is just sitting there, waiting to be interacted with. + +### Polish & Effects — the small touches that separate good from great +- **Blur** — A blur filter used to soften an element or mask tiny imperfections. +- **Clip-path** — Clipping an element to a shape, used for reveals, masks, and before/after sliders. +- **Mask** — Hiding or revealing parts of an element using a shape or gradient — like clip-path, but with soft, fadeable edges. +- **Before / after slider** — A draggable divider that wipes between two overlaid images to compare them. +- **Line drawing** — An SVG path that draws itself in, like an invisible pen tracing it. +- **Text morph** — Text that animates character by character when it changes, drawing attention to the new value. +- **Skeleton / Shimmer** — A placeholder with a moving sheen shown while content loads. +- **Number ticker** — Digits rolling or counting up to a value. +- **Tabular numbers** — Fixed-width digits so numbers don't shift around as they change. Essential for tickers, timers, and counters. +- **Typewriter** — Text appearing one character at a time, as if being typed. + +### Performance — what keeps motion smooth instead of stuttering +- **Frame rate (FPS)** — Frames drawn per second. 60fps is the baseline for smooth motion; 120fps on newer displays. +- **Jank** — Visible stutter when the browser drops frames because it can't keep up with the animation. +- **Dropped frame** — A frame the browser missed its deadline to draw, causing a tiny hitch in motion. +- **Compositing** — Letting the GPU move or fade an element on its own layer without redoing layout or paint. +- **will-change** — A CSS hint that an element is about to animate, so the browser can promote it to its own layer ahead of time. +- **Layout thrashing** — Animating properties like width, height, top, or left that force the browser to recalculate layout every frame, causing jank. + +### Principles to Know — concepts that guide when and how to animate +- **Purposeful animation** — Motion should serve a function — orient, give feedback, show relationships — not just decorate. +- **Anticipation** — A small wind-up in the opposite direction before a move, hinting at what's about to happen. +- **Follow-through** — Parts of an element keep moving and settle slightly after the main motion stops, adding weight. +- **Squash & stretch** — Deforming an element as it moves to convey weight, speed, and flexibility. +- **Perceived performance** — The right animation makes an interface feel faster, even when it isn't. +- **Frequency of use** — The more often a user sees an animation, the shorter and subtler it should be. +- **Spatial consistency** — Animating so an element keeps its identity and position across states, so users never lose track of where things went. +- **Hardware acceleration** — Animating transform and opacity lets the GPU keep motion smooth. +- **Reduced motion** — Respecting the user's prefers-reduced-motion setting by toning down or removing motion. diff --git a/.agents/skills/emil-design-eng/SKILL.md b/.agents/skills/emil-design-eng/SKILL.md new file mode 100644 index 0000000..4911235 --- /dev/null +++ b/.agents/skills/emil-design-eng/SKILL.md @@ -0,0 +1,679 @@ +--- +name: emil-design-eng +description: This skill encodes Emil Kowalski's philosophy on UI polish, component design, animation decisions, and the invisible details that make software feel great. +--- + +# Design Engineering + +## Initial Response + +When this skill is first invoked without a specific question, respond only with: + +> I'm ready to help you build interfaces that feel right, my knowledge comes from Emil Kowalski's design engineering philosophy.

The "Why" column briefly explains the reasoning. + +## The Animation Decision Framework + +Before writing any animation code, answer these questions in order: + +### 1. Should this animate at all? + +**Ask:** How often will users see this animation? + +| Frequency | Decision | +| ----------------------------------------------------------- | ---------------------------- | +| 100+ times/day (keyboard shortcuts, command palette toggle) | No animation. Ever. | +| Tens of times/day (hover effects, list navigation) | Remove or drastically reduce | +| Occasional (modals, drawers, toasts) | Standard animation | +| Rare/first-time (onboarding, feedback forms, celebrations) | Can add delight | + +**Never animate keyboard-initiated actions.** These actions are repeated hundreds of times daily. Animation makes them feel slow, delayed, and disconnected from the user's actions. + +Raycast has no open/close animation. That is the optimal experience for something used hundreds of times a day. + +### 2. What is the purpose? + +Every animation must have a clear answer to "why does this animate?" + +Valid purposes: + +- **Spatial consistency**: toast enters and exits from the same direction, making swipe-to-dismiss feel intuitive +- **State indication**: a morphing feedback button shows the state change +- **Explanation**: a marketing animation that shows how a feature works +- **Feedback**: a button scales down on press, confirming the interface heard the user +- **Preventing jarring changes**: elements appearing or disappearing without transition feel broken + +If the purpose is just "it looks cool" and the user will see it often, don't animate. + +### 3. What easing should it use? + +Is the element entering or exiting? + Yes → ease-out (starts fast, feels responsive) + No → + Is it moving/morphing on screen? + Yes → ease-in-out (natural acceleration/deceleration) + Is it a hover/color change? + Yes → ease + Is it constant motion (marquee, progress bar)? + Yes → linear + Default → ease-out + +**Critical: use custom easing curves.** The built-in CSS easings are too weak. They lack the punch that makes animations feel intentional. + +```css +/* Strong ease-out for UI interactions */ +--ease-out: cubic-bezier(0.23, 1, 0.32, 1); + +/* Strong ease-in-out for on-screen movement */ +--ease-in-out: cubic-bezier(0.77, 0, 0.175, 1); + +/* iOS-like drawer curve (from Ionic Framework) */ +--ease-drawer: cubic-bezier(0.32, 0.72, 0, 1); +``` + +**Never use ease-in for UI animations.** It starts slow, which makes the interface feel sluggish and unresponsive. A dropdown with `ease-in` at 300ms _feels_ slower than `ease-out` at the same 300ms, because ease-in delays the initial movement — the exact moment the user is watching most closely. + +**Easing curve resources:** Don't create curves from scratch. Use [easing.dev](https://easing.dev/) or [easings.co](https://easings.co/) to find stronger custom variants of standard easings. + +### 4. How fast should it be? + +| Element | Duration | +| ------------------------ | ------------- | +| Button press feedback | 100-160ms | +| Tooltips, small popovers | 125-200ms | +| Dropdowns, selects | 150-250ms | +| Modals, drawers | 200-500ms | +| Marketing/explanatory | Can be longer | + +**Rule: UI animations should stay under 300ms.