Conciseness

The body never explains concepts Claude already knows and every rule is project-specific, but at ~340 lines (21 KB) it is heavily padded with edge-case policy (autocrlf precedence, catalogue byte-copy semantics, per-model retry matrices) delivered in long dense paragraphs that could be substantially tightened. Accurate verbosity still costs tokens, matching 'mostly efficient but could be tightened' rather than anchor 4's minor trims.

Actionability

Commands are copy-paste ready and complete: the run snippet with $AUTOREVIEW, the PR merge-base recipe using gh and git merge-base, the --source-context and --codex-config examples with exact flags, model names, and environment variables. The mode-selection table maps each target to concrete arguments.

Workflow Clarity

The sequence is coherent (read the diagnostics reference first, run the helper, choose the Git target from the table, select engine and severity threshold, follow diagnostics for results) and checkpoints exist (--dry-run, validated JSON, exit code 2 semantics, fail-closed behavior). It falls short of anchor 5 because the ordering is implied by prose rather than an explicit sequence, and several validation details are deferred to the referenced file.

Progressive Disclosure

Both references (diagnostics-and-results.md, repository-entrypoint.md) are real, clearly signaled, and one level deep. However, large amounts of rarely-needed operational detail — engine retry/fallback matrices, macOS temp isolation, provider catalogue and authentication-path rules, image size limits — are inlined in SKILL.md where a reference file belongs, matching 'content that should be separate is inline.'

Specificity

The description names the domain ('Structured code review') and one concrete capability plus the engine preference ('preferring OpenAI/Codex before Claude'), but does not enumerate the skill's actual actions (target selection, severity filtering, structured output). This matches 'names domain and 1-2 concrete actions, but not comprehensive' rather than anchor 4's list of several specific actions.

Completeness

Both parts are present: what ('Structured code review... preferring OpenAI/Codex before Claude') and when ('when explicitly requested'). The when-clause is explicit but generic and could name concrete trigger situations, matching anchor 4 ('when' could be more explicit or specific) rather than anchor 5's concrete trigger phrases.

Trigger Term Quality

'code review' is a natural term users would say, but common variations and synonyms are absent ('review my code', 'review this PR/diff', 'second opinion'), and 'when explicitly requested' is a meta-condition rather than a natural trigger phrase. Some relevant keywords exist, but coverage is incomplete.

Distinctiveness Conflict Risk

The OpenAI/Codex-before-Claude routing gives the skill a clear niche that ordinary code-review skills do not share, leaving only minor overlap risk with closely related review skills. It is not anchor 5 because 'structured code review' alone still overlaps the broad review-skill category.
