Conciseness

The body is entirely functional — a scope resolution line, 16 executable checks, and an output format spec — with no explanation of concepts Claude already knows and no padding. Every token earns its place, matching the 'Lean and efficient' anchor rather than score 4, which anticipates trimmable over-explanation.

Actionability

All 16 checks are concrete, executable bash commands that are essentially copy-paste ready. Not score 5 due to minor executable gaps: check 16's 'find ... -name "+page.ts" -o -name "+page.server.ts"' lacks parentheses (find's implicit -print binds only to the last predicate, silently skipping +page.ts files), and checks 10/13 output bare 'wc -l' counts with no guidance on interpreting them as pass/fail.

Workflow Clarity

The sequence is unambiguous — run the checks, resolve scope ('if empty, validate all src/lib/modules/'), fill in the summary table, compute the overall score. Not score 5 because there is no guidance on what to do with FAIL results or how to fill the table for count-based checks; the workflow cap of 3 does not apply since the skill is itself a read-only validation checker, not a destructive or unvalidated batch operation.

Progressive Disclosure

Good structure for a self-contained skill: a clear heading, explicit scope, a single cohesive check script, and a defined output format. Not score 5 because the body exceeds 50 lines and the 16 checks could be grouped (Svelte 4 migration vs SvelteKit 1 vs general hygiene) or moved to a scripts/ file to slim the overview.

Specificity

Names the domain ('checking if code follows ARCHITECTURE.md patterns') and one concrete action ('runs automated conformance checks'), but does not enumerate what the conformance checks actually cover. It matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive' rather than score 4, which requires several specific actions.

Completeness

Both parts are explicit: 'what' via 'runs automated conformance checks' and 'when' via the 'Use when checking if code follows ARCHITECTURE.md patterns' clause. Not score 5 because the when-clause provides only a single trigger phrase without concrete variations or synonyms; not score 3 because neither part is missing or merely implied.

Trigger Term Quality

Relevant keywords like 'architecture', 'patterns', and 'conformance' are present, but common natural variations users would say ('architecture review', 'standards', 'does this follow the architecture doc') are missing. This fits 'Some relevant keywords but missing common variations or synonyms' rather than score 4's 'Good keyword coverage'.

Distinctiveness Conflict Risk

The description is anchored to a specific artifact ('ARCHITECTURE.md') and a distinct purpose (automated conformance checking), giving it a clear niche. Not score 5 because it could still overlap with generic code-review or architecture-review skills.
