No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends

Quiet. No reports and thumbs-up in the last two weeks, down from 224 a week at the late-September peak. A workaround is known.

Console windows pop up for each spawned command on Windows. Blank CMD, PowerShell or Windows Terminal windows flash and steal focus when submitting prompts and during command execution.
