gdd-sketch

Multi-variant HTML design exploration that creates .design/sketches/<slug>/ with N standalone variants (default 3), browser-openable directly via file:// without a build step. Use when answering 'what could this look like?' before committing to a direction.

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.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by hegemonart on GitHub. Read the source before you install it.

Installation

Install the Gdd Sketch 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/hegemonart/get-design-done/tree/main/scripts/skill-templates/sketch
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/hegemonart/get-design-done.git /tmp/get-design-done
mkdir -p .claude/skills
cp -r /tmp/get-design-done/scripts/skill-templates/sketch .claude/skills/gdd-sketch

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

Use it in TypingMind

Enable Gdd Sketch 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 Gdd Sketch 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 Gdd Sketch 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.

Get Design Done - Sketch

Role: Multi-variant HTML exploration. Answers "what could this look like?" by generating N standalone HTML variants from a topic prompt. Variants are browser-openable directly - no build step - and can be screenshot by Phase 8 Preview/Playwright tooling later.

Unlike {{command_prefix}}spike (which tests feasibility), {{command_prefix}}sketch explores visual/directional variants.

Flag parsing

Parse $ARGUMENTS:

[topic] → kebab-case slug (e.g., "hero-redesign")
--variants N → number of variants (default: 3)
--quick → skip intake, use DESIGN-CONTEXT.md tokens + sensible defaults

Step 1 - Intake (unless `--quick`)

AskUserQuestion, one at a time:

"What are you sketching? (component, layout, page)"
"What directions should the variants explore? (minimal/maximal, dense/spacious, flat/layered, playful/restrained, etc.)"
"Which design tokens apply? (pick from DESIGN-CONTEXT.md, or use defaults)"

If --quick: derive directions from topic + pull tokens from .design/DESIGN-CONTEXT.md if present, else defaults.

Step 2 - Create sketch directory

Derive <slug> from the topic (kebab-case).
mkdir -p .design/sketches/<slug>/ via Bash.

Step 3 - Write INTAKE.md

Write .design/sketches/<slug>/INTAKE.md with:

Topic
Directions (one bullet per variant)
Token references (link to DESIGN-CONTEXT.md or inline list)
Timestamp

Step 4 - Generate N standalone HTML variants

For each of N variants (default 3), write variant-<n>.html as a complete standalone HTML file:

<!DOCTYPE html> + <html> + <head> + <body>
<style> block inline with CSS custom properties for tokens (--color-*, --space-*, --font-*)
Semantic HTML5 (<header>, <main>, <nav>, <section>, etc.)
No imports, no bundler, no JS framework - opens in a browser directly via file://
Each variant explores a different direction from intake

Step 5 - Write README.md

Write .design/sketches/<slug>/README.md with:

Topic + one-line summary
List of variants: variant-1.html - direction label - one-line description
How to view: "Open each variant-*.html in a browser."
Next step: "Run {{command_prefix}}sketch-wrap-up <slug> when ready to pick a winner."

After writing


━━━ Sketches created ━━━
Slug: <slug>
Directory: .design/sketches/<slug>/
Variants: N standalone HTML files
Open variant-*.html in a browser.
Next: {{command_prefix}}sketch-wrap-up <slug>
━━━━━━━━━━━━━━━━━━━━━━━━

Do Not

Do not write to src/ - sketches live in .design/sketches/ only.
Do not use build-step syntax (JSX, TS, imports). Standalone HTML only.
Do not overwrite an existing sketch slug without asking.

Frequently asked questions

What does the Gdd Sketch AI skill do?

Why use Gdd Sketch on TypingMind?

Because you install it once and use it with any model. Gdd Sketch 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 Gdd Sketch in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/hegemonart/get-design-done/tree/main/scripts/skill-templates/sketch. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Gdd Sketch?

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 Gdd Sketch?

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

Is the Gdd Sketch AI skill free?

Yes. It is published on GitHub by hegemonart 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.
