Scored across 51 tools
Several clusters overlap heavily: ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded and deep_research are four near-identical routers (the beta is documented as currently identical to stable), the twelve open_payments_* tools split hairs between search/company/history/physician/product variants, and polymarket_edges/arbitrage/fill_risk/edge_tracker/kalshi_spread all circle the same mispricing question. The very long descriptions do a decent job of stating when to prefer each one, but an agent still faces genuine boundary decisions. entity_profile vs compare_entities vs recent_changes vs company_facts is similarly close.
Everything is snake_case with no camelCase or casing drift, and there is clear prefix grouping (open_payments_*, polymarket_*, archive_*, pipeworx_*). The pattern is mixed verb_noun (validate_claim, generate_llms_txt, list_subscriptions) vs noun_phrase (entity_profile, company_facts, resolution_audit) rather than one predictable convention, but it stays readable and predictable by group.
51 tools is heavy even for a broad multi-source gateway, and the surface is padded: four router variants, six Polymarket tools, twelve Open Payments tools, plus meta/onboarding/feedback tools. Several tools (ask_pipeworx_beta vs ask_pipeworx, a redundant edge tracker) exist without earning a distinct slot from an agent's perspective.
Coverage of the payment domain is thorough — search, by-company, by-physician, by-product, research payments, cross-year histories, nature breakdown, company comparison, top-spender ranking — plus memory, subscriptions, alerts and identity resolution around it. Gaps are acknowledged and worked around (live all-manufacturer ranking deliberately offloaded to an offline summary), so agents rarely hit an unrecoverable dead end.
