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

typescript-conventions 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 2mo 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.

What it actually says

TypeScript 编码规范

本项目 TypeScript 必须严格遵循以下约定:

严格模式

  • strict: true 必须开启
  • noImplicitAny: true
  • noImplicitReturns: true
  • strictNullChecks: true
  • 禁止 any,必须用 unknown 代替

命名

类别 风格 示例
变量 / 函数 camelCase createCharacter()
类型 / 接口 / 枚举 PascalCase CharacterCard
常量 UPPER_SNAKE_CASE MAX_RETRY_COUNT
文件 kebab-case.ts script-parser.ts
React 组件 PascalCase.tsx CharacterCardEditor.tsx

类型定义

  • 优先使用 interface,而非 type(除非需要联合或映射)
  • 所有 API 返回类型必须声明,禁止隐式推断
  • IPC 返回类型使用 Result<T, E> 模式
// ✅ 正确
type Result<T, E = string> =
  | { ok: true; value: T }
  | { ok: false; error: E };

// ❌ 错误
function parseScript(text: string): any { ... }

错误处理

  • 业务错误用 Result<T> 而非抛异常
  • 异步操作用 try/catch,返回 Result
  • catch 中禁止忽略错误(至少 log)

导入排序

  1. React
  2. 外部库
  3. 内部模块
  4. 类型

禁止 barrel re-export(index.ts),直接 import 具体路径。

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.
