Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.

每当涉及 .pptx 文件时，无论作为输入、输出还是两者兼具，都使用本技能。这包括：创建幻灯片、路演材料或演示文稿；读取、解析或从任何 .pptx 文件中提取文本（即使提取内容将用于其他地方，如邮件或摘要）；编辑、修改或更新现有演示文稿；合并或拆分幻灯片文件；处理模板、版式、演讲者备注或评论。只要用户提及“deck”、“slides”、“presentation”或引用 .pptx 文件名，无论其后续如何使用内容，均触发本技能。若需打开、创建或操作 .pptx 文件，一律使用本技能。
