IDE-centric tooling assumes a human in the editor, which is the wrong center of gravity once agents do most of the editing.
Steering long-running agents needs surfaces for both synchronous and asynchronous work.
Model and harness are usually developed by different teams and integrated late.

A standalone, agent-first desktop app with no IDE, built to steer and orchestrate coding agents both synchronously and asynchronously.
Launched at Google I/O 2026 alongside a CLI, SDK, and API, sharing one harness across surfaces.
Explicitly states that the product's agent harness, agent layer, and Gemini model layer were co-optimized and co-developed.

It is the primary vendor source articulating model-harness co-optimization as a design thesis — the "an agent = model + harness" framing stated as a product decision rather than an observation.
It is the clearest Google representation of the shift from IDE-centric to orchestration-centric tooling.
Caveat: a vendor product announcement. Co-optimization claims and any performance figures are Google-reported and not independently validated; third-party syntheses restate launch specifics that should be confirmed against Google's primary sources.
