Conciseness

The body is ~37 lean lines with zero concept explanations and telegraphic, high-density rules ("Services: no try/catch, no transformation, use $fetch"), fully assuming Claude's competence; every token earns its place, matching anchor 5 rather than anchor 4 which allows minor trims.

Actionability

Copy-paste-ready commands are given ("git diff --name-only HEAD~1 2>/dev/null || git diff --name-only --cached ...", "nuxi typecheck", "npx eslint . --max-warnings 0") along with a concrete classification taxonomy and verdict options, matching anchor 4; it stops short of anchor 5 because items like "Naming: correct conventions" are vague and pattern details defer entirely to the external docs/ARCHITECTURE.md.

Workflow Clarity

A clear 1-5 sequence exists with explicit validation checkpoints (typecheck, eslint, vitest, automated pattern validation), matching anchor 4; it is below anchor 5 because there is no error-recovery guidance when checks fail, the numbering is inconsistent (a "2b" step), and the scope variable is defined as $ARGUMENTS but invoked as $SCOPE.

Progressive Disclosure

The skill is under 50 lines, needs no external reference files (none exist in the bundle), and is organized into clean sections with the compact pattern checklist inlined as core content, so the simple-skill exception applies for anchor 5; the external pointers (docs/ARCHITECTURE.md, /review-check-architecture) are clearly signaled and one level deep.

Specificity

"validates architecture, types, security, and test coverage" lists several concrete validation areas, matching anchor 4 (several specific actions, minor gaps); it is below anchor 5 because it never states what the skill produces (e.g., a report or verdict) and above anchor 3 because it covers four distinct areas rather than 1-2.

Completeness

Both parts are explicitly present: what ("validates architecture, types, security, and test coverage") and when ("Use when code changes need review before merge"), matching anchor 4; it is below anchor 5 because the when-clause covers a single scenario rather than multiple concrete trigger phrases.

Trigger Term Quality

"code changes", "review", and "before merge" are natural phrases users would say, giving good keyword coverage (anchor 4); it falls short of anchor 5 because common variations like "PR", "pull request", or "diff" are absent.

Distinctiveness Conflict Risk

Pre-merge code review with named validation domains (architecture, types, security, test coverage) carves a mostly distinct niche with only minor overlap risk against generic code-review skills, matching anchor 4; it is not anchor 5 because the trigger phrasing is broad enough to collide with a general review skill.
