Conciseness

Each of the 12 routing sections is 1–2 lines of pure dispatch instruction with no concept explanations Claude already knows (no explanation of what Remotion or rendering is). The one explanatory clause ("By structuring the Remotion markup well, we can allow users to interactively change things in the Studio") exists to signal when that section applies, so every token earns its place — matching the 'Lean and efficient' anchor.

Actionability

Every section pairs a concrete condition ("If the user asks to make, create, or build a new video", "For static maps, animated routes and markers") with an exact action ("load [Create a new Remotion video](./remotion-create/SKILL.md)"). This is fully executable guidance for a router; per the scoring notes, absence of code in an instruction-only skill is not penalized when the guidance is this specific.

Workflow Clarity

The dispatch conditions are unambiguous and even handle edge cases ("whether or not a Remotion project already exists", "If no Remotion project currently exists"), plus a behavioral guard ("don't overwrite it, assume it was intentional or ask for confirmation"). As a single-purpose router with no destructive or batch operations, it meets the simple-skill exception for a top score.

Progressive Disclosure

The structure is textbook progressive disclosure — a concise overview with clearly signaled, one-level-deep references per topic — but scoring against the actual bundle shows none of the 12 referenced sub-skill files (./remotion-create/SKILL.md, ./remotion-markup/SKILL.md, etc.) exist in the bundle (only assets/remotion-icon.svg). This matches 'Good structure; most content is appropriately placed; references mostly clear; minor organization gaps' rather than a 5, since the navigation targets cannot be verified as present.

Specificity

The description is only "Router for all Remotion skills" — it names the domain (Remotion) but the only action named is the generic "Router". It matches the anchor 'Names the domain but actions are minimal or generic' (e.g. "Processes PDF files"), and is not entirely vague (score 1) because it does pin a concrete domain and role.

Completeness

The 'what' is stated at a high level (it routes among Remotion skills) but there is no 'when' clause at all — no 'Use when...' or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It does not reach score 4 because the 'what' is also thin, naming no concrete capabilities.

Trigger Term Quality

"Remotion" is a distinctive, natural keyword a user would say, but it is essentially the only trigger term; there are no variations or synonyms like video, composition, render, or React video. This fits 'Some relevant keywords but missing common variations or synonyms'; it is above score 2 because "Remotion" is highly specific rather than generic.

Distinctiveness Conflict Risk

"Remotion" carves out a clear niche with minimal conflict risk against unrelated skills, matching 'Mostly distinct; minor overlap risk with closely related skills'. It falls short of score 5 because the description gives no explicit trigger phrases to distinguish this router from the individual Remotion sub-skills it dispatches to.
