AI-driven multi-format SVG content generation system. Converts source documents into high-quality SVG pages through multi-role collaboration and exports to PPTX.
Core Pipeline: Source Document → Create Project → [Template] → Strategist → [Image_Generator] → Executor Live Preview → Quality Check → Post-processing → Export
[!CAUTION]
🚨 Global Execution Discipline (MANDATORY)
This workflow is a strict serial pipeline. The following rules have the highest priority — violating any one of them constitutes execution failure:
- SERIAL EXECUTION — Steps MUST be executed in order; the output of each step is the input for the next. Non-BLOCKING adjacent steps may proceed continuously once prerequisites are met, without waiting for the user to say "continue"
- BLOCKING = HARD STOP — Steps marked ⛔ BLOCKING require a full stop; the AI MUST wait for an explicit user response before proceeding and MUST NOT make any decisions on behalf of the user
- NO CROSS-PHASE BUNDLING — Cross-phase bundling is FORBIDDEN. (Note: the Eight Confirmations in Step 4 are ⛔ BLOCKING — the AI MUST present recommendations and wait for explicit user confirmation before proceeding. Once the user confirms, all subsequent non-BLOCKING steps — design spec output, SVG generation, speaker notes, and post-processing — may proceed automatically without further user confirmation)
- GATE BEFORE ENTRY — Each Step has prerequisites (🚧 GATE) listed at the top; these MUST be verified before starting that Step
- NO SPECULATIVE EXECUTION — "Pre-preparing" content for subsequent Steps is FORBIDDEN (e.g., writing SVG code during the Strategist phase)
- NO SUB-AGENT SVG GENERATION — Executor Step 6 SVG generation is context-dependent and MUST be completed by the current main agent end-to-end. Delegating page SVG generation to sub-agents is FORBIDDEN
- SEQUENTIAL PAGE GENERATION ONLY — In Executor Step 6, after the global design context is confirmed, SVG pages MUST be generated sequentially page by page in one continuous pass. Grouped page batches (for example, 5 pages at a time) are FORBIDDEN
- SPEC_LOCK RE-READ PER PAGE — Before generating each SVG page, Executor MUST
read_file <project_path>/spec_lock.md. All colors / fonts / icons / images MUST come from this file — no values from memory or invented on the fly. Executor MUST also look up the current page'spage_rhythm(anchor/dense/breathing),page_layouts(which template SVG to inherit, if any), andpage_charts(which chart template to adapt, if any). Empty / absent entries are intentional Strategist signals — see executor-base.md §2.1. This rule exists to resist context-compression drift on long decks and to break the uniform "every page is a card grid" default- SVG MUST BE HAND-WRITTEN, NOT SCRIPT-GENERATED — Every SVG page is written by the main agent directly, one page at a time (see rules 6 and 7). Writing or running a Python / Node / shell script that produces the SVG files in batch — looping over pages, templating from data, or emitting them via a generator — is FORBIDDEN, including under "save tokens", "quick draft", or "user is in a hurry" pretexts. The script-generation path was tried on a feature branch and abandoned: cross-page visual consistency depends on per-page authoring with full upstream context, which a generator script cannot reproduce
[!IMPORTANT]
🌐 Language & Communication Rule
- Response language: match the user's input and source materials. Explicit user override (e.g., "请用英文回答") takes precedence.
- Template format:
design_spec.mdMUST follow its original English template structure (section headings, field names) regardless of conversation language. Content values may be in the user's language.

🚧 GATE: User has provided source material (PDF / DOCX / EPUB / URL / Markdown file / text description / conversation content — any form is acceptable).
No source content? When the user supplies only a topic name or requirements without any file or substantive description, run the
topic-researchworkflow first, then return here with its products as input.
