Creating a Claude Cowork plugin involves a structured five-phase workflow: Discovery, Component Planning, Design & Clarifying Questions, Implementation, and Review & Package. This process operates within cowork sessions to output a ready-to-install plugin scaffold.

Cowork plugin development follows five phases: Discovery, Component Planning, Design & Clarifying Questions, Implementation, and Review & Package. Each phase enforces governance and alignment to ensure scope and requirements are captured upfront before final packaging.

Yes, you can build cowork plugins in multi-user sessions using collaborative scaffolding. This supports teams creating a coherent plugin plan and artifacts together, ensuring goals, scope, and outcomes are aligned throughout the guided creation process.

You package a cowork plugin during the Review & Package phase of the creation workflow. This final step reviews the implementation and delivers a complete plugin scaffold that is ready to install and deploy directly from the cowork session.

You do not need to define plugin architecture upfront; the workflow handles this during the Component Planning phase. It guides you through capturing requirements and scope first, then scaffolding the architecture before implementation begins.
