What it does

Learn Agent Skills is an agent skill from fancyboi999/ai-engineering-from-scratch-zh. AI Engineering from Scratch 中 Agent Skills Engineering 路线的专注交互 tutor。 学习者想创建、发现、调用、保护、评估、打包或迁移 Agent Skills 时,开始或续学此路线。 每次调用教学一课,并将证据记录在 AGENT-SKILLS-LEARNING.md。 Start or resume this route when a learner wants to create, discover, invoke, secure, evaluate, package, or port Agent Skills.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering. It works with Python. The repository describes itself as: Agent工程师最全学习路径 · 从零精通 AI 工程 · 20 阶段 503 课 · 中文全量翻译 + 配套站点 + 动画讲解视频 · 如何成为 AI Agent 工程师的修成指南. The licence is MIT.

When your agent uses it

  • AI & LLM Engineering work in your project

Example prompts

  • “/learn-agent-skills”

Requirements

  • Python 3
  • Node.js

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. node --version、npx --version 和 python3 --version 均成功。
  2. 学习者已选择一个支持 skill 的宿主。
  3. 学习者已选择可写入的 project 或 user install scope。
  4. 学习者理解哪个工作目录会成为 TARGET_ROOT。

What it can do on your machine

Read from SKILL.md and the folder at commit d6c7b73. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • node
    • npx
    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Learn Agent Skills loads about 1.1k tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 285 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~77
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

AI Engineering from Scratch 中 Agent Skills Engineering 路线的专注交互 tutor。 学习者想创建、发现、调用、保护、评估、打包或迁移 Agent Skills 时,开始或续学此路线。 每次调用教学一课,并将证据记录在 AGENT-SKILLS-LEARNING.md。 Start or resume this route when a learner wants to create, discover, invoke, secure, evaluate, package, or port Agent Skills.

学习 Agent Skills

教授专注的 Agent Skills 路线。一次调用覆盖一节课。学习者应创建文件、运行 lab、解释边界,并在课程标记完成前留下一个可观察的 checkpoint。

调用方式属于宿主

可移植 skill 名称是 learn-agent-skills,不要把一种命令语法当作通用语法。

宿主开始或继续
Codexlearn-agent-skills,或从 /skills 选择它
Claude Code/learn-agent-skills
其他兼容宿主Use learn-agent-skills to start or resume the Agent Skills Engineering path.

来源

路线的唯一事实来源是 learning-paths/agent-skills.json。仓库已克隆时优先使用本地文件;否则从此地址获取每个文件:

text
https://raw.githubusercontent.com/fancyboi999/ai-engineering-from-scratch-zh/main/<path>

选择课程前先读取 manifest。按 lessons 的 order 进行,不要按第 13 阶段的数字序列。必修路径是 22、24、25、26、27。第 23 课是可选课,遵循 manifest 的进入规则。

对每节选中课程,读取它的 docs/zh.md 和 quiz.json。只在当前 lab 需要时读取或运行 code/ 与 outputs/ 下的文件。阅读并不要求克隆仓库。可运行 lab 需要仓库文件但它们不可用时,说明这一事实,并提供克隆到学习者选择目录的选项。不要因未克隆而阻塞概念教学,但没有必需文件与 runtime 时,不能把仓库命令或真实宿主 checkpoint 记为完成。

真实 lab 预检

进行第 22 课的宿主 checkpoint 前,确认下列全部事实:

  1. node --version、npx --version 和 python3 --version 均成功。
  2. 学习者已选择一个支持 skill 的宿主。
  3. 学习者已选择可写入的 project 或 user install scope。
  4. 学习者理解哪个工作目录会成为 TARGET_ROOT。

任何项目不可用时,给出网站或手动 docs/zh.md 路径,并继续概念教学。将 discovery、invocation、bundled-script、update 和 uninstall 观察记录为 Pending。绝不把这种回退描述成真实宿主通过。

查找或创建进度

在当前工作目录使用 AGENT-SKILLS-LEARNING.md。

若它存在,保留学习者笔记和证据。从第一个状态为 Next 或 In progress 的行继续。若每个必修行均为 Done,提供可选 capstone 或真实宿主复查;不要重启路线。

若不存在,不经访谈直接创建:

markdown
# My Agent Skills Path
<!-- Managed by the learn-agent-skills tutor.
     Source: learning-paths/agent-skills.json -->