** A 180ms dropdown feels more responsive than a 400ms one. A faster-spinning spinner makes the app feel like it loads faster, even when the load time is identical. + +### Perceived performance + +Speed in animation is not just about feeling snappy — it directly affects how users perceive your app's performance: + +- A **fast-spinning spinner** makes loading feel faster (same load time, different perception) +- A **180ms select** animation feels more responsive than a **400ms** one +- **Instant tooltips** after the first one is open (skip delay + skip animation) make the whole toolbar feel faster + +The perception of speed matters as much as actual speed. Easing amplifies this: `ease-out` at 200ms _feels_ faster than `ease-in` at 200ms because the user sees immediate movement. + +## Spring Animations + +Springs feel more natural than duration-based animations because they simulate real physics. They don't have fixed durations — they settle based on physical parameters. + +### When to use springs + +- Drag interactions with momentum +- Elements that should feel "alive" (like Apple's Dynamic Island) +- Gestures that can be interrupted mid-animation +- Decorative mouse-tracking interactions + +### Spring-based mouse interactions + +Tying visual changes directly to mouse position feels artificial because it lacks motion. Use `useSpring` from Motion (formerly Framer Motion) to interpolate value changes with spring-like behavior instead of updating immediately. + +```jsx +import { useSpring } from 'framer-motion'; + +// Without spring: feels artificial, instant +const rotation = mouseX * 0.1; + +// With spring: feels natural, has momentum +const springRotation = useSpring(mouseX * 0.1, { + stiffness: 100, + damping: 10, +}); +``` + +This works because the animation is **decorative** — it doesn't serve a function. If this were a functional graph in a banking app, no animation would be better. Know when decoration helps and when it hinders. + +### Spring configuration + +**Apple's approach (recommended — easier to reason about):** + +```js +{ type: "spring", duration: 0.5, bounce: 0.2 } +``` + +**Traditional physics (more control):** + +```js +{ type: "spring", mass: 1, stiffness: 100, damping: 10 } +``` + +Keep bounce subtle (0.1-0.3) when used. Avoid bounce in most UI contexts. Use it for drag-to-dismiss and playful interactions. + +### Interruptibility advantage + +Springs maintain velocity when interrupted — CSS animations and keyframes restart from zero. This makes springs ideal for gestures users might change mid-motion. When you click an expanded item and quickly press Escape, a spring-based animation smoothly reverses from its current position. + +## Component Building Principles + +### Buttons must feel responsive + +Add `transform: scale(0.97)` on `:active`. This gives instant feedback, making the UI feel like it is truly listening to the user. + +```css +.button { + transition: transform 160ms ease-out; +} + +.button:active { + transform: scale(0.97); +} +``` + +This applies to any pressable element. The scale should be subtle (0.95-0.98). + +### Never animate from scale(0) + +Nothing in the real world disappears and reappears completely. Elements animating from `scale(0)` look like they come out of nowhere. + +Start from `scale(0.9)` or higher, combined with opacity. Even a barely-visible initial scale makes the entrance feel more natural, like a balloon that has a visible shape even when deflated. + +```css +/* Bad */ +.entering { + transform: scale(0); +} + +/* Good */ +.entering { + transform: scale(0.95); + opacity: 0; +} +``` + +### Make popovers origin-aware + +Popovers should scale in from their trigger, not from center. The default `transform-origin: center` is wrong for almost every popover. **Exception: modals.** Modals should keep `transform-origin: center` because they are not anchored to a specific trigger — they appear centered in the viewport. + +```css +/* Radix UI */ +.popover { + transform-origin: var(--radix-popover-content-transform-origin); +} + +/* Base UI */ +.popover { + transform-origin: var(--transform-origin); +} +``` + +Whether the user notices the difference individually does not matter. In the aggregate, unseen details become visible. They compound. + +### Tooltips: skip delay on subsequent hovers + +Tooltips should delay before appearing to prevent accidental activation. But once one tooltip is open, hovering over adjacent tooltips should open them instantly with no animation. This feels faster without defeating the purpose of the initial delay. + +```css +.tooltip { + transition: transform 125ms ease-out, opacity 125ms ease-out; + transform-origin: var(--transform-origin); +} + +.tooltip[data-starting-style], +.tooltip[data-ending-style] { + opacity: 0; + transform: scale(0.97); +} + +/* Skip animation on subsequent tooltips */ +.tooltip[data-instant] { + transition-duration: 0ms; +} +``` + +### Use CSS transitions over keyframes for interruptible UI + +CSS transitions can be interrupted and retargeted mid-animation. Keyframes restart from zero. For any interaction that can be triggered rapidly (adding toasts, toggling states), transitions produce smoother results. + +```css +/* Interruptible - good for UI */ +.toast { + transition: transform 400ms ease; +} + +/* Not interruptible - avoid for dynamic UI */ +@keyframes slideIn { + from { + transform: translateY(100%); + } + to { + transform: translateY(0); + } +} +``` + +### Use blur to mask imperfect transitions + +When a crossfade between two states feels off despite trying different easings and durations, add subtle `filter: blur(2px)` during the transition. + +**Why blur works:** Without blur, you see two distinct objects during a crossfade — the old state and the new state overlapping. This looks unnatural. Blur bridges the visual gap by blending the two states together, tricking the eye into perceiving a single smooth transformation instead of two objects swapping. + +Combine blur with scale-on-press (`scale(0.97)`) for a polished button state transition: + +```css +.button { + transition: transform 160ms ease-out; +} + +.button:active { + transform: scale(0.97); +} + +.button-content { + transition: filter 200ms ease, opacity 200ms ease; +} + +.button-content.transitioning { + filter: blur(2px); + opacity: 0.7; +} +``` + +Keep blur under 20px. Heavy blur is expensive, especially in Safari. + +### Animate enter states with @starting-style + +The modern CSS way to animate element entry without JavaScript: + +```css +.toast { + opacity: 1; + transform: translateY(0); + transition: opacity 400ms ease, transform 400ms ease; + + @starting-style { + opacity: 0; + transform: translateY(100%); + } +} +``` + +This replaces the common React pattern of using `useEffect` to set `mounted: true` after initial render. Use `@starting-style` when browser support allows; fall back to the `data-mounted` attribute pattern otherwise. + +```jsx +// Legacy pattern (still works everywhere) +useEffect(() => { + setMounted(true); +}, []); +//
