What's Wrong?

Claude Code (Sonnet 4.5) repeatedly executed Bash commands in the background without disclosing this to me or obtaining my consent. This burned compute credits silently while I had no visibility into what was running or for how long.

During a git commit task with a slow pre-commit hook, the model silently retried the failing command 6+ times in the background. The user only discovered this through unexpected task notifications.

What Should Happen?

When a command fails, the model should stop, report what failed and why, and wait for user instruction before taking any further action. Commands should never be retried silently in the background without disclosure.
