my-little-poster

A Claude Code skill that generates a print-ready academic conference poster from a paper — clean academic by default, or fully themed (it can even paint your poster in a described style via fal.ai Nano Banana Pro).

Input: a paper (preprint URL or local PDF) and a target venue (conference/workshop name or explicit dimensions). Output:

• a self-contained, browser-editable index.html, and
• a print-ready poster.pdf at the exact physical size, with a QR code to the paper.

The skill opens with a short interview (poster size, color style, logos), resolves the venue's size requirements, extracts the title/results/figures from the paper, fetches the real author list from OpenReview when the PDF is anonymized, and lays everything out in a billboard format (Morrison "Better Poster").

Presets are included for common venues (e.g. ICML workshop: portrait 24x36 in / 61x91 cm) and several color styles.

Requirements

• Claude Code.
• Python 3. The figure and QR scripts auto-install their dependencies (pymupdf, segno, Pillow) on first use, or install them with pip install -r requirements.txt.
• Google Chrome or Chromium, used headless to export the PDF at the exact size.
• Optional: poppler. Not required; figure extraction uses PyMuPDF.
• Optional: a fal.ai API key (FAL_KEY) — for higher-quality, bespoke themed art generated with Nano Banana Pro when you describe a custom style. Without it, the skill uses web-sourced art instead.

Install

Clone and run the installer:

git clone https://github.com/zj-karina/my-little-poster.git
cd my-little-poster
./install.sh

install.sh symlinks the skill into ~/.claude/skills/conference-poster, so git pull keeps it current. Use --copy to copy instead of symlink.

Manual alternative, clone directly into the skills directory:

git clone https://github.com/zj-karina/my-little-poster.git \
  ~/.claude/skills/conference-poster

Restart Claude Code or start a new session.

Usage

Examples:

• Make a poster for NeurIPS 2025, paper: https://arxiv.org/abs/2403.12345
• Build a 48x36 landscape poster from ~/papers/mywork.pdf
• Turn an OpenReview link into an ICML workshop poster

Output is written to ./poster/<paper-slug>/.

How it works

The scripts are usable standalone:

python3 scripts/fetch_pdf.py 2403.12345 paper.pdf
python3 scripts/fetch_openreview_meta.py https://openreview.net/forum?id=XXXX
python3 scripts/fig_to_png.py figures/fig1.pdf centerpiece.png --dpi 300
python3 scripts/fetch_logo.py openai.com logo.png
python3 scripts/make_qr.py https://arxiv.org/abs/2403.12345 qr.png
bash    scripts/export_pdf.sh index.html poster.pdf 24 36

Customizing

• Size and orientation: set :root --w/--h and @page { size: ... } in index.html (they must match). Portrait is taller; landscape is wider, in which case widen .support to three columns.
• Color and type: accent color and type sizes are CSS variables at the top of the template. Named palettes are in reference/styles.md.
• Venue presets: edit the table in reference/poster-specs.md.

Design checklist: reference/design-rules.md.
