What This Skill Does

The stock-price-checker is a specialized OpenClaw agent skill designed to provide real-time financial market data without the friction of managing API keys or paid subscriptions. By leveraging the robust yfinance library, this tool interfaces directly with Yahoo Finance to retrieve accurate, up-to-date information for a vast range of global equities, ETFs, and index trackers. Whether you are tracking the latest performance of tech giants like NVDA or monitoring the stability of broad-market ETFs like VOO, this skill provides a structured, machine-readable output that makes it perfect for both casual market monitoring and integration into larger automated financial workflows.

Installation

To integrate this tool into your OpenClaw environment, use the built-in package manager. Execute the following command in your terminal to download and configure the skill dependencies:

clawhub install openclaw/skills/skills/rupprath/stock-price-checker

Once installed, ensure your Python environment has the necessary dependencies by checking the requirements.txt file located in the skill directory, as it utilizes the standard yfinance package.

Use Cases

This skill is indispensable for users needing quick market intelligence. Ideal use cases include: 1) Portfolio monitoring where quick, ad-hoc price checks are required throughout the trading day. 2) Building automated financial dashboards that require market cap and volume data. 3) Comparing the performance of different ETFs or stocks in real-time. 4) Assisting developers who need to fetch live financial data for testing trading algorithm logic without the overhead of enterprise API providers.

Example Prompts

1. "Check the current market performance and volume for NVDA."
2. "What is the current stock price of Apple (AAPL) and how does its 52-week high compare?"
3. "Can you retrieve the market cap and previous close for VOO and QQQ?"

Tips & Limitations

While highly effective, please note that the tool depends on Yahoo Finance availability. Ensure your internet connection is stable, as the script performs a live web request. If a specific symbol is delisted or entered incorrectly, the script provides error feedback, so ensure tickers are formatted correctly (e.g., use 'BRK-B' for Berkshire Hathaway). Note that financial data can be volatile, and this tool should not be used as the sole basis for high-stakes investment decisions. Always verify critical financial information across multiple sources.
