+# Audio Jingle Skill
+
+Three sub-modes. The active project's `audioKind` decides which one
+runs:
+
+| `audioKind` | Models we route to | Plan focus |
+|---|---|---|
+| `music` | Suno V5 (default), Udio, Lyria 2 | genre + tempo + instrumentation |
+| `speech` | MiniMax TTS (default), Fish, ElevenLabs V3 | script + voice + pacing |
+| `sfx` | ElevenLabs SFX (default), AudioCraft | texture + impact + duration |

+
+## Workflow
+
+### Step 0 — Read the project metadata
+
+`audioKind`, `audioModel`, `audioDuration` (seconds), and (for speech)
+`voice`. Branch by `audioKind` and use the values verbatim — no
+clarifying form unless something is marked `(unknown — ask)`.
+
+Important: `voice` is provider-specific. For `minimax-tts`, `--voice`
+must be a valid MiniMax `voice_id` (for example `male-qn-qingse`), not
+a natural-language description. If you only have a prose voice brief
+("warm female narrator", "neutral Mandarin"), keep that in your plan
+but omit `--voice` so the daemon's default voice id applies, or ask the
+user to choose a specific id.
+
+### Step 1 — Plan
+
+**Music**
+- Genre + reference artists (1-2)
+- Tempo (BPM) + key
+- Instrumentation (3-5 instruments max)
+- Vocals: yes / no / hummed / choir
+- Mood arc (intro → chorus → outro)
+
+**Speech**
+- Script (final, not draft — TTS runs verbatim)
+- Voice target + pacing
+  For MiniMax this means a real `voice_id`, not prose in `--voice`
+- Pronunciation hints for proper nouns / acronyms
+
+**SFX**
+- Texture (impact / whoosh / ambience / foley)
+- Duration + envelope (sharp attack vs. gentle swell)
+- Layering note (single hit vs. stacked)
+
+State the plan in 2-3 sentences before dispatching.
+
+### Step 2 — Compose the prompt
+
+Use the format the upstream model prefers. Bind `audioDuration` to the
+API parameter directly; never put "make it 30 seconds" in prose.
+
+### Step 3 — Dispatch via the media contract
+
+Use the unified dispatcher — do **not** call provider APIs by hand:
+
+```bash
+node "$OD_BIN" media generate \
+  --project "$OD_PROJECT_ID" \
+  --surface audio \
+  --audio-kind "<music|speech|sfx>" \
+  --model "<audioModel from metadata>" \
+  --duration <audioDuration seconds> \
+  [--voice "<provider voice id (speech only)>"] \
+  --output "<short-slug>-<duration>s.mp3" \
+  --prompt "<assembled prompt from Step 2 — for speech, the literal script>"
+```
+
+The command prints one line of JSON: `{"file": {"name": "...", ...}}`.
+The bytes land in the project; the FileViewer renders the audio
+transport controls automatically.
+
+### Step 4 — Hand off
+
+Reply with: plan summary, the filename returned by the dispatcher, and
+one sentence on what to try if the user wants a variation (e.g. "swap
+tempo from 92 to 108 BPM" rather than "make it different").
+
+## Hard rules
+
+- TTS runs your script **literally**. Proof it before dispatching —
+  even one stray comma changes the cadence.
+- MiniMax TTS rejects free-form voice prose in `--voice`. Use a real
+  MiniMax `voice_id` (for example `male-qn-qingse`) or omit the flag
+  and let the daemon's default voice apply.
+- Music: under 30s = single section; 30–90s = intro + body; 90s+ =
+  full arc. Don't try to fit a 3-act song into 15 seconds.
+- SFX: prefer one well-described layer over a paragraph of "make it
+  cool" — generators reward specific texture words.
+- Save the file every turn. The audio viewer shows transport controls
+  the moment the file lands.
