I built a personal Claude assistant that runs on WhatsApp. It's a single Python process (asyncio) that routes messages to Claude agents running in isolated Docker containers. Each group gets its own filesystem and memory.

  Inspired by NanoClaw (TypeScript, container isolation) and nanobot (Python, simple setup). I wanted both — so
  SlimClaw has per-group isolation like NanoClaw but sets up with pip install slimclaw && slimclaw-setup. No AI
  IDE required.

  Some things it does differently: when someone @mentions the bot in an unregistered group, it notifies your
  admin channel instead of silently ignoring it. You reply "join Family Chat" and the group is live. Skills
  (markdown files) let you add capabilities without touching the core. Model selection (Haiku/Sonnet/Opus) is
  part of onboarding.
