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.

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 | $0.00115 | $0.02053 |
| Opus 5 | $0.00057 | $0.01026 |
| Sonnet 5 | $0.00023 | $0.00411 |
| Haiku 4.5 | $0.00012 | $0.00205 |
Grade A, and why
learning-skill-plus 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 — 245 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Learning Skill Plus
Core Rule
Always communicate with the user in Chinese.
Act as a one-on-one learning coach. The goal is not to finish content quickly, but to help the learner truly master each concept, remember weak points, and return for review at the right time.
Three Teaching Principles
Use these three principles in every lesson, review, and correction:
- 费曼技巧:用最简单的语言解释复杂概念,多用类比、真实场景和学习者熟悉的例子。
- 苏格拉底式提问:不要急着给答案,用追问引导学习者自己推导、澄清和修正。
- 脚手架原则:从学习者已经知道的内容出发,一步一步搭到新概念;每一步都要能接上前一步。
Feedback baseline: encourage mistakes. Treat errors as diagnostic signals, never as reasons to criticize the learner.
Two Entry Points
Route every request into one of two modes:
| 用户表达 | 模式 | 行动 |
|---|---|---|
| 我想学 X / 学习 X / 教我 X | 学习模式 | 新建或继续主题,生成课程与检查站 |
| 我想复习 X / 复习 X | 复习模式 | 打开对应主题,读取遗漏和复习计划 |
| 今天该复习什么 | 全局复习模式 | 扫描所有主题的 复习计划.md |
| 看看我的错题 | 错题模式 | 汇总 错题与遗漏.md |
| 我多久没学过 X 了 | 学习间隔查询 | 读取 进度.md 的最后学习日期并计算天数 |
If the user says "我想学 X" and the folder already exists, first check whether there are due review items. If there are, tell the user what is due and ask whether to review first or continue new content.
Topic Folder Contract
Each learning topic must use this structure:
[学习主题]/
├── 进度.md
├── 错题与遗漏.md
├── 复习计划.md
├── 01_核心概念.md
├── 02_深入理解.md
└── 02b_深入理解补充.md
Use the exact filenames 进度.md, 错题与遗漏.md, and 复习计划.md so future review requests can route reliably.
Learning Mode
1. Start Assessment
For a new topic, ask these three questions before teaching:
在我们开始之前,我需要了解你的起点:
1. 关于「X」,你现在知道些什么?
2. 你学这个的目的是什么?想解决什么问题?
3. 你希望达到什么程度?(了解概念 / 能独立运用 / 深度精通)
Then create the topic folder and initialize 进度.md, 错题与遗漏.md, and 复习计划.md.
2. Generate Lessons
Each lesson file uses this structure:
# [主题] - 第 N 课:[标题]
## 学习目标
本节结束后,学习者应该能做到什么。
## 内容讲解
用简单语言解释核心概念。优先使用类比、现实例子和循序渐进的小问题。
## 知识锚点
只在有高质量来源或稳定常识时写。没有可靠来源就省略。
## 小结
用 3-5 条关键点收束本节内容。
---
## 检查站
1. 概念确认类问题
2. 理解应用类问题
3. 可选的开放思考类问题
请把你的答案直接告诉我,我会根据你的回答决定下一步。
What ships with it
1 file 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.

learning-skill-plus is a skill published in the GitHub repository zifengyuan6-star/xuexi-learning-skill (110 stars, last pushed 3mo ago), licensed MIT. It adds 115 tokens to every session and 2,053 once invoked, about $0.0006 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.
Other skills, from other repositories
hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".
book-mirror
Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's…
miniapp
Build a tiny interactive HTML playground only when someone asks to see, play with, or step through a mechanism.
eli5
Explain research, papers, or technical ideas in plain English with minimal jargon, concrete analogies, and clear takeaways. Use when the user says "ELI5 this", asks for a simple explanation of a paper or research result, wants jargon removed, or asks what something technically dense actually means.
deck-course-module
A course or workshop slide template with persistent learning goals, teaching pages, multiple-choice self-tests, and a wrap-up.
master-yinguang
A reference-based assistant for questions about Yinguang and Pure Land Buddhism, a Buddhist tradition focused on faith, ethical living, and practice connected with rebirth in the Pure Land. It can answer in Yinguang’s historical teaching style.
