Use Bash to check EXTEND.md existence (priority order):
# Check project-level first
test -f .canghe-skills/canghe-compress-image/EXTEND.md && echo "project"
# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.canghe-skills/canghe-compress-image/EXTEND.md" && echo "user"
