Builds and refines shippable frontend interfaces for ibl.ai apps: real working code, decisive design calls, and craft that holds up under inspection.

[BRAND.md](https://raw.githubusercontent.com/iblai/vibe/refs/heads/main/BRAND.md)
is the **default** design system (colors, typography, spacing, radius, shadows,
component style). When the project already carries its own design system
(a v0 export, a custom theme, a partner-branded shell, a `DESIGN.md`/`PRODUCT.md`),
**defer to that instead**. See [ibl.ai design defaults](#iblai-vibe-design-defaults-brandmd-fallback) below.

## Setup

> **Project-scoped skill.** Scripts are invoked by the relative path
> `node .claude/skills/iblai-vibe-design/scripts/<x>.mjs`, resolved against the
> project root (cwd). The skill must live at
> `<project>/.claude/skills/iblai-vibe-design/` (the `skills/` → `.claude/skills/`
> symlink that vibe sets up at install). A user-global
> (`~/.claude/skills/`) or plugin install will not resolve these paths —
> install per-project. Script state (`.impeccable/`, `live/`, `critique/`)
> is also written under the project root by design.

Run all three before touching design work or editing files:

1. Pull project context (PRODUCT.md / DESIGN.md) with the loader script.
2. Determine the register, then open its matching reference (brand.md or product.md).
3. **When the user invoked a sub-command (`craft`, `shape`, `audit`, ...), open that command's reference file as well.** Not optional: running `craft` without `craft.md` loaded drops the shape-and-confirm step the user is counting on.

Skip any of these and the result turns generic, blind to the project.

### 1. Context gathering

Two files, matched case-insensitively. By default the loader reads the project root, then falls back to `.agents/context/` and `docs/` when the root has neither. Point it elsewhere with `IMPECCABLE_CONTEXT_DIR=path/to/dir` (absolute, or relative to cwd).

- **PRODUCT.md**: required. Audience, brand, tone, anti-references, strategic principles.
- **DESIGN.md**: optional but strongly recommended. Color, typography, elevation, components.

Fetch both in a single call:

```bash
node .claude/skills/iblai-vibe-design/scripts/load-context.mjs
```

Read the whole JSON payload. Don't route it through `head`, `tail`, `grep`, or `jq`. Its `contextDir` field reports where the files resolved from.

Already have this output earlier in the session? Don't re-run it. Reload only after `/iblai-vibe-design teach` or `/iblai-vibe-design document` (both rewrite the files), or after the user hand-edits one.

`/iblai-vibe-design live` already warms context through `live.mjs`; once `live.mjs` has run, skip `load-context.mjs` for the rest of the session.

When PRODUCT.md is absent, empty, or still a placeholder (`[TODO]` markers, under 200 chars): run `/iblai-vibe-design teach` first, then pick the user's original task back up with the fresh context. If that task was `/iblai-vibe-design craft`, re-enter through `/iblai-vibe-design shape` before any implementation work.

If DESIGN.md is missing, don't nudge and then work blind. Resolve a design
system in this order (first match wins), nudge once per session
(*"Run `/iblai-vibe-design document` for a project-specific DESIGN.md"*), then proceed:

1. The project's own tokens (see detection table below).
2. The ibl.ai **BRAND.md** defaults.

### ibl.ai design defaults (BRAND.md fallback)

With no DESIGN.md present, first check whether the project already defines
its own visual language. **If it does, the project's tokens win** — never
paper over them with ibl.ai brand defaults.

