Builds single-file offline HTML talk decks from Org or Markdown outlines, with faithful layout or editorial condensing and keyboard navigation.
- Turning a Markdown or Org outline into a presentation without changing the wording
- SKILL.md covers Workflow Routing, Gotchas, 两种内容契约 and 设计与实现, plus 3 more sections
- Runs TypeScript scripts from its folder
- Distilling a talk script into on-screen statements with full speaker notes
What it does
ljg-present turns a presentation outline in Org or Markdown, or a talk script the author has authorized you to condense, into a single offline HTML deck. Slides are laid out by semantic role, such as a big statement, comparison, Unicode relationship diagram, evidence or chapter page. The default theme is a dark hacker-dark, with lighter hacker, black, red and yellow themes available. Fonts are embedded, charts are inline and there are no animations. The skill text is in Chinese.
It has two content modes. Faithful layout keeps the original wording, order, tables, code and source images when an outline exists and rewriting is not authorized. Editorial mode applies when you ask for the talk to be distilled, regrouped or its diagrams redrawn: on-screen text may then be rewritten within that grant, an editing basis is recorded and the full talk goes into speaker notes. Merely asking for a presentation does not authorize cutting the author's content. The deck is built with Tools/BuildDeck.ts and saved as an HTML file in Downloads, with keyboard navigation, F for full screen and N for notes.
When your agent uses it
- Turning a Markdown or Org outline into a presentation without changing the wording
- Distilling a talk script into on-screen statements with full speaker notes
- Redrawing an ASCII diagram as a Unicode relationship diagram
- Choosing a dark or light theme for an offline deck
Example prompts
- “Make a presentation from ./talk/outline.md exactly as written, without editing the words.”
- “Condense my talk script into slides and put the full spoken text in the speaker notes.”
- “把旧的 ASCII 图改成 Unicode 关系图并放进演示。”
Requirements
- An isolated browser (Interceptor) for the visual check
What it can do on your machine
Read from SKILL.md and the folder at commit 9e75497. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (TypeScript, from the files we listed), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Offline HTML Talk Decks loads about 506 tokens when it runs, and up to ~43k if it reads all its reference files. Until then it costs about 50 tokens; SKILL.md has 105 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

ljg-present：演讲铸造器
让观众一眼找到这一页的主角，让讲者有足够的提示继续展开。Unix 气质来自精确的关系、自然的文字、清楚的主次和有意保留的空白。
Workflow Routing
| 工作 | 入口 |
|---|---|
| 生成、重排或改进演示 | Workflows/Generate.md |
Gotchas
- share、talk 等用途标签不决定颜色。未指定视觉主题时使用 hacker-dark。
- 两行可以是一个判断。role 由讲述功能决定；行数只参与字号与分页。
- 标题、主体、提示句不是必填三件套。主句已经完成表达时，让它独立站住。
- Unicode 连接线使用等宽网格，中文节点独立排版。不要把中文逐字塞进固定字符格。
- 静态通过不等于画面成立。构建工具固定模板；浏览器探针核对实际绘制的页面，截图另检视觉主次。
两种内容契约
| 模式 | 何时使用 | 保真对象 |
|---|---|---|
| faithful 保真排版 | 已有投影提纲；未授权改写 | 原文字句、顺序、表格、代码和源图 |
| editorial 演讲编排 | 用户已要求提炼讲稿、重组展示或重绘图 | 观点、证据、限定条件、数值和关系；上屏文字可在授权范围内改写 |
当前请求已授权的提炼或重绘直接执行，不重复询问。演讲编排记录 editingBasis，上屏内容以 sourceIds 回到完整来源；完整讲述放入 notes，按 N 查看。仅有「做成演示」不自动授权删改作者内容。
设计与实现
- 先读 DesignSystem.md，按相关版式查看 CompositionReference.md 的实际样张。
- 数据契约见 RenderingSpec.md；关系图、原生图表与源代码的边界见 ChartSpec.md。
- 使用 Tools/BuildDeck.ts 把数据装入 SloganTemplate.html；不在产物末尾补 CSS，不另写渲染分支。
- 保留源中的章节转折与停顿。内容节点数、页数和图数都不是质量目标。
- 核心观点、重要限制和数据按投影距离保持可读；辅助信息退后或进入讲稿，不能缩小核心信息来制造留白。
主题
显式选择 > 明确的 theme_* 视觉标签 > hacker-dark。普通话题、用途标签不参与主题选择。
| 意图或参数 | theme |
|---|---|
| 默认、Unix、terminal、暗色 | hacker-dark |
| 浅色 Hacker、--hacker、兼容 --cyber | hacker |
| -b / --theme=black | black |
| -r / --theme=red | red |
| -y / --theme=yellow | yellow |
交付
一个 ~/Downloads/{title}.html，字体内嵌，图表内联，离线、零动效。→ ↓ Space Enter j PageDown 前进；← ↑ k PageUp 后退；Home/End 首末页；F 全屏；N 讲稿。滚动图形和讲稿时不触发翻页。
静态验证检查当前模板与源数据；使用 Interceptor 隔离浏览器加载 Tools/ProbeDeck.js，再看整套缩略图与代表页。隔离浏览器不可用时保留产物并如实报告未完成视觉复验，不改用主浏览器冒充验收。
Examples
- 「按原提纲做演示，别改字」→ faithful，根据语义选版式，必要时沿源边界续页。
- 「把讲述精髓放进展示，供我现场展开」→ editorial，提炼主张、对照或关系，完整讲稿进入 notes。
- 「把旧 ASCII 图改成 Unicode」→ 记录重绘授权，以节点、连接和方向核对新图；真实代码仍逐字符保留。
