A3.9/5.0

Scored across 18 tools

Disambiguation4/5

Most tools have clearly distinct purposes (articles, episodes, dossiers, indexes, market reports, report entries, changes, gatherings, markets, pillars, search, status), and the descriptions explicitly warn about near-misses (calendar vs Gatherings pillar, search vs article list). The main confusion source is the trio of stub tools (card sold comps, coin sold comps, PSA cert) which all nominally do 'pricing/grade lookup' and do nothing, plus comps_status being adjacent. Still, explicit 'do not call' guidance keeps the set largely separable.

Naming Consistency4/5

All tools share an 'attic_' prefix and mostly follow a verb_noun pattern: get_*, list_*, lookup_*, search, status. Deviations are the noun-style names (attic_comps_status, attic_card_sold_comps, attic_coin_sold_comps, attic_search, attic_status), which are readable but break the verb convention. Overall predictable with minor inconsistencies.

Tool Count3/5

18 tools is on the heavier side for a read-only content/API connector, though each read tool maps to a distinct resource. Notably 3-4 of the 18 (the sold comps and PSA cert stubs plus comps_status) are non-functional or status-only, so several slots do not earn their place. Borderline rather than well-scoped.

Completeness4/5

The read surface covers the domain well: articles, episodes, dossiers, indexes, market reports and entries, changes ledger, gatherings calendar, market and pillar lists, plus search and status. Minor gaps exist (e.g. no single-gathering detail lookup), and the advertised pricing/comping capability is entirely stubbed, so agents seeking sold prices hit a dead end. Core content workflows are complete.
