Multi-Agent Coding Setups Are Mostly a Coordination Tax, Finds One-Month Experiment

After a month running parallel CLI coding agents on one prototype repo, the author concludes that for 90% of developers, multi-agent setups create more overhead than velocity. Each agent worked in an isolated checkout, blind to the other's changes, turning the author into a human merge resolver; separate git branches only delayed collisions to merge time, including a 20-minute hunt after one agent rewrote a utility another was importing.
Single-agent workflows on focused tasks remain rock solid. The real breaking point hits past three or four concurrent agents touching interdependent files — the threshold where standard branching breaks down and shared live runtimes like Tutti or unified state layers become necessary. The author asks where teams draw the line.
