What problem does it solve? Manually installing a local Claude Code plugin involves copying files, editing marketplace.json, running validation, and registering the plugin, which is error-prone and easy to get wrong. This Skill automates the entire installation pipeline so a local plugin folder becomes an active, registered plugin in one step. ## Core Features & Use Cases - One-command installation: Copies the plugin into the personal marketplace, merges the marketplace registry entry, validates, registers, and installs or updates the plugin via a single script. - Pre-install validation: Runs offline structural validation first, reports problems, and handles plugins with or without a .claude-plugin/plugin.json manifest. - Registry safety: Preserves existing entries in marketplace.json and aligns with an existing marketplace via --marketplace-root and --marketplace-name instead of creating duplicates. - Use Case: You finished building a plugin in a local folder and want it live in Claude Code. Point this Skill at the folder and it validates, installs, and confirms the plugin appears as <plugin-id>@personal in claude plugin list. ## Quick Start Install the plugin folder at ~/projects/my-plugin into my personal Claude Code marketplace and confirm it is active.
