68%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 well-structured and highly actionable with concrete commands and selectors throughout. Its main gap is the missing verify-before-cleanup checkpoint in a workflow that deletes temporary files.
Suggestions
Add a validation step before cleanup: verify each output .webp exists (and is non-empty) before deleting its source PNG, and only delete the PNGs whose conversion succeeded.
Provide a complete copy-paste Playwright .mjs scaffold (launch, addCookies, goto, screenshot) instead of listing the steps as prose, to lift actionability to fully executable.
Consider moving the CodeMirror interaction and UI navigation button lists into a references/ file, keeping SKILL.md as a tighter overview.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly lean with executable commands and no concept over-explanation, but a few justifications like "An open overlay blocks clicks on other elements" could be trimmed. | 4 / 5 |
Actionability | Concrete curl, JSON auth state, CSS selectors, keyboard commands, and cwebp invocations are provided, but the Playwright screenshot script is given as numbered steps and config values rather than full copy-paste code. | 4 / 5 |
Workflow Clarity | The Prerequisites → Authentication → Screenshots → Image Processing sequence is clear and numbered, but the destructive "Clean up temporary PNG files after conversion" step lacks a validation checkpoint confirming the WebP output succeeded, which caps this at 3 per the rubric. | 3 / 5 |
Progressive Disclosure | No bundle files exist and sections are well-organized with no nested references, but at 97 lines the dense inline CodeMirror/UI navigation detail sits just above the simple-skill threshold where it could warrant a reference file. | 4 / 5 |
