Conciseness

The body is dense and rule-per-sentence with no explanations of concepts Claude already knows, but authorization and evidence rules recur across sections ("explicit repair authorization" in the intro, the Authorization bullet in Outcome Contract, "explicit write authorization" in Autofix Routing) and could be merged. Efficient with minor tightening opportunities, matching the 4 anchor rather than 5's every-token-earns-its-place.

Actionability

Guidance is copy-paste executable throughout: exact commands ("git status --short --branch -uall", "gh run view <id> --json status,conclusion", "git fetch origin pull/<n>/head:refs/tmp/pr-<n>", "bash <skill-base-dir>/scripts/run-tests.sh", "git worktree add --detach <known-good-commit>"), numeric depth thresholds ("Under 100 lines, 1-5 files"), and concrete decision tables (Mode Picker, Autofix Routing). Per the instruction-skill scoring note, the absence of program code is not penalized since the direction is fully actionable.

Workflow Clarity

A clear ordered pipeline (Worktree Safety Preflight → Mode Picker → Project Context Extraction → Get the Diff → Scope → findings gates → Verification → Sign-off) with explicit validation checkpoints ("re-run the check that exposed the finding", regression test "must... run red on that code", isolated-worktree verification) and feedback loops for error recovery (rounds converge at three, setup-vs-product failure classification, hollow-green detection). The sign-off block is a literal checklist, matching the 5 anchor.

Progressive Disclosure

Good structure with conditional loading via the Mode Picker table, and all 11 referenced paths (10 references/*.md files plus scripts/run-tests.sh) exist on disk and are clearly signaled. Not 5 because a few references chain a second level (mode-ship.md points on to references/project-context.md, public-reply.md, and release-surfaces.md) and the ~230-line body inlines substantial rule content that an overview-plus-references split would move out — minor organization gaps per the 4 anchor.

Specificity

"Reviews diffs, PRs, release readiness, and publishing follow-through" plus "triage issues or PRs, or ship" names multiple concrete actions that comprehensively cover the skill's domain, matching the anchor for multiple specific concrete actions. Not 4 because coverage of the review/triage/release/ship surface is complete rather than having minor gaps.

Completeness

Both parts are explicit: the what ("Reviews diffs, PRs, release readiness, and publishing follow-through") and the when with concrete trigger phrases ("Use when asked to review, triage issues or PRs, or ship"), plus a negative scope clause ("Not for debugging root causes or prose"). This clearly matches the anchor for explicitly answering both what and when with concrete triggers.

Trigger Term Quality

"Use when asked to review, triage issues or PRs, or ship" gives good natural keyword coverage, but common variations a user would actually say — "code review", "before merge", "audit", "release" — are absent from the description itself. Not 5 because the trigger set is not comprehensive over synonyms; not 3 because the terms present are the natural phrasings, not jargon.

Distinctiveness Conflict Risk

The domain carve-out ("diffs, PRs, release readiness, and publishing follow-through") and the exclusion ("Not for debugging root causes or prose") remove the largest overlap areas, leaving mostly distinct triggers. Not 5 because the bare trigger "review" is generic and still invites overlap with closely related review skills (e.g., prose or built-in PR-review commands).
