Descriptions:
Bart Slodyczka runs a structured side-by-side experiment comparing Claude Code’s single-agent mode against the new agent teams feature using Opus 4.6, giving both instances the same prompt — build a task manager web app — and documenting how each approaches the problem. The comparison makes the architectural differences tangible rather than theoretical.
The video clearly explains what separates agent teams from sub-agents: sub-agents operate within the parent session’s token budget and return only final results, while agent team members each spin up their own independent Claude Code instance with dedicated token allocation. Team members can communicate laterally with each other — not just transactionally up to the team lead — enabling more dynamic collaboration on complex, multi-component builds. Anthropic’s own framing is cited: sub-agents suit focused, bounded tasks; agent teams suit problems requiring broad coverage or diverse analytical perspectives.
The live demo shows the team lead breaking the task into discrete components (HTML/CSS structure, JavaScript logic), spawning specialized agents for each, and progressively creating new agents as work completes. Bart demonstrates navigating between team lead and individual agents in real time using tmux keyboard shortcuts. The finished task manager — featuring priority tags, due dates, project categories, and a day/night mode toggle — serves as a concrete artifact for comparing single-agent versus team output quality. The setup instructions, including the required settings.json configuration, make the tutorial immediately reproducible.