+``` + +## CSS Transform Mastery + +### translateY with percentages + +Percentage values in `translate()` are relative to the element's own size. Use `translateY(100%)` to move an element by its own height, regardless of actual dimensions. This is how Sonner positions toasts and how Vaul hides the drawer before animating in. + +```css +/* Works regardless of drawer height */ +.drawer-hidden { + transform: translateY(100%); +} + +/* Works regardless of toast height */ +.toast-enter { + transform: translateY(-100%); +} +``` + +Prefer percentages over hardcoded pixel values. They are less error-prone and adapt to content. + +### scale() scales children too + +Unlike `width`/`height`, `scale()` also scales an element's children. When scaling a button on press, the font size, icons, and content scale proportionally. This is a feature, not a bug. + +### 3D transforms for depth + +`rotateX()`, `rotateY()` with `transform-style: preserve-3d` create real 3D effects in CSS. Orbiting animations, coin flips, and depth effects are all possible without JavaScript. + +```css +.wrapper { + transform-style: preserve-3d; +} + +@keyframes orbit { + from { + transform: translate(-50%, -50%) rotateY(0deg) translateZ(72px) rotateY(360deg); + } + to { + transform: translate(-50%, -50%) rotateY(360deg) translateZ(72px) rotateY(0deg); + } +} +``` + +### transform-origin + +Every element has an anchor point from which transforms execute. The default is center. Set it to match where the trigger lives for origin-aware interactions. + +## clip-path for Animation + +`clip-path` is not just for shapes. It is one of the most powerful animation tools in CSS. + +### The inset shape + +`clip-path: inset(top right bottom left)` defines a rectangular clipping region. Each value "eats" into the element from that side. + +```css +/* Fully hidden from right */ +.hidden { + clip-path: inset(0 100% 0 0); +} + +/* Fully visible */ +.visible { + clip-path: inset(0 0 0 0); +} + +/* Reveal from left to right */ +.overlay { + clip-path: inset(0 100% 0 0); + transition: clip-path 200ms ease-out; +} +.button:active .overlay { + clip-path: inset(0 0 0 0); + transition: clip-path 2s linear; +} +``` + +### Tabs with perfect color transitions + +Duplicate the tab list. Style the copy as "active" (different background, different text color). Clip the copy so only the active tab is visible. Animate the clip on tab change. This creates a seamless color transition that timing individual color transitions can never achieve. + +### Hold-to-delete pattern + +Use `clip-path: inset(0 100% 0 0)` on a colored overlay. On `:active`, transition to `inset(0 0 0 0)` over 2s with linear timing. On release, snap back with 200ms ease-out. Add `scale(0.97)` on the button for press feedback. + +### Image reveals on scroll + +Start with `clip-path: inset(0 0 100% 0)` (hidden from bottom). Animate to `inset(0 0 0 0)` when the element enters the viewport. Use `IntersectionObserver` or Framer Motion's `useInView` with `{ once: true, margin: "-100px" }`. + +### Comparison sliders + +Overlay two images. Clip the top one with `clip-path: inset(0 50% 0 0)`. Adjust the right inset value based on drag position. No extra DOM elements needed, fully hardware-accelerated. + +## Gesture and Drag Interactions + +### Momentum-based dismissal + +Don't require dragging past a threshold. Calculate velocity: `Math.abs(dragDistance) / elapsedTime`. If velocity exceeds ~0.11, dismiss regardless of distance. A quick flick should be enough. + +```js +const timeTaken = new Date().getTime() - dragStartTime.current.getTime(); +const velocity = Math.abs(swipeAmount) / timeTaken; + +if (Math.abs(swipeAmount) >= SWIPE_THRESHOLD || velocity > 0.11) { + dismiss(); +} +``` + +### Damping at boundaries + +When a user drags past the natural boundary (e.g., dragging a drawer up when already at top), apply damping. The more they drag, the less the element moves. Things in real life don't suddenly stop; they slow down first. + +### Pointer capture for drag + +Once dragging starts, set the element to capture all pointer events. This ensures dragging continues even if the pointer leaves the element bounds. + +### Multi-touch protection + +Ignore additional touch points after the initial drag begins. Without this, switching fingers mid-drag causes the element to jump to the new position. + +```js +function onPress() { + if (isDragging) return; + // Start drag... +} +``` + +### Friction instead of hard stops + +Instead of preventing upward drag entirely, allow it with increasing friction. It feels more natural than hitting an invisible wall. + +## Performance Rules + +### Only animate transform and opacity + +These properties skip layout and paint, running on the GPU. Animating `padding`, `margin`, `height`, or `width` triggers all three rendering steps. + +### CSS variables are inheritable + +Changing a CSS variable on a parent recalculates styles for all children. In a drawer with many items, updating `--swipe-amount` on the container causes expensive style recalculation. Update `transform` directly on the element instead. + +```js +// Bad: triggers recalc on all children +element.style.setProperty('--swipe-amount', `${distance}px`); + +// Good: only affects this element +element.style.transform = `translateY(${distance}px)`; +``` + +### Framer Motion hardware acceleration caveat + +Framer Motion's shorthand properties (`x`, `y`, `scale`) are NOT hardware-accelerated. They use `requestAnimationFrame` on the main thread. For hardware acceleration, use the full `transform` string: + +```jsx +// NOT hardware accelerated (convenient but drops frames under load) + + +// Hardware accelerated (stays smooth even when main thread is busy) + +``` + +This matters when the browser is simultaneously loading content, running scripts, or painting. At Vercel, the dashboard tab animation used Shared Layout Animations and dropped frames during page loads. Switching to CSS animations (off main thread) fixed it. + +### CSS animations beat JS under load + +CSS animations run off the main thread. When the browser is busy loading a new page, Framer Motion animations (using `requestAnimationFrame`) drop frames. CSS animations remain smooth. Use CSS for predetermined animations; JS for dynamic, interruptible ones. + +### Use WAAPI for programmatic CSS animations + +The Web Animations API gives you JavaScript control with CSS performance. Hardware-accelerated, interruptible, and no library needed. + +```js +element.animate([{ clipPath: 'inset(0 0 100% 0)' }, { clipPath: 'inset(0 0 0 0)' }], { + duration: 1000, + fill: 'forwards', + easing: 'cubic-bezier(0.77, 0, 0.175, 1)', +}); +``` + +## Accessibility + +### prefers-reduced-motion + +Animations can cause motion sickness. Reduced motion means fewer and gentler animations, not zero. Keep opacity and color transitions that aid comprehension. Remove movement and position animations. + +```css +@media (prefers-reduced-motion: reduce) { + .element { + animation: fade 0.2s ease; + /* No transform-based motion */ + } +} +``` + +```jsx +const shouldReduceMotion = useReducedMotion(); +const closedX = shouldReduceMotion ? 0 : '-100%'; +``` + +### Touch device hover states + +```css +@media (hover: hover) and (pointer: fine) { + .element:hover { + transform: scale(1.05); + } +} +``` + +Touch devices trigger hover on tap, causing false positives. Gate hover animations behind this media query. + +## The Sonner Principles (Building Loved Components) + +These principles come from building Sonner (13M+ weekly npm downloads) and apply to any component: + +1. **Developer experience is key.** No hooks, no context, no complex setup. Insert `` once, call `toast()` from anywhere. The less friction to adopt, the more people will use it. + +2. **Good defaults matter more than options.** Ship beautiful out of the box. Most users never customize. The default easing, timing, and visual design should be excellent. + +3. **Naming creates identity.** "Sonner" (French for "to ring") feels more elegant than "react-toast". Sacrifice discoverability for memorability when appropriate. + +4. **Handle edge cases invisibly.** Pause toast timers when the tab is hidden. Fill gaps between stacked toasts with pseudo-elements to maintain hover state. Capture pointer events during drag. Users never notice these, and that is exactly right. + +5. **Use transitions, not keyframes, for dynamic UI.