# OrderBee skill installer — cross-agent.
# Installs the OrderBee skill (SKILL.md + helper + API reference) into any
# SKILL.md-compatible agent: Claude Code, Codex, Copilot CLI, Gemini CLI,
# OpenClaw, Hermes. Other SKILL.md agents (Pi, Antigravity, Claude apps) load
# skills their own way — install with --dir into their skills directory.
#
# Usage:
#   curl -fsSL https://orderbee.app/install.sh | sh
#   curl -fsSL https://orderbee.app/install.sh | sh -s -- --agent codex
#   curl -fsSL https://orderbee.app/install.sh | sh -s -- --dir ~/somewhere/skills
#
# With no flags it installs into every supported agent whose config dir exists.

Done. Set your environment (or let the skill self-signup on first run):
  export ORDERBEE_BASE_URL=$BASE_URL_DEFAULT
  export ORDERBEE_API_KEY=...   # get a key at $BASE_URL_DEFAULT

Then ask your agent to order from a local business.
