name: latex-scaffold description: | Scaffold a LaTeX project (latex/main.tex, bibliography wiring, structure) from an existing Markdown draft and citations/ref.bib. Trigger: latex scaffold, md→tex, LaTeX 项目骨架, 生成 main.tex. Use when: 需要 LaTeX/PDF 交付（例如 arxiv-survey-latex pipeline），且 draft 已生成/已进入写作阶段。 Skip if: 还没有 output/DRAFT.md（或你不需要 LaTeX 交付）。 Network: none. Guardrail: 移除 markdown 残留（##, **, [@...]）；bibliography 指向 citations/ref.bib；不在此步骤改写内容。

LaTeX Scaffold

Convert the approved Markdown draft into a minimal, buildable LaTeX project.

This is a deterministic conversion step; prose quality should already be addressed in output/DRAFT.md.

Inputs

• output/DRAFT.md (or another approved draft)
• citations/ref.bib

Outputs

• latex/main.tex (and any required LaTeX support files)

Workflow

1. Create latex/ directory if missing.
2. Create latex/main.tex with sections matching the outline.
3. Wire bibliography to citations/ref.bib.

Quality checklist

• latex/main.tex exists and references citations/ref.bib.

Script

Quick Start

• python .codex/skills/latex-scaffold/scripts/run.py --help
• python .codex/skills/latex-scaffold/scripts/run.py --workspace <workspace_dir>

All Options

• See --help (inputs/outputs are taken from the unit runner when used via pipeline)

Examples

• Build latex/main.tex from output/DRAFT.md:
  • python .codex/skills/latex-scaffold/scripts/run.py --workspace <ws>

Notes

• The generated latex/main.tex includes a table of contents (tocdepth=2) for readability.
• Language default: the scaffold uses article (English-looking front matter). If the draft contains CJK characters, it switches to ctexart so the PDF renders correctly.
• Conversion rules (high level):
  • Headings ##/###/#### → \section/\subsection/\subsubsection (strips leading numeric prefixes like 1.2).
  • ## Abstract → abstract environment.
  • [@Key] or [@Key1; @Key2] → \citep{Key} / \citep{Key1,Key2}.
  • Inline markdown **bold** / *italic* / `code` → \textbf{} / \emph{} / \texttt{}.

Troubleshooting

Issue: the generated latex/main.tex still contains Markdown markers

Fix:

• Re-run latex-scaffold and ensure the input output/DRAFT.md is clean (no ##, no **, no [@...] syntax that isn""t handled).

Issue: citations are missing in LaTeX

Fix:

• Ensure citations/ref.bib exists and the scaffold points bibliography to it; then compile with latex-compile-qa.
