Review returns Markdown with four sections: Summary, Critical, Warnings, and Suggestions. Critical items are issues that can throw, corrupt data, or execute untrusted input. Warnings are likely bugs. Suggestions are maintainability notes.
Review looks for empty-list division, `== null` / `== None`, `eval` / `exec` / `innerHTML`, and TODO/FIXME markers. If nothing matches, you still get maintainability notes that reference identifiers from your snippet.
Use findings as a checklist. Confirm line locations in your editor. Discard anything that does not apply. Human judgment and tests still matter.
