Scored across 34 tools
Most tools target distinct purposes, but the ask_pipeworx / ask_pipeworx_beta / ask_pipeworx_grounded trio overlaps heavily (beta currently identical to the base), and the six polymarket_* tools plus bet_research require close reading to separate. The long descriptions do provide strong disambiguation signals, so boundaries are mostly recoverable.
Mostly snake_case, but conventions are mixed: some tools are verb_noun (compare_entities, resolve_entity, validate_claim), while many are noun-only or phrase-like (entity_profile, recent_changes, deep_research, bet_research, discover_tools). Vendored prefixes (crawlbase_, pipeworx_) are used inconsistently, adding to the lack of a single predictable pattern.
34 tools is well above the 15-tool sweet spot and lands squarely in the 'too many' band, making the surface hard to scan and select from. The breadth (scraping, finance, polymarket, memory, subscriptions, meta) partially justifies it, but several clusters (ask_pipeworx variants, six polymarket tools) could be consolidated.
Coverage is broad and thoughtfully rounded: scraping (scrape/screenshot/structured), entity resolution and profiling, comparison, claim validation, memory CRUD (remember/recall/forget), and full subscription lifecycle (subscribe/unsubscribe/list/recent_alerts). Minor gaps exist in some sub-domains but graceful-degradation notes and explicit resolution contracts make the surface workable.
