# Installs into ~/.claude/skills/clip/ — that folder name (clip) is what
# registers the bare /clip command. It ships as a standalone skill, NOT a
# plugin, on purpose: a plugin would always namespace the command as
# /clip:clip. Same reasoning as claude-code-queue; see that repo's CLAUDE.md.
#
# Also symlinks the CLI to ~/.local/bin/clip so `clip <path>` works in any
# terminal. Both halves are the same script — one capability, two front doors.
#
# Re-running updates in place. To uninstall:
#   rm -rf ~/.claude/skills/clip ~/.local/bin/clip
