Scored across 34 tools
Multiple overlapping families make tool selection ambiguous: ask_pipeworx vs ask_pipeworx_beta vs ask_pipeworx_grounded, deep_research and validate_claim; polymarket_edges vs polymarket_arbitrage vs polymarket_fill_risk vs bet_research; and entity_profile vs compare_entities vs resolve_entity vs recent_changes. Descriptions are detailed, but several tools appear to do closely related or identical work, so an agent can easily misselect.
Most names use snake_case, but the verb/noun convention is mixed: some lead with actions (ask_, compare_, validate_, discover_), while others lead with domain or product nouns (entity_profile, ai_visibility_check, polymarket_edges, pipeworx_feedback). The surface is readable but lacks a single predictable pattern.
At 34 tools, this is a heavy surface for a coherent set. Several tools are variants or near-duplicates, and the dense polymarket cluster plus many meta-tools increases selection burden. The count exceeds the rubric’s 25+ threshold for 'too many.'
The set covers broad lifecycle needs: discovery, grounded research, entity resolution, validation, memory, subscriptions, feedback, and prediction-market analytics. Minor gaps exist, such as no explicit citation-fetch/read tool or subscription update operation, but core workflows are covered.
