An on-demand personal daily briefing — weather, headlines, the shape of your day, and one thing worth your attention — in a sharp executive-assistant voice. The general-purpose morning brief; richer work or admin digests compose it as their general layer.
One-time migration of an existing memory-v2 concept corpus into the memory-v3 section-grain "wiki" — topical articles with a stand-alone lead and queryable sections — with loss-proof staging, assistant-reviewed authoring, and a retrieval-eval gate before cutover.
Delegate a big or high-stakes job to a fleet of parallel subagents, orchestrated deterministically; runs unattended and reports back
Manage contacts, communication channels, access control, and invite links
Build and edit small, personal visual tools and artifacts — dashboards, trackers, calculators, data visualizations, charts, simple landing pages, and slide decks the user wants for THEMSELVES. This is the right skill whenever the user asks to "visualize this," "make a chart," or "build an artifact" for their own use, or to edit an app they already built here. Do NOT reach for a ui_show dynamic_page to fake an artifact — build a real persistent app here. NOT for complex, multi-user, or shippable products — those go to a real project folder with a coding agent (see Scope below).

ElevenLabs provides text-to-speech voices for both in-app TTS and phone calls. The config key services.tts.providers.elevenlabs.voiceId controls the voice across all channels. Use the voice_config_update tool to change the voice - it writes to the config file and pushes to the macOS app via SSE in one call.
Pick a voice that matches the your identity and the user's preferences. Offer to show the full list if they want to choose themselves.

To set the chosen voice, use voice_config_update. This writes to the config file (services.tts.providers.elevenlabs.voiceId) for phone calls and pushes to the macOS app via SSE (ttsVoiceId) for in-app TTS in one call:
voice_config_update setting="tts_voice_id" value="<selected-voice-id>"
Verify it worked:
assistant config get services.tts.providers.elevenlabs.voiceId
Tell the user what voice you chose and why, but also offer to show all available voices so they can choose for themselves.
For advanced voice selection (browsing the full library, custom/cloned voices), the user needs an ElevenLabs API key. A free tier is available at https://elevenlabs.io.
To collect the API key securely:
assistant credentials prompt --service elevenlabs --field api_key --label "ElevenLabs API Key"
Users with an ElevenLabs API key can go beyond the curated list above.
assistant credentials inspect --service elevenlabs --field api_key --json
curl -s "https://api.elevenlabs.io/v2/voices?category=premade&page_size=50" \
-H "xi-api-key: $(assistant credentials reveal --service elevenlabs --field api_key)" | python3 -m json.tool
curl -s "https://api.elevenlabs.io/v2/voices?search=warm+female&page_size=10" \
-H "xi-api-key: $(assistant credentials reveal --service elevenlabs --field api_key)" | python3 -m json.tool
If the user has created a custom voice or voice clone in their ElevenLabs account, they can use its voice ID directly. These voices work in both in-app TTS and Twilio ConversationRelay.
Each voice in the API response includes a preview_url with an audio sample the user can listen to before deciding.
After the user picks a voice from the library:
voice_config_update setting="tts_voice_id" value="<selected-voice-id>"
Fine-tune how the selected voice sounds. These parameters apply to all ElevenLabs modes (in-app TTS and phone calls):
# Playback speed (0.7 = slower, 1.0 = normal, 1.2 = faster)
assistant config set services.tts.providers.elevenlabs.speed 1.0
# Stability (0.0 = more expressive/variable, 1.0 = more consistent/monotone)
assistant config set services.tts.providers.elevenlabs.stability 0.5
# Similarity boost (0.0 = more creative, 1.0 = closer to original voice)
assistant config set services.tts.providers.elevenlabs.similarityBoost 0.75
Lower stability makes the voice more expressive but less predictable - good for conversational calls. Higher stability is better for scripted or formal contexts.
By default, the system sends a bare voiceId to Twilio ConversationRelay (no model/tuning suffix). This is the safest default across voice IDs.
To optionally force Twilio's extended voice spec, set a model ID:
assistant config set services.tts.providers.elevenlabs.voiceModelId "flash_v2_5"
When voiceModelId is set, the emitted voice string becomes: voiceId-model-speed_stability_similarity.
To clear and revert to the bare voiceId default:
assistant config set services.tts.providers.elevenlabs.voiceModelId ""
