Conciseness

The 26-line body is lean and assumes Claude's competence: "Determine the set of changed files in the current session (e.g. `git status`, `git diff`)" and "Do not modify files. Do not run commits, pushes, or other write operations" give instructions without explaining concepts Claude already knows. Every line earns its place, matching the anchor-5 example of lean, efficient content.

Actionability

Concrete, executable guidance throughout: specific commands (`git status`, `git diff`), a named tool ("use the `addComment` tool to attach a comment to the exact file URI and line range"), explicit comment-content rules, and a five-item review checklist. It falls short of anchor 5 only because there is no example of a well-formed comment or an exact `addComment` invocation to copy from — minor gaps consistent with anchor 4. Per the rubric's code_vs_instruction note, the absence of code in this instruction-only skill is not penalized.

Workflow Clarity

The six numbered steps form a clear sequence (identify changes → review against criteria → attach inline comments → stop), with an explicit end checkpoint ("When you have finished reviewing every changed file, stop") and a checklist of review dimensions. It sits at anchor 4: most checkpoints are present, but there is no explicit verification pass (e.g., re-checking `git status` to confirm no changed file was skipped). The workflow is read-only, so the destructive/batch validation cap does not apply.

Progressive Disclosure

The skill is under 50 lines with no need for external references (none exist in the bundle), and the content is well organized into a role statement plus a "Workflow" section with sub-bullets. Per the rubric's guideline for short skills with no external references, well-organized sections alone merit anchor 5.

Specificity

"Perform a code review of the current session's changes" names the domain and one concrete action but does not enumerate what the review covers (e.g., finding bugs, leaving inline comments). This matches the anchor for 1-2 concrete actions without comprehensive coverage; it is not generic enough for 2 and lacks the several specific actions needed for 4.

Completeness

It answers both "what" ("Perform a code review of the current session's changes") and "when" ("Use when the user requests a code review via the Run Code Review button") in third person. The "when" is explicit but narrow (a single UI trigger rather than natural trigger phrases), and the "what" is thin, matching anchor 4 rather than the comprehensive both-parts anchor 5.

Trigger Term Quality

"code review" and "changes" are relevant natural keywords, but common variations users would say ("review my changes", "diff", "look over this code") are absent, and the trigger leans heavily on the UI button phrase "Run Code Review button in the Changes toolbar". Some relevant keywords with missing synonyms fits anchor 3, short of anchor 4's good coverage.

Distinctiveness Conflict Risk

"code review" plus the specific UI-button trigger gives a clear niche distinct from unrelated skills, but the term overlaps with closely related review skills (security review, PR review), fitting anchor 4 ("mostly distinct; minor overlap risk") rather than anchor 5's minimal conflict risk.
