Example Conversations

1 — Market News via get_market_news

User: Give me the latest news on crypto.

Claude:

Here's what's moving in crypto right now:

Bitcoin under pressure — BTC has dropped to the $58K range, with multiple analysts framing the $58K level as "normal" under power-law models, but options traders are actively hedging downside as uncertainty lingers. Some bears are eyeing sub-$50K as a next target if support doesn't hold. (Cointelegraph)

Coinbase Base outage — Coinbase's Base L2 blockchain suffered a two-hour outage earlier today before resuming. No details yet on the root cause, but it's a notable reliability event for one of the more actively used L2 networks. (CoinDesk)

Crypto "invisible" to UK wealth advisers — A CoinShares survey found that half of UK wealth advisers have no visibility into their clients' crypto holdings, pointing to a structural gap in portfolio oversight as adoption grows. (Cointelegraph)

The dominant theme is BTC sentiment — the market's watching whether $58K holds or if there's more downside ahead.

2 — Company Profile via get_company_profile + get_stock_quote

User: Give me a short company profile on SOFI.

Claude:

SoFi Technologies (SOFI) · NASDAQ · Financial Services

Trading at $17.30 today (nearly flat, –0.06%), with a market cap of ~$22.2B. Notable: it's sitting –47.1% below its 52-week high of $32.73 — well past the 20% flag threshold.

What they do: SoFi is a digital-first financial services company targeting "HENRYs" (high earners, not rich yet) — young professionals refinancing student loans or looking for a one-stop-shop bank. Their product stack covers personal loans, student loan refinancing, home loans, a cash management account, investing, and credit cards. They secured a full bank charter in early 2022, a significant milestone that lets them hold deposits and fund loans directly.

The infrastructure play: SoFi also owns Galileo (acquired 2020) and Technisys (acquired 2022) — B2B fintech infrastructure businesses that power card issuing and banking platforms for other fintechs. This gives them a revenue stream beyond consumer finance and makes them something of a picks-and-shovels play on fintech broadly.

Things to watch: Growth has been strong but profitability has been a moving target. The student loan environment (government policy on repayments) has historically been a headwind or tailwind depending on the cycle. At –47% from peak, it's deeply discounted — but worth a closer look at net interest margin and loan quality trends before forming a view.

3 — Watchlist Snapshot via watchlist-snapshot prompt

User: (selected the watchlist-snapshot prompt and watchlist://my-tickers resource from the Claude chat UI)

Claude:

Got the tools. Now let me pull quotes with 52-week data for all 5 tickers simultaneously... All quotes in. Now let me grab the MSFT profile — it's the one furthest off its peak... Here's the full picture. A few key takeaways:

Potential buys (>20% below 52-week peak):

MSFT is the standout at –36.5% off its high of $555.45 — the largest drawdown in the watchlist by a meaningful margin. That's a significant pullback for a company of its quality and suggests the market has repriced it substantially, though a drop of that magnitude warrants understanding the catalyst (macro rates, valuation compression, Azure growth deceleration) before treating it as a simple entry.

META is also flagged at –31.8% off $796.25, down another 2.65% today. Still generating massive FCF and expanding its AI/advertising stack, so this is worth watching closely.

Not triggered:

NVDA is just under the threshold at –17.2%, trading at $195.74 vs. its $236.54 peak. Close, but not quite there by the 20% rule.

MU is on an absolute tear — up 15.7% today alone and sitting right at its 52-week high of $1,213.56.

BRK.B caveat: Finnhub's 52-week data for BRK.B came back clearly wrong (returning BRK.A Class A figures near $775K). The current price of $487.81 looks plausible for BRK.B, but I excluded it from the peak-distance analysis entirely rather than surface bad numbers. Worth checking a second source on that one.

Not financial advice.
