README (SKILL.md)
Email Send Skill
Send a quick email via SMTP without opening the full himalaya client. Requires SMTP_HOST, SMTP_PORT, SMTP_USER, SMTP_PASS env vars.
Sending Email
Send a basic email:
echo "Meeting at 3pm tomorrow." | msmtp [email protected]
Send with subject and headers:
printf "To: [email protected]\
Subject: Quick update\
\
Hey, the deploy is done." | msmtp [email protected]
Options
--cc-- carbon copy recipients--bcc-- blind carbon copy recipients--attach \x3Cfile>-- attach a file
Install
sudo dnf install msmtp
Usage Guidance
Install only if you want an agent to send mail through your SMTP account. Use a dedicated app password or scoped SMTP credential when possible, keep SMTP_PASS out of prompts and files, and verify every recipient, message, and attachment before sending.
Capability Analysis
Type: OpenClaw Skill
Name: email-send
Version: 1.0.0
The skill is classified as suspicious due to its explicit instruction in SKILL.md for the AI agent to access sensitive environment variables (`SMTP_HOST`, `SMTP_PORT`, `SMTP_USER`, `SMTP_PASS`) which contain credentials. Additionally, the `--attach <file>` option, while legitimate for email, grants the agent the capability to read arbitrary files from the filesystem. While these capabilities are plausibly needed for the stated purpose of sending email, they represent high-risk behaviors without clear malicious intent within the provided skill definition, aligning with the 'suspicious' threshold.
Capability Assessment
Purpose & Capability
The documented capability is sending email through msmtp, including cc, bcc, and attachments; this is high-impact outbound communication but directly matches the stated purpose.
Instruction Scope
The runtime instructions are simple user-directed msmtp examples with no hidden automation, though they do not explicitly require confirmation of recipients, message body, or attachment paths before sending.
Install Mechanism
The install metadata only requests the standard msmtp package through dnf and declares the msmtp binary requirement; no bundled scripts, install hooks, or unusual package behavior were found.
Credentials
SMTP_HOST, SMTP_PORT, SMTP_USER, and SMTP_PASS are proportionate for SMTP sending, but users should treat them as account secrets and avoid exposing them in chat, logs, shell history, or committed files.
Persistence & Privilege
The artifact contains only markdown instructions and metadata; no persistence, background process, privilege escalation beyond user-directed package installation, credential storage, or unrelated data collection is present.
How to Use
- Make sure OpenClaw is installed (local or Docker)