When the user provides non-Markdown content, convert immediately:
| User Provides | Command |
|---|---|

Office vector assets (EMF/WMF) from DOCX/PPTX sources:
doc_to_md.py/ppt_to_md.pyextract embedded Office vector images (.emf/.wmf) alongside bitmap images. Afterimport-sources, these land inimages/together withimage_manifest.jsonand are first-class assets in §VIII Image Resource List.Do NOT convert EMF/WMF to PNG. The PPT Master pipeline preserves them as external references (
finalize_svg.pyskips them) andsvg_to_pptx.pyembeds them as PPTX-native media viaimage/x-emf/image/x-wmfMIME — PowerPoint renders them at full vector fidelity. Converting via LibreOffice/Inkscape introduces CJK font substitution drift and rasterization loss; the original EMF/WMF is always higher fidelity than the converted PNG.Browser-based live preview cannot render EMF (will show blank) — this is expected; the PPTX output is the source of truth.
✅ Checkpoint — Confirm source content is ready, proceed to Step 2.
🚧 GATE: Step 1 complete; source content is ready (Markdown file, user-provided text, or requirements described in conversation are all valid).
python3 ${SKILL_DIR}/scripts/project_manager.py init <project_name> --format <format>
Format options: ppt169 (default), ppt43, xhs, story, etc. For the full format list, see references/canvas-formats.md.
Import source content (choose based on the situation):
| Situation | Action |
|---|---|
| Has source files (PDF/MD/etc.) | python3 ${SKILL_DIR}/scripts/project_manager.py import-sources <project_path> <source_files...> --move |
| User provided text directly in conversation | No import needed — content is already in conversation context; subsequent steps can reference it directly |
⚠️ MUST use
--move(not copy): all source files — Step 1's generated Markdown, original PDFs / MDs / images — go intosources/viaimport-sources --move. After execution they no longer exist at the original location. Intermediate artifacts (e.g.,_files/) are handled automatically.
✅ Checkpoint — Confirm project structure created successfully, sources/ contains all source files, converted materials are ready. Proceed to Step 3.
🚧 GATE: Step 2 complete; project directory structure is ready.
Default — free design. Proceed directly to Step 4. Do NOT query any *_index.json unless triggered. Do NOT ask the user. Do NOT proactively suggest, hint at, or fuzzy-match any template based on content, slug-like words, or vague style descriptions.
Template flow triggers ONLY on explicit directory paths supplied by the user in their initial message. The trigger rule is mechanical, not interpretive:
| User input contains | Step 3 action |
|---|---|
One or more explicit template directory paths (each resolves to a directory containing design_spec.md with kind: brand / kind: layout / kind: deck in its YAML frontmatter) | Read each spec's kind, dispatch per the kind matrix below, fuse if multiple |
| Anything else — bare template names ("用 academic_defense"), style descriptions ("麦肯锡风格"), brand mentions ("招商银行风格"), vague intent ("想用个模板"), or silence | Skip Step 3, free design |
There is no slug matching, no name lookup, no fuzzy resolution. A name without a path does not trigger — the user must give a path the AI can cd into.
Style descriptions ("麦肯锡风格" / "Keynote 风" / "极简风" / etc.) never trigger Step 3. They flow into Strategist's Eight Confirmations as a style brief (color / typography / tone in confirmations e–g).
Bare names ("academic_defense", "招商银行", "anthropic") do NOT trigger Step 3 even if a matching directory exists in the library. The user must give a path. AI must not "helpfully" resolve a name to a path.
"What templates exist?" is out-of-band Q&A — answer by listing entries from
brands_index.json/layouts_index.json/decks_index.jsontogether with their paths. Listing alone does not advance the pipeline; the user must send a path back to trigger Step 3.
To create a new layout or deck, read
workflows/create-template.md. To create a new brand, readworkflows/create-brand.md.
