coding-session-to-tutorial

coding-session-to-tutorial is a skill for Claude Code, Codex from chengkj99/kj-skills. It costs 132 tokens per session (1,601 once invoked), scanned A, original, MIT.

A writing-to-image tool that creates simple SVG diagrams from descriptions, finds places in articles or courses where a diagram would help, or fills image placeholders. SVG is a text-based image format that stays sharp when resized.

In plain words
What is it for?
Use it to generate SVG flowcharts or comparison diagrams, analyze content for useful illustration points, or replace placeholders such as `[流程图]` with generated images. It is not intended for photorealistic or AI-styled illustrations.
Why use it?
It helps turn explanations into diagrams when a visual can communicate the relationships faster than paragraphs. It also provides a repeatable format and process for adding those diagrams to course material.

Token cost

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.

Security

Grade A, and why

coding-session-to-tutorial 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 6d 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.

实战案例转教程

把一段原始的实战记录(可以很乱、很碎、有弯路)转化为其他程序员可以直接学习和复用的教程。

这个技能的核心价值:你解决问题用了 1 小时,教程让下一个人 10 分钟搞定。


执行流程(每次必走)

第 1 步:读取和整理输入

接受以下任意形式的输入:

  • 终端命令和输出(粘贴即可,不需要整理)
  • 一段对话描述(「我先试了 A,不行,然后试了 B,还是不行,最后用 C 解决了」)
  • 截图描述(「截图里显示的是 xxx 报错」)
  • 多种形式混合

不要催用户整理输入。你来整理。

从输入中提取:

  1. 问题是什么(现象 + 报错/数据)
  2. 初步假设是什么(用户当时以为是什么原因)
  3. 尝试过哪些方法(包括走过的弯路)
  4. 最终解法
  5. 有没有预防/验证步骤

只提取素材明确支持的事实。不得为了补齐叙事而推测用户的初步假设、弯路、AI 分析过程、耗时、次数或最终结果。素材未提供的字段标记为“未提供 / 待确认”,或在不影响教程成立时省略。

如果信息明显不够(不知道问题是什么,或不知道最终怎么解决的),只问 1 个最关键的缺失问题,不要问多个。


第 2 步:确认教程定位

在开始写之前,向用户确认一件事(简短即可):

「这篇教程准备放在哪里?」

  • A. 公众号文章(更偏叙事,情感节奏)
  • B. 个人网站/Wiki(完整技术记录,干货为主)
  • C. 内部沉淀(团队内部,注重可复用性)

不同定位影响叙事详细程度,但结构一致。如果用户没有明确偏好,默认 B(完整技术记录)


第 3 步:按模板生成教程初稿

引用 references/tutorial-template.md,生成完整的教程初稿。

强制要求

  1. 初步假设有证据才写:用户说过或日志能支持时,忠实保留;没有就不补造。
  2. 真实弯路必须保留:素材里确实发生过的失败尝试不能删;素材没有弯路时,不得为了故事性强行添加。
  3. AI 协作方式按证据写:只记录素材能确认的“给了什么 → AI 怎么分析 → 实际结果”;不完整就标注缺口,不代替用户回忆。
  4. 通用清单必须用 checkbox + 命令块格式,不能写叙述句
  5. 方法论要升维,从「这次的步骤」升到「下次遇到类似问题的思维框架」

第 4 步:质量自检

生成初稿后,对照 references/writing-principles.md 里的「常见错误清单」过一遍:

[ ] 素材若包含弯路,是否完整保留;素材若不包含,是否没有强行补造
[ ] AI 协作部分是否只写了证据支持的「给了什么 → AI 怎么分析 → 实际结果」
[ ] 通用清单里是否有分支(情况 A / 情况 B)而不是只有一条路
[ ] 方法论是否升维了(不是步骤复述,是可迁移思维框架)
[ ] 所有命令是否都在代码块里
[ ] 时间、大小、次数等具体数字是否全部来自素材;没有数据时是否保守表述或标记待补充
[ ] 是否无虚构的第一人称经历、报错、对话、命令、用户反馈或验证结果

有不符合的,直接修改初稿,不要列出来问用户。


第 5 步:输出 + 后续推荐

输出完整教程初稿后,附一段简短的后续建议:

---
📌 后续建议:

这篇教程初稿已经可以发布。如需进一步加工:

- 想提升文章的「人味」和传播力 → 用 kangjian-skill 做风格润色
- 想生成配套的短视频脚本 → 用 content-creator 工作流 D
- 想拆解成小红书笔记 → 用 content-creator 工作流 F
- 想直接发公众号 → 用 baoyu-post-to-wechat

如果这篇内容还需要一个更好的「内容角度」定位(比如想做成系列),可以把这篇初稿交给 ai-programming-topic-planner 来规划角度。

输出格式规范

标题格式# AI 编程实战:[问题动词短语] 导言格式> [一句话定位] 代码块:全部用 ```bash ``` 或对应语言标注 checkbox 清单:全用 - [ ] 格式 阶段标题:有耗时记录时用 ### 第 N 阶段:[名称](约 X 分钟);无记录时用 ### 第 N 阶段:[名称],不补造时间。


判断是否需要补充信息

以下情况需要主动问用户(只问最关键的那一个):

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.

Changes

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.

coding-session-to-tutorial is a skill published in the GitHub repository chengkj99/kj-skills (14 stars, last pushed 5d ago), licensed MIT. It adds 132 tokens to every session and 1,601 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.
