Paper Poster: From Paper to Conference Poster

Generate a conference poster from: $ARGUMENTS

Context

This skill runs after Workflow 3 (/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., /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-5.5 — 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.

💡 Override: /paper-poster "paper/" — venue: CVPR, size: A1, orientation: portrait, columns: 3

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.

tcbposter Layout Rules (Critical)

⚠️ The #1 cause of poster failures is content overflow. tcbposter uses a fixed grid — content that exceeds the box is silently clipped with no compilation error. You will NOT see any warning; the poster will simply be cut off.

⚠️ The #2 cause is large whitespace gaps. Using too few rows (e.g., rows=5) creates ~168mm per row on A0 landscape. If title text only needs 120mm, the remaining 48mm is wasted whitespace. Solution: use rows=20 for fine-grained control (~42mm per row).

Grid System: `rows=20` (Critical)

Use rows=20 for A0 landscape. Each row ≈ 42mm, giving precise control over section heights.

Recommended row allocation for 4-column A0 landscape:

Section	Rows	Height	Row range
Title bar	3	~126mm	`top` to `row4`
Stat banner	2	~84mm	`row4` to `row6`
Body content	14	~588mm	`row6` to `bottom`

Key principle: Always use between=rowN and rowM syntax (not below=name) for precise vertical placement. The below= syntax lets tcolorbox auto-place, which often leaves unwanted gaps.

Row Count Guidance

Poster Size	Orientation	Recommended rows	Columns	Row height
A0	landscape	20	4	~42mm
A0	portrait	20	3	~59mm
A1	landscape	16	3	~37mm
A1	portrait	20	2	~30mm

Portrait A0 Layout (3 columns, rows=20)

⚠️ Portrait A0 posters use 2-3 columns, NEVER 4. Research consensus: "Two columns is typical for a poster with a portrait orientation" (Colin Purrington, NYU poster guides). At 841mm width, 4 columns give only ~195mm per column — too narrow for readable text at poster-session distance. 3 columns (~260mm each) is the recommended default for content-rich papers. Use 2 columns for simpler posters or when figures need more horizontal space.

For portrait posters (841x1189mm), use a 3-column, 3-row-band layout:

Section	Rows	Row range	Content
Title bar	4	`top` to `row4`	Title + authors + venue (span=3)
Stat banner	2	`row4` to `row6`	3 headline stat callouts (span=3)
Row A	5	`row6` to `row11`	Background+Motivation, Method (hero fig), Key Results (fig)
Row B	5	`row11` to `row16`	Contributions, Equations+Ablation, Result 2 (fig+table)
Row C	4	`row16` to `bottom`	References+QR, Setup+Benchmarks, Key Takeaways

3-column portrait layout diagram:

┌─────────────────────────────────────┐
│         TITLE BAR (span=3)          │
├─────────────────────────────────────┤
│   Stat 1   │   Stat 2   │  Stat 3  │

├────────────┼────────────┼──────────┤
│ References │  Setup &   │   Key    │
│ + QR Code  │ Benchmarks │Takeaways │
└────────────┴────────────┴──────────┘

⚠️ All 3 columns in each row band share the same row boundaries. This ensures cross-column alignment. Never mix row6 to row11 in one column with row6 to row10 in another — it creates visual misalignment.

⚠️ Use spacing=0mm for tight layouts. Card separation is handled by card styles (left accent stripe, drop shadow), not grid spacing. Grid spacing > 2mm creates visible gaps between rows.

Modern Card Design System (Left Accent Stripe)

Instead of rounded boxes with colored headers, use a left accent stripe design. This is cleaner, more modern, and avoids the "PowerPoint box" look.

Define 4 card styles using the venue's 3-color system:

% Tinted card backgrounds (NOT pure white — adds warmth)
\definecolor{redbg}{HTML}{FFF5F3}     % warm pink tint for redcard
\definecolor{bluebg}{HTML}{F0F4FF}    % cool blue tint for bluecard
\definecolor{darkbg}{HTML}{FDF6F3}    % warm cream tint for darkcard
\definecolor{redtitlebg}{HTML}{FDEAE8}   % title bar tint
\definecolor{bluetitlebg}{HTML}{E4ECFF}
\definecolor{darktitlebg}{HTML}{F5E8E2}

\tcbset{
  redcard/.style={
    enhanced, arc=0pt, boxrule=0pt, colback=redbg,
    borderline west={5pt}{0pt}{secondary},
    left=16pt, right=14pt, top=4pt, bottom=4pt,
    fonttitle=\fontsize{40}{48}\selectfont\bfseries\color{secondary},
    coltitle=secondary, colbacktitle=redtitlebg,
    toptitle=6pt, bottomtitle=6pt,
    titlerule=2pt, titlerule style={secondary!50},
    valign=top, drop shadow={opacity=0.18},
  },
  bluecard/.style={...same pattern with accent color and bluebg...},
  darkcard/.style={...same pattern with primary color and darkbg...},
  highlightcard/.style={
    enhanced, arc=0pt, boxrule=0pt, colback=primary!18!white,
    borderline west={6pt}{0pt}{primary},
    fonttitle=...\color{white}, colbacktitle=primary,
    ...
  },
}

Card assignment pattern (creates visual rhythm):

redcard (secondary stripe): Background, Key Idea, Ablation, References, Setup
bluecard (accent stripe): Result 1, Result 2, Benchmarks, Analysis
darkcard (primary stripe): Contributions, Method
highlightcard (primary fill): Key Takeaways / Conclusion

⚠️ Card backgrounds must NOT be pure white (#FFFFFF). Use subtle tints matching the card's color family. Pure white cards on a tinted poster background look disconnected. The tint should be barely visible but adds cohesion.

Figure + Caption Macro

Define a consistent macro for all figures to ensure uniform spacing:

\newcommand{\posterfig}[3]{%
  \centering\includegraphics[width=#1\linewidth]{#2}\\[3mm]
  {\fontsize{26}{32}\selectfont\color{textgray}\textit{#3}}\vspace{2mm}%
}
% Usage: \posterfig{0.96}{figures/results.png}{Caption text here.}

⚠️ Inconsistent figure-text spacing is the #1 visual flaw in generated posters. The \posterfig macro enforces uniform 3mm gap + 2mm bottom padding across all figures.

Content Colorbox Intensity

Inside cards, use \colorbox{color!N} for highlighted blocks. The intensity N must be 18-25% (not 8-12% which is too faint):

% TOO FAINT (invisible on print):
\colorbox{primary!8}{\parbox{...}{...}}

% CORRECT (visible, distinct):
\colorbox{primary!20}{\parbox{0.94\linewidth}{...}}
\colorbox{accent!20}{\parbox{0.94\linewidth}{...}}
\colorbox{secondary!20}{\parbox{0.94\linewidth}{...}}

Similarly, \rowcolor in tables should use 15% intensity: \rowcolor{primary!15}.

Font Size Rules (A0 at article class — NO scale factor)

⚠️ Critical: When using article class (not beamerposter), there is NO automatic scale factor. All font sizes are literal. A poster viewed from 1.5m needs much larger fonts than you think.

Element	Font size	Leading	Example
Title	90pt	108pt	`\fontsize{90}{108}\selectfont`
Author line	42pt	50pt	`\fontsize{42}{50}\selectfont`
Section headers	42pt	50pt	via `fonttitle=\fontsize{42}{50}...`
Sub-headers	38pt	46pt	`\subheader{}{}` command
Body text	34pt	44pt	`\fontsize{34}{44}\selectfont`
Stat callout numbers	72pt	86pt	`\fontsize{72}{86}\selectfont`
Stat callout labels	30pt	36pt	`\fontsize{30}{36}\selectfont`
Equations	32pt	40pt	`\fontsize{32}{40}\selectfont`
Table cells	30pt	38pt	`\fontsize{30}{38}\selectfont`
Figure captions	28pt	34pt	`\fontsize{28}{34}\selectfont`
References	30pt	40pt	`\fontsize{30}{40}\selectfont`

⚠️ Lesson learned from testing: Body text at 20pt on A0 is unreadable from more than 0.5m. 34pt is the minimum for comfortable reading at poster-session distance.

Content Budget

Total target: 300-500 words (excluding figure captions and stat callout numbers).

