Most static findings are false positives from Markdown backticks, JavaScript syntax, or visual-design prose. The remote installer uses an unpinned curl-to-shell command, while local references and Google Fonts create disclosed third-party transfers. No prompt injection or covert exfiltration intent was found.

SKILL.md:20
Pipe to shell pattern
curl -fsSL https://raw.githubusercontent.com/higgsfield-ai/cli/main/install.sh | sh
The bootstrap command pipes a remotely downloaded, mutable script directly into sh. A compromised repository or changed script would gain immediate shell execution.

Automatic Third-Party Upload of Local Images
Face photos and logos supplied as local paths are automatically uploaded to Higgsfield. These potentially sensitive assets leave the local environment.
The skill explicitly states that local paths are auto-uploaded and describes retrying a downloaded image as an uploaded media input.

Hardcoded URL
curl -fsSL https://raw.githubusercontent.com/higgsfield-ai/cli/main/install.sh | sh
The URL points to a mutable installation script on a remote GitHub branch. No commit hash or integrity check pins the code that will execute.

Hardcoded URL
<link href="https://fonts.googleapis.com/css2?family=Anton&display=swap" rel="stylesheet">
The HTML preview loads Anton from Google Fonts, creating a real third-party network request. This is expected functionality but exposes the user's IP address to the font provider.

Hardcoded URL
fontLink.href = 'https://fonts.googleapis.com/css2?family=Anton&display=swap';
The canvas workflow dynamically loads Anton from Google Fonts before rendering. This expected dependency creates a third-party request and a minor privacy and availability risk.

作成できるもの

Launch a YouTube Video

Create several truthful 16:9 thumbnail concepts with clear focal subjects and strong mobile readability.

Prepare Vertical Covers

Generate 9:16 Shorts covers or 4:5 Instagram covers while keeping faces in readable positions.

Maintain Brand Consistency

Use face references, logos, controlled variants, and focused edits across a recurring video series.

これらのプロンプトを試す

Create a Basic Thumbnail 
Create a truthful 16:9 YouTube thumbnail for a video titled "[title]" with one clear subject and no text.
Create Concept Variants 
Create four distinct 16:9 concepts for "[topic]" using [face image], while preserving identity and avoiding unsupported claims.
Create a Vertical Cover 
Create a 9:16 Shorts cover for "[topic]" with the face in the upper two-thirds and a two-word overlay.
Direct a Branded Variant Set 
Create four branded variants for "[topic]" using [face images] and [logo], varying only concept, expression, and camera direction.

ベストプラクティス

  • Provide the exact video promise, required scene details, target ratio, and approved reference images.
  • Keep one focal subject and verify that the concept remains readable near 120 pixels wide.
  • Review every result for truthful claims, identity accuracy, stray text, watermarks, and exact headline spelling.

回避

  • Do not imitate a reference thumbnail's identity or exact composition.
  • Do not request unsupported claims, invented statistics, false screenshots, or misleading outcomes.
  • Do not combine many subjects, props, labels, and effects into one crowded thumbnail.

よくある質問

Which image ratios are supported?
Use 16:9 for standard YouTube thumbnails, 9:16 for Shorts, and 4:5 for Instagram covers.
Can the skill preserve a person's identity?
It can use supplied face references and detailed identity instructions, but every result still requires visual review.
Can it add headline text?
Yes. It supports deterministic HTML canvas overlays or explicitly requested text baked during image generation.
Does it create multiple variants?
Yes. It makes separate generation calls for distinct concepts, expressions, or camera directions, with a maximum of 16 generations.
What external services are required?
The workflow requires an authenticated Higgsfield account. Google Fonts is also used by the documented overlay examples.
Are local images kept on the device?
No. Local face and logo paths are automatically uploaded to Higgsfield when used as generation inputs.
