Paper Poster: From Paper to Conference Poster

Generate a conference poster from: **$ARGUMENTS**

Context

This skill runs **after** Workflow 3 (`/aris-paper-writing`). It takes a compiled paper and generates a print-ready poster for conference poster sessions. The poster extracts key content from the paper — it does **not** dump the full paper text onto a poster.

Unlike papers (dense prose, 8-15 pages), posters are **visual-first**: one page, 4 columns, bullet points only, figures dominant. A good poster tells the story in 60 seconds.

Constants

• **VENUE = `NeurIPS`** — Target venue, determines color scheme. Supported: `NeurIPS`, `ICML`, `ICLR`, `AAAI`, `ACL`, `EMNLP`, `CVPR`, `ECCV`, `GENERIC`. Override via argument (e.g., `/aris-paper-poster "— venue: ICML"`).
• **POSTER_SIZE = `A0`** — Paper size. Options: `A0` (841x1189mm, default), `A1` (594x841mm).
• **ORIENTATION = `landscape`** — Orientation. Options: `landscape` (default), `portrait`.
• **COLUMNS = 4** — Number of content columns. Typical: 4 for landscape A0 (IMRAD), **3 for portrait A0** (research consensus), 2 for portrait A1. Portrait A0 should NEVER use 4 columns — text becomes too narrow and unreadable.
• **PAPER_DIR = `paper/`** — Directory containing the compiled paper (main.tex + figures/).
• **OUTPUT_DIR = `poster/`** — Output directory for all poster files.
• **REVIEWER_MODEL = `gpt-5.4`** — Model used via Codex MCP for poster review.
• **AUTO_PROCEED = false** — At each checkpoint, **always wait for explicit user confirmation**. Set `true` only if user explicitly requests fully autonomous mode.
• **COMPILER = `latexmk`** — LaTeX build tool.
• **ENGINE = `pdflatex`** — LaTeX engine. Use `xelatex` for CJK text.

Venue Color Schemes

Use **deep, saturated** colors for primary — pastel/light colors wash out on large posters viewed from distance. Each venue uses a **3-color system**: primary (dark, for title bar), secondary (medium, for section headers), accent (contrast, for highlights).

| Venue | Primary | Secondary | Accent | Background | Text | |-------|---------|-----------|--------|------------|------| | NeurIPS | `#4C1D95` (deep purple) | `#6D28D9` (purple) | `#2563EB` (blue) | `#F5F3FF` | `#1F2937` | | ICML | `#7F1D1D` (deep maroon) | `#B91C1C` (red) | `#1E40AF` (blue) | `#EDD5D5` | `#111827` | | ICLR | `#065F46` (deep green) | `#059669` (green) | `#0284C7` (blue) | `#F0FDF4` | `#1F2937` | | CVPR | `#1E3A8A` (deep blue) | `#2563EB` (blue) | `#7C3AED` (purple) | `#F8FAFC` | `#1F2937` | | AAAI | `#0C4A6E` (deep navy) | `#0369A1` (blue) | `#DC2626` (red) | `#F0F9FF` | `#1F2937` | | ACL | `#155E75` (deep teal) | `#0891B2` (teal) | `#7C3AED` (purple) | `#F0FDFA` | `#1F2937` | | EMNLP | `#713F12` (deep amber) | `#D97706` (amber) | `#2563EB` (blue) | `#FFFBEB` | `#1F2937` | | ECCV | `#701A75` (deep fuchsia) | `#C026D3` (fuchsia) | `#0891B2` (teal) | `#FDF4FF` | `#1F2937` | | GENERIC | `#1E293B` (deep slate) | `#334155` (slate) | `#2563EB` (blue) | `#F8FAFC` | `#1F2937` |

> ⚠️ **Color lesson**: Never use light/pastel colors (e.g., `#8B5CF6`) as primary — they look washed out on A0 posters. Always use the darkest shade as primary for the title bar.

State Persistence (Compact Recovery)

Poster generation can be long. Persist state to `poster/POSTER_STATE.json` after each phase:

{
  "phase": 3,
  "venue": "NeurIPS",
  "poster_size": "A0",
  "orientation": "landscape",
  "columns": 4,
  "figures_selected": ["architecture.pdf", "results.pdf"],
  "codex_thread_id": "019cfcf4-...",
  "status": "in_progress",
  "timestamp": "2026-03-18T15:00:00"
}

**On startup**: if `POSTER_STATE.json` exists with `"status": "in_progress"` and within 24h → resume from saved phase. Otherwise → fresh start.

Critical LaTeX Architecture Decisions

> ⚠️ **MUST use `article` class, NEVER `beamer` class.** The beamer class consumes too many TeX grouping levels for its overlay/mode system. Combined with tcbposter's `enhanced` style on 8+ posterboxes, this triggers `! TeX capacity exceeded, sorry [grouping levels=255]`. The article class + geometry package for custom page size is the correct approach. This was validated through 5 failed compilation attempts with beamer before switching to article.

> ⚠️ **NEVER use `adjustbox` package.** It may not be installed in minimal TeX distributions. Use plain `\includegraphics[width=0.96\linewidth]{file}` instead. Do NOT use `max height` option (requires adjustbox).

Template Foundation

\documentclass{article}
% A0 landscape: paperwidth=1189mm,paperheight=841mm
% A0 portrait:  paperwidth=841mm,paperheight=1189mm
\usepackage[paperwidth=1189mm,paperheight=841mm,margin=0mm]{geometry}
\usepackage{tcolorbox}
\tcbuselibrary{poster,skins,fitting}
\usepackage{graphicx}
\usepackage{amsmath,amssymb}
\usepackage{enumitem}
\usepackage[table]{xcolor}  % MUST use [table] option for \rowcolor in tables
\usepackage{lmodern}
\usepackage[T1]{fontenc}
\pagestyle{empty}

> ⚠️ **NEVER use `\usepackage[most]{tcolorbox}`** — it pulls in `listingsutf8.sty` which may not be installed. Always use `\tcbuselibrary{poster,skins,fitting}` explicitly.

> ⚠️ **Use `[table]{xcolor}`** not plain `{xcolor}` — needed for `\rowcolor` in benchmark tables. The `colortbl` package is loaded automatically by this option.