⚠️ The #1 content mistake is too much text. A poster is NOT a paper summary — it's a visual guide. Each bullet should be a key phrase (5-8 words), not a sentence. If you find yourself writing full sentences, you're putting too much text.

⚠️ Content density calibration: When in doubt, use LESS text. It's much easier to add a few words than to trim dense paragraphs. Target ~70% fill per card (some breathing room), NOT 100%.

Box type	Max bullets	Max words	Figure?	Style
Background	3	40-60	No	Short bullets + 1 key insight colorbox
Key Idea / Architecture	0-1	20-30	Yes (hero fig)	Figure dominant + 2 one-liner colorboxes
Contributions	3-4	60-80	No	Numbered, 1 line each
Method	2-3	40-60	No	2 equation colorboxes + 3 short bullets
Results (each)	2-3	30-50	Yes (figure)	Figure + 2-3 one-line colorboxes
Ablation	3	30-40	No	3 colorboxes, 2 lines each max
Analysis	3	30-50	Yes (figure)	Figure + 3 one-line colorboxes
References	4-5	30-40	No	Author (year). Short title. Venue
Setup	4-5	30-40	No	5 one-liner colorboxes
Benchmarks	0	20	No	Table + 1-line caption
Key Takeaways	3	30-40	No	3 short items + code link

Bullet point rules:

Maximum 8 words per bullet when possible
Use $\Rightarrow$ and $\to$ for causal arrows instead of words
Numbers > words: "42% less memory" not "reduces memory usage by 42 percent"
Colorbox labels: "vs. Depth: 4L CoE ≈ 12L MoE, 42% less memory" (one line)

Workflow

Phase 0: Input Validation & Setup

Check prerequisites:

which pdflatex && which latexmk

If LaTeX is NOT installed, try in order:

# Option 1: brew cask (requires sudo — may fail in non-interactive shells)
brew install --cask mactex-no-gui

# Option 2: BasicTeX (smaller, may still need sudo)
brew install --cask basictex

# Option 3: User-directory install (NO sudo needed — always works)

tlpdbopt_install_srcfiles 0
PROF
./install-tl --profile=texlive.profile
export PATH="$HOME/texlive/YYYY/bin/universal-darwin:$PATH"

After installation, install required packages:

tlmgr install tcolorbox pgf etoolbox environ trimspaces \
  type1cm pdfcol tikzfill latexmk lm enumitem geometry

⚠️ Lesson learned: brew install --cask mactex-no-gui often fails in non-interactive shells because the macOS installer requires sudo password. The user-directory TeX Live install (Option 3) always works without sudo.

⚠️ Do NOT install or use beamerposter. The article class approach does not need it.

Verify paper exists:

ls $PAPER_DIR/main.tex || ls $PAPER_DIR/main.pdf
ls $PAPER_DIR/sections/*.tex
ls $PAPER_DIR/figures/

Backup existing poster: if poster/ exists, copy to poster-backup-{timestamp}/
Create output directory: mkdir -p poster/figures

Copy figures to poster directory:

# IMPORTANT: Use cp, NOT ln -sf (symlinks)
# pdflatex often fails to resolve symlinks across directories
cp paper/figures/selected_figure.pdf poster/figures/

⚠️ Never use symlinks for poster figures. pdflatex cannot reliably follow symlinks across directories. Always cp the actual files.

Convert PDF figures to PNG for PPTX embedding:

python3 -c "import pdf2image" 2>/dev/null || pip install pdf2image
# For each figure:
python3 -c "
from pdf2image import convert_from_path
for name in ['paradigm', 'architecture', 'results', 'hallucination']:
    imgs = convert_from_path(f'poster/figures/{name}.pdf', dpi=300)
    imgs[0].save(f'poster/figures/{name}.png', 'PNG')
"

⚠️ python-pptx CANNOT embed PDF images. You MUST convert to PNG first. This is a hard limitation of the OOXML format. Always generate PNG copies at 300 DPI during setup.

Detect CJK: if paper contains Chinese/Japanese/Korean text, set ENGINE to xelatex
Check for resume: read poster/POSTER_STATE.json if it exists

Phase 1: Content Extraction

Read each section from paper/sections/*.tex and extract poster-appropriate content:

Extraction rules — a poster shows ~30-40% of the paper's content:

Paper Section	Poster Extraction	Target Length
Abstract	Skip — replace with 2-4 big-number stat callout boxes spanning all columns	0 words (numbers only)
Introduction	Motivation: 2-3 bullet points + numbered contribution list (4 items)	120-160 words
Method	1 hero architecture figure + key equations + 3-5 bullet points	80-120 words
Experiments	Dataset details + main result figures + numeric stat tables + ablation	150-200 words
Conclusion	3-4 key findings + 2-3 next steps	60-80 words
Related Work	Skip entirely — no space on poster	0

Total target: 400-700 words (excluding figure captions and stat callout numbers).

⚠️ No abstract paragraph on poster. Replace with a stat banner: 3-4 large-number callout boxes showing headline results. This is the single highest-impact change for 60-second comprehension.

Output: poster/POSTER_CONTENT_PLAN.md — structured markdown showing exactly what goes where, with word counts per box.

🚦 Checkpoint:

📋 Poster content plan ready:
- Title: [paper title]
- Venue: [VENUE] ([POSTER_SIZE] [ORIENTATION])
- Layout: [COLUMNS] columns, rows=20
- Figures selected: [N] figures
- Boxes per column: Col1=[N], Col2=[N], Col3=[N], Col4=[N]
- Estimated word count: [N] words

Proceed with this layout? Or adjust content selection?

⛔ STOP HERE and wait for user response.

State: Write POSTER_STATE.json with phase: 1.

Phase 2: Figure Selection & Layout

Inventory all figures in paper/figures/:

ls -la paper/figures/*.{pdf,png,jpg,svg} 2>/dev/null

Rank by poster importance:
- Tier 1 (must include): Architecture/method overview diagram, main results plot
- Tier 2 (include if space): Ablation bar chart, qualitative examples, experimental paradigm
- Tier 3 (skip): Appendix figures, supplementary plots, tables-as-figures
Select top 3-5 figures that fit the 4-column layout
Copy figures to poster directory (NOT symlinks) + convert PDF→PNG for PPTX
Design column layout — 4-column IMRAD:
- Col 1: Background & Motivation + Contributions + References & QR
- Col 2: Dataset & Paradigms (fig) + Computational Models (equations)
- Col 3: Architecture (fig) + Result 1 (fig + stat table)
- Col 4: Result 2 (fig + stat table) + Ablation + Conclusion

Phase 3: Generate Poster LaTeX

Create poster/main.tex using article class + geometry + tcbposter.

Key formatting rules:

Title: 84pt, bold, primary background, white text
Author line: 36pt, white text
Section headers: 40pt via fonttitle — colored text on tinted title background
Body text: 34pt with 44pt leading — \fontsize{34}{44}\selectfont
Figures: via \posterfig{0.96}{figures/name.png}{Caption} macro
Stat callout numbers: 66pt in primary color on stathighlight background
Tables: \renewcommand{\arraystretch}{1.6} with \rowcolor{primary!15} zebra striping
Equations in colorboxes: use $\displaystyle ...$ (inline), NOT \[...\] (display math adds margins that cause overfull hbox)

Posterbox pattern (using card styles):

\posterbox[redcard, title={Section Title}
]{name=uniquename, column=N, between=rowA and rowB}{
  \fontsize{34}{44}\selectfont
  \begin{itemize}[itemsep=12pt]
    \item Key point one
    \item Key point two
  \end{itemize}
}

⚠️ Equations in narrow colorboxes: Display math \[...\] adds horizontal margins that cause overfull hbox errors inside \colorbox{\parbox{}}. Always use $\displaystyle ...$ with \centering instead. Reduce equation font to 26-28pt inside colorboxes.

🚦 Checkpoint:

🖼️ Poster LaTeX generated:
- Template: article + tcbposter (rows=20)
- Layout: [COLUMNS] columns, [ORIENTATION] [POSTER_SIZE]
- Colors: [VENUE] theme (primary: [HEX] / secondary: [HEX] / accent: [HEX])
- Figures: [N] embedded
- Font sizes: title=90pt, body=34pt, headers=42pt
- Word count: ~[N] words

Compile now?

⛔ STOP HERE and wait for user response.

