What this skill does

# Refero Design

Refero gives agents taste and product evidence. Use it before design work instead of
relying on generic model knowledge.

Refero has three research layers:

1. **Styles** - visual direction and taste.
2. **Screens** - concrete UI patterns and product-screen decisions.
3. **Flows** - multi-step journey logic.

Best results come from combining layers: visual direction from styles, concrete UI
patterns from screens, and sequencing from flows when the task has multiple steps.

## Non-Negotiables

- **Research before design work.** Every design must be grounded in references before
  implementation. Do not rely on the model's generic design taste.
- **Use styles first for visual work when Refero MCP tools are available.** If tools are
  unavailable, use bundled craft references and keep the same reference-lock workflow.
- **Do not copy one reference.** Study several strong references and synthesize a new
  direction for the user's product.
- **Do not average references into a safe middle.** When references conflict, choose one
  dominant direction and preserve its sharp traits. Secondary references may add narrow
  details only.
- **Do not change token meanings.** If a reference says a color, font, radius, shadow,
  gradient, or component is for a specific role, use it only for that role or omit it.
- **Respect imagery guidance.** If a style depends on photography, illustration, product
  shots, or graphics, preserve the media role. Use real/generated/stock assets when
  available; otherwise create an intentional placeholder with art direction. Do not fake
  complex imagery with weak CSS, text, or decorative boxes.
- **Do not use generic frontend/product design skills as a parallel design authority**
  when this skill is available. Refero is the design methodology; generic design skills
  tend to pull work back toward generic AI design.
- **Research output must be specific.** Name the references, describe concrete choices,
  and explain what will be adapted.
- **No design from vibe memory.** Every major visual, layout, content, or interaction
  decision must trace to Refero research, the user's brief, or a craft reference.
- **Synthesize before implementation.** Turn research into a concept, token direction,
  and concrete decision ledger before drawing or coding.

## MCP Setup

This skill is useful on its own as a research-first design methodology and craft reference.
Research is mandatory. Use Refero MCP for live style, screen, and flow research when
available; otherwise research with bundled craft references and any user-provided references.

Typical MCP setup:

```bash
claude mcp add --transport http refero https://api.refero.design/mcp --header "Authorization: Bearer <token>"
```

For full tool details, read [references/mcp-tools.md](references/mcp-tools.md).

## Discovery

Before researching, form a short design brief. Ask only for missing information that
would materially change the result; otherwise make reasonable assumptions and proceed.

Clarify:

- what is being designed
- platform: web, iOS, or both
- audience and technical level
- primary user goal
- desired feeling or brand direction
- business/user objections to overcome
- constraints: existing brand, framework, deadline, accessibility, content
- whether the task needs visual direction, concrete UI patterns, journey logic, or a mix

Brief format:

```text
Designing [WHAT] for [WHO] on [PLATFORM].
Goal: [PRIMARY USER GOAL].
Tone: [DESIRED FEELING].
Main objection/risk: [OBJECTION].
Must remember: [HOOK OR DISTINCTIVE IDEA].
Constraints: [CONSTRAINTS].
Research needed: [styles/screens/flows].
```

## Tool Routing

### Use Styles First For Visual Work

Use `refero_search_styles` when the user asks to design, redesign, improve, polish, or
create anything with a visual component.

A style is a semantic design reference extracted from a real web marketing/product page.
It is not a screenshot and not a component library. Search results give previews; full
style references from `refero_get_style` provide design guidance such as visual thesis,
tokens, typography, layout/composition, section rhythm, spacing, elevation, surfaces,
components, imagery treatment, implementation notes, and do/don't rules.

Current limitation: Refero styles currently cover web marketing/product pages such as
landing pages, pricing pages, product marketing sites, editorial brand sites, and SaaS
websites. They do not currently cover in-app dashboards, auth screens, settings screens,
or iOS app screens as style systems. Still use styles for product UI tasks to establish
visual language, then use screens/flows for product logic.

Use styles for:

- look and feel
- brand direction
- landing pages and marketing pages
- typography, palette, layout, section structure, spacing, radius, elevation, surfaces
- component treatments and sometimes component/code examples
- imagery and product screenshot treatment
- design-system inspiration
- making a generic interface feel more tasteful

### Use Screens For Concrete UI Patterns

Use `refero_search_screens` when you need:

- a specific screen type
- a specific component or UI pattern
- page layout and content hierarchy
- copy and CTA patterns
- form/state examples
- dashboards, settings, modals, tables, pricing, empty states, auth, or product-screen details

After finding strong screens:

- use `refero_get_screen` for full details
- use `refero_get_similar_screens` to expand from a strong example
- use `refero_get_screen_image` only when raw screenshot inspection is needed

### Use Flows For Journeys

Use `refero_search_flows` when the task has a before/after sequence:

- onboarding
- signup
- checkout
- subscription management
- cancellation
- account deletion
- password reset
- profile/settings changes
- any multi-step process

After finding a strong flow, use `refero_get_flow` for step-by-step goals, actions,
system responses, and completion states.

## Research Workflow

### 1. Research Visual Direction With Styles

For any visual design task, start here.

Recommended loop:

1. Search 3-5 different visual angles.
2. Include one broad aesthetic query.
3. Include one domain/category query.
4. Include one known-brand or strong-product query when relevant.
5. Retrieve 3-4 strong styles with `refero_get_style`; full styles are large, so split larger research into multiple batches.
6. Compare what each style contributes.
7. Choose one primary foundation and borrow 1-2 specific details from other styles.
8. Lock the primary reference's signature traits before implementation.

Good style queries:

- editorial monochrome SaaS landing page
- warm trustworthy healthcare product marketing
- premium fintech website with restrained typography
- playful creator tool landing page with vivid accents
- developer tool website with product screenshots
- luxury ecommerce editorial product page
- productivity SaaS with airy spacing
- data infrastructure website dark technical style
- Attio editorial SaaS typography
- Linear changelog dark developer tool
- shadcn monochrome design system

Extract from styles:

- north star / visual thesis
- typography personality and type scale
- color roles and accent discipline
- spacing density and rhythm
- layout system, section rhythm, and composition patterns
- card/button/surface treatments
- borders, shadows, radius
- elevation and depth rules
- component examples and implementation/code notes when present
- imagery, graphics, illustration, or product screenshot treatment
- media asset strategy: real asset, generated/stock asset, code-native primitive, product screenshot, or placeholder
- do/don't rules
- one memorable visual move to adapt

Synthesis rule:

- Primary style: overall mood, density, and structure.
- Secondary styles: specific borrowed details.
- User context: adapt everything to the product, audience, and task.
- Do not use the average/intersection of all references. If one reference is dark, one is
  acid, and one is serif, the a
