#!/usr/bin/env bash
#
# cheat-on-content / uninstall.sh
#
# Removes the 15 cheat-on-content skills from Claude Code and/or Codex skill dirs.
#
# Does NOT touch any content project's data (.cheat-state.json, predictions/,
# rubric_notes.md, candidates.md, etc.) — those live in your content directories
# and uninstalling the skill leaves your work intact.
#
# Usage:
#   bash uninstall.sh          # remove Claude Code install (default)
#   bash uninstall.sh --codex  # remove Codex install
#   bash uninstall.sh --all    # remove both
#
# To re-install: bash install.sh
