Conciseness

The body is efficient: each section is a short rule followed by a compact example, with no explanation of what Remotion or React is, and good/bad contrast is expressed via inline code rather than prose ('// 👍 ... // ❌ ...'). It is not a 5 because a few spots could be trimmed — e.g. the 'Be sensible, if a component has many elements, the timeline might get messy' aside and the somewhat long bad-interactivity examples restate points already made.

Actionability

Every rule is paired with copy-paste-ready JSX/TSX covering the common cases (Interactive.Div, inline interpolate() with input-range rules, Interactive.Path with interpolatePaths(), inline Composition metadata, inline effects arrays), plus a concrete install command ('bunx remotion add @remotion/paths'). Negative examples are equally concrete, showing exactly which patterns break Studio interactivity.

Workflow Clarity

This is a single-purpose style-guide skill with no destructive or batch operations, so no validation checkpoints are required; each rule is unambiguous, consistently structured (directive → example → counter-example), and the interpolate() input-range rules are spelled out precisely (allowed: durationInFrames, fps, width, height from useVideoConfig(), bare identifiers, n * fps, durationInFrames - 1). It falls short of 5 only because some sections defer detail to external links ('see [Video editing]...') without indicating when in the authoring flow that guidance applies.

Progressive Disclosure

The body is well-organized into clear H2 sections with one-level-deep external pointers (the Studio docs link and the sibling video-editing skill link), and the SVG asset bundle is used only as an icon. It is not a 5 because at ~310 lines some self-contained subsections (SVG path morphing, composition metadata, effects) could arguably live in reference files, and the external links are plain URLs rather than well-signaled bundle references.

Specificity

The description 'Structure Remotion markup for interactivity' names the domain (Remotion markup) and one concrete action (structuring markup for interactivity), which matches the anchor for naming domain plus 1-2 concrete actions but falling short of comprehensive coverage. It sits above anchor 2 because the action is tailored rather than generic ('Processes PDF files'), but below anchor 4 because only a single action is stated with no enumeration of what 'interactivity' enables.

Completeness

The 'what' is clear and concrete (structure Remotion markup so it becomes interactive), but the 'when' is entirely absent — there is no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It is not a 4 because a usable trigger condition ('Use when authoring Remotion templates...') is not even weakly implied.

Trigger Term Quality

'Remotion', 'markup', and 'interactivity' are natural terms a user working with Remotion would say, giving some relevant keywords. However, common variations and synonyms are missing — no mention of 'Remotion Studio', 'templates', 'animations', 'keyframes', or 'editing in the Studio' — matching the 'some relevant keywords but missing common variations' anchor.

Distinctiveness Conflict Risk

'Remotion' is a clear niche that would not trigger for unrelated skills, so it sits above the overlap anchors. It falls short of 5 because 'interactivity' is broad and the skill body references a closely related sibling skill (remotion-markup/video-editing) covering adjacent Remotion-markup territory, creating minor overlap risk with closely related Remotion skills.
