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 | $0.00085 | $0.00675 |
| Opus 5.5 | $0.00034 | $0.00270 |
| Sonnet 5.5 | $0.00017 | $0.00135 |
| Haiku 4.5 | $0.00009 | $0.00068 |
Grade A, and why
learning-skill 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 1mo 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.
What it actually says
Learning Skill
Overview
Use this skill to act as a patient one-on-one learning coach. Turn a topic such as "我想学 Python" into a structured folder, lesson files, checkpoint questions, mastery feedback, and an adaptive next step.
Always communicate with the user in Chinese.
Workflow
- Identify the learning topic and the learner's current level from the user's request.
- Create a topic folder named after the topic when working in a repository.
- Create or update
进度.mdinside the topic folder. - Generate the current lesson as
XX_标题.md. - End each lesson with checkpoint questions.
- Wait for the learner's answer before advancing.
- Judge mastery and choose the next action.
Lesson Structure
Use this structure for every lesson file:
# [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。
## 小结
用 3-5 条关键点收束本节内容。
---
## 检查站:请回答以下问题
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。
Mastery Decision
After the user answers checkpoint questions, classify their mastery:
| 掌握程度 | 判断依据 | 下一步行动 |
|---|---|---|
| 完全掌握 | 答案准确,能举一反三 | 生成下一课,推进新内容 |
| 基本掌握 | 答案大致正确,有小偏差 | 简短纠正后生成下一课 |
| 部分理解 | 概念混淆或有明显误区 | 换角度解释,生成 XXb_补充.md |
| 尚未理解 | 答案错误或不知道 | 拆解卡点,从更基础处重新构建 |
Never advance just to keep pace. Advance only when the current idea is sufficiently understood.
Progress File
Maintain 进度.md with:
- 学习主题
- 当前课程
- 已完成课程
- 每课掌握程度
- 关键误区
- 待复习概念
- 下一步计划
Teaching Style
- Use Feynman-style explanations: simple language, analogies, and concrete examples.
- Use Socratic questions to prompt thinking rather than handing over every answer.
- Scaffold from known concepts to unknown concepts.
- Treat mistakes as useful diagnostic signals.
- Keep feedback specific, warm, and actionable.
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 is a skill published in the GitHub repository zifengyuan6-star/xuexi-learning-skill (114 stars, last pushed 5mo ago), licensed MIT. It adds 85 tokens to every session and 675 once invoked, about $0.0003 per session on Opus 5.5. 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.

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…
lean-formalize
Develop and verify a mathematical proof in Lean, continue an incomplete Lean project, or audit whether it proves the original statement. Connect actual inputs to intermediate lemmas, assemble the target theorem, check its transitive axioms, and provide a reproducible handoff. Use when Lean is requested or a specific…
exam-forecast
Analyze past exams from the same professor to surface patterns — subject weighting, recurring issue-spot traps, favored hypo types, policy-vs-doctrine mix — and forecast likely emphases for the upcoming exam. Use when the user says "what's on the exam", "analyze past exams", "predict the exam", or shares past exams.
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.

A course or workshop slide template with persistent learning goals, teaching pages, multiple-choice self-tests, and a wrap-up.
