3## Overview
4 
5This skill creates image-based PowerPoint decks from source material. Each slide is a complete 16:9 generated image. Final images are assembled into `.pptx` with `scripts/assemble_ppt.py`.

7Use this when the user wants a visually unified presentation and accepts full-slide image pages. Do not use it when every textbox, chart, or shape must remain separately editable.

9Prefer the built-in image generation/editing tool. Use `scripts/image_gen.py` only when the built-in backend is unavailable, lacks a required capability, or the user explicitly asks for API/CLI mode.

11## Hard Constraints

13- Read the relevant `Reference Map` files before each phase. This file is the orchestration contract; detailed rules live in `docs/` and worker prompts in `prompts/`.
14- Respect approval gates. Do not create final `deck_spec.json`, `speech.md`, prompt jobs, slide images, or `.pptx` before the approvals in `docs/workflow-gates-and-progress.md`.
15- After the user approves the sample slide and authorizes full-deck generation, every remaining slide image job must be dispatched to a slide subagent whenever subagents are available.
16- The main agent owns orchestration, prompt jobs, state recording, QA, speaker notes, and assembly. Do not silently replace available slide subagents with sequential production.
17- Every final `origin_image/slide_XX.png` must be generated by the selected image backend: built-in image generation/editing tool or `scripts/image_gen.py`.