** Toasts are added rapidly. Keyframes restart from zero on interruption. Transitions retarget smoothly. + +6. **Build a great documentation site.** Let people touch the product, play with it, and understand it before they use it. Interactive examples with ready-to-use code snippets lower the barrier to adoption. + +### Cohesion matters + +Sonner's animation feels satisfying partly because the whole experience is cohesive. The easing and duration fit the vibe of the library. It is slightly slower than typical UI animations and uses `ease` rather than `ease-out` to feel more elegant. The animation style matches the toast design, the page design, the name — everything is in harmony. + +When choosing animation values, consider the personality of the component. A playful component can be bouncier. A professional dashboard should be crisp and fast. Match the motion to the mood. + +### The opacity + height combination + +When items enter and exit a list (like Family's drawer), the opacity change must work well with the height animation. This is often trial and error. There is no formula — you adjust until it feels right. + +### Review your work the next day + +Review animations with fresh eyes. You notice imperfections the next day that you missed during development. Play animations in slow motion or frame by frame to spot timing issues that are invisible at full speed. + +### Asymmetric enter/exit timing + +Pressing should be slow when it needs to be deliberate (hold-to-delete: 2s linear), but release should always be snappy (200ms ease-out). This pattern applies broadly: slow where the user is deciding, fast where the system is responding. + +```css +/* Release: fast */ +.overlay { + transition: clip-path 200ms ease-out; +} + +/* Press: slow and deliberate */ +.button:active .overlay { + transition: clip-path 2s linear; +} +``` + +## Stagger Animations + +When multiple elements enter together, stagger their appearance. Each element animates in with a small delay after the previous one. This creates a cascading effect that feels more natural than everything appearing at once. + +```css +.item { + opacity: 0; + transform: translateY(8px); + animation: fadeIn 300ms ease-out forwards; +} + +.item:nth-child(1) { + animation-delay: 0ms; +} +.item:nth-child(2) { + animation-delay: 50ms; +} +.item:nth-child(3) { + animation-delay: 100ms; +} +.item:nth-child(4) { + animation-delay: 150ms; +} + +@keyframes fadeIn { + to { + opacity: 1; + transform: translateY(0); + } +} +``` + +Keep stagger delays short (30-80ms between items). Long delays make the interface feel slow. Stagger is decorative — never block interaction while stagger animations are playing. + +## Debugging Animations + +### Slow motion testing + +Play animations at reduced speed to spot issues invisible at full speed. Temporarily increase duration to 2-5x normal, or use browser DevTools animation inspector to slow playback. + +Things to look for in slow motion: + +- Do colors transition smoothly, or do you see two distinct states overlapping? +- Does the easing feel right, or does it start/stop abruptly? +- Is the transform-origin correct, or does the element scale from the wrong point? +- Are multiple animated properties (opacity, transform, color) in sync? + +### Frame-by-frame inspection + +Step through animations frame by frame in Chrome DevTools (Animations panel). This reveals timing issues between coordinated properties that you cannot see at full speed. + +### Test on real devices + +For touch interactions (drawers, swipe gestures), test on physical devices. Connect your phone via USB, visit your local dev server by IP address, and use Safari's remote devtools. The Xcode Simulator is an alternative but real hardware is better for gesture testing. + +## Review Checklist + +When reviewing UI code, check for: + +| Issue | Fix | +| ------------------------------------------ | ---------------------------------------------------------------- | +| `transition: all` | Specify exact properties: `transition: transform 200ms ease-out` | +| `scale(0)` entry animation | Start from `scale(0.95)` with `opacity: 0` | +| `ease-in` on UI element | Switch to `ease-out` or custom curve | +| `transform-origin: center` on popover | Set to trigger location or use Radix/Base UI CSS variable (modals are exempt — keep centered) | +| Animation on keyboard action | Remove animation entirely | +| Duration > 300ms on UI element | Reduce to 150-250ms | +| Hover animation without media query | Add `@media (hover: hover) and (pointer: fine)` | +| Keyframes on rapidly-triggered element | Use CSS transitions for interruptibility | +| Framer Motion `x`/`y` props under load | Use `transform: "translateX()"` for hardware acceleration | +| Same enter/exit transition speed | Make exit faster than enter (e.g., enter 2s, exit 200ms) | +| Elements all appear at once | Add stagger delay (30-80ms between items) | diff --git a/.agents/skills/impeccable/SKILL.md b/.agents/skills/impeccable/SKILL.md new file mode 100644 index 0000000..2f0241d --- /dev/null +++ b/.agents/skills/impeccable/SKILL.md @@ -0,0 +1,175 @@ +--- +name: impeccable +description: Use when the user wants to design, redesign, shape, critique, audit, polish, clarify, distill, harden, optimize, adapt, animate, colorize, extract, or otherwise improve a frontend interface.

Real working code, committed design choices, exceptional craft. + +## Setup + +You MUST do these steps before proceeding: + +1. Run `node .agents/skills/impeccable/scripts/context.mjs` once per session. If the request names or implies a file, route, or app inside a monorepo, infer the concrete path and run `node .agents/skills/impeccable/scripts/context.mjs --target ` instead. If you've already seen its output in this conversation, do not re-run it. The script either prints the project's PRODUCT.md (and DESIGN.md when present) as a markdown block, or tells you it's missing. Follow whatever it prints. **If it reports `NO_PRODUCT_MD`, stop and follow `reference/init.md` before doing anything else.** If the output ends with an `UPDATE_AVAILABLE` directive, follow it (ask the user once about updating, then continue). It never blocks the current task. +2. If the user invoked a sub-command (`craft`, `shape`, `audit`, `polish`, ...), you MUST read `reference/.md` next. Non-optional. The reference defines the command's flow; without it you will skip steps the user expects. +3. Familiarize yourself with any existing design system, conventions, and components in the code. Read at least one project file (CSS / tokens / theme / a representative component or page). **Required even when you've loaded a sub-command reference in step 2.** Don't reinvent the wheel; use what's there when it works, branch out when the UX wins. +4. Read the matching register reference. **This is non-optional; skipping it produces generic output.** If the project is marketing, a landing page, a campaign, long-form content, or a portfolio (design IS the product), read `reference/brand.md`. If it is app UI, admin, a dashboard, or a tool (design SERVES the product), read `reference/product.md`. Pick by first match: (1) task cue ("landing page" vs "dashboard"); (2) surface in focus (the page, file, or route being worked on); (3) `register` field in PRODUCT.md. +5. **If the project is brand-new (no existing CSS tokens / theme / committed brand colors found in step 3)**, run `node .agents/skills/impeccable/scripts/palette.mjs` to receive a brand seed color and composition guidance. This is the anchor for your primary brand color. Compose the rest of the palette (bg, surface, ink, accent, muted) around it per the script's instructions. Use OKLCH throughout. **Skip this step only if step 3 found committed brand colors in existing tokens; in that case identity-preservation wins.