Description

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 problems:- Dex forces the agent to use a cost guard when performing exploration queries and transformations.- Dex uses a set of tooling that makes it hard to get burned when transforming data.It achieves these things with tight control scripts that the SKILL.md files are pointed towards when using /dex:explore, /dex:transform and /dex:maintain.Bonus: Dex makes agents really good data exploration, building sql and dbt models and detecting drift. 76% performance on ade-bench with Claude Sonnet 5 (and, per our measures, 2.5x cheaper than Fable 5).Install on any agent with this command in your terminal:npx skills add exmergo/dexInstall on Claude Code running these commands (separately):/plugin marketplace add exmergo/exmergo-agent-plugins/plugin install dex@exmergoIf you want to see more visual examples you can go through the README or browse here: https://www.exmergo.com/dexLet me know if this helps your analytics workflow and makes your agents more cost-aware.
