Lists multiple specific concrete actions: 'Builds and modifies dbt models', 'writes SQL transformations using ref() and source()', 'creates tests', and 'validates results with dbt show'. These are precise, actionable capabilities.

Clearly answers both what (builds models, writes SQL transformations, creates tests, validates results) AND when with explicit 'Use when...' clause covering multiple trigger scenarios (building models, debugging, exploring data, writing tests, evaluating changes).

Includes natural keywords users would say: 'dbt', 'models', 'SQL transformations', 'ref()', 'source()', 'tests', 'dbt show', 'debugging errors', 'data sources'. Good coverage of domain-specific terms users would naturally mention.

Clear niche focused specifically on dbt tooling with distinct triggers like 'ref()', 'source()', 'dbt show', and 'dbt models'. Unlikely to conflict with generic SQL or data skills due to dbt-specific terminology.

The content is lean and efficient, assuming Claude's competence with dbt concepts. No unnecessary explanations of what dbt is or how SQL works - it jumps straight to actionable guidelines and references.

Provides clear guidelines and references to detailed guides, but lacks concrete executable code examples in the main skill file. Commands like `dbt show` and `dbt clone` are mentioned but not demonstrated with full syntax examples.

Clear workflow guidance with explicit validation checkpoints - emphasizes using `dbt show` regularly to validate, includes a 'STOP if you're about to' checklist, and references detailed workflow guides for specific tasks. The Common Mistakes table provides clear error recovery guidance.

Excellent structure with a clear overview and well-organized reference table pointing to one-level-deep guides for specific tasks. Content is appropriately split between the main skill and detailed reference files with clear navigation.
