Conciseness

The body is command-first and terse ('If build fails, STOP and fix before continuing'), with only minor trimmable padding: the opening line repeats the frontmatter description, the 'Integration with Hooks' section explains a comparison Claude could infer, and the 'Continuous Mode' markdown block ('Set a mental checkpoint') is fluffy. This matches 'Efficient; minor instances of over-explanation' rather than score 5's every-token-earns-its-place.

Actionability

Every phase gives concrete, copy-paste-ready commands (`npm run build 2>&1 | tail -20`, `npx tsc --noEmit 2>&1 | head -30`, `pyright .`, `ruff check .`, specific grep patterns, `git diff --stat`), and the output template is fully specified. Minor gaps keep it below 5: alternatives are offered without selection guidance ('npm run build # OR pnpm build'), thresholds for lint/security failures are not defined, and the test-report fields are placeholders ('Total tests: X').

Workflow Clarity

Phases 1-6 are clearly sequenced with explicit checkpoints and some feedback loops ('If build fails, STOP and fix before continuing'; 'Fix critical ones before continuing'), plus a final report checklist — matching 'Clear sequence with most checkpoints present'. Not 5 because lint, test, and security phases say only 'Report' with no fix-and-retry loop or pass/fail criteria; not 3 since validation is explicit in the early phases and the skill is not destructive/batch, so no cap applies.

Progressive Disclosure

The skill is a single self-contained file (~140 lines) with clean, well-labeled sections (When to Use, six phases, Target Acceptance, Output Format) and no buried or nested references — matching 'Good structure; most content is appropriately placed'. Not 5 under the simple-skill note since it exceeds the under-50-line threshold, and the 'Continuous Mode' section is slightly underorganized.

Specificity

The description names the domain ('verification system for Claude Code sessions') but the only action offered is the generic 'verifying', with no concrete verbs for what is actually verified (build, types, lint, tests, security, diff). It matches the anchor 'Names the domain but actions are minimal or generic' — not score 3, which requires 1-2 concrete actions, and not score 1, since the domain is stated with a specific triggering condition.

Completeness

The 'when' is explicitly present ('Use when verifying a Claude Code session's work before claiming it is complete') but the 'what' is buzzword-vague: 'A comprehensive verification system' states no concrete capability. It sits between anchor 3 (clear what, weak when) and anchor 4 (both present, when improvable) — below 4 because the 'what' clause is pure abstraction, above 2 because an explicit 'Use when' trigger exists.

Trigger Term Quality

Relevant keywords exist ('verifying', 'verification', 'before claiming it is complete') but common natural variations users would say are missing: 'run the tests', 'check my work', 'quality gates', 'before opening a PR', 'pre-commit check'. This matches 'Some relevant keywords but missing common variations or synonyms' rather than score 4's 'Good keyword coverage'.

Distinctiveness Conflict Risk

'Verification system for Claude Code sessions' is somewhat specific but 'verification' is broad and would overlap with code review, testing, and CI-related skills, matching 'Somewhat specific but could still overlap with similar skills'. Not 4, since no distinctive trigger (e.g., 'before claiming work is done' alone) cleanly separates it from a general review/test skill.
