Dex is the agent-native analytics engineering toolkit. 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. Built for analytics engineers and data engineers who want more out of their coding agent.

Cost guardrails for Snowflake queries when agents token-max and burn your budget.

Strengths

•PII-aware query firewall prevents sensitive data leaks into agent context
•dbt-first approach treats projects as first-class objects, not afterthoughts
•Three focused commands (explore/transform/maintain) map to real AE workflows

Weaknesses

•Only 8 stars suggests untested in production despite bold claims
•Agent skills plugin pattern is becoming crowded with similar tools

Post 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/dex

Install on Claude Code running these commands (separately):

/plugin marketplace add exmergo/exmergo-agent-plugins

/plugin install dex@exmergo

If you want to see more visual examples you can go through the README or browse here: https://www.exmergo.com/dex

Let me know if this helps your analytics workflow and makes your agents more cost-aware.

LLM-use – cost-effective LLM orchestrator for agents

Smart local‑first routing that only escalates to expensive cloud planners when necessary is the standout idea — combined with per‑run cost accounting and full Ollama offline support it solves a real operational itch. The repo is a pragmatic, CLI/TUI-focused toolkit (scraping + cache, MCP server mode) that feels useful for teams wanting a no‑friction orchestrator, but it’s playing in a crowded space of agent frameworks so the novelty is incremental rather than revolutionary.
