Add voice ai skill

[OmerBassan]

Description

Voice AI Architect is a specialized engineering skill designed to be triggered when developers need to architect, design, or implement production-ready voice conversation flows using LangGraph. Its capabilities include iterative discovery of business logic, generation of Mermaid.js state machine diagrams, voice-optimized prompt engineering, and clean Python code implementation for robust, interruptible voice agents.

Heads-up from skills-il maintainers: a new CI step landed in this repo on 2026-05-17 that requires every touched skill folder to include evidence.json, a structured list of every factual claim in the skill paired with the official source URL it came from. See /he/guides/how-we-validate for the full rationale.

This PR will currently fail the Skill Validation check. Two paths forward:

1. You add evidence.json to your skill folder. Schema: a JSON array of { "claim": "...", "source_url": "https://..." } objects, one entry per concrete fact (form number, fee amount, deadline, statute reference, percentage, etc.). Every claim must be sourced to an official URL.
2. We backfill it for you when we next triage submissions. Reply on this PR if you'd prefer that route.

Either way, we won't silently merge skills missing the evidence file. It would undermine the public promise the guide makes. Sorry for the disruption mid-PR.
