[Suggestion] OpenAI Codex Agent Plugin with Deepgram STT and TTS (TypeScript)

[deepgram-robot]

What to build

A portable OpenAI Codex Agent Plugin that exposes Deepgram STT and TTS as tools in the Codex plugin marketplace, enabling voice-powered coding workflows directly from the Codex terminal and IDE.

Why this matters

AI coding agents (Codex, Cursor, Claude Code) are becoming primary development interfaces. The Codex plugin marketplace now supports portable Agent Plugins with MCP protocol, making it possible for developers to add voice capabilities — dictate code, listen to TTS readbacks, transcribe meetings for context — without leaving their coding environment. Deepgram currently has no presence in this plugin ecosystem, missing a high-value distribution channel that reaches millions of developers daily.

Suggested scope

• TypeScript implementation following the Codex Agent Plugin protocol
• Tools: transcribe_audio (file or URL → text), transcribe_microphone (live STT from terminal), speak_text (TTS with Aura/Flux voices)
• MCP protocol compatibility for cross-agent portability
• Plugin manifest for marketplace submission
• Uses @deepgram/sdk v5.x
• Minimal dependencies; terminal-native audio I/O

Acceptance criteria

• Runnable with minimal setup (clone, add API key, run)
• README explains the pattern clearly
• Uses current SDK version
• Installs as a Codex Agent Plugin via manifest
• Supports both file-based and live microphone transcription
• TTS output plays directly in the terminal or saves to file