The architecture has three independent reference bundles. Full schema in docs/zh/templates-architecture.md. Summary:
| Kind | Physical dir | Contains | Frontmatter |
|---|---|---|---|
| brand | templates/brands/<id>/ | identity-only segment: color / typography / logo / voice / icon style | kind: brand |
| layout | templates/layouts/<id>/ | structure-only segment: canvas / page structure / page types / SVG roster | kind: layout |
| deck | templates/decks/<id>/ | full replica: identity + structure + middle (template overview) segments | kind: deck |
Segment ownership (governs fusion override priority):
| Segment | Sections | Owner kind on fusion |
|---|---|---|
| Identity | Color Scheme / Typography / Logo / Voice & Tone / Icon Style | brand |
| Structure | Canvas / Page Structure / Page Types / SVG Roster | layout |
| Middle | Template Overview (use cases / design intent) | deck (no other kind writes this) |
User path's kind | Step 3 action |
|---|---|
kind: brand | Copy design_spec.md + logo files + asset subdirs (images/ / illustrations/ / icons/) into <project>/templates/. Strategist locks identity segment as truth; structure stays free. |
kind: layout | Copy design_spec.md + SVG roster + asset files into <project>/templates/. Strategist locks structure; identity decided in Eight Confirmations e–g. |
kind: deck | Copy everything (design_spec.md + SVGs + logos + assets) into <project>/templates/. Strategist locks all segments; Eight Confirmations narrows to deck-content fields (audience / page count / outline / tone tweaks). |
TEMPLATE_DIR=<user-supplied path>
cp -r ${TEMPLATE_DIR}/* <project_path>/templates/
The single-line copy suffices for all three kinds — the spec's kind field tells Strategist how to read it; downstream code doesn't distinguish.
When the user gives two or more paths of different kinds, Step 3 fuses them into a single <project>/templates/design_spec.md. Default granularity is segment-level integer replacement — entire identity / structure / middle segments are taken from the highest-priority source for that segment, no implicit field-level mixing.
Override priority by segment:
| Combination | Identity from | Structure from | Middle from |
|---|---|---|---|
| brand only | brand | (free design) | (none) |
| layout only | (free design) | layout | (none) |
| deck only | deck | deck | deck |
| brand + layout | brand | layout | (none) |
| brand + deck | brand (overrides deck) | deck | deck |
| layout + deck | deck | layout (overrides deck) | deck |
| brand + layout + deck | brand | layout | deck |
Field-level micro-adjustment (e.g. "use anthropic brand but primary changed to #FF0000") is not part of Step 3 fusion — it flows into Strategist Eight Confirmations e–g as a normal user request.
When the user gives two paths of the same kind (e.g. brands/anthropic + brands/google), Step 3 surfaces a conflict prompt before fusing — like resolving a git merge conflict:
AI: 你给了两个 brand，检测到段级冲突：
- Color Scheme（Anthropic 橙红 vs Google 多色）
- Typography（Styrene/AnthropicSans vs GoogleSans/Roboto）
- Logo（Anthropic 标 vs Google 标）
- Voice & Tone（restrained vs friendly）
- Icon Style（stroke vs filled）
要 (a) 全部按 Anthropic / (b) 全部按 Google / (c) 逐段挑？
Rules:
(c) does AI walk through each segment one by oneWhen fusion happens (any multi-path case), the resulting <project>/templates/design_spec.md carries a provenance block immediately under its H1:
> **Fused from:**
> - deck: `templates/decks/招商银行/` （base）
> - brand: `templates/brands/anthropic/` （identity override）
> - layout: `templates/layouts/academic_defense/` （structure override）
> - conflicts resolved: Color Scheme from anthropic（user picked a）
Single-path Step 3 does not add provenance (the source is self-evident from the copied files).
✅ Checkpoint — Default path proceeds to Step 4 without user interaction. If the user supplied one or more explicit template paths, those have been dispatched (or fused) into <project_path>/templates/ before advancing.
🚧 GATE: Step 3 complete; default free-design path taken, or (if triggered) template files copied into the project.
First, read the role definition:
Read references/strategist.md
⚠️ Mandatory gate: before writing
design_spec.md, Strategist MUSTread_file templates/design_spec_reference.mdand follow its full I–XI section structure. Seestrategist.mdSection 1.
