Lists multiple specific concrete actions and capabilities: campaign types analysis, creative quality evaluation, audience targeting, measurement, VAC→Demand Gen migration, Shorts creative requirements, CTV shoppable ads, and evaluation across six named ad formats.

Clearly answers both 'what' (YouTube Ads analysis covering campaign types, creative quality, audience targeting, measurement, specific format evaluation, migration guidance) and 'when' with an explicit 'Use when user says...' clause listing specific trigger terms.

Excellent coverage of natural terms users would say: 'YouTube Ads', 'video ads', 'pre-roll', 'bumper ads', 'YouTube campaign', 'Shorts ads', 'CTV ads'. These are all terms a user would naturally use when seeking help with YouTube advertising.

Highly distinctive with a clear niche in YouTube-specific advertising. The mention of specific formats (skippable, non-skippable, bumper, Shorts, Demand Gen, CTV), platform-specific migrations (VAC→Demand Gen), and YouTube-specific trigger terms make it very unlikely to conflict with general advertising or other platform-specific skills.

The skill is generally information-dense and avoids explaining basic concepts Claude would know, but includes some unnecessary detail like the Facebook muted-video stat, case study narratives (DoorDash, Triscuit), and marketing-speak that doesn't add actionable value. The content could be tightened by ~20% without losing utility.

The skill provides highly concrete, specific guidance: exact benchmarks with numbers, specific check IDs (G-DG1, G-CTV1), precise format specs (9:16, 1080x1920), clear evaluation criteria per campaign type, a metrics table with benchmarks, and a quick wins table with time estimates. The references to external files for scoring algorithms and benchmarks are appropriately delegated.

The Process section has a clear 10-step sequence with two explicit validation checkpoints (steps 6 and 9), a migration check (step 7), and clear ordering from data collection through report generation. The quick wins table provides a secondary lightweight workflow. Destructive operations aren't relevant here, but the validation steps for confirming active campaigns and campaign type identification are appropriate.

The skill appropriately references four external files (google-audit.md, platform-specs.md, benchmarks.md, scoring-system.md) for detailed specifications, keeping the main skill as an operational overview. References are one level deep and clearly signaled. The content is well-organized with logical sections and a clear hierarchy from process to assessment to output.
