Conciseness

The body is pure payload — one 14-check bash block plus a three-line output spec ('Produce a summary table ... Overall score: X/14 checks passing.') — with zero conceptual explanation and nothing to trim; it fully assumes Claude's competence.

Actionability

The bash block is copy-paste ready and covers 14 concrete executable checks, but pass/fail semantics are inconsistent: check 1's header ('Services with try/catch') contradicts the table row ('Services without try/catch'), checks 9 and 12 emit bare 'wc -l' counts, and check 10 ends in '|| true' with no pass signal — minor gaps leaving Claude to infer how to fill the PASS/FAIL column.

Workflow Clarity

The sequence is clear (scope via $ARGUMENTS → run all checks → summary table → X/14 score) and the skill is read-only so the destructive/batch validation cap does not apply, but per-module scoping is undefined ('Scope: $ARGUMENTS' yet every command is hardcoded to src/modules/*) and Occurrences semantics for the count-only checks are left implicit.

Progressive Disclosure

A single cohesive, well-sectioned script ('## Automated Checks' plus output format) with no bundle files; everything is needed on every invocation so inline placement is appropriate, and nothing that belongs in a separate file is inlined.

Specificity

Names the domain ('checking if code follows ARCHITECTURE.md patterns') and a single action ('runs automated conformance checks'), but does not list what the checks actually cover (services, components, stores, imports, types) — matching '1-2 concrete actions, not comprehensive' rather than level 4's 'several specific actions'.

Completeness

The 'when' is explicit and concrete ('Use when checking if code follows ARCHITECTURE.md patterns') and the 'what' is present ('runs automated conformance checks'), but the 'what' is a single generic action rather than the comprehensive, concrete action list required for level 5.

Trigger Term Quality

'ARCHITECTURE.md' and 'conformance checks' are terms a user might naturally say, but coverage is narrow: common variations like 'architecture review', 'architecture compliance', or 'module boundaries' are absent, fitting 'some relevant keywords but missing common variations or synonyms'.

Distinctiveness Conflict Risk

'ARCHITECTURE.md patterns' carves a clear, mostly distinct niche, but 'checking if code follows patterns' loosely overlaps general code-review or design-pattern requests, leaving minor overlap risk with closely related skills rather than level 5's minimal risk.
