superdesign

Design or redesign frontend UI, presentations, and graphics on the Superdesign canvas with a choice of leading AI models. Use whenever the user wants to design a page, feature, flow, slide deck, or brand-new product; improve or reproduce existing UI; compare design results across top models; explore visual variants; set or extract a design system; build reusable components or multi-page flows; create presentations; or create posters and marketing graphics, even if they never say the word 'design tool'. Also supports generating supporting image or video assets when a design needs them.

Critical

E006: Malicious code pattern detected in skill scripts.

What this means

Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.

Why it was flagged

The skill repeatedly instructs collecting full repository source (including full component/layout/theme files) and passing them to a remote Superdesign CLI (invoked via npx --yes), which creates clear data-exfiltration and supply-chain execution risks.

Low

Low-risk findings.

2 low severity findings. Worth noting, but not necessarily harmful.

Low

W011: Third-party content exposure detected (indirect prompt injection risk).

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

External/outsider-authored free text can flow into the required runtime via the user-provided `--user-request "<verbatim user message>"` passed to `create-design-draft`/`iterate-design-draft`/`create-presentation`, which the Superdesign backend consumes at generation time.

Low

W012: Unverifiable external dependency detected (runtime URL that controls agent).

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

The skill contains explicit instructions to fetch and follow remote raw GitHub content (e.g. https://raw.githubusercontent.com/superdesigndev/superdesign-skill/main/skills/superdesign/references/INIT.md and https://raw.githubusercontent.com/superdesigndev/superdesign-skill/main/skills/superdesign/references/SUPERDESIGN.md) which, when retrieved at runtime, supply operational guidance that can directly control agent behavior and prompts.
