Conciseness

The body is dense, project-specific rule content with no re-teaching of concepts Claude already knows, so every line carries contract information. It is not a 5 because the Anti-Patterns section substantially restates the Core Rules ('No port-only readiness' vs the doctor rule, 'No evidence deletion' vs retention, 'No concurrent shared driving' vs single-driver ownership), which is trimmable duplication.

Actionability

For an instruction-only skill the guidance is concrete and directive: an explicit fallback path ('task/handoff first … then project docs, then `docs/verification/<app>/`'), raw AC ID formats, a discrepancy→required-action table, and unambiguous ownership/cleanup rules. It is not a 5 because operational specifics (actual doctor commands, evidence capture mechanics) are not shown even as illustrative examples, leaving minor execution gaps.

Workflow Clarity

The Verification Lifecycle is a clearly sequenced five-step process (Discovery → Doctor → Drive → Cleanup → Maintain & Report) with explicit validation checkpoints — 'Refuse execution if unhealthy', 'Failed or surprising drive requires doctor check and authorized owned reset before retry', 'Re-drive every claimed correction live before reporting changed' — plus a blocked-reporting rule. This matches the anchor-5 pattern of explicit validation steps with error-recovery feedback loops.

Progressive Disclosure

The body keeps the contract-level rules inline and delegates detail to two real, one-level-deep reference files, each clearly signaled with a one-line scope description ('[Kit Contract](references/kit-contract.md) — Discovery, README contract, journey mapping, and resource ownership'). Both referenced paths exist in the bundle and navigation is easy; no content that belongs in references is inlined.

Specificity

The description enumerates multiple concrete capabilities — 'journey mapping, read-only doctor checks, evidence retention, and map maintenance across web, mobile, and service targets' — giving comprehensive coverage of what the skill does. It is not a 4 because there are no notable gaps: both the standardization scope and the concrete operation types are explicitly listed.

Completeness

It clearly answers 'what' ('Standardizes project-owned verification kits, journey mapping, read-only doctor checks, evidence retention, and map maintenance') and 'when' via an explicit 'Use when…' clause with concrete trigger phrases. This matches the anchor-5 example pattern exactly; a 4 would require a less explicit 'when', which is not the case.

Trigger Term Quality

Natural trigger phrases are present and specific — 'creating verification kits, driving user journeys, validating instance health, scoping proof freshness, or classifying verification discrepancies' — which users of this domain would plausibly say. It falls short of 5 because common synonyms and variations (e.g., 'acceptance testing', 'e2e journeys', 'smoke checks') are absent.

Distinctiveness Conflict Risk

The niche (project-owned verification kits, proof freshness, discrepancy classification) is distinct with dedicated terminology, minimizing conflicts. Minor overlap risk remains with generic health-check or testing skills due to phrases like 'validating instance health' and the broad 'web, mobile, and service targets' scope, keeping it below 5.
