plugin-dev is a Claude Code plugin that provides a toolkit for developing other Claude Code plugins. It bundles seven specialized skills covering hooks, MCP integration, plugin structure, plugin settings, command development, agent development, and skill development, per the README. It also includes a guided 8-phase workflow command, /plugin-dev:create-plugin, for building plugins from scratch. Each skill follows a progressive disclosure pattern with core SKILL.md documentation, reference docs, examples, and utility scripts. The README lists total content of roughly 11,065 words of core skill documentation, 10,000+ words of reference docs, 12+ working examples, and 6 validation/testing/parsing utility scripts.
