Conciseness

Mostly lean with no padding and no re-explanation of basics: every section is a template, checklist, BAD/GOOD example, or command. Minor trimmable instances remain — the H1 subtitle ("Strategic architecture principles for boundaries, dependencies, and layered system design") duplicates the frontmatter description, and several 'WHY' paragraphs (e.g., why circular dependencies prevent independent testing/deployment) restate consequences Claude could infer.

Actionability

Concrete and mostly executable throughout — complete TypeScript port/adapter and use-case templates, an ADR template, and BAD/GOOD examples covering the common cases. Minor gaps: the first rg pattern ("import.*infrastructure.*from.*domain|import.*adapter.*from.*entity") mostly matches the allowed inward direction rather than actual violations, and "nx graph" presumes an Nx monorepo with no fallback.

Workflow Clarity

Six clearly sequenced steps, each declaring an explicit "Output:" artifact, with a checklist at Step 2 — strong checkpoints. No explicit validation/feedback loop though: after refactoring a violation, the workflow never re-runs the dependency checks to confirm resolution, which the top anchor requires.

Progressive Disclosure

Excellent one-level-deep structure: 28 categorized reference files under thematic groups (Dependencies, Entities, Use Cases, Adapters, Frameworks), all verified present on disk. Two minor organization gaps keep it below the top anchor: references/comp-common-reuse.md is an orphan (never linked, undiscoverable), and the three external links sit unlabeled directly beneath the 'Frameworks' bullet, appearing to belong to it.

Specificity

Names the domain and lists three concrete actions — "define layer boundaries, identify dependency violations, and structure domain vs infrastructure code" — but omits capabilities the body actually covers (use-case design, adapter placement, boundary documentation), leaving minor gaps in coverage rather than the comprehensiveness of the top anchor.

Completeness

Clearly and explicitly answers both 'what' ("Apply Clean Architecture principles to define layer boundaries, identify dependency violations, and structure domain vs infrastructure code") and 'when' ("Use when designing service boundaries... or resolving dependency inversion and circular dependency issues") with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Trigger coverage is comprehensive and includes synonyms: "designing service boundaries", "separating business logic from infrastructure", "hexagonal/onion/ports-and-adapters architecture" (all three naming variants of the style), "structing module layout", and "resolving dependency inversion and circular dependency issues" — all natural phrases a user would say when needing this skill.

Distinctiveness Conflict Risk

A clear niche (layered/clean architecture design) with mostly distinct triggers, but "resolving dependency inversion" overlaps with the DIP coverage of a closely related class-design/SOLID skill — a user asking about the dependency inversion principle alone could plausibly trigger either skill, so the risk is minor but not minimal.
