Section Writing Agent (Step 4)

Faithful implementation of the Section Writing Agent from PaperOrchestra (Song et al., 2026, arXiv:2604.05018, §4 Step 4, App. F.1 pp. 47–49).

Cost: ONE LLM call (App. B: "Section Writing Agent (1 call): A single, comprehensive multimodal call to draft and compile the complete LaTeX manuscript"). Do NOT split this into per-section calls — the paper explicitly designs it as one comprehensive call so the model can maintain global coherence across sections.

Inputs

• workspace/outline.json — the master plan
• workspace/inputs/idea.md — technical details
• workspace/inputs/experimental_log.md — raw data for tables and qualitative analysis
• workspace/drafts/intro_relwork.tex — the template with Intro + Related Work already filled in by Step 3. This is your starting point. The preamble, package list, style, and the two pre-filled sections must be preserved verbatim.
• workspace/citation_pool.json — the citation map ({key, title, abstract} for each verified paper)
• workspace/refs.bib — the BibTeX file
• workspace/inputs/conference_guidelines.md — formatting rules
• workspace/figures/ — the actual PNG files from Step 2 (used as multimodal vision input!)
• workspace/figures/captions.json — caption text per figure_id
• workspace/tex_profile.json — TeX package availability flags (written by check_tex_packages.py at Step 0). Read this before generating any LaTeX. It tells you which packages are installed so you select the right cross-reference pattern, font packages, etc. before you write — not after you try to compile.

Output

• workspace/drafts/paper.tex — the complete LaTeX paper, with all sections filled. The Step 5 Refinement Agent will iterate on this file.

How to do it

0.5. Read tex_profile.json and select LaTeX patterns

Before composing the prompt, read workspace/tex_profile.json and apply these rules to every LaTeX choice in the generated paper:

Profile flag	True → use	False → use instead
use_cleveref	\cref{fig:X}, \cref{tab:Y}	Figure~\ref{fig:X}, Table~\ref{tab:Y}
use_nicefrac	\nicefrac{a}{b}	$a/b$
use_microtype	\usepackage{microtype}	omit the line
use_t1_fontenc	\usepackage[T1]{fontenc}	omit the line
