Academic PPTX Skill

Generate and edit academic/research PPTX presentations with native editable DrawingML shapes.

Core Capabilities

1. Create from scratch: Source content → SVG pages → DrawingML shapes → editable PPTX
2. Edit existing PPTX: Unpack → edit XML → validate → repack
3. HTML/JSX authoring path: Use HTML/JSX as an experimental upstream authoring layer, then normalize into EasySlides-compatible SVG or shape IR before the existing DrawingML backend
4. Academic scenario/template system: Scenario-first academic planning with template-extensible output. The current active layout packs are academic_general, academic_scqa, defense_leftnav, defense_topnav, and literature_minimal; they are inventory, not scope limits.
5. 71 visualization templates: Charts, infographics, diagrams, strategic frameworks, and tables
6. 11,634 icons: Six SVG icon families for consistent academic and business visuals, with lucide preferred for new generic icons and emoji replacement
7. Template Asset Bank: Convert many real PPTX templates into exact-reuse slide modules for manual-template-substitution quality

Backend-Centered Architecture

EasySlides has one production backend: normalized SVG/shape IR converted to editable DrawingML/PPTX by the local scripts/svg_to_pptx/ pipeline. Multiple authoring frontends may feed that backend, but do not introduce a second production PPTX backend unless a dedicated spike proves better editable output, Office compatibility, and lower maintenance cost.

Path A: Create from Scratch (SVG → DrawingML → PPTX)

When no template PPTX exists, use the SVG-to-DrawingML pipeline:

Source Content → Project Init → Strategist (Deck Plan + Design Spec) → SVG Generation → Quality Check → Export PPTX

Key advantage: Every SVG element becomes an editable DrawingML shape — text is selectable, colors are changeable, shapes are movable.

Path B: Edit Existing PPTX (XML Unpack/Edit/Repack)

When a template PPTX exists:

Template PPTX → Unpack XML → Edit Content → Clean Orphans → Validate → Repack PPTX

Key advantage: Preserves all template formatting, animations, and layout structure.

Path C: HTML/JSX Authoring (Experimental Upstream)

When the source is a rendered HTML page, dashboard, report, or SVG-heavy technical slide, use HTML/JSX only as an authoring and measurement layer:

HTML/JSX source -> browser measurement / component declarations -> normalized SVG or shape IR -> EasySlides validation -> DrawingML export

Key advantage: HTML/JSX is easier for LLMs to author for complex layouts, component reuse, dashboards, and architecture diagrams. The output still flows through the EasySlides checker and DrawingML backend.

Boundary: @artifact-kit/pptxgenjs-jsx and html-to-pptx-skill may be used as references or in isolated spikes, but they are not main-path dependencies of EasySlides. Prefer integrating their DOM measurement and JSX authoring ideas upstream of the existing SVG/DrawingML backend.

Use workflows/html-jsx-authoring.md when evaluating this path.

For a large library of PPTX templates, prefer the Template Asset Bank harness:

PPTX templates → pptx_template_import.py workspaces → template_asset_bank.json → exact slide-module reuse

Use workflows/template-asset-bank.md and scripts/template_asset_bank.py when the goal is to mimic manual template substitution: fixed geometry, fixed decorative structure, and only text/image/chart data replaced.

---

Academic Scenario-First Template Contract

Use scenario first, template second for academic work. In plain terms: scenario first, template second. The academic scenario defines the argument structure, evidence obligations, audience state, and page roles; the template route defines visual containers, geometry, palette, chrome, and reusable slide modules.

• A template route is not a scenario: template route is not a scenario. Do not infer "thesis defense" just because a defense-looking template is selected, and do not infer "literature report" just because a literature-style shell is available.
• The built-in scenario ids are seed profiles for routing, not a closed taxonomy. If the user's academic use case is not an exact match, select the nearest profile and record scenario_variant in deck_plan.json and design_spec.md.
• Preserve the selected profile's hard and required rules, then explicitly note which recommended or relaxable rules change for the scenario_variant.
• When no matching visual template exists, do not force a defense or literature-report template. Use free academic design, a general academic pack, a domain pack, or a user-provided template path while keeping source traceability, citation retention, text fit, and PPTX deliverability intact.
• When academic_general or academic_scqa is selected, read references/academic-orchestration.md and apply Audience-State-Transfer plus SCQA before selecting layouts. These templates are for audience-facing academic orchestration, not developer-facing production notes.

