# Two rules, both learned the hard way:
#
# 1. These are `elif`, not four sequential `if`s. As separate ifs the LAST
#    match won, so a stray ~/.codex silently overrode a correctly detected
#    Claude Code project and the skill landed somewhere the agent never reads.
#
# 2. INSTALL_DIR is NEVER the user's project root. It used to be `$(pwd)` when
#    a .claude directory was present, and the clone-or-update branch below then
#    ran `git pull --ff-only` INSIDE THE USER'S OWN REPOSITORY against an
#    unrelated remote — or, on the clone path, aborted the script under `set -e`
#    because the directory was not empty. Both outcomes are wrong and one of
#    them touches work that is not ours.
