# PPT Design Skill **⚠️ READ BEFORE coding: [`src/ppt_pro_max/docs/python-pptx-reference.md`](src/ppt_pro_max/docs/python-pptx-reference.md)** — 170+ shape types, 73 chart types, tables, connectors, freeform, hyperlinks, media, effects, 3D, OOXML. python-pptx has far more capabilities than rect/oval/textbox. AI-powered PPT generation — three-mode engine, 40,000+ style combos, 10 diagram types, brand compliance, version control, fully editable .pptx. ## ⚠️ Non-Negotiable Sections (DO NOT compress or remove) These sections are the LLM's only reference for writing correct output: 1. **content.json Format** — LLM must know the exact schema to write valid content 2. **brand.json Format** — LLM must know brand spec structure for VI Build mode 3. **Build Helpers API** — LLM must know function signatures to write build.py 4. **Content Design Rules** — LLM must know which content patterns trigger which rendering 5. **Key Constraints** — LLM must know API signatures to write correct python-pptx code 6. **generate_ppt() signature** — LLM must know valid parameters to call the pipeline ## Execution Workflow ALWAYS follow this 5-step workflow. Each step requires user confirmation before proceeding. Do NOT skip steps or generate final PPT directly — rework is extremely costly. ### Step 1: Requirements & Framework - Understand: topic, audience, language, scenario - Read any user-provided materials (README, docs, data files) - Design the skeleton: total pages, per-page goal, core tit...
