Art & Design

Generate design tokens, create color palettes, calculate typography scales, build component systems, and prepare developer handoff documentation.

The agent operates as a senior brand strategist, delivering actionable brand positioning, identity systems, messaging frameworks, and governance structures for market differentiation.

Prevent and remove redundant UI copy and explanatory components. Use when creating or reviewing screens, forms, empty states, subtitles, helper text, banners, badges, or cards that repeat what the interface already communicates. Keep necessary labels, constraints, risks, permissions, and unknown states. Not a general visual redesign.

Use when the user asks to "pre-launch check the landing page", "run a Quality-Score preflight", or "verify ad-to-page message match before launch"; produces an ad↔page continuity report — message-match gaps, above-the-fold check, page-speed read, form-friction count, mobile-render flags — as a pass/fix punch list. Not for redesigning or rewriting the page — use landing-optimizer; not for scoring the account or the RQS — use ad-account-auditor. 落地页体验预检/广告落地页一致性检查

Build a readable diagram by choosing its behavioral meaning before its visual form, preserving source relationships, and checking the rendered artifact for fidelity and accessibility.

设计或修改程序的交互（按钮位置、功能入口、操作流程、表单、对话框、菜单、设置页、CLI 参数与提示）时，从第一次使用的用户角度走一遍主要任务：按钮放在用户视线和操作对象旁边，常用功能一步可达，删掉多余的确认、模式切换、向导步骤和重复输入，不加用户没要的功能、菜单、设置项和占位入口，给好默认值、即时反馈和能看懂的出错提示，遵循平台惯例。在写或改 UI、加新功能入口、设计多步流程、写表单和弹窗、或用户反映"不好用 / 找不到 / 太麻烦"时使用，交付前要实际走一遍并数步数。Use whenever you design or change how a user interacts with a program, and before declaring UI work done.

写 UI（网页、桌面程序、Electron、移动端、HTML 报告、仪表盘、组件）之前，先判断使用场景再定视觉风格：商务、生产力、内部工具、数据后台、开发者工具要克制、清晰、信息密度高；娱乐、游戏、创意、社交、个人兴趣类可以大胆用配色、插画、动效、特色字体。避免 AI 惯性风格：毛玻璃（glassmorphism）、新拟态（neumorphism）、紫蓝渐变、霓虹发光、渐变光斑背景、到处都是大圆角卡片和 emoji 图标，让严肃工具看起来像游戏；也避免把好玩的东西做成灰扑扑的后台。项目已有设计系统时照着用；场景不明确时，先给出两三个具体方向问用户。Use before designing or styling any UI, and whenever choosing colors, fonts, effects or layout density.

Use whenever you build or restyle a page, component, animation or 3D scene: direction, tokens, motion, QA.

Audit any public website for speed, SEO, accessibility and best practices with Google PageSpeed Insights through Developh's free MCP server, then turn the result into a short, ranked fix list. Load when someone asks why a website is slow, to check a site's speed, Core Web Vitals or SEO, to audit or compare websites, or in Portuguese: «porque é que o meu website está lento?», «auditoria ao meu website».

Use when creating, redesigning, formatting, or reviewing a resume, CV, 이력서, or 경력기술서 layout, typography, tables, anti-patterns, page breaks, employer-provided form, or final DOCX/PDF. Applies to Korean-English documents and experienced candidates across job functions. Content strategy belongs to a resume-writing skill.

Craft-first interface design for dashboards, admin panels, SaaS apps, tools, settings pages, data interfaces, and interactive products. Use when designing, building, reviewing, auditing, or refining product UI where visual craft, layout hierarchy, tokens, states, visual direction, or design-system consistency matter. Not for marketing pages, landing pages, campaigns, or brand-only work.

Use whenever a new UI needs a look: six style directions, the pick saved as DESIGN.md.

Design, improve, clean up, or implement polished production interfaces with coherent component selection, accessibility, responsive behavior, maintainable design tokens, restrained motion, and complete UI states. Use for dashboards, SaaS products, browser extensions, AI tools, admin panels, settings, forms, tables, marketing pages, component libraries, UI audits, and frontend rebuilds where Codex must select the smallest appropriate UI stack and deliver working code.

Design system for Ratatui terminal UIs - theme tokens, background integrity, layout and hit-testing, glyph fallbacks and deterministic screenshot gates. Use when building a new Ratatui dashboard or redesigning an existing TUI's visuals.

Use when designing operational dashboards.

Find the look of a new product, choose between design directions, or make on-brand variants to pick from. Builds up to four whole, working one-page HTML directions from one shared brief with hard rules, captures each at desktop and phone in light and dark, and writes a comparison page with a recommendation. After the person picks, builds structure-only variants on the locked look, each round ending with numbered questions, then locks the chosen tokens into a brand file the build brief and...

Design, implement, modify, review, or optimize product task experiences for desktop, mobile, and web, or advise on UX principles. Use for information organization, interaction behavior, navigation, feedback, user control, recovery, interface wording, and accessible operation. Combine with UI guidance when the task also changes visual presentation.

Design, implement, modify, review, or optimize visual interfaces for desktop, mobile, and web, or advise on UI principles. Use for visual hierarchy, typography, color, layout, responsive presentation, control geometry, and motion. Combine with UX guidance when the task also changes information organization or interaction behavior.

Generates publication-grade editorial architecture, system flow, data pipeline, and sequence diagrams as standalone HTML files with inline SVG and CSS.

Turns sources for a song (tab screenshots, PDFs, links, notes) into one compact bass tab in a fixed format, and renders it to a one-or-two-page play-along chart PDF with section labels, collapsed repeats, chords and lyrics. Use when asked to make, fix, render or print a bass tab.

Act as a UI/UX designer and frontend engineer to create, adopt, extend and update a project-specific design system. Clarifies the product, explores visual directions, freezes design tokens, builds shared components with Storybook, and builds pages by page type (landing page, blog, dashboard). Produces PRODUCT.md, DESIGN.md, a design tokens file, shared components and a check script. Use when starting a new frontend or UI project, setting up or adopting a design system, defining design...

Design, generate, automatically route, validate, and export manufacturable KiCad 9 printed circuit boards from a design spec, netlist, schematic, or existing board. Use when creating or editing PCB layouts, placing real library footprints, routing with Freerouting, defining stackups and nets, running KiCad DRC/DFM, or producing Gerbers and a professional release report. Covers automatic design, controlled-impedance/RF/flex/high-voltage gates, and structural validation.

Review UI code against the project's design system and keep the two in sync. Checks that code follows the design tokens, shared components and page type rules; that code was migrated after the design system changed; and that DESIGN.md matches the tokens file. Classifies every finding as a violation, a system gap or an outdated system, and reports with file and line evidence. Use when reviewing a pull request, branch or diff that touches UI, after design tokens or DESIGN.md change, before...

Shape UI composition, visual finish, task usability, and interaction evidence as a bounded supplement to the selected delivery workflow.
