Conciseness

The body is efficient and dense with concrete tables, timings, and checklists, assuming Claude's competence. Minor trimmable padding exists: the persona rhetoric ("You are a video producer. Not a slideshow maker. Every frame has a job.") and the MCP-fallback information repeated across step 1, the mode table, and the Output Artifacts section.

Actionability

Concrete, specific guidance throughout — exact story arcs with per-scene durations, 1920x1080 viewport, exact spring easing curve, a defined artifact tree, and a build.sh pipeline description. However, the actual playwright/edge-tts/ffmpeg commands are sketched ('playwright screenshot each HTML scene') rather than given as copy-paste-ready commands, leaving minor gaps.

Workflow Clarity

A clear four-step sequence (mode selection with tool verification and fallbacks → story structure → scene design → narration) followed by a defined artifact spec, with a Quality Checklist serving as validation checkpoints. The checklist lacks an explicit validate→fix→re-check feedback loop, keeping it short of the full-checkpoint anchor.

Progressive Disclosure

The ~105-line body is well-sectioned, and design-system detail is appropriately split into a real, clearly signaled, one-level-deep reference (references/scene-design-system.md), which itself contains no further nested references. Cross-references to related skills are clearly labeled. This matches 'Clear overview with well-signaled one-level-deep references; content appropriately split'.

Specificity

The description names the domain and a single composite action — "Orchestrates playwright, ffmpeg, and edge-tts MCPs to produce polished video content" — with concrete tool names, but does not enumerate several distinct actions (e.g., rendering scene HTML, generating narration, compositing with transitions). It matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'.

Completeness

Both sides are explicitly present: "Use when the user asks to create a demo video, product walkthrough..." answers 'when' with concrete triggers, and "Orchestrates playwright, ffmpeg, and edge-tts MCPs to produce polished video content" answers 'what'. However, the 'what' clause is thin and slightly vague ("polished video content"), so it does not clearly reach the fully-explicit both-sides anchor.

Trigger Term Quality

Phrases like "demo video", "product walkthrough", "feature showcase", "marketing video", "GIF", and "screenshots" are natural terms users would say, giving good coverage. A few common variations are missing (e.g., "promo video", "screen recording", "tutorial video"), so it falls short of the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

The video-production-from-screenshots niche is mostly distinct with specific triggers, but terms like "animated presentation" and "GIF" create minor overlap risk with presentation-creation and image/animation skills. It fits 'Mostly distinct; minor overlap risk with closely related skills'.
