Implement Design

Overview

This skill provides a structured workflow for translating Figma designs into production-ready code with pixel-perfect accuracy. It ensures consistent integration with the Figma MCP server, proper use of design tokens, and 1:1 visual parity with designs.

Skill Boundaries

• Use this skill when the deliverable is code in the user's repository.
• If the user asks to create/edit/delete nodes inside Figma itself, switch to figma-use.
• If the user asks to build or update a full-page screen in Figma from code or a description, switch to figma-generate-design.
• If the user asks only for Code Connect mappings, switch to figma-code-connect-components.
• If the user asks to author reusable agent rules (CLAUDE.md/AGENTS.md), switch to figma-create-design-system-rules.

Prerequisites

• Figma MCP server must be connected and accessible
  • Before proceeding, verify the Figma MCP server is connected by checking if Figma MCP tools (e.g., get_design_context) are available.
  • If the tools are not available, the Figma MCP server may not be enabled. Guide the user to enable the Figma MCP server that is included with the plugin. They may need to restart their MCP client afterward.
• User must provide a Figma URL in the format: https://figma.com/design/:fileKey/:fileName?node-id=1-2
  • :fileKey is the file key
  • 1-2 is the node ID (the specific component or frame to implement)
• OR when using figma-desktop MCP: User can select a node directly in the Figma desktop app (no URL required)
• OR when using figma-desktop MCP: User can select a node directly in the Figma desktop app (no URL required)
• Project should have an established design system or component library (preferred)

Required Workflow

Follow these steps in order. Do not skip steps.

Step 0: Set up Figma MCP (if not already configured)

VS Code + GitHub Copilot users: Figma MCP is pre-configured in .vscode/mcp.json - skip to Step 1. If tools are still unavailable, reload the VS Code window and check the MCP panel.

Claude Code / Codex CLI users: If any MCP call fails because Figma MCP is not connected, pause and set it up:

1. Add the Figma MCP:
   • codex mcp add figma --url https://mcp.figma.com/mcp
2. Enable remote MCP client:
   • Set [features].rmcp_client = true in config.toml or run codex --enable rmcp_client
3. Log in with OAuth:
   • codex mcp login figma

After successful login, the user will have to restart codex. You should finish your answer and tell them so when they try again they can continue with Step 1.

Step 1: Get Node ID

Option A: Parse from Figma URL

When the user provides a Figma URL, extract the file key and node ID to pass as arguments to MCP tools.

URL format: https://figma.com/design/:fileKey/:fileName?node-id=1-2

Extract:

• File key: :fileKey (the segment after /design/)
• Node ID: 1-2 (the value of the node-id query parameter)

Note: When using the local desktop MCP (figma-desktop), fileKey is not passed as a parameter to tool calls. The server automatically uses the currently open file, so only nodeId is needed.

Example:

• URL: https://figma.com/design/kL9xQn2VwM8pYrTb4ZcHjF/DesignSystem?node-id=42-15
• File key: kL9xQn2VwM8pYrTb4ZcHjF
• Node ID: 42-15

Option B: Use Current Selection from Figma Desktop App (figma-desktop MCP only)

When using the figma-desktop MCP and the user has NOT provided a URL, the tools automatically use the currently selected node from the open Figma file in the desktop app.

Note: Selection-based prompting only works with the figma-desktop MCP server. The remote server requires a link to a frame or layer to extract context. The user must have the Figma desktop app open with a node selected.

Step 2: Fetch Design Context

Run get_design_context with the extracted file key and node ID.

get_design_context(fileKey=":fileKey", nodeId="1-2")

This provides the structured data including:

• Layout properties (Auto Layout, constraints, sizing)
• Typography specifications
• Color values and design tokens
• Component structure and variants
• Spacing and padding values

If the response is too large or truncated:

1. Run get_metadata(fileKey=":fileKey", nodeId="1-2") to get the high-level node map
2. Identify the specific child nodes needed from the metadata
3. Fetch individual child nodes with get_design_context(fileKey=":fileKey", nodeId=":childNodeId")

Step 3: Capture Visual Reference

Run get_screenshot with the same file key and node ID for a visual reference.

get_screenshot(fileKey=":fileKey", nodeId="1-2")

This screenshot serves as the source of truth for visual validation. Keep it accessible throughout implementation.

Step 4: Download Required Assets

Download any assets (images, icons, SVGs) returned by the Figma MCP server.

IMPORTANT: Follow these asset rules:

• If the Figma MCP server returns a localhost source for an image or SVG, use that source directly
• DO NOT import or add new icon packages - all assets should come from the Figma payload
• DO NOT use or create placeholders if a localhost source is provided
• Assets are served through the Figma MCP server's built-in assets endpoint

Project asset and style file locations:

Type	Location
Images / icons (Vite-processed, imported in TS)	src/client/assets/images/ or src/client/assets/icons/
Static fonts referenced by URL in CSS	public/fonts/
DSAI design tokens (CSS custom properties)	src/generated/css/tokens.css and tokens-dark.css
Bootstrap theme with DSAI overrides	src/generated/css/dsai-theme-bs.css
Custom CSS (keyframes, @font-face, overrides)	src/client/custom.css

Step 5: Translate to Project Conventions

CRITICAL: NEVER output Tailwind CSS. The Figma MCP generates React + Tailwind by default. You MUST convert ALL Tailwind classes to Bootstrap 5 utilities and DSAI tokens before writing any code. No Tailwind class should appear in the final output.

