Conciseness

The same instructions are stated twice: the opening 'Required Tool Calls' list and the later 'MANDATORY' sections repeat the search and validate commands, including the identical parenthetical about YOUR_ARTIFACT_ID and REVISION_NUMBER (lines 17 and 67), and two near-duplicate privacy notices (lines 83 and 87). Lines 34-42 also pad with generic advice Claude already knows ('Consider privacy and data protection requirements', 'validate required fields'). This matches anchor 2 (noticeably verbose, several unnecessary or padded sections) — worse than anchor 3's 'some unnecessary explanation', better than anchor 1 since nothing is a from-scratch concept tutorial.

Actionability

Commands are concrete and executable: exact invocations of `scripts/search_docs.mjs "<query>"` and `scripts/validate.mjs` with every flag spelled out, placeholders explained, a worked search example ('customer orders query'), and an explicit 3-retry error loop. The gap keeping it from anchor 5: no example GraphQL query or mutation anywhere, and placeholders like YOUR_MODEL_NAME must be filled in by the reader. Anchor 4 (mostly executable, concrete commands with minor gaps) is the best fit.

Workflow Clarity

The sequence is explicit and well-ordered (search → write code → validate → on failure search the error type, fix, re-validate, max 3 retries → return only after passing), with a mandatory validation checkpoint and a feedback loop, matching the anchor-5 pattern. It drops to anchor 4 because the workflow is presented twice in competing forms (the top 'Required Tool Calls' list vs. the MANDATORY sections) with slightly different framing, and the retry budget is stated inconsistently ('max 3 retries' as retries vs. 'Retry up to 3 times total'), which a careful reader must reconcile.

Progressive Disclosure

The body is organized into clear sections and the two referenced bundle files (`scripts/search_docs.mjs`, `scripts/validate.mjs`) both exist and are one level deep — verified against the actual bundle. This fits anchor 4 (good structure, references mostly clear, minor gaps). It is short of anchor 5 because `assets/customer_2026-04.json.gz` sits in the bundle unmentioned and undocumented, so navigation of the bundle is incomplete; it is well above anchor 3 since nothing that belongs in a separate file is inlined.

Specificity

It names the domain ("Customer Account API") and concrete data objects ("orders, payment methods, and addresses"), but the only action named is the generic "allows customers to access their own data" — it never states what the skill itself does (write GraphQL queries/mutations). This matches anchor 3 (names domain and 1-2 concrete actions, not comprehensive); it is above anchor 2 because the data types are specific, and below anchor 4 because no skill-level actions are listed.

Completeness

The "what" is stated clearly (access to orders, payment methods, addresses), but there is no "Use when..." clause or any equivalent trigger guidance — the description never says when Claude should invoke this skill. Per the judging guideline, a missing 'Use when' clause caps completeness at 3, which this matches exactly (clear 'what', 'when' missing).

Trigger Term Quality

Relevant keywords exist ("Customer Account API", "customers", "orders", "payment methods", "addresses"), but common natural variations are missing: no "Shopify", "GraphQL", "query", "account management", or "profile". This fits anchor 3 (some relevant keywords but missing common variations or synonyms); it lacks the broader coverage of anchor 4 and is well above anchor 2's single generic keyword.

Distinctiveness Conflict Risk

"Customer Account API" is a specific, well-scoped API surface, so the niche is mostly distinct, but it omits "Shopify" and "GraphQL", creating minor overlap risk with other Shopify/API skills (e.g., Admin API skills). This sits between anchor 3 (could still overlap with similar skills) and anchor 5 (clear niche with minimal conflict), matching anchor 4 (mostly distinct, minor overlap risk with closely related skills).
