According to Boris Cherny on Twitter, Claude subagents now support Git worktree isolation to execute tasks in parallel, which is particularly effective for large batched changes and code migrations; Cherny notes it is available across CLI, desktop app, and IDE clients. As reported by Boris Cherny, asking Claude to use worktrees enables concurrent branches with isolated file systems, reducing merge friction and improving throughput for repository-wide refactors. According to the tweet, this expands practical applications for enterprise-scale monorepos and continuous delivery pipelines, creating business opportunities for faster migration sprints, safer feature flag rollouts, and automated codemod campaigns.

According to OpenAI on Twitter, the Codex app allows users to multitask by working with multiple agents in parallel, keeping changes isolated using worktrees. The app also lets users create and use skills by packaging tools and conventions into reusable capabilities. Additionally, Codex supports setting up automations to delegate repetitive tasks, streamlining workflow and increasing productivity. As reported by OpenAI, these features highlight the app's focus on practical applications and business efficiency in AI-driven environments.
