How to use the Wireframe Sketch agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
Wireframe Sketch is an agent skill that tells an AI agent to build a rough, hand-drawn looking wireframe as a single web page. It is aimed at early design work, when you want to test layout ideas quickly without the output looking finished. This guide explains what an agent skill is, how to install this one, how to ask for a sketch, and where it fits and where it does not.
Wireframe Sketchnexu-io/html-anything · Apache-2.0 Download the skill Quick start
- 1Get the ZIP. Download the wireframe-sketch ZIP from the page where you found this guide.
- 2Unzip the folder. Extract it so the wireframe-sketch folder contains SKILL.md and example.html.
- 3Place it where the agent can find it. Copy the folder to ~/.claude/skills/ for personal use, or to a project's .claude/skills/ folder for one project.
- 4Or upload in the Claude apps. In the Claude apps, go to Settings → Capabilities → Skills and upload the ZIP.
- 5Preview the example. Open example.html in a browser to see the intended sketch look.
- 6Ask for a sketch. Describe the screen, its content blocks and any variants, and ask for a rough hand-drawn style wireframe.
- 7Review and iterate. Use the sticky-note annotations and tabs as discussion points, then ask for changes to content or layout.
What is an agent skill, and what does Wireframe Sketch make the agent do?
An agent skill is a folder containing a SKILL.md instruction file (and sometimes other files) that an AI agent can load when a task matches it. The instructions tell the agent how to approach that kind of task.
Wireframe Sketch gives the agent a specific visual style for an early-stage wireframe. The result is a single web page with a graph-paper background, marker-style strokes, scribbled chart placeholders with hatched fills, several tabbed variant labels, and slightly tilted yellow sticky-note annotations. The skill's stated intent is exploration before a whiteboard-to-visual stage, and it deliberately avoids neat alignment.
- Graph-paper background
- Marker-style strokes and hand-lettered fonts (the source names Caveat and Architects Daughter)
- Multiple tab labels for variants
- Scribbled chart placeholders with hatched fills
- Yellow sticky-note annotations, tilted slightly
- Desktop-oriented layout (the source gives a 1440 desktop aspect hint)
Install Wireframe Sketch from the ZIP download
Download the skill as a ZIP from the page where you found this guide. Unzip it so the wireframe-sketch folder (containing SKILL.md and example.html) ends up in one of these locations:
For a personal install available across your projects, use ~/.claude/skills/. For a single project, put it in that project's .claude/skills/ folder. Both locations are described in the source instructions for this kind of skill.
If you use the Claude apps instead, you can upload the ZIP under Settings → Capabilities → Skills.
- Personal: ~/.claude/skills/wireframe-sketch/
- Project only: .claude/skills/wireframe-sketch/ inside your project
- Claude apps: Settings → Capabilities → Skills, then upload the ZIP
How to trigger the skill with a natural request
You do not need a special command. Describe the screen you want and say you want a rough, hand-drawn or sketch-style wireframe, so the agent matches the request to this skill. Mentioning whiteboard, lo-fi, or early exploration also helps, since those words appear in the skill's description and tags.
Be specific about the screen itself: what it is for, what sections it needs, and what variants you want to compare. The skill focuses on the look; the content comes from your request.
- "Sketch a lo-fi wireframe for a meeting-notes app dashboard, with three tab variants."
- "Make a hand-drawn style wireframe of a checkout page on desktop, with sticky-note comments on the pricing block."
- "I'm on a whiteboard stage. Draft a rough sketch-style layout for an onboarding screen with a chart placeholder."
What to expect from the output
The output is meant to look like a rough sketch. Alignment is intentionally loose, and the fonts are hand-lettered styles. Use the included example.html to see the intended look before you ask for your own screen.
Treat the result as a discussion piece. It shows layout and content ideas, not spacing, colour, or interaction decisions you would ship.
- Open example.html in a browser to preview the style
- Expect loose alignment and tilted notes by design
- Expect placeholder charts, not real data
Safety notes: scripts and network access
The skill, as listed, does not run scripts and does not use the network. It has no listed requirements. Its files are SKILL.md and example.html. Because it only shapes how the agent writes a page, you can review SKILL.md and example.html before installing if you want to check what it asks for.
Always check any skill's files before installing it, and keep your own review step for the generated HTML before you share it.
- Runs scripts: no
- Uses network: no
- Requirements: none listed
- Files: SKILL.md, example.html
Tips for better sketches
Give a clear purpose for the screen so the layout has a reason to exist. Ask for named variants if you want to compare directions, since the skill uses tab labels for them. Use sticky-note style annotations to ask the reader questions rather than state final decisions.
If the result looks too polished for your stage, say so and ask the agent to keep the sketch style and loose alignment.
- State the screen's goal and main content blocks
- Request two or three variants to use the tab style
- Ask for sticky notes on the parts you want feedback on
What people use it for
- Testing several layout directions for a dashboard with tab-labelled variants before any visual design work
- Showing stakeholders a rough concept that clearly does not imply a finished design
- Sketching a quick screen idea for a student project or startup pitch in a browser
- Marking up a page with sticky-note questions to gather feedback in a review meeting
Frequently asked questions
How do I install the wireframe-sketch skill?
Download the ZIP from the page, unzip it so the wireframe-sketch folder is present, and place it in ~/.claude/skills/ for personal use or in a project's .claude/skills/ folder. In the Claude apps, you can instead upload the ZIP under Settings → Capabilities → Skills.
Does Wireframe Sketch cost anything or need a licence?
The source lists the licence as Apache-2.0 for the wider html-anything repository, and the skill itself lists no requirements. The source does not give pricing, so check the licence file in the repository for terms.
Does the skill need internet access or run scripts?
According to the listing, it does not run scripts and does not use the network. It includes SKILL.md and example.html.
Can I use Wireframe Sketch for production UI?
No. The skill deliberately avoids neat alignment and does not provide a design system or accessible, pixel-accurate components. Use it for early exploration and a different workflow for production interfaces.
Why does my sketch look messy or unaligned?
That is the intended style. The skill asks for graph-paper backgrounds, tilted sticky notes and loose alignment. If you want a cleaner result, the skill is not the right fit, but you can ask for fewer tilts or fewer annotations within its style.
What are the alternatives to Wireframe Sketch?
The source does not compare this skill with others, so it cannot rank alternatives. If you need polished mockups or a real design system, choose a tool built for high-fidelity UI rather than a sketch-style skill.

Our verdict
Wireframe Sketch suits designers, product teams and students who want fast, rough layout ideas that clearly look unfinished. It is a poor fit for production UI, accessibility-sensitive work or anything that needs a real design system or brand styling.
