Conciseness

The body is efficient and procedural — checklists, a navigation-tier diagram, and a decision-flow block with no padded exposition. Minor trimmable redundancy: the no-custom-Colors rule is stated three times, and 'bar for comparison, line for trends' re-teaches knowledge Claude already has, keeping it just below the lean 5 anchor.

Actionability

For an instruction-only skill the guidance is fully executable: exact copy operations ('Copy the template from assets/1_information_architecture.md to spec/1_information_architecture.md at the project root, fill in the placeholders, and save it BEFORE proceeding'), a concrete decision flow mapping data shape to named interaction patterns, and precise spec-file requirements. It exceeds the 4 anchor's 'minor gaps' level.

Workflow Clarity

Steps 1-3 are explicitly ordered ('Run Steps 1-3 in order; each step depends on the prior'), each gated by a validation checklist, with a progress tracker and explicit handling of partial contexts ('User has wireframes → Validate Step 1 decisions, then proceed from Step 2'). This matches the 5 anchor's explicit validation steps and checkpoints.

Progressive Disclosure

The body is a clear overview with well-signaled, one-level-deep references: three reference files, three asset templates, and three sibling skills, all verified to exist, plus a closing 'Reference Files' table with a 'When to Load' column. This is the 5 anchor's structure exactly.

Specificity

The description lists several concrete actions — 'Enforces a 3-step workflow (requirements, layout, visualization) before implementation' and an explicit handoff ('use the dashboard-build skill after completing Steps 1-3'). It stops short of the 5 anchor's comprehensive artifact-level action list, and exceeds the 3 anchor's 1-2 action scope.

Completeness

Both what and when are explicit: 'Enforces a 3-step workflow (requirements, layout, visualization) before implementation' answers what, and 'Use this skill first when the user wants to design or plan a dashboard... Activate when the user asks to create, design, or plan a dashboard' gives concrete trigger phrases, matching the 5 anchor.

Trigger Term Quality

Good natural keyword coverage: 'design or plan a dashboard', 'create, design, or plan a dashboard', and 'Vizro dashboards' are phrases users would actually say. A few natural variations ('build a dashboard', 'report', 'data app') are missing, keeping it below the comprehensive 5 anchor.

Distinctiveness Conflict Risk

'especially Vizro dashboards' and the explicit 'For implementation, use the dashboard-build skill' boundary carve a clear niche and reduce conflict risk. 'Design a dashboard' still overlaps with generic chart-selection or visualization skills, so it sits at mostly-distinct rather than the 5 anchor's minimal conflict.