State: Write POSTER_STATE.json with phase: 3.

Phase 4: Compile Poster

cd poster && latexmk -pdf -interaction=nonstopmode main.tex

⚠️ If using user-directory TeX Live, prepend PATH: export PATH="$HOME/texlive/YYYY/bin/universal-darwin:$PATH"

Error handling loop (max 3 attempts):

Parse error log for the first error
Fix the most likely cause:
- grouping levels=255 → STOP. Switch from beamer to article class. This is not fixable by removing styles.
- Missing package → tlmgr install <package>
- File not found: adjustbox.sty → Remove \usepackage{adjustbox} and any max height options
- File not found → verify poster/figures/ has the file (not a broken symlink)
- Overfull boxes → reduce text or figure size
Recompile

Common missing packages (install proactively if not present):

tlmgr install type1cm pdfcol tikzfill

Verification:

pdfinfo poster/main.pdf
# Check: Pages: 1, Page size: ~3370.39 x 2383.94 pts (A0 landscape)

Visual inspection after compilation:

All 4 columns have content visible to the bottom — no silent clipping
No large whitespace gaps between title/stats and body content
Figures are fully visible, not cut off
Text is readable (zoom to 100% = actual A0 size)

Phase 5: Visual Review via Claude + Gemini (Iterative Refinement)

This phase uses Claude visual assessment on rendered poster images to iteratively refine layout, readability, and visual hierarchy — similar to the paper-illustration skill's review loop.

Step 1: Render poster to PNG preview

import fitz
doc = fitz.open('poster/main.pdf')
page = doc[0]
pix = page.get_pixmap(dpi=200)  # 200 DPI for visual review (higher than 150 preview)
pix.save('poster/poster_review.png')
doc.close()

Step 2: Claude visual assessment

Read the rendered poster/poster_review.png and perform a STRICT visual review with the following rubric (score 1-10):

Critical checks (must all pass, any failure = score ≤ 5):

Content accuracy — No fabricated data, all numbers match paper
Text readability — All text readable at simulated 1.5m distance (no text too small)
No clipping — All content visible, no cut-off figures or text
Column alignment — Row bands align across all columns

Secondary checks (affect score 6-10): 5. Visual hierarchy — Title → stat banner → body flow is immediately clear 6. Figure prominence — Figures occupy 40-50% of content area 7. Color coherence — Card tints, accent stripes, and venue colors work harmoniously 8. Whitespace balance — No large empty gaps, no overly cramped sections 9. Information density — Can understand the contribution in 60 seconds 10. Overall aesthetics — Would you be proud to present this at a top venue?

Scoring:

9-10: Print-ready, no changes needed
7-8: Minor tweaks (spacing, font size adjustments)
5-6: Needs revision (layout issues, readability problems)
1-4: Major issues (clipping, fabricated data, broken layout)

Step 3: Iterative refinement loop

MAX_ITERATIONS = 5
SCORE_THRESHOLD = 9

for iteration in 1..MAX_ITERATIONS:
    1. Render poster to poster/poster_v{iteration}.png (200 DPI)
    2. Claude reads the PNG and performs STRICT visual review
    3. Score the poster (1-10) with detailed feedback
    4. If score >= SCORE_THRESHOLD → PASS, proceed to Phase 6
    5. If score < SCORE_THRESHOLD:
       a. Identify top 3 issues (ranked by visual impact)
       b. Generate targeted LaTeX fixes for each issue
       c. Apply fixes to main.tex
       d. Recompile (Phase 4 error loop)
       e. Continue to next iteration
    6. Save all versions: poster/poster_v{iteration}.png

⚠️ All versions are preserved. Never overwrite previous renders. Save as poster_v1.png, poster_v2.png, etc. This allows comparison and rollback.

⚠️ Targeted fixes only. Each iteration should fix at most 3 specific issues. Do NOT rewrite the entire LaTeX — small, focused edits prevent regression.

Optional: Gemini visual generation (if mcp__illustrator__run is available):

For poster elements that need custom illustrations (e.g., hero architecture diagram, method workflow), use the Gemini illustration pipeline:

Write a detailed specification for the illustration
Call mcp__illustrator__run with the specification
Claude reviews the generated image for accuracy
Iterate until score ≥ 9 or max 3 attempts
Save final illustration to poster/figures/ and embed in LaTeX

Step 4: Save visual review log

Append all iteration scores and feedback to poster/POSTER_VISUAL_REVIEW.md:

# Visual Review Log

## Iteration 1 — Score: 7/10
- Issue 1: Title font too small (72pt → should be 84pt+)
- Issue 2: Results figure clipped at bottom
- Issue 3: Stat banner numbers not prominent enough
- Fixes applied: [list of changes]

## Iteration 2 — Score: 9/10
- All critical checks pass
- Minor: References column slightly shorter than others
- Decision: PASS — print-ready

Phase 6: Codex Reviewer Review

Send the poster content plan + key LaTeX sections to GPT-5.5 xhigh for review.

spawn_agent:
  model: gpt-5.5
  reasoning_effort: xhigh
  message: |
    Review this academic conference poster for [VENUE].

    Evaluate using these criteria (score 1-5 each):

    1. **Information hierarchy** — Can someone understand the contribution in 60 seconds?
    2. **Text density** — Is it concise enough? (Target: 400-700 words total, bullet points only, NO abstract paragraph)
    3. **Figure prominence** — Are key results visually dominant? (Target: figures occupy 40-50% of area)
    4. **Column balance** — Are columns roughly equal height?
    5. **Readability** — Font sizes appropriate for 1.5m distance? (Title ≥90pt, body ≥34pt)
    6. **Narrative flow** — Does the poster tell a left-to-right story?
    7. **Whitespace** — Is content filling the space well? No large empty gaps?

    Poster content:
    [PASTE POSTER_CONTENT_PLAN.md]

    LaTeX source:
    [PASTE key sections of main.tex]

    Provide:
    - Score for each criterion
    - Top 3 actionable fixes (ranked by impact)
    - Overall: Ready to print? (Yes / Needs revision / Major issues)

Apply CRITICAL and MAJOR fixes to poster/main.tex. Recompile if changes were made.

Save review to poster/POSTER_REVIEW.md.

⚠️ Important: After applying review fixes, proceed to Phase 6 only when the poster is finalized. PPTX and SVG must be generated from the final LaTeX/PDF — never from an intermediate version.

Phase 7: Editable Format Export

⚠️ Generate PPTX and SVG only AFTER all revisions are complete. This phase runs last (after review fixes) to ensure all formats contain identical content.

6.1 PowerPoint (.pptx)

Generate a native PPTX using python-pptx (not pandoc — pandoc conversion is lossy):

python3 -c "import pptx" 2>/dev/null || pip install python-pptx

Write a Python script poster/generate_pptx.py that:

Creates a single-slide PPTX with poster dimensions (A0 landscape: 1189mm x 841mm)
Replicates the 4-column layout using positioned text boxes
Embeds PNG figures (from poster/figures/*.png — NOT PDFs, python-pptx cannot embed PDFs)
Applies venue color scheme (primary/secondary/accent) to title bar and section headers
Keeps all text editable (not images of text)
Uses large font sizes matching the PDF (title 86pt, body 34pt, headers 42pt, stats 68pt)
Reads content from the FINAL main.tex — do NOT hardcode content separately

⚠️ PPTX font sizes must also be large. A common mistake is using small fonts (17-24pt) in the PPTX while the PDF has 34pt+. The PPTX is A0-sized so needs identical large fonts.

PPTX helper pattern:

def add_image(left, top, w, filename):
    """Add PNG image, auto-calculate height from aspect ratio."""
    path = os.path.join(FIG_DIR, filename)
    if not os.path.exists(path):
        txt(left, top, w, 60, f"[Image: {filename}]", ...)
        return top + 60
    pic = slide.shapes.add_picture(path, Mm(left), Mm(top), Mm(w))
    h_mm = pic.height / Mm(1)
    return top + h_mm

cd poster && python3 generate_pptx.py
# Output: poster/poster.pptx

6.2 SVG (for Adobe Illustrator)

Convert the compiled PDF to editable SVG. Preferred method: PyMuPDF (always available via pip, no brew/system install needed):

# Preferred: PyMuPDF (pip install pymupdf) — always works, no system deps
python3 -c "import fitz" 2>/dev/null || pip install pymupdf
python3 -c "
import fitz
doc = fitz.open('poster/main.pdf')
page = doc[0]
svg = page.get_svg_image()
with open('poster/poster.svg', 'w') as f:
    f.write(svg)
doc.close()
print('SVG saved')
"

# Fallback 1: pdf2svg (if installed)
which pdf2svg && pdf2svg poster/main.pdf poster/poster.svg

# Fallback 2: inkscape
which inkscape && inkscape poster/main.pdf --export-type=svg --export-filename=poster/poster.svg

⚠️ SVG inherits all layout issues from PDF. If the PDF has whitespace gaps or clipped figures, the SVG will too. Always fix the PDF first.

