Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly specifies: 'Live macro snapshot: DXY, US10Y yield, S&P 500, gold, VIX (Yahoo Finance free) + BTC dominance, ETH/BTC, total crypto market cap (CoinGecko free). Plus a coarse RISK_ON / RISK_OFF / MIXED regime.' This is a specific verb+resource combination that distinguishes it from siblings like get_basic_macro and get_market_context.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
