Technical Notes
- Uses yfinance library to fetch data from Yahoo Finance
- No API key required
- Handles errors gracefully
- Works with most major stocks and ETFs
- Returns comprehensive data including market cap, volume, and 52-week range
Troubleshooting
- If the stock symbol is invalid, the script will return an error
- Some data (like market cap) may not be available for all symbols
Usage Guidance
This appears safe for checking public stock and ETF prices. Before use, make sure the yfinance dependency is installed from a trusted source, and remember that ticker lookups are handled by Yahoo Finance through the yfinance library.
Capability Analysis
Type: OpenClaw Skill
Name: stock-price-checker
Version: 1.0.0
The skill bundle is a straightforward stock price checker using the `yfinance` library. The `SKILL.md` provides clear instructions without any prompt injection attempts. The `stock-price.sh` script is a simple wrapper executing the Python script. The `stock-price.py` script uses the legitimate `yfinance` library to fetch public stock data and does not exhibit any signs of data exfiltration, malicious execution, persistence, or obfuscation. All actions are aligned with the stated purpose.
Capability Assessment
Purpose & Capability
The SKILL.md describes checking stock prices, and the Python code accepts a stock symbol, queries yfinance, and formats market data.
Instruction Scope
The runtime instructions are user-directed command examples for checking specific tickers; they do not instruct autonomous bulk actions or hidden behavior.
Install Mechanism
There is no install spec, but the skill depends on an external yfinance Python package being present; users should ensure that dependency comes from a trusted source.
Credentials
No API keys, environment variables, config paths, or local file access are requested. The external Yahoo Finance data flow is disclosed and proportional to the purpose.
Persistence & Privilege
The artifacts show no persistence, background service, privilege escalation, file mutation, or credential/session use.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install stock-price-checker - After installation, invoke the skill by name or use
/stock-price-checker - Provide required inputs per the skill's parameter spec and get structured output
