85%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 instruction-only skill: a clear 7-step workflow with a blocking validation gate, concrete tool calls and file-naming conventions, and a clean one-level-deep reference structure with working links. Its only real flaws are a Pitfalls section that largely duplicates earlier sections and a couple of minor template/edge-case inconsistencies.
Suggestions
Trim the Pitfalls section to only the 1-2 pitfalls not already stated in Core Principles and Step 6 (data integrity, metaphor literalization), cutting the five restated items to save tokens.
Fix the outline template so the yaml fence contains actual YAML (use '#' headings or 'Illustration 1:' keys instead of '## Illustration 1' markdown inside the block).
Specify the recovery path when the auto-retry in Step 6 also fails (e.g., skip and report, or ask the user) so batch runs don't stall.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and table-driven with no explanation of concepts Claude already knows, but the Pitfalls section restates ~5 earlier points nearly verbatim (strip secrets ↔ Pitfall 2, prompt-file mandate ↔ Pitfall 4, URL download ↔ Pitfall 6, aspect ratios ↔ Pitfall 5, backend note ↔ Pitfall 7). Mostly efficient with a trimmable duplicated section — anchor 4, not 5, since that section costs meaningful tokens for emphasis only. | 4 / 5 |
Actionability | Guidance is highly concrete: exact output tree, `curl -sSL -o "{output-dir}/NN-{type}-{slug}.png" "{url}"`, explicit aspect-ratio enum mapping, slug/conflict rules, and per-step tool calls. Minor gaps keep it below fully copy-paste-ready: the outline template mixes markdown headers inside a yaml fence, and 'auto-retry once' gives no path for repeated failure — anchor 4. | 4 / 5 |
Workflow Clarity | Seven explicitly sequenced steps with a checklist, an explicit validation checkpoint ('BLOCKING: Every illustration must have a saved prompt file before any image is generated'), a failure feedback loop ('On generation failure, auto-retry once'), and ordered clarify-question rules with skip conditions. This batch operation has its validation gate present — matches anchor 5. | 5 / 5 |
Progressive Disclosure | SKILL.md is a lean overview; all detail lives in one-level-deep references (workflow.md, styles.md, style-presets.md, prompt-construction.md, usage.md — all verified to exist), each inline-linked with section anchors per step and summarized in a References table. Clear overview with well-signaled one-level references — anchor 5. | 5 / 5 |
