Bridge DS

AI-powered design generation in Figma — 100% design system compliant.

Bridge turns Claude Code into a designer that knows your design system inside out. It extracts, documents, and uses your real Figma components, tokens, and text styles to generate production-ready designs.

You describe what you want
  → Claude consults the knowledge base (your DS, documented)
  → Claude writes the spec (exact components, tokens, layout)
  → Claude generates in Figma via figma_execute (real DS components, bound variables)
  → You review in Figma

How it works

Bridge is two things:

1. A CLI (bridge-ds init) that scaffolds your project with the design workflow skill
2. A Claude Code skill (/design-workflow) that handles the intelligence — spec writing, DS knowledge, Figma generation

The transport layer is figma-console-mcp, an MCP server that gives Claude native access to Figma (57+ tools).

                                                            (your DS library,
                                                             real components,
                                                             bound variables)

Prerequisites

• Claude Code installed
• Node.js 18+
• Figma Desktop (not the web app)
• A Figma file with a published design system library

Quick Start

1. Install figma-console-mcp

claude mcp add figma-console -s user \
  -e FIGMA_ACCESS_TOKEN=figd_YOUR_TOKEN \
  -- npx -y figma-console-mcp@latest

Get your token from Figma Settings → Personal access tokens.

2. Connect Figma Desktop

1. Run npx figma-console-mcp@latest --print-path to find the plugin directory
2. In Figma Desktop: Plugins → Development → Import plugin from manifest...
3. Select figma-desktop-bridge/manifest.json
4. Run the plugin in your Figma file

3. Initialize your project

cd your-project
npx @noemuch/bridge-ds init

This scaffolds:

• .claude/skills/design-workflow/ — the workflow skill + references
• .claude/commands/design-workflow.md — the /design-workflow slash command
• specs/ — directory for active, shipped, and dropped specs

4. Build your knowledge base

Open Claude Code in your project:

/design-workflow setup

Claude will:

1. Extract your entire DS from Figma (figma_get_design_system_kit)
2. Analyze every component, token, and style
3. Generate intelligent guides (when to use what, decision trees, pattern catalog)
4. Ask for product screenshots to document layout patterns

5. Start designing

/design-workflow spec a settings page for account information

Claude consults the knowledge base, identifies the right pattern, components, and tokens, and writes a complete spec. Then:

/design-workflow design    # Generate in Figma (atomic, verified)
/design-workflow review    # Validate against spec
/design-workflow done      # Archive and ship

The Workflow

setup (once)  →  spec  →  design  →  review  ──→  done
                   ↑                    |             |
                   └── iterate ─────────┘       learn ←┘
                                           (diff corrections,
                                            extract preferences)

Spec-first

No design without a validated specification. Claude knows exactly which components, tokens, and layout patterns to use because it has your DS documented.

Atomic generation

Designs are generated in 4-6 small sequential scripts (~30-80 lines each). After each step, Claude takes a screenshot and verifies before continuing. Bug in step 3? Fix and re-run step 3 only.

DS-native

Zero hardcoded hex colors. Zero recreated components. Everything imported from your library via importComponentByKeyAsync, bound to variables via setBoundVariableForPaint.

Quality gates

Blocking checks at every phase transition: spec validation, pattern matching, pre-script element audit, visual fidelity review, DS component reuse audit.

Knowledge Base

The knowledge base is what makes Bridge different from "just executing Figma scripts". During setup, Claude builds a complete understanding of your DS:

knowledge-base/
  registries/          ← Raw DS data (components, variables, text styles)
  guides/
    design-patterns.md ← Layout patterns from your product screenshots
    tokens/            ← When to use which color, spacing, typography
    components/        ← Decision tree: "I need X" → use component Y
    patterns/          ← Form, navigation, feedback, multi-step patterns
    assets/            ← Icons, logos, illustrations catalog
  ui-references/       ← Product screenshots for pattern extraction
