拆一本书。冷静简洁犀利直白，五件事说清：作者在答什么问题，立在什么不证之物上，用什么框架看，得出什么结论，最后萃出一个 takeaway（取景框/模型/洞见/概念/金句五选一）作为这本书的精神内核。Use when user says '拆书', '拆这本', '分析这本书', '这本书在讲什么', '上帝之眼看这本书', '压缩一本书', 'book', or shares a book name wanting structural analysis. NOT FOR 章节摘要（用 Fabric extract_wisdom）、论文（用 ljg-paper）、单一观点深钻（用 ljg-think）、一个领域降秩（用 ljg-rank）.

Paper reader for non-academics. Reads a paper and tells it back as one continuous story to someone who doesn't know the field — built on a seven-beat spine (主角 / 困境 / 旧路 / 转折 / 解法 / 结局 / 内核). The job is storytelling that makes the paper land, not academic critique. Use when user shares an arxiv link, paper URL, PDF, or asks to analyze a research paper. Trigger words: '读论文', '讲论文', '把这篇讲给我听', '分析论文', 'paper', or when user shares an academic paper.

把 ~/.claude/skills/ljg-* 里所有更新过的 skills 同步到 github repo (ljg-skills)，先推 master 分支（org-mode 输出风格），再切 md 分支（markdown 输出风格）做基础 markdown 化后推。Use when user says '/ljg-push', 'push skills', '推送 skills', '同步 skills', 'sync ljg', or whenever ljg-* skills get updated and need shipping. NOT FOR pushing non-ljg skills or arbitrary git repos.

给一个领域，找出背后真正撑着它的几根独立的力。十几个现象砍到不可再少的生成器——砍完能把现象一个个生回来，才算数。Use when user says '降秩', '找秩', '秩是什么', '这个领域靠什么撑着', '背后是什么', or wants to decompose any domain to its irreducible generators.

演讲铸造器（Outline-Faithful）。基于 orgmode/markdown outline 层级 1:1 视觉化呈现——色块大字、ultra-bold 错位，原文不动只做美化。三档主题色 black/red/yellow（默认 black 或按 filetags 推断），可用 -r/-b/-y 显式覆盖；可用 --cyber 走黑底绿字 cyber-hacker 风。使用时用户会说：'讲这个'、'present'、'做成演讲'、'呈现一下'、'铸成演示'、'做个 slides'、'标语流'、'宣言体'、'slogan'、'manifesto'、'按 outline 美化'。输出单文件 HTML 到 ~/Downloads/。

Content caster (铸). Transforms content into PNG visuals. Seven molds: -l (default) long reading card, -i infograph, -m multi-card reading cards (1080x1440), -v editorial sketchnote (problem→failure→pivot→insight→naming, magazine + archive layout), -c comic (manga-style B&W), -w whiteboard (marker-style board layout), -b big-fonts attachment card (1080x1440, weathered 碑刻 style for 小红书). Output to ~/Downloads/. Use when user says '铸', 'cast', '做成图', '做成卡片', '做成信息图', '做成海报', '视觉笔记', 'sketchnote', '杂志', 'editorial', '漫画', 'comic', 'manga', '白板', 'whiteboard', '大字', '附件图', 'big fonts', '小红书卡片'. Replaces ljg-cards and ljg-infograph.

信息提问机。给一篇文章/论文/书，把核心观点抽成 Q-A 对——Question 切要害，不教科书；Answer 简洁清晰，有形式化收口，逻辑链完整。读者顺 Q 链走过，每个 A 砸下一枚钉子，复现作者整套推理。Use when user says '问答', 'Q&A', 'QA', '提问', '抽取问题', '/ljg-qa', or shares an article/paper/book and asks for Q-A extraction. Triggers when the user wants ideas extracted not as a summary but as a sequence of incisive questions with answered. NOT FOR FAQ generation, glossary creation, or comprehension quizzes — this is intellectual scaffolding, not study aids.

Paper workflow: read papers + cast cards in one go. Takes one or more arxiv links, paper URLs, PDFs, or paper names. For each paper, runs ljg-paper (generates org analysis) then ljg-card -v (generates visual sketchnote PNG). Use when user says '论文流', 'paper flow', '读论文并做卡片', '论文卡片', or provides multiple papers wanting both analysis and cards.

Paper X-ray. Extracts what the paper says (problem-perspective-result) and what it means for lijigang (cognitive delta cards in ASCII art). Use when user shares an arxiv link, paper URL, PDF, or asks to analyze a research paper. Usually called via ljg-xray router. Do NOT use for blog posts or non-academic articles (use ljg-xray-article instead).

Deep structure extraction from books using the Epiplexity principle - maximizing computational investment to extract maximum learnable structure from any book.

Deep-dive English word mastery tool. Deconstructs a single English word into core semantics and epiphany. Use when user asks to explain/master a specific English word. Do NOT use for Chinese concepts or multi-word ideas (use ljg-explain-concept).

Deep concept anatomist that deconstructs any concept through 8 exploration dimensions (history, dialectics, phenomenology, linguistics, formalization, existentialism, aesthetics, meta-philosophy) and compresses insights into an epiphany. Use when user asks to explain, dissect, or deeply understand a concept, term, or idea. Produces org-mode output.

Structured roundtable discussion framework with a truth-seeking moderator who invites representative figures for dialectical debate on any topic. Use when user says "圆桌讨论", "圆桌", "roundtable", "辩论", or wants to explore a topic through multi-perspective structured debate.

X-ray scans articles (blog posts, essays, opinion pieces) to extract the real question and cognitive collisions. Use when user shares a non-academic article URL or text for deep structural analysis. Do NOT use for academic papers (use ljg-xray-paper) or books (use ljg-xray-book).

Extracts the essential formula (The One) from books, concepts, or ideas using first-principles thinking, then falsifies it by identifying boundary conditions. Generates a visual HTML card. Use for quick single-formula essence extraction. For deep multi-round book analysis, use ljg-xray-book instead. Do NOT use for academic papers (use ljg-xray-paper).

Generates a real-time ASCII topology of all ljg-* skills, organized by CogOS layers (Intake, Decompose, Synthesize, Create, Reflect, Meta). Use when user says "skill地图", "skill拓扑", "画个技能图", or asks to see the current skill system layout.
