What are event hooks in Claude Code?

Event hooks are triggers that allow your plugin to execute scripts or commands at specific points, such as before a tool is used (PreToolUse) or after a prompt is submitted.

What is required to start a Claude Code plugin?

Every Claude Code plugin requires a plugin.json file containing the plugin's name, version, and description, housed within a dedicated project directory.

Can I integrate MCP servers with this skill?

Yes, this skill provides the structure to configure MCP (Model Context Protocol) servers directly within the plugin.json, including command arguments and environment variables.

How do I test my plugin locally?

You can test locally by using the '/plugin marketplace add' command with the path to your local directory, followed by '/plugin install' to activate it in your environment.

How do I add custom commands to Claude Code?

You can define custom slash commands by creating markdown files within a 'commands/' directory. Each file includes frontmatter for the description and the prompt logic to be executed.
