Claude Code authoring tools: create plugins, skills, commands, and introspect Claude Code internals
npx claudepluginhub lttr/claude-marketplace --plugin ccShow recent Claude Code changes personalized to user's setup. Trigger when user asks about changelog, "what's new", "cc changelog", "claude code updates", "recent changes", or wants to know what changed in Claude Code.
This skill should be used when creating, modifying, or managing Claude Code plugins and plugin marketplaces. Trigger when working with plugin manifests (plugin.json, marketplace.json), creating plugin directory structures, adding plugin components (commands, skills, agents, hooks), version bumping, or when discussing plugin development workflows.
Guide for creating and editing Claude Code skills. Use when user wants to create a new skill, update an existing skill, or needs help structuring a SKILL.md file.