| Signal | Where to look | What it means |
|--------|---------------|----------------|
| `components.json` with shadcn entries | repo root | shadcn/ui (often v0). Match its `style`, `baseColor`, `cssVariables`. |
| `components/ui/` populated | `components/ui/*.tsx` | shadcn primitives installed. Reuse them; don't add a parallel UI lib. |
| Custom CSS vars beyond shadcn defaults | `app/globals.css`, `styles/globals.css` | `--primary`, `--brand-*`, custom radius/shadow tokens define the palette. Bind to these, not ibl.ai hex. |
| `tailwind.config.*` extends colors/fonts | repo root | `theme.extend.colors/fontFamily` carry intent. Match them. |
| Tailwind v4 `@theme { }` block | `globals.css` | Same as above for Tailwind v4. |
| Custom font via `next/font` | `app/layout.tsx` | Don't replace it. Inherit it. |
| Existing app shell | `components/{navbar,sidebar,header,app-shell}.tsx` | Plug into it; don't add a second shell. |
| `BRAND.md` / `DESIGN.md` / `design-tokens.*` | repo root, `docs/`, `lib/` | The project documents its own language. Read it first. |

**If none of those signals are present**, the project has no design
system — adopt the ibl.ai
[BRAND.md](https://raw.githubusercontent.com/iblai/vibe/refs/heads/main/BRAND.md)
as the DESIGN.md for this session: its color palette (primary `#0058cc`,
brand gradient `linear-gradient(135deg, #00b0ef, #0058cc)`), Open Sans
(semibold rendered one step lighter), spacing/radius/shadow scales, shadcn
`base-nova` + `neutral` + Lucide component style, and the Apple-inspired
layout language. Give BRAND.md tokens the same authority a DESIGN.md would
carry — the shared design laws below still stack on top.

State what you resolved in one line before designing:

> Using ibl.ai BRAND.md defaults (no project design system detected).

or

> Detected shadcn-new-york + custom `--primary`. Binding to project tokens, not ibl.ai defaults.

An app on `@iblai/iblai-js` (the dependency, or an `iblai.env`) is an ibl.ai
app: BRAND.md *is* its design system, and diverging from it — font, scale,
accent colour, SDK internals, shell, spinner, dark mode — is a question for
the user, never a decision. `/iblai-vibe-component` (House components) has
the components and the probe; BRAND.md the wiring and the scale.

### 2. Register

Each design task is one of two: **brand** (marketing, landing, campaign, long-form content, portfolio: the design IS the product) or **product** (app UI, admin, dashboard, tool: the design SERVES the product).

Settle this before designing. Precedence: (1) a cue in the task wording ("landing page" vs "dashboard"); (2) the surface in focus (the page, file, or route under work); (3) the `register` field in PRODUCT.md. First match wins.

When PRODUCT.md carries no `register` field (older files), infer it once from its "Users" and "Product Purpose" sections and cache that value for the session. Recommend `/iblai-vibe-design teach` so the field gets recorded explicitly.

Open the matching reference: [reference/brand.md](https://github.com/iblai/vibe/blob/main/skills/ship/iblai-vibe-design/reference/brand.md) or [reference/product.md](https://github.com/iblai/vibe/blob/main/skills/ship/iblai-vibe-design/reference/product.md). The shared design laws below hold for both.

## Shared design laws

These hold for every design, in both registers. Let implementation effort track the aesthetic: maximalism wants elaborate code, minimalism wants precision. Interpret with intent. Diverge between projects; never keep landing on the same choices. Claude is capable of extraordinary work here. Don't hold back.

### Color

- Work in OKLCH. Pull chroma down as lightness approaches 0 or 100; high chroma at the extremes reads garish.
- Never `#000` or `#fff`. Bias every neutral toward the brand hue (chroma 0.005–0.01 is plenty).
- Choose a **color strategy** before choosing colors. Four points on the commitment axis:
  - **Restrained**: tinted neutrals + one accent ≤10%. Product default; brand minimalism.
  - **Committed**: one saturated color owns 30–60% of the surface. Brand default for identity-led pages.
  - **Full palette**: 3–4 named roles, each placed on purpose. Brand campaigns; product data viz.
  - **Drenched**: the surface IS the color. Brand heroes and campaign pages.
- The "one accent ≤10%" cap is Restrained only. Committed / Full palette / Drenched blow past it on purpose. Don't reflexively flatten every design back to Restrained.

