Conciseness

The body is mostly operational guidance, but it includes unnecessary padding: the opening definition ('Infographics are visual representations of information, data, or knowledge...') that Claude already knows, the 'Smart Iteration Benefits' checkmark marketing bullets, three near-identical --research CLI examples that differ only in --type, a motivational closing line, and a marginal 'Integration with Other Skills' section. This fits anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened') better than anchor 2, since the bulk is dense and non-redundant.

Actionability

The CLI examples are fully executable copy-paste commands covering the common cases (types, styles, palettes, research, doc-type thresholds), and troubleshooting is framed as concrete problem/solution pairs. It falls short of anchor 5 because key output artifacts are only vaguely specified: the review log's file path is never given ('Check the review log for scores', 'Inspect the critique') and the versioned PNG naming scheme is not shown, whereas '{name}_research.json' is.

Workflow Clarity

The generate-review-refine loop is explicitly sequenced (numbered 'What happens behind the scenes' steps with stop conditions), validation is built in via Gemini review against per-document-type thresholds, a feedback loop exists ('Retain content and source context, refine the prompt, regenerate'), failure handling is specified ('stop on API failure and keep the latest saved draft'), and before/after checklists are provided. This matches anchor 5 exactly.

Progressive Disclosure

Detailed material is pushed one level deep into real, existing reference files (infographic_type_catalog.md, infographic_types.md, iterative_refinement.md, design_principles.md, color_palettes.md), all cited with clear signals. It falls short of anchor 5 due to minor organization gaps: two overlapping references (infographic_type_catalog.md and infographic_types.md) are cited for the same type information, and the API/model contract section carries endpoint-level detail inline rather than in a reference.

Specificity

The description states concrete actions ('Creates and reviews infographics with Nano Banana 2 via OpenRouter') and enumerates concrete outputs and features ('statistical summaries, timelines, comparisons, processes', 'ten layouts, eight style presets, reference images, and accessible palette starting points'). It lists several specific capabilities with only minor gaps, fitting anchor 4 rather than 5 because the core actions are limited to create/review with the rest being feature enumeration.

Completeness

It explicitly answers both questions: what ('Creates and reviews infographics with Nano Banana 2 via OpenRouter') and when ('Use for statistical summaries, timelines, comparisons, processes, and visual explanations with supplied data or optional Sonar research') with concrete trigger phrases. This matches anchor 5 exactly; anchor 4 would require the 'when' clause to be less explicit than the direct 'Use for...' list given here.

Trigger Term Quality

'infographics', 'statistical summaries', 'timelines', 'comparisons', 'processes', and 'visual explanations' are phrases users would naturally say when they need this skill. Coverage is good but a few common variations are missing (e.g. 'chart', 'diagram', 'poster', 'data visualization'), so it fits anchor 4 rather than anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

'Infographics' names a clear niche with its own distinct trigger vocabulary, so it is mostly distinguishable. However, triggers like 'statistical summaries' and 'visual explanations' have minor overlap risk with general charting/dataviz skills, fitting anchor 4 ('mostly distinct; minor overlap risk') rather than anchor 5's minimal conflict risk.
