The two tools target different output types and inputs: one exports whole Markdown plans/audits, the other renders isolated Mermaid diagrams. There is mild potential for confusion when a plan includes diagrams, but the descriptions make the boundary clear.

Both tools follow the same verb_noun pattern: export_plan and render_diagram. The naming is parallel, predictable, and accurately reflects each tool's function.

With only two tools, the server feels thin but is still reasonably scoped for a narrow plan-export and diagram-rendering purpose. It is not bloated, yet it sits at the lower boundary of acceptable tool count.

The core workflows are covered: exporting plans to common document formats and rendering diagrams to image formats. Minor gaps exist, such as batch processing or combining plan text and diagrams into a single export, but agents can accomplish the primary tasks without dead ends.
