Installation

npx skills add https://github.com/gracefullight/stock-checker --skill yahoo-finance

Summary

Get stock prices, quotes, fundamentals, earnings, options, dividends, and analyst ratings using Yahoo Finance. Uses yfinance library - no API key required.

SKILL.md

Yahoo Finance CLI

A Python CLI for fetching comprehensive stock data from Yahoo Finance using yfinance.

Requirements

  • Python 3.11+
  • uv (for inline script dependencies)

Installing uv

The script requires uv - an extremely fast Python package manager. Check if it's installed:

uv --version

If not installed, install it using one of these methods:

macOS / Linux

curl -LsSf https://astral.sh/uv/install.sh | sh

macOS (Homebrew)

brew install uv

Windows

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

pip (any platform)

pip install uv

After installation, restart your terminal or run:

source ~/.bashrc  # or ~/.zshrc on macOS

Installation

The yf script uses PEP 723 inline script metadata - dependencies are auto-installed on first run.

# Make executable
chmod +x /path/to/skills/yahoo-finance/yf

# Optionally symlink to PATH for global access
ln -sf /path/to/skills/yahoo-finance/yf /usr/local/bin/yf

First run will install dependencies (yfinance, rich) to uv's cache. Subsequent runs are instant.

Commands

Price (quick check)

yf AAPL              # shorthand for price
yf price AAPL

yf quote MSFT

Troubleshooting

"command not found: uv"

Install uv using the instructions above.

Rate limiting / connection errors

Yahoo Finance may rate limit excessive requests. Wait a few minutes and try again.

"No data" for a symbol

  • Verify the symbol exists: yf search "company name"
  • Some data (options, dividends) isn't available for all securities

Technical Notes

  • Uses PEP 723 inline script metadata for uv dependencies
  • Rich library provides colored, formatted tables
  • First run installs deps to uv cache (~5 seconds)
  • Subsequent runs are instant (cached environment)
  • Handles NaN/None values gracefully with fallbacks
