For Plugin Developers

Automatic Version Management

The versions.json file is automatically generated from each plugin's plugin.json file. You don't need to manually maintain it.

Local Generation

To regenerate versions.json locally:

bash scripts/generate-versions.sh

Automatic Updates via GitHub Actions

When you push changes to any plugins/*/.claude-plugin/plugin.json file, GitHub Actions will automatically:

1. Run the generation script
2. Update versions.json
3. Commit and push the changes

You can also manually trigger the workflow from the GitHub Actions tab.

Publishing a New Version

1. Update the version in your plugin's .claude-plugin/plugin.json:

   {
     "name": "your-plugin",
     "version": "1.1.0",
     ...
   }
   

2. Update the plugin's CHANGELOG.md with the new version details

3. Commit and push:

   git add plugins/your-plugin/.claude-plugin/plugin.json
   git add plugins/your-plugin/CHANGELOG.md
   git commit -m "chore: bump your-plugin to v1.1.0"
   git push
   

4. GitHub Actions will automatically update versions.json