** + +## Design guidance + +Produce ready-to-ship, production-grade code, not prototypes or starting points. Take no shortcuts unless the user asks for them (when in doubt, ask). Don't stop until arriving at a complete implementation (beautiful, responsive, fast, precise, bug-free, on brand). You take attention to detail seriously: every page, section or component crafted is battle tested using the tools available to you (browser screenshotting, computer use, etc). GPT is capable of extraordinary work. Don't hold back. + +### General rules + +#### Color + +- **Verify contrast.** Body text must hit ≥4.5:1 against its background; large text (≥18px or bold ≥14px) needs ≥3:1. Placeholder text needs the same 4.5:1, not the muted-gray default. The most common failure: muted gray body text on a tinted near-white. If the contrast is even close, bump the body color toward the ink end of the ramp; light gray "for elegance" is the single biggest reason AI designs feel hard to read. +- Gray text on a colored background looks washed out. Use a darker shade of the background's own hue, or a transparency of the text color. + +#### Typography + +- Cap body line length at 65–75ch. +- Don't pair fonts that are similar but not identical (two geometric sans-serifs, two humanist sans-serifs). Pair on a contrast axis (serif + sans, geometric + humanist) or use one family in multiple weights. +- Hero / display heading ceiling: clamp() max ≤ 6rem (~96px). Above that the page is shouting, not designing. +- Display heading letter-spacing floor: ≥ -0.04em. Anything tighter and letters touch; cramped, not "designed". +- Use `text-wrap: balance` on h1–h3 for even line lengths; `text-wrap: pretty` on long prose to reduce orphans. + +One hard typographic ceiling you currently miss: +- Display letter-spacing ≥ -0.04em. Your default of -0.05 to -0.085em on display H1s makes the letters touch and reads as cramped. -0.02 to -0.03em is plenty for tight grotesque display; -0.04em is the floor. + +#### Layout + +- Vary spacing for rhythm. +- Cards are the lazy answer. Use them only when they're truly the best affordance. Nested cards are always wrong. +- Flexbox for 1D, Grid for 2D. Don't default to Grid when `flex-wrap` would be simpler. +- For responsive grids without breakpoints: `repeat(auto-fit, minmax(280px, 1fr))`. +- Build a semantic z-index scale (dropdown → sticky → modal-backdrop → modal → toast → tooltip). Never arbitrary values like 999 or 9999. + +#### Motion +- Motion should be intentional, and not be an afterthought. consider it as part of the build. +- Don't animate CSS layout properties unless truly needed. +- Ease out with exponential curves (ease-out-quart / quint / expo). No bounce, no elastic. +- Use libraries for more advanced motion needs (e.g. motion, gsap, anime.js, lenis etc) +- Reduced motion is not optional. Every animation needs a `@media (prefers-reduced-motion: reduce)` alternative: typically a crossfade or instant transition. +- Staggering the items within one list is legitimate. The tell is the uniform reflex (one identical entrance applied to every section), not motion itself; each reveal should fit what it reveals. Suppressing the reflex is never a reason to ship a page with no motion at all. +- Reveal animations must enhance an already-visible default. Don't gate content visibility on a class-triggered transition; transitions pause on hidden tabs and headless renderers, so the reveal never fires and the section ships blank. +- Premium motion materials are not just transform/opacity. Blur, backdrop-filter, clip-path, mask, and shadow/glow are part of the palette when they materially improve the effect and stay smooth. + +#### Interaction + +- Dropdowns rendered with `position: absolute` inside an `overflow: hidden` or `overflow: auto` container will be clipped. Use the native `` / popover API, `position: fixed`, or a portal to escape the stacking context. + +### New projects only (when no prior work exists) + +#### Color & Theme + +- Use OKLCH. +- **The cream / sand / beige body bg is the saturated AI default of 2026.** The whole warm-neutral band (OKLCH L 0.84-0.97, C < 0.06, hue 40-100) reads as cream/sand/paper/parchment regardless of what you call it. Token names like `--paper`, `--cream`, `--sand`, `--bone`, `--flour`, `--linen`, `--parchment`, `--wheat`, `--biscuit`, `--ivory` are tells in themselves. If the brief is "warm, traditional, family-coastal-Italian" or "magazine-warm" or "editorial-restraint", DO NOT translate that into a near-white warm-tinted bg; that's the AI move. Pick: (a) a saturated brand color as the body (terracotta, oxblood, deep ochre, near-black), (b) a true off-white at chroma 0 (or chroma toward the brand's own hue, not toward warmth-by-default), or (c) a darker mid-tone tinted neutral that's clearly the brand's own. "Warmth" in the brand is carried by accent + typography + imagery, not by body bg. +- Tinted neutrals: add 0.005–0.015 chroma toward the brand's hue. Don't default-tint toward warm or cool "because the brand feels that way"; that's the cross-project monoculture move. +- When picking a theme: Dark vs. light is never a default. Not dark "because tools look cool dark." Not light "to be safe.".Before choosing, write one sentence of physical scene: who uses this, where, under what ambient light, in what mood. If the sentence doesn't force the answer, it's not concrete enough. Add detail until it does. +- Pick a **color strategy** before picking colors. Four steps on the commitment axis: + - **Restrained**: tinted neutrals + one accent ≤10%. Product default; brand minimalism. + - **Committed**: one saturated color carries 30–60% of the surface. Brand default for identity-driven pages. + - **Full palette**: 3–4 named roles, each used deliberately. Brand campaigns; product data viz. + - **Drenched**: the surface IS the color. Brand heroes, campaign pages. + +### Absolute bans + +Match-and-refuse. If you're about to write any of these, rewrite the element with different structure. + +- **Side-stripe borders.** `border-left` or `border-right` greater than 1px as a colored accent on cards, list items, callouts, or alerts. Never intentional. Rewrite with full borders, background tints, leading numbers/icons, or nothing. +- **Gradient text.** `background-clip: text` combined with a gradient background. Decorative, never meaningful. Use a single solid color. Emphasis via weight or size. +- **Glassmorphism as default.** Blurs and glass cards used decoratively. Rare and purposeful, or nothing. +- **The hero-metric template.** Big number, small label, supporting stats, gradient accent. SaaS cliché. +- **Identical card grids.** Same-sized cards with icon + heading + text, repeated endlessly. +- **Tiny uppercase tracked eyebrow above every section.** The 2023-era kicker (small all-caps text with wide tracking, "ABOUT" "PROCESS" "PRICING" above each heading) is now the saturated AI scaffold; it appears on 55-95% of generations regardless of brief, which is the definition of a tell. One named kicker as a deliberate brand system is voice; an eyebrow on every section is AI grammar. Choose a different cadence. +- **Numbered section markers as default scaffolding (01 / 02 / 03).