# Hermes Workspace — one-liner installer
#
# Usage:
#   curl -fsSL https://raw.githubusercontent.com/outsourc-e/hermes-workspace/main/install.sh | bash
#
# What it does:
#   1. Verifies Node 22+, git, pnpm
#   2. Installs hermes-agent via Nous's official upstream installer
#   3. Clones hermes-workspace
#   4. Sets up .env, enables the Hermes API server, installs deps,
#      and links bundled skills
#
# Re-runnable. Will skip anything already installed.

Next steps (two terminals):

  1) Start the Hermes Agent gateway:
       hermes gateway run
     (first run may prompt for hermes setup)

  2) Start the workspace UI:
       cd $INSTALL_DIR && pnpm dev

  3) Open http://localhost:${WORKSPACE_PORT}

If the gateway was already running before this install,
restart it so API_SERVER_ENABLED=true takes effect.
