The author polled several subreddits on preventing parallel AI agents from stepping on each other in one repo, distilling 60 replies. Git worktrees are a near-unanimous code-side fix; the real work is runtime isolation — per-worktree environments, ports derived from branch names, seeded throwaway databases, teardown in task definitions, and a single verify command agents can run themselves. Persistent failure points: shared Redis/queues get forgotten, background workers outlive sessions and run old code, and all setups are hand-fitted to specific stacks. Skeptics outside AI subs call it an old multi-dev problem renamed.
