Spawn Claude Code teammates directly via the Agent tool's name param — no TeamCreate step
Claude Code Changelog·high signal
Claude Code's June 15, 2026 update removed the TeamCreate/TeamDelete tools; with CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 set, every session now has one implicit team and you spawn named teammates directly through the Agent tool. This collapses the old two-step flow (create a team, then add members) into a single inline call. For builders running agent fleets, parallel teammates can now be launched mid-task without pre-declaring the team.
