/plugin install dev-docs@claudesmith-marketplace
claude plugin validate .
Each plugin lives under plugins/<category>/<name>/ with a manifest at .claude-plugin/plugin.json and component directories at the plugin root (not inside .claude-plugin/).
Minimal manifest example:
{
"name": "my-plugin",
"version": "0.1.0",
"description": "What this plugin does",
"author": { "name": "Your Name" },
"license": "MIT",
"keywords": ["team", "feature"]
}
After adding files, run node scripts/generate-marketplace.js to refresh marketplace.json.
