Build Your Own Voice-First AI Agent — From Empty Repo to a Talking, Tool-Using, Always-On Assistant in One Session

Paste this into Claude Code, Cursor, or Codex and it'll interview you, help you name your agent, then walk your codebase through building a voice-first assistant tier by tier: a text conversation loop you can debug before you ever add audio, a tool registry that lets the agent actually do things, real speech-in and speech-out (Deepgram for transcription, ElevenLabs for voice) so you talk to it instead of typing, memory that survives a restart, an always-on background loop so the agent can reach out to you first, and the safety rails that keep a proactive assistant from doing something you didn't ask for. Interview first, then build tier by tier. Each tier runs on its own and is verified before the next begins.
