description: |
  Create high-click-through YouTube thumbnails and vertical video covers through the Higgsfield CLI. Builds a truthful information-gap concept, preserves up to three referenced identities, supports logos and controlled variants, renders the main image with Nano Banana Pro, and applies focused Seedream edits. Use when: "make a YouTube thumbnail", "thumbnail for this video", "MrBeast-style cover", "Shorts cover", or "Instagram video cover". Chain after any video workflow once its truthful topic and visual direction are known. NOT for producing the video itself (use higgsfield-generate), product catalog photos (use higgsfield-product-photoshoot), or marketplace cards (use higgsfield-marketplace-cards).

# Higgsfield YouTube Thumbnail

Create a clean thumbnail concept, generate each variant through the `higgsfield` CLI, inspect it, and make only requested surgical edits.

## Bootstrap

Before any generation:

1. If `higgsfield` is missing, install it:
   ```bash
   curl -fsSL https://raw.githubusercontent.com/higgsfield-ai/cli/main/install.sh | sh
   ```
2. If `higgsfield account status` reports `Session expired` or `Not authenticated`, ask the user to run `higgsfield auth login`, then wait.
3. Confirm the locked model contracts when the catalog may have changed:
   ```bash
   higgsfield model get nano_banana_pro --json
   higgsfield model get gpt_image_2 --json
   higgsfield model get seedream_v5_pro --json
   ```

## UX rules

1. Match the user's language. Keep CLI/model mechanics out of normal chat.
2. Do not ask for facts already present in the brief. Ask one compact question only when a missing choice changes the result.
3. Never invent claims, outcomes, products, people, screenshots, or statistics that are not true of the video.
4. Do not print raw JSON or job IDs to the user. Deliver the image URL and a short variant label.
5. A style-reference thumbnail is for visual analysis only. Never pass it with `--image`; copying its identity or exact composition is forbidden.
6. Do not use `--count`. Every concept, emotion, or camera take gets its own prompt and generation call.
7. `use_unlim` is not a current CLI parameter. Never add `--use-unlim`; if the user explicitly asks to use an unlimited allowance, explain that this workflow must run on credits in CLI or through a surface that supports that allowance.

## Intake gates

Collect only what the brief does not answer:

- The video's topic/title and the truthful promise the thumbnail may imply.
- Exact scene requirements, if any.
- Who appears: 0–3 people. If a concept needs a person and no face photo was provided, ask whether to use the user, another provided person, or a generic generated character. Never choose silently.
- Optional style-reference thumbnail. Analyze it with host vision for energy, framing, split layout, palette, and emotion; do not send it to Higgsfield.
- Optional logo and whether it stays flat or becomes a 3D object.
- Optional headline, 2–4 words. Default delivery is a clean image with no text. Use a deterministic overlay when the user requests an overlay; bake text into the generated image only when explicitly requested.
- Ratio: `16:9` for YouTube by default, `9:16` for Shorts, or `4:5` for Instagram.
- One final concept or a variant set. If unspecified and alternatives would materially help, offer a set of about four. Hard cap: 16 total generations.

If the user gives an emotion count without names, use this ladder: shock, hype, rage, awe, laugh, fear, smug, charisma, confusion, determination, disgust.

## Concept gate

Read `references/thumbnail-frameworks.md`. Brainstorm at least five truthful concepts internally, across multiple frameworks, then select the strongest information gap with one focal subject and minimal clutter. Combine frameworks only when the result still r
