Scored across 9 tools
Most tools are clearly distinct: quote, summary, holdings, performance, search, similar, overlap, compare. The only potential confusion is get_etf_holdings vs get_etf_full_holdings, but the descriptions explicitly differentiate Yahoo top-10 vs SEC full holdings.
All tools follow a consistent get_/compare_/search_ verb + etf(s) noun pattern. The pattern is predictable: get_etf_quote, get_etf_summary, get_etf_holdings, get_etf_performance, get_etf_full_holdings, get_etf_overlap, get_similar_etfs, compare_etfs, search_etfs.
9 tools is well within the ideal 3-15 range and each tool covers a distinct research need: quotes, summary, holdings, performance, search, comparison, similarity, overlap, and full SEC data.
The surface covers the core ETF research workflow well: search, quote, summary, performance, holdings, comparison, overlap, and similar funds. Minor gaps: no historical dividend data, no expense-ratio-specific comparison beyond compare_etfs, and no tool for ETF news or analyst ratings, but these are not essential.
