# Databricks Core skill for Databricks CLI, authentication, and data exploration. ## Prerequisites `databricks --version` must report `v0.292.0` or newer. Installation is the user's responsibility; if the CLI is missing, run the command anyway and let the shell's `command not found` surface the problem to the user. **Authenticated:** `databricks auth profiles`. If empty: see [CLI Authentication](databricks-cli-auth.md). ## Profile Selection - CRITICAL **NEVER auto-select a profile.** 1. List profiles: `databricks auth profiles` 2. Present ALL profiles to user with workspace URLs 3. Let user choose (even if only one exists) 4. Offer to create new profile if needed ## Claude Code - IMPORTANT Each Bash command runs in a **separate shell session**. ```bash # WORKS: --profile flag databricks apps list --profile my-workspace # WORKS: chained with && export DATABRICKS_CONFIG_PROFILE=my-workspace && databricks apps list # DOES NOT WORK: separate commands export DATABRICKS_CONFIG_PROFILE=my-workspace databricks apps list # profile not set! ``` ## Data Exploration: Use AI Tools **Use these instead of manually navigating catalogs/schemas/tables:** ```bash # discover table structure (columns, types, sample data, stats) databricks experimental aitools tools discover-schema catalog.schema.table --profile <PROFILE> # run ad-hoc SQL queries databricks experimental aitools tools query "SELECT * FROM table LIMIT 10" --profile <PROFILE> # find the default warehouse databricks
