Caveat verdict

u2-tts

🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

Accesses credentials AND encodes data

Uses UNISOUND_APPKEY and UNISOUND_SECRET to call the UniSound documented TTS WebSocket API for Chinese speech synthesis; the example key in the docs is a placeholder and no exfiltration is present.

Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.
