Conciseness

Mostly lean — dense tables, executable commands, and smart deferral of full flag documentation to `-h` discovery. Deducted for dated time-sensitive info in prominent blockquotes ("March 2026", "June 2026") outside a deprecated section and the schema-permission recovery flow being duplicated between the What's Next section and the Troubleshooting table.

Actionability

Fully specified CLI commands with JSON payloads, a JSON-path table for extracting connection values, SQL grants, and a copy-paste scriptable version. Not 5 because `user=<USERNAME>` is never sourced — no step or JSON path indicates where the username comes from, breaking the flagship psql flow's executability.

Workflow Clarity

Create → verify → extract-connection-values is checkpointed, and the deploy-first app workflow has an explicit sequence plus a full error-recovery loop (permission denied → export options A/B) with destructive delete gated on explicit user permission. Not 5 because destructive `reset-branch` ("Local changes are lost") lacks a confirmation checkpoint unlike delete, and update/reset workflows have no verify step.

Progressive Disclosure

Good structure: an overview body with a clearly labeled reference-docs list of six one-level-deep files, all verified to exist, each with a topic description. Not 5 because `references/medallion-from-cdc.md` exists in the bundle but is never linked from SKILL.md (hurting discoverability), and the What's Next section mixes workflows with reference pointers.

Specificity

Lists five concrete capability areas ("projects, scaling, connectivity, Lakebase synced tables, and Data API") with comprehensive coverage, but they are noun topics rather than the concrete action phrases of the top anchor ("Extract text and tables... fill forms, merge documents").

Completeness

Clearly answers both what ("projects, scaling, connectivity, Lakebase synced tables, and Data API") and when with an explicit trigger clause ("Use when asked about Lakebase databases, OLTP storage, or connecting apps to Postgres on Databricks"), matching the top anchor exactly.

Trigger Term Quality

Good natural keyword coverage ("Lakebase databases", "OLTP storage", "connecting apps to Postgres on Databricks"), but a few natural terms users would say are missing, e.g. "Reverse ETL" for synced tables and generic Postgres task phrasing. Not the 5 anchor since synonyms like file extensions or product aliases are absent.

Distinctiveness Conflict Risk

Clear niche (Databricks Lakebase Postgres) with distinct triggers and minimal conflict risk, but "OLTP storage" is not Databricks-scoped and could overlap generic database questions or the databricks-core parent skill. Not 3 because the product-specific terms dominate.
