lint-design-figma

Lint a Figma node tree for WCAG 2.2 accessibility AND design-system quality — contrast, target size, focus indicators, color-only signaling, hardcoded colors, missing text styles, detached components, and more. Use when the user wants a design-side audit BEFORE handoff: triggers 'lint this frame', 'check accessibility', 'WCAG audit', 'is my design accessible', 'find contrast issues', 'check color contrast', 'find hardcoded colors', 'are my components using tokens', 'design QA', 'a11y check on this page', 'audit my design for issues'. Walks the tree from a node (or the whole page) and returns findings with severity (critical/warning/info) and WCAG level (A/AA/AAA/best-practice). The native Figma MCP has NO design-side linting — this is unique to this collection. For the deep per-component a11y scorecard use audit-accessibility-figma; for CODE-side (HTML) checks use scan-code-accessibility-figma.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
2 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by southleft on GitHub. Read the source before you install it.

Installation

Install the Lint Design Figma AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/southleft/skills-for-figma/tree/main/skills/lint-design-figma
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/southleft/skills-for-figma.git /tmp/skills-for-figma
mkdir -p .claude/skills
cp -r /tmp/skills-for-figma/skills/lint-design-figma .claude/skills/lint-design-figma

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Lint Design Figma in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Lint Design Figma on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Lint Design Figma is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

lint-design-figma — WCAG 2.2 + design-system lint over a node tree

Walk a Figma node (or the whole current page) and report accessibility and design-quality problems in one pass. Runs entirely through use_figma, so it works on any Figma plan and inspects the real design (true colors, real auto-layout, actual variant names) rather than generated code.

Why this is unique: the native Figma MCP (get_design_context, get_metadata, etc.) reads designs for code generation but does not lint them. There is no built-in "is this accessible / token-clean?" check on the design side. This skill fills that gap with a faithful port of 14 WCAG 2.2 rules plus 6 design-system/layout rules.

Skill boundaries

use_figma rules — load the official figma-use skill first; it is the full Figma Plugin API reference. Essentials these scripts rely on: plain JS with top-level await + return (no IIFE, no figma.closePlugin(); console.log is not returned), inputs inlined as const at the top of each script, colors in 0–1 range, load fonts before any text op, await figma.getNodeByIdAsync(...), and atomic errors (a failed script applies nothing — read the error, fix, retry).
Per-component deep scorecard (state coverage, color-blind sim, 0–100 scores) → use audit-accessibility-figma.
CODE-side a11y (axe-core over generated HTML) → use scan-code-accessibility-figma.
Design-vs-code drift → use check-design-parity-figma.

Workflow

Pick the scope. Get the target NODE_ID (a frame, component set, or screen) from the user's selection or a URL. Leave it null to lint the entire current page.
Pick the rules. RULES defaults to ['all']. Narrow it to a group ('wcag', 'design-system', 'layout') or a specific rule id (e.g. 'wcag-contrast') to cut noise. The full catalog is in references/lint-rules.md.
Run scripts/lint-design.js via use_figma (skillNames: "lint-design-figma"). Edit the const inputs at the top first.
Triage by severity. The result groups findings by rule, each carrying severity (critical/warning/info) and wcagLevel (a/aa/aaa/best-practice/design-system). Lead with critical (contrast, target size, focus, color-only).
Fix + re-lint. Apply fixes (via manage-variables-figma, figma-use, etc.) and re-run the same scope to confirm summary.total dropped. Each finding includes the offending node.id so you can jump straight to it.

Key rules

Colors are 0–1 floats. Contrast math uses sRGB linearization + relative luminance; the script ships its own helpers (no hex needed for input).
Background is inferred by walking ancestors for the nearest solid fill (defaults to white). Contrast on semi-transparent fills is flagged approximate: true.
MAX_DEPTH (default 10) and MAX_FINDINGS (default 100) bound the walk. If truncated is set, narrow the scope or raise the cap.
WCAG-honest severity: some rules (text size, line height, letter/paragraph spacing) are labelled best-practice, not a hard WCAG failure — see lint-rules.md for the exact reasoning per rule.
Findings are descriptive, not auto-fixed. Confirm intent before bulk-editing a design.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Lint Design Figma AI skill do?

Why use Lint Design Figma on TypingMind?

Because you install it once and use it with any model. Lint Design Figma is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Lint Design Figma in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/southleft/skills-for-figma/tree/main/skills/lint-design-figma. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Lint Design Figma?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Lint Design Figma?

As many as you like. As long as a model supports skills, you can use Lint Design Figma with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Lint Design Figma AI skill free?

Yes. It is published on GitHub by southleft under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
