TDQS

A3.8/5.0

Scored 2026-10-16 06:20 across 14 tools

Disambiguation4/5

Most tools target clearly distinct resources (weather, arXiv, PubMed, SEC, Polymarket), but the crypto cluster has two confusable pairs: eip712_decode vs explain_before_sign (decode vs verdict) and x402_lint vs x402_payment_safety_check (header lint vs endpoint pre-payment check). The descriptions do a good job of distinguishing them, and calldata_decode overlaps somewhat with explain_before_sign's decoding, but boundaries remain workable.

Naming Consistency5/5

Every tool uses snake_case with a consistent resource_action pattern (arxiv_search, calldata_decode, evm_address_lookup, url_unfurl, weather_forecast, x402_lint). No mixed conventions, camelCase, or vague verbs anywhere in the set.

Tool Count5/5

14 tools falls squarely in the well-scoped 3-15 range, and each tool covers a discrete utility (research, web fetch, crypto safety, data lookups) with no obvious redundancy. For a broad 'agent utilities' server, this count is reasonable and each tool earns its place.

Completeness4/5

Each utility is largely self-contained and complete for its stated purpose, and the crypto safety workflow (decode, pre-sign, x402 checks) is well covered. Minor gaps exist, such as search-only arXiv/PubMed with no fetch-by-id and Polymarket offering only market data with no orderbook, but agents can work around these.
