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:

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

For full tool details, read 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:

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 an
