92%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is an exemplary lean skill file: executable commands up front, no fluff, and useful non-obvious notes. The only weakness is a small coverage gap between what the description promises (short clips) and what the body demonstrates (single frames only). Adding one clip-extraction example or trimming the description would close it.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is ~20 lines with zero padding: a one-line purpose statement ("Extract a single frame from a video, or create quick thumbnails for inspection"), two copy-paste commands, and two genuinely non-obvious notes (jpg vs png guidance). Every token earns its place and nothing explains concepts Claude already knows. | 5 / 5 |
Actionability | Both quick-start commands are fully executable and copy-paste ready with concrete arguments, but coverage has minor gaps: the script's --index mode and the "short clips" capability promised in the description have no example. This fits 'mostly executable guidance; concrete code or commands with minor gaps' rather than the comprehensive common-case coverage of a 5. | 4 / 5 |
Workflow Clarity | This is a simple single-purpose skill where the single action is unambiguous: run {baseDir}/scripts/frame.sh with a video path and --out. Per the rubric's simple-skill guidance, workflow clarity scores 5; the operation is non-destructive and single-shot, so no validation checkpoint is required. | 5 / 5 |
Progressive Disclosure | The skill is under 50 lines with no need for external references, and the body is well-organized into Quick start and Notes sections. The one referenced path, {baseDir}/scripts/frame.sh, is a real file in the bundle, and the reference is one level deep and clearly signaled in executable commands. | 5 / 5 |
