Paper Talk: End-to-End Conference Talk Pipeline

Workflow: from a completed paper to a conference-ready talk artifact — slide outline, Beamer source, editable PPTX, speaker notes, full talk script, polished visuals, and assurance checks.

Pipeline target: $ARGUMENTS

Assurance Ladder

The skill takes an explicit — assurance: argument; default is polished.

| Level | Phases run | Use when | |---|---|---| | draft | 0 → 1 → 2 → 5 → 6 | Internal practice talk; quick first-pass deck | | polished (default) | 0 → 1 → 2 → 3 → 5 → 6 | Lab seminar, workshop, default conference talk | | conference-ready (or submission) | 0 → 1 → 2 → 3 → 4 → 5 → 6 | Top-venue oral / spotlight where slide claims are scrutinised; or anonymous submission |

Phase 4 (assurance checks) is opt-in via — assurance: conference-ready. The lower levels skip claim / citation / anonymity audits, which is correct when content has already been audited at the paper-writing stage.

Hard Invariants

These are non-negotiable across all phases:

1. Original paper is read-only. This workflow consumes the paper directory; it never modifies paper/main.tex or other paper artifacts.
2. Original deck is preserved. /paper-slides produces a baseline deck; /slides-polish writes a _polished versioned copy. The original Beamer + PPTX are never overwritten.
3. Speaker notes are byte-stable. Polish must not change slide.notes_slide content. Phase 4 verifies this.
4. No new content anywhere in the pipeline. All slide text, speaker notes, talk script, Q&A answers, claims, numbers, citations, URLs, author names, affiliations, anonymity placeholders, and experiment results must be either paper-grounded (extracted from PAPER_DIR/ artefacts) or explicitly user-provided. The pipeline never invents content during outline, build, polish, audit, or export. Phase-4 anonymity scan + claim audit verify this end-to-end.
5. No slide reordering. Add / drop / reorder requires explicit user flags.
6. Cross-model independence. Per-page Codex calls in /slides-polish use fresh threads (no codex-reply). See ../shared-references/reviewer-independence.md.
7. Anonymity fail-closed. If any audit (or any Codex fix proposal) would replace a placeholder with a real title / count / URL, the workflow halts and surfaces the proposal for human review. See ../shared-references/experiment-integrity.md.
8. Style references are guidance, not text source. A — reference: PDF or — style: preset informs visual weight and structural rhythm; never copy prose, examples, slide titles, or speaker-note text from the reference.
9. Final report cannot be conference-ready unless required audits pass. Phase 6 verifies and downgrades verdict if audits fail.
10. reasoning_effort: xhigh is invariant across all effort levels for any Codex call invoked by sub-skills.

Constants

• PAPER_DIR = paper/ — Source paper directory. Override via positional argument.
• OUTPUT_DIR = slides/ — Where the deck artefacts live.
• STATE_DIR = .aris/paper-talk/ — Workflow state, audit logs, final report.
• TALK_TYPE = spotlight — Default talk format. Inherited by /paper-slides.
• TALK_MINUTES = 15 — Default duration. Inherited by /paper-slides.
• VENUE = NeurIPS — Default venue (used by /paper-slides color schemes when — style is not passed).
• ASPECT_RATIO = 16:9 — Inherited by /paper-slides.
• STYLE_PRESET — generic if not passed; why-rf and venue presets supported by /slides-polish.
• REFERENCE_VISUAL — Required when assurance ≥ polished. The Beamer compile of this talk is an acceptable self-reference; an external academic talk PDF is preferred when the user wants visual alignment beyond defaults.
• AUTO_PROCEED = false — Each major phase pauses for user approval. Set true only when explicitly requested.

Inputs

Discovered from $ARGUMENTS and the project directory:

1. PAPER_DIR/ — compiled paper (main.tex + main.pdf). The paper must already be in good shape; this workflow does not write the paper.
2. PAPER_DIR/sections/*.tex — section sources for content extraction.
3. PAPER_DIR/figures/ — figures available for slide reuse.
4. (optional) slides/SLIDE_OUTLINE.md — pre-existing outline (resume mode); skips Phase 1 generation.
5. (optional) — reference: <pdf> — visual anchor for /slides-polish. If absent and the assurance level requires polish, the workflow uses the Beamer self-compile as reference.
6. (optional) — talk_type, — minutes, — style, — effort — see Constants.

