Conciseness

The body is mostly efficient procedural instruction, but it carries several clearly unnecessary explanation blocks: the Section 2 blockquote essay ("This is a recurring shape: the sophisticated inner rule present, the outer boundary unguarded... what does this emit when the set is empty?") and Section 6's "Why this needed saying" rationale passages are skill-design commentary, not execution guidance. This matches anchor 3 (mostly efficient, some unnecessary explanation that could be tightened) — above anchor 2 because the padding is confined to a few blockquotes rather than pervasive, below anchor 4 because those passages run to tens of lines.

Actionability

The guidance is copy-paste ready throughout: exact Grep invocations with pattern, glob, output_mode and -A flags (Section 2); concrete per-engine test roots (`tests/unit/[system]/`, `Assets/Tests/EditMode/`, `Source/<Module>/Private/Tests/`); numeric thresholds ("3+ assertions per test function → normal"); per-engine naming patterns; and a complete fill-in report template. This matches anchor 5 (fully executable, specific examples covering the common cases) — nothing is pseudocode or hand-waved.

Workflow Clarity

The seven sections form a clear, sequenced workflow with explicit checkpoints and error-recovery routing: the zero-stories guard stops execution and routes to the correct next skill; the stated-evidence-path-first rule with a documented fallback search; full-read fallback when a Test Evidence section is missing or ambiguous; and the ask-before-write confirmation for the optional report. This matches anchor 5 (clear sequence, explicit validation steps, feedback loops); the read-only nature of the skill means no destructive-operation cap applies.

Progressive Disclosure

No bundle files exist, and the body's references (`.claude/docs/coding-standards.md`, `.claude/rules/test-standards.md`, `.claude/docs/directory-structure.md`, `.claude/docs/automation-modes.md`) are one level deep and clearly signaled at the point of use, matching anchor 4 (good structure, references mostly clear, minor organization gaps). It is not anchor 5 because at ~350 lines the SKILL.md is a monolith — the detailed per-story-type gate logic and the full report template are candidates for a bundled reference file — though the references that do exist are external project docs rather than nested skill files, so it is comfortably above anchor 3.

Specificity

The description names its domain ("test files and evidence") and 1-2 concrete actions ("Quality review", "evaluates assertion coverage"), but does not enumerate the fuller set of capabilities the body actually performs (sign-off checks, screenshot/artefact completeness, criterion linkage). This matches anchor 3 (domain + 1-2 concrete actions, not comprehensive); it is above anchor 2 because the actions are specific rather than generic, and below anchor 4 because the verdict vocabulary line describes output labels rather than additional concrete actions.

Completeness

The 'what' is clear ("Quality review of test files and evidence — goes beyond existence, evaluates assertion coverage"), but there is no 'Use when...' clause or any equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. Anchor 3 fits: clear 'what', 'when' entirely missing — not anchor 4, which requires an explicit (if imperfect) 'when'.

Trigger Term Quality

Relevant keywords are present ("test files", "evidence", "assertion coverage", "test"), but common natural variations users would say — "test quality", "QA", "sign-off", "coverage" in the generic sense — are absent, matching anchor 3 (some relevant keywords, missing variations/synonyms). It is above anchor 2 because the terms present are domain-natural rather than generic, and below anchor 4 because the natural-phrase coverage is thin for a QA-adjacent skill.

Distinctiveness Conflict Risk

The pairing of "evidence" with "assertion coverage" and the ADEQUATE/INCOMPLETE/MISSING/NOT ASSESSED verdict vocabulary carve a clear niche that distinguishes it from generic code-review or test-running skills, matching anchor 4 (mostly distinct, minor overlap risk with closely related skills such as a smoke-check or story-closure skill). It is not anchor 5 because the first half ("Quality review of test files") alone would overlap with ordinary test/CI review requests.
