Claude Code's June 19 release finally blocks the "agent nuked my uncommitted work" failure.

Auto Mode now blocks destructive git commands (reset --hard, checkout -- ., clean -fd, stash drop) when you didn't ask to discard work, blocks git commit --amend on commits the agent didn't make this session, and blocks terraform/pulumi/cdk destroy unless you named the specific stack (Releasebot). If you run agents unattended overnight, this is the guardrail you've been hand-rolling. The same release also fixes subagent, WebSearch, and background-task bugs.