Eight Confirmations (full template: templates/design_spec_reference.md):
⛔ BLOCKING: present the Eight Confirmations as a single bundled recommendation set and wait for explicit user confirmation or modification before outputting Design Specification & Content Outline. This is the single core confirmation point — once confirmed, all subsequent steps proceed automatically.
Mandatory — split-mode note (not a ninth confirmation): after listing the eight confirmation details, you MUST append exactly one short line (rendered in the user's language, prefixed with 💡) about generation mode. Pick the variant by qualitative read of Phase A signals — recommended page count, source-material bulk, whether topic-research ran with substantial web-fetch accumulation:
| Signal read | Line content |
|---|---|
| Heavy (long page count / bulky sources / heavy web-fetch accumulation) | State estimated page count and large source size; recommend switching to split mode after Step 5 — stop this chat, open a fresh window and input 继续生成 projects/<project_name> to enter Phase B (SVG generation + export); no response or "continue" = default continuous mode. |
| Normal (default) | State scale is moderate, default continuous mode generates in one go; if mid-way window switch is desired, input 继续生成 projects/<project_name> after Step 5 to switch to split mode. |
This line is required output every run — the user must always see the mode choice exists. Whether to act on it is the user's call.
Formula rendering policy lives inside item 7 (Typography plan):
| Policy | Behavior |
|---|---|
mixed (default) | Strategist renders complex formula-worthy expressions as PNG assets; simple inline expressions remain editable text / Unicode |
render-all | Strategist renders every formula-worthy expression as PNG assets |
text-only | No formula rendering; formulas remain editable text / Unicode |
After the Eight Confirmations are approved and before outputting design_spec.md / spec_lock.md, if the confirmed formula policy is mixed or render-all and the content contains formula-worthy expressions, Strategist MUST:
<project_path>/images/formula_manifest.json with only the formulas selected for rendering.python3 ${SKILL_DIR}/scripts/latex_render.py <project_path>
Acquire Via: formula, Status: Rendered, Type: Latex Formula rows in design_spec.md §VIII Image Resource List; also list them in spec_lock.md images with | no-crop.The formula renderer uses a provider fallback chain by default: codecogs,quicklatex,mathpad,wikimedia. The first three are color-aware; Wikimedia is an availability fallback. Formula PNGs are transparent by default: manifest background is the temporary render matte and transparency-removal reference, not a retained final background unless transparent: false is set for that item. Do not scan spec_lock.md for $...$ or $$...$$. Dollar-delimited math in source material is only a signal for Strategist; the renderer consumes the explicit manifest.
If the user provided images or formula PNGs were rendered, run analysis before outputting the design spec:
python3 ${SKILL_DIR}/scripts/analyze_images.py <project_path>/images
⚠️ Image handling: NEVER directly read / open / view image files (
.jpg,.png, etc.). All image info comes fromanalyze_images.pyoutput or the Design Spec's Image Resource List.
Output:
<project_path>/design_spec.md — human-readable design narrative<project_path>/spec_lock.md — machine-readable execution contract (skeleton: templates/spec_lock_reference.md); Executor re-reads before every page✅ Checkpoint — Phase deliverables complete, auto-proceed to next step:
## ✅ Strategist Phase Complete
- [x] Eight Confirmations completed (user confirmed)
- [x] Split-mode note appended below the eight items (heavy or normal variant)
- [x] Design Specification & Content Outline generated
- [x] Execution lock (spec_lock.md) generated
- [ ] **Next**: Auto-proceed to [Image_Generator / Executor] phase
🚧 GATE: Step 4 complete; Design Specification & Content Outline generated and user confirmed. Any formula rows already have Acquire Via: formula and Status: Rendered.
Trigger: At least one row in the resource list has
Acquire Via: aiand/orAcquire Via: web. If every row isuser,formula, orplaceholder, skip to Step 6.
