What it does

Book2skill is an agent skill from HHU3637kr/skills. Distill a book into a coherent set of executable skills. Use when the user asks to "拆书" / "蒸馏一本书" / "把 XX 书做成 skill" / "turn a book into skills" / "book2skill" — i.e. wants a book's frameworks, principles, and methodologies extracted into atomic, reusable Claude skills that an agent can invoke in real-world situations. NOT for simple summarization, book reviews, or role-playing as the author (that is nuwa-skill's job).

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 20 other files, including reference files (for example `references/extractors/case-extractor.md`, `references/extractors/counter-example-extractor.md` and `references/extractors/framework-extractor.md`).

It sits in Writing & Content, covering Summarization and Subagents.

When your agent uses it

  • The user asks to 拆书 / 蒸馏一本书 / 把 XX 书做成 skill / turn a book into skills / book2skill — i.e
  • Tasks that involve Summarization
  • Tasks that involve Subagents

Example prompts

  • “把 XX 书做成 skill”
  • “turn a book into skills”
  • “book2skill”
  • “/book2skill”

Workflow steps

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

  1. 书的文本来源: PDF / EPUB / TXT 文件路径, 或可访问的纯文本。不要在没有文本的情况下"凭记忆"拆书 — 宁可停下来问用户要。
  2. 书名 + 作者 + 出版年: 用于目录命名和审计。
  3. 是否首次试点: 如果用户是第一次用 book2skill,建议先拆 1 本验证流程再批量。

What it can do on your machine

Read from SKILL.md and the folder at commit a2cccf6. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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

Book2skill loads about 1.1k tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 108 tokens; SKILL.md has 344 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~108
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~11k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 344 words (~1,106 tokens).
