swyx on Anthropic's 'ultracode': 'Scarily Good at Burning Tokens' — but Only If You Architect Your Repo for Subagent Fanout
swyx says few outside Anthropic have tried 'ultracode' yet, calling it extremely capable but token-hungry, and warns the payoff only materializes if you set up your repo so subagents can parallelize — 'subroutines but intelligent.' The tactical takeaway is that value now comes from structuring codebases for fanout, not just from a better model. It reinforces his broader 2026 thesis that coding agents are 'breaking containment' to do everything else.
