stock-price-checker

Check stock prices using yfinance library. No API key required.

Security Scan

The skill's code, instructions, and requirements are consistent with its stated purpose (fetching stock data via yfinance); there are no requests for secrets or suspicious network endpoints.

Purpose & Capability

Name, description, SKILL.md, and the Python code all match: they fetch stock data using the yfinance library. Required binaries (python3 and yfinance) are proportional and expected.

Instruction Scope

Runtime instructions are limited to running the included Python script and do not attempt to read unrelated files or environment variables. Minor inconsistency: the included stock-price.sh references an absolute path (/home/clawdbot/...), which is environment-specific and may fail or behave unexpectedly if the skill is installed elsewhere; it does not appear malicious but is sloppy.

Install Mechanism

No install spec (instruction-only) and bundled code only; nothing is downloaded or written during install. This is the lowest-risk install pattern.

Credentials

The skill requests no environment variables or credentials. Access to network via yfinance is required for its stated function; no secret exfiltration mechanisms are present in the code.

Persistence & Privilege

always is false and the skill does not modify other skills or system-wide settings. It does not request elevated or persistent privileges.

Assessment

This skill appears to do what it claims: run the Python script to fetch stock data via yfinance. Before installing or running it, (1) ensure you have yfinance installed in a trusted Python environment, (2) be aware the script makes network requests to Yahoo Finance (expected for this function), and (3) inspect or remove the stock-price.sh wrapper because it hardcodes an absolute path (/home/clawdbot/...) that may fail or be inappropriate for your environment. No credentials are requested.

Get current stock prices from Yahoo Finance using the yfinance library.
