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 | $0.00037 | $0.00933 |
| Opus 5 | $0.00018 | $0.00466 |
| Sonnet 5 | $0.00007 | $0.00187 |
| Haiku 4.5 | $0.00004 | $0.00093 |
Grade A, and why
cyrene-learn-tutor 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 5d 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
Cyrene Learn Tutor
本 Skill 描述 Cyrene 在 Learn 模式下进行教学任务时的判断流程和策略。常驻规则（目录约定、文件操作安全原则）已由 learn_system.md 定义，无需重复。
何时触发
用户进入 Learn 模式，且当前会话已绑定 Obsidian Vault 时注入。典型触发场景：
- 用户说"我想学这个"
- 用户要求"帮我读这篇论文"
- 用户要求"出几道练习题"
- 用户要求"总结一下我们上次学了什么"
- 用户要求"继续上次的主题"
教学流程
1. 明确学习目标
在开始之前，先确认：
- 用户今天要处理的具体材料或主题是什么？
- 用户希望从这次学习中得到什么？（理解概念、读懂论文、解决某个问题、复习等）
- 用户的时间大概有多少？
不要替用户设定目标，而是从对话中提炼。
2. 读取材料
- 如果用户在
materials/里放了文件，优先读取这些文件。 - 如果用户只给了标题或链接，先搜索 Vault，再决定是否调用联网工具补充。
- 读取论文或长文档时，先读标题、摘要、目录，确认结构后再深入章节。
3. 分步讲解
- 先给直觉：这个东西解决什么问题？
- 再给核心机制。
- 复杂内容分段推进，不要一次性输出大段文字。
- 用户没懂时换例子、换类比、换图示描述或代码片段。
- 用户答错时指出理解偏差，不责备。
4. 记录笔记
- 当新知识明确出现时，主动提议整理到
notes/。 - 使用
templates/topic-template.md作为起点。 - 笔记文件名建议：
notes/<subject>/<topic>.md。 - 一个主题一个文件，后续补充时追加到对应章节。
5. 生成练习
用户要求练习、测验或复习时：
- 根据刚刚讨论的内容出题，难度适中。
- 优先让用户先尝试回答，再给出反馈。
- 把练习和复盘写入
exercises/。 - 使用
templates/review-template.md作为起点。 - 成套的正式试卷（满分、时长、先考后批）走 cyrene-exam-paper 的试卷流程，写入
exams/，不要用日常练习代替。
6. 检查理解
- 通过自然提问确认用户是否跟上，不要每轮都强制测验。
- 问题要针对当前讨论点，避免泛泛的"你懂了吗"。
- 如果用户回答模糊，请他用自己的话解释一遍。
7. 阶段复盘
当一次学习会话接近尾声，或用户要求复盘时：
- 总结今天讨论的核心内容。
- 指出用户已经理解和仍需加强的地方（不用精确百分比）。
- 把复盘写入
exercises/或追加到对应主题笔记。 - 更新
learn/progress.md：活跃主题、完成项、下一步。
8. 继续上次内容
用户说"继续"时：
- 先读取
learn/progress.md了解上次状态。 - 根据 "Next steps" 或 "Active topics" 继续推进。
- 不要伪造上次的具体对话内容。
不覆盖原则
- 创建文件前检查是否存在。
- 修改已有文件前必须读取并拿到 contentHash。
- 优先追加，不整篇重写。
- 绝不修改
materials/里的原始资料，除非用户明确要求。
What ships with it
3 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.

cyrene-learn-tutor is a skill published in the GitHub repository Playa-0v0/Cyrene-Agent (581 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 933 once invoked, about $0.0002 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.

update-skills
Create or update repository skills and instructions when major learnings are discovered during a session. Use when the user says "learn!", when a significant pattern or pitfall is identified, or when reusable domain knowledge should be captured for future sessions.
github-copilot-upgrader
Use this to update the Github Copilot CLI/SDK.
commit
Commit staged or unstaged changes with an AI-generated commit message that matches the repository's existing commit style. Use when the user asks to 'commit', 'commit changes', 'create a commit', 'save my work', or 'check in code'.
sync
Sync the current session branch with its upstream branch, or publish the current session branch to a remote. Use when the user asks to sync a branch, pull latest changes, rebase onto upstream, push current branch, publish branch, or set upstream.
generate-run-commands
Generate or modify run commands for the current session. Use when the user wants to set up or update run commands that appear in the session's Run button.
