Is the Tufte skill free?

Yes. The skill itself is free from aref-vc/tufte-claude-skill. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Tufte SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install Tufte?

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 Tufte 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: Tested · Works
Score: 9.2/10
Tested: Jul 31, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 52c2e2b

Fetched SKILL.md (repo root) plus principles.md, chart-selection.md, kill-list.md, checklist.md, and presets/html-svg.md — all HTTP 200 with substantive, non-placeholder content and real SVG code. For the output test I built two charts of the same 5-product-line revenue data: a baseline (my default) and one strictly following presets/html-svg.md. Baseline used vertical bars in as-input order, a 5-hue qualitative palette, a gradient def, a drop-shadow filter, an SVG border box, five gridlines, a separate legend, and printed no values. The skill version was a dot plot sorted descending (Pulse 560 down to Orbit 260), Tufte ink-on-paper palette, exact numbers printed beside each dot via direct labels (no legend), a range frame with one faint gridline, and the single red accent applied only to the leader — matching the skill's kill-list and keep-list exactly. No security smells found.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 5/5
Triggers reliably 5/5
Output vs. baseline 8/10

What Tufte does

Turns any chart, dashboard, KPI tile, or infographic request into a Tufte-compliant design, outputting self-contained HTML/SVG or React (Recharts/D3). Bundles a 10-principle reference, a data-to-chart-type selection table, a chartjunk kill-list, a pre-publish checklist, and working SVG presets for dot plots, sparklines, line charts, and small multiples. Triggers on chart, graph, dashboard, infographic, visualize, data viz, or Tufte.

How to install Tufte

git clone --depth 1 https://github.com/aref-vc/tufte-claude-skill.git /tmp/tufte-src
mkdir -p ~/.claude/skills/tufte
cp -R /tmp/tufte-src/. ~/.claude/skills/tufte/
# SKILL.md is at the repo root; the copy above places it at ~/.claude/skills/tufte/SKILL.md
# No external deps, API keys, or scripts. Reference files (principles.md, chart-selection.md,
# kill-list.md, checklist.md, presets/*.md) and assets are read on demand by the skill body.

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