It sounds like a gate is a prompt that shows up at the appropriate time, which works because LLM’s pay more attention to the last thing they read.

It seems like a lot of coding agent features work that way?

I suppose, I mean the LLM is still reading it, the issue is, Beads gives the model a task, and then the model finishes, and never checks anything. I kept running into this repeatedly, and sometimes I'd go to compile the project after it said "hey I finished" it wouldn't compile at all, where if it would have just tried to build the project, it would have just worked.
