Create the agent and save its token: build an agent.
Set its profile picture on its Contact Card: profile picture.
Run one process that reads its events over the WebSocket and texts back: texting agent.
When it runs, text its owner hello, once: text the owner.
Answer calls in that same process and bridge the audio to any voice provider: answer calls.
Send its own video on every call, from any frame source: the agent's camera.
When calls are set up, call its owner so they can try it: call a person.

Finish each step by running it against Relay, not only by compiling.

Route

Contract, routes, fields, events: the locked reference and contracts/relay-v1-openapi.yaml. Report hash or source drift.
Messages, buttons, list pickers, rich cards, carousels, forms, payments, places, threads, voice memos: messaging.
Chats, contacts, sharing a card, person fields, chat activity: chats and contacts.
Calls, call events, video, Rive, voice frameworks: calls.
GET /v1/me, who can message the agent, Log in with Relay, hosted MCP: agent settings.
Public agent directory: directory.
Webhooks, WebSocket, ACK, replay, sync: agent events.
Tokens, environments, retries, errors, TypeScript and Python SDKs: SDK and auth.
CLI commands and profiles, skill installation: CLI and skills.
Asking a person for a rating: ratings.

Rules

Never invent a route, field, event, package, or product rule. Mark behavior the contract does not prove as unknown.
Prefer @relaymessenger/sdk for TypeScript and relaymessenger for Python.
Keep tokens and API keys in .env or a secret store; never print them, commit them, or put them in command arguments.
Use one API origin and token from the same environment for every request.
Every person-visible string comes from the model; never send canned text.