** Putting `01 · About / 02 · Process / 03 · Pricing` above every section is the eyebrow trope one tier deeper: reach for it because "landing pages do this" and you're scaffolding by reflex. Numbers earn their place when the section actually IS a sequence (a real 3-step process, an ordered flow, a typed timeline) and the order carries information the reader needs. One deliberate numbered sequence on one page is voice; numbered eyebrows on every section across the site is AI grammar. +- **Text that overflows its container.** Long heading words plus large clamp scales plus narrow grids cause headline overflow on tablet/mobile. Test the heading copy at every breakpoint; if it overflows, reduce the clamp max or rewrite the copy. The viewport is part of the design. + +**Codex-specific defects** (your most-frequent giveaways; refuse-and-rewrite): + +- **`border: 1px solid X` + `box-shadow: 0 Npx Mpx ...` with M ≥ 16px** on the same element. The "ghost-card" pattern: 1px border plus soft wide drop shadow on buttons and cards. Don't pair them. Pick one (a single solid border at the brand color, OR a defined shadow at no more than 8px blur), never both as decoration. +- **`border-radius: 32px+` on cards / sections / inputs.** You over-round. Cards top out at 12–16px; full-pill is fine for tags/buttons. Picking 24/28/32/40px on a card is the codex tell; no brand wants "insanely rounded". +- **Hand-drawn / sketchy SVG illustrations.** Class names like `loose-sketch`, `*-sketch`, `doodle`, `wavy`; `feTurbulence` / `feDisplacementMap` "paper grain" filters; 5-to-30 path crude scenes meant to depict a tangible subject (an otter, a table-and-fork, an album cover). All of these read as amateurish, not whimsical. If you can't render the scene with real assets, ship no illustration. Don't attempt sketchy SVG as a fallback. +- **`repeating-linear-gradient(...)` stripe backgrounds.** Diagonal stripes in `body:before` or section backgrounds are pure codex decoration. Don't. +- **Decorative grid backgrounds.** Two-axis CSS grid overlays built from `linear-gradient(... 1px, transparent 1px)` plus `background-size` are a Codex tell unless the surface is an actual canvas, map, blueprint, or measurement tool. Use product structure, real artifacts, or a plain surface instead. +- **Meta-criticism copy.** Naming a concept then layering an ironic modifier, or staging a strawman to "correct" it. Make the specific claim instead. + +### The AI slop test + +If someone could look at this interface and say "AI made that" without doubt, it's failed. Cross-register failures are the absolute bans above. Register-specific failures live in each reference. + +**Category-reflex check.** Run at two altitudes; the second one catches what the first one misses. + +- **First-order:** if someone could guess the theme + palette from the category alone, it's the first training-data reflex. Rework the scene sentence and color strategy until the answer isn't obvious from the domain. +- **Second-order:** if someone could guess the aesthetic family from category-plus-anti-references ("AI workflow tool that's not SaaS-cream → editorial-typographic", "fintech that's not navy-and-gold → terminal-native dark mode"), it's the trap one tier deeper. The first reflex was avoided; the second wasn't. Rework until both answers are not obvious.

Fold the hits into your picks: many quality / contrast hits → `audit` or `polish`; a specific slop family → the matching command (gradient text or eyebrows → `quieter` / `typeset`, flat or gray palette → `colorize`, and so on).

Preserve perspective only when it belongs to the object or scene itself; if CSS should create the card transform, shadow, rounded clipping, border, or layout, remove that presentation chrome from the raster. + +## Input Contract + +Expect: + +- Approved mock path or screenshot reference. +- Crop paths or a contact sheet with crop ids. +- Output directory. +- Required dimensions, format, transparency needs, and avoid list. +- Notes on what should remain semantic HTML/CSS/SVG instead of raster. + +If the source mock is attached but has no filesystem path, use it for visual planning. Ask for a path only before cropping or writing assets. + +Use defaults unless contradicted: + +- `.webp` for opaque photos, backgrounds, and textures. +- `.png` for transparent cutouts, seals, tickets, and illustrations. +- Target production size or at least 2x display size when dimensions are known. Do not use small full-page mock crop size as the default shipping size. +- Remove UI text, navigation, buttons, labels, and body copy by default. +- Keep physical marks only when the parent says they are part of the asset. +- Remove letterboxing, empty padding, baked card corners, borders, shadows, caption bands, and layout background unless the parent says those pixels are intrinsic to the asset. +- Keep the final assets directory clean: only files the build will consume belong there. Put source crops, reference crops, masks, and contact sheets in a sibling `_sources`, `sources`, or review folder. + +Ask blockers once, globally. Missing source path/crops or output directory blocks production. Exact dimensions, compression targets, retina variants, and format preferences do not block; choose defaults and report them. + +## Workflow + +1. Inventory the full approved mock or every assigned crop. +2. Put each visual role in exactly one bucket: + - `produce`: needs generation, image editing, cleanup, cutout work, or a clean plate before it can ship. + - `direct`: can ship as a crop, format conversion, compression pass, or sourced replacement with no generative cleanup. + - `semantic`: build in HTML/CSS/SVG/canvas, no raster output. +3. Treat full-page mock crops as references, not production-resolution source assets. Put a role in `direct` only when the provided source is already a clean, sufficiently large source asset with no semantic text or presentation chrome. +4. Give the parent an execution order for the `produce` bucket. +5. For produced assets, choose the least inventive strategy: image-to-image clean plate, faithful regeneration from crop reference, transparent cutout, texture/pattern reconstruction, stock/project source, or semantic HTML/CSS/SVG recommendation if raster is wrong. +6. Treat every crop as binding reference. In Codex, use the imagegen skill and built-in `image_gen` path by default when generation or editing is needed. +7. Remove baked-in UI text, navigation, buttons, body copy, and mock chrome unless the text is part of the asset. +8. Think through the final DOM/CSS representation before generating. If CSS will own radius, clipping, shadows, borders, perspective, responsive cropping, captions, or card frames, do not bake those into the bitmap. +9. Save outputs non-destructively in the requested project directory. +10. Compare each output against its source crop. If a review/QA tool is available, run it before the final manifest, then retry each major/fatal finding once before finalizing. + +Use `direct` only for provided source assets that can already ship after crop tightening, conversion, compression, or naming. Do not ship a small crop from the full-page mock as `direct` just because it looks close. + +Use `texture/pattern extraction` only when the source region is already clean enough to sample as texture. If UI, cards, labels, headings, body copy, or footer chrome must be removed to make a reusable texture or background, classify it as crop-derived