Conciseness

The body is dense and table-driven with almost no explanation of concepts Claude already knows, e.g. the Quick Reference table and terse Design Rules. It is not a 5 because the <role> section contains trimmable filler ('Know chart types, when each works, and when it fails') and inline time-sensitive detail ('paradigm v4 post 2026-05-06') sits outside any legacy/deprecated section.

Actionability

Most guidance is executable: concrete Grep/Glob paths ('backend/src/modules/analytics/api/'), a runnable Bash audit command ('docker exec -t visionarias_client_dev npm ls ... | grep -iE "chart|recharts|..."'), MCP query templates, and WebSearch site: queries. It is not a 5 because several steps remain conversational directives rather than copy-paste-ready commands (e.g. HTML preview steps reference a template flow without full detail).

Workflow Clarity

The multi-mode workflow is clearly sequenced with explicit gates ('Gate: Do NOT proceed without knowing what data exists...'), validation phases (D4/P4), a user-confirmation feedback loop ('Gate: User confirms the proposal meets their need'), and an ambiguity fallback question in Mode Detection. This matches the top anchor for clear sequence with explicit validation and feedback loops.

Progressive Disclosure

Structure exists and existing references are clearly signaled ('Read references/chart-selection-guide.md', 'Load references/viz-spec-template.md'), but navigation is incomplete: the body cites 'references/data-viz-conventions.md' which does not exist in the bundle, and the provided 'references/metrics-map.md' is never referenced from SKILL.md. This fits 'some structure but could be better organized' better than the minor-gaps anchor at 4.

Specificity

"Creates bar/line charts, renders data tables, aggregates KPI metrics, builds filterable dashboard layouts, and generates HTML previews for concept validation" lists five concrete actions with comprehensive domain coverage, matching the anchor for multiple specific concrete actions. It does not fall to 4 because coverage spans creation, aggregation, layout, and preview generation without notable gaps.

Completeness

Both 'what' ("Creates bar/line charts, renders data tables, aggregates KPI metrics, builds filterable dashboard layouts, and generates HTML previews") and 'when' ("Use when building data-heavy screens, analytics dashboards, metric visualizations, or inline charts for Copilot" plus an explicit Triggers list) are clearly and explicitly stated with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

The explicit "Triggers:" list covers natural bilingual terms including colloquial phrases users actually say ('muestra los datos', 'cómo van los números'), 'dashboard', 'gráfico', 'chart', 'KPI'. It stops short of 5 because common variations like 'tabla', 'graph', 'trend', or 'sales report' are missing, leaving a few natural terms uncovered.

Distinctiveness Conflict Risk

The domain (data-heavy screens, dashboards, KPI visualizations, Copilot inline charts) is a clear niche, but broad triggers like 'chart', 'analytics', and 'dashboard' create minor overlap risk with a general charting/dataviz skill. It is mostly distinct rather than fully distinct, so it fits the anchor at 4 rather than 5.
