使用说明 (SKILL.md)

Mail Sender

This skill allows the agent to send emails using a standard SMTP server (like Gmail, Outlook, etc.).

Setup

The skill uses the following environment variables for configuration:

SMTP_SERVER: (e.g., smtp.gmail.com)
SMTP_PORT: (e.g., 587)
SMTP_USER: Your email address
SMTP_PASS: Your app-specific password
FROM_EMAIL: The sender's email (optional, defaults to SMTP_USER)

Usage

To send an email, use the bundled script:

python3 skills/public/mail-sender/scripts/send.py \
  --to-email "[email protected]" \
  --subject "Hello from OpenClaw" \
  --body "This is a test email sent via the mail-sender skill."

Security Note

For Gmail, use an App Password instead of your primary account password. Never hardcode credentials in the script or conversation history.

安全使用建议

This skill appears to do exactly what it says: run the included Python script to send SMTP email. Before installing, verify the source/publisher (no homepage provided), and provide credentials securely (use env vars or CLI args, not chat). Use an app-specific password or a dedicated sending account rather than your primary mailbox. Ask the publisher to update the registry metadata to declare the required env vars (SMTP_SERVER, SMTP_PORT, SMTP_USER, SMTP_PASS, FROM_EMAIL) for transparency. If you need stronger isolation, run the script in a sandboxed environment or dedicated sending account to limit exposure if credentials are leaked.

功能分析

Type: OpenClaw Skill Name: mail-sender-vutran Version: 1.0.0 The mail-sender skill is a straightforward utility for sending emails via SMTP. The implementation in scripts/send.py uses the standard Python smtplib library with TLS support and correctly handles configuration through environment variables or command-line arguments. No evidence of data exfiltration, hardcoded credentials, or malicious prompt injection was found.

能力评估

ℹ Purpose & Capability

The name/description, SKILL.md, and the included Python script all align: the skill sends email via SMTP and requires SMTP server, port, user, and password. However, the registry metadata lists no required environment variables even though the SKILL.md and script clearly rely on SMTP-related env vars — a transparency mismatch.

✓ Instruction Scope

SKILL.md instructs only how to configure SMTP creds and run the bundled script. The script only reads SMTP-related environment variables/arguments and connects to the specified SMTP server; it does not access other files, system config, or external endpoints beyond the provided SMTP host.

✓ Install Mechanism

There is no install spec (instruction-only with a bundled script). No third-party downloads or package installs are requested, which keeps installation risk low.

ℹ Credentials

The skill legitimately requires sensitive credentials (SMTP_USER and SMTP_PASS). That is proportionate for sending email, but the registry metadata failing to declare these required env vars is concerning for transparency. Users should provide these secrets securely (env vars or runtime args) and avoid embedding them in chat history.

✓ Persistence & Privilege

The skill is not marked 'always', does not modify other skills or system configuration, and does not request persistent/system-wide privileges. It behaves as an on-demand tool.
