Running several coding agents in parallel creates a review problem before it creates a compute problem.
The bottleneck is rarely opening another terminal. The bottleneck is deciding which session deserves attention, who owns each change, and what evidence is sufficient to accept the result.
A wall of chat windows does not answer those questions. A team lead needs a queue of owned artifacts and review decisions.
Partition work before parallelism
Every task should have one owner, one requested artifact, and one write scope. If two sessions may edit the same file, decide who integrates the final change or serialize the work.
