Preferred shares are listings too (on US exchanges symbols like JPM-PD), carrying the common stock's eps and market cap, so their pe_ratio means nothing. Returns total (all matches) and one row per match with price, valuation and dividend figures. A row's dividend_yield can be missing or differ markedly from the filter, which holds for Yahoo's screener data, not for that column.

Scored across 23 tools
Most tools map to one distinct data surface (quotes, history, financials, holders, options, filings, etc.), and descriptions explicitly separate tricky pairs like get_quote vs get_quotes (single vs batch) and get_sector/get_industry/get_market (key-based browsing vs tickers). The main residual overlap is corporate events: get_calendar returns upcoming earnings dates with estimates, while get_earnings also returns an earnings calendar — an agent could reasonably pick either. Minor overlaps like get_estimates vs get_recommendations are adequately differentiated by their descriptions.
Nearly the whole surface follows a clean snake_case get_<resource> pattern (get_quote, get_financials, get_insider_activity), which is highly predictable. The deviations are small: search and screen use bare verbs rather than the get_ prefix, and get_quote/get_quotes differ only by number, which is readable but the one place a typo could mis-route a call.
23 tools is on the high side, but the count reflects Yahoo Finance's genuinely broad data surface (quotes, statements, ownership, analysts, options, funds, screening, sector/market browsing) and no obvious redundant endpoint is added just for padding. It would be slightly better scoped if a few thin tools (get_shares, get_calendar) were folded into related ones, but each still earns its place.
Coverage is strong end-to-end: symbol discovery, quotes, OHLCV history, financial statements, dividends/splits, ownership, insider activity, analyst data, options chains, SEC filings, fund data, screening, and sector/industry/market browsing. Remaining gaps are modest (no peer/compare tool, no chart/technical or FX-specific surface, no streaming), all workable via existing tools.
