The body is mostly tight operational prose that assumes Claude's competence, but repeated time-sensitive version stamps ("v0.25.1", "v0.27.x") scattered through sections and a redundant conformance-test "Output Format" stub that duplicates the earlier "Output format" section add clutter, fitting score 2 (mostly efficient, could be tightened) rather than the lean score-3 anchor.

Concrete elements exist (copy-paste output templates, numeric gating thresholds like "5+ files or 100+ lines"), but the core execution mechanic — how to spawn the review model — is externalized to conventions/model-routing.md (absent from this bundle) and the review step itself is stated as a directive ("Send the work + Contract") rather than executable instruction, matching score 2 (some concrete guidance, missing key details).

The five Phases are clearly sequenced with an explicit validation checkpoint (Grade = Pass/fail with citations), an error-recovery/escalation path (refusal routing ending in user escalation), and a user-approval gate, matching the score-3 anchor of a clear sequence with explicit validation steps; it is above score 2 because checkpoints are explicit, not implicit or missing.

Content is organized into clearly headed sections with well-signaled, one-level-deep references to supporting materials (conventions/cross-modal.yaml, model-routing.md, test-before-bulk.md) and a concise body, matching the score-3 anchor of a clear overview with well-signaled one-level-deep references and easy navigation; it stays above score 2 because references are clearly signaled rather than vague.

The description lists multiple concrete actions: "Spawn a different AI model to review work before committing", "if one model refuses, switch silently to the next", and a "Codex code-review handoff for the diff-review case", matching the score-3 anchor of multiple specific concrete actions rather than the single-domain score-2 anchor.

The "what" is clearly stated, but the "when" is only described as a feature ("structured review-mode gating (when to invoke vs not)") with no explicit "Use when..." trigger clause, so per the guideline a missing explicit trigger clause caps completeness at 2 rather than 3.

It includes relevant terms ("review", "second model", "Codex") but leans technical ("quality gate", "refusal routing", "review-mode gating") and omits the natural phrasings users would say ("second opinion", "double check", "another perspective"), fitting score 2 (some relevant keywords, missing common variations) rather than the full-coverage score 3.

The cross-modal/second-model pre-commit gate with refusal routing and Codex handoff is a clear niche with distinct framing unlikely to trigger for unrelated skills, matching the score-3 anchor rather than the overlapping score-2 anchor.
