Security Scan

The skill's instructions (AppleScript via osascript to send Messages) match its stated purpose; no extra credentials or installs are requested — but it is macOS-specific and could send messages autonomously if allowed.

Purpose & Capability

The name/description and SKILL.md are consistent: the skill sends iMessages via AppleScript. However the registry metadata does not declare that this is macOS-only even though it requires osascript/AppleScript and the Messages app; that mismatch should be corrected.

Instruction Scope

SKILL.md contains explicit steps to extract phone number and message and run a single osascript block to send the message. It does not instruct reading unrelated files, accessing extra environment variables, or exfiltrating data.

Install Mechanism

There is no install spec and no code files; this is instruction-only, so nothing is downloaded or written to disk by the skill itself.

Credentials

The skill requests no environment variables or credentials. It properly notes runtime requirements (Messages logged in, Accessibility permissions) which are proportional to sending messages.

Persistence & Privilege

always is false (good). disable-model-invocation is false (normal), which means the agent could autonomously invoke the skill — this increases the risk of the agent sending messages without extra confirmation, though it is not combined with other concerning privileges.

Assessment

This skill is coherent for sending iMessages but only works on macOS with the Messages app signed in. Before installing: confirm you'll run it on macOS; be aware the agent can call the skill autonomously (consider requiring manual confirmation before sending messages); macOS may require Accessibility permission for osascript to control Messages. Also ask the publisher to set the skill's OS restriction to macOS to avoid accidental use on unsupported systems.

iMessage Skill

Send iMessages using macOS Messages app via AppleScript.

Usage

When user asks to send a message to a phone number:

1. Extract the phone number and message from user's request
2. Format phone number with +1 prefix for US numbers (e.g., 8888888888 -> [phone])
3. Use AppleScript to send the message

AppleScript Command

osascript << 'EOF'
tell application "Messages"
    activate
    send "MESSAGE_TEXT" to buddy "+1PHONE_NUMBER"
end tell
EOF

Examples

Send English message:

• User: "send message to 8888888888, say hello"
• Command: send "hello" to buddy "[phone]"

Send Chinese message:

• User: "send to 8888888888 你好"
• Command: send "你好" to buddy "[phone]"

Notes

• The Messages app must be logged into iMessage/FaceTime
• If AppleScript fails, macOS may need Accessibility permissions in System Settings > Privacy & Security > Accessibility
• Works with any text content (English, Chinese, emoji, etc.)
