Latex Document

LaTeX Document Skill

Create any LaTeX document, compile to PDF, and generate PNG previews. Convert PDFs of any type to LaTeX.

Workflow: Create Documents

1. Determine document type (resume, report, letter, invoice, article, thesis, academic CV, presentation, poster, exam, book, cheat sheet)
2. If poster: Run the poster sub-workflow (see Poster Sub-Workflow below), then skip to step 5.
3. If cheat sheet / reference card: Run the cheat sheet sub-workflow (see Cheat Sheet / Reference Card Sub-Workflow below), then skip to step 5.
4. Ask the user which enrichment elements they want (use AskUserQuestion tool with multiSelect). Offer relevant options based on document type:
   • AI-generated images -- custom illustrations, diagrams, photos (uses generate-image skill)
   • Charts/graphs -- bar, line, pie, scatter, heatmap (pgfplots or matplotlib)
   • Flowcharts/diagrams -- process flows, architecture, decision trees (TikZ or Mermaid)
   • Citations/bibliography -- academic references, footnotes, works cited (BibTeX/biblatex)
   • Tables with data -- comparison matrices, financial data, statistics (booktabs)
   • Watermarks -- DRAFT, CONFIDENTIAL, or company logo background
   • Skip this step for simple documents (cover letters, invoices) or when the user has already specified exactly what they want.
5. Copy the appropriate template from assets/templates/ or write from scratch
6. Customize content based on user requirements
7. Generate external assets based on user's element choices:
   • AI images: python3 <skill_path>/../generate-image/scripts/generate_image.py "prompt" --output ./outputs/figure.png
   • matplotlib charts: python3 <skill_path>/scripts/generate_chart.py <type> --data '<json>' --output chart.png
   • Mermaid diagrams: bash <skill_path>/scripts/mermaid_to_image.sh diagram.mmd output.png
8. For documents 5+ pages: Review the Long-Form Document Anti-Patterns section and run the Content Generation Checklist before compiling. Key rules: prefer prose over bullets, include global list compaction, escape </> in text mode, vary section formats, limit ewpage, size images at 0.75-0.85 textwidth.
9. Compile with scripts/compile_latex.sh (auto-detects XeLaTeX for CJK/RTL, glossaries, bibliography)
10. Show PNG preview to user, deliver PDF

Poster Sub-Workflow

When the user requests a poster: read references/poster-design-guide.md for the complete workflow including conference size presets (NeurIPS/ICML/CVPR/ICLR dimensions), layout archetypes (Traditional/BetterPoster/Visual-Heavy), color schemes, and typography standards. Use poster.tex (portrait) or poster-landscape.tex (landscape). Ask the user for conference/orientation, layout style, and color scheme using AskUserQuestion, then proceed to step 5.

Cheat Sheet / Reference Card Sub-Workflow

When the user requests a cheat sheet, reference card, or formula sheet:

1. Read references/cheatsheet-guide.md for the complete workflow including template selection, content budgets, typography rules, and the PDF-to-cheatsheet pipeline.
2. Select template: cheatsheet.tex (general, 3-col landscape), cheatsheet-exam.tex (exam formula, 2-col portrait), or cheatsheet-code.tex (programming, 4-col landscape).
3. Follow the guide's workflow steps, then return to main workflow step 5.

Workflow: Mail Merge (Batch Personalized Documents)

Generate N personalized documents from a LaTeX template + CSV/JSON data source using scripts/mail_merge.py. Template syntax: {{variable}} for simple substitution, Jinja2 (<< >>, <% %>) for conditionals/loops. See assets/templates/mail-merge-letter.tex for an example. Full guide: references/interactive-features.md.

Workflow: Version Diffing (latexdiff)

Generate highlighted change-tracked PDFs using scripts/latex_diff.sh. Supports file-to-file diff, git revision diff, multi-file flatten, and custom markup styles. Full guide: references/interactive-features.md.

Workflow: Convert Document Formats

Convert between Markdown, DOCX, HTML, and LaTeX using scripts/convert_document.sh. Full guide: references/format-conversion.md.

Workflow: Convert PDF to LaTeX

Convert existing PDFs (handwritten notes, printed reports, legal docs) to LaTeX. Full pipeline: references/pdf-conversion.md.

Quick steps: Split PDF into page images (scripts/pdf_to_images.sh), select a conversion profile, create shared preamble, apply scaling strategy, validate with scripts/validate_latex.py, concatenate, compile.

Scaling strategy: 1-10 pages = single agent; 11-20 pages = split in half (2 agents); 21+ pages = batch-7 pipeline (ceil(N/7) agents with run_in_background: true).

