CallMe
Minimal plugin that lets Claude Code call you on the phone.
Start a task, walk away. Your phone/watch rings when Claude is done, stuck, or needs a decision.
- Minimal plugin - Does one thing: call you on the phone. No crazy setups.
- Multi-turn conversations - Talk through decisions naturally.
- Works anywhere - Smartphone, smartwatch, or even landline!
- Tool-use composable - Claude can e.g. do a web search while on a call with you.
