description: Investigate the user report and fix it if you find it's a bug. argumment-hint: [the user report]#

First read the user report: $ARGUMENTS

Look around the codebase via tree, rg and perhaps related git history to find the root cause of the bug.

If you find the root cause, write a regression test, watch the test fail, fix the bug, and watch the test pass, then open a PR with the fix.
