78%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 skill body is maximally concise and appropriately structured for a simple single-purpose skill, with an explicit pre-return validation checkpoint. Its main weakness is actionability: it states what to verify but gives no concrete commands (e.g., an ffprobe invocation) or failure-handling guidance.
Suggestions
Add one concrete verification command, e.g. `ffprobe -v error -show_entries format=duration,size -show_entries stream=width,height output.mp4`, so the 'verify dimensions, duration, and output size' directive is executable.
Add a one-line failure-handling step (e.g., 'If verification fails, regenerate with corrected parameters before returning') to close the feedback loop and raise workflow clarity.
Briefly name the creation path (e.g., a minimal ffmpeg/Python invocation or the preferred tool per task) so the 'write generated media' directive has a concrete starting point.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is two lean sentences ('Write generated media inside the current sandbox workspace. Verify dimensions, duration, and output size before returning the result.') with zero padding and no explanation of concepts Claude already knows. Every token earns its place, matching the anchor-5 example of lean, competence-assuming content. | 5 / 5 |
Actionability | There is concrete guidance — a specific write location ('inside the current sandbox workspace') and specific verification criteria ('dimensions, duration, and output size') — but no executable commands or code (e.g., no ffprobe example, no creation commands). This matches anchor 3 ('some concrete guidance but incomplete; missing key details'); it is above anchor 2 because the directives are specific rather than high-level hints, and below anchor 4 because nothing copy-paste executable is provided. | 3 / 5 |
Workflow Clarity | The sequence (generate media -> write to workspace -> verify -> return) is clear and includes an explicit validation checkpoint ('Verify dimensions, duration, and output size before returning the result'), matching anchor 4 ('clear sequence with most checkpoints present; minor validation gaps'). It falls short of 5 because there is no feedback loop or guidance on what to do when verification fails. | 4 / 5 |
Progressive Disclosure | This is an under-50-line simple skill with no bundle files (references/, scripts/, assets/ are absent) and no content that belongs in separate files; everything is appropriately in SKILL.md and trivially navigable. Per the rubric's simple-skills scoring note, this warrants a 5. | 5 / 5 |
