[jjaiwant328]

Summary

• Adds databricks-powerbi-migration skill for migrating Power BI semantic models to Databricks metric views
• Restructured with progressive disclosure pattern (matching SDP skill): concise SKILL.md (164 lines) + 9 numbered guide files for detailed per-phase instructions
• 16-step guided workflow covering: input scanning, PBI model parsing, catalog validation, schema extraction, mapping layer construction, ERD/domain generation, KPI definitions, data discovery, query optimization, existing metric view detection, metric view creation, report analysis, and deployment checklist generation
• Includes 6 Python/Bash utility scripts for automated parsing, comparison, and scaffolding
• Supports all PBI model formats (.pbit, .pbix, .bim, TMDL, JSON) via content-based detection
• Handles 4 migration scenarios (direct repoint, view layer, mapping document, intermediate mapping)
• Supports parallel catalog probing via shell subagents and batched SQL via execute_sql_multi

Files Added

• databricks-skills/databricks-powerbi-migration/SKILL.md -- main skill entry point (164 lines, progressive disclosure)
• databricks-skills/databricks-powerbi-migration/1-input-scanning.md through 9-subagent-patterns.md -- 9 detailed guide files
• databricks-skills/databricks-powerbi-migration/REFERENCE.md -- detailed patterns for 15 identified gaps
• databricks-skills/databricks-powerbi-migration/EXAMPLES.md -- input/output examples
• databricks-skills/databricks-powerbi-migration/README.md -- usage overview and script documentation
• databricks-skills/databricks-powerbi-migration/approach.md -- high-level methodology
• databricks-skills/databricks-powerbi-migration/scripts/ -- 6 utility scripts

Files Modified

• databricks-skills/README.md -- added skill to Analytics & Dashboards section

Test plan

• Installed locally via install_skills.sh --local databricks-powerbi-migration
• Verified skill loads in Claude Code via /databricks-powerbi-migration
• Verified description-based routing triggers on Power BI migration prompts
• SKILL.md under 500 lines (164 lines)

• No credentials or secrets in any file
• Passed Databricks pre-commit and pre-push secret scanning hooks

I like the idea and think it looks great, but I'm requesting a review from @calreynolds or @dustinvannoy-db, as it's entirely new and we don't have migration skills right now.

[calreynolds]

We will get back to you! We're debating whether we want to include anything third-party or not

My content feedback would be: I think we can trim this generally!

Also, can you adjust the file structures to be similar to how we do spark-declarative-pipelines? The more uniform, the easier for the llm to digest

Thank you for the feedback. Will follow up on this and let you know when I am done. Also it is more of a PowerBI to Databricks migration, but because of the naming convention it is confusing. Let me know if you want me to change it.
