  Build a complete non-photoreal narrated explainer or story video from
  ordered 10-second blocks: one narrator, one universal style key, one Seed
  Audio take and one Gemini Omni clip per block, then server-side assembly
  with explainer_video. Use when: "make an explainer video", "explain this in
  a video", "turn this topic or document into a narrated video", "tell this
  story as an animated video", "make a faceless narrated video", or "show me
  explainer styles". Supports live CMS presets, custom style references,
  mascot/faceless modes, two aspects, and optional burned subtitles. NOT for:
  photoreal films, ads/UGC, talking heads, podcasts, motion typography reels,
  one-off clips without narration, or editing a finished video.

# Higgsfield Video Explainer

Run the MCP video-explainer workflow through Higgsfield CLI. Lock one visual style key, write one narration line and one matching visual prompt per 10-second block, generate every voice take first, generate every clip second, then immediately assemble the ordered pairs with `explainer_video`.

Never use the monolithic `video_explainer` job in this skill.

## MCP-to-CLI mapping

| MCP workflow operation | CLI equivalent |
|---|---|
| `get_explainer_presets` | `higgsfield preset list video-explainer --json` |
| `resolve_explainer_preset` | `higgsfield preset resolve video-explainer <preset_id> --json` |
| `generate_image` / `nano_banana_pro` | `higgsfield generate create nano_banana_2 ...` |
| `list_voices` | `higgsfield voices list --json` |
| `generate_audio` / `seed_audio` | `higgsfield generate create seed_audio ...` |
| `generate_video` / `gemini_omni` | `higgsfield generate create gemini_omni ...` |
| `job_status` | `--wait --json` or `higgsfield generate wait <job_id> --json` |
| `explainer_video` | `higgsfield generate create explainer_video ...` |

`nano_banana_2` is the public CLI id for the Nano Banana Pro style-key model used by the MCP workflow.

## Bootstrap

1. If `higgsfield` is unavailable, install it:

   ```bash
   curl -fsSL https://raw.githubusercontent.com/higgsfield-ai/cli/main/install.sh | sh
   ```

2. If `higgsfield account status` fails, ask the user to run `higgsfield auth login`, then wait.
3. Inspect the live contracts before the first submission:

   ```bash
   higgsfield model get nano_banana_2
   higgsfield model get seed_audio
   higgsfield model get gemini_omni
   higgsfield model get explainer_video
   ```

## Phase 0 — ask first

Collect choices in two separate turns, in this order. Never merge them.

### Turn 1 — style only

Always load the live CMS catalog:

```bash
higgsfield preset list video-explainer --json
```

Show the preset names with their thumbnail/video preview URLs. Say one short line asking the user to pick a preset, describe a custom style, or attach style-reference images, then end the turn. Do not ask production questions in the same turn. Choosing a style is mandatory; never choose silently unless the user explicitly says “you choose.”

Skip this turn only when the request already contains `explainer preset id: <uuid>`. Confirm that UUID exists in the live catalog and keep it for Phase 1.

### Turn 2 — production settings

Only after style selection, collect every unresolved setting:

- Duration: one to ten whole minutes. `N = duration_minutes × 6` fixed 10-second blocks.
- Narration language: English by default, but still offer the choice.
- Character: recurring mascot or faceless stylistic scenes. Always ask.
- Aspect: `16:9` by default or `9:16` vertical.
- Subtitles: off by default. Explain that subtitles cost 0.05 credit per voiced block. If enabled, make the user choose `patrick`, `caveat`, `marker`, or `anton`; never choose silently.

Every choice belongs to the user unless they explicitly delegate it.
