Conciseness

The body is mostly efficient pointers and commands, but the App naming rule is stated twice in near-identical detail (General Guideline 7 and the Required App Completion Contract bullets), Guideline 7 is a single 60+ word run-on sentence, and version numbers ("Databricks CLI 0.270.0 or later", appearing twice) are scattered rather than isolated in a versioned/legacy section, which the judging guidance explicitly penalizes. This fits 'mostly efficient but could be tightened' better than the minor-trim bar of 4.

Actionability

Concrete, executable guidance throughout: "bundle validate --strict --target <target>", "databricks bundle validate --strict --target <target> --output json", the ".databricks/bundle/<target>/variable-overrides.json" path, and concrete patterns like "name: ${var.app_name}" and "<name>.<resource_type>.yml". Minor gaps remain because full YAML examples are deferred to reference files rather than shown inline.

Workflow Clarity

The Required App Completion Contract sequences re-read → structural checklist → validate --output json → inspect names → persist overrides and re-validate, an explicit feedback loop, and Guideline 1 mandates validation after every change. A 5 would require the main create→configure→validate→deploy workflow itself to be explicitly sequenced in the body rather than implied through sections and the reference-file ordering.

Progressive Disclosure

The body is a clear overview with five one-line-described references that all exist as real files one level deep (verified: no nested .md references inside them), plus external docs. Minor organization gaps hold it below 5: Guideline 7 duplicates the App contract content inline, and the "When to Use This Skill" section largely repeats the frontmatter description.

Specificity

"Create, configure, validate, deploy, run, and manage" lists six concrete lifecycle actions covering the domain comprehensively, with no vague filler. This matches the anchor for multiple specific concrete actions with comprehensive coverage; a 4 would require noticeable gaps in action coverage, which are absent.

Completeness

Explicitly answers what ("Create, configure, validate, deploy, run, and manage Declarative Automation Bundles") and when ("Use when working with Databricks resources via DABs including dashboards, jobs, pipelines, alerts, volumes, and apps") with concrete trigger phrases. This mirrors the top anchor exactly.

Trigger Term Quality

Good keyword coverage including synonyms users naturally say: "DABs", "Declarative Automation Bundles", "Databricks Asset Bundles", plus resource types (dashboards, jobs, pipelines, alerts, volumes, apps). A 5 requires synonyms and file extensions, but the common trigger "databricks.yml" is missing.

Distinctiveness Conflict Risk

Clear niche (Databricks resources via DABs) with distinct triggers; the "via DABs" scoping prevents overlap with generic Databricks or dashboard/job skills. Minimal conflict risk, matching the clear-niche anchor.
