Conciseness

The body is a lean catalog — two headers, three one-line usage steps, and two minimal entries (Name/Import/Source) with no explanations of concepts Claude already knows and no padding. This matches the score-5 anchor 'Lean and efficient; assumes Claude's competence; every token earns its place'; there is nothing to trim, so 4 is excluded.

Actionability

Each entry gives a concrete, copy-paste-ready import statement and an exact source path (e.g., 'import { useNavigateFolder } from "webiny/admin/aco"' plus '@webiny/app-aco/hooks/useNavigateFolder.ts'), but there are no examples of how to call the hooks or what they return — the skill delegates that entirely to reading the source. This matches score 4 ('Mostly executable guidance; concrete code or commands with minor gaps'); it cannot be 5 because the common usage cases are not covered inline, and not 3 because the guidance given is fully executable, not pseudocode.

Workflow Clarity

This is a simple, single-purpose skill with an unambiguous three-step sequence: find the abstraction, read the listed source file, import using the given template, with the imperative 'You MUST read the source file' acting as an explicit checkpoint. Per the simple-skill guideline, a single unambiguous action warrants a 5; not 4 because no step is ambiguous or missing a checkpoint.

Progressive Disclosure

The skill is under 50 lines, needs no external references, and is well-organized into 'How to Use' and 'Abstractions' sections with each entry pointing one level deep to its source file — the entire document is an overview. This matches both the under-50-lines guideline and the score-5 anchor 'Clear overview with well-signaled one-level-deep references; easy navigation'; no bundle files exist to penalize structure.

Specificity

The description names a domain ("admin/aco") but includes zero concrete actions — it only states "2 abstractions" without saying what any of them do. It is not entirely vague since the domain is identifiable, matching the anchor 'Names the domain but actions are minimal or generic'; it cannot be 3 because no 1-2 concrete actions are listed, and not 1 because the domain is specifically named rather than pure abstract language.

Completeness

A vague 'what' is present (a catalog of 2 abstractions in admin/aco) but the 'when' is entirely missing — no 'Use when...' clause or equivalent trigger guidance. This matches the score-2 anchor 'Has a vague what and no when'; it cannot be 3 because the 'what' never states any actions performed, and cannot be 1 because the domain and content type are at least identified.

Trigger Term Quality

"admin/aco — 2 abstractions" contains only internal technical jargon with no natural keywords a user would say (no mention of navigation, folders, records, Webiny, or hooks). This matches the score-1 anchor 'No natural keywords; only technical jargon'; it cannot be 2 because even one generic natural keyword is absent.

Distinctiveness Conflict Risk

"admin/aco" is a specific Webiny module path, giving it a somewhat distinct niche, but the description says nothing else, so it could still overlap with other Webiny admin catalog skills. This matches the score-3 anchor 'Somewhat specific but could still overlap'; not 4 because no distinct trigger phrases distinguish it from sibling catalog skills, not 2 because the technical path is far more specific than 'document files'-level breadth.
