TDQS

A3.6/5.0

Scored 2026-08-09 14:10 across 16 tools

Disambiguation5/5

Each tool targets a distinct resource (portfolios, ledger, assets, orders, instruments, notifications, etc.), with clear boundaries. The only potential overlap is get_notifications vs. get_unread_count, but they are distinctly a list vs. a count, so there is no real ambiguity.

Naming Consistency5/5

All tool names follow a consistent snake_case verb_noun pattern (get_*, place_order, cancel_order, list_orders). The few non-get_ prefixes are still action-based and consistent with the overall style, with no mixing of camelCase or other conventions.

Tool Count4/5

The 16 tools are at the upper edge of a well-scoped set, but each one serves a distinct purpose and contributes to the trading/portfolio domain. The count is slightly high but not excessive, and no tools feel redundant or trivial.

Completeness4/5

The tool surface covers the core trading workflow well: portfolio management, order lifecycle, market data, and notifications. However, there are notable gaps such as order modification and withdrawal functionality, which are common in trading platforms and would be expected for full lifecycle coverage.
