imsg

Use the imsg CLI from OpenClaw agents for iMessage/SMS DMs, groups, replies

imsg is an agent skill from the OpenClaw project, listed on skills.sh. It lets an OpenClaw agent work with iMessage and SMS through the imsg CLI: direct messages, groups, replies, reactions, polls, watching conversations and local Messages history. It prefers OpenClaw's message tool when that can do the job, resolves the right conversation first, and confirms before sending or changing anything visible. Like every skill, it is a SKILL.md file of instructions the agent reads when the task calls for it, so the agent knows which commands to run and what to avoid. It is free and open source in the openclaw/openclaw repository on GitHub.
