alpaca
This skill is a CLI for trading via Alpaca: it uses `ALPACA_API_KEY`, `ALPACA_SECRET_KEY`, and `ALPACA_PAPER`, reads/writes `~/.openclaw/credentials/alpaca.json` and `~/.openclaw/data/alpaca-alerts.json`, and provides `python3 scripts/alpaca_cli.py` commands. It makes network calls to `https://api.alpaca.markets` and streaming endpoints.
