install.sh

#!/usr/bin/env bash
# Symlink a skill from this repo into the user-level skill directories of
# Claude Code (~/.claude/skills) and OpenAI Codex (~/.agents/skills).
#
# Usage:
#   ./install.sh [--claude|--codex] <skill-name>   install one skill
#   ./install.sh [--claude|--codex] --all          install every skill under skills/
#   ./install.sh --list                            list available skills
#
# By default skills are linked for both tools. Use --claude or --codex to
# target one (e.g. if Claude Code already gets the skills via the plugin
# marketplace, use --codex to avoid duplicates).
