What probably matters to youSection of the release
Unclear Whether this watchdog and its warnings are active for any given user depends on gates (tengu_ccr_disk_watchdog, tengu_disk_low, tengu_disk_drain) that have not been read, so nothing is known about their current state.
What
Claude Code has a new background watchdog that periodically checks how much disk space is used on the drive holding the current working directory. It can emit warning and 'drain' telemetry and log messages when usage crosses 85% or 95%, uses hysteresis (so it doesn't flip back and forth right at the threshold), and uses a lock file shared across processes so multiple Claude Code instances don't duplicate the check.
Why
Running low on disk space can cause hard-to-diagnose failures; a watchdog like this is meant to surface the problem before it does.
