Agentic OS · internal codename ECC · private beta

The agent harness operating system.

Your coding agent can already write code. Agentic OS gives it a coordinated engineering system: it plans before it builds, verifies with tests, reviews its own work from a fresh context, remembers what matters, and turns repeated wins into reusable skills.

02 / The five capabilities

Five things a harness has to do.

None of them are model capabilities. All of them are systems work — which is why the harness, not the model, is where the reliability comes from.

03 / The registry

Every agent, skill, and rule in one place.

Not a prompt library — a governed inventory. Each agent declares its model and its exact tool permissions, so you can see what is installed and what it is allowed to touch before it ever runs.

04 / Fits your stack

Agent-agnostic, on purpose.

Keep the coding agent your team already trusts. Agentic OS sits above it, not instead of it — so switching models never means switching process.
