…or restricted tools When the LLM attempts to call a voice-restricted tool (e.g. initiateAgenticLoop, runSRAnalysis) during a Daily.co voice session, intercept it via the LLM's on_function_calls_started event, speak a short TTS redirect message, and emit a custom 'voice-to-chat-redirect' RTVI server message to the Lighthouse frontend.
WalkthroughA new voice-mode restriction system has been implemented for Breeze Buddy. A utility module defines restricted tools and a redirect message, while the agent now intercepts restricted tool calls during voice sessions and redirects users to chat mode with audio feedback. Changes

Pull request overview
Adds a Breeze Buddy voice-mode safeguard that detects attempts to invoke long-running “chat-only” tools and redirects the user to chat by speaking a short TTS message and emitting an RTVI voice-to-chat-redirect server event (Daily non-stream mode only).
Changes:
- Introduces
VOICE_RESTRICTED_TOOLSandVOICE_REDIRECT_TTS_MESSAGEconstants for centralized tool restriction configuration. - Stores the LLM service reference on the agent instance and registers an
on_function_calls_startedhandler to trigger the voice-to-chat redirect behavior.

The on_function_calls_started handler only emits a redirect message/event but does not prevent the restricted tool from executing. If these tools are long-running (as the docstring suggests), they can still consume LLM context/compute even after the redirect. To actually enforce the restriction in voice mode, block execution (e.g., don’t register these tools for voice sessions, or short-circuit their handlers to immediately return a safe result and skip the real work, and/or cancel/terminate the current pipeline after emitting the redirect).

After a restricted tool is detected, the handler emits a redirect but doesn’t guard against subsequent restricted tool calls later in the same session. This can lead to repeated TTS messages and duplicate voice-to-chat-redirect events if the LLM retries or calls multiple restricted tools across turns. Consider adding an idempotency flag (emit once per conversation) and/or ending the voice session after emitting the redirect.

Fix the Black formatting failure.

The on_function_calls_started handler does not prevent execution of restricted tools; it only notifies.
The handler at lines 657–690 is notification-only: it logs the interception, queues a TTS redirect message, and emits an RTVI event, but does not modify the function_calls list, return a cancellation signal, or prevent execution. If these tools are registered in the template's global_functions config (and GlobalFunctionRegistry.build() applies no filtering), they will execute after the handler fires, potentially exhausting LLM context during voice conversations.
Either exclude restricted tools from registration in voice mode, or register voice-mode stubs for the five tools in VOICE_RESTRICTED_TOOLS that only emit the redirect response and return early.
