The Meta-Harness: Why Every AI Developer Needs This

Thanks to Databricks for early access and making this video possible through their sponsorship. You use Claude Code, Codex, and Pi separately — copying context between them because no agent can see the others. In this video I break down the meta-harness: a single layer that sits above every harness so all your agents share one session, one history, and one set of policies — and even review each other's code across vendors (Claude writes, Codex reviews). I walk through OmniGent, the Apache-2.0 meta-harness Databricks just open-sourced, and build a real app with it live.
