incident.io Runs 4-5 Parallel Claude Code Sessions as Default Workflow — Git Worktrees + Nimbalyst Desktop App for Visual Session Management

incident.io Blog·medium signal

incident.io's engineering team runs 4-5 parallel Claude Code instances as their standard workflow, each in isolated git worktrees with separate branches and full filesystem independence. Technique: use `claude -w` (--worktree) flag to create isolated worktrees automatically. Nimbalyst (formerly Crystal) is an open-source desktop app managing multiple AI coding sessions across worktrees with visual session tracking — review completed work in one session while Claude works in another.
