description	When editing `.tex` files, use this skill as often as possible. When rewriting `.tex` content spanning more than a few words, comment out the original and write the replacement below it so the user can review the before/after diff directly in the source.

Annotated Rewrite

When rewriting .tex file content (paragraphs, sentences, equations, list bodies, or any block larger than a few words), preserve the original by commenting it out rather than deleting it, then write the replacement below. This lets the user review exactly what changed before accepting the edit.

When to apply

Default to this pattern whenever the replaced content is more than a short inline phrase (see the word-level exception below), regardless of content type — prose, equations, lists, environment bodies, or any contiguous block. Use it as often as possible — when in doubt, use it.

A useful guide: if the replaced content is 3 or more source lines, always apply it. For shorter replacements (1-2 source lines), lean toward applying it unless the change is purely word-level: replacing a single word, fixing a typo, or changing a run of 1-5 words within an unbroken clause.

Word-level edits are the only case where skipping the annotated format is clearly appropriate (subject to the structural exceptions in Rule 8).

Edit format

% [original]
% The proposed method encodes user history as a fixed-length vector,
% then applies a linear projection before computing dot-product scores.
% Training uses binary cross-entropy loss over sampled negatives.
%
% \begin{equation}
%   \hat{y}_{ui} = \mathbf{u}_i^\top \mathbf{v}_j
% \end{equation}

% [revised]
We encode user history with a transformer encoder, producing a
context-aware representation that is projected into the item space.
Training minimises a softmax loss over in-batch negatives.

\begin{equation}
  \hat{y}_{ui} = \mathrm{softmax}(\mathbf{U}\mathbf{V}^\top)_{ij}
\end{equation}

Rules

1. Copy the original lines verbatim into the comment block — do not alter them
2. Include every line of the replaced content verbatim with % prepended; blank lines within the block become % empty-comment lines (a line containing only %). Include \begin{...} / \end{...} markers only when they are part of the replaced content — do not comment out enclosing environment markers that are not themselves changing
3. No blank line between % [original] and the first commented line
4. One blank line between the last commented line and % [revised]; one blank line before % [original] and after the last line of the replacement (to separate the annotated construct from surrounding document text)
5. The new content after % [revised] is normal LaTeX (not commented)
6. For multiple non-adjacent replaced blocks, apply the pattern independently to each block
7. Idempotency: if the content being edited already contains a % [original] / % [revised] block, edit only the active content after % [revised] — do not re-wrap the existing annotated block or create a new outer annotation around it
8. Structure safety: only apply this pattern at block level (paragraph, sentence, equation block, list body, or environment body). Do NOT insert % [original] / % [revised] inside macro arguments, table rows, math expressions, \caption{...}, \item[...], or preamble commands — make minimal direct edits there instead, or ask for confirmation before changing structurally sensitive content