cleanup or clean-plate work. + +Use `semantic` for dashboards, charts, controls, screenshots of whole UI sections, data widgets, card chrome, app frames, icon toolbars, logos, wordmarks, and anything the final implementation can render crisply in HTML/CSS/SVG/canvas. Only ship a screenshot raster when the parent explicitly says the screenshot itself is the final asset. + +Semantic does not mean ignored. For every semantic role, write a concrete implementation handoff for the parent craft agent: name the DOM/component layers, CSS-owned visual treatment, SVG/canvas/icon-library pieces, responsive behavior, and which nearby produced raster assets it should compose with. For logos and icons, prefer inline SVG/vector or icon-library implementation unless the parent provides a production logo raster. + +For transparency, prefer true alpha output when the tool supports it. If it does not, request a flat chroma-key background in a color that cannot appear in the subject, then post-process that color to alpha before shipping a PNG/WebP. Do not ship the keyed background as the final asset. + +## Prompt Pattern + +Use this shape for image-to-image work: + +```text +Use the provided crop as the approved visual reference. +Recreate the same asset as a clean reusable production image at the target component aspect ratio and at least 2x display resolution. +Preserve silhouette, object/scene perspective, camera angle, palette, lighting, material, texture, and visual role. +Remove baked-in UI copy, navigation, buttons, labels, body text, watermarks, and mock chrome unless explicitly part of the asset. +Remove letterboxing, padding, card borders, rounded clipping, CSS shadows, perspective transforms, caption bands, and layout backgrounds that the implementation should create in code. +Do not add new objects. Do not change the concept. Do not redesign the composition. +``` + +For transparent cutouts, use the imagegen skill's built-in-first chroma-key workflow unless the parent explicitly authorizes a true native transparency fallback. + +## Output Contract + +Return a complete manifest, grouped by `produce`, `direct`, and `semantic`. For each asset include: `id`, `source_crop`, `output_path` when applicable, `strategy`, `prompt_used` when applicable, `dimensions`, `format`, `transparency`, `deviations`, and `qa_status`. + +For each semantic row include `id`, `implementation`, `notes`, and `qa_status`. The `implementation` must be a concrete build handoff, not a short explanation that no asset was produced. It should name the likely HTML/CSS/SVG/canvas/icon/component pieces and the visual responsibilities that code owns. + +`qa_status` must be `accepted`, `needs_parent_review`, or `blocked`. Use `accepted` only after visual comparison passes. Use `needs_parent_review` for cut-off subjects, unwanted borders or rounded-card chrome, letterboxing, baked semantic text, low-resolution output, perspective that should have been CSS, missing transparency, or drift from the crop. Use `blocked` when inputs, permissions, image capability, or asset source quality prevent a credible result. + +End with `execution_order`, `blockers`, and `assumptions` sections. Keep blockers global and minimal. Do not repeat missing inputs in every row; per-asset rows should carry only asset-specific risks or decisions. + +Do not modify implementation code. Do not edit the approved mock. Do not produce final page copy. The parent craft agent owns implementation and final mock fidelity. +''' diff --git a/.agents/skills/impeccable/agents/impeccable_manual_edit_applier.toml b/.agents/skills/impeccable/agents/impeccable_manual_edit_applier.toml new file mode 100644 index 0000000..9ddc6f3 --- /dev/null +++ b/.agents/skills/impeccable/agents/impeccable_manual_edit_applier.toml @@ -0,0 +1,95 @@ +name = "impeccable_manual_edit_applier" +description = "Applies leased Impeccable live manual copy-edit batches to source and returns canonical Apply results." +model_reasoning_effort = "medium" +nickname_candidates = ["Copy Surgeon", "Apply Hand", "Source Scribe"] +developer_instructions = ''' +# Impeccable Manual Edit Applier + +You apply one leased Impeccable live `manual_edit_apply` event to real source files. + +The parent live thread owns polling and protocol replies.

Apply only the entries and ops in the current event. If `chunk` is present, later staged edits arrive in later chunks. +4. Use evidence in order: `sourceHint.file` + `sourceHint.line`, candidate source hints, object-key/text/context matches, then locator or nearby text. +5. For hinted leaf text, replace only exact source text at or near the hint. Do not rewrite parent sections, containers, unrelated markup, or formatting. +6. Never use DOM outerHTML as source text. Source text must be an exact substring already present in the file. +7. For mixed markup that renders one visible phrase, preserve existing child tags and edit only the changed text node. +8. If evidence points to rendered data, edit the source data object or mapped-list item that renders the visible copy. +9. If visible text is also a string literal or object key, update clearly coupled lookup keys for counts, animations, icons, images, assets, styles, metadata, or other dependent maps in the same response. +10. If candidates.objectKeyMatches points at the old visible text as a key, that key must either be renamed to `op.newText` or the entry must fail. Leaving the old key behind can break rendered images, counts, or assets. +11. If one op renames a label and another changes a value looked up by that label, update the same lookup/map entry so the key uses the new label and the value uses the exact new display text. +12. Preserve `op.newText` exactly, including leading zeros, punctuation, casing, spacing, and temporary-looking words. +13. Preserve typed source data. Do not turn numeric, boolean, array, or object model values into strings unless the visible value truly became display text. +14. If numeric copy is rendered from an expression, change the display expression or a clearly coupled lookup value; do not replace the underlying typed model declaration with quoted copy. +15. `sourceContext` is current source after earlier chunks and retries. If event evidence disagrees with current source, current source wins; `sourceEdit.originalText` must appear exactly in the current file. +16. In JSX/TSX, if the original visible copy is rendered by an expression-only text node and the new value is display copy, keep the replacement expression-shaped with a quoted expression such as `{"7 seats"}` rather than raw text. +17. When user copy contains framework-sensitive characters such as `>`, keep the visible text exact but encode it as valid source. In JSX/TSX text nodes, use a quoted expression like `{"alpha -> beta"}` instead of raw text that contains `>`. +18. If numeric-looking visible text is not a valid safe numeric literal for the source language, write it as display text. Leading-zero decimals and mixed alphanumeric counts must be quoted/escaped as strings in JS/TS data. +19. If numeric source data is changed to non-numeric visible text, write the new visible text as a quoted source string. Never substitute a similar number or a bare identifier. +20. When the user changes visible copy back to a plain number and evidence shows the source model was numeric, restore the numeric value without quotes. +21. If a dependency is ambiguous or broad, fail that entry and leave no partial edits for it. +22.

