What is Struq?

Struq is a free, open-source design skill for Claude Code, Cursor, Codex and other AI coding tools: your AI settles the direction, type, colour and motion before it builds, so your site looks studio-made, not AI-made.

What is it made of?

Four parts. The skill is the centre; the icons, the photos and the MCP are what it reaches for.

The Struq skillFree and open source. Your agent settles a direction, two typefaces, a colour system and the motion, stops once for your approval, then builds from 44 admitted blocks and checks its own work.Struq Icons182 two-tone icons under the MIT licence, 118 of them with one small move on hover. Every build uses them by default.The photo libraryArt-directed CC0 packs. The skill picks from them for every photo slot your own images do not fill.The Struq MCPA server that hands your agent the catalogue live: the direction for a brief, the blocks as real files and the check. Its four catalogue tools are free, with a free account.

What it holds to.

Four rules, kept in every release of the skill, the icons and the MCP.

No design scores.

The check returns what fails and how to fix it. A number out of ten tells you nothing to change, so Struq never gives one.

The photos are CC0.

Every photo in the library is free to use, in your work and your clients’, with no credit owed.

The skill is free.

Open source under the MIT licence, with no account, no key and nothing to configure. You pay only for your own AI tool.

Nothing is invented.

The skill never writes a testimonial, a client or a number you did not supply. Where a site is a demonstration, a caption says so.

Where does it live?

In the open. The source is on GitHub, the packages are on npm, and this site is its one home.

github.com/struqappThe organisation. The skill’s source, its README and its changelog live in struq-design.@struq/skillThe skill. npx @struq/skill@latest installs it into every AI tool on your machine.@struq/iconsThe icons. npm install @struq/icons adds them to any project, with or without the skill.struq.appThis site, and the Struq MCP at https://struq.app/api/mcp.
