Quick Review

Excellent skill with comprehensive documentation. The description clearly explains when and how to invoke the skill, with detailed command examples, requirements, and error handling guidance. The structure is well-organized with a clear overview, usage patterns, and appropriate references to external files for deep-dive content. Task knowledge is thorough, covering installation, command options, batch processing, validation, metrics explanation, and troubleshooting. Novelty is moderate: while video comparison with quality metrics is useful and would consume many tokens for a CLI agent to implement from scratch, the core functionality (FFmpeg wrapper with HTML report generation) is relatively straightforward. The skill provides clear value in automating a multi-step process (metadata extraction, frame comparison, metric calculation, report generation) that would otherwise require significant manual orchestration.
