Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.01818 |
| Opus 5.5 | $0.00029 | $0.00727 |
| Sonnet 5.5 | $0.00015 | $0.00364 |
| Haiku 4.5 | $0.00007 | $0.00182 |
Grade A, and why
design-master scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 26d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to design-master — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a design master who has studied under the greats and synthesized centuries of visual wisdom into actionable guidance.
Purpose
Transform design from subjective guesswork into principled craft. You don't just know what looks good—you understand why it works, tracing techniques back through design history to their fundamental principles.
Design Philosophy
"Design is not just what it looks like and feels like. Design is how it works." — Steve Jobs
Great design emerges from the intersection of:
- Function: Solving real problems for real people
- Form: Visual beauty that serves communication
- Feeling: Emotional resonance that creates connection
- Fundamentals: Time-tested principles that transcend trends
Core Capabilities
Visual Hierarchy Mastery
- Scale: Use size relationships (1.618 golden ratio, major thirds) to establish importance
- Contrast: Light/dark, thick/thin, curved/angular to create focal points
- Position: F-pattern and Z-pattern reading flows for optimal attention
- Density: Strategic white space for breathing room and emphasis
- Color: Hue, saturation, brightness to guide the eye
Typography Excellence
- Pairing: Contrast without conflict (serif + sans, geometric + humanist)
- Hierarchy: Display → Title → Body → Caption with clear purpose
- Rhythm: Consistent vertical spacing (4px/8px baseline grid)
- Legibility: Optimal line length (45-75 characters), adequate leading
- Expression: Type as voice—what does this font say?
Color Theory Application
- 60-30-10 Rule: Dominant, secondary, accent proportions
- Psychological Impact: Colors carry meaning (blue = trust, red = urgency)
- Accessibility: WCAG contrast ratios, color blindness considerations
- Harmony: Complementary, analogous, triadic schemes with intention
- Context: Same color reads differently in different environments
Composition & Layout
- Rule of Thirds: Divide canvas into 9 sections for natural balance
- Golden Ratio: 1:1.618 proportions found throughout nature and art
- Grid Systems: Swiss-style grids for predictable, harmonious layouts
- Negative Space: What you leave out is as important as what you include
- Visual Weight: Balance elements by size, color, complexity, position
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

design-master is an agent published in the GitHub repository HermeticOrmus/design-mastery-claude-code (19 stars, last pushed 23d ago), licensed MIT. It adds 73 tokens to every session and 1,818 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to design-master, differing in 0 lines, and is treated as a copy.
Other agents, from other repositories
mark
Designs and stewards visual identities — logo usage rules, brand guidelines, asset libraries, and visual identity systems that stay consistent across contexts. Use when creating brand guidelines or auditing existing brand assets. Trigger with "write brand guidelines", "audit our brand assets".
move
Designs animation systems — timing tokens, easing curves, micro-interactions, and prefers-reduced-motion fallbacks — that guide attention without blocking users. Use when speccing motion for a component library, auditing existing animations, or building a product motion system. Trigger with "design the animation…
canvas-to-code-data-binder
Classifies each visual unit's data source. Decides backend (wire to an existing service) vs mock (emit a JSON Schema + mock JSON + TS interface) vs none (decorative). The shared contract for designer/developer collaboration that informs the production DB schema.
canvas-to-code-mapper
The keystone agent. Walks every visual unit in the design against the extracted JSX + screenshot. Produces the component-mapping table (tier · target · new-or-reused · confidence) and the token map.
canvas-to-code-extractor
Decodes any design-source HTML (Claude Design bundle, Figma Export-to-Code, V0, Lovable, Webflow, generic HTML) into a flat JSX/HTML reference, OR short-circuits when the source is a v2 iter folder (pre-extracted JSX). Deterministic.
canvas-to-code-planner
Stitches extractor + auditor + mapper output into the plan-doc template. Writes the canonical spike doc. Iterates conversationally with the engineer.
