The description names the domain ('Databricks SQL advanced features and SQL warehouse capabilities') and lists many specific features/keywords, but it reads more like a keyword list than a description of concrete actions. It doesn't say what it *does* with these features (e.g., 'creates materialized views', 'writes stored procedures').

The description answers both 'what' (Databricks SQL advanced features and SQL warehouse capabilities) and 'when' with an extensive explicit trigger list using 'MUST be invoked when' and 'SHOULD also invoke when' clauses. The 'when' guidance is exceptionally detailed.

Excellent coverage of natural trigger terms users would actually say, including abbreviations ('DBSQL'), full names ('Databricks SQL'), specific syntax ('|>', 'ST_', 'WITH RECURSIVE'), function names ('ai_query', 'ai_classify'), and conceptual terms ('geospatial', 'Lakehouse Federation'). Very comprehensive keyword coverage.

Highly distinctive due to the Databricks-specific terminology and the extensive list of unique trigger terms like 'DBSQL', 'SQL warehouse', 'ai_query', 'Lakehouse Federation', and 'pipe syntax'. Unlikely to conflict with generic SQL skills or other platform-specific skills.

The content is highly efficient — no unnecessary explanations of what SQL is, what Databricks does, or how basic concepts work. Every section jumps straight to syntax and executable examples. The quick reference table is an excellent token-efficient way to provide an overview.

Every feature is demonstrated with complete, executable SQL examples including realistic table references (catalog.schema.table), proper syntax, and invocation patterns. Examples cover error handling, parameterized procedures, and real-world use cases like upserts and hierarchy traversal.

While individual examples are clear and well-sequenced, there are no explicit validation checkpoints or feedback loops. For operations like stored procedures with error handling or materialized view creation, there's no 'verify the result' step. The guidelines mention using MCP tools to test SQL but this is a brief bullet point rather than an integrated workflow step.

Excellent structure: a quick reference table maps features to reference files, common patterns provide just enough inline examples to be useful, and a clear 'Reference Files' table tells exactly when to load each detailed file. References are one level deep and well-signaled with descriptive 'When to Read' guidance.
