Quick Start

Claude Code

# 1. Add the cc-design marketplace
/plugin marketplace add ZeroZ-lab/cc-design

# 2. Install the plugin
/plugin install cc-design@cc-design

# 3. Reload plugins to activate
/reload-plugins

After installation, cc-design activates via /cc-design:design command.

Codex

# 1. Add the cc-design marketplace from GitHub
/plugin marketplace add ZeroZ-lab/cc-design

# 2. Install the plugin
/plugin install cc-design@cc-design

# 3. Reload plugins to activate
/reload-plugins

After installation, cc-design activates via $cc-design reference.

Example prompts

"Design a landing page for our SaaS product"
"Create a 10-slide pitch deck for the Q3 board meeting"
"Build an interactive prototype of the checkout flow"
"Create an interactive explainer showing how our RAG pipeline works"
"Make a comparison explainer for React vs Vue"
"Build a decision tree for tech stack selection"
"Animate this logo reveal with the Pentagram style"
"Export the deck as editable PPTX"

cc-design handles context gathering, design planning, quality checks, and verification — you approve the plan, it builds.

Showcase

Capabilities

Category	What you get
Design outputs	Landing pages, slide decks, interactive prototypes, interactive explainers (flow, compare, decision tree), wireframes, animations, design systems, motion studies
Design thinking	8-layer framework (Goal → Validation), 10 core principles, 20 philosophy schools
Brand cloning	Progressive loading of 68+ brand design systems from getdesign.md
Quality guardrails	Anti-AI slop rules, typography system, spacing scale, mandatory screenshot verification
Variations	3+ design directions across layout, interaction, visual intensity, and motion
Export	PDF (multi-file + single-file), PPTX (image + editable), MP4 video, inline HTML
Audio	Dual-track audio (SFX + BGM), 37 SFX catalog, ffmpeg mixing
Design review	5-dimension scoring: philosophy, hierarchy, craft, functionality, originality
Animation	Stage+Sprite timeline engine, easing library, Seek-First numerical verification (__seek + getComputedStyle), signal protocol, pitfall guardrails
Prototyping	React + Babel inline JSX, device frames (iOS, Android, macOS, browser)

Design Styles

Mention a philosophy school to set the direction:

"Use the Pentagram style for this infographic"
"Apply Experimental Jetset minimalism to this poster"
"Mix Takram restraint with Locomotive motion for the hero"

20 schools across 5 traditions — Information Architects, Motion Poets, Minimalists, Experimental Vanguard, Eastern Philosophy. See references/design-styles.md.

Brand Style Cloning

Mention a brand name to load its design system:

"Create a pricing page with Stripe's aesthetic"
"Notion-style kanban board"
"Mix Vercel's minimalism with Linear's purple accents"

How It Works

Understand → Route → Plan → Approve → Build → Verify → Deliver

1. Understand — cc-design asks targeted questions to lock the output type, audience, and constraints
2. Plan — presents a visible execution plan with goals, facts, and assumptions
3. Approve — you approve before any code is written
4. Build — per-section preview pattern; you approve section by section
5. Verify — three-phase self-check (structural, visual, design excellence)
6. Deliver — screenshot-verified artifact ready to use

Key behavioral guarantees:

• Never builds without an approved plan
• Never delivers without screenshot verification
• Never uses AI slop patterns (banned gradients, emoji spam, generic layouts)
• Follow-ups and minor edits skip the full discovery flow

Optional Dependencies

Core installation has no extra dependencies. For export features:

# Playwright browser (for export and verification)
npx playwright install chromium

# Video and audio export
brew install ffmpeg          # macOS
sudo apt install ffmpeg      # Ubuntu/Debian
choco install ffmpeg         # Windows

Platform Integration

Platform	Activation	Integration
Claude Code	/design command	Commands + SKILL.md
Codex / OpenAI	$cc-design reference	agents/openai.yaml

Contributing

1. Fork the repo, create a feature branch
2. Keep SKILL.md under 200 lines — move technical content to references/
3. Add new references to load-manifest.json and the routing table in SKILL.md
4. Run node scripts/lint-load-manifest.mjs and node scripts/generate-bundle-catalog.mjs
5. If changing first-turn behavior: update VERSION, SKILL.md, README.md, references/workflow.md, then run ./scripts/check-behavior-contract.sh <base-ref>
