feat(media): add image/video/audio project kinds via od media generate
Introduce non-web media surfaces (image, video, audio) as first-class project kinds. The unifying contract is "skill workflow + project metadata tell the agent WHAT to make; one shell command — od media generate — is HOW bytes are produced", so any code-agent CLI with shell access can drive it without bespoke tools. - Frontend: New Project panel gains Image/Video/Audio tabs with model picker, aspect/length/duration controls, and audio kind/voice selection. Examples and Design Systems tabs gain layered sections. FileViewer renders the generated image/video/audio files. - Shared registry: src/media/models.ts is the single source of truth for image/video/audio model IDs, aspects, and defaults — consumed by the picker AND the daemon dispatcher. - Prompts: media-contract.ts is pinned LAST in the system prompt for media surfaces so its hard rules (call od media generate, don't emit binary in <artifact>, allowed model IDs) win over softer earlier wording. - Daemon: new media.js dispatcher + media-models.js JSON view of the registry; cli.js gets the `od media generate` subcommand wired up via server.js / projects.js so the daemon writes files back into the project dir. - Skills: audio-jingle, image-poster, video-shortform seed examples for the three surfaces.

Audio generation skill — jingles, beds, voiceover, and sound effects.

TTS / FishAudio / ElevenLabs V3, and SFX to ElevenLabs SFX or

# 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)`.
|
||||
|
||||
### 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 description (warmth, age, accent, pacing)
|
||||
- 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 "<voice (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.
|
||||
- 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.
