Opus 4.6 + Agent Teams Makes Claude Code Insane

Claude Code’s Agent Teams feature has transitioned from a hidden hack to an official experimental release, introducing a sophisticated swarm architecture where specialized sub-agents collaborate on complex development tasks. Unlike traditional sub-agents that merely report to a lead, these teammates possess independent contexts, share a unified task list, and can communicate or argue with one another to refine outputs. Integration with Tmux and iTerm2 allows for real-time monitoring of parallel workflows through split-pane interfaces, as demonstrated by the simultaneous creation of a web interface and UI styling for a video downloader tool. While powerful, the architecture is highly resource-intensive; a single session involving two teammates can consume nearly 30% of a high-tier usage limit, totaling approximately 13,000 tokens. This high operational cost likely restricts the feature's practical application to specialized research or rigorous cross-agent code auditing rather than routine daily development.
