## Install

```sh
agentstack add skill-mariusyvard-nulltohero-siteasy
```

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

Designs and iterates production-grade frontend interfaces. Real working code, committed design choices, exceptional craft. Accessible to beginners, powerful enough for experts.

Good taste is trained, not innate — the ability to see beyond the obvious and recognize what elevates. Unseen details compound: when a feature works exactly as assumed, users proceed without a second thought. That is the goal.

## Setup (non-optional)

> Several commands (`audit`, `craft`, quality passes) call the `impeccable` CLI via `npx`. Tested with impeccable 2.3.2; pin with `npx impeccable@2.3.2` to avoid upstream drift.

Before any design work or file edits, pass these gates. Skipping them produces generic output that ignores the project.

| Gate | Required check | If fail |
|---|---|---|
| Context | PRODUCT.md and DESIGN.md are read from the workspace. | Use Read to look for PRODUCT.md; if missing, run `/siteasy setup` first. |
| Product | PRODUCT.md exists and is not empty or placeholder (`[TODO]` markers,  1px as a colored accent on cards, list items, callouts.
- **Gradient text.** `background-clip: text` on anything other than display-only hero type.
- **Glassmorphism as default.** Blurs and glass cards used decoratively.
- **The hero-metric template.** Big number, small label, supporting stats, gradient accent.
- **Identical card grids.** Same-sized cards with icon + heading + text, repeated endlessly.
- **Centered hero, centered text, dark image.** Use an asymmetric split instead.
- **Modal as first thought.** Exhaust inline / progressive alternatives first.
- **Inter on brand surfaces** (and other training-data defaults like Outfit and DM Sans; see references/brand.md). Use Geist, Cabinet Grotesk, or Satoshi. Product UI may use system stacks (see references/product.md).
- **Serif fonts in software UIs or dashboards.**
- **AI Purple/Blue gradient aesthetic.** Use neutral bases (Zinc/Slate) with singular, concrete accents.
- **Pure black (#000) for large areas.** Use off-black with a hint of hue (chroma 0.005+).
- **`transition: all`.** Always specify exact properties.
- **`ease-in` on UI animations.** Use `ease-out` or a custom curve.
- **Durations > 300ms on UI feedback.**
- **Generic placeholder content.** "John Doe", "Acme Corp", "99.99%". Use realistic names, organic numbers (`47.2%`), and `picsum.photos/seed/{word}/width/height`.
- **Emojis in the website you build** (code, markup, or UI copy). Replace with proper icons (Radix, Phosphor) or SVG primitives. (Status markers like PASS/WARN/FAIL in audit reports are exempt.)

### Copy

- Every word earns its place. No restated headings, no intros that repeat the title.
- **No em dashes.** Use commas, colons, semicolons, or parentheses.
