Check References

• Every picture and table needs a label and a caption, and must be referenced in the text
• Captions should only say what is done. Comments and other content go in the text

Add Captions and Labels

• For all figures in the LaTeX files in the passed dir, add the caption and label to the commented section.

• For instance convert

  %     ```
  % rendered_images:end
  % render_images:begin
  \begin{figure}[!ht]
    \centering
    \includegraphics[width=\linewidth]{figs/02_architecture.1.png}
    \caption{Confounding adjustment in causal inference}
    \label{fig:confounding_adjustment}
  \end{figure}
  % render_images:end
  

  to

  %     ```
  % caption=Confounding adjustment in causal inference
  % label=fig:confounding_adjustment
  % rendered_images:end
  % render_images:begin
  \begin{figure}[!ht]
    \centering
    \includegraphics[width=\linewidth]{figs/02_architecture.1.png}
    \caption{Confounding adjustment in causal inference}
    \label{fig:confounding_adjustment}
  \end{figure}
  % render_images:end
  

Create Labels and Captions From Scratch

• If a figure has no caption or label, infer them from the filename and surrounding context
  • E.g., figs/02_architecture.1.png becomes label=fig:architecture, caption=System architecture overview
• Use short, lowercase label names with underscores

Add References in the Text

• If a figure has a label but no citation in the text, add a parenthetical reference near the most relevant paragraph:

  (see Fig.~\ref{fig:confounding_adjustment})
  

Verify No Orphaned References

• Scan the text for \ref{fig:xxx} or \ref{tab:xxx} with no matching \label in any figure or table environment
• Report orphaned references as warnings. Do not silently delete them

Verification

• Every figure and table has a \label and a \caption
• Every figure and table \label is referenced by a \ref in the text
• No orphaned \ref{fig:xxx} or \ref{tab:xxx} exists without a matching \label in any figure or table environment