Source Material Policy

Before planning or generating a deck, classify the user's input:

• No supplied source materials: if the user gives only a topic, requirements, or a request to research before making the PPT, run workflows/topic-research.md. You may gather web text and download relevant openly licensed images as PPT assets, then import the research document and image folder as source materials with provenance.
• Provided mature source materials: if the user supplies a journal paper, thesis/dissertation, mature report, existing deck, or similar file/URL with substantive text, figures, tables, or captions, treat that material as the source of truth. Build from its claims, structure, figures, tables, captions, and user-provided assets. Do not replace extracted figures, invent substitute evidence visuals, change the source claims, or add outside material unless the user explicitly asks; any added generic background/icon must remain decorative and never stand in for source evidence.

Path A: Create from Scratch

Step 1: Requirements & Project Init

python scripts/project_manager.py init <project_name> --format ppt169
python scripts/project_manager.py import-sources <path> <files...> --move

Supported source formats: PDF, DOCX, XLSX, PPTX, URL, Markdown.

MinerU PDF Preprocessing: When importing PDFs, the system automatically tries MinerU for structural extraction before falling back to PyMuPDF. MinerU provides richer output: Markdown with figure/table identification, layout JSON, and extracted images — enabling better PPTX generation with automatic figure extraction.

Method	Token Required	Output	Limits
Precision Extract API	Yes (MINERU_API_TOKEN env or .mineru_token file)	Markdown + JSON + images	≤200 MB, ≤600 pages
Agent Lightweight API	No (IP-rate limited)	Markdown only	≤10 MB, ≤20 pages
PyMuPDF fallback	No	Text + images (heuristic)	None

To enable MinerU: set MINERU_API_TOKEN environment variable or create a .mineru_token file in the project root.

Paper-Report Intake

For single-paper report decks, run the paper-report intake after importing sources and before Strategist writes the final deck plan:

python scripts/paper_intake.py <project_path> --json

The intake reads <project_path>/sources/, Markdown converted from the PDF, MinerU/PyMuPDF-side manifests when present, and <project_path>/images/. It drafts deck_plan.json with a source_map for the main paper plus extracted figures, then validates the draft with scripts/deck_plan_contract.py. Strategist should treat the output as a traceable starting point: verify the paper title, figure captions, claims, and slide roles before writing the final design_spec.md and spec_lock.md.

Single-Paper Literature-Report Flow Selection

Before deriving the outline for single_paper_report, read references/literature-report-flow-selection.md.

If the user provides a page outline, speaking script, learning notes, or slide-by-slide plan, that structure is the primary story contract. Preserve the user's page order and speaking logic, then use the paper/SI to verify claims and source figures. Do not replace the user's structure with an automatic long-form literature-report flow unless the user explicitly asks for a rebuild.

If no outline or script is provided, choose or present two flow options:

• paper_ppt_concise: concise, figure-first 6-10 slide paper report inspired by xiao634zhang/paper-ppt-skill.
• literature_report_deep_dive: 20+ slide deep literature-report planning flow inspired by fangyuanopus/literature-report-ppt-builder, with figure_source_manifest, deck_order_map, and page_briefs before visual execution.

Both options still use EasySlides' editable SVG/shape-IR -> DrawingML backend as the production path.

Scenario Profiles and Rule Layers

Before the confirmation step for academic decks, load the scenario profile catalog from references/scenario_profiles.json.

python scripts/scenario_profiles.py --list --json
python scripts/scenario_profiles.py --profile <profile_id> --json

Seed academic profiles are single_paper_report, multi_paper_review, thesis_defense, proposal_or_fund, lab_progress, workshop_training, and conference_talk. Pick the nearest profile from the source material, audience, and occasion, then state it as a recommendation during confirmations. If the deck is an academic scenario outside these seeds, keep the nearest profile as the rule base and record a scenario_variant rather than squeezing the deck into defense or literature-report wording.

Apply rule layers in this order:

• hard_rules: always enforce; source faithfulness, traceability, citations, text fit, template geometry integrity, and PPTX deliverability.
• required_rules: enforce for the selected scenario unless the user changes the scenario.
• recommended_rules: default guidance such as action titles or ghost-deck checks; apply when useful, but let templates and content needs override.
• relaxable_rules: soft defaults that can yield to venue, template, or teaching/activity format.

Templates control visual containers; scenario profiles control content organization. Template colors, title treatment, page chrome, icon style, and layout density may override profile recommendations only when allowed by template_may_override; they must not override protected items in template_must_not_override.

