Scored across 32 tools
Descriptions are unusually verbose and explicitly tell the agent when to prefer each tool, but the set contains several overlapping entry points: ask_pipeworx, ask_pipeworx_beta (currently identical to stable), ask_pipeworx_grounded, deep_research, bet_research, validate_claim, compare_entities, entity_profile and recent_changes all answer questions from Pipeworx data with only subtle boundary differences. Polymarket tools (edges vs arbitrage vs edge_tracker vs bet_research) and ai_visibility_check vs scan_competitor_ai_presence also overlap. An agent can usually pick correctly, but misselection is plausible.
Every tool uses snake_case and follows recognizable prefix families (ask_pipeworx_*, polymarket_*, pipeworx_*, scan_*), which reads consistently. The verb_noun pattern is not universal — many are noun-first (entity_profile, ai_visibility_check, bet_research, recent_changes) — but the convention is coherent rather than chaotic.
32 tools is well above the 3-15 well-scoped range and past the 25+ 'too many' threshold, even for a broad data gateway. Several slots are near-duplicates (ask_pipeworx_beta identical to ask_pipeworx) or tangential outliers (yesterdays_number_get, generate_llms_txt), so not every tool clearly earns its place.
Across its apparent domains the surface is strong: memory has remember/recall/forget, subscriptions have subscribe/list/recent_alerts/unsubscribe, entity work has resolve/profile/compare/change-feed, and Polymarket betting is covered from research through arbitrage, edges, decay telemetry, fill risk and cross-venue spreads. Gaps are minor (e.g. no direct low-level record-fetch or update primitives outside the routers), which agents can work around.
