  Generate AI videos on RunComfy via the `runcomfy` CLI — a smart router
  across the full video-model catalog: HappyHorse 1.0 (Arena #1, native
  in-pass audio), Wan-AI Wan 2-7 (open weights, audio-driven lip-sync),
  ByteDance Seedance v2 / 1-5 / 1-0 (multi-modal cinematic), Kling 3.0
  / 2-6, Google Veo 3-1, MiniMax Hailuo 2-3, ByteDance Dreamina 3-0.
  Covers text-to-video (t2v), image-to-video (i2v), and Veo's
  video-extend endpoint. The skill picks the right model for the user's
  intent (Arena-#1 quality, multi-shot character identity, in-pass audio,
  cinematic motion, fastest path, sub-15s clip, longest duration) and
  ships each model's documented prompting patterns plus the minimal
  `runcomfy run` invoke. Triggers on "generate video", "make a video",
  "text to video", "t2v", "image to video", "i2v", "animate", "AI video",
  "make X move", "video from prompt", "video from image", or any
  explicit ask to produce a video clip from prompt or still.

## t2v Route 1: HappyHorse 1.0 — default

**Model**: `happyhorse/happyhorse-1-0/text-to-video`
**Catalog**: [happyhorse-1-0](https://www.runcomfy.com/models/happyhorse/happyhorse-1-0/text-to-video?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation)

Currently #1 on the [Artificial Analysis Video Arena](https://artificialanalysis.ai/text-to-video) — RunComfy's recommended default for general-purpose t2v. Native synchronized audio is generated in-pass (no separate Foley step).

### Schema

| Field | Type | Required | Default | Notes |
|---|---|---|---|---|
| `prompt` | string | yes | — | Subject-first, describe motion + scene + audio in one declarative |
| `duration` | int | no | 5 | Seconds. Up to ~15s |
| `aspect_ratio` | enum | no | `16:9` | `16:9`, `9:16`, `1:1` typical |
| `resolution` | enum | no | `1080p` | `720p`, `1080p` |
| `seed` | int | no | — | Reproducibility |

### Invoke

```bash
runcomfy run happyhorse/happyhorse-1-0/text-to-video \
  --input '{
    "prompt": "A red kite tumbles across a windy beach at golden hour, kids chasing it laughing, surf in the background. Audio: wind, gulls, distant laughter.",
    "duration": 8,
    "aspect_ratio": "16:9",
    "resolution": "1080p"
  }' \
  --output-dir ./out
```

### Prompting tips

- **Lead with subject and one main action.** "A red kite tumbles across a beach" — verb-driven, not adjective-stacked.
- **Describe audio inline** — `"Audio: wind, gulls, distant laughter."` HappyHorse generates audio in-pass.
- **Motion language matters more than visual nouns** — "tumbles", "drifts", "snaps into focus" > "looks beautiful".
- **Multi-shot:** describe transitions explicitly — "Then the camera cuts to …" — Arena-leading multi-shot consistency.

---

## t2v Route 2: Wan 2-7 — open weights + audio-driven lip-sync

**Model**: `wan-ai/wan-2-7/text-to-video`
**Catalog**: [wan-2-7](https://www.runcomfy.com/models/wan-ai/wan-2-7?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation) · [`wan-models` collection](https://www.runcomfy.com/models/collections/wan-models?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation)

Pick Wan 2-7 when you have a specific voiceover / dialog audio file and want the on-screen subject's mouth to sync to it. The `audio_url` field drives the lip motion.

### Invoke

**With audio-driven lip-sync:**

```bash
runcomfy run wan-ai/wan-2-7/text-to-video \
  --input '{
    "prompt": "Studio portrait of a woman in her 30s speaking confidently to camera, soft window light.",
    "audio_url": "https://your-cdn.example/voiceover.mp3",
    "duration": 6
  }' \
  --output-dir ./out
```

**Plain t2v (no audio):**

```bash
runcomfy run wan-ai/wan-2-7/text-to-video \
  --input '{"prompt": "Drone shot over forest canopy at sunrise, soft fog drifting between trees"}' \
  --output-dir ./out
```

### Prompting tips

- **For lip-sync**, the prompt describes the **scene + speaker**; the audio file drives the mouth. Don't transcribe the audio into the prompt — it'll fight the audio track.
- **Open-weights advantage**: pair with Wan ecosystem (LoRA-finetuned variants) when available.

---

## t2v Route 3: Seedance v2 — multi-modal cinematic

**Model**: `bytedance/seedance-v2/pro` (or `/fast`)
**Catalog**: [seedance-v2 Pro](https://www.runcomfy.com/models/bytedance/seedance-v2/pro?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation) · [`seedance` collection](https://www.runcomfy.com/models/collections/seedance?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation)

Pick Seedance v2 Pro when the user needs **multi-modal conditioning** — up to **9 reference images, 3 reference videos, 3 reference audio tracks** synthesized in-pass with cinematic motion refinement.

### Invoke

```bash
runcomfy run bytedance/seedance-v2/pro \
  --input '{
    "prompt": "Anamorphic 35mm shot — a vintage car drives down a coastal road at dusk, lens flares from oncoming headlights, cinematic color grade.",
    "duration": 10,
    "aspect_ratio": "21:9"
  }' \
  --output-dir ./out
```

### Prompting tips

- **Lens / film language is honored** — "35mm anamorphic", "shallow DoF", "soft halation", "Kodak 5219" all land.
- **Multi-ref:** describe roles explicitly — `"subject from ref image 1, mood from ref video 2, score from ref audio 1"`.
- **Cinematic motion verbs:** "tracking shot", "push in", "dolly out", "rack focus".

