json-typed-attributes

Define typed attributes backed by JSON fields in Rails models. Use when models need flexible data storage with type casting, validations, and form integration. Supports integer, decimal, string, text, boolean, date, and array types.

Content

65%

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

The body is highly actionable with comprehensive executable examples, but it is verbose due to redundant Best Practices/Common Patterns sections, lacks an explicit setup verification checkpoint, and is a long monolithic file with no progressive disclosure into reference files.

Suggestions

Consolidate the Best Practices and Common Patterns sections so they do not restate code already shown in the per-type sections; keep them as terse principles without repeating snippets.

Add an explicit verification step to the Setup workflow (e.g., reload a record in the Rails console and assert the cast value persists) so the multi-step sequence has a checkpoint.

Split the per-type reference, form integration, and troubleshooting material into one-level-deep reference files (e.g., TYPES.md, FORMS.md) linked from a leaner SKILL.md overview to improve progressive disclosure.

Dimension	Reasoning	Score
Conciseness	Prose is lean and free of basic-concept filler, but the Best Practices and Common Patterns sections rehash earlier snippets (field name, arrays, constants, validations, strong params) and the Complete Example duplicates the per-type sections, so it could be tightened; not 3 due to this redundancy.	2 / 3
Actionability	Provides abundant executable Ruby and Slim code across types, forms, validations, strong parameters, scopes, and troubleshooting — copy-paste ready and specific rather than pseudocode.	3 / 3
Workflow Clarity	Setup is a clear 3-step sequence (migration, include concern, define attributes), but there is no explicit verification checkpoint to confirm casting/persistence, and troubleshooting is reactive rather than an in-workflow validation step; not 3 because checkpoints are missing/implicit.	2 / 3
Progressive Disclosure	The ~394-line file is monolithic with all content inline (type reference, forms, troubleshooting could be split into one-level-deep reference files); sections are well-organized so not 1, but it is long and inline with no external references so not 3.	2 / 3
	Total	9 / 12 Passed

Description

100%

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

The description is specific, complete, and distinctive: it states concrete capabilities, provides an explicit 'Use when' trigger, enumerates supported types, and occupies a clear Rails/JSON niche. It reads as third-person with no fluff.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions ('Define typed attributes backed by JSON fields', 'type casting, validations, and form integration') plus an enumerated type list (integer, decimal, string, text, boolean, date, array), matching the 'lists multiple specific concrete actions' anchor.	3 / 3
Completeness	Explicitly answers what ('Define typed attributes backed by JSON fields in Rails models') and when via a clear 'Use when models need flexible data storage...' trigger clause, matching the 'both what AND when with explicit triggers' anchor.	3 / 3
Trigger Term Quality	Uses natural terms users would say ('JSON fields', 'Rails models', 'validations', 'form integration') in third person, with good coverage; not score 2 since common variations are present rather than missing.	3 / 3
Distinctiveness Conflict Risk	Targets a clear niche (JSON-backed typed attributes in Rails models) with distinct triggers unlikely to fire for unrelated skills; not score 2 because the scope is tightly bounded rather than broadly overlapping.	3 / 3
	Total	12 / 12 Passed
