Claude Code Marketplace

Claude Code Plugins Marketplace by @alberduris.

This git repository is a Claude Code Marketplace; in other words, a way to distribute a collection of Plugins that augment Claude Code's capabilities via Commands, Skills, Agents, or Hooks.

Quick Understanding

Zero-bullshit definitions without AI slop so we all know what we're talking about.

Marketplace: A git repository with a .claude-plugin/marketplace.json file listing available Plugins.

Plugin: A packaged directory containing one or more of the following, plus .claude-plugin/plugin.json with metadata (name, version, author):

• Skill: Directory with SKILL.md + supporting files (scripts, templates, docs).
• Command: Single .md file.
• Agent: Isolated autonomous agent launched via Task tool; runs multi-turn conversation with tools (agent ↔ tools), returns final result. (Learn more)
• Hook: Script triggered by events (file edits, tool calls, user prompt submission).

Invocation: Both Skills and Commands can be invoked 3 ways: manually (/name), by Claude via Skill tool, or auto-discovered by context. The only difference is structure. Use disable-model-invocation: true in frontmatter if you want manual-only.
