Conciseness

The body is dense with non-generic, operational content — exact CSS values, duration tables, frequency tiers, grep patterns — and assumes Claude's competence (no explanation of what transitions or easing are). Minor trimmable instances remain: the "Operating Posture" framing paragraph and editorial asides like "This section is what separates this skill from an animation wishlist". Not 5 because a few sentences are motivational rather than instructional.

Actionability

Fully executable throughout: exact recipes ("transform: scale(0.97)" with "transition: transform 160ms ease-out", "clip-path: inset(0 100% 0 0)" hold-to-confirm timings), spring configs ("{ type: \"spring\", duration: 0.5, bounce: 0.2 }", bounce 0.1–0.3), a velocity threshold (~0.11), concrete grep sweeps ("{isOpen &&", "display: none"), and a worked output-format example with two filled-in table rows. Not 4 because the concrete examples cover the common cases end to end, including named tokens and reduced-motion/hover-pointer gating requirements.

Workflow Clarity

Clear four-step sequence (Recon → Sweep → Gate → Report) with an explicit completion criterion ("Done when every seam class has either yielded candidates with file:line evidence or been explicitly cleared") and the four-question Gate as a per-candidate checkpoint whose answers are recorded. Not 5 because the validation checkpoints live in separate sections (the Gate, the output format's token-verification rule) rather than in the workflow steps, and there is no re-check loop; not 3 because the sequence, exit criteria, and gating are all explicit.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are all absent) and none are needed: every section — Hard Rules, The Gate, Where to Hunt, Workflow, Required Output Format — is load-bearing on every invocation, so a single well-sectioned SKILL.md is the appropriate structure. Clear headers make navigation trivial. Not 4 because there is no content that clearly belongs in a separate file and no organization gaps.

Specificity

Multiple concrete actions are named in third person: "Search a codebase or UI for places that don't animate but should", "reject everything that shouldn't", "proposes motion with exact values", "it does not implement it" — comprehensive coverage including scope boundaries (read-only, no implementation). Not 4 because coverage includes both the finding and rejecting actions plus explicit non-goals, matching the comprehensive anchor.

Completeness

Explicitly answers both what ("Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't... proposes motion with exact values, it does not implement it") and when ("Use when the user asks 'what could be animated here?' or wants to 'make this feel more alive'") with concrete trigger phrases, plus a when-not clause. Matches the top anchor exactly.

Trigger Term Quality

Natural quoted phrases users would say are present ("what could be animated here?", "make this feel more alive") with good keyword coverage (animate, animation, motion). Not 5 because common synonyms like "add motion", "micro-interactions", or "UI feels flat" are missing; not 3 because the included phrases are genuinely natural user utterances, not technical jargon.

Distinctiveness Conflict Risk

Clear niche (opportunity finding, explicitly read-only and non-implementing) with explicit disambiguation: "For fixing existing animations, use improve-animations or review-animations instead." Minimal conflict risk with closely related sibling skills. Not 4 because the routing away from adjacent skills is explicit rather than merely implied.
