Conciseness

Efficient and dense: routing, per-path read lists, and structure specs with no explanation of concepts Claude already knows. Not 5 because the 'Design philosophy' section repeats guidance already stated in the Plan path ('No time estimates', 'One idea per viewport', whitespace advice) and the delivery section re-explains the gate already given per-path reference pointers; not 3 because the redundancy is minor and everything else earns its tokens.

Actionability

Fully actionable for an instruction-only skill: copy-paste commands ('plannotator annotate <file> --gate', 'npx skills add nicobailon/visual-explainer -g --yes'), exact check paths, enumerated failure signatures ('aria-roledescription="error"', 'Syntax error in text'), and concrete component specs (NEW/MOD/DEL badges, HIGH/MED/LOW severity badges, three risk tiers). Not 4 because no material executable gap remains in the body — the only command-less step (Mermaid rendering) is a competence assumption, and pattern details are correctly deferred to real reference files.

Workflow Clarity

Clear three-way routing by content type, numbered 'Before generating, read' sequences per path, an explicit validation hard gate with a feedback loop ('Fix the diagram or theme configuration and rerun both palettes until every SVG passes'), additional zoom/pan legibility checks for diagram shells, and a consent-gated install flow with defined stop conditions. Not 4 because validation checkpoints and error-recovery loops are explicit rather than implicit, matching the top anchor.

Progressive Disclosure

The body is a clean overview routing to five real, one-level-deep reference files, each named with a numbered read list and a description of its contents; all referenced paths exist. Not 5 because the bundle's references/pr-components.md points to '../../plannotator-visual-plan/references/design-system.md', a cross-bundle path that does not resolve within this bundle and creates ambiguity with the local references/design-system.md the PR path already directs you to read; not 3 because the body's own structure, signaling, and content split are otherwise exemplary.

Specificity

Names the domain ('self-contained HTML visualizations with Plannotator theming') and one concrete action ('Generate'), plus a delegation behavior, but enumerates content types rather than distinct actions. Not 4 because it does not list several specific concrete actions (no build/render/theme/convert-style verb list); not 2 because the actions given are concrete, not generic.

Completeness

Explicitly answers both: what ('Generate self-contained HTML visualizations with Plannotator theming') and when ('Use for implementation plans, PR explainers, architecture diagrams, data tables, slide decks, and any visual explanation of technical concepts') with concrete trigger phrases. Not 4 because the 'when' clause is already explicit and enumerated with a catch-all, leaving no specificity gap.

Trigger Term Quality

Good natural-term coverage: 'implementation plans, PR explainers, architecture diagrams, data tables, slide decks, and any visual explanation of technical concepts' — phrases users would actually say. Not 5 because it lacks synonyms and variations (e.g., 'presentations', 'infographics', 'explain this PR visually', file extensions); not 3 because common content-type triggers are well covered.

Distinctiveness Conflict Risk

Mostly distinct: the 'Plannotator theming' niche and the explicit routing statement ('Plans and PR explainers follow Plannotator's prescriptive approach; all other visual content delegates to nicobailon/visual-explainer') reduce conflict with the sibling skill. Not 5 because the broad catch-all 'any visual explanation of technical concepts' could still overlap generic visualization/diagramming skills; not 3 because the delegation boundary explicitly delineates the closest competitor.
