Installation

The plugin needs two things on the machine: the barrierlab binary, which does the audit, and python3 (3.9 or newer, standard library only), which builds the frame of the report.

The engine

barrierlab-cli is installed from its repository and needs Rust 1.88 or newer:

cargo install --git https://github.com/casoon/barrierlab-cli

The plugin

Inside Claude Code, add the marketplace and install the plugin from it:

/plugin marketplace add casoon/barrierlab-agent-plugin
/plugin install barrierlab@barrierlab

Check the setup

/barrierlab:doctor

The command changes nothing. It reports one line per check and, for anything missing, the command that fixes it. What it checks is listed under Commands.
