TDQS

B3.3/5.0

Scored across 34 tools

Disambiguation2/5

Multiple tools have heavily overlapping purposes: ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research, discover_tools, and validate_claim all perform question-answering against the same underlying data catalog, distinguished only by subtle differences in routing, hallucination resistance, or grounding. Polymarket tools (bet_research, polymarket_arbitrage, polymarket_edges, polymarket_edge_tracker, polymarket_fill_risk, polymarket_kalshi_spread) also blur together—arbitrage, edges, and spread scans all find mispricings. An agent could easily choose wrongly among these near-duplicates.

Naming Consistency3/5

The server mixes namespaces: deck-of-cards tools (draw_cards, new_deck, shuffle_deck), Pipeworx meta-tools (ask_pipeworx, discover_tools), and polymarket tools all use verb_noun snake_case consistently for basics, but specific arcane tools like polymarket_kalshi_spread and ask_pipeworx_beta follow less obvious patterns. Overall readable but not highly predictable.

Tool Count2/5

34 tools is too many for a coherent single server. The mix of card-game primitives, a giant data-retrieval gateway, memory management, subscription management, and prediction-market scanners suggests several distinct servers merged into one, bloating the surface. The catalog's apparent scope—a deck-of-cards API plus a massive Pipeworx gateway—is an extreme mismatch.

Completeness3/5

For deckofcards the card lifecycle (new_deck, draw_cards, shuffle_deck) is fairly complete, but no discard/peek/return-card tools exist and the Pipeworx/data-gateway side is sprawling without covering obvious operations like advanced filing queries or all subscription delivery channels. Missing tools are notable but core flows are covered.

Pass the ENTITY NAME ONLY — for a bond that is the ISSUER exactly as printed (\"NEW YORK ST DORM AUTH\"), never the question's full noun phrase (\"NEW YORK ST DORM AUTH revenue bonds\"): the FIGI lookup matches instrument names, so trailing security-class words match nothing."
