Generate conference presentation slides (beamer LaTeX → PDF + editable PPTX) from a compiled paper, with speaker notes and full talk script. Use when user says "PPT 만들기", "슬라이드 만들기", "make slides", "conference talk", "presentation slides", "슬라이드 생성", "발표 원고 쓰기", or wants beamer slides for a conference talk.
Override for Codex users who want Gemini, not a Codex-MCP reviewer, to act as the reviewer. Install this package after
skills/skills-codex/*.
Generate conference presentation slides from: $ARGUMENTS
This skill runs after Workflow 3 (/paper-writing). It takes a compiled paper and generates a presentation slide deck for conference oral talks, spotlight presentations, or poster lightning talks.
Unlike posters (single page, visual-first), slides tell a temporal story: each slide builds on the previous one, with progressive revelation of the research narrative. A good talk makes the audience understand why this matters before showing what was done.
NeurIPS — Target venue, determines color scheme. Supported: NeurIPS, ICML, ICLR, AAAI, ACL, EMNLP, CVPR, ECCV, GENERIC. Override via argument.spotlight — Talk format. Options: oral (15-20 min), spotlight (5-8 min), poster-talk (3-5 min), invited (30-45 min). Determines slide count and content depth.16:9 — Slide aspect ratio. Options: 16:9 (default, modern projectors), 4:3 (legacy).\note{} blocks in beamer and corresponding PPTX notes. Set false for clean slides without notes.paper/ — Directory containing the compiled paper.slides/ — Output directory for all slide files.gemini-review — Gemini reviewer invoked through the local gemini-review MCP bridge for slide review.latexmk — LaTeX build tool.pdflatex — LaTeX engine. Use xelatex for CJK text.💡 Override:
/paper-slides "paper/" — talk_type: oral, venue: ICML, minutes: 20, aspect: 4:3
| Talk Type | Duration | Slides | Content Depth |
|---|---|---|---|
poster-talk | 3-5 min | 5-8 | Problem + 1 method slide + 1 result + conclusion |
spotlight | 5-8 min | 8-12 | Problem + 2 method + 2 results + conclusion |
oral | 15-20 min | 15-22 | Full story with motivation, method detail, experiments, analysis |
invited | 30-45 min | 25-40 | Comprehensive: background, related work, deep method, extensive results, discussion |
Same as /paper-poster:

Persist state to slides/SLIDES_STATE.json after each phase:
{
"phase": 3,
"venue": "NeurIPS",

"codex_thread_id": "019cfcf4-...",
"status": "in_progress",
"timestamp": "2026-03-18T15:00:00"
}
On startup: if SLIDES_STATE.json exists with "status": "in_progress" and within 24h → resume. Otherwise → fresh start.
Check prerequisites:
which pdflatex && which latexmk
Verify paper exists:
ls $PAPER_DIR/main.tex || ls $PAPER_DIR/main.pdf
ls $PAPER_DIR/sections/*.tex
ls $PAPER_DIR/figures/
Backup existing slides: if slides/ exists, copy to slides-backup-{timestamp}/
Create output directory: mkdir -p slides/figures
Detect CJK: if paper contains Chinese/Japanese/Korean, set ENGINE to xelatex
Determine slide count: from TALK_TYPE and TALK_MINUTES using the table above
Check for resume: read slides/SLIDES_STATE.json if it exists
State: Write SLIDES_STATE.json with phase: 0.
Read paper/sections/*.tex and build a slide-by-slide outline.

For each slide in the outline, draft the actual content.
Presentation rules (enforced strictly):
| Rule | Rationale |
|---|---|
| One message per slide | If a slide has two ideas, split it |
| Max 6 lines per slide | More than 6 lines = wall of text |
| Max 8 words per line | Audience reads, not listens, if text is long |
| Sentence fragments, not sentences | "Improves F1 by 3.2%" not "Our method improves the F1 score by 3.2 percentage points" |
| Figure slides: figure ≥60% area | The figure IS the content; bullets are annotations |
| Bold key numbers | "Achieves 94.3% accuracy" |
| Progressive disclosure | Use \pause or \onslide for complex slides |
| No Related Work slide | Unless invited talk (30+ min) |

Review this [TALK_TYPE] presentation ([TALK_MINUTES] min) for [VENUE].
Evaluate using these criteria (score 1-5 each):
1. **Story arc** — Does the talk build a compelling narrative? (Problem → insight → method → evidence → takeaway)
2. **Slide density** — Any slides with too much text? (Max 6 lines, 8 words/line)
3. **Time budget** — Is [N] slides realistic for [TALK_MINUTES] minutes?
4. **Figure visibility** — Will figures be readable on a projector?
5. **Opening hook** — Do slides 2-3 grab attention? (Not "In this paper, we...")
6. **Takeaway** — Is the final message clear and memorable?
7. **Progressive build** — Are complex ideas revealed gradually?
