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.
A well-structured, actionable skill body with clear sequencing, validation checkpoints, and clean progressive disclosure to a single bundled reference. The main improvement is reducing inline table duplication and adding an explicit retry loop for verification failures.
Suggestions
Trim the inline size and style tables to a few representative rows plus a pointer to the reference to reduce token duplication.
Add a short copy-paste HTML/CSS banner scaffold to make Step 3 fully executable rather than described.
Insert an explicit 'if verification fails, fix and re-verify before proceeding' loop in Step 4 to match the strongest workflow-clarity anchor.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly lean and assumes Claude's competence, but the inline Banner Size Quick Reference and Top-10 Styles tables duplicate content already in the reference file and could be trimmed to pointers. | 4 / 5 |
Actionability | Concrete numeric guidance (exact dimensions, 70-80% safe zone, 4.5:1 contrast, kebab-case path convention) is highly actionable, though no copy-paste HTML/CSS banner template is provided. | 4 / 5 |
Workflow Clarity | A clear five-step sequence with explicit verification in Step 4 (pixel dims, safe-zone crop, font loading, quality) and a file-size feedback loop; minor gap is the lack of an explicit re-validate-and-retry loop for design verification failures. | 4 / 5 |
Progressive Disclosure | A single real, well-signaled one-level-deep reference (references/banner-sizes-and-styles.md) is referenced repeatedly ("Full reference:", "Full 22 styles:"), with summaries inline and full detail split out cleanly. | 5 / 5 |