Deck Plan Contract

After confirmations and before spec_lock.md, write deck_plan.json as the page-level academic story contract:

python scripts/deck_plan_contract.py <project_path>/deck_plan.json --json

Each slide entry must include page, role, action_title, claim, evidence_sources, layout_id, rhythm, and speaker_note. Use action_title for the page's conclusion sentence, claim for the supported statement, and evidence_sources for source-map references such as paper pages, figure/table ids, extracted images, datasets, or user-provided assets. The validated deck plan feeds design_spec.md, spec_lock.md page_rhythm, and later QA gates.

When the selected template exposes a LOGO slot, resolve it from user-provided assets and source-material image folders before SVG generation. Prefer an actual institutional, laboratory, project, or paper-source logo. If no suitable logo is available, keep the template's built-in degree-cap icon fallback; when a real logo is inserted, replace the full LOGO group or hide the fallback drawing.

Academic QA Gate

Before SVG generation, run the Academic QA Gate on the finalized deck_plan.json:

python scripts/academic_qa_gate.py <project_path>/deck_plan.json --json

The gate checks the deck-plan contract plus academic expression rules: action_title must be a conclusion sentence rather than a topic label, result pages need figure/table/data/chart evidence, source-linked decks should include a References/source-provenance slide, and scenarios that recommend conclusion_last should end on Conclusions rather than a generic thank-you page. Errors block execution; warnings should be resolved or consciously accepted before writing final SVGs.

For academic content, present the Five Confirmations (blocking):

#	Confirmation	Default for Academic
1	Canvas format	16:9 (1280x720)
2	Page count	Based on source volume
3	Target audience	Committee / peers / general
4	Style objective	Mode B (data clarity) or C (logical persuasion)
5	Color scheme	Academic blue #003366 + accent #0066CC

After user confirms, output deck_plan.json, design_spec.md, and spec_lock.md.

Step 2: Template and Design Foundation

Choose the design foundation from the confirmed scenario and template route:

• If the user provides an explicit template path, inspect that template and bind the story roles to its available shells or reusable modules.
• If the user asks to use an available EasySlides template, select the best matching active academic pack from templates/layouts/.
• If no matching template exists, create a free academic design or use a general/domain academic pack; do not force a defense or literature-report template onto unrelated academic scenarios.
• academic_general is the neutral general academic fallback when no domain or scenario-specific pack fits.
• academic_scqa is the structured academic/technical report variant when the material benefits from visible Audience-State-Transfer and SCQA progression.

The design spec must record the chosen scenario_profile, any scenario_variant, the template route, and which template constraints may override visual preferences. Use templates/reference/design_spec_reference.md for the required 11-section structure, then pull the selected template's design_spec.md only if that template is actually selected.

Step 3: SVG Generation

Generate SVG pages sequentially (one at a time). In Path A, each page is hand-written SVG. In Path C, generated SVG must be normalized to the same contract before validation and export.

Critical rules:

• viewBox must match canvas (e.g., 0 0 1280 720)
• Use <rect> for backgrounds, <tspan> for text wrapping
• Never use rgba(), foreignObject, <mask>, or <script>
• Reference icons via <use data-icon="library/icon-name"/> (see templates/icons/README.md); for new generic icons and emoji replacement, prefer lucide/* and color it with the deck theme color
• Reference charts from templates/charts/ as SVG templates
• Re-read spec_lock.md before every page to prevent drift

SVG quality check:

python scripts/svg_quality_checker.py <project_dir>

Step 4: Post-processing & Export

# 1. Split speaker notes
python scripts/total_md_split.py <project_dir>

# 2. Finalize SVGs (embed icons, base64 images, flatten text)
python scripts/finalize_svg.py <project_dir>

# 3. Export to PPTX
python scripts/svg_to_pptx.py <project_dir>

Output: exports/<project_name>.pptx with native DrawingML shapes.

Step 5: PPTX Package & Render QA

After every export, run package validation and rendered preview checks before delivery:

python scripts/office/unpack.py <output.pptx> <tmp_unpacked>
python scripts/office/pack.py <tmp_unpacked> <tmp_roundtrip.pptx> --original <output.pptx> --validate true
python scripts/source_to_md/ppt_to_md.py <output.pptx> -o <project_dir>/reports/pptx_text_check.md

If speaker notes are enabled, package validation must prove that ppt/notesMasters/notesMaster1.xml exists, the presentation has a notes master relationship, and the deck has the expected notesSlide*.xml files. Missing notes master relationships are blocking even if slide previews look fine.

Render the final PPTX itself, not just the source SVGs. Use LibreOffice/soffice to export PDF and Poppler or PyMuPDF to render page PNGs. If soffice or pdftoppm is missing from PATH, locate the executable explicitly or use the PyMuPDF fallback; do not skip visual QA. Inspect full-size previews for dense cards, process pages, tables, references, and any text that was ported from a larger template. Contact sheets are useful for rhythm only and can hide one-line overflow.

