Conciseness

The body is lean throughout — 'The criteria are the contract — automated tests cover correctness, QA covers feature-level behavior' and 'Avoid criteria that combine multiple `when`s or `then`s. Split them.' add useful framing without explaining concepts Claude already knows, matching the lean-and-efficient anchor; it is not 4 because there is no padded or over-explained section to trim.

Actionability

It provides a copy-paste Given/When/Then template, a concrete worked example, an 8-item coverage checklist, named evidence types, and a Pass/Fail/Blocked handoff structure — fully actionable guidance; per the instruction-only scoring note, absence of code is not penalized, and it is not 4 because no key execution detail is missing.

Workflow Clarity

The implied sequence (write criteria covering 8 areas → run a verification pass with evidence → quarantine failures → handoff) has explicit validation checkpoints ('"Looks good to me" without evidence is not a pass', 'A failing criterion blocks acceptance') and a feedback loop ('If you add a new criterion mid-pass, restart the pass'), matching the clear-sequence-with-validation anchor; it is not 4 because checkpoints and error-recovery loops are explicit rather than implicit.

Progressive Disclosure

A single self-contained SKILL.md with no bundle files and clear section headers (When to use, When not to use, format, coverage, evidence, quarantine, handoff, anti-patterns) is appropriately structured and easy to navigate with nothing that should be split out; it is not 4 because organization is clean with no buried or nested references.

Specificity

Quotes 'Produce QA acceptance criteria and a manual validation plan' plus the enumerated 'golden path, edge cases, error states, performance limits, and explicit pass/fail evidence' list multiple concrete coverage areas, matching the comprehensive-coverage anchor; it is not the 4 anchor because no meaningful coverage category is missing.

Completeness

The 'what' is explicit ('Produce QA acceptance criteria and a manual validation plan for a feature change') but no 'Use when...' or equivalent trigger guidance exists, so per the missing-trigger-rule completeness is capped at 3; it is not 2 because the 'what' is clear rather than vague, and not 4 because 'when' is entirely absent rather than merely weak.

Trigger Term Quality

Natural terms like 'QA acceptance criteria', 'validation plan', 'edge cases', and 'pass/fail evidence' map to what a reviewer would actually say, fitting the good-coverage anchor; it is not 5 because synonyms such as 'test plan', 'verification', or 'QA pass' are absent and no 'Use when' trigger phrasing is present.

Distinctiveness Conflict Risk

The 'acceptance criteria and manual validation plan' framing carves a distinct QA niche with low conflict risk, matching the mostly-distinct anchor; it is not 5 because there is residual overlap risk with adjacent testing/QA skills given no explicit trigger scoping.
