Stocks Skill

Read-only market data via Yahoo Finance. Five commands: quote, search, history, compare, crypto. Python stdlib only — no API key, no pip installs. Yahoo's endpoint is unofficial and may rate-limit or change.

When to Use

• User asks for a current stock price (AAPL, TSLA, MSFT, ...)
• User wants to look up a ticker by company name
• User wants OHLCV history or performance over a date range
• User wants to compare several tickers side by side
• User asks for a crypto price (BTC, ETH, SOL, ...)

Prerequisites

Python 3.8+ stdlib only. Optional: set ALPHA_VANTAGE_KEY to enrich market_cap, pe_ratio, and 52-week levels when Yahoo's crumb-protected fields come back null. Free key: https://www.alphavantage.co/support/#api-key
