r/AI_Agents: Unattended Claude Code Session Fills 632 GB SSD Overnight With Unconstrained File Output

A developer left Claude Code running overnight on an unattended task and woke to a nearly full 632 GB SSD, with no built-in disk-usage limit or automatic stop condition having triggered. The post is drawing engagement from builders who recognize unconstrained file-output accumulation as an underexplored failure mode in long-running agent sessions. Discussion is converging on filesystem sandboxing, per-session storage quotas, and the absence of resource enforcement in current Claude Code harnesses as practical mitigations.
