How is it related to Gemini CLI?

Dex ships a gemini-extension.json, so gemini extensions install https://github.com/exmergo/dex installs it from the latest release. It adds three Agent Skills for analytics engineering: explore a warehouse or DuckDB file read-only (profiles, PII flags, verified joins), author dbt models and semantic layers as reviewable diffs, and detect schema drift.
