Description
Send images from Mac to phone via iMessage
README (SKILL.md)
Send Image via iMessage
Function
Send images from Mac to phone number via iMessage/Messages app.
Usage
Send Image
When user requests to send an image, automatically send via iMessage to the phone.
Manual Commands
# Send image to phone number
python3 ~/.openclaw/workspace/skills/imessage-sender/scripts/send.py send "phone_number" "/path/to/image.png"
First Time Setup
Set the recipient phone number:
python3 ~/.openclaw/workspace/skills/imessage-sender/scripts/send.py config set "your_phone_number"
Image Storage
All images will be automatically copied to:
~/Pictures/openclaw-send/
The script automatically copies images to this directory before sending to avoid path issues.
Usage Guidance
This skill appears to do what it says: it copies images to ~/Pictures/openclaw-send/, stores a small config at ~/.openclaw/...-config.json, and uses macOS osascript to send images via the Messages app. Before installing: (1) confirm you are on macOS and that osascript/Messages are available; (2) review the script if you want to ensure the default recipient isn't set without consent (the agent could call config set); (3) be aware the skill will write images and a config file to your home directory; (4) macOS may prompt for automation/accessibility permissions when osascript controls Messages—confirm those prompts; and (5) if you want stricter safety, run the script manually or inspect and run it in a controlled environment before allowing autonomous agent invocation.
Capability Analysis
Type: OpenClaw Skill
Name: imessage-sender
Version: 1.0.0
The skill provides functionality to send local images via iMessage using AppleScript, but it contains a code injection vulnerability in `scripts/send.py`. The script constructs AppleScript commands by directly embedding user-provided file paths and recipient strings into a command string passed to `osascript` without sanitization, which could allow arbitrary AppleScript execution. While the behavior aligns with the stated purpose, the lack of input validation for shell-equivalent commands poses a significant security risk.
Capability Assessment
Purpose & Capability
The name/description match the included script which uses AppleScript (osascript) to send images via the Messages app. Minor inconsistency: the skill metadata declares no required binaries and no OS restriction, but the implementation depends on macOS (osascript, ~/Pictures path, Messages app). Declaring macOS and osascript as a required runtime would be appropriate.
Instruction Scope
SKILL.md limits runtime behavior to configuring a default recipient, copying images to ~/Pictures/openclaw-send/, and invoking the included send.py. The script only reads/writes a local config (~/.openclaw/...-config.json) and the image copy location, then invokes osascript to send the image. No network calls or unexpected data exfiltration are present.
Install Mechanism
This is an instruction-only skill with a small included script and no install spec; nothing is downloaded or installed by the registry that would increase risk.
Credentials
The script does not request secrets or external credentials. It writes a small JSON config and stores copies of images in ~/Pictures/openclaw-send/. Those file writes are proportional to the stated function.
Persistence & Privilege
The skill is not always-enabled and doesn't modify other skills or system-wide agent settings. It only creates files under the user's home directory for config and image storage.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install imessage-sender - After installation, invoke the skill by name or use
/imessage-sender - Provide required inputs per the skill's parameter spec and get structured output
