What probably matters to youSection of the release
The /artifact-diagramming skill is registered but only appears behind the artifact gate, off by default.
What
A user-invocable command serves guidance on when a diagram earns its place in an Artifact and how to hand-author inline SVG for it.
Details
Registers under the name artifact-diagramming with menu text "Diagramming guidance for Artifacts".
Covers viewBox sizing, currentColor theming, marker arrowheads, figure/figcaption with role="img", and no script, style or foreignObject inside the SVG.
The workshop skill's instructions were updated to load it alongside artifact-capabilities during setup.
