# Install Claude Code plugins from brain manifest
# Adds marketplaces, installs plugins, warns on SHA mismatch.
#
# CORRECTION B: real Claude CLI subcommand shape is
#   `claude plugin marketplace add <repo>`  (NOT `claude marketplace add`)
#   `claude plugin marketplace list`
#   `claude plugin install <name@marketplace>`
#   `claude plugin info <name@marketplace> --json`
# Phase 0 discovery confirmed: `marketplace` is a child of `plugin`, not a
# top-level subcommand. The plan originally had the wrong shape.
#
# Usage: install-plugins.sh --marketplaces=<path> --manifest=<path>
