Installation

Both plugins are distributed through the Claude Code plugin marketplace under the shawn-sandy namespace.

Install both plugins

1. Add the marketplace to your Claude Code session:

   /plugin marketplace add shawn-sandy/agentic-acss-plugins

2. Install acss-kit (components + themes):

   /plugin install acss-kit@shawn-sandy-agentic-acss-plugins

3. Install acss-utilities (atomic CSS + token bridge):

   /plugin install acss-utilities@shawn-sandy-agentic-acss-plugins

4. Verify the install — list available components to confirm acss-kit is active:

   /kit-list

   You should see the full component catalogue grouped by category.

Tip

You can install just one of the plugins if you only need components+themes (acss-kit) or just utility classes (acss-utilities). They’re designed to work together but are independent.

Install only acss-kit

If you don’t need utility classes:

/plugin marketplace add shawn-sandy/agentic-acss-plugins
/plugin install acss-kit@shawn-sandy-agentic-acss-plugins

Install only acss-utilities

If you have an existing component system and just want the utility classes:

/plugin marketplace add shawn-sandy/agentic-acss-plugins
/plugin install acss-utilities@shawn-sandy-agentic-acss-plugins

Note

When using acss-utilities without acss-kit, run /utility-add --no-bridge to skip generating the token bridge (which expects acss-kit theme files).

Verify installation

After installing, confirm the slash commands are available:

/kit-list          # lists all available components
/utility-list      # lists all utility families and classes

Both commands are read-only and make no changes to your project — they’re safe to run at any time to explore what’s available.

Updating the plugins

To get the latest version of a plugin:

/plugin update acss-kit@shawn-sandy-agentic-acss-plugins
/plugin update acss-utilities@shawn-sandy-agentic-acss-plugins

Local development install

If you’ve cloned the plugin repo and want to test local changes without publishing:

# From the acss-plugins repo root
claude --plugin-dir ./plugins/acss-kit

This loads acss-kit directly from the local directory, bypassing the marketplace.
