# Hermes Bridge — remote bootstrap installer.
#
# The one-liner behind https://get.agentfy.app :
#
#     curl -fsSL https://get.agentfy.app | bash
#
# Clones (or updates) the Hermes Bridge repo, then runs install.sh, which
# installs the bridge into the same Python environment that runs Hermes Agent.
# Safe to re-run (idempotent).
#
# Overrides (env vars):
#   BRIDGE_REPO   git URL to clone           (default: jcnh74/hermes-bridge)
#   BRIDGE_REF    branch/tag/commit          (default: main)
#   BRIDGE_DIR    where to clone             (default: ~/.hermes/hermes-bridge-src)
