install.sh

#!/usr/bin/env bash
# Install humanize and ai-check skills for any agent that reads from a skills directory.
#
# Usage:
#   ./install.sh                  # Claude Code     (~/.claude/skills)
#   ./install.sh codex            # Codex CLI       (~/.codex/skills)
#   ./install.sh chatgpt          # ChatGPT agents  (~/.agents/skills)
#   ./install.sh all              # all three of the above
#   ./install.sh --copy           # copy files instead of symlinking
#   ./install.sh all --copy       # combinable with any target
#
# By default the script symlinks the skill directories so that future `git pull`
# updates pick up automatically. Use --copy if you prefer self-contained files.
