Paper Slides: From Paper to Conference Talk

Generate conference presentation slides from: **$ARGUMENTS**

Context

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*.

Constants

• **VENUE = `NeurIPS`** — Target venue, determines color scheme. Supported: `NeurIPS`, `ICML`, `ICLR`, `AAAI`, `ACL`, `EMNLP`, `CVPR`, `ECCV`, `GENERIC`. Override via argument.
• **TALK_TYPE = `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.
• **TALK_MINUTES = 15** — Talk duration in minutes. Auto-adjusts slide count (~1 slide/minute for oral, ~1.5 slides/minute for spotlight). Override explicitly if needed.
• **ASPECT_RATIO = `16:9`** — Slide aspect ratio. Options: `16:9` (default, modern projectors), `4:3` (legacy).
• **SPEAKER_NOTES = true** — Generate `\note{}` blocks in beamer and corresponding PPTX notes. Set `false` for clean slides without notes.
• **PAPER_DIR = `paper/`** — Directory containing the compiled paper.
• **OUTPUT_DIR = `slides/`** — Output directory for all slide files.
• **REVIEWER_MODEL = `gpt-6-astra`** — Model used via Codex MCP for slide review.
• **AUTO_PROCEED = false** — At each checkpoint, **always wait for explicit user confirmation**.
• **COMPILER = `latexmk`** — LaTeX build tool.
• **ENGINE = `pdflatex`** — LaTeX engine. Use `xelatex` for CJK text.

Optional: Style reference (`— style-ref: <source>`, opt-in)

Lets the user steer the talk's **structural** rhythm (story beats, theorem density, figure density inherited from the source paper) toward a reference paper. **Default OFF — when the user does not pass `— style-ref`, do nothing differently from before.**

Only when `— style-ref: <source>` appears in `$ARGUMENTS`, run the helper FIRST:

# Resolve $STYLE_HELPER via the canonical strict-safe chain (see
# shared-references/integration-contract.md §2). Policy A — gate:
# unresolved helper means --style-ref cannot be satisfied, so abort.

Sources accepted: local TeX dir / file, local PDF, arXiv id, http(s) URL. Overleaf URLs/IDs are rejected — clone via `/overleaf-sync setup <id>` first and pass the local clone path.

**Strict rules** (full contract in `tools/extract_paper_style.py` docstring):

• Use `style_profile.md` to align section-budget tendency and theorem-environment density. Talk-type slide count above still takes precedence.
• **Never copy speaker-note prose, slide titles, or examples** from anything reachable through the cache. The talk content is from the user's paper, not the reference.
• **Never pass `— style-ref` (or the cache contents) to the GPT-6-Astra reviewer sub-agent** — the reviewer must judge the talk's clarity on its own merits.

Talk Type → Slide Count

| 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 |

Venue Color Schemes

Same as `/paper-poster-html`:

| Venue | Primary | Accent | Background | Text | |-------|---------|--------|------------|------| | NeurIPS | `#8B5CF6` | `#2563EB` | `#FFFFFF` | `#1E1E1E` | | ICML | `#DC2626` | `#1D4ED8` | `#FFFFFF` | `#1E1E1E` |
