0.6.0 (2026-10-01)

Adds image/text layouts, four native editable chart types, selected-page edits and undo, page-specific quality reports, four scenario outlines and shared branding. Optional official LibreOffice Kit rendering reads the final PPTX to produce PNG/PDF with font diagnostics. Fixes overlapping overview thumbnails, undersized table titles, image-caption spacing and chart labels.

The goal remains a usable finished deck. The agent prepares actual facts and content; the deterministic generator does not research or invent missing facts. Template-only output is explicitly an unfilled draft and must not be delivered as a finished presentation.

Default PPTX fonts use platform fallbacks and explicit East Asian families separately from HTML's CSS font stacks. Replace missing fonts, regenerate and review the pages; unresolved font problems must be disclosed instead of claiming acceptance.

Validation: Windows / Node 24.16.0, 100 passing tests; 18 components mount together on official-source Harness 0.2.0-rc.2 (639ed01539) with 104 tools and 35 skills. Fifteen default-theme pages without brand overrides passed native PNG/PDF rendering and individual visual review; an eleven-page image/chart/brand sample was checked in the browser, Microsoft PowerPoint and the official Kit. This covers those samples, not automatic acceptance of arbitrary decks.

0.5.0 update (2026-09-27)

Includes presenter previews, thumbnails and timer controls. Unsupported or rejected fullscreen requests now show an actionable message instead of silently failing.

Validation host: Harness 0.2.0-rc.1 built from official sources (commit 407e65c8) with Node 24.16.0 on 2026-09-28. All 70 plugin tests pass in an isolated environment; all 18 plugins mount together in one host registering 1 skills and 2 tools, with tool schemas and health-check contracts passing. No live ports or external services were exercised in this round.

One sentence or one document → a complete presentation: HTML web slideshow + PPTX export, 5 visual themes, slide transitions + bullet entrance animations, bilingual Chinese/English.

DeepSeek Harness (DSH) presentation skill and tools: the agent prepares content, then generates an offline HTML slideshow, editable PPTX and JSON project. Images/charts use exact-version @office-kit/pptx@0.21.0; the shared Node generator supports Windows/macOS/Linux.

Capabilities

Capability	Description
ppt_create tool	Markdown / structured slides → *.html + *.pptx + *.json
ppt_themes tool	Lists the 5 built-in themes and their best use cases; pass preview: true with outputDir to write a side-by-side gallery plus one SVG palette card per theme
11 layouts	cover / section / bullets / statement / quote / table / closing / image / image-left / image-right / chart
Speaker notes	<!-- note: ... --> comments or the notes field: press S in the HTML player; native PPTX notes slides (presenter view)
Motion	On by default: HTML slide-in transitions + staggered bullet entrances; native PPTX fade transitions + click-to-reveal bullets. motion: 'off' / --motion off for a fully static deck
Markdown extras	Tables (| ... |), blockquotes (>), and note comments are auto-detected into matching layouts
dsh-ppt skill	A complete six-step SOP registered into DSH
Standalone SKILL.md	Copy skills/dsh-ppt/ into Claude Code / Cursor / Gemini CLI / Codex for cross-harness use
Visual engine	Reuses the hyperframes visual style library; HTML and PPTX share the same theme source

Example:

Turn this sentence into a deck: "AI support cuts first response time to 8 seconds", with a dark tech theme.

Turn docs/quarterly-review.md into a bilingual presentation and export PPTX.

Compatibility

Plugin and standalone skill require Node ^22.19.0 || >=24.0.0. No API key or mandatory configuration. The optional renderer is loaded on demand and its absence does not prevent startup or ordinary creation. Windows samples have been exercised in the browser, opened/exported in Microsoft PowerPoint, and rendered using the official Kit; review the actual pages for each new deck.

Installation

dsh plugin --profile web add dsh-ppt

On desktop, install dsh-ppt through plugin management. Restart the host after updating to load seven tools and the skill. Ask naturally to include screenshots/charts, edit only slide three, or undo the last edit; users do not need to write JSON.

Uninstall

dsh plugin --profile web remove dsh-ppt

Then restart the web service. To clean up fully, also remove the plugin entry from your profile cordis.patch.yml if you overrode it.

