commodities

Fetch commodity prices for WTI (Crude Oil), Brent, Natural Gas, and Gold using Yahoo Finance (yfinance). Follow the same pattern as stock-price-checker-pro.

Security Scan

The skill's code, runtime instructions, and requirements are coherent with its stated purpose of fetching commodity prices via yfinance; it requests no unexpected credentials or system access.

Purpose & Capability

Name/description match the included Python scripts which use yfinance to fetch commodity tickers; the declared required binary (uv) is consistent with the SKILL.md commands.

Instruction Scope

SKILL.md and the code limit behavior to calling yfinance for price/history/news and formatting output. The skill does not read unrelated files or environment variables. It does surface news article link URLs (from Yahoo) but does not follow or fetch them itself.

Install Mechanism

There is no external download URL; main.py contains an inline dependency block that causes uv to install the 'yfinance' Python package (likely via PyPI) at runtime. Installing a package from PyPI is normal here but is the primary runtime install action to be aware of.

Credentials

The skill requests no env vars, no credentials, and no config paths. All external access is to Yahoo Finance via the yfinance library, which is appropriate for the stated function.

Persistence & Privilege

always is false and the skill does not claim or attempt to persist beyond its own files. Autonomous invocation is allowed (platform default) but not combined with any elevated privileges or secret access.

Assessment

This skill appears to do only what it says: run a small Python script (via the uv runner) that installs yfinance and queries Yahoo Finance for commodity tickers. Before installing, ensure you have (or trust) the 'uv' runner since it will install yfinance from PyPI at runtime and perform network requests to Yahoo. No API keys or secrets are requested. If you have security concerns, review the included source files yourself or run the skill in an isolated environment (container/VM) to limit exposure.

Skill: Commodities

When to use

• The user asks for current commodity prices (WTI, Brent, Natural Gas, Gold).
• The user wants daily change, percent change, recent high/low ranges, or recent headlines affecting these commodities.

When NOT to use

• User wants equities, fundamentals, or portfolio-level analysis — use the stock skills instead.

Authentication

• No API key required. Uses Yahoo Finance via yfinance.

Commands

Check a commodity price

uv run skills/commodities/src/main.py <SYMBOL>

Examples

uv run skills/commodities/src/main.py CL=F   # WTI Crude Futures (WTI)
uv run skills/commodities/src/main.py BZ=F   # Brent Crude Futures (Brent)
uv run skills/commodities/src/main.py NG=F   # Natural Gas Futures (NG)
uv run skills/commodities/src/main.py GC=F   # Gold Futures (GC)

Ticker Reference (Yahoo Finance)

Commodity	Yahoo Ticker
WTI Crude Oil	CL=F
Brent Crude	BZ=F
Natural Gas	NG=F
Gold Futures	GC=F

Output

• Current price, daily change & % change
• Previous close
• Today's high / low
• 2W, 1M, 3M, 6M, 52W high / low ranges
• Recent headlines (when available)

Notes

• uv run reads the inline # /// script dependency block in main.py and auto-installs yfinance.
• Do NOT use web search or curl for these prices — use this script for consistent formatting.
