Most developers run Claude Code sessions sequentially — one task
finishes, then the next one starts. That's a tool constraint,
not a task constraint. When your tasks are independent, your
agents should run in parallel.

Git worktrees solve this. One repo, multiple isolated working
directories, each on its own branch — each with its own Claude
Code session running simultaneously. Zero conflicts. Standard
git merge when done.

This video covers everything:
→ Git worktrees explained from scratch (no prior knowledge needed)
→ Why two Claude Code sessions in one directory breaks
→ Manual setup: git worktree add, list, remove
→ Claude Code's built-in --worktree flag (the fast path)
→ Live demo: two agents, one Solana repo, running simultaneously
→ Advanced: agent-vs-agent comparison, --tmux flag, CLAUDE.md scoping
→ .worktreeinclude for copying .env files into new worktrees
→ 5 gotchas: shared .env, migrations, dependencies, cleanup

Key commands:
git worktree add
git worktree list
git worktree remove
claude --worktree ← built-in Claude Code flag
claude --worktree --tmux ← launches in its own tmux session
