# Add Ai Message To History

`POST /ai-voice/add-ai-message`

Add an AI message to the conversation history (used for pre-generated welcome messages).

Signed in, and only the caller's own session (2026-09-18 route-auth
review). It writes attacker-chosen text into a ChaCha conversation
history, which is then fed back to the model as context on the next turn,
so an open version of this is a prompt-injection hole as well as a
tampering one.
