Scored across 5 tools
Each tool has a clearly distinct purpose: begin starts a session, capture saves a moment, export exports data, finish closes a session, and trail lists sessions or moments. There is no overlap or ambiguity.
All tools follow a consistent pattern: 'shared_margin_' prefix followed by an imperative verb (begin, capture, export, finish, trail) in snake_case. No deviations.
5 tools is appropriate for the domain of shared-attention sessions, covering creation, capture, export, closing, and listing. Neither too sparse nor excessive.
The tools cover the main lifecycle (begin, capture, export, finish, list/read). Missing update or delete operations for moments/sessions, but these are not essential for basic use. Minor gap.
