Synthesize speech via Google's gemini-2.5-flash-preview-tts (or -pro-tts / -lite-preview-tts per env override). Reads GEMINI_API_KEY from .env.
This is offline synthesis — distinct from voice-agent's bidirectional Gemini Live audio. Same model family, different surface (POST text → get audio bytes back, no streaming).
Usage: /gemini-tts [text]
ARGUMENTS: $ARGUMENTS
Aoede (default — alto, neutral), Charon (baritone, news-anchor), Kore (mid, expressive), Puck (high, conversational). Per Lucy's 2026-05-09 testing: Aoede is the closest match to OpenAI's sage.
Inline bracket tags like [whispers], [excitedly], [slowly] are interpreted as stylistic direction, not spoken literally. Empirically verified against gemini-2.5-flash-preview-tts (per PR #646 comment): [whispers] hello → 1.05s audio; hello alone → 1.01s. If the tag were spoken literally as 8 words, the clip would be ~5× longer.
bash "$SKILL_DIR/scripts/synthesize.sh" -- "[whispers] Pull request 691 has landed."
Default: gemini-2.5-flash-preview-tts (free tier, 1500 req/day, $0 within quota).
Override via GEMINI_TTS_MODEL env var:

GEMINI_TTS_MODEL=gemini-2.5-pro-tts bash "$SKILL_DIR/scripts/synthesize.sh" -- "High-fidelity narration."
Default output path: results/gemini-tts-{epoch}.mp3.
Free tier: $0 within 1500 req/day quota. For our cadence (a few demos a day), stays free indefinitely. Paid (Flash): $0.50 / 1M input tokens + $10.00 / 1M output tokens.
Compared to OpenAI TTS (gpt-4o-mini-tts) at ~$0.02 per 60s: Gemini Flash is free-equivalent for typical demo workloads.

Make conversational phone calls and join Zoom meetings via Twilio + Gemini. Multi-turn AI conversations on the phone on behalf of the user.
File a bug report, feature request, or feedback about Sutando to the team from any surface (chat, Discord, Telegram, or a voice-delegated task). Reuses the cloud /api/feedback API and auto-attaches diagnostic context. Use when the user says "report a bug", "something's broken, file it", "I have a feature request", etc.
Track Claude Code quota usage via Anthropic API rate limit headers. Shows 5h and 7d utilization, reset times, and quota status. Works with both subscription and API key auth.
Zoom meeting control for Sutando's voice and phone agents — contributes the summon (join + screen share), dismiss (leave meeting), and join_zoom (join with computer audio, no share) inline tools.
Framework + minimal example for Sutando desktop overlay applications — always-on-top, frameless Electron windows that float over the desktop, controllable from the Sutando web UI's /overlays manager. Ships one example overlay (System Resources). Add new overlays by registering them in app/main.js.
Local Agent Registry — a standalone, dependency-free service that tracks running Claude Code (and other) agent instances. Agents self-register on startup and heartbeat while alive; the Electron overlay and Sutando dashboard read the live list. Use when you need to know which coding agents are running, where, and since when.
