What it does
posterly turns a paper into a poster for ICML, NeurIPS, ICLR, CVPR or any size the user sets. The agent lays the poster out in HTML and CSS with exact sheet dimensions through `@page` and typesets formulas with MathJax. Before delivery the checks in `tools/poster_check.py` run: `preflight`, `measure` and `polish` find column overflow, misalignment and off-palette colours. `render_preview.py` builds a preview and the final PDF comes from Playwright. For each paper the agent composes its own choice of layout, fonts, density and masthead; the README shows nine directions for one work.
Who it is for. PhD students and researchers who need a conference poster with checked layout and no LaTeX poster packages.
Good fit when
- A conference needs a poster exactly sized to the board, for example 60 by 36 inches.
- Poster columns overflow and this should be caught by a command rather than by eye.
- Several different designs from one paper are wanted so the best can be picked.
- Formulas and tables of the paper must reach the poster without manual rework.
Not a fit when
- A ready LaTeX template is required by the organisers.
- Chromium and Python dependencies cannot be installed on the machine.
- The agent copes poorly with long design iterations.
Example request
Make a 60 by 36 inch poster from this paper, run `preflight` and `measure`, and show the preview before the PDF is produced.Limitations
It needs Python 3.10 or newer, the `playwright` package with Chromium and the system `pdfinfo` utility from poppler. Install dependencies into a dedicated environment, not the base one. The repository is licensed AGPL v3, which matters when embedding it in a product. The README advises not setting model effort above `high`, since the agent then starts second-guessing and drifts from the layout. A paid cloud service exists at tryposterly.com, while the skill itself runs free on your computer.
How to disable. Delete the `~/.claude/skills/posterly` directory and the separate Python environment created for the skill.
FAQ
How is the poster checked?
With the `preflight`, `measure` and `polish` commands from `tools/poster_check.py`. They look for overflow, misalignment and palette deviations before the PDF is produced.
Why HTML and CSS rather than LaTeX?
CSS edits show instantly, flexbox and grid are available, and the question whether a column overflows becomes a Playwright geometry query.
How do I install the skill?
Ask the agent: "Install this skill for me" with the repository link. It clones it, installs dependencies and runs the smoke test. The same manual steps are in the README.
Is payment required?
Not for the skill, which runs locally. The cloud service tryposterly.com is separate and paid, with a receipt per order.
What poster size can I set?
Any canvas: ICML, NeurIPS, ICLR, CVPR or a custom size. The `@page` directive fixes exact dimensions, for example 60 by 36 inches, and the PDF matches them.

README in short
The poster is built as one HTML and CSS file. Command checks find overflow before printing and Chromium outputs a PDF of exact size.