💡 PyMuPDF bonus: Can also generate PNG previews for quick visual inspection:
pix = page.get_pixmap(dpi=150)
pix.save('poster/poster_preview.png')

6.3 Component-based PPTX (Recommended — PDF→independent shapes)

⚠️ This is the recommended PPTX export method. It produces pixel-perfect output (from PDF) while keeping each poster card as an independent, movable/resizable shape in PowerPoint. The python-pptx rebuild (6.1) loses card styles, shadows, and colorboxes; the full-page image (single PNG) cannot be manipulated at all. This method is the best of both worlds.

How it works: Crop each posterbox region from the compiled PDF at 300 DPI, then embed each crop as a separate picture shape in PPTX at its exact grid position. Result: 10-15 independent shapes that can be individually selected, moved, resized, or deleted in PowerPoint.

import fitz, os, tempfile, shutil
from pptx import Presentation
from pptx.util import Mm
from pptx.dml.color import RGBColor

doc = fitz.open('poster/main.pdf')
page = doc[0]
pw, ph = page.rect.width, page.rect.height

# A0 dimensions in mm (adjust for portrait/A1)
W_mm, H_mm = 1189, 841  # landscape
# W_mm, H_mm = 841, 1189  # portrait

def pts_to_mm(x, y):
    return x / pw * W_mm, y / ph * H_mm

# ── Define regions from tcbposter grid ──
# Format: name → (col_0based, row_start, col_span, row_end)
# rows=20, columns=4 for landscape (3 for portrait)
COLS = 4
row_h = ph / 20
col_w = pw / COLS

regions = {
    "title":        (0, 0, COLS, 4),
    "stats":        (0, 4, COLS, 6),
    # ... add one entry per posterbox, matching between=rowN and rowM
    # Example for 4-column landscape:
    "background":   (0, 6, 1, 11),
    "contributions":(0, 11, 1, 16),
    "references":   (0, 16, 1, 20),
    "paradigms":    (1, 6, 1, 11),
    "models":       (1, 11, 1, 20),
    "architecture": (2, 6, 1, 10),
    "results1":     (2, 10, 1, 20),
    "hallucination":(3, 6, 1, 11),
    "ablation":     (3, 11, 1, 15),
    "takeaways":    (3, 15, 1, 20),
}

# ── Create PPTX ──
prs = Presentation()
prs.slide_width = Mm(W_mm)
prs.slide_height = Mm(H_mm)
slide = prs.slides.add_slide(prs.slide_layouts[6])

# Set background
bg = slide.background
bg.fill.solid()
bg.fill.fore_color.rgb = RGBColor(0xF5, 0xF3, 0xFF)  # venue bg color

tmpdir = tempfile.mkdtemp()
mat = fitz.Matrix(300/72, 300/72)  # 300 DPI

for name, (col, r0, span, r1) in regions.items():
    # Clip rectangle in PDF points
    clip = fitz.Rect(col * col_w, r0 * row_h,
                     (col + span) * col_w, r1 * row_h)
    pix = page.get_pixmap(matrix=mat, clip=clip)
    img_path = os.path.join(tmpdir, f"{name}.png")
    pix.save(img_path)

    # Position in mm
    left, top = pts_to_mm(clip.x0, clip.y0)
    right, bottom = pts_to_mm(clip.x1, clip.y1)

    slide.shapes.add_picture(img_path, Mm(left), Mm(top),
                             Mm(right - left), Mm(bottom - top))

prs.save('poster/poster_components.pptx')
doc.close()
shutil.rmtree(tmpdir)

⚠️ The regions dict must match your main.tex posterbox grid exactly. Parse the between=rowN and rowM values from each \posterbox to build this dict. If you add/remove cards in LaTeX, update the regions accordingly.

Output comparison:

File	Method	Components movable	Visual fidelity	Text editable	Size
`poster.pptx`	python-pptx rebuild	Yes	Approximate	Yes	~300 KB
`poster_from_pdf.pptx`	PDF→single image	No	Perfect	No	~3 MB
`poster_components.pptx`	PDF→per-card crops	Yes	Perfect	No	~2.5 MB

💡 Tip: To edit text in poster_components.pptx, add a text box on top of the card image and type your replacement text. The image underneath can be deleted or kept as reference.

Phase 8: Poster Speech Script

Generate poster/POSTER_SPEECH.md — a complete script for presenting the poster at a poster session.

Structure:

# Poster Presentation Script

**Paper**: [title]
**Venue**: [VENUE] [YEAR]
**Estimated time**: 2-3 minutes (quick walkthrough)

## Opening (15 seconds)
"Hi, thanks for stopping by! Let me give you a quick overview of our work..."

## Motivation (30 seconds)
[2-3 sentences explaining the problem and why it matters]

## Method (45 seconds)
[3-4 sentences walking through the hero figure and key approach]

## Key Results (30 seconds)
[2-3 sentences highlighting headline numbers from figures]

## Takeaway (15 seconds)
[1-2 sentences summarizing the contribution]

## Closing
"Happy to discuss any questions! Here's a QR code for the paper and code."

Key Rules

Architecture

MUST use article class, NEVER beamer. Beamer + tcbposter with 8+ enhanced boxes triggers grouping levels=255 overflow. This is an architectural constraint, not fixable by style tweaks.
NEVER use adjustbox package. Use plain \includegraphics[width=...] only.
NEVER use \usepackage[most]{tcolorbox}. It pulls listingsutf8.sty which may not be installed. Use \tcbuselibrary{poster,skins,fitting} explicitly.
Use [table]{xcolor} not {xcolor} — needed for \rowcolor in tables.

Layout

rows=20 and spacing=0mm for tight layout. Card separation via left accent stripe + drop shadow, not grid spacing.
Use between=rowN and rowM positioning. Not below=name which leaves auto-sized gaps.
All columns in a row band share identical row boundaries. Never mix row6-row11 in col 1 with row6-row10 in col 2.
Adjust row distribution to match content density. After trimming text, reduce row allocation proportionally. Cards with valign=top show all whitespace at the bottom.

Content

Less text is more. Target 300-500 words total. Each bullet: 5-8 words max. If it reads like a sentence, it's too long.
Do NOT fabricate data. All numbers must come from paper/sections/*.tex.
No abstract paragraph. Replace with stat banner (3-4 big-number callout boxes).
Figures should occupy 40-50% of poster area. Posters are visual-first.
Use \posterfig macro for all figures to ensure consistent spacing.
References: author (year). Short title. Venue — no full titles.
De-AI polish: Remove watch words (delve, pivotal, underscore, noteworthy, leverage, facilitate, harness).

Color & Design

Card backgrounds must NOT be pure white. Use subtle tints (e.g., #FFF5F3, #F0F4FF) that match each card's color family.
Poster background should be tinted (e.g., #EDD5D5 for ICML red theme), not white or near-white.
Colorbox intensity: 18-25%, not 8-12%. Faint colorboxes are invisible on print.
Left accent stripe card design (borderline west={5pt}{0pt}{color}) — cleaner than rounded colored boxes.
4 card styles (redcard/bluecard/darkcard/highlightcard) create visual rhythm across the poster.

Equations

Use $\displaystyle ...$ inside colorboxes, NOT \[...\]. Display math adds margins causing overfull hbox.
Reduce equation font to 26-28pt inside narrow colorboxes.
Wrap equations in \centering + \parbox{0.92\linewidth} for proper alignment.

