Conciseness

The body is ~45 lines of terse imperative steps with zero concept explanations, no padding, and even the validation step is a one-liner ("npx tsc --noEmit && npx vite build"). Every token earns its place and it fully assumes Claude's competence.

Actionability

It provides a concrete directory tree, an exact validation command, and specific stack guidance (React Query, React.lazy() + Suspense). However, "Use `@builder` to create bottom-up" and "Register the route in the router" omit the specific mechanics/file locations, and the index.ts block is comments only — minor gaps that keep it below fully copy-paste ready.

Workflow Clarity

A clear numbered 1–7 sequence includes a user-input checkpoint (step 4) and an explicit final validation command. It falls short of the top anchor because there is no feedback loop (fix-and-re-validate on failure) and validation appears only once at the end.

Progressive Disclosure

The skill is under 50 lines with no bundle files, is well organized into steps, and properly offloads detailed conventions to docs/ARCHITECTURE.md with specific section numbers (2, 3 and 4) — exactly the one-level-deep reference pattern the rubric rewards for simple skills.

Specificity

The description enumerates six concrete deliverables ("service, adapter, types, state, components, and tests") but relies on a single action verb ("creating"), so it lists several specific elements with minor gaps rather than the comprehensive multi-action coverage of the top anchor.

Completeness

It explicitly answers both parts: "Use when creating a new feature module" gives the when, and the layer enumeration gives the what. However, the what is implicit (the skill scaffolds these layers) and the when lacks concrete trigger variations, so it does not clearly reach the fully explicit top anchor.

Trigger Term Quality

The only natural trigger phrase is "creating a new feature module"; the layer names describe the deliverable rather than phrases a user would say, and common variations like "scaffold", "add", or "generate a module" are missing. This matches "some relevant keywords but missing common variations or synonyms" better than the good-coverage anchor above it.

Distinctiveness Conflict Risk

The specific layered-architecture enumeration ("service, adapter, types, state, components, and tests") carves a distinct niche, but a generic component- or feature-creation skill could still claim overlapping triggers, matching "mostly distinct; minor overlap risk with closely related skills".
