How can I ensure my plugin follows best practices?

The toolkit includes built-in agents like 'plugin-validator' and 'skill-reviewer' to automatically audit your code, structure, and trigger phrases for quality.

How do I create an autonomous subagent?

The guide includes an 'agent-development' workflow that teaches you how to write system prompts, configure triggers, and restrict tool access for specialized sub-tasks.

What is a Claude Code plugin?

A plugin is a packaged set of capabilities—including commands, skills, agents, and hooks—that extend Claude's functionality and domain knowledge within the terminal environment.

Can I integrate external APIs with Claude Code?

Yes, this guide provides specialized instructions for MCP (Model Context Protocol) integration, allowing your plugins to communicate with external services and data sources.

How do I start building a new plugin?
