An analytics-engineering add-on for exploring a data warehouse, transforming data with dbt, and maintaining semantic models. A data warehouse is a store of collected business data, while dbt is a tool for building tested SQL transformations.

Use it to inspect warehouse data, create or update dbt models, define shared business meanings for metrics, and maintain transformations after schema changes.

It brings common warehouse and dbt maintenance work into the coding agent. It also addresses schema drift, where the structure of source data changes and can break transformations.

Security

Grade A, and why

dex scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

The scan reads gemini-extension.json. This mod also ships 19 executable files (scripts/build_docs_site.py, scripts/check_changelog_fragments.py, scripts/check_container_hardening.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