Export

Copy figures, never symlink. cp not ln -sf. pdflatex can't follow symlinks.
Convert PDF figures to PNG for PPTX. python-pptx cannot embed PDFs. Use pdf2image at 300 DPI.
SVG via PyMuPDF (fitz.Page.get_svg_image()) — works everywhere, no system deps needed.
PPTX/SVG last. Generate editable exports only after ALL LaTeX revisions are finalized.
Large file handling: If the Write tool fails due to file size, use Bash (cat << 'EOF' > file) silently.

Misc

Do NOT hallucinate citations. Use only references from the paper's bibliography.
Include QR code placeholder or code link for paper/code repository.
Font size minimums (article class): Title ≥84pt, section headers ≥40pt, body ≥34pt, captions ≥26pt, references ≥30pt, stat numbers ≥66pt.
Feishu notifications are optional. If ~/.codex/feishu.json exists, send notifications. Otherwise skip.
If poster generation requires local preview, PNG review, or mcp__illustrator__run and that capability is missing in the current environment, stop and tell the user what to configure. Do not silently degrade this skill into text-only poster drafting.

Paper Poster: From Paper to Conference Poster

Generate a conference poster from: $ARGUMENTS

Context

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., /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-5.5 — 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.

💡 Override: /paper-poster "paper/" — venue: CVPR, size: A1, orientation: portrait, columns: 3

⚠️ 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.

tcbposter Layout Rules (Critical)

⚠️ The #1 cause of poster failures is content overflow. tcbposter uses a fixed grid — content that exceeds the box is silently clipped with no compilation error. You will NOT see any warning; the poster will simply be cut off.

⚠️ The #2 cause is large whitespace gaps. Using too few rows (e.g., rows=5) creates ~168mm per row on A0 landscape. If title text only needs 120mm, the remaining 48mm is wasted whitespace. Solution: use rows=20 for fine-grained control (~42mm per row).

Grid System: `rows=20` (Critical)

Use rows=20 for A0 landscape. Each row ≈ 42mm, giving precise control over section heights.

Recommended row allocation for 4-column A0 landscape:

Section	Rows	Height	Row range
Title bar	3	~126mm	`top` to `row4`
Stat banner	2	~84mm	`row4` to `row6`
Body content	14	~588mm	`row6` to `bottom`

Key principle: Always use between=rowN and rowM syntax (not below=name) for precise vertical placement. The below= syntax lets tcolorbox auto-place, which often leaves unwanted gaps.

Row Count Guidance

Poster Size	Orientation	Recommended rows	Columns	Row height
A0	landscape	20	4	~42mm
A0	portrait	20	3	~59mm
A1	landscape	16	3	~37mm
A1	portrait	20	2	~30mm

Portrait A0 Layout (3 columns, rows=20)

⚠️ Portrait A0 posters use 2-3 columns, NEVER 4. Research consensus: "Two columns is typical for a poster with a portrait orientation" (Colin Purrington, NYU poster guides). At 841mm width, 4 columns give only ~195mm per column — too narrow for readable text at poster-session distance. 3 columns (~260mm each) is the recommended default for content-rich papers. Use 2 columns for simpler posters or when figures need more horizontal space.

For portrait posters (841x1189mm), use a 3-column, 3-row-band layout:

Section	Rows	Row range	Content
Title bar	4	`top` to `row4`	Title + authors + venue (span=3)
Stat banner	2	`row4` to `row6`	3 headline stat callouts (span=3)
Row A	5	`row6` to `row11`	Background+Motivation, Method (hero fig), Key Results (fig)
Row B	5	`row11` to `row16`	Contributions, Equations+Ablation, Result 2 (fig+table)
Row C	4	`row16` to `bottom`	References+QR, Setup+Benchmarks, Key Takeaways

3-column portrait layout diagram:

┌─────────────────────────────────────┐
│         TITLE BAR (span=3)          │
├─────────────────────────────────────┤
│   Stat 1   │   Stat 2   │  Stat 3  │

├────────────┼────────────┼──────────┤
│ References │  Setup &   │   Key    │

└────────────┴────────────┴──────────┘

⚠️ All 3 columns in each row band share the same row boundaries. This ensures cross-column alignment. Never mix row6 to row11 in one column with row6 to row10 in another — it creates visual misalignment.

⚠️ Use spacing=0mm for tight layouts. Card separation is handled by card styles (left accent stripe, drop shadow), not grid spacing. Grid spacing > 2mm creates visible gaps between rows.

Modern Card Design System (Left Accent Stripe)

Instead of rounded boxes with colored headers, use a left accent stripe design. This is cleaner, more modern, and avoids the "PowerPoint box" look.

Define 4 card styles using the venue's 3-color system:

% Tinted card backgrounds (NOT pure white — adds warmth)
\definecolor{redbg}{HTML}{FFF5F3}     % warm pink tint for redcard
\definecolor{bluebg}{HTML}{F0F4FF}    % cool blue tint for bluecard
\definecolor{darkbg}{HTML}{FDF6F3}    % warm cream tint for darkcard
\definecolor{redtitlebg}{HTML}{FDEAE8}   % title bar tint
\definecolor{bluetitlebg}{HTML}{E4ECFF}
\definecolor{darktitlebg}{HTML}{F5E8E2}

\tcbset{
  redcard/.style={
    enhanced, arc=0pt, boxrule=0pt, colback=redbg,
    borderline west={5pt}{0pt}{secondary},
    left=16pt, right=14pt, top=4pt, bottom=4pt,
    fonttitle=\fontsize{40}{48}\selectfont\bfseries\color{secondary},
    coltitle=secondary, colbacktitle=redtitlebg,
    toptitle=6pt, bottomtitle=6pt,
    titlerule=2pt, titlerule style={secondary!50},
    valign=top, drop shadow={opacity=0.18},
  },
  bluecard/.style={...same pattern with accent color and bluebg...},
  darkcard/.style={...same pattern with primary color and darkbg...},
  highlightcard/.style={
    enhanced, arc=0pt, boxrule=0pt, colback=primary!18!white,
    borderline west={6pt}{0pt}{primary},
    fonttitle=...\color{white}, colbacktitle=primary,
    ...
  },
}

Card assignment pattern (creates visual rhythm):

redcard (secondary stripe): Background, Key Idea, Ablation, References, Setup
bluecard (accent stripe): Result 1, Result 2, Benchmarks, Analysis
darkcard (primary stripe): Contributions, Method
highlightcard (primary fill): Key Takeaways / Conclusion

⚠️ Card backgrounds must NOT be pure white (#FFFFFF). Use subtle tints matching the card's color family. Pure white cards on a tinted poster background look disconnected. The tint should be barely visible but adds cohesion.

Figure + Caption Macro

Define a consistent macro for all figures to ensure uniform spacing:

\newcommand{\posterfig}[3]{%
  \centering\includegraphics[width=#1\linewidth]{#2}\\[3mm]
  {\fontsize{26}{32}\selectfont\color{textgray}\textit{#3}}\vspace{2mm}%
}
% Usage: \posterfig{0.96}{figures/results.png}{Caption text here.}

⚠️ Inconsistent figure-text spacing is the #1 visual flaw in generated posters. The \posterfig macro enforces uniform 3mm gap + 2mm bottom padding across all figures.

Content Colorbox Intensity

Inside cards, use \colorbox{color!N} for highlighted blocks. The intensity N must be 18-25% (not 8-12% which is too faint):

% TOO FAINT (invisible on print):
\colorbox{primary!8}{\parbox{...}{...}}

% CORRECT (visible, distinct):
\colorbox{primary!20}{\parbox{0.94\linewidth}{...}}
\colorbox{accent!20}{\parbox{0.94\linewidth}{...}}
\colorbox{secondary!20}{\parbox{0.94\linewidth}{...}}

Similarly, \rowcolor in tables should use 15% intensity: \rowcolor{primary!15}.

Font Size Rules (A0 at article class — NO scale factor)

⚠️ Critical: When using article class (not beamerposter), there is NO automatic scale factor. All font sizes are literal. A poster viewed from 1.5m needs much larger fonts than you think.

