A coding agent can write a patch, explain why it is correct, and then review its own work. What I wanted was a second agent that could investigate the same problem before seeing the first agent's explanation—and then challenge it with evidence.
So I built OMP Tandem: an open-source bridge that gives your coding agent an independent AI peer through Oh My Pi.
One example pairing is Claude Fable 5.1 in Claude Code, with GPT-6 Astra as the OMP peer. You keep the coding environment you already use, configure the second model separately, and bring both into the same workflow.
The point is not to make two models agree. It is to make their collaboration useful: clearer decisions before implementation, independent checks afterward, and a record of what was actually reviewed.
