PPT Master Skill

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:

1. 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"
2. 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
3. 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)
4. GATE BEFORE ENTRY — Each Step has prerequisites (🚧 GATE) listed at the top; these MUST be verified before starting that Step
5. NO SPECULATIVE EXECUTION — "Pre-preparing" content for subsequent Steps is FORBIDDEN (e.g., writing SVG code during the Strategist phase)
6. 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
7. 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
8. 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's page_rhythm (anchor / dense / breathing), page_layouts (which template SVG to inherit, if any), and page_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
9. 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.md MUST follow its original English template structure (section headings, field names) regardless of conversation language. Content values may be in the user's language.

[!IMPORTANT]

🔌 Compatibility With Generic Coding Skills

• ppt-master is a repository-specific workflow, not a general application scaffold
• Do NOT create .worktrees/, tests/, branch workflows, or generic engineering structure by default
• On conflict with a generic coding skill, follow this skill unless the user explicitly says otherwise

create-template	workflows/create-template.md	Standalone template creation workflow
resume-execute	workflows/resume-execute.md	Phase B entry — resume execution in a fresh chat after Phase A (Step 1–5) completed in another session (split mode)
verify-charts	workflows/verify-charts.md	Chart coordinate calibration — run after SVG generation if the deck contains data charts
customize-animations	workflows/customize-animations.md	Object-level PPTX animation customization — run only when the user explicitly asks to tune animation order/effects/timing
live-preview	workflows/live-preview.md	Browser-based live preview — auto-started during generation and re-enterable any time the user mentions "live preview", "preview", "看效果", or wants to click/select a slide element

Workflow

Step 1: Source Content Processing

🚧 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-research workflow first, then return here with its products as input.

When the user provides non-Markdown content, convert immediately:

User Provides	Command
PDF file	python3 ${SKILL_DIR}/scripts/source_to_md/pdf_to_md.py <file>
DOCX / Word / Office document	python3 ${SKILL_DIR}/scripts/source_to_md/doc_to_md.py <file>
XLSX / XLSM / Excel workbook	python3 ${SKILL_DIR}/scripts/source_to_md/excel_to_md.py <file>
CSV / TSV	Read directly as plain-text table source
PPTX / PowerPoint deck	python3 ${SKILL_DIR}/scripts/source_to_md/ppt_to_md.py <file>
EPUB / HTML / LaTeX / RST / other	python3 ${SKILL_DIR}/scripts/source_to_md/doc_to_md.py <file>
Web link	python3 ${SKILL_DIR}/scripts/source_to_md/web_to_md.py <URL>
WeChat / high-security site	python3 ${SKILL_DIR}/scripts/source_to_md/web_to_md.py <URL> (requires curl_cffi, included in requirements.txt)
Markdown	Read directly

Office vector assets (EMF/WMF) from DOCX/PPTX sources: doc_to_md.py / ppt_to_md.py extract embedded Office vector images (.emf/.wmf) alongside bitmap images. After import-sources, these land in images/ together with image_manifest.json and 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.py skips them) and svg_to_pptx.py embeds them as PPTX-native media via image/x-emf / image/x-wmf MIME — 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.

---

Step 2: Project Initialization

🚧 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 into sources/ via import-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.

---

Step 3: Template Option

🚧 GATE: Step 2 complete; project directory structure is ready.

Default — free design. Proceed directly to Step 4. Do NOT query layouts_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 an explicit template directory path supplied by the user in their initial message. The trigger rule is mechanical, not interpretive:

User input contains	Step 3 action
An explicit path to a template directory (e.g. skills/ppt-master/templates/layouts/academic_defense/, projects/foo/template/, or any other absolute / relative path that resolves to a directory containing design_spec.md and one or more page SVGs)	Copy that directory's SVGs + design_spec.md + assets into the project, advance
Anything else — including bare template names ("用 academic_defense 模板"), style descriptions ("麦肯锡风格" / "Google style"), 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 template name without a path does not trigger — the user must give a path the AI can cd into.

The path may live anywhere — skills/ppt-master/templates/layouts/<name>/ (the built-in library), projects/<other_project>/template/ (reusing a previous project's templates), or any other location. Location is irrelevant; what matters is that the user named the path.

TEMPLATE_DIR=<user-supplied path>
cp ${TEMPLATE_DIR}/*.svg <project_path>/templates/
cp ${TEMPLATE_DIR}/design_spec.md <project_path>/templates/
cp ${TEMPLATE_DIR}/*.png <project_path>/images/ 2>/dev/null || true
cp ${TEMPLATE_DIR}/*.jpg <project_path>/images/ 2>/dev/null || true

Style descriptions ("麦肯锡风格" / "Keynote 风" / "极简风" / etc.) never trigger Step 3. They flow naturally into Strategist's Eight Confirmations as part of the user's input — Strategist uses them as a style brief when proposing color / typography / tone in confirmations e and g.

Bare template names ("academic_defense", "招商银行") do NOT trigger Step 3 even if a folder by that name 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 layouts_index.json together with their paths. Listing alone does not advance the pipeline; the user still has to send a path to trigger the Step 3 copy.

To create a new template, read workflows/create-template.md.

✅ Checkpoint — Default path proceeds to Step 4 without user interaction. If the user's input contains an explicit template directory path, that directory is copied before advancing.

---

Step 4: Strategist Phase (MANDATORY — cannot be skipped)

🚧 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 MUST read_file templates/design_spec_reference.md and follow its full I–XI section structure. See strategist.md Section 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.

1. Canvas format
2. Page count range
3. Target audience
4. Style objective
5. Color scheme
6. Icon usage approach
7. Typography plan
8. Image usage approach

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-fe