Academic Page Layouts

When academic_general is selected as the neutral fallback, use these base layout patterns:

Layout	Use For	SVG Template
Cover	Title, author, institution	01_cover.svg
TOC	Outline with descriptions	02_toc.svg
Chapter	Section dividers (dark blue)	02_chapter.svg
Content	Main content pages	03_content.svg
Ending	Thank you / Q&A	04_ending.svg

Content page sub-layouts:

• Single column: Centered text for key points
• Two-column cards: Side-by-side comparison
• Left-right split (5:5 or 4:6): Text + image
• Card grid: Multiple items in grid
• Timeline: Process flow or chronological data
• Table: Structured data comparison

Academic Built-in Layout Library

Use templates/layouts/ when the user explicitly asks to use a template path or asks what academic templates are available. The directory contains 5 active academic layout packs: academic_general, academic_scqa, defense_leftnav, defense_topnav, and literature_minimal. Broader brand, government, enterprise, domain-specific, and special-style PPT Master packs are not part of the active library unless restored for a specific academic use case. This active inventory does not define the full academic scope; new or external templates may be bound to any academic scenario_variant if they preserve the hard rules.

Each classic pack contains design_spec.md and page shell SVGs such as 01_cover.svg, 02_toc.svg, 02_chapter.svg, 03_content.svg, and 04_ending.svg. If a future active pack uses a slot-guided mode, it should also carry layouts.json, page_catalog.json, rules.md, story_structure.json, and generated contract sidecars.

Discovery:

• Human overview: templates/layouts/README.md
• Slim index: templates/layouts/layouts_index.json
• Root template references: templates/reference/design_spec_reference.md and templates/reference/spec_lock_reference.md

Do not fuzzy-match a bare template name when following PPT Master's stricter template flow. Prefer an explicit directory path such as templates/layouts/academic_general/.

L001 Notebook Defense Style Pack

Use templates/style_packs/l001_notebook_defense/ when the user asks for the L001 notebook-defense / burgundy defense style. This is a minimal style pack, not a copy of the full EasyPPT asset registry.

Key files:

• design_tokens.json: locked wine-red palette, Microsoft YaHei typography, fixed closing title, and coordinate contracts.
• layouts.json: five lightweight page shells mapped to L001 source layouts.
• 01_cover.svg to 05_closing.svg: SVG templates for the EasySlides SVG-to-PPTX path.
• scripts/styles/l001.py: reusable SVG helper functions.

Validate after edits:

python scripts/validate_l001.py templates/style_packs/l001_notebook_defense
python scripts/svg_quality_checker.py templates/style_packs/l001_notebook_defense

Guizang PPT Editable Style Pack

Use templates/style_packs/guizang_ppt/ when the user asks for Guizang, electronic magazine, electronic ink, or Swiss internationalism styles while still needing editable PPTX output. This pack adapts https://github.com/op7418/guizang-ppt-skill from HTML/CSS deck templates into the EasySlides SVG-to-DrawingML path.

Key files:

• design_tokens.json: Style A's five ink/paper themes and Style B's four Swiss accent themes.
• layouts.json: Style A shell mapping plus the upstream Swiss S01-S22 layout registry mapped into editable shell families.
• style_a/01_cover.svg to style_a/04_closing.svg: Style A native SVG shells.
• style_b/01_cover.svg to style_b/05_closing.svg: Style B native SVG shells.
• swiss/S01_index_cover.svg to swiss/S22_image_hero.svg: one native SVG skeleton for each upstream Swiss locked layout.
• scripts/styles/guizang.py: reusable SVG helper functions.
• scripts/style_pack_contract.py: validates spec_lock.md style_pack declarations and resolves Guizang page_layouts IDs to concrete SVG files.

When using Guizang as a harness, write ## style_pack in spec_lock.md with package: guizang_ppt, the locked variant, theme, layout_source, and validator. Style B pages should prefer S01-S22 layout IDs when the content shape matches the upstream Swiss layout registry.