Always load the common framework:
Read references/image-base.md
Then lazy-load the path-specific reference for each row that actually needs it:
| Acquire Via | Load reference (only if any such row exists) | Run |
|---|---|---|
ai | references/image-generator.md | python3 ${SKILL_DIR}/scripts/image_gen.py --manifest <project_path>/images/image_prompts.json |
web | references/image-searcher.md | python3 ${SKILL_DIR}/scripts/image_search.py ... |
user / placeholder | (skip) | (skip) |
A deck with only ai rows never loads image-searcher.md; a deck with only web rows never loads image-generator.md. A mixed deck loads both, processes each row through its own path, and writes both image_prompts.json and image_sources.json.
⚠️ In-pipeline ai path MUST use manifest mode — even when only 1 ai row exists. Write
images/image_prompts.jsonfirst, then runimage_gen.py --manifest, thenimage_gen.py --render-mdto produce theimage_prompts.mdsidecar. The positional form (image_gen.py "prompt" ...) is reserved for out-of-pipeline one-off testing / single-image fixups — it skips manifest + sidecar, leaving no audit trail.
Workflow:
Status: Pending and Acquire Via ∈ {ai, web} from the design specGenerated (ai success), Sourced (web success), or Needs-Manual✅ Checkpoint — Confirm acquisition attempted for every row:
## ✅ Image Acquisition Phase Complete
- [x] image_prompts.json created (when any ai rows processed)
- [x] image_prompts.md sidecar rendered (when any ai rows processed)
- [x] image_sources.json created (when any web rows processed)
- [x] Each row: status is `Generated` / `Sourced` / `Needs-Manual` (no `Pending` remaining)
Default — auto-proceed to Step 6. Only when the user's Step 4 response explicitly opted into split mode (in reply to the optional hint), output the Phase A hand-off below and stop this conversation:
## ✅ Phase A Complete
- [x] Spec: `design_spec.md`, `spec_lock.md`
- [x] Resources: `sources/`, `images/`, `templates/`
- [ ] **Next**: open a fresh chat window and input `继续生成 projects/<project_name>` to enter Phase B via the [`resume-execute`](workflows/resume-execute.md) workflow.
On acquisition failure, do NOT halt — follow the Failure Handling rule in image-base.md §5: retry once, then mark the row
Needs-Manual, report to user, and continue to the checkpoint above.
🚧 GATE: Step 4 (and Step 5 if triggered) complete; all prerequisite deliverables are ready.
Read the role definition based on the selected style:
Read references/executor-base.md # REQUIRED: common guidelines
Read references/shared-standards.md # REQUIRED: SVG/PPT technical constraints
Read references/executor-general.md # General flexible style
Read references/executor-consultant.md # Consulting style
Read references/executor-consultant-top.md # Top consulting style (MBB level)
Only read executor-base + shared-standards + one style file.
Design Parameter Confirmation (Mandatory): before the first SVG, output key design parameters from the spec (canvas dimensions, color scheme, font plan, body font size). See executor-base.md §2.
Live Preview Auto-Startup (Mandatory): before the first SVG, automatically start the browser editor in live mode and keep it running continuously through Executor + Step 7 export:
python3 ${SKILL_DIR}/scripts/svg_editor/server.py <project_path> --live
svg_output/ may be empty. Editor opens at http://localhost:5050; port conflict → --port <other> and report the actual URL.workflows/live-preview.md.svg_output/ only when the user clicks Apply changes; Ctrl+Z / Undo drops staged edits) alongside annotation; re-export stays chat-driven. Full scope and editor details: see workflows/live-preview.md Notes.Pre-generation Batch Read (Mandatory): before the first SVG, batch-read every distinct layout SVG referenced in spec_lock.page_layouts and every distinct chart SVG referenced in spec_lock.page_charts (plus any §VII backup charts). One read per file, up front — do not re-read these during page generation. See executor-base.md §1.0.
Per-page spec_lock re-read (Mandatory): before each SVG page, read_file <project_path>/spec_lock.md and use only its colors / fonts / icons / images, plus the per-page page_rhythm / page_layouts / page_charts lookups (resolves to template SVGs already loaded in the batch read above). Resists context-compression drift on long decks. See executor-base.md §2.1.
