The body is lean and assumes Claude's competence — it gives file paths, fields, and a code block with no concept-explaining padding like 'what is Remotion'.

Concrete file paths, a complete copy-paste-ready DemoType registration object with all required fields, and specific option-type schemas provide fully executable guidance.

A clear four-step sequence (create, register, add to array, use in MDX) is well ordered; the task is additive and non-destructive, so the absence of an explicit validation checkpoint does not trigger the level-2 cap.

A single-purpose skill under 50 lines with no external references, organized into clear sections (Steps, Options, Example registration), qualifying for the simple-skill full score.

It names the domain (Remotion docs) and one concrete action ("Add an interactive demo") but does not list multiple specific concrete actions like the level-3 anchor.

It states what ("Add an interactive demo to the Remotion documentation") and an explicit when ("Use when creating a new <Demo> component for docs pages"), satisfying both halves.

"creating a new <Demo> component" and "docs pages" are exactly the natural terms a user working on Remotion docs would say, giving good coverage for this niche.

The Remotion docs demo niche with a distinct <Demo> trigger is unlikely to overlap with unrelated skills.
