phase-poster

The poster phase generates a publication-ready academic conference poster as a LaTeX .tex file, compiled to PDF. Content is extracted from .neuroflow/ project memory. The poster goes through an iterative critic loop (up to 3 cycles) before final output.

---

Approach

1. Confirm conference name, target size, orientation, and QR code URL with the user before loading any files
2. Read .neuroflow/project_config.md and relevant phase flow.md files to extract title, authors, affiliations, key findings, methods, and figures
3. Select the appropriate LaTeX template (see below)
4. Generate the full .tex source with a QR code block if a URL is provided
5. Run the poster through the poster-critic agent for iterative review (worker-critic loop, max 3 cycles)
6. Save approved .tex and compiled PDF instructions to .neuroflow/poster/

Template selection guide

Size	Orientation	Use when
A0 (841×1189 mm)	Portrait	Most European conferences; SfN, Bernstein, OHBM
A0 (1189×841 mm)	Landscape	Wide-format boards; when you have many side-by-side figures
A1 (594×841 mm)	Portrait	Lab retreats, seminars, smaller venues
90×120 cm	Portrait	Common European conference custom size
48×36 in	Landscape	US conferences (NeurIPS, COSYNE, SfN US booths)

When the user does not specify a size, ask. Default to A0 Portrait if they are unsure.

---

QR code integration

The qrcode LaTeX package is used for QR code generation. Install via TeX Live / MiKTeX:

tlmgr install qrcode

Usage in templates:

\qrcode[height=4cm]{https://your-url-here.com}

Recommended QR code targets:

• OSF preregistration URL
• bioRxiv preprint DOI (https://doi.org/10.1101/XXXX.XX.XX.XXXXXXXX)
• GitHub repository URL
• Personal lab page

If the user has not provided a URL, ask. If they want to skip the QR code, remove the \qrcode block from the footer.

---

Compilation

Compile with pdflatex (recommended for tikzposter):

pdflatex poster.tex

Or with latexmk for automatic dependency resolution:

latexmk -pdf poster.tex

Dependencies: tikzposter, qrcode, graphicx, booktabs, amsmath. All available in TeX Live ≥ 2020 and MiKTeX.

Figure formats: Use .pdf or .eps for vector figures, .png/.jpg for bitmaps. Avoid .svg directly (convert to .pdf first via Inkscape: inkscape figure.svg --export-pdf=figure.pdf).

---

Content extraction from .neuroflow/

When populating poster fields, read in this order:

1. .neuroflow/project_config.md — project title, PI, affiliation, modality, target journal
2. .neuroflow/ideation/ — research question, hypotheses, key references
3. .neuroflow/data-analyze/ or latest analysis flow.md — key results, effect sizes, figure paths
4. .neuroflow/preregistration/ — objectives and analysis plan (if available)
5. .neuroflow/paper/ — if a draft exists, extract the abstract and conclusions

If figures are referenced in flow.md files, list them for the user — do not attempt to embed binary image files; output their paths as \includegraphics stubs so the user can place the actual files.

---

Output paths

Save poster files to .neuroflow/poster/:

.neuroflow/poster/
├── poster-YYYY-MM-DD.tex          ← LaTeX source
├── figures/                       ← symlinks or stubs for figures
└── critic-log.md                  ← iterative review log

If a same-date .tex file exists, append -v2, -v3, etc.

---

Relevant skills

• neuroflow:neuroflow-core — read first; defines the command lifecycle and .neuroflow/ write rules
• neuroflow:humanizer — apply to all text blocks (Introduction, Methods, Results, Discussion, Conclusions) to strip AI signatures, fix rhythm, and calibrate register before saving the .tex file

Slash command

/neuroflow:poster — runs this workflow as a slash command.