⚠️ Main-agent only: SVG generation MUST stay in the current main agent — page design depends on full upstream context. Do NOT delegate to sub-agents. ⚠️ Generation rhythm: generate pages sequentially, one at a time, in the same continuous context. Do NOT batch (e.g., 5 per group).
Visual Construction Phase: generate SVG pages sequentially, one at a time, in one continuous pass → <project_path>/svg_output/
Quality Check Gate (Mandatory) — after all SVGs, BEFORE annotation handling and speaker notes:
python3 ${SKILL_DIR}/scripts/svg_quality_checker.py <project_path>
error (banned SVG features, viewBox mismatch, spec_lock drift, etc.) MUST be fixed before proceeding — return to Visual Construction, regenerate that page, re-run check.warning entries (low-res image, non-PPT-safe font tail, etc.): fix when straightforward, otherwise acknowledge and release.svg_output/ (not after finalize_svg.py — finalize rewrites SVG and masks violations).Logic Construction Phase: generate speaker notes → <project_path>/notes/total.md
✅ Checkpoint — Confirm all SVGs and notes are fully generated and quality-checked. Proceed directly to Step 7 post-processing:
## ✅ Executor Phase Complete
- [x] Live preview started and kept available at the reported URL
- [x] All SVGs generated to svg_output/
- [x] svg_quality_checker.py passed (0 errors)
- [x] Speaker notes generated at notes/total.md
Chart pages? If this deck contains data charts (bar / line / pie / radar / etc.), run the standalone
verify-chartsworkflow before Step 7 to calibrate coordinates. AI models routinely introduce 10–50 px errors when mapping data to pixel positions; verify-charts eliminates that class of error. Skip if no chart pages.
Visual self-check (opt-in)? If the user explicitly asked for a per-page visual re-pass on the SVGs ("跑一下视觉自检 / 视觉回看", "visual review", "check pages visually", etc.), run the standalone
visual-reviewworkflow before Step 7. Do NOT run it by default and do NOT recommend it based on inferred model capability or deck size — trigger is user request only.
🚧 GATE: Step 6 complete; all SVGs generated to svg_output/; speaker notes notes/total.md generated.
🚧 Image readiness GATE (when Step 5 left ai rows in Needs-Manual): every expected file must exist at project/images/<filename> before running 7.1.
If files are missing: PAUSE, list the missing filenames, point the user to
images/image_prompts.md(each### Image N:block is paste-ready for ChatGPT / Gemini / Midjourney; auto-generated fromimage_prompts.json) and the required placementproject/images/<filename>. Resume Step 7.1 only after all expected files are in place.finalize_svg.pyandsvg_to_pptx.pydo not detect missing files at this layer — proceeding with gaps produces a deck with broken image references.
⚠️ Run the three sub-steps one at a time — each must complete successfully before the next. ❌ NEVER combine them into a single code block or shell invocation.
Canonical three-command pipeline (mirrors references/shared-standards.md §5):
Step 7.1 — Split speaker notes:
python3 ${SKILL_DIR}/scripts/total_md_split.py <project_path>
Step 7.2 — SVG post-processing (icon embedding / image crop & embed / text flattening / rounded rect to path):
python3 ${SKILL_DIR}/scripts/finalize_svg.py <project_path>
Step 7.3 — Export PPTX (embeds speaker notes by default):
python3 ${SKILL_DIR}/scripts/svg_to_pptx.py <project_path>
# Output (default-flow mode):
# exports/<project_name>_<timestamp>.pptx ← native pptx (canonical output, reads svg_output/)
# backup/<timestamp>/svg_output/ ← Executor SVG source backup (always written)
#
# Add --svg-snapshot to additionally emit the SVG-image preview pptx alongside the native pptx:
# exports/<project_name>_<timestamp>_svg.pptx ← SVG preview pptx (reads svg_final/)
The native pptx consumes
svg_output/directly so the converter can preserve high-fidelity primitives (icon<use>placeholders, imagepreserveAspectRatio→srcRect, rounded rectrx/ry→prstGeom roundRect). Thesvg_output/snapshot inbackup/<timestamp>/is always written so the project can be re-exported from frozen SVG sources without re-running the LLM. The SVG-rendered preview pptx is opt-in via--svg-snapshot— live preview already provides the SVG visual reference, so it's only needed when you want a self-contained file to share. Pass-s outputor-s finalto force a single source if you need it.
