Databricks just open-sourced the layer above every agent harness. Your sessions, policies, and skills survive model swaps now.

Every coding agent you use is a silo.

Claude Code, Codex, Pi, Cursor — each one owns its sessions, its controls, its way of running.

None of it carries over when you switch tools.

Omnigent just killed that problem.

Built by Matei Zaharia's team at Databricks and open-sourced under Apache 2.0, Omnigent is a meta-harness — a common orchestration layer that sits above the agents you already use.

The key insight is simple: every harness calls into its LLM differently internally, but the interface to users is identical — messages and files in, text streams and tool calls out.

Omnigent wraps that interface. One API. Any harness. One-line swaps between Claude Code, Codex, Pi, and custom agents.

What it adds:

— Real-time collaboration: share a live session via URL, co-drive from any device, fork conversations to continue independently

— Contextual security policies: not just "allow X / deny Y" — policies that track dynamic state. After an agent downloads an npm package, require human approval to git push. After $100 spent, pause and ask.

— Cost budgets per session, enforced at the meta-harness layer, not via prompts

— OS sandbox with network interception — inject GitHub tokens only in the egress proxy on approved requests, never expose them to the agent

— YAML-defined agents with sub-agents and reviewers. Agents can build agents.

— Deploy anywhere: Docker, Fly.io, Railway, Modal, Daytona sandboxes. Sessions reachable from your phone.

The GitHub repo: github.com/omnigent-ai/omnigent — 3.8K stars, 425 forks, Python + TypeScript, Apache 2.0.

This changes the abstraction you build at.

Stop writing agent logic that dies when you switch harnesses.

Write policies, sessions, and skills at the meta-harness layer. They follow you across models and providers.

Your next agent project should be harness-agnostic from day one.