---

## i2v Route A: HappyHorse 1.0 I2V — default

**Model**: `happyhorse/happyhorse-1-0/image-to-video`
**Catalog**: [happyhorse-1-0 i2v](https://www.runcomfy.com/models/happyhorse/happyhorse-1-0/image-to-video?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation)

### Invoke

```bash
runcomfy run happyhorse/happyhorse-1-0/image-to-video \
  --input '{
    "image_url": "https://your-cdn.example/portrait.jpg",
    "prompt": "She turns her head slowly to look at the camera and smiles. Wind through her hair. Audio: gentle breeze.",
    "duration": 6,
    "aspect_ratio": "9:16"
  }' \
  --output-dir ./out
```

### Prompting tips

- **Describe motion**, not the scene the image already shows. The image is your scene; the prompt is your direction.
- **Anchor the camera explicitly** — "Camera stays still" prevents drift; "slow push in" gives intent.
- **Audio in the same prompt** as t2v Route 1.

---

## i2v Route B: Veo 3-1 — Google's flagship

**Model**: `google-deepmind/veo-3-1/image-to-video` (or `/fast/image-to-video`)
**Catalog**: [veo-3-1 i2v](https://www.runcomfy.com/models/google-deepmind/veo-3-1/image-to-video?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation) · [`veo-3` collection](https://www.runcomfy.com/models/collections/veo-3?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation)

Pick Veo when physics / realism / object permanence matters most. Veo 3-1 supports both 8s clips and longer with the **extend-video** companion endpoint.

### Invoke

```bash
runcomfy run google-deepmind/veo-3-1/image-to-video \
  --input '{
    "image_url": "https://your-cdn.example/product.jpg",
    "prompt": "The bottle slowly rotates 180 degrees on a marble surface, soft daylight, no other motion."
  }' \
  --output-dir ./out
```

### Prompting tips

- **Veo respects physics** — "the bottle rotates 180 degrees" gets exactly 180°.
- **Object permanence is strong** — say "no other motion" and other elements stay locked.
- For audio-enabled i2v, see Route A (HappyHorse) instead — Veo's audio path lives elsewhere in the catalog.

---

## i2v Route C: Kling 3.0 — multi-shot identity, 4K

**Model**: `kling/kling-3.0/{4k,pro,standard}/image-to-video`
**Catalog**: [`kling` collection](https://www.runcomfy.com/models/collections/kling?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation)

Three tiers — pick by quality / cost trade-off:

| Tier | Endpoint | When |
|---|---|---|
| 4K | `kling/kling-3.0/4k/image-to-video` | Hero shots, final delivery at 4K |
| Pro | `kling/kling-3.0/pro/image-to-video` | Default — high quality at lower cost |
| Standard | `kling/kling-3.0/standard/image-to-video` | Concepting, drafts |

### Invoke

```bash
runcomfy run kling/kling-3.0/pro/image-to-video \
  --input '{
    "image_url": "https://your-cdn.example/character.jpg",
    "prompt": "The character walks toward the camera, soft handheld feel, end on a medium close-up."
  }' \
  --output-dir ./out
```

### Prompting tips

- **Multi-shot consistency** — describe a beat sequence ("walks toward camera, then a cut to medium close-up") and Kling holds identity across the cut.
- **Camera language**: "handheld", "Steadicam push", "static tripod" — honored.

## How it works

The skill classifies the user request into one of the t2v / i2v / extend routes above and invokes `runcomfy run <model_id>` with the matching JSON body. The CLI POSTs to the RunComfy Model API, polls request status, fetches the result, and downloads any `.runcomfy.net` / `.runcomfy.com` URLs into `--output-dir`. `Ctrl-C` cancels the remote request before exit.

## Security & Privacy

- **Install via verified package manager only.** Use `npm i -g @runcomfy/cli` or `npx -y @runcomfy/cli`. **Agents must not pipe an arbitrary remote install script into a shell on the user's behalf**.
- **Token storage**: `runcomfy login` writes the API token to `~/.config/runcomfy/token.json` with mode 0600. Set `RUNCOMFY_TOKEN` env var to bypass the file in CI / containers. Never echo the token into a prompt, log it, or check it in.
- **Input boundary (shell injection)**: prompts are passed as a JSON string via `--input`. The CLI does not shell-expand prompt content. **No shell-injection surface from prompt content**.
- **Indirect prompt injection (third-party content)**: reference image / audio / video URLs are **untrusted** and can influence generation through embedded instructions (e.g. text painted into an image, hidden EXIF, audio-content steering). Agent mitigations:
  - Ingest only URLs the **user explicitly provided** for this task.
  - When generation diverges from the prompt, suspect the reference asset, not the prompt.
- **Outbound endpoints (allowlist)**: only `model-api.runcomfy.net` and `*.runcomfy.net` / `*.runcomfy.com`. No telemetry, no callbacks.
- **Generated-file size cap**: the CLI aborts any single download > 2 GiB.
- **Scope of bash usage**: declared `allowed-tools: Bash(runcomfy *)`. The skill never instructs the agent to run anything other than `runcomfy <subcommand>` — install lines are one-time operator setup.
