12ui Design

Public, installable distribution of the 12ui design skill and its API contracts. The hosted service and documentation live at 12ui.com.

This repository is generated from the private 12ui implementation at the exact @12ui/design release revision. Version 0.2.27 matches the npm package.

Install

The cross-agent installer supports Codex, Claude Code, Grok, Cursor, Antigravity, and GitHub Copilot:

npx -y @12ui/design skill install

For Codex plugin distribution through the Just Every marketplace:

codex plugin marketplace add just-every/plugins
codex plugin add 12ui-design@just-every

Skill directories may also index or install the individual folders under skills/. Each skill includes the one-time CLI and account setup command needed by a directory-only install.

Skills

• design — explore, choose, expand, convert, and integrate a distinctive interface.

Public API contracts

• convert-v1.openapi.yaml
• create-v1.openapi.yaml
• corpus-v1.openapi.yaml
• CONVERSION_PACKAGES.md
• EXPORT_FORMATS.md

The skills use the public https://12ui.com API. Authentication is established by the installer and stored locally; credentials are never included in this repository.

Provenance

Every release is generated from a fixed allowlist, validated for exact skill and contract parity, tagged design-v0.2.27, and published only after the matching npm release completes. Do not edit generated files directly; changes must originate in the 12ui release source.
