BUILD YOUR OWN

A plugin is a folder
you can read.

Plugins are standard Claude project skills — a SKILL.md, a few commands, validation logic, reference data. Fork the repo and adapt. Most country plugins are 200–500 lines.

01Fork the repo — every plugin is MIT-licensed
02Swap the reference files for your firm’s policies
03Run it in Claude — writes still go through the governed gateway

Plugins are the procedures. The agents do the volume work, and every write still lands through the same governed gateway — see how it’s governed.
