Dex by Exmergo

What it does

Install it into Claude Code, Codex, Cursor or Gemini CLI, then point it at your warehouse and dbt project. Dex maps the schema read-only behind a cost guard, authors models and metrics as diffs you review, and tells you what broke when things drift. Also a Python package. npx skills add exmergo/dex

Analytics engineering for Claude Code and any agent: data warehouse exploration, dbt transformation and semantic modeling, and schema-drift maintenance on dbt.

Point it at your warehouse and your dbt project. It learns the landscape, authors your transformations, and tells you exactly what to fix when the schema drifts. products.brand column no longer found. Closest matches: brand_name, manufacturer_name Two meters run on every query an agent writes. Dex is made to hold both of them down. Snowflake and Databricks are some of the most expensive consumption-billed software on the planet. An agent left to explore freely explores on your credit card. Anthropic and OpenAI bill by the token, and nothing burns through a context window faster than data analytics. One unguarded schema dump can cost more than the query it was meant to plan. Both come from…from exmergo.com

  Dex – Cost-aware analytics engineering skills for agentsJul 2026 · github.com · ▲5

  Hi I’m Marco, co-founder of Exmergo. Me and my team created Dex to help Analytics Engineers do real work with Claude Code (and any other coding agent). We’ve found that Data and Analytics teams are stuck between a rock and a hard place cost-wise: - On one side, they are using some of the most expensive consumption-billed software on the planet (Snowflake, Databricks etc.). - On the other side, Anthropic and Open AI want you to tokenmax (and with data analytics it’s very easy to burn your context window). So we created Dex, our open source skills plugin (Apache-2.0), to solve both of these…

  Auto-document your analytics setup (npx package)2024 · github.com · ▲17

  Hey HN, sharing an npx package that I’ve been working on to help teams automatically document their analytics setups. It crawls any JS/TS codebase and generates a YAML schema that catalogs all the events, properties, and triggers. Currently supporting GA, Amplitude, Mixpanel, Amplitude, Rudderstack, mParticle, PostHog, Pendo, Heap, Snowplow. Let me know if there’s any more I should add to the list! Came out of a personal pain where I was struggling to keep tabs on all the analytics events we had implemented. The “tracking plan” spreadsheets just weren’t cutting it, and I wanted…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
