Conciseness

The five-line body wastes nothing: no explanation of concepts Claude already knows, no padding — every line is a directive ('Read ... and execute it exactly as written', 'Then follow .agents/rules/cog.md') or a concrete conditional substitution rule. Lean and efficient throughout.

Actionability

Concrete file paths are given, but the body contains none of the actual executable guidance for the skill's stated purpose; the single directive delegates to '.claude/skills/product-ui-taste/SKILL.md', which is this very skill's own path (circular), and none of the referenced files ('.agents/rules/cog.md', '.agents/agents/<name>.md') exist in the bundle. High-level redirect with the specific steps to execute missing. Not 1 because it does instruct with explicit paths rather than merely describe.

Workflow Clarity

A rough sequence is present (read playbook → follow cog.md, plus a conditional substitution rule), but the primary step is incoherent as written — its target is the skill's own file — and no validation checkpoints exist anywhere in the body. Not 3 because the sequence cannot actually be followed from what is written: the playbook it depends on is either absent from the bundle or the file itself.

Progressive Disclosure

References are explicitly signaled but the body is a bare redirect with no overview content of its own, and the delegation chain extends two-plus levels (this SKILL.md → the playbook → '.claude/agents/<name>' workers → '.agents/agents/<name>.md'), with none of the referenced files present in the bundle, making navigation impossible. Not 1 because the body itself is short, organized into two clearly labeled parts, and its references are not buried; not 3 because the skill provides no overview to organize and the chain dead-ends at absent files.

Specificity

Lists multiple specific concrete actions and comprehensive coverage: 'reads the surface, budgets the frame first, and ships dense interfaces that are correct at every edge case (overflow, long labels, empty/error/loading states, i18n expansion, keyboard/a11y)' across enumerated surfaces ('dashboards, data tables, forms, multi-step flows, settings, list/detail, app shells'). Not 4 because coverage spans both surface types and edge-case correctness with no meaningful gap in the product-UI domain.

Completeness

The 'what' is clear (anti-slop product-UI skill, house-system-first, edge-case-correct dense interfaces) and the 'when' is present via 'for PRODUCT UI - dashboards, data tables, forms...' plus the counterpart scoping ('The counterpart to taste-skill, which owns landing/portfolio/marketing'), which functions as explicit trigger guidance. Not 5 because there is no explicit 'Use when...' phrasing; the trigger conditions must be inferred from the surface enumeration and could be stated more directly.

Trigger Term Quality

Comprehensive natural terms users would actually say: 'dashboards', 'data tables', 'forms', 'multi-step flows', 'settings', 'app shells', plus design-system synonyms (Carbon/Polaris/Atlaskit/Fluent/Primer/Material3/Radix-shadcn/Ant) and scope-clarifying terms ('landing/portfolio/marketing'). Not 4 because it covers both lay surface names and framework-specific synonyms a user might name directly.

Distinctiveness Conflict Risk

Clear niche (product UI) with an explicitly drawn boundary against its closest sibling ('The counterpart to taste-skill, which owns landing/portfolio/marketing') and distinct design-system triggers. Not 4 because the one real overlap risk (the counterpart taste skill) is explicitly disambiguated in the description itself.
