Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

app 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 today.

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.

技术栈与风格

  • TypeScript + React Hooks;优先函数组件,避免 class 组件。
  • 组件 Props 使用 interface 显式声明,避免 any
  • 遵循仓库既有格式与 Prettier 配置;改动保持最小范围,不重写无关模块。
  • 不臆测接口或业务逻辑;上下文不足时说明缺口或反问。
  • 类型收窄优先使用原生接口:用 Array.isArray 代替 _.isArray,用 typeof x === 'number' 代替 _.isNumber,用 x == null 代替 _.isNil,以此类推。lodash 的类型守卫函数在缺少 @types/lodash 时不会被 TypeScript 识别为类型守卫,导致 unknown 类型无法收窄。

数据与错误

  • 异步请求须有错误处理(try/catch.catchonError 等,与现有模式一致)。

折叠面板与表单

  • antdCollapse.Panel 初始折叠时不会挂载内容。面板内包含需要参与校验、回填或提交的 Form.Item / Form.List 时,必须添加 forceRender,确保字段注册到 Form;仅用于展示的内容不需要添加。

样式与颜色

  • 颜色、主题相关值使用 src/theme/variable.css(及现有主题体系)中的变量,避免魔法色值。
  • Tailwind 与 Less 的分工、反模式与迁移方式.cursor/rules/tailwind-usage.mdc(匹配 src/**/*.{ts,tsx,less,css} 时自动注入)。

测试

  • 使用 Vitest + Testing Library。
  • 测试文件命名:*.test.ts / *.test.tsx*.spec.ts / *.spec.tsx,与待测文件同目录或约定目录即可。
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.
