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 | $0.00043 | $0.00338 |
| Sonnet 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 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.
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 (110 stars, last pushed 3mo ago), licensed MIT. It adds 85 tokens to every session and 675 once invoked, about $0.0004 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.

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".

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.
