Conciseness

The ~35-line body contains only project-specific knowledge Claude cannot infer (the ARCHITECTURE.md pattern rules, the exact commands) with zero padding or explanation of known concepts, matching anchor 5's 'lean and efficient; every token earns its place'. There is nothing to trim that would not remove information.

Actionability

Concrete, executable commands are given for every automated step (git diff --name-only HEAD~1, npx tsc --noEmit, ng lint, ng test --watch=false) plus explicit classification and verdict taxonomies, matching anchor 4's 'mostly executable guidance with minor gaps'. It falls short of anchor 5 because $SCOPE in step 2b is never defined and step 5 gives no report format or example, leaving two steps not fully copy-paste ready.

Workflow Clarity

Steps 1-5 form a clear sequence with automated checks (tsc, lint, tests, architecture validation) acting as checkpoints and a classification scheme before the verdict, fitting anchor 4's 'clear sequence with most checkpoints present; minor validation gaps'. The destructive/batch cap does not apply (read-only review), but it stays below anchor 5 because there is no error-recovery guidance (e.g. what to do when tests fail) and the 2b/3 numbering disrupts the sequence.

Progressive Disclosure

The skill is under 50 lines, requires no external reference files (verified: no references/, scripts/, or assets/ directories exist in the bundle), and is organized into clear sections, so per the rubric's simple-skill guideline it earns anchor 5. The external pointer to docs/ARCHITECTURE.md is appropriate and one level deep.

Specificity

"validates architecture, types, security, and test coverage" lists several concrete validation targets, matching anchor 4's 'several specific actions; minor gaps in coverage'. Not a 5 because key capabilities from the body (producing a report, issuing an Approved/With caveats/Requires changes verdict) are not mentioned, and not a 3 because more than 1-2 concrete actions are named.

Completeness

Both questions are answered: what ("validates architecture, types, security, and test coverage") and when ("Use when code changes need review before merge"). It sits at anchor 4 rather than 5 because the 'when' clause covers a single scenario and lacks the multiple concrete trigger phrases of the anchor 5 example.

Trigger Term Quality

"Use when code changes need review before merge" supplies natural phrases users would say (review, code changes, merge), fitting anchor 4's 'good keyword coverage; a few natural terms missing'. Missing common variations like 'PR', 'pull request', 'diff', or 'code review' itself, which keeps it below anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

Pre-merge code review is a recognizable niche with distinct triggers, but the description overlaps with generic code-review and linting skills, matching anchor 4's 'mostly distinct; minor overlap risk with closely related skills' rather than anchor 5's minimal conflict risk.
