What is palette CLAUDE.md?

A project instruction file for Claude Code, an AI coding assistant. It explains Palette, an MCP server that turns Figma designs into React or Vue components using a shared design system, and lists its commands and structure.

Working on Palette, including installing dependencies, building it, running its MCP server, developing with hot reload, and running its test groups.

It gives the coding assistant project-specific context instead of making it infer how to install, build, test, and run the project.

Token cost

What it costs to keep this loaded

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	$0.00959	$0.00959
Opus 5.5	$0.00384	$0.00384

Security

Grade A, and why

palette CLAUDE.md 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 2mo 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.

Project Overview

Palette is an MCP (Model Context Protocol) server that converts Figma designs to React/Vue components using the Dealicious Design System. It acts as a bridge between Figma and code generation, ensuring all generated components use the internal design system.

Common Commands

# Install dependencies
yarn install

# Build the project
yarn build

# Start the MCP server
yarn start

# Development mode (with hot reload)
yarn dev

# Run tests
yarn test

# Test services
yarn test:services

# Test Figma tools
yarn test:figma-tools

# Test MCP servers
yarn test:mcp-servers

├── services/
│   ├── figma.ts               # Figma data fetching (MCP-first with REST API fallback)
│   ├── design-system.ts       # Design system component registry and mapping

└── utils/

MCP Tools

The server exposes four tools:

convert_figma_to_react - Convert Figma design to React component
convert_figma_to_vue - Convert Figma design to Vue component
list_design_system_components - List available design system components
analyze_figma_file - Analyze Figma file structure

Data Flow

Figma Data Fetching: FigmaService fetches data via Figma Desktop MCP (priority) or REST API (fallback)
Component Mapping: DesignSystemService maps Figma nodes to design system components
Code Generation: CodeGenerator produces React/Vue code with HTML/image previews

Critical Rules

Rule 1: Figma Access via MCP Only

When working with Figma data:

MUST USE: list_mcp_resources or fetch_mcp_resource tools
NEVER: Direct Figma API calls (fetch('https://api.figma.com/...'))
NEVER: Ask users to copy/paste from Figma

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.