Tailwind → Bootstrap/DSAI Conversion Reference

Tailwind	Bootstrap 5 / DSAI Equivalent
flex	d-flex
flex-col	flex-column
items-center	align-items-center
justify-between	justify-content-between
gap-4	gap-3 (Bootstrap scale)
p-4	p-3 (Bootstrap scale)
mt-2	mt-2 (same scale name, different values)
rounded-lg	rounded or var(--dsai-border-radius)
shadow-md	var(--dsai-shadow-default)
text-sm	fs-6 or var(--dsai-font-size-sm)
text-gray-500	text-body-secondary or var(--dsai-color-neutral-500)
bg-white	bg-body or var(--dsai-bg-surface)
sr-only	visually-hidden
hover:bg-gray-100	Use FSM state + cn() conditional class

Translate the Figma output into this project's framework, styles, and conventions.

Key principles:

• Treat the Figma MCP output (typically React + Tailwind) as a representation of design and behavior, not as final code style
• Replace Tailwind utility classes with Bootstrap 5 utilities and DSAI CSS custom properties (var(--dsai-*))
• Reuse DSAI components (Button, Input, Card, Modal, etc.) from @/components/ui/ instead of creating new ones
• Use DSAI semantic color tokens (var(--dsai-color-primary), etc.) and Bootstrap spacing utilities (m-3, p-2, gap-3)
• Use cn() from @/lib/utils for class name composition (simple filter+join, not tailwind-merge)
• Respect existing routing, state management, and data-fetch patterns

Step 6: Achieve 1:1 Visual Parity

Strive for pixel-perfect visual parity with the Figma design.

Guidelines:

• Prioritize Figma fidelity to match designs exactly
• Avoid hardcoded values - use design tokens from Figma where available
• When conflicts arise between design system tokens and Figma specs, prefer design system tokens but adjust spacing or sizes minimally to match visuals
• Follow WCAG requirements for accessibility
• Add component documentation as needed

Step 7: Validate Against Figma

Before marking complete, validate the final UI against the Figma screenshot.

Validation checklist:

• Layout matches (spacing, alignment, sizing)
• Typography matches (font, size, weight, line height)
• Colors match exactly
• Interactive states work as designed (hover, active, disabled)
• Responsive behavior follows Figma constraints
• Assets render correctly
• Accessibility standards met

Implementation Rules

Component Organization

• DSAI components live in src/client/components/ui/ — they are local source code you own (installed via dsai add)
• Place app-specific components in src/client/components/ that compose DSAI components from @/components/ui/
• Use named exports only — no default exports
• Component names must be PascalCase; file names must match the component name
• Every component uses forwardRef + displayName (DSAI convention)
• Never use inline style={} when an equivalent Bootstrap utility class exists
• Use cn() from @/lib/utils for conditional class merging (simple filter+join)

Design System Integration

• ALWAYS check src/client/components/ui/ for an existing DSAI component before creating a new one
• Map Figma design tokens to DSAI tokens: colors via var(--dsai-color-*), typography via var(--dsai-font-*), spacing via Bootstrap scale
• When a matching DSAI component exists, compose with it rather than duplicating
• Use cn() from @/lib/utils for all conditional class merging
• Run dsai add <component> if a needed component isn't installed yet

Code Quality

• Avoid hardcoded values - extract to constants or design tokens
• Keep components composable and reusable
• Add TypeScript types for component props

Examples

See design-implementation-scenarios.md for detailed scenarios including implementing a button component and building a complete dashboard layout from Figma designs.

Best Practices

Always Start with Context

Never implement based on assumptions. Always fetch get_design_context and get_screenshot first.

Incremental Validation

Validate frequently during implementation, not just at the end. This catches issues early.

Document Deviations

If you must deviate from the Figma design (e.g., for accessibility or technical constraints), document why in code comments.

Reuse Over Recreation

Always check for existing components before creating new ones. Consistency across the codebase is more important than exact Figma replication.

Design System First

When in doubt, prefer the project's design system patterns over literal Figma translation.

Common Issues and Solutions

See troubleshooting.md for solutions to common issues including truncated Figma output, design mismatches, asset loading problems, and design token discrepancies.

Understanding Design Implementation

The Figma implementation workflow establishes a reliable process for translating designs to code:

For designers: Confidence that implementations will match their designs with pixel-perfect accuracy. For developers: A structured approach that eliminates guesswork and reduces back-and-forth revisions. For teams: Consistent, high-quality implementations that maintain design system integrity.

By following this workflow, you ensure that every Figma design is implemented with the same level of care and attention to detail.

Arguments

When invoking this skill with arguments:

• $0 or $ARGUMENTS[0] - Figma URL in format https://figma.com/design/:fileKey/:fileName?node-id=1-2
  • The skill extracts :fileKey (file identifier) and 1-2 (node ID) from the URL
  • Example: /figma-implement-design https://figma.com/design/abc123/MyDesign?node-id=10-25
• $1 or $ARGUMENTS[1] - Optional explicit node-id override
  • Use when targeting a specific variant or nested component
  • Example: /figma-implement-design https://figma.com/design/abc123/MyDesign 10-25

If invoked without arguments, the skill will prompt for the Figma URL during execution.

Session Tracking

This skill uses ${CLAUDE_SESSION_ID} to track design implementation sessions:

// Each implementation is logged with session context
const sessionId = process.env.CLAUDE_SESSION_ID;
console.log(`[${sessionId}] Implementing Figma design: ${fileKey}, node: ${nodeId}`);

This allows correlation between:

• Design implementation start/completion
• MCP tool invocations (get_design_context, get_screenshot, get_assets)
• Git commits containing the implementation code
• Code review feedback and iterations

Use the session ID to trace the full lifecycle of a design implementation from Figma link to production code.
