What problem does it solve? Creating plugins for Claude Code and Cowork involves many subtle rules — manifest placement, hook auto-discovery, path portability, sandbox constraints — and violating any of them causes silent, hard-to-debug failures. This Skill guides the full plugin lifecycle so plugins load, trigger, and distribute correctly. ## Core Features & Use Cases - End-to-end plugin workflow: Six phases covering planning, scaffolding, component building (skills, commands, hooks, agents, MCP), local testing, debugging, and distribution via marketplace, GitHub, or npm. - Component specifications: Detailed references for SKILL.md frontmatter rules, command syntax, hook events, MCP transports, and agent definitions, plus Cowork-specific sandbox and connector guidance. - Debugging and validation: Systematic fixes for common failures (skills not triggering, duplicate hooks, hardcoded paths) plus a pre-release validation checklist. - Use Case: You have a standalone skill in ~/.claude/skills/ and want to ship it to your team on Cowork — this Skill walks you through porting it, adapting language for non-developers, packaging as a .plugin file, and publishing. ## Quick Start Ask Claude to scaffold a new plugin with one skill for your chosen workflow, then follow the guided phases to test, debug, and distribute it.
