Design System Builder — Figma MCP Skill

Build professional-grade design systems in Figma that match code. This skill orchestrates multi-phase workflows across 20–100+ use_figma calls, enforcing quality patterns from real-world design systems (Material 3, Polaris, Figma UI3, Simple DS).

Prerequisites: The figma-use skill MUST also be loaded for every use_figma call. It provides Plugin API syntax rules (return pattern, page reset, ID return, font loading, color range). This skill provides design system domain knowledge and workflow orchestration.

Always pass skillNames: "figma-generate-library" when calling use_figma as part of this skill. This is a logging parameter — it does not affect execution.

1. The One Rule That Matters Most

This is NEVER a one-shot task. Building a design system requires 20–100+ use_figma calls across multiple phases, with mandatory user checkpoints between them. Any attempt to create everything in one call WILL produce broken, incomplete, or unrecoverable results. Break every operation to the smallest useful unit, validate, get feedback, proceed.

2. Mandatory Workflow

Every design system build follows this phase order. Skipping or reordering phases causes structural failures that are expensive to undo.
