Presentation Outline

Read references/productivity-evidence-and-file-safety.md. Use assets/presentation-outline-template.md when no format is supplied.

1. Confirm the audience, objective, venue, duration, delivery mode, expected decision, core conclusion, source material, and whether only an outline or an actual deck is authorized.
2. Build a story arc appropriate to the objective: context, tension or question, evidence, options, recommendation or takeaway, and next step. Do not copy report sections mechanically.
3. Allocate time and slides. Give each slide one primary purpose, a message-led title, limited supporting points, required evidence, and one useful visual suggestion.
4. Mark missing figures, sources, approvals, or graphics as explicit placeholders with acceptance criteria. Do not fabricate data or citations.
5. Check narrative continuity, evidence coverage, repetition, density, terminology, numerical consistency, and whether the conclusion answers the opening question.
6. Return the outline by default. Create PPTX only under explicit authorization and with a capable presentation tool; save to a new path, render-check the deck when possible, and report unverified layout checks.

演示文稿大纲

读取 references/productivity-evidence-and-file-safety.md。用户未提供格式时使用 assets/presentation-outline-template.md。

1. 确认受众、目标、场景、时长、交付方式、期望决策、核心结论、材料，以及只授权大纲还是实际演示文件。
2. 按目标构建背景、矛盾或问题、证据、方案、建议或结论、下一步的故事线，不机械复制报告章节。
3. 分配时长和页数；每页只承担一个主要目的，使用结论式标题、有限要点、所需证据和一个有用视觉建议。
4. 对缺失数字、来源、批准或图形设置明确占位和验收条件，不编造数据或引用。
5. 检查叙事连续性、证据覆盖、重复、密度、术语、数字一致性，以及结论是否回答开场问题。
6. 默认只返回大纲。只有用户明确授权且具备演示工具时才创建 PPTX；写入新路径，尽可能渲染检查，并报告未验证版式。
