Show HN: Dex – Cost-aware analytics engineering skills for agents

Hi I’m Marco, co-founder of Exmergo.<p>Me and my team created Dex to help Analytics Engineers do real work with Claude Code (and any other coding agent).<p>We’ve found that Data and Analytics teams are stuck between a rock and a hard place cost-wise:<p>- On one side, they are using some of the most expensive consumption-billed software on the planet (Snowflake, Databricks etc.).<p>- 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).<p>So we created Dex, our open source skills plugin (Apache-2.0), to solve both of these problems:<p>- Dex forces the agent to use a cost guard when performing exploration queries and transformations.<p>- Dex uses a set of tooling that makes it hard to get burned when transforming data.<p>It achieves these things with tight control scripts that the SKILL.md files are pointed towards when using &#x2F;dex:explore, &#x2F;dex:transform and &#x2F;dex:maintain.<p>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).<p>Install on any agent with this command in your terminal:<p>npx skills add exmergo&#x2F;dex<p>Install on Claude Code running these commands (separately):<p>&#x2F;plugin marketplace add exmergo&#x2F;exmergo-agent-plugins<p>&#x2F;plugin install dex@exmergo<p>If you want to see more visual examples you can go through the README or browse here: <a href="https:&#x2F;&#x2F;www.exmergo.com&#x2F;dex" rel="nofollow">https:&#x2F;&#x2F;www.exmergo.com&#x2F;dex</a><p>Let me know if this helps your analytics workflow and makes your agents more cost-aware.