Validate after edits:

python scripts/style_pack_contract.py <project_path>/spec_lock.md --json
python scripts/validate_guizang.py templates/style_packs/guizang_ppt
python scripts/validate_guizang.py templates/style_packs/guizang_ppt --spec-lock <project_path>/spec_lock.md --json
python scripts/svg_quality_checker.py templates/style_packs/guizang_ppt

Chart Integration

Reference chart SVGs from templates/charts/. The catalog contains 71 templates. Common academic charts:

Chart Type	File	Use Case
Bar chart	bar_chart.svg	Comparisons
Line chart	line_chart.svg	Trends over time
Scatter	scatter_chart.svg	Correlations
Box plot	box_plot_chart.svg	Data distribution
Radar	radar_chart.svg	Multi-dimensional comparison
Heatmap	heatmap_chart.svg	Matrix data
Fishbone	fishbone_diagram.svg	Root cause analysis
Timeline	timeline.svg	Process / milestones

To use a chart: read the SVG template, replace placeholder data with actual data, and embed in the slide SVG.

Path B: Edit Existing PPTX

Step 1: Analyze Template

python scripts/thumbnail.py template.pptx
python -m markitdown template.pptx

Review thumbnails.jpg for layouts, markitdown output for placeholder text.

Step 2: Plan Slide Mapping

For each content section, choose a template slide.

Use varied layouts — monotonous presentations are a common failure mode. Don't default to title + bullet slides. Actively seek out:

• Multi-column layouts (2-column, 3-column)
• Image + text combinations
• Full-bleed images with text overlay
• Quote or callout slides
• Section dividers
• Stat/number callouts

Step 3: Unpack

python scripts/office/unpack.py template.pptx unpacked/

Extracts PPTX, pretty-prints XML, escapes smart quotes.

Step 4: Structural Changes (do sequentially, not with subagents)

• Delete unwanted slides: remove from <p:sldIdLst> in ppt/presentation.xml
• Duplicate slides: python scripts/add_slide.py unpacked/ slide2.xml
• Reorder: rearrange <p:sldId> elements
• Complete all structural changes before editing content

Step 5: Edit Content (parallelizable with subagents)

Each slide is a separate XML file (ppt/slides/slide{N}.xml). Use subagents for parallel editing.

Use the Edit tool, not sed or Python scripts.

Formatting rules:

• Bold headers: b="1" on <a:rPr>
• Never use unicode bullets — use <a:buChar> or <a:buAutoNum>
• Multi-item content: separate <a:p> elements, never concatenate

Step 6: Clean & Validate

python scripts/clean.py unpacked/
python scripts/office/pack.py unpacked/ output.pptx --original template.pptx

Design Quality Standards (from guizang-ppt-skill)

Layout Rhythm

• Alternate light/dark/hero pages — no 3+ consecutive same-theme pages
• Use varied layouts across the deck
• Maintain consistent spacing (card gap 20px, content block gap 24px)

Typography Hierarchy

Level	Size (1280x720)	Weight	Use
H1	56px	Bold	Cover title
H2	36px	Bold	Section headers
H3	28px	Bold	Subsection headers
Body	20px	Regular	Main content
Caption	16px	Regular	Labels, annotations
Footnote	12px	Regular	Page numbers, sources

Color Usage (60-30-10 Rule)

• 60%: Neutral backgrounds (#FFFFFF, #F5F7FA)
• 30%: Primary color (#003366)
• 10%: Accent color (#0066CC, #CC0000 for emphasis)

Icon Discipline

• Use one stylistic icon library per deck; prefer lucide for new generic icons and emoji replacement, with fill set to the deck theme color. simple-icons is only for brand marks.
• Reference via <use data-icon="library/icon-name"/>
• Icons are embedded during finalization — never use emoji

Common Pitfalls

SVG Generation

1. Wrong viewBox: Must match canvas dimensions exactly
2. Missing spec_lock re-read: Re-read before every page
3. Script-generated SVG: Forbidden — each page must be hand-written
4. Using rgba(): Use hex colors with opacity attributes instead
5. SVG <text> labels: Use HTML labels, not SVG text in diagrams
6. Template porting overflow: Compact templates such as defense_leftnav cannot safely reuse long card/process copy from larger templates. Shorten at the source content layer and use punctuation-aware Chinese wrapping before export.

PPTX Editing

1. Unicode bullets: Never use • — causes double bullets
2. Smart quotes: Use XML entities (“ etc.) in new text
3. Missing clean.py: Always run after structural changes
4. Manual slide copy: Use add_slide.py — manual copy misses bookkeeping
5. ElementTree: Use defusedxml.minidom — ElementTree corrupts namespaces
6. Unvalidated speaker notes: Notes slides require a notes master part, relationships, and content types. Always run the unpack/pack validation and a PPT-to-Markdown extraction check after exporting a deck with notes.

Design

1. Monotonous layouts: Vary layout types across the deck
2. Inconsistent spacing: Use the template's spacing system
3. Mixed icon styles: Stick to one library per deck
4. No visual rhythm: Alternate between light, dark, and hero pages