Conversion profiles (in references/profiles/): math-notes.md (equations, theorems -- has beautiful mode), business-document.md (reports, memos), legal-document.md (contracts, statutes), general-notes.md (handwritten, mixed content).

Workflow: Fill PDF Forms

Fill existing PDF forms -- both fillable (with form fields) and non-fillable (image-based). Full guide: references/pdf-operations.md.

Step 1: Check form type:

python3 <skill_path>/scripts/pdf_check_form.py form.pdf

If fillable (has form fields):

# Extract field metadata
python3 <skill_path>/scripts/pdf_extract_fields.py form.pdf field_info.json
# Create field_values.json with values for each field, then fill
python3 <skill_path>/scripts/pdf_fill_form.py form.pdf field_values.json output.pdf

If non-fillable (no form fields):

# Convert to images for visual analysis
bash <skill_path>/scripts/pdf_to_images.sh form.pdf ./tmp/pages
# Visually identify fields, create fields.json with bounding boxes
# Validate bounding boxes (+ optional validation image)
python3 <skill_path>/scripts/pdf_validate_boxes.py fields.json --image page_1.png --output validation.png --page 1
# Fill with text annotations
python3 <skill_path>/scripts/pdf_fill_annotations.py form.pdf fields.json output.pdf

Workflow: Advanced PDF Operations

For text/table extraction (pdfplumber), OCR (pytesseract), programmatic PDF creation (reportlab), watermarking, page rotation/cropping, metadata extraction, JavaScript libraries (pdf-lib, pdfjs-dist), and batch processing, see references/pdf-operations.md.

Compile Script

# Basic compile (auto-detects engine)
bash <skill_path>/scripts/compile_latex.sh document.tex

# Compile + generate PNG previews
bash <skill_path>/scripts/compile_latex.sh document.tex --preview

# Compile + PNG in specific directory
bash <skill_path>/scripts/compile_latex.sh document.tex --preview --preview-dir ./outputs

# Force a specific engine
bash <skill_path>/scripts/compile_latex.sh document.tex --engine xelatex
bash <skill_path>/scripts/compile_latex.sh document.tex --engine lualatex

# Use latexmk for automatic multi-pass (recommended for complex documents)
bash <skill_path>/scripts/compile_latex.sh document.tex --use-latexmk --preview

# PDF/A output for thesis submissions and archival compliance
bash <skill_path>/scripts/compile_latex.sh document.tex --pdfa

# Verbose output for debugging compilation issues
bash <skill_path>/scripts/compile_latex.sh document.tex --verbose

# Quiet mode for batch/CI jobs (only errors shown)
bash <skill_path>/scripts/compile_latex.sh document.tex --quiet

# Clean auxiliary files only (no compilation)
bash <skill_path>/scripts/compile_latex.sh document.tex --clean

Compilation Flags

Compilation Backends

Manual multi-pass (default): Runs the engine multiple times with bibliography/index/glossary passes as needed. This is the traditional approach and works without latexmk installed.

latexmk (--use-latexmk): Uses latexmk for automatic dependency-driven compilation. Recommended for complex documents with bibliographies, indexes, glossaries, or cross-references -- latexmk determines the correct number of passes automatically. Requires latexmk (included with TeX Live).

Log Filtering (texfot)

When texfot is installed (included with TeX Live), compilation output is automatically filtered to show only relevant warnings and errors, suppressing noisy package loading messages. This applies in the default verbosity mode. Use --verbose to see unfiltered output, or --quiet to suppress all non-error output.

Engine auto-detection: If the .tex file uses fontspec, xeCJK, or polyglossia, the script automatically uses xelatex. If it uses luacode or luatextra, it uses lualatex. Otherwise defaults to pdflatex. Override with --engine.

The script auto-installs texlive (including texlive-science, texlive-xetex, texlive-luatex, biber) and poppler-utils if missing. It auto-detects ibliography{} (runs bibtex), ddbibresource{} (runs biber), \makeindex (runs makeindex), \makeglossaries (runs makeglossaries), runs the correct number of passes, generates PNG previews with pdftoppm, and cleans auxiliary files.

Script & Tool Reference

For PDF utilities (encrypt, merge, optimize, extract pages, pdf-to-images), LaTeX quality tools (lint, word count, analysis, package check, citations), compilation auto-fix, bibliography fetching, and diagram scripts (Mermaid, Graphviz, PlantUML), see references/script-tools.md.

Templates

Copy from assets/templates/ and customize.

Resume Templates (5 ATS-Compatible Options)