+``` + +**Each variant div contains exactly one top-level element: the full replacement for the original.** Use the same tag as the original (e.g. `
` if the user picked a `
`). Loose siblings (heading + paragraph + div as direct children of the variant div) break the outline tracking and the accept flow, which both assume one child. + +The first variant has no `display: none` (visible by default). All others do. If variants use only inline styles and no preview CSS, omit the ` +
+ {/* variant 1 */} +
+

+``` + +The wrap script already gives you a single-rooted JSX wrapper: a `
` outer element with the marker comments tucked inside. Drop the variants block above into the "Variants: insert below this line" comment and the source stays valid TSX. + +### 7. Parameters (composition-sized, 0–4 per variant) + +Each variant can expose **coarse** knobs alongside the full HTML/CSS replacement. The browser docks a small panel to the right of the outline with one control per parameter. The user drags/clicks and sees instant feedback: there is zero regeneration cost because the knob toggles a CSS variable or data attribute that the variant's scoped CSS is already authored against. + +**What “optional” does not mean.** Parameters are not nice-to-have decoration on large work. The word meant “omit controls that are redundant or cosmetic,” not “default to zero because three variants were enough work.” + +**When to add.** As soon as the variant’s scoped CSS has a meaningful continuous or stepped axis: density, color amount, type scale, motion intensity, column weight, and so on. If you can imagine the user muttering “a bit tighter” or “a touch more accent” **without** wanting a full regeneration, wire that axis. **Not** micro-margins or one-off nudges; those are not parameters. + +**Freeform (`action` is `impeccable`) bias.** You did not load a sub-command reference, so you must **choose** signature axes yourself. Match the budget table: for a hero or large composition, that means **2–3 axes per variant**, not 1. Prefer knobs that sit on the dimensions where your three variants actually differ (if density varies, expose it as a `steps` knob; if color commitment varies, expose it as a `range`). A hero that ships with **0** params is almost always a mistake, not a judgment call. A hero with exactly **1** param is underweight unless the design is genuinely a fixed-point comparison. Start from the budget table, not from zero. + +**Budget scales with the element's visual weight, not token budget.** Knobs need real estate to read as tunable; three sliders on a single control are noise. + +- **Leaf / tiny**: a single button, icon, input, bare heading, solitary paragraph: **0 params.** +- **Small composition**: labeled input, simple card, short callout (≤ ~5 visual children): **0–1** params when one dominant axis is obvious; otherwise **0.** +- **Medium composition**: section component, nav cluster, dense card, short feature block (6–15 visual children): **target 2**; **1** is acceptable if the block is simple; **0** only when variants are truly fixed points. +- **Large composition**: hero section, full page region, spread layout, strong internal structure (16+ visual children or multiple sub-sections): **target 2–3**; **up to 4** when several independent axes (e.g. structure `steps` + `density` + one accent) are all authored in scoped CSS. + +**When in doubt, ask whether a dial exists before defaulting to zero.** The user can always request more variants, but the point of live mode is instant tuning without another Go. Crowding the panel is bad; **under-shipping** knobs on a dense composition is the more common failure for freeform. Count by **visual** children, not DOM depth; a shallow-but-wide hero is still large. + +**Hard cap per variant**: at most **four** parameters so the panel stays legible; rare fifth only if the reference explicitly allows it. + +**How to declare.** Put a JSON manifest on the variant wrapper (HTML/JSX path). **On the Svelte `svelte-component` path, do not use this attribute** (Svelte can't compile `{` inside an attribute value). Declare params in `componentDir/params.json` keyed by variant number instead (see the Svelte component paragraph in the wrap section). The param schema below is identical for both paths. + +```html +
+ ...variant content... +
+``` + +**Three kinds:** + +- `range`: smooth slider. Drives a CSS custom property `--p-` on the variant wrapper. Author CSS with `var(--p-color-amount, 0.5)`. Fields: `min`, `max`, `step`, `default` (number), `label`. +- `steps`: segmented radio. Drives a data attribute `data-p-` on the variant wrapper. Author CSS with `:scope[data-p-density="airy"] .grid { ... }`. Fields: `options` (array of `{value, label}`), `default` (string), `label`. +- `toggle`: on/off switch. Drives BOTH a CSS var (`--p-: 0|1`) and a data attribute (present when on, absent when off). Use whichever is more convenient. Fields: `default` (boolean), `label`. + +**Signature params per action.** For named sub-commands, read that action’s `reference/.md` for one or two **MUST** params (e.g. `layout` → `density`). Those are non-negotiable when the design can express them. **Freeform has no file-level MUST**; the **Freeform (`impeccable`) bias** in this section is the stand-in. If the user’s action is both stylized and sub-command (e.g. `colorize`), the sub-command’s MUST list takes precedence for its axes; still respect the **Hard cap** and add no redundant duplicate knobs. + +**Reset on variant switch.** User dials density on v1, flips to v2, v2 starts at v2's declared defaults. Known limitation; preservation across variants may land later. + +**On accept**, the browser sends the user's current values in the accept event. `live-accept.mjs` writes them as a sibling comment: + +```html + +``` + +The carbonize cleanup step (see below) reads that comment and bakes the chosen values into the final CSS. For `steps`/`toggle` attribute selectors: keep only the branch matching the chosen value, drop the others, collapse `:scope[data-p-density="packed"] .grid` to a semantic class rule. For `range` vars: either substitute the literal or keep the var with the chosen value as its new default. + +### 8. Signal done + +```bash +node .agents/skills/impeccable/scripts/live-poll.mjs --reply EVENT_ID done --file RELATIVE_PATH +``` + +`RELATIVE_PATH` is relative to project root (`public/index.html`, `src/App.tsx`, etc.); the browser fetches source directly if the dev server lacks HMR. + +Then run `live-poll.mjs` again immediately. + +### Aborting an in-flight session + +If wrap or generation fails after the browser has flipped to GENERATING (e.g. wrap landed on the wrong source branch and you've already reverted it, or generation hit an unrecoverable error), tell the **browser** so its bar resets to PICKING: + +```bash +node .agents/skills/impeccable/scripts/live-poll.mjs --reply EVENT_ID error "Short reason" +``` + +Don't run `live-accept --discard` for this; that's a pure file mutator, the browser doesn't see it, and the bar gets stuck on the GENERATING dots forever (the user has to refresh). `--discard` is only correct when the **browser** initiated the discard (user clicked ✕ during CYCLING) and the agent is just running source-side cleanup the browser already triggered. + +## Handle fallback + +When wrap returns `fallback: "agent-driven"`, the deterministic flow doesn't apply. Pick up here. + +The goal is the same: give the user three variants to choose from AND persist the accepted one in a place the next build won't wipe. The difference is that you have to pick the right source file yourself. + +### Step 1: Identify where the element actually lives + +Use the error payload: + +- `element_not_in_source` with `generatedMatch: "public/docs/foo.html"`: the served HTML is generated. Find the generator (grep for writers of that path, e.g. `scripts/build-sub-pages.js`, an Astro/Next template) and locate the template or partial that emits this element. +- `element_not_found`: the element is runtime-injected. Look for the component that renders it (React/Vue/Svelte), the JS that assembles it, or the data source that feeds it. +- `file_is_generated` with `file: "..."`: user pointed at a generated file explicitly. Same resolution as `element_not_in_source`. + +Read the candidate source until you're confident where a change to the element would belong. If the change is purely visual, that source might be a shared stylesheet, not the template. + +### Step 2: Show three variants in the DOM for preview + +The browser bar is waiting for variants. Even without a wrapper in source, you still need to show something: + +1. Manually write the wrapper scaffold into the **served** file (the one the browser actually loaded). Use the same structure `live-wrap.mjs` produces; `

`. +2. Insert your three variant divs inside it, same shape as the deterministic path. +3. Signal done with `--reply EVENT_ID done --file `. The browser's no-HMR fallback will fetch and inject. + +This served-file edit is **temporary**: next regen wipes it, and that's fine. The real work happens on accept. + +### Step 3: On accept, write to true source + +When the accept event arrives (`_acceptResult.handled` will usually be `false` here because accept also refuses to persist into generated files; see Handle accept for the carbonize branch), extract the accepted variant's content and write it into the source you identified in Step 1: + +- Structural change → edit the template / component source. +- Visual-only change → add or update rules in the appropriate stylesheet; remove the inline `' : '')); + if (paramValues && Object.keys(paramValues).length > 0) { + lines.push( + bodyIndent + commentSyntax.open + ' impeccable-param-values ' + id + ': ' + JSON.stringify(paramValues) + ' ' + commentSyntax.close, + ); + } + lines.push(bodyIndent + commentSyntax.open + ' impeccable-carbonize-end ' + id + ' ' + commentSyntax.close); + lines.push(bodyIndent + '
