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 | $0.01466 | $0.01466 |
| Opus 5 | $0.00733 | $0.00733 |
| Sonnet 5 | $0.00293 | $0.00293 |
| Haiku 4.5 | $0.00147 | $0.00147 |
Grade A, and why
xiaochen-skills CLAUDE.md 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
项目概览
这是一个 Claude Code 插件市场仓库(Plugin Marketplace),里面是一组 cyxj-* skill,通过
/plugin marketplace add chenyuxiaojin/xiaochen-skills 安装到 Claude Code。
真相源 = .claude-plugin/marketplace.json。判断"有几个/哪些插件、各自路径"时一律以它为准,
不要相信任何文档里写死的数字(它们会漂移)。plugins/ 下的目录数 ≥ marketplace 注册数:
没注册进 marketplace 的插件,用户装不到(这通常是遗漏,不是设计)。
架构
.claude-plugin/marketplace.json ← 插件市场注册表(所有插件的入口,新插件必须在此注册)
plugins/
cyxj-{name}/
skills/
cyxj-{name}/ ← 技能文件夹名 = 插件名 = SKILL.md 的 name,三者必须一致
SKILL.md ← Skill 核心:frontmatter(name/description) + 指令,运行时被读取
*.py / scripts/* ← 辅助脚本(直接放 SKILL.md 同级,或放 scripts/ 子目录,仓库里两种都有)
*.css / *.html ← 静态资源(如 wechat-pub 的排版模板)
references/ templates/ ← 参考素材 / 模板(部分 skill 有)
两类 skill:
- 纯指令型(obsidian-build、roundtable、jingxuan、transcript 等)—— 没有脚本,全靠 SKILL.md 的 frontmatter + 正文指令(部分配 references/ 模板)驱动;roundtable 还会现场拉起多个 Opus subagent 扮演不同角色
- 脚本型—— SKILL.md 调用同目录的 Python/Bash 脚本,脚本里用
${CLAUDE_PLUGIN_ROOT}(或$SKILL_DIR) 拼本地路径定位资源。新写脚本引用本地文件时必须走这个变量,不能写死绝对路径
description frontmatter 不只是说明文字——它定义了 skill 的触发条件(含触发词),写得准不准直接决定
Claude Code 会不会在对应场景自动唤起这个 skill。
命名规则(三处必须完全一致)
插件目录名、技能文件夹名、SKILL.md 的 name 字段,三处全等,格式 cyxj-{短名}:
plugins/cyxj-foo/skills/cyxj-foo/SKILL.md ← name: cyxj-foo
.claude-plugin/marketplace.json ← "name": "cyxj-foo", "source": "./plugins/cyxj-foo"
例外:多 skill 插件(目前有 cyxj-video-doctor(cyxj-content + cyxj-hook)和
cyxj-image-studio(cyxj-poster + cyxj-video-cover)两个)。
此时插件名不等于技能名,但每个技能文件夹名仍必须 = 其 SKILL.md 的 name;插件级共享资源放
plugins/{插件}/references/(文档)或 plugins/{插件}/lib/(Python 模块,脚本里按
Path(__file__).resolve().parents[3] / "lib" 定位),skill 里用 ${CLAUDE_PLUGIN_ROOT}/... 引用。
只有需要共享文件的强关联 skill 才合并进同一插件,不要为省注册条目乱合。
改 Skill 后的同步检查清单
文档与注册表极易漂移(本仓库历史上多次出现)。任何对 skill 的改动(增 / 删 / 改名 / 改内容)做完都要逐项核对:
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.
- 10d ago First seen · 84 lines · 1,466 tokens per session scan A 46dc0386a10c
xiaochen-skills CLAUDE.md is an instructions file published in the GitHub repository chenyuxiaojin/xiaochen-skills (6 stars, last pushed 5d ago), licensed MIT. It adds 1,466 tokens to every session, about $0.0073 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 2026-08-31.
