Security

1 high severity finding. You should review these findings carefully before considering using this skill.

High

W007: Insecure credential handling detected in skill instructions.

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

The prompt requires embedding user-provided HTML and "real data" verbatim into the generated output (screen divs), so any secrets included in that input would be emitted unchanged.

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

SKILL.md’s required runtime workflow explicitly embeds “用户提供的 HTML” into an on-page screen (an LLM-ingested free-text field at runtime), so an outsider who supplies that HTML/text can inject arbitrary content.

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 example HTML includes a runtime script tag that fetches and executes remote JavaScript from https://cdn.tailwindcss.com, which is loaded during skill runtime and the page relies on it to render Tailwind classes.
