The three tools have clearly distinct roles: inspect_place retrieves place context, inspect_person retrieves person/compare context, and search_atlas performs cross-entity discovery. While search can surface cities or figures also handled by the inspect tools, the search-vs-inspect boundary is explicit and easy for an agent to apply.

All names follow a consistent verb_noun pattern: inspect_place, inspect_person, search_atlas. The convention is predictable and readable, with no mixing of camelCase, vague verbs, or inconsistent action styles.

Three tools is minimal but reasonable for a focused read-only historical atlas: one discovery tool and two entity-specific inspectors. It sits at the low end of the appropriate range, so it is slightly thin but not mismatched to the purpose.

The surface covers the core read-only workflows: search across the atlas, inspect a place or route, and inspect/compare people. Minor gaps remain, such as no dedicated timeline/era browse or explicit list operation, but search_atlas mitigates these enough that agents can work around them.