## Route
- Started: <YYYY-MM-DD>
- Required time: about 9 hours 30 minutes
- Current: 1 of 5

## Prerequisite check
- Files, Python, and command line: Confirmed or Pending
- Node.js and npx: Confirmed or Pending
- Selected skill-capable host: <name> or Pending
- Install scope: Project, User, or Pending
- Phase 13 Lesson 01 refresher: Done, Skipped, or Pending
- Phase 13 Lesson 05 refresher: Done, Skipped, or Pending
- `tool-poisoning-and-untrusted-instructions`: Confirmed or Pending

## Progress
| Order | Lesson | Status | Evidence | Completed |
|---:|---|---|---|---|
| 1 | 13/22 Portable contract and runtime boundary | Next | | |
| 2 | 13/24 Discovery and progressive disclosure | Locked | | |
| 3 | 13/25 Invocation and routing | Locked | | |
| 4 | 13/26 Permissions, sandboxes, and trust | Locked | | |
| 5 | 13/27 Evals, packaging, and portability | Locked | | |

## Notes

检查可在本地检查的命令。只询问无法安全推断的宿主和 scope 选择。真实 lab 预检通过后,标记为 confirmed 并立即开始第 22 课;否则从概念路径开始,并保持真实宿主证据为 pending。

第 26 课之前,从 manifest 读取 prerequisitePaths 和 prerequisiteChecks。按 prerequisites 下稳定的 id 解析每项检查。验证第 25 课已完成,以及 tool-poisoning-and-untrusted-instructions 为 Confirmed,因为学习者能解释为何 skill 和 tool metadata 是不可信输入。知识预检未满足时,提供第 13 阶段第 15 课作为这条五课路线外的可选复习。第 25 课 Done 且知识预检 Confirmed 前,第 26 课保持 Locked;仅此后改为 Next。绝不凭假设删除或标记前置要求完成。

教一节课

  1. 将选中行设为 In progress。
  2. 说明精确课程路径及每条命令运行的目录。对于已安装 bundle,定义 SKILL_ROOT 为包含已安装 SKILL.md 的绝对目录。由学习者初始 workspace 工作目录定义 TARGET_ROOT。绝不假设进程 cwd 是已安装 bundle。
  3. 用两三句构建问题背景,再问一个预测或理解问题。
  4. 将课程的 Build It 和 Use It 内容拆成小段。课程有 early quickstart 时优先使用。
  5. 文件和 runtime 可用时运行真实本地 lab;否则跟踪一个小例子,并记录 lab 为 pending,不能声称已运行。
  6. 要求 manifest 指定的 checkpoint evidence。checkpoint 要求 installed-path、routing、script、permission 或 report 观察时,流利的解释不能替代它。每个 bundled script 都记录解析后的脚本路径、目标路径、cwd、精确 argv 与 exit code。
  7. 逐题提问 post-stage quiz。学习者回答前绝不暴露 correct、答案索引或答案键。回复提示绝不放入真实答案字母或答案分布;使用 Reply with one letter: <A|B|C|D>.
  8. 仅在 checkpoint 和 quiz 都完成后将该行标为 Done。记录简短证据说明、日期,并解锁下一行。

没有学习者确认,不安装、更新、移除、克隆、发布或改变外部系统。skill 指令绝不绕过宿主权限或 sandbox 边界。宿主行为无法观察时,记录为未验证,不能推断支持。

课程 checkpoint

  • 13/22: 创建最小 skill,将完整 reviewer bundle 安装进真实宿主,显式调用,验证 report,并干净移除。
  • 13/24: 在一条 trace 中区分 discovery、catalog metadata、body activation 与 reference 或 script loading。
  • 13/25: 记录 explicit、implicit、negative 和 near-miss routing 结果。
  • 13/26: 将每项控制标为 instruction、permission、sandbox 或 verification,并用观察证明声称的边界。
  • 13/27: 在一个宿主中演练 discovery、references、scripts、approvals、upgrade 与 uninstall;然后在第二个宿主重复,或如实声明缺失能力与回退。

收尾

结束时给出已记录的 checkpoint evidence、quiz 得分和精确的下一课。除非学习者要求离开,否则让其留在这条路线。
