Each tool targets a distinct concern: source discovery, schema introspection, live fetching, history querying, searching, trend analysis, and storage stats. The main potential confusion is between query_history and search_history, but the descriptions make clear that querying returns persisted items with pagination while searching targets content and returns attributable evidence, which differentiates them sufficiently.

Names mostly follow a verb_noun pattern with clear action prefixes (list_, get_, fetch_, query_, search_, get_). There's a minor deviation with get_source_schema vs fetch_current where 'fetch' and 'get' use different verbs for similar acquisition actions, but this is arguably intentional given that fetch_current accesses the network while get_source_schema is local.

Seven tools is within the ideal 3-15 range and each tool appears to earn its place by covering a distinct dimension of the domain: discovery, introspection, live fetch, history retrieval, search, analytics, and storage management. No redundant or filler tools.

The surface covers the full lifecycle: source discovery, schema understanding, live fetching, persistence querying, search, trend analytics, and storage management. Minor gaps exist—such as the absence of explicit history write/capture control (though fetch_current implies an upstream capture mechanism) and possibly pagination/sampling controls for trend series—but no obvious dead ends that would cause agent failures.
