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 Option → Strategist → [Image_Generator] → Executor → 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

[!IMPORTANT]

🌐 Language & Communication Rule

• Response language: Always match the language of the user's input and provided source materials. For example, if the user asks in Chinese, respond in Chinese; if the source material is in English, respond in English.
• Explicit override: If the user explicitly requests a specific language (e.g., "请用英文回答" or "Reply in Chinese"), use that language instead.
• Template format: The design_spec.md file MUST always follow its original English template structure (section headings, field names), regardless of the conversation language. Content values within the template may be in the user's language.

[!IMPORTANT]

🔌 Compatibility With Generic Coding Skills

• pptx-master is a repository-specific workflow skill, not a general application scaffold
• Do NOT create or require .worktrees/, tests/, branch workflows, or other generic engineering structure by default
• If another generic coding skill suggests repository conventions that conflict with this workflow, follow this skill first unless the user explicitly asks otherwise

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).

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

User Provides	Command
PDF file	python3 ${SKILL_DIR}/scripts/pdf_to_md.py <file>
DOCX / Word / Office document	python3 ${SKILL_DIR}/scripts/doc_to_md.py <file>
EPUB / HTML / LaTeX / RST / other	python3 ${SKILL_DIR}/scripts/doc_to_md.py <file>
Web link	python3 ${SKILL_DIR}/scripts/web_to_md.py <URL>
WeChat / high-security site	node ${SKILL_DIR}/scripts/web_to_md.cjs <URL>
Markdown	Read directly

✅ 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).

bash

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 --copy: All source files (original PDF / MD / images) MUST be copied (not moved) into sources/ for archiving.

• Markdown files generated in Step 1, original PDFs, original MDs — all must be copied into the project via import-sources --copy
• Intermediate artifacts (e.g., _files/ directories) are handled automatically by import-sources
• Original source files remain at their original location after copying

✅ Checkpoint — Confirm project structure created successfully, sources/ contains all source files, converted materials are ready. Proceed to Step 3.

---

Step 3: Template Selection

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

⛔ BLOCKING: If the user has not yet clearly expressed whether to use a template, you MUST present options and wait for an explicit user response before proceeding. If the user has previously stated "no template" or specified a particular template, skip this prompt and proceed directly.

⚡ Early-exit: If the user has already stated "no template" / "不使用模板" / "自由设计" (or equivalent) at any prior point in the conversation, do NOT query layouts_index.json — skip directly to Step 4. This avoids unnecessary token consumption.

Template recommendation flow (only when the user has NOT yet decided): Query ${SKILL_DIR}/templates/layouts/layouts_index.json to list available templates and their style descriptions. Note: New templates include HUAWEI and red grey layouts. When presenting options, you MUST provide a professional recommendation based on the current PPT topic and content (recommend a specific template or free design, with reasoning), then ask the user:

💡 AI Recommendation: Based on your content topic (brief summary), I recommend [specific template / free design] because...

Which approach would you prefer? A) Use an existing template (please specify template name or style preference - note: new options include HUAWEI and red grey templates) B) No template — free design

After the user confirms option A, copy template files to the project directory:

bash

cp ${SKILL_DIR}/templates/layouts/<template_name>/*.svg <project_path>/templates/
cp ${SKILL_DIR}/templates/layouts/<template_name>/design_spec.md <project_path>/templates/
cp ${SKILL_DIR}/templates/layouts/<template_name>/*.png <project_path>/images/ 2>/dev/null || true
cp ${SKILL_DIR}/templates/layouts/<template_name>/*.jpg <project_path>/images/ 2>/dev/null || true

After the user confirms option B, proceed directly to Step 4.

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

✅ Checkpoint — User has responded with template selection, template files copied (if option A). Proceed to Step 4.

---

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

🚧 GATE: Step 3 complete; user has confirmed template selection.

