Plugins in Claude Code + Claude Code Notes | Final Video | CampusX

This video concludes the Claude Code playlist by exploring one of the most powerful concepts in agentic coding: Plugins. The video explains how plugins package skills, hooks, slash commands, MCP tools, and subagents into reusable workflows that teams can easily share and install through marketplaces. Along with the theory, the video also completes the Spendly expense tracker project, adds the final delete-expense feature, and deploys the Flask application using the Railway plugin inside Claude Code.