### Theme

Dark vs. light is never automatic. Not dark "because tools look cool dark." Not light "to play it safe."

Before deciding, 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 isn't concrete enough; add detail until it does.

"Observability dashboard" forces nothing. "SRE glancing at incident severity on a 27-inch monitor at 2am in a dim room" forces it. Reason from the sentence, not the category.

### Typography

- Keep body measure at 65–75ch.
- Build hierarchy from scale + weight contrast (≥1.25 ratio between steps). No flat scales.

### Layout

- Vary spacing for rhythm. Identical padding everywhere is monotony.
- Cards are the lazy default. Use them only when they're genuinely the best affordance. Nested cards are always wrong.
- Don't box everything in a container. Most things don't need one.

### Motion

- Never animate CSS layout properties.
- Ease out on exponential curves (ease-out-quart / quint / expo). No bounce, no elastic.

### Absolute bans

Match and refuse. About to write any of these? Rebuild the element with a different structure.

- **Side-stripe borders.** A `border-left` or `border-right` over 1px used as a colored accent on cards, list items, callouts, or alerts. Never deliberate. Replace with full borders, background tints, leading numbers/icons, or nothing.
- **Gradient text.** `background-clip: text` over a gradient background. Decoration, never signal. Use one solid color. Carry emphasis with weight or size.
- **Glassmorphism as default.** Decorative blur and glass cards. Rare and deliberate, or absent.
- **The hero-metric template.** Huge number, tiny label, supporting stats, gradient accent. The SaaS cliché.
- **Identical card grids.** Equal-size cards of icon + heading + text, repeated without end.
- **Modal as first thought.** A modal is usually the lazy route. Exhaust inline / progressive options first.

### Copy

- Every word pays rent. No restated headings, no intro that echoes the title.
- **No em dashes.** Use commas, colons, semicolons, periods, or parentheses. The `--` substitute is out too.

### The AI slop test

If a viewer could glance at the interface and say "AI made that" with no doubt, it failed. Cross-register tells are the absolute bans above. Register-specific tells live in each reference.

**Category-reflex check.** Run it at two altitudes; the second catches what the first misses.

- **First-order:** if the theme + palette are guessable from the category alone ("observability → dark blue", "healthcare → white + teal", "finance → navy + gold", "crypto → neon on black"), that's the first training-data reflex. Rework the scene sentence and color strategy until the domain no longer gives the answer away.
- **Second-order:** if the aesthetic family is guessable 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"), that's the trap one tier down: the first reflex was dodged, the second wasn't. Rework until neither answer is obvious. The brand register's [reflex-reject aesthetic lanes](https://github.com/iblai/vibe/blob/main/skills/ship/iblai-vibe-design/reference/brand.md) list catches the currently-saturated families.

Two management commands round it out: `pin <command>` and `unpin <command>`, covered below.

### Routing rules

1. **No argument**: present the table above as the command menu, grouped by category, and ask what they'd like to do.
2. **First word matches a command**: open its reference file and follow it. Everything after the command name is the target.
3. **First word matches nothing**: treat it as a general design request. Apply setup, the shared design laws, and the loaded register reference, with the full argument as context.

Setup (context gathering, register) is already done by this point; sub-commands don't re-invoke `/iblai-vibe-design`.

When the first word is `craft`, setup still runs first, but [reference/craft.md](https://github.com/iblai/vibe/blob/main/skills/ship/iblai-vibe-design/reference/craft.md) drives the rest of the flow. If setup triggers `teach` as a blocker, finish teach, refresh context, then resume the original command and target.

## Pin / Unpin

**Pin** registers a standalone shortcut so `/<command>` runs `/iblai-vibe-design <command>` directly. **Unpin** removes it. The script writes into every harness directory present in the project.

```bash
node .claude/skills/iblai-vibe-design/scripts/pin.mjs <pin|unpin> <command>
```

`<command>` is any entry from the table above. Report the script's result tersely: confirm the new shortcut on success, relay stderr verbatim on error.