First, read the role definition:

text

Read references/strategist.md

Must complete the Eight Confirmations (refer to templates/design_spec_reference.md for the template structure):

⛔ BLOCKING: The Eight Confirmations MUST be presented to the user as a bundled set of recommendations, and you MUST wait for the user to confirm or modify before outputting the Design Specification & Content Outline. This is one of only two core confirmation points in the workflow (the other is template selection). Once confirmed, all subsequent script execution and slide generation should proceed fully 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

If the user has provided images, run the analysis script before outputting the design spec (do NOT directly read/open image files — use the script output only):

bash

python3 ${SKILL_DIR}/scripts/analyze_images.py <project_path>/images

⚠️ Image handling rule: The AI must NEVER directly read, open, or view image files (.jpg, .png, etc.). All image information must come from the analyze_images.py script output or the Design Specification's Image Resource List.

Output: <project_path>/design_spec.md

✅ Checkpoint — Phase deliverables complete, auto-proceed to next step:

markdown

## ✅ Strategist Phase Complete
- [x] Eight Confirmations completed (user confirmed)
- [x] Design Specification & Content Outline generated
- [ ] **Next**: Auto-proceed to [Image_Generator / Executor] phase

---

Step 5: Image_Generator Phase (Conditional)

🚧 GATE: Step 4 complete; Design Specification & Content Outline generated and user confirmed.

Trigger condition: Image approach includes "AI generation". If not triggered, skip directly to Step 6 (Step 6 GATE must still be satisfied).

Read references/image-generator.md

1. Extract all images with status "pending generation" from the design spec
2. Generate prompt document → <project_path>/images/image_prompts.md
3. Generate images (CLI tool recommended):

   bash

   python3 ${SKILL_DIR}/scripts/image_gen.py "prompt" --aspect_ratio 16:9 --image_size 1K -o <project_path>/images
   

✅ Checkpoint — Confirm all images are ready, proceed to Step 6:

markdown

## ✅ Image_Generator Phase Complete
- [x] Prompt document created
- [x] All images saved to images/

---

Step 6: Executor Phase

🚧 GATE: Step 4 (and Step 5 if triggered) complete; all prerequisite deliverables are ready.

Read the role definition based on the selected style:

text

Read references/executor-base.md          # REQUIRED: common guidelines
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 need to read executor-base + one style file.

Design Parameter Confirmation (Mandatory): Before generating the first SVG, the Executor MUST review and output key design parameters from the Design Specification (canvas dimensions, color scheme, font plan, body font size) to ensure spec adherence. See executor-base.md Section 2 for details.

⚠️ Main-agent only rule: SVG generation in Step 6 MUST remain with the current main agent because page design depends on full upstream context (source content, design spec, template mapping, image decisions, and cross-page consistency). Do NOT delegate any slide SVG generation to sub-agents. ⚠️ Generation rhythm rule: After confirming the global design parameters, the Executor MUST generate pages sequentially, one page at a time, while staying in the same continuous main-agent context. Do NOT split Step 6 into grouped page batches such as 5 pages per batch.

Visual Construction Phase:

• Generate SVG pages sequentially, one page at a time, in one continuous pass → <project_path>/svg_output/

Logic Construction Phase:

• Generate speaker notes → <project_path>/notes/total.md

✅ Checkpoint — Confirm all SVGs and notes are fully generated. Proceed directly to Step 7 post-processing:

markdown

## ✅ Executor Phase Complete
- [x] All SVGs generated to svg_output/
- [x] Speaker notes generated at notes/total.md

---

Step 7: Post-processing & Export

🚧 GATE: Step 6 complete; all SVGs generated to svg_output/; speaker notes notes/total.md generated.

⚠️ The following three sub-steps MUST be executed individually one at a time. Each command must complete and be confirmed successful before running the next. ❌ NEVER put all three commands in a single code block or single shell invocation.

Step 7.1 — Split speaker notes:

bash

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):

bash

python3 ${SKILL_DIR}/scripts/finalize_svg.py <project_path>

Step 7.3 — Export PPTX (embeds speaker notes by default):

bash

python3 ${SKILL_DIR}/scripts/svg_to_pptx.py <project_path> -s final
# Default: generates two files — native shapes (.pptx) + SVG reference (_svg.pptx)
# Use --only native  to skip SVG reference version
# Use --only legacy  to only generate SVG image version

❌ NEVER use cp as a substitute for finalize_svg.py — it performs multiple critical processing steps ❌ NEVER export directly from svg_output/ — MUST use -s final to export from svg_final/ ❌ NEVER add extra flags like --only
