PTLam Mermaiding

Create, revise, or review Mermaid diagrams. Each diagram answers one visual question, keeps the real relationships, reads as plain text, has valid syntax, and renders on its target. This skill owns diagram choice and source; the surrounding document owns its argument, prose, and placement.

A review is read-only. Change a file only with the user's permission; otherwise return a fenced mermaid block.

How does one visual question become a verified diagram?