Paragraph editability vs line fidelity — by default every dy-stacked line is its own PowerPoint text frame, preserving exact SVG layout. Add
--merge-paragraphsonly when the user explicitly asks for an editable / wrap-friendly export (e.g. "I want to edit the abstract as one block", "make text boxes resizable / reflow"): mergeable paragraph blocks collapse into one editable text frame with multiple<a:p>, at the cost of PowerPoint re-wrapping inside each box. Default off keeps pixel-fidelity; turn it on per the user's request, not on your own judgement.
Optional animation flags (the defaults already enable rich entrance animations — adjust only when the user asks for something different):
-t <effect> — page transition. Default fade. Options: fade / push / wipe / split / strips / cover / random / none.-a <effect> — per-element entrance animation. Default auto (map effect from group id: chart→wipe, card-/step-/pillar-→fly, title/takeaway→fade; image-like ids hero / figure- / image / img- / kpi cycle a richer pool — zoom / dissolve / circle / box / diamond / wheel — so multiple images vary across the deck). Pass none to disable, a specific effect like fade, or mixed for the legacy 16-effect cycle. Requires top-level <g id="..."> groups (already required by Executor).--animation-trigger {on-click,with-previous,after-previous} — Start mode (matches PowerPoint's animation-pane Start dropdown). Default after-previous (click-free cascade; pace via --animation-stagger). Use on-click for presenter-paced reveals, or with-previous for all-at-once.--animation-config <path> — optional object-level sidecar. Default: <project_path>/animations.json when present.--auto-advance <seconds> — kiosk-style auto-play.Optional custom animations (only when the user asks to tune animation order/effects/timing for specific objects):
Run the standalone customize-animations workflow. Default export already has global entrance animation; do not create animations.json unless object-level customization was requested.
Optional recorded narration (only when the user asks for narrated/video export):
Run the standalone generate-audio workflow. The AI picks a narration backend (edge by default, or a configured cloud provider such as ElevenLabs / MiniMax / Qwen / CosyVoice for high-quality or cloned voices), asks the user once (backend + voice + rate/settings + embed-or-not, all with recommended values), then executes notes_to_audio.py and (if chosen) re-exports the PPTX with --recorded-narration audio.
Do NOT call notes_to_audio.py directly without going through the workflow — --voice / --voice-id is required and the workflow produces the locale/provider-aware recommendation that makes the choice meaningful.

❌ NEVER substitute
cpforfinalize_svg.py— finalize performs multiple critical processing steps ❌ NEVER force-s outputfor the legacy/preview pptx (PowerPoint's internal SVG parser drops icons and rounded corners). The default auto-split already gives native the high-fidelity source it needs without touching legacy. ❌ NEVER use--only(it suppresses one of the two output files)
Post-export annotation window: the preview service from Step 6 typically remains running after export. If the user submitted annotations in the browser (during Executor or after export) and now asks to apply them — they may quote the browser prompt (
Changes saved to svg_output.../修改已保存到 svg_output...), say "apply my annotations" / "应用注解" / equivalent — runlive-previewStep 2 to apply and re-export. Annotations submitted during generation are also handled here, not earlier.
Direct edits in the browser: the user may also stage text / SVG attribute edits in the preview. These land in
svg_output/only after the user clicks Apply changes. If they ask to "re-export" / "重新导出" after applying such edits, just re-run Step 7.2–7.3 (finalize + export); no annotation-application step is needed unless they also saved AI-needed annotations.
Preview not running? Any time the user mentions "live preview", "preview", "看效果", or wants to select/click a slide element and the service is not running, run
live-previewStep 1 to start it. If the service is already running, just point them at the URL — do not restart.
