Scored across 5 tools
Each tool has a distinct purpose: find_arbitrage detects cross-platform arbitrage, get_category_markets browses by category, get_market_odds fetches specific odds, get_trending_markets shows trending markets, and search_prediction_markets searches by keyword. No overlap.
All tool names follow a consistent verb_noun pattern in snake_case. Most use 'get_' prefix, while 'find_arbitrage' uses 'find_' which is still a clear verb_noun construction. Naming is predictable and uniform.
Five tools cover the essential information retrieval needs of a prediction markets server: discovering, searching, browsing, and checking odds, plus a unique arbitrage detection tool. The count is well-scoped and not excessive.
The tool set covers major read operations: search, browse, trending, odds, and arbitrage. However, it lacks tools for historical data, market analysis, or user portfolio management, which are reasonable extensions for a more complete prediction markets server.
