# lucerna-crew 0.5.1 — the crew board in your terminal and in Claude Code.
#
# Read this before you run it. In order, it:
#   1. checks for Node.js 20.3 or newer, and curl;
#   2. downloads the 27 files listed near the bottom from
#      https://lucernanoetica.com/crew/files/ into a temporary folder, and checks each one's
#      sha256 against that list. A mismatch means a download arrived broken,
#      and nothing is installed;
#   3. moves them to ~/.local/share/lucerna-crew/0.5.1 (XDG_DATA_HOME is honoured);
#   4. if Claude Code is installed, adds that folder as the "lucerna" plugin
#      marketplace and installs the lucerna-crew plugin;
#   5. runs "lucerna-crew install": a two-line lucerna-crew in ~/.local/bin, the
#      crew line after your own Claude Code status line (your settings are backed
#      up first), and the plugin switched on for your user. It joins no board and
#      says nothing in any session until you run /lucerna-crew:join in it.
# It never asks for a password, never reads a key, and changes nothing else.
# Signing in is a separate step you run yourself: lucerna-crew login.
