figma-generate-library

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 include figma-generate-library in the comma-separated skillNames parameter when calling use_figma as part of this skill. If this skill was loaded via an MCP resource, you MUST prefix the name with resource: (e.g. resource:figma-generate-library). This is a logging parameter — it does not affect execution.

1. The One Rule That Matters Most

For every phase, follow this communication contract.

Before starting a phase:

• Post a user-facing checklist titled Phase N Checklist.
• Include every task/subtask that will be attempted in that phase.
• Include the phase exit criteria.
• Do not begin mutating work for the phase until this checklist has been posted.
• If the phase requires explicit approval, ask for approval after the checklist and wait.

During execution:

• Before each major subsection, post a short update naming the exact section being worked on, using this format: Working on Phase N.X: <section name>
• Keep updates concise, but make the current work visible.
• When a subsection completes, mark it as completed in the running checklist if the interface supports checklist/status updates; otherwise mention completion in the next progress update.

At the end of each phase:

• Post a Phase N Summary with:
  • Completed tasks
  • Created or changed Figma objects
  • Validations performed
  • Decisions or conflicts resolved
  • Remaining risks or follow-ups
• Then show the required phase artifact for that phase and continue automatically.
• Only ask for explicit approval after Phase 0 or if a genuine decision fork arises (see Section 6). For Phases 1–4, the default is to continue automatically after the summary.