Quick start

Inside DSH (recommended)

1. ppt_themes { preview: true, outputDir: "dist" }   # themes + gallery
2. ppt_create {
     title: "Fewer Meetings",
     content: "# Problem\n- Too many meetings\n\n# Solution\n- Async decisions",
     theme: "data",
     lang: "en"
   }
3. Open the returned HTML path in a browser; edit the PPTX in PowerPoint / WPS / Keynote

Any harness (standalone SKILL.md)

Copy skills/dsh-ppt/ to any Agent Skills directory, then:

node <skill-dir>/scripts/build-deck.mjs \
  --title "Product Launch" \
  --content deck.md \
  --theme data \
  --lang en \
  --out dist/deck

Artifacts:

Existing artifacts are not overwritten by default: if any member of the trio already exists, the whole set receives a shared -1, -2, ... suffix. Replacement requires explicit overwrite: true (or --overwrite in the CLI).

File	Purpose
*.html	Standalone slideshow: arrow keys, V presenter view (separate window with real current/next previews, thumbnail strip, notes, timer, progress, pause, font size, blank screen), S notes, G thumbnail overview, F fullscreen, P print, ? shortcuts, Esc close
*.pptx	Editable 16:9 presentation (hand-written OOXML, zip via node:zlib, no third-party deps)
*.json	Structured manifest (version, theme, language, slides)

Images, charts, editing and review

The additional tools are ppt_templates, ppt_edit, ppt_undo, ppt_check, and ppt_render. New layouts are image, image-left, image-right and chart, alongside the seven existing layouts.

An image slide accepts image: {src, alt, fit: "contain"|"cover", caption}. Use local PNG/JPEG paths relative to session cwd or matching data URIs. Assets are embedded in all outputs and undo works after original files move. Limits: 5 MiB / 32 megapixels per image, 32 MiB total project assets. Remote links and SVG are not automatically downloaded or converted.

A chart accepts chart: {kind:"column"|"bar"|"line"|"pie", categories, series:[{name,values}], unit, caption} or rows with a category/series header. Values must be finite with matching lengths. Pie requires one nonnegative series with a positive total. HTML uses accessible SVG and data tables; PPTX contains native charts and embedded editable workbooks.

brand supports name, primaryColor, backgroundColor, textColor, fontFamily, logo and footer. Colors are #RRGGBB; select a font available on the recipient computer. template is weekly|defense|project|pitch and does not overwrite a supplied narrative.

Edit example: {deckPath:"report.json",expectedRevision:0,edits:[{slide:3,patch:{title:"A clearer conclusion",bullets:["Evidence","Next action"]}}]}. Use ppt_check to obtain stable IDs and the revision; ppt_undo restores the latest edit including assets/brand. Keeps up to 20 edits and rejects stale revisions. The artifact trio is regenerated atomically with rollback on commit failure.

deliveryStatus: draft means unfilled slots; ready-for-review means review can start. Static estimates, rendering and visual inspection are recorded separately. Generation/rendering never automatically certifies visual quality. Inspect HTML and every page image before delivery.

Optional PNG/PDF renderer

Install in the plugin's project or standalone skill directory:

npm install --ignore-scripts @deepseek-ai/libreoffice-kit@0.1.3

The exact optional peer is not a mandatory engine download for ordinary consumers. Windows also needs the Microsoft Visual C++ v14 runtime matching Node's architecture. Missing dependency/engine returns unavailable with guidance.

ppt_render {pptxPath:"report.pptx",format:"both"} reads the final PPTX without resaving it and returns page PNGs, PDF and receiptPath. Pass that path as renderReceipt to ppt_check to recheck the current PPTX and every output's digest. Editing the source or outputs invalidates the receipt. Static artifacts do not retain animation. LibreOffice/PowerPoint/WPS may lay out files differently; font diagnostics do not guarantee every glyph or install fonts. See integration details.

CLI supports --slides @slides.json, --brand @brand.json, --template weekly, --edit report.json --edits @edits.json --revision 0, --undo report.json --revision 1, --check report.json, and --render report.pptx --format both. Explicit receipt validation uses --check report.json --render-receipt path/to/render-receipt.json; failure returns a nonzero exit code.

