+@copilot Review commits and PRs merged or opened in the last 7 days and open issues in stanfish06/my-configs. For each change, check for:
+
+1. Information leaks — secrets, API keys, tokens, personal emails/paths, private hostnames, or anything that shouldn't be public.
+2. Compatibility breaks — config syntax that may be obsolete, deprecated flags, broken references between files, or changes that could break dotfile/script consumers.
+3. Improvement opportunities — new features, config options, or fixes worth adopting based on upstream tool updates.
+
+For each finding, open a GitHub issue (try to send a PR with the fix if low-risk and you are confident about the patch). Never commit directly to master — always open a PR. Group related findings into a single issue/PR when sensible. If nothing actionable is found, do nothing.
+
+Files to ignore:
+1. .emacs (all emacs configs in the repo can be ignored as they are actively maintained)
