Stock Snapshot

Q: How do I know the Stock Snapshot output is good?

The skill verifies itself against its own quality checks: The ticker's exchange and currency are printed with the price; The timestamp is converted and the open/closed state stated; The unofficial-and-possibly-delayed line appears verbatim in spirit; Weird responses are reported, never smoothed into a made-up price.

Fetch a stock quote snapshot with keyless curl — Yahoo Finance's public chart endpoint, read with the discipline unofficial market data demands: timestamped, delayed-flagged, and never advice. Use when asked what's this stock at, how did the market do today, get me a ticker's recent range, or pull basic price history. Produces the quote with change and range context, the source-honesty caveats (unofficial, possibly delayed), the rerunnable command, and a hard no-advice line.

What to give it

▸The ticker — resolved carefully: company names map to multiple listings ("did you mean the NYSE or Frankfurt listing?"); exchange suffixes matter (`SAP.DE` vs `SAP`) and the wrong-listing answer is confidently wrong in the wrong currency

▸What they actually want — a number, a day summary, or a range/history — shapes which fields get read

▸Why (lightly) — curiosity gets the snapshot; anything that smells like a trading decision gets the snapshot *plus* the this-is-not-the-data-for-that sentence

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓The ticker's exchange and currency are printed with the price

✓The timestamp is converted and the open/closed state stated

✓The unofficial-and-possibly-delayed line appears verbatim in spirit

✓Weird responses are reported, never smoothed into a made-up price

✓The no-advice fence held, including against indirect asks

⚠️ What it refuses to do

Do not answer prices from memory — a remembered stock price is historical fiction

Do not resolve ambiguous tickers silently — the wrong listing is the classic confident error

Do not describe chart history in predictive language — shapes are described, futures are not

Do not present this endpoint as trading-grade — the fence is part of the answer

Do not give investment advice under any phrasing — the refusal is the skill working
