What it does
A custom data analysis skill that already knows your warehouse: your tables, your metric definitions and your team's slang. Later questions get answers in your terms instead of generic ones. In build mode it connects to your database type, discovers schemas, and asks a short list of questions analysts usually keep in their heads: how revenue is defined, which tables to trust, what filters always apply. It writes the skill with reference files for each area. In improve mode you tell it what is missing about a topic, and it asks targeted questions and updates the right file. You will need database access and an analyst who knows the data.