Element	Font size	Leading	Example
Title	90pt	108pt	`\fontsize{90}{108}\selectfont`
Author line	42pt	50pt	`\fontsize{42}{50}\selectfont`
Section headers	42pt	50pt	via `fonttitle=\fontsize{42}{50}...`
Sub-headers	38pt	46pt	`\subheader{}{}` command
Body text	34pt	44pt	`\fontsize{34}{44}\selectfont`
Stat callout numbers	72pt	86pt	`\fontsize{72}{86}\selectfont`
Stat callout labels	30pt	36pt	`\fontsize{30}{36}\selectfont`
Equations	32pt	40pt	`\fontsize{32}{40}\selectfont`
Table cells	30pt	38pt	`\fontsize{30}{38}\selectfont`
Figure captions	28pt	34pt	`\fontsize{28}{34}\selectfont`
References	30pt	40pt	`\fontsize{30}{40}\selectfont`

⚠️ Lesson learned from testing: Body text at 20pt on A0 is unreadable from more than 0.5m. 34pt is the minimum for comfortable reading at poster-session distance.

Content Budget

Total target: 300-500 words (excluding figure captions and stat callout numbers).

⚠️ The #1 content mistake is too much text. A poster is NOT a paper summary — it's a visual guide. Each bullet should be a key phrase (5-8 words), not a sentence. If you find yourself writing full sentences, you're putting too much text.

⚠️ Content density calibration: When in doubt, use LESS text. It's much easier to add a few words than to trim dense paragraphs. Target ~70% fill per card (some breathing room), NOT 100%.

Box type	Max bullets	Max words	Figure?	Style
Background	3	40-60	No	Short bullets + 1 key insight colorbox
Key Idea / Architecture	0-1	20-30	Yes (hero fig)	Figure dominant + 2 one-liner colorboxes
Contributions	3-4	60-80	No	Numbered, 1 line each
Method	2-3	40-60	No	2 equation colorboxes + 3 short bullets
Results (each)	2-3	30-50	Yes (figure)	Figure + 2-3 one-line colorboxes
Ablation	3	30-40	No	3 colorboxes, 2 lines each max
Analysis	3	30-50	Yes (figure)	Figure + 3 one-line colorboxes
References	4-5	30-40	No	Author (year). Short title. Venue
Setup	4-5	30-40	No	5 one-liner colorboxes
Benchmarks	0	20	No	Table + 1-line caption
Key Takeaways	3	30-40	No	3 short items + code link

Bullet point rules:

Maximum 8 words per bullet when possible
Use $\Rightarrow$ and $\to$ for causal arrows instead of words
Numbers > words: "42% less memory" not "reduces memory usage by 42 percent"
Colorbox labels: "vs. Depth: 4L CoE ≈ 12L MoE, 42% less memory" (one line)

Workflow

Phase 0: Input Validation & Setup

Check prerequisites:

which pdflatex && which latexmk

If LaTeX is NOT installed, try in order:

# Option 1: brew cask (requires sudo — may fail in non-interactive shells)
brew install --cask mactex-no-gui

# Option 2: BasicTeX (smaller, may still need sudo)
brew install --cask basictex

# Option 3: User-directory install (NO sudo needed — always works)
curl -L https://mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz | tar xz
cd install-tl-*

tlpdbopt_install_docfiles 0
tlpdbopt_install_srcfiles 0
PROF
./install-tl --profile=texlive.profile
export PATH="$HOME/texlive/YYYY/bin/universal-darwin:$PATH"

After installation, install required packages:

tlmgr install tcolorbox pgf etoolbox environ trimspaces \
  type1cm pdfcol tikzfill latexmk lm enumitem geometry

⚠️ Lesson learned: brew install --cask mactex-no-gui often fails in non-interactive shells because the macOS installer requires sudo password. The user-directory TeX Live install (Option 3) always works without sudo.

⚠️ Do NOT install or use beamerposter. The article class approach does not need it.

Verify paper exists:

ls $PAPER_DIR/main.tex || ls $PAPER_DIR/main.pdf
ls $PAPER_DIR/sections/*.tex
ls $PAPER_DIR/figures/

Backup existing poster: if poster/ exists, copy to poster-backup-{timestamp}/
Create output directory: mkdir -p poster/figures

Copy figures to poster directory:

# IMPORTANT: Use cp, NOT ln -sf (symlinks)
# pdflatex often fails to resolve symlinks across directories
cp paper/figures/selected_figure.pdf poster/figures/

⚠️ Never use symlinks for poster figures. pdflatex cannot reliably follow symlinks across directories. Always cp the actual files.

Convert PDF figures to PNG for PPTX embedding:

python3 -c "import pdf2image" 2>/dev/null || pip install pdf2image
# For each figure:
python3 -c "
from pdf2image import convert_from_path
for name in ['paradigm', 'architecture', 'results', 'hallucination']:
    imgs = convert_from_path(f'poster/figures/{name}.pdf', dpi=300)
    imgs[0].save(f'poster/figures/{name}.png', 'PNG')
"

⚠️ python-pptx CANNOT embed PDF images. You MUST convert to PNG first. This is a hard limitation of the OOXML format. Always generate PNG copies at 300 DPI during setup.

Detect CJK: if paper contains Chinese/Japanese/Korean text, set ENGINE to xelatex
Check for resume: read poster/POSTER_STATE.json if it exists

Phase 1: Content Extraction

Read each section from paper/sections/*.tex and extract poster-appropriate content:

Extraction rules — a poster shows ~30-40% of the paper's content:

Paper Section	Poster Extraction	Target Length
Abstract	Skip — replace with 2-4 big-number stat callout boxes spanning all columns	0 words (numbers only)
Introduction	Motivation: 2-3 bullet points + numbered contribution list (4 items)	120-160 words
Method	1 hero architecture figure + key equations + 3-5 bullet points	80-120 words
Experiments	Dataset details + main result figures + numeric stat tables + ablation	150-200 words
Conclusion	3-4 key findings + 2-3 next steps	60-80 words
Related Work	Skip entirely — no space on poster	0

Total target: 400-700 words (excluding figure captions and stat callout numbers).

⚠️ No abstract paragraph on poster. Replace with a stat banner: 3-4 large-number callout boxes showing headline results. This is the single highest-impact change for 60-second comprehension.

Output: poster/POSTER_CONTENT_PLAN.md — structured markdown showing exactly what goes where, with word counts per box.

🚦 Checkpoint:

📋 Poster content plan ready:
- Title: [paper title]
- Venue: [VENUE] ([POSTER_SIZE] [ORIENTATION])
- Layout: [COLUMNS] columns, rows=20
- Figures selected: [N] figures
- Boxes per column: Col1=[N], Col2=[N], Col3=[N], Col4=[N]
- Estimated word count: [N] words

Proceed with this layout? Or adjust content selection?

⛔ STOP HERE and wait for user response.

State: Write POSTER_STATE.json with phase: 1.

Phase 2: Figure Selection & Layout

Inventory all figures in paper/figures/:

ls -la paper/figures/*.{pdf,png,jpg,svg} 2>/dev/null

Rank by poster importance:
- Tier 1 (must include): Architecture/method overview diagram, main results plot
- Tier 2 (include if space): Ablation bar chart, qualitative examples, experimental paradigm
- Tier 3 (skip): Appendix figures, supplementary plots, tables-as-figures
Select top 3-5 figures that fit the 4-column layout
Copy figures to poster directory (NOT symlinks) + convert PDF→PNG for PPTX
Design column layout — 4-column IMRAD:
- Col 1: Background & Motivation + Contributions + References & QR
- Col 2: Dataset & Paradigms (fig) + Computational Models (equations)
- Col 3: Architecture (fig) + Result 1 (fig + stat table)
- Col 4: Result 2 (fig + stat table) + Ablation + Conclusion

Phase 3: Generate Poster LaTeX

Create poster/main.tex using article class + geometry + tcbposter.

⚠️ Equations in narrow colorboxes: Display math \[...\] adds horizontal margins that cause overfull hbox errors inside \colorbox{\parbox{}}. Always use $\displaystyle ...$ with \centering instead. Reduce equation font to 26-28pt inside colorboxes.

🚦 Checkpoint:

🖼️ Poster LaTeX generated:
- Template: article + tcbposter (rows=20)
- Layout: [COLUMNS] columns, [ORIENTATION] [POSTER_SIZE]
- Colors: [VENUE] theme (primary: [HEX] / secondary: [HEX] / accent: [HEX])
- Figures: [N] embedded
- Font sizes: title=90pt, body=34pt, headers=42pt
- Word count: ~[N] words

Compile now?

⛔ STOP HERE and wait for user response.

