Conciseness

Most of the body is a dense, useful reference (Shopify-specific tags, gotchas, filter lists), but it is noticeably redundant: the two trailing "MANDATORY" sections restate the workflow commands and 3-retry loop already given in "Required Tool Calls", and it explains basic Liquid (assign/capture, common string/math filters, delimiters) that Claude already knows. This fits anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened') better than anchor 2, since there is no concept-explaining padding of the bad-example kind.

Actionability

Commands are copy-paste ready with exact flags ("scripts/search_docs.mjs \"<query>\"", validate.mjs with --model/--artifact-id/--revision), and code examples like the block example with {% doc %}/{% stylesheet %}/{% schema %} are complete and executable. It falls short of 5 due to minor gaps: placeholders require substitution (acceptable but explicit), and several referenced targets (schemas/section.json, schemas/theme_block.json, search_docs_chunks) do not exist in the bundle.

Workflow Clarity

The workflow is an explicit numbered sequence — search before writing, write, validate before returning, "If validation fails: search for the error type, fix, re-validate (max 3 retries)", and "Return code only after validation passes" — with two validate modes (full-app vs. stateless) and an error-message-driven recovery loop. This matches the top anchor exactly: clear sequence with explicit validation, feedback loops, and retry limits.

Progressive Disclosure

Headers and sections are well organized and the runtime-doc-lookup via scripts is a legitimate one-level disclosure mechanism, but the ~200-line inline Liquid reference (filters, tags, global objects) is content that belongs in a separate reference file, and references to schemas/section.json, schemas/theme_block.json, schemas/theme_settings.json, schemas/translations.json, and search_docs_chunks point at files/tools that do not exist in the bundle. This sits between anchor 2 (inline content that belongs in separate files) and anchor 3 (structured but should be split), landing at 3 because the organization itself is good.

Specificity

Phrases like "Liquid is an open-source templating language created by Shopify" and "used to load dynamic content on storefronts" name the domain clearly but state zero concrete skill actions — the description defines the language rather than what the skill does (e.g., generating sections, blocks, or snippets). This matches the anchor 'Names the domain but actions are minimal or generic'; it is above score 1 because it is not entirely vague, but below score 3 because no actionable capability is listed at all.

Completeness

There is no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3; the 'what' is also only vague — "It is the backbone of Shopify themes" describes Liquid, not the skill's function. This fits anchor 2 ('Has a vague what and no when') better than anchor 3, whose example at least lists the skill's concrete actions.

Trigger Term Quality

The keyword list ("liquid, theme, shopify-theme, liquid-component, liquid-block, liquid-section, liquid-snippet, liquid-schemas") gives good coverage of what a user asking for Shopify theme work would say, including compound variants. It falls short of score 5 because natural terms like the ".liquid" file extension, "Shopify theme development", "storefront", or "template" are missing.

Distinctiveness Conflict Risk

"created by Shopify... backbone of Shopify themes" plus keywords like "shopify-theme" and "liquid-section" establish a clear niche (Shopify Liquid theme development) with distinct triggers and minimal overlap risk with generic web-dev or templating skills.
