Conciseness

The body is largely lean — compact code blocks, tables, and no library tutorials — but has minor over-explanation that could be trimmed: the Overview states GDPR basics Claude already knows ('in force 2018-05-25', 'fines up to €20M or 4% of global annual turnover'), and the 'Key compliance gaps' and 'Anti-patterns' tables overlap substantially (multi-store erasure, hardcoded 30-day window, consent revocation appear in both). This matches 'Efficient; minor instances of over-explanation that could be trimmed' rather than 5, and is well above the 3 anchor's 'some unnecessary explanation'.

Actionability

The seven per-Article Python patterns are concrete, framework-realistic, and nearly copy-paste ready, with a specific fixture tool named ('Generate fixture data with `synthetic-pii-generator`'). Not 5 because of minor executability gaps: `test_consent_revocable` uses `user` without defining it, and `assert response.headers['X-Processing-Time'] < timedelta(days=30)` compares a header string to a timedelta, which would fail as written. Not 3 because the guidance is genuinely executable apart from these small spots, not pseudocode.

Workflow Clarity

'How to use' gives a clear 7-step sequence from PII inventory through CI wiring, with an explicit validation checkpoint ('Wire the tests into CI so a schema change that reintroduces PII or skips a system fails the build'), and the 'Worked example' section demonstrates an explicit fail → fix → re-run feedback loop. The gaps and anti-patterns tables function as checklists. This matches the top anchor: clear sequence, explicit validation, feedback loop, and checklists.

Progressive Disclosure

The body is a well-sectioned overview (when/how to use, patterns, worked example, limitations, references) and the CCPA/CPRA catalog is appropriately split into references/ccpa.md — verified to exist and to be one level deep (only external links inside, no nested .md references). It is well-signaled in three places (Overview, frontmatter description, References section), matching 'Clear overview with well-signaled one-level-deep references; content appropriately split'.

Specificity

The description enumerates concrete capabilities exhaustively: 'data-subject-rights workflows (Art. 15 access, Art. 16 rectification, Art. 17 erasure / "right to be forgotten", Art. 18 restriction, Art. 20 portability, Art. 21 objection); consent recording + revocation per Art. 7; data-residency assertions... breach-notification timing tests per Art. 33 (72 hours); data-minimization assertions in fixtures per Art. 5(1)(c)'. Each clause names a specific test pattern rather than vague capability language, matching the 'multiple specific concrete actions; comprehensive coverage' anchor. It is not score 4 territory because there is no gap in coverage — even the CCPA/CPRA analogue capabilities are itemized ('GPC opt-out, right-to-know, deletion, right-to-correct, and sensitive-PI limits').

Completeness

Both questions are answered explicitly: the 'what' is 'Reference catalog of GDPR-aligned test patterns' with the full per-Article enumeration, and the 'when' is the explicit trigger clause 'Use when authoring GDPR- or CCPA/CPRA-readiness tests for any product processing EU or California personal data'. This matches the top anchor with concrete trigger phrases; the 'Use when...' clause is present, so the completeness cap of 3 does not apply.

Trigger Term Quality

Natural phrases users would say when they need this skill are comprehensively covered with synonyms: 'GDPR', 'CCPA/CPRA', 'erasure / "right to be forgotten"', 'data portability', 'consent', 'breach notification', 'international transfers', 'readiness tests', 'personal data'. Not 4 because common variations and synonyms are present (erasure + right to be forgotten, GPC opt-out + Global Privacy Control, EU + California framing).

Distinctiveness Conflict Risk

The skill occupies a clear niche (GDPR/CCPA compliance test authoring) with distinct triggers ('Art. 17 erasure', 'Art. 33 breach notification', 'GPC opt-out') unlikely to collide with general testing or privacy skills. Voice is third person ('lives in references/ccpa.md'), so no voice penalty applies.
