latex-diff

# LaTeX Diff > Compare two versions of a LaTeX document and report what actually changed — > text, equations, citations, labels/refs, section titles, macros, environments, > file add/remove, and moves — each graded by severity. Wraps the `latexdiff-agent` > CLI (`packages/latex-diff`). Member of the `latex-*` source/build family. ## When to Use - "What changed between these two versions of the paper?" - Building an R&R "summary of changes" or a preprint vN→vN+1 changelog - Focusing a re-review on the changes that matter (semantic-impact only) - Sanity-checking a co-author's edits before merging ## When NOT to Use - **Compiling** a document → `latex` - **Prose quality / proofreading** → `proofread` - A raw line diff is enough → `git diff` (this skill is LaTeX-aware: it knows a changed `\cite` key from a reflowed paragraph) ## What it produces Two views from the same canonical diff: 1. **Human summary** — grouped by file and section, every line carrying a change `id`, a severity badge, and a `file:line` location. 2. **Machine-readable JSON** — severity-graded `ChangeRecord`s. `semantic_impact: true` flags the changes a reviewer should actually read. For a persistent run inside a research project, these are the mandatory core files. Use one timestamp-only basename for the whole run: ```text reviews/<scope>/<check>/<YYYY-MM-DD-HHMM>.md reviews/<scope>/<check>/<YYYY-MM-DD-HHMM>.changes.json ``` Here and below, `<check>` is this skill's frontmatter `name`.
