supercall
This skill enables AI-powered phone calls using OpenAI Realtime and Twilio, registering a `supercall` tool, webhook server, and media streaming endpoints. It runs local CLIs (`ngrok`, `tailscale`), opens network connections to `wss://api.openai.com/v1/realtime` and `https://api.twilio.com/2010-04-01/Accounts/${this.accountSid}`, and reads credentials from env vars like `OPENAI_API_KEY` and `TWILIO_AUTH_TOKEN`.
