How to Run Claude Code Agents for 24+ Hours

Running AI coding agents for extended periods is crucial for maximizing engineering productivity by minimizing human review time, which has become the primary bottleneck. To achieve long-running sessions, agents should be granted full permissions within a secure, sandboxed environment to prevent interruptions from permission requests. It is also vital to enable agents to verify their own work by providing detailed instructions and tools for self-testing, such as comparing implementations against design mockups. The process can be further improved by using agentic code reviews, where one AI reviews another's work, and by running agents remotely to ensure they operate without interruption.
