What is Claude-Code-Mailer CLAUDE.md?

A set of project instructions for Claude Code Mailer, a software project that sends multilingual emails. It requires English, Simplified Chinese, and Hong Kong Traditional Chinese documentation and templates to stay aligned.

Use it when changing README files, email templates, configuration settings, language support, or related mailer code.

It helps prevent one language version or configuration file from falling out of sync with the others. This reduces inconsistent documentation and email templates.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02047	$0.02047
Opus 5	$0.01024	$0.01024
Sonnet 5	$0.00409	$0.00409
Haiku 4.5	$0.00205	$0.00205

Security

Grade A, and why

Claude-Code-Mailer 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 8d 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.

Claude Code Mailer Project - 多语言项目管理规则

项目语言支持

本项目支持三种语言，所有修改必须同步到所有语言版本：

zh-CN - 简体中文
zh-HK - 繁体中文（香港）
en - English

文档同步规则

README 文件

README.md - 英文文档
README.zh.md - 中文文档
两个文件内容必须保持同步，只是语言不同

模板文件同步

config/templates.zh-CN.yaml - 简体中文邮件模板
config/templates.zh-HK.yaml - 繁体中文邮件模板
config/templates.en.yaml - 英文邮件模板
所有模板文件结构必须保持一致（相同的 events 和 variables）

配置文件同步

.env.template - 注释需要同时支持中英文理解
确保所有语言版本的配置项一致

修改检查清单

在进行任何修改时，请按以下清单检查：

📋 文档修改

更新 README.md (英文)
更新 README.zh.md (中文)
确保两个文档内容一致
更新项目结构说明（如有新增文件）

📋 模板修改

修改 templates.zh-CN.yaml
修改 templates.zh-HK.yaml
修改 templates.en.yaml
确保所有模板结构一致
测试模板渲染功能

📋 配置修改

更新 .env.template
更新 README 中的配置说明
确保注释清晰易懂

📋 代码修改

如需支持新语言，更新 mailer.js 中的语言检测逻辑
更新相关文档中的语言列表
测试新语言功能

新语言添加流程

如需添加新语言支持：

创建新的模板文件 config/templates.[语言代码].yaml
复制现有模板结构并翻译内容
更新 src/mailer.js 中的语言支持
更新 .env.template 中的语言选项说明
更新 README.md 和 README.zh.md
更新所有相关文档中的语言列表

文件结构参考

config/
├── templates.zh-CN.yaml  # 简体中文模板
├── templates.zh-HK.yaml  # 繁体中文模板
├── templates.en.yaml      # 英文模板

README.md                # 英文文档
README.zh.md             # 中文文档
.env.template            # 多语言配置模板

自动化提醒

每次修改模板时，检查所有语言版本
每次更新文档时，确保中英文版本同步
每次添加新功能时，考虑所有语言的支持
使用 node bin/cli.js test 测试所有语言模板

常见错误避免

❌ 只更新英文文档，忘记更新中文文档
❌ 只修改简体中文模板，忘记繁体中文和英文模板
❌ 添加新功能时，没有更新所有语言版本
❌ 修改配置说明时，没有同步到所有文档

质量检查

提交代码前，请运行：

# 测试所有功能
node bin/cli.js test

# 检查模板是否能正常加载
node bin/cli.js config

# 验证所有语言的模板文件
ls config/templates.*.yaml
