SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyyaml, and includes scripts (resource) components.

What problem does it solve?

This Skill gives Hermes practical phone capabilities without changing the core tool set, so it can own a reusable number, send texts, place calls, and check messages later from the same telephony identity.

Core Features & Use Cases

Twilio Number Management: Search for, buy, persist, and reuse an owned Twilio number across sessions.
Messaging and Voice: Send SMS or MMS, make direct calls with spoken messages or audio playback, and navigate phone trees with DTMF digits.
AI Calling Workflows: Place outbound AI-assisted calls through Bland.ai or Vapi, with support for number import, status checks, and post-call analysis.
Use Case: A user can provision a business line, receive deployment alerts by text, and ask Hermes to call a vendor or appointment desk on their behalf.

Quick Start

Ask Hermes to set up the telephony skill, configure Twilio, and then use the owned number to send a test text or place a call after you confirm the destination.
