使用说明 (SKILL.md)

Go 邮件发送工具

📦 文件说明

mail_sender.exe - 编译后的可执行文件（5.3MB）
main.go - 源代码
go.mod - Go 模块定义

⚙️ 环境变量配置

在 Windows PowerShell 中设置：

$env:SMTP_HOST="smtp.qq.com"
$env:SMTP_PORT="587"
$env:SMTP_USERNAME="[email protected]"
$env:SMTP_PASSWORD="wfpjoocjildcbjeh"
$env:FROM_EMAIL="[email protected]"
$env:FROM_NAME="Agent通知系统"

或在 CMD 中：

set SMTP_HOST=smtp.qq.com
set SMTP_PORT=587
set [email protected]
set SMTP_PASSWORD=wfpjoocjildcbjeh
set [email protected]
set FROM_NAME=Agent通知系统

🚀 使用方法

1. 测试 SMTP 连接

cd mail_sender
$env:SMTP_HOST="smtp.qq.com"
$env:SMTP_PORT="587"
$env:SMTP_USERNAME="[email protected]"
$env:SMTP_PASSWORD="wfpjoocjildcbjeh"
./mail_sender.exe

2. 在代码中调用

import "your-module/mail_sender"

config := mail_sender.NewMailConfig()
email := &mail_sender.Email{
    To:      []string{"[email protected]"},
    Subject: "测试邮件",
    Body:    "\x3Ch1>HTML内容\x3C/h1>",
    Files:   []string{"attachment.pdf"}, // 可选附件
}

err := email.Send(config)

3. 作为命令行工具

# 直接运行（使用默认配置发送测试邮件）
./mail_sender.exe

# 发送自定义邮件（通过修改代码）

安全使用建议

This appears to be a straightforward SMTP email sender, but there are two issues you should address before installing or running it: (1) the package metadata does not list required environment variables even though the code and docs expect SMTP credentials — treat this as an inconsistency and verify what env vars you must provide; (2) the README/SKILL.md include a plaintext SMTP username and password/authorization-code. Assume that credential is compromised: do not reuse it, do not paste your own real password into examples, and rotate/change any account referenced. Recommended actions: review main.go yourself (or rebuild from source rather than running an unknown mail_sender.exe), remove or replace any hard-coded/sample secrets, update the skill metadata to list required env vars, and supply a dedicated mailbox or app-specific password with minimal privileges. If you cannot verify the origin of the embedded credential, avoid running the prebuilt executable and consider contacting the publisher for clarification.

功能分析

Type: OpenClaw Skill Name: gosmtp Version: 1.0.0 The bundle includes a pre-compiled Windows executable (mail_sender.exe) that cannot be verified against the provided Go source code, which is a high-risk practice in agent skills. Both the source code (main.go) and the documentation (SKILL.md/README.md) contain hardcoded SMTP credentials and a hardcoded recipient address ([email protected]), ensuring that any 'test' execution automatically sends a notification to the author. While the visible Go code describes a standard SMTP client, the inclusion of an unverified binary and the 'phone-home' behavior for testing purposes are characteristic of telemetry or potential exfiltration vectors.

⚠ Purpose & Capability

Name/description match an email-sending tool and the Go source implements SMTP sending (STARTTLS, attachments). However the skill metadata declares no required environment variables or primary credential, while both SKILL.md/README and main.go expect SMTP-related environment variables (SMTP_HOST, SMTP_PORT, SMTP_USERNAME, SMTP_PASSWORD, FROM_EMAIL, FROM_NAME). The omission in metadata is an incoherence.

⚠ Instruction Scope

SKILL.md instructs the user to set SMTP environment variables and to run a provided executable or use the Go package; it does not request unrelated files or system info. However the documentation embeds an explicit SMTP_PASSWORD value (plaintext example/credential), which is inappropriate to include and increases risk of credential misuse or leakage.

✓ Install Mechanism

There is no install spec (instruction-only) and the repository includes source (main.go). No remote downloads, installers, or archive extraction are specified, which reduces installation risk. The SKILL.md references a prebuilt mail_sender.exe but no download URL is provided.

⚠ Credentials

Requesting SMTP credentials (username/password) is proportionate for an email tool, but the skill metadata failing to list these env vars is inconsistent. More importantly, the README/SKILL.md contain an explicit SMTP_USERNAME and SMTP_PASSWORD example (looks like an authorization code) — this is a sensitive secret in plaintext and should be treated as leaked. The number of env vars is reasonable, but the presence of a real credential is a notable risk.

✓ Persistence & Privilege

The skill does not request persistent or elevated platform privileges; always:false and default autonomous invocation settings are normal. It does not modify other skills or global config according to provided files.
