Includes 12+ working examples, 6 production-ready validation scripts, and approximately 21,000 words of documentation.
The toolkit emphasizes security-first development, portable configurations using environment variables, and progressive disclosure patterns that balance context efficiency with comprehensive guidance when needed.
How to use: Run /plugin-dev:create-plugin to start an 8-phase guided workflow that walks you through discovery, planning, design, implementation, validation, testing, and documentation. Ask questions like "how do I create a PreToolUse hook?", "how do I set up an MCP server?", or "what's the best plugin structure?" to load the relevant skill automatically.
