info

The following is the complete skill definition that Hermes loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.

Stocks Skill

Read-only market data via Yahoo Finance. Five commands: quote, search, history, compare, crypto. Python stdlib only — no API key, no pip installs. Yahoo's endpoint is unofficial and may rate-limit or change.

When to Use

• User asks for a current stock price (AAPL, TSLA, MSFT, ...)
• User wants to look up a ticker by company name
• User wants OHLCV history or performance over a date range
• User wants to compare several tickers side by side
• User asks for a crypto price (BTC, ETH, SOL, ...)

Prerequisites

Python 3.8+ stdlib only. Optional: set ALPHA_VANTAGE_KEY to enrich market_cap, pe_ratio, and 52-week levels when Yahoo's crumb-protected fields come back null. Free key: https://www.alphavantage.co/support/#api-key

How to Run

Invoke through the terminal tool. Once installed:

SCRIPT=~/.hermes/skills/finance/stocks/scripts/stocks_client.py
python3 $SCRIPT quote AAPL

All output is JSON on stdout — pipe through jq if you want to slice it.

Quick Reference

python3 $SCRIPT quote AAPL
python3 $SCRIPT quote AAPL MSFT GOOGL TSLA
python3 $SCRIPT search "Tesla"
python3 $SCRIPT history NVDA --range 6mo
python3 $SCRIPT compare AAPL MSFT GOOGL
python3 $SCRIPT crypto BTC ETH SOL

Commands

quote SYMBOL [SYMBOL2 ...]

Current price, change, change%, volume, 52-week high/low.

search QUERY

Find tickers by company name. Returns top 5: symbol, name, exchange, type.

history SYMBOL [--range RANGE]

Daily OHLCV plus stats (min, max, avg, total return %). Ranges: 1mo, 3mo, 6mo, 1y, 5y. Default: 1mo.

compare SYMBOL1 SYMBOL2 [...]

Side-by-side: price, change%, 52-week performance.

crypto SYMBOL [SYMBOL2 ...]

Crypto prices. Pass BTC (the script appends -USD automatically).

Pitfalls

• Yahoo Finance's API is unofficial. Endpoints can change or rate-limit without notice — if requests start failing, that's why.
• market_cap and pe_ratio may return null on quote when Yahoo's crumb session isn't established. Set ALPHA_VANTAGE_KEY to backfill.
• Add a small delay between bulk requests to avoid rate-limiting.
• This is read-only — no order placement, no account integration.

Verification

python3 ~/.hermes/skills/finance/stocks/scripts/stocks_client.py quote AAPL

Returns a JSON object with symbol: "AAPL" and a numeric price field.
