This skill should be used when the user asks to "create a Knockout.js component", "add a UI Component", "modify layout XML", "customize a template", "write LESS CSS", "style with the Magento UI library", "add a RequireJS module", "extend JavaScript", "customize checkout", or "modify the cart page". Covers Magento 2 frontend development using the Luma/Blank theme. DEPENDENT on magento2-dev-core for backend patterns and escaping.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Magento 2 Frontend Developer This skill covers Luma/Blank theme development, Knockout.js, RequireJS, LESS CSS, and UI Components. ## Related Skills **REQUIRED BACKGROUND:** Load `magento2-dev-core` first — it defines the escaping (`escapeHtml`/`escapeHtmlAttr`/`escapeJs`) and backend patterns this skill's templates and view models rely on. This skill targets Luma/Blank-derived themes. If the project's `theme.xml` parent is `Hyva/default` or `Hyva/reset` (or `composer.json` requires `hyva-themes/*`), use `magento2-hyva-dev` instead — the two frontend stacks are mutually exclusive and share almost no code patterns. Hybrid projects (e.g. dual-stack) keep both: `app/design/frontend/<Vendor>/luma_child` → this skill, `app/design/frontend/<Vendor>/hyva_*` → `magento2-hyva-dev` (check both `theme.xml` parent **and** `composer.json` `hyva-themes/*` before assuming either applies). ## Theme Structure ``` app/design/frontend/Vendor/Theme/ ├── registration.php ├── theme.xml ├── composer.json ├── media/ │ └── preview.jpg ├── web/ │ ├── css/ │ │ └── source/ │ │ ├── _extend.less │ │ ├── _theme.less │ │ └── _variables.less │ ├── js/ …

How to install
mdr add ddtcorex/maestro-skills/magento2-frontend-dev@sha256:84d9a0ec3ea02fa9The line at the top of this page pins the label git:20261005.6d59fc7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
