sigbound Runs Coding Agents in Parallel on One Repo and Only Merges Branches That Build and Pass Tests
GitHub·medium signal
A Go tool (created 2026-07-21, 94 stars) that fans multiple coding agents across git worktrees on a single repo and auto-merges their work — but gates every merge on a successful build and green test run, so failed agent output never lands. It sits on plain git with no proprietary state and is explicitly bring-your-own-model. This is the parallel-agent problem stated honestly: the hard part isn't running five agents, it's deciding which of the five diffs is allowed to survive.
