# plugin-refresh.sh  -  bring the stack plugins to the latest published version.
#
# Two steps, because they are two different things: `claude plugin marketplace
# update` refreshes the catalog, and each installed plugin then needs its own
# `claude plugin update` in the scope it was installed in. A project or local
# install is updated from inside its own project, because that is how the CLI
# tells two projects' installs apart. The catalog refresh alone leaves every
# installed plugin where it was.
#
# Usage: plugin-refresh.sh <owner> [--add-only]
#   <owner>      GitHub owner of the multi-agent-plugins repository
#   --add-only   make sure the marketplace is configured, update nothing
#
# The CLI's own error output is passed through, never discarded.
# Exit codes: 0 = done (or no claude CLI on this machine), 1 = a step failed
