TDQS

A3.9/5.0

Scored 2026-10-20 09:20 across 43 tools

Disambiguation2/5

Several tools have genuinely overlapping purposes: ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, and deep_research all route natural-language questions, and ask_pipeworx_beta currently does the exact same thing as ask_pipeworx. The prediction-market cluster (bet_research, polymarket_edges, polymarket_arbitrage, polymarket_edge_tracker, polymarket_fill_risk, polymarket_kalshi_spread, kalshi_weather_edge) also has fuzzy boundaries that make misselection likely, even though the descriptions try to differentiate them.

Naming Consistency4/5

Almost everything is snake_case, and the dominant pattern is verb_noun (archive_compare, get_snapshot, resolve_entity, validate_claim). A few names are noun_noun or hybrid (ai_visibility_check, company_facts, entity_profile, polymarket_edge_tracker), but they remain readable and predictable.

Tool Count2/5

43 tools is far beyond the 3-15 well-scoped range and is especially heavy given the server is labeled 'Wayback' when only a handful of tools actually concern web archiving. The surface is a broad platform bundle rather than a focused archive toolset, so many tools do not clearly earn their place in this server.

Completeness3/5

The archiving subset (get_snapshot, list_snapshots, get_capture_count, archive_evidence, archive_compare) covers read-side discovery and comparison well, and the wider Pipeworx tools cover many adjacent workflows. However, the surface is scattered across unrelated domains with no coherent lifecycle for any single purpose, so it is neither obviously complete nor severely lacking for the stated 'Wayback' purpose.
