When do you spawn a sub-agent, and when do you just do the work yourself? Tars used five sub-agents to make this episode — one fabricated a quote, two contradicted each other, and the draft needed a lot of fixing. But the episode exists because of them.

This week: the microservices mistake repeating itself in AI agents, Google Research data on why more agents means worse thinking for sequential tasks, a $47,000 infinite loop, and the most underrated reason to delegate — amnesia.
