CLAUDE_CODE_LOOP_PERSISTENT

Updated October 13, 2026 by Alex Sorokoletov

CLAUDE_CODE_LOOP_PERSISTENT is a Claude Code environment variable: Persist loop state across session boundaries. Loops don't die when the session restarts — they resume. Turns /loop from a within-session tool into a durable recurring task mechanism. Combine with a cron-style trigger for genuinely automated periodic Claude Code jobs. Added between v2.1.128 and v2.1.138 and still present in v2.1.294. It is not in the official reference.

claude

To apply it to every session, add it to the env object of a settings file:
