Conciseness

The body is lean and every token earns its place: it skips all concept explanation and spends its lines on tool call signatures, sequencing rules, and non-obvious backend facts ('normalizes one bounded PNG', 'Only save_artifact makes the infographic durable. Sandbox files and provider URLs are transient.'). This matches the anchor for assuming Claude's competence with no padding.

Actionability

Concrete call signatures for execute, verify_artifact, and save_artifact with exact parameter names give mostly executable guidance, but placeholders like '<slug>', 'title="..."', and 'repair_findings=[...]' leave minor gaps versus copy-paste-ready examples. This fits 'concrete code or commands with minor gaps' rather than the fully executable anchor.

Workflow Clarity

The sequence — author the contract, generate once, verify, repair exactly once with the same inputs, verify again, then save — is explicit, with a dedicated validation checkpoint, a bounded feedback loop, and an explicit stop condition ('If any blocker remains, stop and explain it. Do not loop or save.'). This matches the anchor for clear sequencing with explicit validation and error-recovery loops.

Progressive Disclosure

This is a simple, single-purpose skill with no bundle files and no content that belongs in a separate file; the short body is organized into well-signaled H2 sections (Author, Generate, Verify/repair/save, Revisions) that make navigation trivial. Per the rubric's simple-skill note, well-organized sections alone merit the top score.

Specificity

The description names the domain and one concrete action — 'Create a factual, image-model-generated infographic' — but stops there; it omits the skill's other actions (authoring the markdown contract, verifying, saving, revising), so it matches the anchor for 1-2 concrete actions without comprehensive coverage. It is more informative than the generic anchor-2 example ('Processes PDF files') but well short of anchor 4's several specific actions.

Completeness

The 'what' is clearly stated ('Create a factual, image-model-generated infographic through the unified artifact workflow'), but there is no 'Use when...' clause or equivalent trigger guidance anywhere. Per the judging guidelines, a missing trigger clause caps completeness at 3.

Trigger Term Quality

'infographic' is a strong, natural keyword users would actually say, but it is the only one — no synonyms, variations, or trigger phrases accompany it. This matches the anchor for some relevant keywords while missing common variations, above generic-only (anchor 2) but below good coverage (anchor 4).

Distinctiveness Conflict Risk

'infographic' carves out a clear niche with only minor overlap risk against closely related image-generation or visualization skills. However, unlike the anchor-5 example, no explicit distinct triggers are stated, so it fits 'mostly distinct; minor overlap risk' rather than 'clear niche with distinct triggers'.
