design-mastersWorking profiles of Saul Bass, Massimo Vignelli, Dieter Rams, Paula Scher, Josef Müller-Brockmann, David Carson, and Paul Rand: key works, principles, and how to apply each in UI work.
Design Masters is an agent skill from HermeticOrmus/LibreUIUX-Claude-Code. Working profiles of Saul Bass, Massimo Vignelli, Dieter Rams, Paula Scher, Josef Müller-Brockmann, David Carson, and Paul Rand: key works, principles, and how to apply each in UI work. Use when a design needs a proven approach, a named reference to follow, or a lesson from a specific master.
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/david-carson.md`, `references/dieter-rams.md` and `references/josef-muller-brockmann.md`).
It sits in Frontend & Design. The repository describes itself as: UI/UX system for Claude Code: 71 plugins, 93 agents, 74 skills. Design mastery, archetypal design, accessibility, and frontend workflows in one validated plugin marketplace. The licence is MIT.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 41a968c. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Design Masters loads about 2.7k tokens when it runs, and up to ~15k if it reads all its reference files. Until then it costs about 77 tokens; SKILL.md has 1,155 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Domain: Film titles, corporate identity, posters Philosophy: "Design is thinking made visual"
Before adding detail, ask: "What's the one essential shape that captures this idea?"
Approach:
1. Identify the core concept
2. Find a visual metaphor
3. Reduce to essential geometry
4. Test if meaning survives reduction
5. Add nothing moreDomain: Information design, corporate identity, packaging Philosophy: "If you can design one thing, you can design everything"
Vignelli argued that a designer needs only a few basic typefaces. His 1991 exhibition "A Few Basic Typefaces" showed decades of work set in only four:
He also used Futura, and The Vignelli Canon allows a few more (Times among them) while holding that most typefaces exist for commercial reasons, not need.
Constrain your toolkit. A smaller palette forces smarter decisions.
Exercise:
1. Choose 2 fonts (one display, one body)
2. Choose 3 colors (primary, secondary, accent)
3. Choose 4 spacing values (4, 8, 16, 32px)
4. Design within these constraints
5. Notice how limitation creates cohesionDomain: Industrial design, Braun products Philosophy: "Less, but better" (Weniger, aber besser)
For any design element, ask:
Subtract until it breaks, then add back the minimum.
Process:
1. Design the full solution
2. Remove every element one by one
3. Note when functionality breaks
4. Restore only what's essential
5. Question if restoration can be simplerDomain: Typography, identity, environmental graphics Philosophy: "It's through mistakes that you actually can grow"
Rules are training wheels. Once you know them, ride freely.
Exercise:
1. Design something "correctly"
2. Now break one rule deliberately
3. Break another rule
4. Keep breaking until it's alive
5. Add structure back only where chaos defeats purposeDomain: Poster design, grid systems Philosophy: "The grid system is an aid, not a guarantee"
The grid is:
+---+---+---+---+---+---+
| | | | | | |
+---+---+---+---+---+---+
| | | | | | |
+---+---+---+---+---+---+
| | | | | | |
+---+---+---+---+---+---+
- Divide into equal columns
- Use consistent gutters
- Allow elements to span multiple units
- Create hierarchy through column usageBuild on a grid, but know when to break it.
Implementation:
1. Establish a 12-column grid
2. Define consistent gutters (e.g., 24px)
3. Align all elements to grid lines
4. When breaking grid, do so deliberately and obviously
5. Let grid create rhythm without monotonyDomain: Editorial design, experimental typography Philosophy: "Don't mistake legibility for communication"
When appropriate, prioritize feeling over reading.
Caution: Use sparingly
- Marketing that needs attention: YES
- Navigation: NO
- Legal text: NO
- Brand that demands conformity: NO
- Creative portfolio: YESDomain: Corporate identity, books, posters Philosophy: "Simplicity is not the goal. It is the by-product of a good idea."
From his essay "Logos, Flags, and Escutcheons" (1991):
Checks that follow from this (a working list, not Rand's wording): distinctive, legible at any size, adaptable across media, memorable, and durable beyond current trends.
A logo is a symbol for something. Find the something first.
| Designer | Core Strength | When to Reference |
|---|---|---|
| Bass | Symbolic reduction | Logo, poster, icon design |
| Vignelli | Systematic discipline | Information systems, identity |
| Rams | Essential minimalism | Product, interface, UX |
| Scher | Typographic expression | Environmental, branding, editorial |
| Brockmann | Grid harmony | Layout, publication, systematic design |
| Carson | Expressive chaos | Editorial, experimental, attention-grabbing |
| Rand | Logo perfection | Corporate identity, logomarks |
Read the matching profile when a task names a master or needs their method in depth. Each covers key works with dates, the principles to borrow, how to apply them in UI work, and common misreadings.

Design Masters fits situations like: A design needs a proven approach; A named reference to follow; A lesson from a specific master.
Run `npx skills add HermeticOrmus/LibreUIUX-Claude-Code --skill design-masters -a claude-code`. Or copy the skill folder (plugins/design-mastery/skills/design-masters in HermeticOrmus/LibreUIUX-Claude-Code) into .claude/skills/design-masters in your project. Claude Code loads it when a task matches its description.
Run `npx skills add HermeticOrmus/LibreUIUX-Claude-Code --skill design-masters -a codex`. Or copy the skill folder (plugins/design-mastery/skills/design-masters in HermeticOrmus/LibreUIUX-Claude-Code) into .agents/skills/design-masters in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add HermeticOrmus/LibreUIUX-Claude-Code --skill design-masters -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/design-masters, .gemini/skills/design-masters, .github/skills/design-masters and .opencode/skills/design-masters in your project.
SKILL.md names no scripts, command-line tools or credentials: Design Masters is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Design Masters is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.7k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 13k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Design Masters: Web Artifacts Builder (anthropics/skills, 180k stars), React Doctor (makeplane/plane, 61k stars), Impeccable (bestofjs/bestofjs, 3.1k stars) and Figma Design System Builder (warpdotdev/warp, 65k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
