Beautiful is taste and self-contained is a file property. Verifiable is the word that puts a diagram under review, which is an unusual promise for generated output to make about itself.
A generated diagram that claims to be checkable invites someone to check it. That is a promise with a failure mode attached, which most output tools avoid making.
Naming crisp export means the artifact leaves the tool. A diagram you can drop into a document outlives the session that produced it.
No verification method, no example diagram, no export format list. The trending description names five kinds and three adjectives and nothing else.
Concept mock, not affiliated with the project. The five diagram kinds and the three output claims are quoted from the repository's own GitHub Trending description on 28 August 2026: "Agent skill for beautiful, verifiable architecture, workflow, sequence, data-flow, and lifecycle diagrams, self-contained HTML with motion and crisp export." The five icons are generic drafting marks drawn for this mock and represent no output from the tool.
