Use when migrating a project from Tailwind v3 to v4, mapping @theme namespaces to generated utilities, or looking up renamed/removed v3 utilities.
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
<objective> Documents Tailwind CSS v4 (current stable v4.3) core features relevant to a v3→v4 migration: the `@theme` namespace-to-generated-utility mapping (`--color-*`→`bg-*`/`text-*`, `--spacing-*`→`p-*`/`m-*`/`gap-*`, etc.), the v3→v4 breaking changes (removed `@tailwind` directives, renamed utilities like `shadow-sm`→`shadow-xs`, removed `bg-opacity-*`/`flex-shrink-*`, the `@utility` custom-utility syntax change, arbitrary-value variable syntax, important-modifier position), and the `@tailwindcss/upgrade` CLI tool. Not the day-to-day CSS-first configuration reference (`tailwindcss-core` owns `@theme`/`@utility`/`@variant` usage) and not a utility-class lookup (the category skills own that). </objective> # Tailwind CSS v4.3 Core Current stable: `tailwindcss` 4.3.3 (July 2026). Minor releases since v4.0: v4.1 (text shadows, masks), v4.2 (mauve/olive/mist/taupe palettes, `@tailwindcss/webpack`, logical `pbs`/`mbs`/`inline-*`/`block-*`/`inset-s|e|bs|be` utilities, `font-features-*`; `start-*`/`end-*` deprecated), v4.3 (scrollbar utilities, `@container-size`, `zoom-*`, `tab-*`, stacked/compound `@variant`, `--default()` in functional `@utility`). ## Documentation …

How to install
mdr add fusengine/agents/tailwindcss-v4@sha256:e52cc20b1ff61e7cThe line at the top of this page pins the label git:20260927.43a351c, 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.
