Conciseness

The body is a lean, imperative checklist ('Run `npx ai-devkit@latest lint`', 'grep exported names to trace callers', 'Check consistency against 1-2 similar modules') with zero explanation of concepts Claude already knows and no padding. Every line is an instruction, matching 'Lean and efficient; assumes Claude's competence; every token earns its place.'

Actionability

Concrete commands are given (`npx ai-devkit@latest lint --feature <name>`, `git status -sb`, `git diff --stat`) and most steps name exactly what to check. Minor gaps remain: the tracing-event step says to 'emit review phase, progress, blocker/finding... events per `task`' without showing the event format, and no example of a finding's expected shape is given, so it falls just short of fully copy-paste-ready guidance.

Workflow Clarity

The sequence is explicit (Phase Contract 1-6, review steps 1-17, then a Done checklist) with validation checkpoints and error-recovery routing: 'Apply the `verify` skill before claiming readiness', 'if blocking issues remain, return to `dev-implementation` or `dev-testing`', and the final 6-item readiness checklist. This matches the anchor 'Clear sequence with explicit validation steps; feedback loops for error recovery; checklists for complex processes.'

Progressive Disclosure

The body is ~37 lines with no bundle files (references/, scripts/, assets/ are absent), organized into clear sections (Phase Contract, Code Review, Done) that hold all needed content inline. Cross-references to sibling skills (`verify`, `task`) are one level deep and clearly signaled. Per the rubric's simple-skill guideline, this earns a 5.

Specificity

Phrases like 'Final code review phase guidance', 'design alignment checks', and 'integration risk review' name the domain and a couple of concrete review activities, but coverage of what the skill actually does is not comprehensive (no mention of findings/severity reporting, breaking-change checks, or rollback safety). This matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'; a 4 would require several specific actions with only minor gaps.

Completeness

It has an explicit 'Use when...' clause listing five triggers (the 'when'), and a 'what' in 'Final code review phase guidance for holistic pre-push review'. The 'what' is somewhat abstract ('guidance', 'holistic') rather than concrete actions, so it sits at 'both present; when/what could be more explicit' — below the 5 anchor where both are concrete.

Trigger Term Quality

'Use when the user wants code review, final lifecycle review, design alignment checks, integration risk review' gives good coverage of natural phrases a user would say, anchored by the strong 'code review' trigger. A few natural variations are missing (e.g., 'review my changes', 'pre-PR check'), and 'dev-lifecycle phase 9' is internal jargon, keeping it below the 5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

'Use when the user wants code review' is a very broad trigger that would overlap with generic code-review skills, though the 'AI DevKit', 'dev-lifecycle phase 9', and 'final lifecycle review' qualifiers carve out a narrower niche. This lands at 'somewhat specific but could still overlap with similar skills' rather than 4's 'mostly distinct'.
