The article outlines a mobile development setup using Claude Code agents, enabling coding on a phone without needing a traditional computer. The author runs six Claude agents in parallel on a cloud VM hosted by Vultr, using Termius for SSH access and Tailscale for a private network. The VM costs $0.29 per hour, and access is tightly controlled through Tailscale, which eliminates public SSH exposure. Two scripts automate starting and stopping the VM, allowing the author to manage it directly from their phone using an iOS Shortcut. Key to this setup is mosh, a mobile shell that maintains connections across different network conditions. This allows the author to switch between WiFi and cellular without losing the session. They also utilize tmux for session persistence, ensuring that work remains intact even after closing the Termius app. Push notifications are a crucial feature, alerting the developer when Claude needs input, which helps to integrate coding tasks into a busy schedule. The author employs git worktrees to manage multiple feature branches simultaneously, with each branch running in its own tmux window and associated Claude agent. Port allocation is determined by a hash function based on the branch name, preventing conflicts. This setup enables the developer to review pull requests, start refactors, or fix bugs in short timeframes, efficiently fitting programming into daily routines. The whole system was developed in one session with Claude Code, emphasizing the streamlined nature of the process.
