shopify-custom-data

MUST be used first when prompts mention Metafields or Metaobjects. Use Metafields and Metaobjects to model and store custom data for your app. Metafields extend built-in Shopify data types like products or customers, Metaobjects are custom data types that can be used to store bespoke data structures. Metafield and Metaobject definitions provide a schema and configuration for values to follow.

Quality

Content

72%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

Highly actionable content with comprehensive executable examples and a clear create-write-read sequence. Weaknesses are the absence of verification checkpoints after writes and a monolithic single-file structure that inlines sub-domains rather than splitting them into referenced files.

Suggestions

Add a verification step after writing (e.g., read the metafield/metaobject back to confirm the value persisted) to close the write -> read loop and add a validation checkpoint.

Move the checkout-extension and Shopify Functions guidance into separate reference files linked from the body, keeping SKILL.md a concise overview with one-level-deep references.

Trim emphatic filler ("REMEMBER!!!", "NEVER, EVER", "99.99% / 0.01% of apps") in favor of concise directive statements.

DimensionReasoningScore

Conciseness

Mostly lean code examples with little concept re-teaching, but emphatic filler ("REMEMBER!!!", "NEVER, EVER", "99.99% of apps") adds tokens that could be trimmed.

4 / 5

Actionability

Fully executable, copy-paste-ready TOML, GraphQL, and TSX examples cover the common create-definitions / write / read / checkout / Functions cases.

5 / 5

Workflow Clarity

A clear FIRST/NEXT/FINALLY sequence (definitions -> write -> read) is present, but there are no validation or verification checkpoints for the write operations.

3 / 5

Progressive Disclosure

Well-sectioned single file with only an external docs link, but all content (including the checkout-extension and Shopify Functions subsections) is inlined with no one-level-deep references.

Description

82%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-targeted description that clearly states both purpose and trigger conditions using concrete Shopify terminology. The main weakness is that the stated capabilities lean slightly abstract rather than enumerating concrete operations.

DimensionReasoningScore

Specificity

Names the domain and several actions ("model and store custom data", "extend built-in Shopify data types", "store bespoke data structures") but the actions stay abstract rather than concrete operations.

3 / 5

Completeness

Explicitly answers what ("model and store custom data... provide a schema and configuration") and when ("MUST be used first when prompts mention Metafields or Metaobjects") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Strong natural keywords ("Metafields", "Metaobjects", "custom data") with an explicit trigger clause, though it lacks synonyms or file-extension variants.

4 / 5

Distinctiveness Conflict Risk

Highly specific to Shopify Metafields/Metaobjects with distinct triggers and minimal overlap with other skills.
