Content
70%Reviews 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 uses progressive disclosure effectively with a real one-level reference, but it leans slightly on marketing framing and keeps its executable examples in the reference rather than inline.
Suggestions
Trim the persuasive framing in the intro ("costs nothing to add", "lowest-effort high-impact... available today") to reduce padding and avoid duplication with the reference's Why It Matters section.
Include at least one inline copy-paste-ready HTML snippet for the LCP image in the body so the core action is executable without opening the reference.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly lean and assumes Claude's competence, but the intro carries mild marketing padding ("costs nothing to add", "lowest-effort high-impact performance optimisation available today") and partly duplicates the reference's Why-It-Matters content, so it could be tightened further. | 2 / 3 |
Actionability | Quick Reference and the Fix/Code Review sections give concrete, directive guidance ("Add fetchpriority=\"high\" to the LCP image", "Use fetchpriority=\"high\" on <link rel=\"preload\">"), but executable code blocks are delegated to references/rule.md rather than present inline, keeping it short of fully copy-paste-ready. | 2 / 3 |
Workflow Clarity | For this simple single-purpose skill the Check -> Fix -> Explain -> Code Review sequence makes the single action (add fetchpriority attributes) unambiguous, with the Check step serving as an explicit validation checkpoint before fixing. | 3 / 3 |
Progressive Disclosure | The body is a concise overview that points to a single, clearly signaled one-level-deep reference (references/rule.md, which exists and does not nest further) for full details, code, and framework guidance. | 3 / 3 |
