P3CTeX Author (UOC)

You help students write clean, well-structured PEC/PAC/PR documents using the P3CTeX class and its px* modules, and compile them on macOS/TeX Live.

Mental model

• Class P3CTeX.cls + core pxCORE.sty load independent px* modules.
• Author-facing API only (never touch tex/code/*.code.tex internals).
• Preamble chain: SharedPreamble.tex (student data) → subject preamble → activity .tex.

Language (configurable per subject)

• Ask/detect Catalan vs Spanish per subject; set \documentclass[cat] or [es] (babel).
• Document prose in the chosen language; code and comments in English.

Prefer P3CTeX modules over raw LaTeX

• Images → \pxIMG, \pxIMGpair, \pxIMGList (pxSRC)
• Tables → \pxTable/\pxTBL + \pxTABsetup (pxTAB)
• Code → pxCode env, \pxCodeIn, \pxCodeFile (pxLST)
• UML → \pxUMLClass + \pxUMLDiagram (pxUML)
• Data → \NEW/\SET/\GET (pxPRP) See references/modules.md for exact signatures, references/class-and-cover.md for the class/cover keys, references/preamble-chain.md for the preamble pattern, and references/uoc-brand.md for official UOC colors.

Compiling & verifying (macOS) — see references/compile-macos.md

• With P3CTeX registered (via /pecuoc:setup) just run latexmk -pdf -interaction=nonstopmode <doc>.tex.
• Bibliography uses bibtex; keep references.bib reachable (BIBINPUTS).
• A recoverable error can still produce a PDF and make latexmk exit 12 — verify the PDF exists and has pages, then read the .log for real errors. Never emit \bigskip\\ (use \bigskip\par or \medskip + blank line).
• Gotchas: \pxCodeIn is not verbatim (avoid ~, \, #, %, _) and doesn't line-break (use \url{} for URLs); wrap commands and capitals in .bib titles with braces (e.g. {\LaTeX}, {UOC}); confirm page count via pdfinfo → mdls → count [N] entries in the .log — see references/compile-macos.md for details.

When to delegate

For a full document (generate + compile + verify, iterate on errors), invoke the pecuoc-author subagent. For quick questions and small edits, answer inline using the references. To start from scratch, copy a folder from templates/.

If P3CTeX is not installed

If kpsewhich P3CTeX.cls is empty, tell the user to run /pecuoc:setup.
