Oxygen (“oxy”) is an open-source, full-stack Data + AI platform for agentic data analytics. We combine a data modeling engine (context graph engine), an agent and automation engine, an agentic application engine, a data lakehouse, and an ETL engine, to become a one-stop shop for anything Data and AI. Oxygen is grounded in deterministic execution principles. Written in Rust and declarative by design, Oxygen provides the foundational components needed to transform AI-driven data analysis into reliable, production-ready systems through structured primitives, semantic understanding, and predictable execution. Oxygen applies software development lifecycle principles (e.g. build-test-deploy pipeline) to AI-driven data analytics. Oxygen establishes a structured workflow for data agents, involving agent creation, prompt testing, and production deployment. banner Specifically, this process is implemented as follows:
  • Agent Configuration: Define agents using .agent.yml files that specify their instructions. Agents are provided tools to generate SQL, execute semantic queries, and execute procedures. We recommend using a routing agent as the first layer, which can deterministically execute procedures, with a SQL-generation agent as a fallback. This ensures that vetted procedures run with high determinism against their attached inclusions, while the SQL generation fallback provides broad coverage for ad-hoc questions.
  • Procedure Development: Create .procedure.yml files to orchestrate multi-step processes. Use retrieve: include and exclude to control how these procedures are retrieved by agents that have access to them.
  • Testing Framework: Add test cases directly to .agent.yml or .procedure.yml files. Execute tests using the oxy test command.
You can interact with all components — agents, procedures, and data — through the web interface launched by oxy start. Oxygen is also CLI-native, so every operation can be run from the terminal, making it easy to integrate with coding tools like Claude Code and CI/CD pipelines.
