world-book-skillCreate and manage SillyTavern Character Cards (角色卡) and World Books (世界书).
World Book Skill is an agent skill from echo-xianyu/worldbook-skill. Create and manage SillyTavern Character Cards (角色卡) and World Books (世界书). Supports character card writing, world book creation, MVU ZOD variables, HTML beautification, opening scene writing, and card-generator.py integration. 支持角色卡编写、世界书创建、MVU ZOD 变量系统、HTML 前端美化、开场白创作、 card-generator.py 集成等多种场景。使用前先读取场景路由器和对应参考文件。
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 20 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/card-generator-guide.md` and `references/character-card-guide.md`).
It sits in Frontend & Design, covering Forms and validation. It works with Zod. The repository describes itself as: A skill for Agent to write Worldbook for SillyTavern.
9 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit e8501ea. It shows what the files ask for, not the result of running them.
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.
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
World Book Skill loads about 1.8k tokens when it runs, and up to ~57k if it reads all its reference files. Until then it costs about 83 tokens; SKILL.md has 481 words of instructions outside code blocks.
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.
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); the scripts in this folder are not scanned.
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 481 words (~1,787 tokens).
SKILL.md and 17 other files (scripts, references) in world-book-skill of echo-xianyu/worldbook-skill.

Create and manage SillyTavern Character Cards (角色卡) and World Books (世界书). World Book Skill is an agent skill from echo-xianyu/worldbook-skill. Create and manage SillyTavern Character Cards (角色卡) and World Books (世界书).
World Book Skill fits situations like: tasks that involve Forms and validation.
Run `npx skills add echo-xianyu/worldbook-skill --skill world-book-skill -a claude-code`. Or copy the skill folder (world-book-skill in echo-xianyu/worldbook-skill) into .claude/skills/world-book-skill in your project. Claude Code loads it when a task matches its description.
Run `npx skills add echo-xianyu/worldbook-skill --skill world-book-skill -a codex`. Or copy the skill folder (world-book-skill in echo-xianyu/worldbook-skill) into .agents/skills/world-book-skill in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add echo-xianyu/worldbook-skill --skill world-book-skill -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/world-book-skill, .gemini/skills/world-book-skill, .github/skills/world-book-skill and .opencode/skills/world-book-skill in your project.
Going by SKILL.md and its folder, World Book Skill needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
World Book Skill has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 1.8k tokens (SKILL.md is roughly 7.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 55k tokens, read only when the agent opens those files.
