100%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: concise, fully executable, single-action clear, with implementation correctly externalized to a bundled script. Nothing material is missing for a single-purpose ffmpeg frame extractor.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean — a one-line capability statement, two copy-paste commands, and three terse notes — with no padding or explanation of concepts Claude already knows; every token earns its place. | 5 / 5 |
Actionability | It gives fully executable, copy-paste-ready commands referencing the real frame.sh script with concrete args and outputs, covering the two common cases (first frame, frame at a timestamp). | 5 / 5 |
Workflow Clarity | This is a simple single-purpose skill where the single action (run frame.sh with args) is unambiguous; the script itself validates inputs (file-exists, required --out), and frame extraction is neither destructive nor batch, so the simple-skill exception applies. | 5 / 5 |
Progressive Disclosure | Under 50 lines with well-organized sections (Quick start, Notes) and the implementation correctly split into a one-level-deep bundled script (scripts/frame.sh) referenced via {baseDir}; no further references are needed. | 5 / 5 |
