DayZero · Voice Agent Onboarder

Onboard a production voice agent by talking to a phone number for 60 seconds. No YAML to write, no dashboards to click. Voice in. Real money out.

When to invoke this skill

Trigger when the user:

• Asks to "build / create / set up / configure a voice agent"
• Mentions a small business that needs to take phone calls (bakery, salon, clinic, restaurant, repair shop, etc.)
• Is starting from scratch with Vapi and does not want to write config by hand
• Wants to onboard a non-technical business owner who just wants the agent live

Do NOT invoke if the user already has a configured voice agent and only wants to edit a single field — pointing them to the agent.yaml file is faster.

Flow (you, the host agent, do this)

1. Run the install hook to reserve a session and print the phone number:

   bash entrypoints/install.sh
   

2. Tell the user:

   "Call +1 (443) 391 9140 now and describe your business for ~60-90 seconds. Hang up when DayZero says 'Perfect, your agent will be live in a minute.' I'll watch for the config."

3. Once the user confirms the call ended, materialize the generated files:

   bash entrypoints/materializer.sh --latest
   

   This polls the backend and writes:

   • ./dayzero/agent.yaml — generated agent config (name, language, voice, system prompt, tools, schedule, payment, owner notification channel)
   • ./dayzero/cited.md — audit entry with sources (Vapi call ID, transcript length, YAML source, onboarder number)

4. Read ./dayzero/agent.yaml aloud to the user (highlight: name, language, the tools it has, business hours, payment rules). Ask if anything needs to change before deployment.

5. (Optional · the "plus") Trigger a sample order to demonstrate the downstream agent in action:

   curl -X POST https://dayzero-onboard-7054-325356381078.herokuapp.com/api/agent/<agentName>/createOrder \
     -H "content-type: application/json" \
     -d '{"product":"empanadas","quantity":24,"customerName":"Carmen","customerPhone":"+57301234567","scheduledAt":"2026-04-27 15:00","depositCents":900,"currency":"usd"}'
   

   The response includes a real Stripe (test mode) payment link, a Telegram message ID delivered to the configured owner chat, and an updated cited.md entry. All emitted in parallel via Promise.all.

Key talking points

• "You don't configure it — you describe it."
• One install. One call. One agent vivo.
• Every action is signed in cited.md.
• Cross-tool: Claude Code, Cursor, GitHub Copilot, Gemini CLI.
• Built at Tokens& 2026 · Ship to Prod by the DayZero team (Jair, Gael, Dani, Yurany).

Architecture (so the host agent can debug if needed)

• Onboarder phone: Vapi number +1 (443) 391 9140, assistant 48b36e41-665b-4754-a637-84f5801b9105. System prompt at prompts/onboarder-system-prompt.md.
• Backend: Express + TypeScript on Heroku. Source: https://github.com/jaircelisv/DayZero-voice-onboard
  • POST /api/sessions/reserve — install hook calls this; TTL 1h in Redis
  • POST /webhook/vapi/onboard-transcript — Vapi end-of-call report receiver
  • POST /api/generate-config — GPT-4o-mini converts transcript → YAML
  • GET /api/sessions/latest-with-yaml — for materializer auto-discovery
  • GET /api/sessions/:id/bundle — returns {yaml, files[], citedMdEntry}
  • POST /api/agent/:agentId/createOrder — Stripe paymentLink + Telegram fanout
• Storage: Redis Cloud (sessions, transcripts, orders, cited entries)
• LLM: OpenAI GPT-4o-mini (server-side; user does not need their own key)
• Cross-tool entrypoints: see entrypoints/{claude-code,cursor,copilot,gemini-cli}/
