Conciseness

The body is commands, tables, and templates with no concept tutorials — it assumes Claude's competence ("The code is wrong until proven right"). The Lens Priority section re-enumerates many constitution principle IDs (COR-02/06/07/08/10/11, SEC-*, INC-*, CPX-*) that the already-mandated full read of review-constitution.md covers, which is trimmable duplication; efficient overall but not perfectly lean.

Actionability

Fully executable guidance: copy-paste-ready commands ("git diff --cached", "git ls-files --others --exclude-standard"), an exact finding-format template with fields and severity values, a mandated output structure, and a pattern-to-required-checks table for MockServer triggers. Not 4: there are no missing key details for executing the workflow.

Workflow Clarity

Eight clearly sequenced steps with an explicit validation gate — Step 7's "Before returning your verdict, verify ALL of these" checklist with per-item pass/fail, and a Step 8 rule banning hedged verdicts ("Do NOT use 'PASS with reservations'"). Sequence, explicit validation, and a checklist match the 5 anchor; the skill is read-only so no destructive-operation cap applies.

Progressive Disclosure

Good structure: the heavy 8-lens framework is correctly externalized and clearly signaled ("Read .opencode/rules/review-constitution.md in full"), one level deep, and the remaining sections are scannable. Not 5: the skill ships no bundle files, and the two dense inline tables (Lens Priority, MockServer triggers) plus reliance on a non-bundled repo path leave minor organization gaps; not 3 because references are clearly signaled, not buried.

Specificity

Lists multiple specific concrete actions — "Examines diffs for correctness, security, completeness" plus named concerns "ByteBuf leaks, module boundaries, javax/jakarta compatibility, ring buffer sizing" — with comprehensive coverage and no filler. Third-person voice throughout, so no voice penalty applies.

Completeness

Explicitly answers both: what ("Deep adversarial code review... Examines diffs for correctness, security, completeness, and MockServer-specific concerns") and when ("Use when performing pre-commit reviews, quality-loop iterations, or on-demand code audits"). This mirrors the anchor-5 example structure exactly.

Trigger Term Quality

Natural phrases users would say are present ("code review", "pre-commit reviews", "code audits", "diffs"), but common variations like "PR review", "pull request", or "find bugs" are missing. Coverage is good but a few natural terms are absent, matching the 4 anchor rather than the comprehensive 5.

Distinctiveness Conflict Risk

The 8-lens constitution framing, MockServer-specific concerns, and named loading agents ("Loaded by review-cheap and review-final agents") establish a clear niche, but the broad "code review" trigger carries minor overlap risk with generic review skills. Mostly distinct, matching the 4 anchor.
