hig-doctor

Audits interface source code (Swift, UIKit, AppKit, React, Vue, Svelte, Angular, Compose, Android XML, Flutter, CSS, HTML) for Apple HIG-aligned interface and accessibility problems by running the HIG Doctor CLI, then reports findings by severity and helps remediate them. Review evidence, not certification.

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.
1 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by podo on GitHub. Read the source before you install it.

Installation

Install the Hig Doctor 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/podo/design-agent-skills/tree/main/skills/hig-doctor
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/podo/design-agent-skills.git /tmp/design-agent-skills
mkdir -p .claude/skills
cp -r /tmp/design-agent-skills/skills/hig-doctor .claude/skills/hig-doctor

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

Use it in TypingMind

Enable Hig Doctor 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 Hig Doctor 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 Hig Doctor 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.

hig-doctor

Catalogue stub — full skill: raintree-technology/hig-doctor

Decision tree

Is the full skill already installed? Upstream names this skill hig-doctor-audit, so it installs next to this pointer (the pointer is not replaced).
- Global: f=~/.agents/skills/hig-doctor-audit/SKILL.md; [ -f "$f" ] && ! grep -q "^das:" "$f" && echo "installed" || echo "pointer"
- Project: f=.agents/skills/hig-doctor-audit/SKILL.md; [ -f "$f" ] && ! grep -q "^das:" "$f" && echo "installed" || echo "pointer"
- installed → the skill is installed as hig-doctor-audit, invoke it and proceed
- pointer → go to step 2

Detect scope, then install:

bash
[ -e ~/.agents/skills/hig-doctor ] && echo "global" || echo "project"

Global:

bash
npx skills add raintree-technology/hig-doctor/plugin/skills/hig-doctor-audit -g -y

Project:

bash
npx skills add raintree-technology/hig-doctor/plugin/skills/hig-doctor-audit -y

Claude Code: send a command as a chat message starting with ! to run it without leaving the conversation.

Heads-up

Requires: Node.js with npx and npm registry access at audit time (the skill runs a version-pinned npx -y hig-doctor@<version> <target> --json); optional companion for the guidance behind each finding: the apple-hig-skills pointer (the hig-* reference skills)
License: MIT (tooling; Apple reference content is attributed, see upstream THIRD_PARTY_NOTICES.md)

Invoke after install

Skill name: hig-doctor-audit
Trigger phrases: "HIG compliance", "Apple HIG audit", "scan this code for HIG issues", "fix Apple HIG"

What it does

A scan-and-remediate workflow around the HIG Doctor CLI. Given a repository or directory, it runs the version-pinned npx -y hig-doctor@<version> <target> --json, reports the detected frameworks, severity counts, rule IDs, locations and analysis limits, separates mechanical fixes from changes that need product, design or accessibility judgment, and, if you authorise remediation, fixes and re-runs the audit. It preserves justified suppressions and baselines and never claims that a scan proves HIG compliance. It does nothing useful without source code to audit.

Needs Node.js with npx and npm registry access. The guidance behind each finding comes from the HIG reference skills, which are a separate pointer: apple-hig-skills.

When NOT to use

General Apple design advice with no source to audit — use apple-hig-skills (the hig-* reference skills)
SwiftUI implementation help — use swiftui-patterns or swiftui-claude-skills
Web accessibility conformance audits — use wcag-audit-patterns

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 Hig Doctor AI skill do?

Why use Hig Doctor on TypingMind?

Because you install it once and use it with any model. Hig Doctor 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 Hig Doctor in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/podo/design-agent-skills/tree/main/skills/hig-doctor. 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 Hig Doctor?

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 Hig Doctor?

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

Is the Hig Doctor AI skill free?

Yes. It is published on GitHub by podo 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.
