Pattern: Git-Worktree Isolation Converges as Standard for Multi-Agent Coding — Claude-Squad, Cursor, Claude Code All Ship It

Multiple (Claude-Squad, Cursor, Claude Code)·medium signal

Three independent tools now use git worktrees as the isolation primitive for parallel AI agents: Claude-Squad gives each agent its own worktree branch, Cursor 3.3 runs parallel build subagents in isolated workspaces, and Claude Code's native agent teams use worktree isolation by default (with v2.1.143 adding opt-out via bgIsolation: none). This convergence establishes worktrees as the standard unit of agent concurrency — one branch per agent, merge on completion.
