databricks-unity-catalog

Unity Catalog governance, access control, and observability. Use to grant or revoke access (GRANT/REVOKE), reason about the privilege model and ownership, set up row-level security and column masks, create external locations and storage credentials, define catalogs/schemas/tables/volumes, answer "who can read this table", and query system tables (audit, lineage, billing) or work with volume files in /Volumes/.

Content

80%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.

A strong, highly actionable reference-hub skill body: executable CLI/SQL/SDK examples, excellent progressive disclosure into seven real one-level-deep references, and honest version-surface caveats. The main gaps are the absence of post-change verification checkpoints for governance operations (capping workflow clarity) and some repeated CLI-version warnings.

Suggestions

Add explicit verification checkpoints after state-changing operations — e.g., follow the GRANT/REVOKE example with a confirming `SHOW GRANTS ON SCHEMA analytics.gold` step so changes are validated rather than assumed (workflow_clarity).

State the "CLI surface varies by version" caveat once (in the intro blockquote) and refer back to it from the positional-args table and Running SQL sections instead of repeating it nearly verbatim three times (conciseness).

Trim the Related Skills list to the entries with genuine overlap risk (metric-views, iceberg, ai-functions) and compress the remaining sibling pointers into a single line (conciseness).

DimensionReasoningScore

Conciseness

The body is code-dominated with no explanations of concepts Claude already knows, but the "CLI surface varies by version" caveat is repeated three times (intro blockquote, after the positional-args table, in Running SQL) and the 9-entry Related Skills list runs long. Mostly efficient with minor trims available — not 5 because of that redundancy, not 3 because virtually all prose carries operational content.

4 / 5

Actionability

Fully executable, copy-paste-ready guidance throughout: CLI commands with the version-stable `--json` form, volume `fs` operations with the required `dbfs:` scheme, GRANT/REVOKE/SHOW GRANTS SQL, ready system-table queries, and a Python SDK fallback — with placeholders explicitly resolved ("run `databricks warehouses list`"). Matches the fully-executable anchor covering common cases.

5 / 5

Workflow Clarity

Sequences exist (create objects → grant access → query system tables) with a pre-flight check ("confirm the CLI and the subcommand exist. Run `databricks --version`") and fallback-on-error guidance, but state-changing database operations lack verify-after-change checkpoints — e.g., no `SHOW GRANTS` confirmation step after a GRANT/REVOKE. Per the rubric, database-operation workflows missing validation are capped at 3; not lower because the pre-flight check and fallback paths are present.

3 / 5

Progressive Disclosure

A clean overview body with a navigable Reference Files table; all 7 referenced files exist and are one level deep (they link only to sibling references, verified). The privilege model, per-table schemas, and other bulk detail correctly live in the reference files, and quick-start examples stay in the body. Easy navigation, appropriate split.

Description

100%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.

An exemplary description: concrete actions spanning the full governance and observability domain, an explicit "Use to..." trigger clause with natural user phrasing, and a distinct niche within the Databricks skill family. Third-person voice is maintained and every clause carries trigger or capability information.

DimensionReasoningScore

Specificity

Lists 7+ concrete actions — "grant or revoke access (GRANT/REVOKE)", "set up row-level security and column masks", "create external locations and storage credentials", "define catalogs/schemas/tables/volumes", "query system tables (audit, lineage, billing)" — comprehensively covering both governance and observability. This matches the comprehensive-coverage anchor; it is not 4 because no capability area of the domain is missing.

5 / 5

Completeness

"Unity Catalog governance, access control, and observability" explicitly states what the skill does, and "Use to grant or revoke access ... or work with volume files in /Volumes/" is an explicit when-clause with concrete trigger phrases. Both what and when are clearly and explicitly answered; not 4 because the when-clause is already specific rather than merely present.

5 / 5

Trigger Term Quality

Includes natural phrases users would actually say — "who can read this table", "grant or revoke access", "row-level security", "column masks", "audit", "lineage", "billing" — plus synonyms (grant/revoke) and concrete path term "/Volumes/". Matches the anchor requiring synonyms and extension-like terms; nothing common is missing.

5 / 5

Distinctiveness Conflict Risk

Clear niche (Unity Catalog governance and observability) with distinct triggers — GRANT/REVOKE, row-level security, external locations, storage credentials, /Volumes/ — that sibling Databricks skills (metric views, Iceberg, pipelines) would not fire on. Minimal conflict risk.
