Alpaca Trading

This lets Claude execute stock trades and manage portfolios through Alpaca's Trading API using the apcacli command-line tool. You can buy and sell stocks, ETFs, options, and crypto, check positions and account balances, set stop losses, and monitor real-time trade updates. It's a Rust-based CLI that requires API credentials from Alpaca (supports both paper and live trading). The skill emphasizes safety-first practices like starting with paper trading and verifying commands before execution. Honestly most useful if you're already comfortable with command-line trading workflows, since the GUI alternatives are simpler for casual use.
