TDQS

A3.6/5.0

Scored across 40 tools

Disambiguation3/5

Several clusters overlap heavily: the ask_pipeworx / ask_pipeworx_beta / ask_pipeworx_grounded / deep_research family are four near-identical routers distinguished only by nuanced prose, and polymarket_edges / polymarket_arbitrage / polymarket_edge_tracker / bet_research all answer 'where is the edge'. The astronomy tools (catalogs, query_catalog, cone_search, object) and resolution_audit vs resolution_diff also blur. Descriptions work hard to steer selection, which keeps it from being worse, but an agent will misselect within these groups.

Naming Consistency3/5

Everything is snake_case, which is consistent at the casing level, but the structural conventions are mixed: verb_noun (discover_tools, resolve_entity, validate_claim, search_within), noun-only (entity_profile, company_facts, recent_changes, resolution_audit), domain-prefixed (polymarket_*, kalshi_*, pipeworx_*), and bare nouns (catalogs, object). Readable but not a single predictable pattern.

Tool Count2/5

40 tools is heavy by the rubric's 25+ threshold and includes real redundancy — four overlapping router/research tools and four overlapping Polymarket opportunity scanners that could be collapsed. The enormous domain breadth (astronomy, markets, SEC, memory, subscriptions, AI marketing) explains the count, but several tools do not earn a distinct place.

Completeness4/5

Coverage is broad and lifecycle-complete in most areas: memory has remember/recall/forget, subscriptions have subscribe/unsubscribe/list_subscriptions/recent_alerts, entity data spans resolve/company_facts/entity_profile/compare_entities/recent_changes, and markets have research, edge, arbitrage, fill-risk, and resolution tooling. Only minor gaps remain (e.g. no explicit memory update/overwrite tool distinct from remember).
