Each tool maps to a distinct lifecycle stage: create a new diagram, fetch an existing diagram, or modify an existing diagram. There is no overlap in purpose or ambiguous boundary between them. Even though create_diagram and edit_diagram both accept graph semantics, their roles are clearly separated by whether the diagram already exists.

All three tool names follow the exact same verb_noun snake_case pattern: create_diagram, edit_diagram, get_diagram. This is perfectly predictable and consistent with no mixed conventions or vague verbs.

Three tools is a reasonable, focused surface for a diagram creation and editing server. It is slightly minimal, but the three tools cover the core authoring loop well and each earns its place. A fourth tool for deletion or listing would make it feel more complete, but the current count is not problematic.

The core lifecycle of create, read, and edit is fully covered, including rich granular operations through edit_diagram. The obvious gap is the lack of a delete_diagram operation and no way to list diagrams, but these are workable omissions for the server's apparent purpose. Agents can still accomplish the main diagram-authoring workflow without dead ends.
