Dex is an open-source CLI that lets your agent build your analytics. It comes with skills out of the box. Install it in any coding agent, then point it at your data. Dex does ETM: Explores the landscape → Transforms your data into models and metrics → Maintains them by fixing drift before it reaches production.
This is the 2nd launch from Dex by Exmergo. View more
Dex Semantics
Launching today
Dex Semantics adds declarations to your analytical models, which capture row meaning, join nature, how numbers add up, and decisional assumptions.
Thanks to this, Dex scores 80% on ADE-bench with Claude Sonnet 5.5, compared to 73.3% without Dex (25% fewer tasks failed).
Declarations live in your models as code, not a third-party tool. Dex then helps your agent convert declarations into your Semantic Layer of choice.

Hey everyone, I think this quote neatly describes the problem we're solving.
It's acutely painful in the context of analytics, where one wrong (but plausible) number can steer a giant enterprise or a fast-growing startup in the wrong (and disastrous) direction.
And, of course, the problem's magnitude is amplified by the speed of development brought about by agents.
Thank you @fmerian and @gtmnerd!
I like that you're keeping semantic definitions close to the actual code, i think it help optimize SQL queries as well.
@priya_kushwaha1 Definitely!
Really interesting to see a toolkit addressing both the intelligence and reliability sides of AI-driven analytics. Those two things need to go together.
@tehreem_fatima5 Very well put
Let's goooooo!
@gtmnerd I ♥️ GTM
keeping how numbers add up right next to the model is the right place for it, a summed ratio looks totaly plausible on a dashboard and nobody notices
when a declaration goes stale after a schema change, does Dex flag it before the agent relies on it??? feels like the obsolete assumption from your quote all over again
@thamibenjelloun 100%, that's what the `dex maintain` commands are all about!
You can run the maintain commands in agentic workflows or in CI, to make sure that a schema change gets flagged. Your agent can then check the declared assumptions vs the schema drift and update the data models (and declarations) accordingly!
