Install

The plugin, in Claude Code

The plugin runs its CLI from an npm package that Claude Code installs with it, so node 22 or newer and npm must be on the PATH.

claude plugin marketplace add Mercastra/globu
claude plugin install globu@globu

That gives a session the three skills, the session-start index, the guard and the edit validation. Nothing needs a registered shard: inside one repo the bases work on their own.

The CLI, on its own

The same package works in a terminal without Claude Code, for scripts, CI jobs and checking a base by hand.

npm install -g @mercastra/globu
globu base --help

From source

Clone Mercastra/globu, run npm install and npm run build, then start Claude Code with claude --plugin-dir ./plugins/globu. The development guide covers the quality gates and the release process.