State: Write POSTER_STATE.json with phase: 3.

Phase 4: Compile Poster

cd poster && latexmk -pdf -interaction=nonstopmode main.tex

⚠️ If using user-directory TeX Live, prepend PATH: export PATH="$HOME/texlive/YYYY/bin/universal-darwin:$PATH"

Error handling loop (max 3 attempts):

Parse error log for the first error
Fix the most likely cause:
- grouping levels=255 → STOP. Switch from beamer to article class. This is not fixable by removing styles.
- Missing package → tlmgr install <package>
- File not found: adjustbox.sty → Remove \usepackage{adjustbox} and any max height options
- File not found → verify poster/figures/ has the file (not a broken symlink)
- Overfull boxes → reduce text or figure size
Recompile

Common missing packages (install proactively if not present):

tlmgr install type1cm pdfcol tikzfill

Verification:

pdfinfo poster/main.pdf
# Check: Pages: 1, Page size: ~3370.39 x 2383.94 pts (A0 landscape)

Visual inspection after compilation:

All 4 columns have content visible to the bottom — no silent clipping
No large whitespace gaps between title/stats and body content
Figures are fully visible, not cut off
Text is readable (zoom to 100% = actual A0 size)

Phase 5: Visual Review via Claude + Gemini (Iterative Refinement)

This phase uses Claude visual assessment on rendered poster images to iteratively refine layout, readability, and visual hierarchy — similar to the paper-illustration skill's review loop.

Step 1: Render poster to PNG preview

import fitz
doc = fitz.open('poster/main.pdf')
page = doc[0]
pix = page.get_pixmap(dpi=200)  # 200 DPI for visual review (higher than 150 preview)
pix.save('poster/poster_review.png')
doc.close()

Step 2: Claude visual assessment

Read the rendered poster/poster_review.png and perform a STRICT visual review with the following rubric (score 1-10):

Critical checks (must all pass, any failure = score ≤ 5):

Content accuracy — No fabricated data, all numbers match paper
Text readability — All text readable at simulated 1.5m distance (no text too small)
No clipping — All content visible, no cut-off figures or text
Column alignment — Row bands align across all columns

Scoring:

9-10: Print-ready, no changes needed
7-8: Minor tweaks (spacing, font size adjustments)
5-6: Needs revision (layout issues, readability problems)
1-4: Major issues (clipping, fabricated data, broken layout)

Step 3: Iterative refinement loop

MAX_ITERATIONS = 5
SCORE_THRESHOLD = 9

for iteration in 1..MAX_ITERATIONS:
    1. Render poster to poster/poster_v{iteration}.png (200 DPI)
    2. Claude reads the PNG and performs STRICT visual review
    3. Score the poster (1-10) with detailed feedback
    4. If score >= SCORE_THRESHOLD → PASS, proceed to Phase 6
    5. If score < SCORE_THRESHOLD:
       a. Identify top 3 issues (ranked by visual impact)
       b. Generate targeted LaTeX fixes for each issue
       c. Apply fixes to main.tex
       d. Recompile (Phase 4 error loop)
       e. Continue to next iteration
    6. Save all versions: poster/poster_v{iteration}.png

⚠️ All versions are preserved. Never overwrite previous renders. Save as poster_v1.png, poster_v2.png, etc. This allows comparison and rollback.

⚠️ Targeted fixes only. Each iteration should fix at most 3 specific issues. Do NOT rewrite the entire LaTeX — small, focused edits prevent regression.

Optional: Gemini visual generation (if mcp__illustrator__run is available):

For poster elements that need custom illustrations (e.g., hero architecture diagram, method workflow), use the Gemini illustration pipeline:

Write a detailed specification for the illustration
Call mcp__illustrator__run with the specification
Claude reviews the generated image for accuracy
Iterate until score ≥ 9 or max 3 attempts
Save final illustration to poster/figures/ and embed in LaTeX

Step 4: Save visual review log

Append all iteration scores and feedback to poster/POSTER_VISUAL_REVIEW.md:

# Visual Review Log

## Iteration 1 — Score: 7/10
- Issue 1: Title font too small (72pt → should be 84pt+)
- Issue 2: Results figure clipped at bottom
- Issue 3: Stat banner numbers not prominent enough
- Fixes applied: [list of changes]

## Iteration 2 — Score: 9/10
- All critical checks pass
- Minor: References column slightly shorter than others
- Decision: PASS — print-ready

Phase 6: Codex Reviewer Review

Send the poster content plan + key LaTeX sections to GPT-5.5 xhigh for review.

spawn_agent:
  model: gpt-5.5
  reasoning_effort: xhigh
  message: |
    Review this academic conference poster for [VENUE].

    Evaluate using these criteria (score 1-5 each):

    1. **Information hierarchy** — Can someone understand the contribution in 60 seconds?
    2. **Text density** — Is it concise enough? (Target: 400-700 words total, bullet points only, NO abstract paragraph)
    3. **Figure prominence** — Are key results visually dominant? (Target: figures occupy 40-50% of area)
    4. **Column balance** — Are columns roughly equal height?
    5. **Readability** — Font sizes appropriate for 1.5m distance? (Title ≥90pt, body ≥34pt)
    6. **Narrative flow** — Does the poster tell a left-to-right story?
    7. **Whitespace** — Is content filling the space well? No large empty gaps?

    Poster content:
    [PASTE POSTER_CONTENT_PLAN.md]

    LaTeX source:
    [PASTE key sections of main.tex]

    Provide:
    - Score for each criterion
    - Top 3 actionable fixes (ranked by impact)
    - Overall: Ready to print? (Yes / Needs revision / Major issues)

Apply CRITICAL and MAJOR fixes to poster/main.tex. Recompile if changes were made.

Save review to poster/POSTER_REVIEW.md.

⚠️ Important: After applying review fixes, proceed to Phase 6 only when the poster is finalized. PPTX and SVG must be generated from the final LaTeX/PDF — never from an intermediate version.

Phase 7: Editable Format Export

⚠️ Generate PPTX and SVG only AFTER all revisions are complete. This phase runs last (after review fixes) to ensure all formats contain identical content.

6.1 PowerPoint (.pptx)

Generate a native PPTX using python-pptx (not pandoc — pandoc conversion is lossy):

python3 -c "import pptx" 2>/dev/null || pip install python-pptx

Write a Python script poster/generate_pptx.py that:

Creates a single-slide PPTX with poster dimensions (A0 landscape: 1189mm x 841mm)
Replicates the 4-column layout using positioned text boxes
Embeds PNG figures (from poster/figures/*.png — NOT PDFs, python-pptx cannot embed PDFs)
Applies venue color scheme (primary/secondary/accent) to title bar and section headers
Keeps all text editable (not images of text)
Uses large font sizes matching the PDF (title 86pt, body 34pt, headers 42pt, stats 68pt)
Reads content from the FINAL main.tex — do NOT hardcode content separately

⚠️ PPTX font sizes must also be large. A common mistake is using small fonts (17-24pt) in the PPTX while the PDF has 34pt+. The PPTX is A0-sized so needs identical large fonts.

PPTX helper pattern:

def add_image(left, top, w, filename):
    """Add PNG image, auto-calculate height from aspect ratio."""
    path = os.path.join(FIG_DIR, filename)
    if not os.path.exists(path):
        txt(left, top, w, 60, f"[Image: {filename}]", ...)
        return top + 60
    pic = slide.shapes.add_picture(path, Mm(left), Mm(top), Mm(w))
    h_mm = pic.height / Mm(1)
    return top + h_mm

cd poster && python3 generate_pptx.py
# Output: poster/poster.pptx

6.2 SVG (for Adobe Illustrator)

Convert the compiled PDF to editable SVG. Preferred method: PyMuPDF (always available via pip, no brew/system install needed):

# Preferred: PyMuPDF (pip install pymupdf) — always works, no system deps
python3 -c "import fitz" 2>/dev/null || pip install pymupdf
python3 -c "
import fitz
doc = fitz.open('poster/main.pdf')
page = doc[0]
svg = page.get_svg_image()
with open('poster/poster.svg', 'w') as f:
    f.write(svg)
doc.close()
print('SVG saved')
"

# Fallback 1: pdf2svg (if installed)
which pdf2svg && pdf2svg poster/main.pdf poster/poster.svg

# Fallback 2: inkscape
which inkscape && inkscape poster/main.pdf --export-type=svg --export-filename=poster/poster.svg

⚠️ SVG inherits all layout issues from PDF. If the PDF has whitespace gaps or clipped figures, the SVG will too. Always fix the PDF first.

