Plugin Development for Claude Code & OpenCode

About

This skill provides a systematic framework for architecting, building, and maintaining extensions for Claude Code and OpenCode using the ai-eng-system. It enables developers to create canonical content for commands, agents, and skills that are automatically transformed into platform-specific formats. By emphasizing structured development and iterative testing, it ensures that custom AI tools are robust, maintainable, and seamlessly integrated into developer workflows across both platforms.
