Is the FigJam Builder skill free?

Yes. The skill itself is free from prasantloki/figjam-builder. SkillProof publishes the install command and an independent test verdict at no cost.

What is the FigJam Builder SkillProof Score?

8.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 5/5.

How do I install FigJam Builder?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use FigJam Builder with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 8.8/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 7c1b0d4

Genuinely sharp design-system prompt (exact type scale ranges, a disciplined 3-tier color-by-hue palette, and it calls out the single most common Plugin-API bug - adding section.x to a child's already-section-relative offset - by name), but it is unusable out of the GitHub clone alone: SKILL.md itself says to load `figma-plugin:figma-use` and `figma-plugin:figma-use-figjam` first, and neither companion skill nor any Figma MCP tool ships in this repo or was available to test with.

What FigJam Builder does

A prompt-only skill that teaches Claude a full FigJam design system - type scale by role, a three-tier accent/vibrant/muted color palette, a 4px spacing grid, section-local coordinate rules, and an audit checklist - then applies it to build new boards or edit existing ones through Figma's Plugin API. Triggers on FigJam build/edit/layout-fix requests or any shared figma.com/board URL, but explicitly requires the separate `figma-plugin:figma-use` and `figma-plugin:figma-use-figjam` companion skills plus live Figma MCP tools (`use_figma`, `get_figjam`, etc.) that are not bundled in this repository.

How to install FigJam Builder

git clone https://github.com/prasantloki/figjam-builder
mkdir -p ~/.claude/skills
cp -r figjam-builder ~/.claude/skills/figjam-builder
# ALSO REQUIRED, not included in this repo: a Figma MCP server exposing use_figma/get_figjam/upload_assets/create_new_file/generate_diagram, plus the figma-plugin:figma-use, figma-plugin:figma-use-figjam, and figma-generate-diagram companion skills.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger FigJam Builder

/figjam-builder A visual-design rulebook (type scale, color tiers, spacing grid) for building or editing FigJam boards via the Figma Plugin API.

It also activates on plain-language prompts like these:

Build a three-zone decision board comparing Postgres and DynamoDB
Fix the spacing and color tiers on this existing FigJam board
Lay out a FigJam board using our type scale and 4px spacing grid