For standalone usage copy the entire skill directory and run npm install --ignore-scripts there. Plain text remains usable without Office Kit; image/chart/logo/footer PPTX export needs Office Kit 0.21.0. dsh-ppt/deck-advanced exports buildDeckAsync, editDeck, undoDeck, checkDeckAsync and renderDeck. The legacy synchronous deck-core API supports plain text and explicitly rejects unsupported media inputs.

Theme palette

ID	Name	Mood	Best for
data	Data Drift (default)	Futuristic / immersive	AI, tech launches, research
swiss	Swiss Pulse	Precise / rational	Data, SaaS, developer tools
velvet	Velvet Standard	Premium / restrained	Executive decks, brand, investor pitches
soft	Soft Signal	Warm / human	Brand stories, training, personal talks
bold	Maximalist Type	Loud / kinetic	Product launches, events, big moments

Themes are derived from dsh-hyperframes visual-styles.md. Full palettes: skills/dsh-ppt/references/themes.md. Run ppt_themes { preview: true, outputDir: "dist" } for a side-by-side gallery and SVG palette cards.

Markdown input rules

• The first # heading becomes the cover title; its first paragraph becomes the cover subtitle.
• Each ## section becomes one slide: lists produce bullets slides; empty sections produce section dividers.
• Plain text without headings: the first paragraph is the cover, then every 5 sentences become one slide.
• A single sentence automatically produces a complete 3-slide structure: cover → core idea → closing.
• Long tables paginate automatically with repeated headers and up to 8 data rows per page. Notes stay on the first page. Tables support 8 columns and 60 characters per cell; oversized input returns an actionable error. Short rows are padded consistently in all artifacts.
• maxSlides counts pages after expansion. Exceeding it fails before writing files; raise the limit (up to 120) or split the deck. Middle slides are never silently discarded.
• For precise control, use structured slides (cover | section | bullets | statement | quote | table | closing), with rows for tables and notes for speaker notes.

Configuration

No required configuration. Optional:

- id: dsh-ppt
  config:
    outputDir: E:\decks   # optional; defaults to the session working directory
    maxSlides: 40         # optional; default 60 (3–120)
    defaultTheme: data    # optional; used when ppt_create has no theme
    defaultLang: en       # optional; used when ppt_create has no lang (zh/en/bilingual)

The DSH_PPT_OUTPUT_DIR env var can also set the default output directory; the ppt_create outputDir/theme/lang arguments have the highest priority.

Relative paths and configured output directories resolve per session cwd without changing process cwd. Cancellation is checked during generation and before atomic commit of the trio. Optional rendering defaults to a unique <deck>-render directory beside the PPTX.

Bilingual support

• lang argument: zh (default) / en / bilingual controls the player UI, page numbers, and closing defaults.
• Content language is up to the author: for a bilingual deck, prefer "Chinese title + English subtitle" or generate two decks from the same outline.
• Plugin docs come in Chinese (README.md) and English (this file); CLI and skill error messages are in Chinese.

Engineering quality

• Tools and the skill share an asynchronous generator. The legacy synchronous plain-text API remains available.
• Images and native charts use MIT-licensed @office-kit/pptx@0.21.0; optional rendering is loaded on demand.
• Unit tests cover registration contracts, JSON Schema, theme resolution, Markdown parsing, artifact generation, PPTX part integrity, and the CLI.
• No eval / child_process / secrets; artifacts are only written to the user-specified local directory.

Development

pnpm install
pnpm run build      # tsc → lib/
pnpm test           # build + node --test (registration/config/engine/CLI)
pnpm run smoke:cli  # bare CLI smoke test, generates .smoke-deck

Known limitations

• The PPTX uses a blank layout plus text boxes: text is editable in PowerPoint / WPS, but no smart master placeholders yet.
• A one-sentence input produces a minimal 3-slide structure; for richer decks, expand the content into a Markdown outline first.
• bilingual only localizes the player UI; it does not translate content.
• Selected-page editing supports this plugin's JSON project, not arbitrary external PPTX editing.
• Text fit checks are static estimates; inspect actual rendered output for clipping and font substitution.
