The tools have clear distinctions between querying (inquery-*) and ordering (order-*), but within the querying tools there is significant overlap that could cause confusion. For example, inquery-stock-price, inquery-stock-info, and inquery-stock-ask all seem to retrieve stock price-related data with subtle differences that may not be immediately clear to an agent.

All tool names follow a consistent hyphen-separated pattern with a clear verb-noun structure (e.g., inquery-balance, order-stock). The naming is predictable and uniform across all 10 tools, making it easy for an agent to parse and understand the purpose of each tool.

With 10 tools, the count is well-scoped for a securities trading API, covering key operations like querying balances, orders, stock prices, and placing orders. Each tool appears to serve a distinct function within the domain, and the number is neither too sparse nor overwhelming.

The tool set provides comprehensive coverage for core trading operations, including querying various data (balances, orders, prices) and executing orders (domestic and overseas). A minor gap is the lack of tools for modifying or canceling orders, which might be necessary for full lifecycle management, but agents can likely work around this with the existing query and order tools.
