Names the domain (TikTok marketing) and some actions ('viral content creation, algorithm optimization, community building'), but these are broad categories rather than concrete, specific actions like 'write video scripts' or 'analyze hashtag performance'.

Describes what it does at a high level but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. Per the rubric, a missing 'Use when...' clause caps completeness at 2, and the 'what' is also vague, warranting a 1.

Includes relevant keywords like 'TikTok', 'viral content', 'algorithm', and 'brand growth', but misses common user variations like 'short-form video', 'TikTok strategy', 'hashtags', 'trending sounds', 'Reels', or 'social media marketing'.

The TikTok focus provides some distinctiveness from general social media skills, but terms like 'community building' and 'brand growth' are generic enough to overlap with other social media or marketing skills.

Extremely verbose with extensive padding. Explains general marketing concepts Claude already knows (what engagement rate is, what nano/micro influencers are, basic ad formats). Success metrics are duplicated across sections. The 'Identity & Memory' and 'Communication Style' sections describe persona traits rather than providing actionable instructions. Nearly every section could be cut by 60%+ without losing useful information.

Almost entirely abstract and descriptive rather than instructive. No concrete code, commands, templates, or executable examples. Statements like 'Hook in 3 Seconds' and 'Viral Formula Application' are vague directives without showing what a hook looks like or providing actual content templates. The skill describes what to do at a high level but never shows how to do it with specific, copy-paste-ready outputs.

The four-phase workflow provides a reasonable sequence of steps, but lacks any validation checkpoints, feedback loops, or concrete decision criteria. Steps are listed as bullet points of concepts rather than actionable procedures. There's no mechanism to verify whether a phase was completed successfully before moving to the next.

Monolithic wall of text with no references to external files. All content is inline in a single long document with significant redundancy (success metrics appear twice, content pillars mentioned in multiple sections). No navigation aids, no links to detailed guides, and the 'Advanced Capabilities' section largely repeats earlier content with slightly more detail.