Output Layout

File names match /paper-slides's emit contract — this workflow is a non-renaming consumer.

Workflow

Phase 0: Setup

1. Validate paper directory: ls $PAPER_DIR/main.tex $PAPER_DIR/main.pdf. If absent → halt and ask user to point to the compiled paper.
2. Check prerequisites:
   • LaTeX: which xelatex pdflatex latexmk
   • PPTX rendering: which soffice (LibreOffice headless) — required for Phase 4 export integrity check; otherwise prompt user to export PDF manually.
   • PDF tools: which pdfinfo pdftoppm (poppler) — required for /slides-polish PNG rendering.
   • Codex MCP availability.
   • python-pptx (python3 -c 'import pptx').
3. Resolve overrides from $ARGUMENTS: talk_type, minutes, assurance, reference, style, effort.
4. State init: write .aris/paper-talk/PIPELINE_STATE.json with phase: 0, timestamp, all resolved overrides.
5. Resume mode: if slides/SLIDE_OUTLINE.md exists and PIPELINE_STATE.json shows recent in-progress work, prompt the user — resume from last phase or start fresh.

Phase 1: Slide Outline (Checkpoint)

Goal: produce or accept a slides/SLIDE_OUTLINE.md that the user signs off on before any deck-building happens.

If slides/SLIDE_OUTLINE.md already exists, present its summary (slide count, time budget, claim-per-slide map) to the user and ask:

"Use existing outline (Y/n)? Modify? Regenerate?"

Otherwise, delegate to /paper-slides Phase-1 only (content extraction + slide outline generation). /paper-slides writes the outline into its own state; we adopt it as slides/SLIDE_OUTLINE.md.

The outline must contain, per slide:

• A claim-first title (states the slide's point, not the topic).
• One main idea per slide.
• Bullet content (sentence fragments, not paragraphs).
• Figure / equation / callout note.
• Time budget (seconds).
• Transition cue.
• Speaker note seed (1-3 sentences; expanded in Phase 2).

Checkpoint: present the outline. Default behavior: pause for user approval. Set AUTO_PROCEED = true only when the user is explicitly running unattended.

Phase 2: Build Baseline Deck

Invoke /paper-slides to generate Beamer source + PPTX from the approved outline.

/paper-slides "<paper-dir>" — talk_type: <T> — minutes: <N> — venue: <V> — aspect: 16:9 — notes: true

Forward — style-ref: if the user originally passed it (writer-side; the reviewer-side polish in Phase 3 must NOT see it — see invariant 8).

/paper-slides produces (emit names fixed by /paper-slides):

• slides/main.tex + slides/main.pdf (Beamer)
• slides/presentation.pptx (editable PPTX)
• slides/speaker_notes.md
• slides/TALK_SCRIPT.md

After return: verify the four artefacts exist. If any missing, halt with a diagnostic. Do not rename outputs — downstream phases bind to these exact paths.

Phase 3: Visual Polish (when assurance ≥ polished)

Skip when assurance == draft.

Invoke /slides-polish against the freshly generated PPTX, with a reference. If the user passed — reference:, use that. Otherwise, use the Beamer compile (slides/main.pdf) as the visual reference — the Beamer is the design intent for the same talk, so it is the correct anchor when no external reference is available.

/slides-polish "slides/presentation.pptx" — reference: slides/main.pdf — style: <preset> — effort: <effort>

After return: verify slides/presentation_polished.pptx exists; if rendering tools are available, also verify slides/presentation_polished.pdf.

The polish phase is read-only on content (see Hard Invariants). If /slides-polish emits a BLOCKED verdict because a Codex fix proposal would alter content, surface that block to the user and halt rather than overriding.

Phase 4: Assurance Checks (when assurance == conference-ready)

Skip when assurance ∈ {draft, polished}.

/paper-claim-audit and /citation-audit expect a paper-shaped input (paper/main.tex + paper/sections/*.tex + paper/results/) and emit JSON under paper/. Slides have a different shape, so this phase first stages slide artefacts into a synthetic
