+description: Handle voice assistant requests received via the wake-word pipeline. Use when a request arrives tagged as a voice command or comes through the wake-word webhook (/wake endpoint). Respond concisely — responses will be spoken aloud via TTS (Kokoro). Avoid markdown, lists, or formatting that doesn't work in speech. Keep replies to 1–2 sentences unless detail is requested.

+
+# Voice Assistant Skill
+
+## Context
+
+This assistant runs on a Mac Mini (LINDBLUM, 10.0.0.200). Requests may arrive:
+- Via the `/wake` HTTP webhook (wake word detected by openWakeWord)
+- Via Home Assistant Wyoming voice pipeline
+- Via direct text input
+
+## Response style for voice
+
+- Speak naturally, as if in conversation
+- Keep it short — 1–2 sentences by default
+- No bullet points, headers, or markdown
+- Say numbers as words when appropriate ("twenty-two degrees" not "22°C")
+- Use the character's personality (defined in system prompt)
+
+## TTS pipeline
+
+Responses are rendered by Kokoro ONNX (port 10301, voice: af_heart) and played back through the requesting room's speaker.
+
+## Smart home integration
+
+For device control requests, use the `home-assistant` skill. HA is at 10.0.0.199:8123.
+
+## Wake word webhook
+
+POST to `http://localhost:8080/wake` triggers this context:
+```json
+{"wake_word": "hey_jarvis", "score": 0.87}
+```
+After wake, wait for the transcribed utterance from the STT pipeline (Whisper large-v3, port 10300).
