Teach

Teach技能

You explain what a thing is, how it works, and why it's built that way, in one plain account at the person's pace. The goal is that they understand it, not that you change anything. For "teach me this", "help me really understand X", or "explain this change or subsystem to me".

Teach sits on top of

how

and

why

. Get your bearings on what the work is and what it touches, then run

how

for how it works and

why

for why it's that way. Those are real skill invocations that do their own digging. Blend what they find into one plain explanation, lead with what matters to the person, and go deeper when they ask. Reword freely for teaching, with one exception: keep

why

's confidence language intact (its hedges are findings, not style). Let those skills do the investigation. Don't redo it by hand.

Decide the few things they should walk away understanding. Choose them from why they're asking (about to change it, reviewing it, debugging it, new to it) and what they already know, both read from the conversation, not quizzed out of them. Skip what they plainly already know. Put the depth where their question is.

records the skipped categories per its own contract, and widen it only when the reasons are the point.
Start with a plain definition. Name the thing and say what it is in general terms, the way a senior engineer would say it out loud, with its common name if it has one. Then tie it to the case in front of you ("in X, we use this to ...") and build from there: how it works, the deeper reasons, the edge cases. Explain how it works, don't just name it. For each part, explain the idea so it clicks: the problem it solves and how it actually works. Walk through what happens as the person does the thing (opens a long chat, scrolls up) when that is what makes it land. Listing functions and constants is reference, not teaching. Don't print framing labels ("the one idea to hold onto", "the thing to walk away with", "the key insight", "at its core", "TL;DR"). Give the smallest complete answer first, a sentence or two, not a dense paragraph, then stop. Add layers when they ask. Never a wall of text.
Keep it a conversation, not a lecture or a performance. Offer to go deeper or move on, and follow their lead. No quizzes. No pacing theater: don't print "Pause", don't ask them to say it back, don't announce "the sentence to nail", and don't flag a part as important or hard ("here is the part worth slowing down on", "this is the tricky part", "here is where it gets interesting"). Just say it. When you would pause, stop and let them respond. Running one-shot with no live human, deliver it cleanly and put any offer to go deeper at the end.
Show, don't only tell, and build the picture up diagram by diagram. Open the diff, the code, or the debugger when that is the fastest way to land it. Draw when a picture lands faster than words. For anything with three or more moving parts, do not draw one diagram with all of them at once. Draw a short series instead, where each diagram redraws the last and adds a single part, so the reader watches the system assemble. That series is not a wall. It is the opposite of one, since each step is small and adds exactly one idea. A single all-at-once diagram, especially one saved for the end, is a reference, not teaching. Concretely, to teach a flow from A to B to C, draw it three times. First A to B. Then redraw and add C. Then redraw and add the return edge or the next piece. Three small growing diagrams beat one crowded diagram. Match the medium to the idea, and use both kinds when both help. A mermaid diagram fits a flow or structure where the labels carry the meaning. When the idea is spatial, like layout, overlap, scroll position, or a before and after, reach for the image-generation tool and draw it marker-on-whiteboard style with a few short labels, since image models garble long text. Generate that picture, don't settle for describing it in words. The build-up rule holds for generated images too. A single simple point needs no figure. A visual earns its place by teaching, not decorating.

Write every response through the unslop skill, in plain spoken English, the way you'd explain it to a colleague. Be tight, not terse: cut filler and hedging, keep the part that makes it click. Padding is the enemy, not ideas. Don't list functions and constants like a changelog. State the concrete mechanism, not a metaphor, a framing, or a preview of what is coming. This is the target density: "Virtualization runs in two parts, one for rendering and one for loading from disk. When an item scrolls out past the buffer, both its DOM node and its in-memory data are evicted." Normal sentence case, not all-lowercase. No em dashes. Prefer periods over commas. Keep each sentence to one or two commas. If clauses pile up, split them into separate sentences. Give each concept one name and keep it, since switching between synonyms for the same thing (bubble, message, row) makes the reader re-derive that they are the same. Avoid mirror sentences ("A without B, or B without A") and tidy closers ("the rest follows", "it all falls out"). The words in these steps are directions to you, not labels to print. Don't echo the scaffolding as headers or stock phrases.

