I am building a coding harness, and I see evidence of them doing this with agentic harnesses and scaffolding. It feels clear to me that as they expand in to the app layer, the window of using their API to build agentic apps is closing, they will steal your ideas, implement the product and then close the gate. I am creating my own inference stack because their incentive to block competitors is becoming super clear.
No offense, but the sad thing is, everyone and their mother is working on this same problem. I'm also building a harness. It's feeling like, there is no moat, there is no way to get ahead, they will steal your idea one way or another, if you ever make it public.
