+- User wants to look up a ticker by company name
+- User wants OHLCV history or performance over a date range

+- User asks for a crypto price (BTC, ETH, SOL, ...)
 
 ## Prerequisites
-Python 3.8+ stdlib only. No pip installs.
-Script path: `~/.hermes/skills/finance/scripts/stocks_client.py`
 
----
+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.

 ## Pitfalls
-- Yahoo Finance API is unofficial and may change without notice.
-- market_cap and pe_ratio may return null (require session crumb).
-- Rate limits: add delays between bulk requests.
 
----
+- 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
-```bash
+
-python3 ~/.hermes/skills/finance/scripts/stocks_client.py quote AAPL
 ```
+python3 ~/.hermes/skills/finance/stocks/scripts/stocks_client.py quote AAPL
+```
+
+Returns a JSON object with `symbol: "AAPL"` and a numeric `price` field.