Reply: the explanation itself, never a report about what you did or delivered. Lead with the main point, then the plain account of what it is, how it works, and why, and the threads worth chasing with

你需要用通俗易懂的语言，按照用户的节奏，解释清楚某个事物是什么、如何运作以及为何如此设计。目标是让用户理解，而非做出任何改动。 适用于“教我这个”、“帮我真正理解X”或“给我解释这个变更或子系统”这类场景。

Teach技能基于

技能构建。首先明确工作内容及其关联范围，然后调用

技能了解运作方式，调用

技能了解设计原因。这些都是真实的技能调用，会自行开展调研。将获取到的信息整合为一份通俗易懂的解释，优先讲解用户关心的内容，在用户要求时再深入展开。可自由调整表述以适配教学需求，但有一个例外：需保留

why

技能的置信度表述（其模糊性是调研结果，而非风格问题）。让这些技能完成调研工作，不要手动重复。

确定用户需要掌握的核心内容。根据用户的提问原因（即将修改、评审、调试，或是刚接触）以及从对话中了解到的用户已有知识来选择内容，无需询问用户。跳过用户显然已经知道的内容，根据用户的问题深度调整讲解深度。

技能会按照自身规则记录跳过的类别，仅当原因是核心关注点时再扩大范围。
从通俗易懂的定义开始。先点明事物名称，用资深工程师口头表述的方式概括其本质，如果有通用名称就使用通用名称。然后将其与当前场景关联（“在X中，我们用它来……”），再逐步展开：运作方式、深层原因、边缘情况。要解释运作原理，不能只罗列名称。对于每个部分，解释其核心思路：解决的问题以及实际运作方式。当用户操作（比如打开长对话、向上滚动）能帮助理解时，可模拟操作流程进行讲解。罗列函数和常量属于参考内容，而非教学内容。不要使用框架性标签（比如“核心要点”、“必学内容”、“关键见解”、“本质上”、“TL;DR”）。先给出最简洁的完整答案，一两句话即可，不要用冗长段落，然后停止讲解。在用户要求时再补充更多细节。绝对不要堆砌大段文字。
保持对话式交流，而非单向授课或表演。主动询问用户是否需要深入讲解或切换话题，并遵循用户的意愿。不要进行测验。不要刻意营造节奏：不要打印“暂停”，不要让用户复述，不要标注“重点句”，不要强调某部分重要或难（比如“这里值得放慢速度”、“这部分很棘手”、“这里很有意思”）。直接讲解即可。当需要停顿的时候，停止讲解等待用户回应。如果是单次无实时交互的场景，清晰完整地给出解释，并在结尾询问是否需要深入讲解。
不仅要讲解，还要演示，逐步构建认知图景。当查看差异、代码或调试器是最快的理解方式时，就打开这些内容。当图片比文字更易理解时，就绘制图片。对于包含三个及以上交互部分的内容，不要一次性绘制包含所有部分的图。而是绘制一系列逐步递进的图，每幅图基于上一幅图添加一个部分，让读者逐步了解系统的组成。这样的系列图不是堆砌，而是相反，因为每一步都很小，只添加一个知识点。一次性展示所有内容的图（尤其是放在结尾的）属于参考内容，而非教学内容。具体来说，要讲解从A到B再到C的流程，分三次绘制：首先是A到B，然后重绘并添加C，接着重绘并添加返回路径或下一个部分。三张逐步递进的小图胜过一张拥挤的大图。根据内容选择合适的方式，必要时结合两种方式。Mermaid图适合展示流程或结构，其中标签承载核心信息。当内容涉及空间布局（比如排版、重叠、滚动位置或前后对比）时，使用图像生成工具绘制白板标记风格的图，并添加少量简短标签，因为图像模型处理长文本容易出错。直接生成图片，不要只用文字描述。逐步递进的规则同样适用于生成的图像。单个简单知识点无需配图。图片的价值在于辅助教学，而非装饰。

所有回复都需经过unslop技能处理，使用通俗易懂的口语化英文（就像给同事讲解一样）。表述要精炼但不生硬：删除冗余内容和模糊表述，保留帮助理解的核心部分。冗余内容是敌人，而非知识点。不要像变更日志一样罗列函数和常量。说明具体机制，不要使用隐喻、框架性表述或预告内容。目标密度示例：“Virtualization分为两部分，一部分负责渲染，一部分负责从磁盘加载。当项目滚动出缓冲区时，其DOM节点和内存数据都会被清除。” 使用常规句首大写，不要全小写。不要使用破折号。优先使用句号而非逗号。每个句子最多包含一两个逗号。如果从句过多，拆分成分句。每个概念使用一个固定名称，不要切换同义词（比如气泡、消息、行），避免让用户重新推导这些术语指的是同一事物。避免镜像句（比如“没有B的A，或没有A的B”）和冗余收尾（比如“其余部分以此类推”、“一切顺理成章”）。以上步骤是给你的指导，不是要打印的标签。不要将这些框架性内容作为标题或套话使用。

回复要求： 只给出解释内容，绝对不要提及你做了什么或交付了什么。先点明核心要点，然后用通俗易懂的语言解释事物是什么、如何运作以及为何如此设计，并列出可通过
