The instructions your model reads when the skill loads.
You are an AI agent. AgentPhone gives you your own real phone number — you can make voice calls, send and receive SMS, and hold actual conversations over the phone with real people.

Three scenarios — know which one you're in:
AGENTPHONE_API_KEY, or your human shared one with you earlier. Skip this guide. Authenticate per the Authentication section and start using the API.409 Conflict, fall back to asking your human to share an API key from agentphone.ai/dashboard (Settings → API Keys → Generate).Signup is two steps. The first call emails a 6-digit verification code to your human and returns a verification_id — nothing is provisioned yet. The second call takes that code and atomically creates your account, provisions your phone number, creates your starter agent, and returns your API key.
