ljg-skills is a collection of custom Codex skills for tasks such as learning, writing, reading, relationship analysis, image creation, and investment analysis. Codex users install selected skills or the whole collection through a skills command-line interface. The catalogue entries are the collection's individual skills, plugin, and instruction.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00144 | $0.03777 |
| Opus 5 | $0.00072 | $0.01888 |
| Sonnet 5 | $0.00029 | $0.00755 |
| Haiku 4.5 | $0.00014 | $0.00378 |
Grade A, and why
ljg-present scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ljg-present：演讲铸造器
把 outline 铸成舞台。内容由作者决定，skill 只决定它如何被看见。
核心契约
Outline 是真理，Skill 是渲染器。
- 标题、段落、列表项、引用不改字。
- 表格不改结构，example/代码块不改空格与换行。
- 所有源元素按原顺序出现；不抽提、不浓缩、不重排。
- 唯一允许改变的是物理分页与视觉构图。
#+title:是文档标题，必须先生成独立 cover；第一个 outline 节点仍在下一页。若两者文字完全相同，可合并为 cover，不能重复。
Workflow Routing
| Workflow | Trigger | File |
|---|---|---|
| Generate | 讲这个、present、做成演讲、slides、按 outline 美化、生成 HTML 演示 | Workflows/Generate.md |
生成时先读 RenderingSpec.md，再使用根目录 SloganTemplate.html。不要根据记忆重造模板。
Quick Reference
输入与输出
- 输入：Orgmode、Markdown 或纯文本。
- 输出：
~/Downloads/{title}.html，单文件、离线、无外链资源。 - 首屏：文档标题 cover。
- 空间节奏：所有文字页共享稳定中轴；cover 与章节页靠深浅色场、字号和居中短信号线区分。
- Header：不承载任何信息。
- Footer：首页显示页码与 subtitle/meta；其他页只显示页码。
Theme
优先级：显式参数 > #+filetags: > 默认 black。
| 参数 | theme | 调性 |
|---|---|---|
-b / --theme=black |
black | 沉思、论证 |
-r / --theme=red |
red | 宣言、号召 |
-y / --theme=yellow |
yellow | 反讽、警觉 |
--hacker |
hacker | 逆向工程实验纸 |
--cyber |
hacker | 兼容别名；不再生成 CRT/HUD |
--theme=hacker-dark |
hacker-dark | 低眩光深色终端；全页暗场、柔和灰绿正文 |
Hacker 有两个静态阅读变体。二者都拒绝荧光特效堆叠：
--hacker-void: #07110D;
--hacker-paper: #EAF4EC;
--hacker-signal: #00C46A;
--hacker-dark-bg: #06110D;
--hacker-dark-deep: #020806;
--hacker-dark-panel: #0A1A13;
--hacker-dark-fg: #CFE1D5;
--hacker-dark-signal: #25E981;
hacker 的普通页使用浅色实验纸；hacker-dark 的所有页面使用深色场，cover 与一级章节再压深一档。暗色正文不是纯白，而是柔和灰绿；信号绿只承担居中信号轨、重点和表格标签。不要矩阵雨、发光描边、伪 HUD 或闪烁光标。
Outline 映射
| Source | Page |
|---|---|
* 一级标题 |
独占 emphasis 章节页 |
** 及更深标题 |
独占 title 页；深度越高字号越低 |
| 段落 | theme 文本页；仅在必要时物理拆页 |
| 列表 | 同层级连续 3–4 项优先整组同页；更长列表切成 3–4 项一页且避免单项尾页 |
| 表格 | table 页；超过 6 行分页并重复表头 |
| 引用 | quote 页；超过 2 个原始行时续页并记录 sourceParts |
#+begin_example / fenced code |
pre 页，逐字符保留 |
*强调* / ~code~ / =verbatim= |
hl: true；emphasis 页忽略 inline hl |
多行不是统一降字号
多行页同时看「行数」和「文本密度」，但始终使用单列 rows：
- 2、3、4 行全部沿页面中轴纵向排列，不在翻页时切换左右阅读路径。
- 字号由「行数 + light/medium/dense」复合规则决定；先拆页、再放大，最后才由 fit guard 微调。
- 单行、非列表、非整行公式且去空白后
≤16个字形的内容先判为「语义原子」：即使 CJK 权重落入 long，也整句单行并进入高桥流。 - 连续同层级列表先保语义块：3–4 项整组同页；超过 4 项时切成 3–4 项，并避免把最后一项单独遗留。
- 网格项必须
min-width: 0，正文自然换行；不要把.line设成 flex/grid，以免拆散高亮与公式。 - 单行 single/short/medium 使用「高桥流」：少字就是主视觉，横屏有效字号以
≥90px为目标。
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 12d ago First seen · 205 lines · 144 tokens per session scan A 3101e6725c5e
ljg-present is a skill published in the GitHub repository lijigang/ljg-skills (7,340 stars, last pushed 3d ago), licensed MIT. It adds 144 tokens to every session and 3,777 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
