tests/test_example.py::test_deepgram_stt PASSED                          [ 50%]

======================== 2 passed, 2 warnings in 2.76s =========================

Both tests pass with real credentials. Deepgram STT returned a valid transcript (length > 10). Agent module imports cleanly.

Integration genuineness

Pass — src/agent.py imports livekit.agents, livekit.plugins.silero, and wires Deepgram via inference.STT("deepgram/nova-3"). .env.example lists five real platform credentials (LiveKit, Deepgram, OpenAI). Test exits with code 2 when credentials are missing.

Code quality

• ✅ Official Deepgram SDK pinned to deepgram-sdk==6.1.1 (required version)
• ✅ tag="deepgram-examples" present on transcribe_url() call in test
• ✅ No hardcoded credentials — all sourced from environment
• ✅ Credential check runs before SDK imports (lines 6–15 of test)
• ✅ Transcript assertion uses len(transcript) > 10 (length-based, not word-list)
• ✅ No raw HTTP to Deepgram — uses official SDK

Documentation

• ✅ README covers what-you'll-build, all env vars with where-to-get links, install/run instructions
• ✅ .env.example present and complete (5 variables)

✓ All checks pass. Ready for merge.
