+:::
+
+# 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.
