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 known values and use them verbatim. Missing metadata is not
an instruction to ask: infer a safe default when possible, and emit a
clarifying form only when the missing answer would materially change the
requested output or prevent generation.

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:

"$OD_NODE_BIN" "$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.
