Plain language
A commercial AI assistant marketed as an autonomous software engineer.
As stated in the literature
An agentic coding product positioned as an autonomous software-engineering agent, cited as a representative production deployment of long-horizon coding agents.
Why it matters: It represents the real-world push toward agents that handle long software tasks end to end, raising the stakes for how reliable such agents must be.
For example, it is pitched as a tool you can hand a coding task and let it work through the steps on its own like a junior engineer.
