Names the domain (videos) and some actions (extract frames, short clips) with a specific tool (ffmpeg), but doesn't list more comprehensive capabilities like format conversion, time range selection, or output options.

Describes what the skill does but has no explicit 'Use when...' clause or equivalent trigger guidance, which per the rubric caps completeness at 2, and the 'what' is also only moderately detailed, placing this at 1-2. Given the missing 'when' clause entirely, this is capped and leans toward 1.

Includes good natural keywords like 'frames', 'clips', 'videos', and 'ffmpeg', but misses common variations users might say such as 'screenshot from video', 'thumbnail', 'gif', 'extract scene', or file extensions like '.mp4', '.mov'.

The combination of video frame/clip extraction with ffmpeg is a clear, distinct niche that is unlikely to conflict with other skills. The specificity of the tool (ffmpeg) and the action (extracting frames/clips from videos) makes it highly distinguishable.

Very lean and efficient. No unnecessary explanations of what ffmpeg is or how video formats work. Every line serves a purpose.

Provides concrete, copy-paste ready bash commands with clear flag usage (--time, --out) and practical examples at different use cases (first frame vs. timestamp).

This is a simple, single-purpose skill (extract a frame). The single action is unambiguous with clear examples. No multi-step process or destructive operations requiring validation checkpoints.

For a simple skill under 50 lines with no need for external references, the content is well-organized with a quick start section and concise notes. No bundle files are needed for this scope.