💡 PyMuPDF bonus: Can also generate PNG previews for quick visual inspection:
pix = page.get_pixmap(dpi=150)
pix.save('poster/poster_preview.png')

6.3 Component-based PPTX (Recommended — PDF→independent shapes)

⚠️ This is the recommended PPTX export method. It produces pixel-perfect output (from PDF) while keeping each poster card as an independent, movable/resizable shape in PowerPoint. The python-pptx rebuild (6.1) loses card styles, shadows, and colorboxes; the full-page image (single PNG) cannot be manipulated at all. This method is the best of both worlds.

import fitz, os, tempfile, shutil
from pptx import Presentation
from pptx.util import Mm
from pptx.dml.color import RGBColor

doc = fitz.open('poster/main.pdf')
page = doc[0]
pw, ph = page.rect.width, page.rect.height

# A0 dimensions in mm (adjust for portrait/A1)
W_mm, H_mm = 1189, 841  # landscape
# W_mm, H_mm = 841, 1189  # portrait

def pts_to_mm(x, y):
    return x / pw * W_mm, y / ph * H_mm

# ── Define regions from tcbposter grid ──
# Format: name → (col_0based, row_start, col_span, row_end)
# rows=20, columns=4 for landscape (3 for portrait)
COLS = 4
row_h = ph / 20
col_w = pw / COLS

regions = {
    "title":        (0, 0, COLS, 4),
    "stats":        (0, 4, COLS, 6),
    # ... add one entry per posterbox, matching between=rowN and rowM
    # Example for 4-column landscape:
    "background":   (0, 6, 1, 11),
    "contributions":(0, 11, 1, 16),
    "references":   (0, 16, 1, 20),
    "paradigms":    (1, 6, 1, 11),
    "models":       (1, 11, 1, 20),
    "architecture": (2, 6, 1, 10),
    "results1":     (2, 10, 1, 20),
    "hallucination":(3, 6, 1, 11),
    "ablation":     (3, 11, 1, 15),
    "takeaways":    (3, 15, 1, 20),
}

# ── Create PPTX ──
prs = Presentation()
prs.slide_width = Mm(W_mm)
prs.slide_height = Mm(H_mm)
slide = prs.slides.add_slide(prs.slide_layouts[6])

# Set background
bg = slide.background
bg.fill.solid()
bg.fill.fore_color.rgb = RGBColor(0xF5, 0xF3, 0xFF)  # venue bg color

tmpdir = tempfile.mkdtemp()
mat = fitz.Matrix(300/72, 300/72)  # 300 DPI

for name, (col, r0, span, r1) in regions.items():
    # Clip rectangle in PDF points
    clip = fitz.Rect(col * col_w, r0 * row_h,
                     (col + span) * col_w, r1 * row_h)
    pix = page.get_pixmap(matrix=mat, clip=clip)
    img_path = os.path.join(tmpdir, f"{name}.png")
    pix.save(img_path)

    # Position in mm
    left, top = pts_to_mm(clip.x0, clip.y0)
    right, bottom = pts_to_mm(clip.x1, clip.y1)

    slide.shapes.add_picture(img_path, Mm(left), Mm(top),
                             Mm(right - left), Mm(bottom - top))

prs.save('poster/poster_components.pptx')
doc.close()
shutil.rmtree(tmpdir)

⚠️ The regions dict must match your main.tex posterbox grid exactly. Parse the between=rowN and rowM values from each \posterbox to build this dict. If you add/remove cards in LaTeX, update the regions accordingly.

Output comparison:

File	Method	Components movable	Visual fidelity	Text editable	Size
`poster.pptx`	python-pptx rebuild	Yes	Approximate	Yes	~300 KB
`poster_from_pdf.pptx`	PDF→single image	No	Perfect	No	~3 MB
`poster_components.pptx`	PDF→per-card crops	Yes	Perfect	No	~2.5 MB

💡 Tip: To edit text in poster_components.pptx, add a text box on top of the card image and type your replacement text. The image underneath can be deleted or kept as reference.

Phase 8: Poster Speech Script

Generate poster/POSTER_SPEECH.md — a complete script for presenting the poster at a poster session.

Structure:

# Poster Presentation Script

**Paper**: [title]
**Venue**: [VENUE] [YEAR]
**Estimated time**: 2-3 minutes (quick walkthrough)

## Opening (15 seconds)
"Hi, thanks for stopping by! Let me give you a quick overview of our work..."

## Motivation (30 seconds)
[2-3 sentences explaining the problem and why it matters]

## Method (45 seconds)
[3-4 sentences walking through the hero figure and key approach]

## Key Results (30 seconds)

Key Rules

Architecture

MUST use article class, NEVER beamer. Beamer + tcbposter with 8+ enhanced boxes triggers grouping levels=255 overflow. This is an architectural constraint, not fixable by style tweaks.
NEVER use adjustbox package. Use plain \includegraphics[width=...] only.
NEVER use \usepackage[most]{tcolorbox}. It pulls listingsutf8.sty which may not be installed. Use \tcbuselibrary{poster,skins,fitting} explicitly.
Use [table]{xcolor} not {xcolor} — needed for \rowcolor in tables.

Layout

rows=20 and spacing=0mm for tight layout. Card separation via left accent stripe + drop shadow, not grid spacing.
Use between=rowN and rowM positioning. Not below=name which leaves auto-sized gaps.
All columns in a row band share identical row boundaries. Never mix row6-row11 in col 1 with row6-row10 in col 2.
Adjust row distribution to match content density. After trimming text, reduce row allocation proportionally. Cards with valign=top show all whitespace at the bottom.

Content

Less text is more. Target 300-500 words total. Each bullet: 5-8 words max. If it reads like a sentence, it's too long.
Do NOT fabricate data. All numbers must come from paper/sections/*.tex.
No abstract paragraph. Replace with stat banner (3-4 big-number callout boxes).
Figures should occupy 40-50% of poster area. Posters are visual-first.
Use \posterfig macro for all figures to ensure consistent spacing.
References: author (year). Short title. Venue — no full titles.
De-AI polish: Remove watch words (delve, pivotal, underscore, noteworthy, leverage, facilitate, harness).

Color & Design

Card backgrounds must NOT be pure white. Use subtle tints (e.g., #FFF5F3, #F0F4FF) that match each card's color family.
Poster background should be tinted (e.g., #EDD5D5 for ICML red theme), not white or near-white.
Colorbox intensity: 18-25%, not 8-12%. Faint colorboxes are invisible on print.
Left accent stripe card design (borderline west={5pt}{0pt}{color}) — cleaner than rounded colored boxes.
4 card styles (redcard/bluecard/darkcard/highlightcard) create visual rhythm across the poster.

Equations

Use $\displaystyle ...$ inside colorboxes, NOT \[...\]. Display math adds margins causing overfull hbox.
Reduce equation font to 26-28pt inside narrow colorboxes.
Wrap equations in \centering + \parbox{0.92\linewidth} for proper alignment.

Export

Copy figures, never symlink. cp not ln -sf. pdflatex can't follow symlinks.
Convert PDF figures to PNG for PPTX. python-pptx cannot embed PDFs. Use pdf2image at 300 DPI.
SVG via PyMuPDF (fitz.Page.get_svg_image()) — works everywhere, no system deps needed.
PPTX/SVG last. Generate editable exports only after ALL LaTeX revisions are finalized.
Large file handling: If the Write tool fails due to file size, use Bash (cat << 'EOF' > file) silently.

Misc

Do NOT hallucinate citations. Use only references from the paper's bibliography.
Include QR code placeholder or code link for paper/code repository.
Font size minimums (article class): Title ≥84pt, section headers ≥40pt, body ≥34pt, captions ≥26pt, references ≥30pt, stat numbers ≥66pt.
Feishu notifications are optional. If ~/.codex/feishu.json exists, send notifications. Otherwise skip.
If poster generation requires local preview, PNG review, or mcp__illustrator__run and that capability is missing in the current environment, stop and tell the user what to configure. Do not silently degrade this skill into text-only poster drafting.
