Conciseness

The body is dense and assumes Claude's competence — no background on Figma or animation concepts — with every section adding non-obvious, skill-specific knowledge. It is not a 5 because the 'Verifying the animation' section restates its cost principle three times ('make each render count', 'every render carries real overhead, so make each one count', 'once you've paid for the render, mine it'), a minor trimmable redundancy.

Actionability

Fully executable guidance throughout: exact API names, exact public enum values ('EASE_IN_AND_OUT', never 'EASE_IN_OUT'), the exact easing object shape, concrete parameter values (constraint WIDTH 320, quality 'low', fps 5), and a copy-paste frame-extraction command ('ffmpeg -ss <t> -i anim.mp4 -frames:v 1 frame_<t>.png'). Specific examples cover the common cases.

Workflow Clarity

Clear sequence with explicit validation and error-recovery feedback loops: runtime gating with bail-out instruction on the 'not a supported API' error, a numbered render-planning sequence, an iterate-until-right loop ('batch every fix into one pass before re-rendering'), and a pre-flight checklist — matching the top anchor with checkpoints, feedback loops, and checklists.

Progressive Disclosure

A ~90-line overview with a well-signaled reference table ('When to load' / 'What it covers' columns) pointing to four one-level-deep references, all of which exist as substantial files (169–592 lines). Content is appropriately split between the overview and reference docs, and navigation is easy.

Specificity

The description names the domain and five concrete capability areas — 'manual keyframes, animation styles, easing, and timeline duration' plus 'custom animation styles' — matching the several-specific-actions anchor. It is not a 5 because text/typewriter animation (an entire reference doc in the bundle) is a minor coverage gap absent from the description.

Completeness

Explicitly answers both: what ('animating Figma nodes via manual keyframes, animation styles, easing, and timeline duration' plus custom animation styles) and when ('Load alongside figma-use whenever a task involves adding, editing, or inspecting animation on a node') — concrete trigger phrases, matching the top anchor exactly.

Trigger Term Quality

Natural terms users would say are comprehensively covered with synonyms: 'Motion / animation', 'animating Figma nodes', 'manual keyframes', 'animation styles', 'easing', and 'adding, editing, or inspecting animation on a node'. No plausible natural variation for this domain is missing.

Distinctiveness Conflict Risk

Clear niche — the time/motion dimension of Figma work via the `use_figma` MCP tool — with distinct triggers (keyframes, easing, animation styles). The relationship to the parent figma-use skill is explicitly managed ('Load alongside figma-use'), so conflict risk is minimal.
