# LaTeX PDF Compiler

This skill enables Claude to create Overleaf-compatible LaTeX documents and compile them to PDF using the user's local pdflatex installation.

## When to Use This Skill

Activate this skill when the user:
- Asks to "create a LaTeX [document] and compile it"
- Requests "make a PDF using LaTeX"
- Says "compile this LaTeX" or "compile to PDF"
- Asks to "generate and compile" any LaTeX document
- Requests updates to existing LaTeX with recompilation

## Workflow

### Single-Step Generation and Compilation

When user requests a LaTeX document with compilation:

1. **Generate Overleaf-Compatible LaTeX**
   - Create clean, well-structured LaTeX using standard document classes
   - Use common, widely-available packages
   - Put LaTeX source in a code artifact with `language="latex"`

2. **Compile Immediately**
   - Use the `compile_latex.py` script to compile the LaTeX
   - Run pdflatex twice (for references and TOC)
   - Provide the compiled PDF to the user

3. **Present Both Artifacts**
   - Show the LaTeX source code artifact (editable)
   - Provide the compiled PDF

### Update and Recompile

When user requests changes to existing LaTeX:

1. **Update the LaTeX artifact** with requested changes
2. **Recompile automatically** using the compilation script
3. **Update the PDF** artifact or provide new download

### Compile-Only

When user says "compile this" with existing LaTeX artifact:

1. **Extract LaTeX from the artifact**
2. **Compile using the script**
3. **Provide the PDF**

## LaTeX Generation Guidelines

### Standard Practices
- Use standard document classes: `article`, `report`, `book`, `letter`
- Include only common packages that work in Overleaf:
  - `amsmath`, `amssymb` - Math symbols
  - `graphicx` - Images
  - `hyperref` - Hyperlinks
  - `geometry` - Page layout
  - `fancyhdr` - Headers/footers
  - `enumitem` - List formatting
  - `xcolor` - Colors
- Use UTF-8 encoding
- Ensure proper document structure

### Example LaTeX Structure

```latex
\documentclass[11pt,a4paper]{article}

\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{hyperref}
\usepackage[margin=1in]{geometry}

\title{Document Title}
\author{Author Name}
\date{\today}

\begin{document}

\maketitle

\section{Introduction}
Content here...

\end{document}
```

## Compilation Process

The skill uses the `compile_latex.py` script which:

1. **Writes LaTeX to temporary .tex file**
2. **Runs pdflatex twice** with flags:
   - `-interaction=nonstopmode` (don't stop on errors)
   - `-output-directory` (specified temp directory)
3. **Captures output and errors**
4. **Returns**:
   - Success: PDF file path and base64-encoded PDF data
   - Failure: Error messages and log excerpts

## Error Handling

If compilation fails:
- Show relevant error messages from the LaTeX log
- Suggest common fixes (missing packages, syntax errors, etc.)
- Offer to update the LaTeX and retry

## Output Format

After successful compilation:
- Provide download link or base64-encoded PDF
- Keep the LaTeX source artifact for future edits
- Mention file location if saved locally

## Requirements

- `pdflatex` must be installed (TeX Live, MiKTeX, or MacTeX)
- `pdflatex` should be in system PATH
- Python 3.x available for the compilation script

## Common Use Cases

1. **Academic Papers**: `\documentclass{article}` with `amsmath`, sections, bibliography
2. **Resumes/CVs**: Clean formatting with `geometry`, `enumitem`
3. **Reports**: `\documentclass{report}` with chapters, TOC, figures
4. **Letters**: `\documentclass{letter}` with proper formatting
5. **Math Homework**: Heavy use of `amsmath`, `align`, equation environments
6. **Presentations**: `\documentclass{beamer}` for slides

## Script Location

The compilation script should be located at:
`scripts/compile_latex.py`

This script is automatically invoked when compilation is needed.
