Conciseness

The body is dominated by dense, high-value spec tables (platform dimensions, repurposing maps) with minimal prose, assuming Claude's competence. Not score 5 because the intro's engagement/ROI justification ("Visual-first planning in content calendars improves engagement; cross-channel consistency and repurposing maximize ROI") and the 'When invoking' meta-instruction pad slightly; not score 3 because only minor trimming is needed.

Actionability

As an instruction-only skill it gives concrete, usable guidance: exact dimensions and aspect ratios per platform ("1080×1350 (4:5)", "1000×1500 (2:3)"), a specific workflow ("Design at largest needed size; export platform-specific crops"), and a defined four-part output format. Not score 5 because some guidance remains directional (e.g., 'Organize by campaign/theme; tag for reuse') without examples; not score 3 because the spec tables are directly copy-usable.

Workflow Clarity

A clear two-phase flow: a numbered Initial Assessment (context, channels, repurposing) followed by a defined Output Format (visual plan, specs, repurposing map, references). Not score 5 because the connection between assessment answers and which reference sections to apply is implicit rather than an explicit sequence; not score 3 because the assess-then-deliver flow is unambiguous and no risky operations require validation checkpoints.

Progressive Disclosure

No bundle files exist, and the body is well-organized into clearly headed sections with consistently bolded, clearly signaled cross-skill references ("See twitter-x-posts", "See image-optimization"). Not score 5 because the inline platform spec table (section 3) duplicates content that the referenced platform skills own, which is a minor organization gap; not score 3 because structure and navigation are solid throughout.

Specificity

Names the domain ("visual content (images, infographics, social post images)") and actions ("plan, create, or repurpose"), but these verbs are fairly generic and do not convey the skill's concrete deliverables like platform specs or repurposing maps. Not score 4 because the actions lack the concreteness of anchor-4 examples like 'Extracts text from PDF files, fills forms'; not score 2 because the domain and object types are clearly named.

Completeness

Explicitly answers both what ("plan, create, or repurpose visual content... across channels") and when ("When the user wants to..." plus "Also use when the user mentions" with a concrete trigger-phrase list). Not score 4 because the 'when' is as explicit and trigger-anchored as the anchor-5 example; the Pinterest boundary note adds further usage guidance.

Trigger Term Quality

Lists nine natural phrases users would say ("content images," "social media images," "infographic," "visual content," "post image," "image specs," "visual repurposing," "content visuals," "image for social post"). Not score 5 because common variants like "social media graphics," "graphic," or "thumbnail" are missing; not score 3 because coverage goes well beyond a few relevant keywords.

Distinctiveness Conflict Risk

The trigger list is specific to visual content planning and the description explicitly hands off Pinterest ("For Pinterest, use pinterest-posts"), showing boundary awareness. Not score 5 because triggers like "post image" and "infographic" still overlap with platform skills (twitter-x-posts, linkedin-posts) and image-optimization; not score 3 because the explicit handoff and niche phrasing keep conflict risk minor.
