# Yo Human — Cowork one-line installer.
# Meant to be run BY Claude Cowork on the user's Mac (it's agentic), e.g. the onboarding page
# tells the user to paste:  "Install Yo Human by running:
#   curl -fsSL https://yohuman.ai/cowork-install.sh | YH_CHANNEL='yohuman-cw-xxxx' bash"
# It places the Yo Human plug-in and registers it in the Claude Desktop app, wired to the
# user's private channel. No JSON editing, no jq — the JSON merge is done with node (already
# required for the plug-in). Existing Claude settings are backed up and preserved.
