What it does

This skill teaches an AI agent how to work with AgentPhone, a paid telephony service that gives AI agents phone numbers, voice calls and text messaging through an API. Once installed, the agent knows the API base URL, the recommended setup order (create agent, buy number, set webhook, make calls), and safety rules such as using E.164 phone number formatting, confirming before releasing numbers, and never sending the API key anywhere except the AgentPhone domain. The skill is a guide and reference; it does not itself make calls or buy numbers, but an agent following it may do so if the user asks and an AgentPhone key is available.

Great for

  • Developers building AI voice or SMS agents who want a telephony backend
  • Teams testing automated phone workflows with owned test numbers before any live use
  • Builders who need guidance on webhooks, voices and usage checks for AgentPhone

Skip it if

  • Anyone wanting to make unsolicited or marketing calls or texts, since the skill itself warns that outbound automation needs explicit recipients, disclosed AI role, opt-outs and legal compliance
  • Non-technical users without an AgentPhone account and API key, since the skill cannot create one
  • Situations needing guaranteed current API details, since the bundled guide is version-dependent and the skill says to verify against current docs

Try asking

  • “Help me set up an AI phone agent that answers inbound calls for my test number”
  • “List my current AgentPhone numbers and usage before I make any changes”
  • “Write the webhook configuration for receiving SMS on my AgentPhone number”
  • “Show me available voices and create a voice agent with a friendly tone”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Start with owned test numbers and set a clear spend limit and call duration bound before asking the agent to buy numbers or place calls
  • Explicitly state recipients, purpose and the AI disclosure you want, since the skill requires these before activation
  • Check the current AgentPhone docs for endpoint and voice ID details, because the bundled guide may be out of date
