Skill builder. Tool-agnostic: works for any BI-to-BI migration (Looker to Lightdash, Tableau to Power BI, Metabase to anything). Detects what it can from your repositories, asks which tools you are moving between and what access Claude Code has (MCP servers, APIs, exports), then generates a custom /migrate-chart skill built around your exact source, target and conventions. Use when analysts should migrate their own reports instead of queueing for the data team.
