What is a Claude Code plugin?

A Claude Code plugin is a specialized package containing skills, commands, and configurations that enhance Claude's ability to perform domain-specific tasks and follow best practices.

How do I ensure my plugin is discoverable?

Effective discoverability depends on using kebab-case naming, providing a clear description in plugin.json, and correctly registering the source in your marketplace.json file.

How do I handle versioning for my Claude plugins?

Plugins should follow Semantic Versioning (SemVer), where patch updates are for fixes, minor updates for new features, and major updates for breaking changes.

Can I test my custom plugin locally before publishing?

Yes, you can install plugins locally using the /plugin install command with a relative path to your local marketplace directory to verify behavior and command invocation.

What is the recommended format for SKILL.md?

The Plugin Builder recommends a progressive disclosure format, starting with purpose and prerequisites, followed by step-by-step instructions, concrete examples, and common troubleshooting tips.
