E004: Prompt injection detected in skill instructions.

What this means

Detected a prompt injection in the skill instructions. The skill contains hidden or deceptive instructions that fall outside its stated purpose and attempt to override the agent’s safety guidelines or intended behavior.

Why it was flagged

The skill is a legitimate image-SEO audit and optimization guide, but its batch exiftool command uses `-overwrite_original` on wildcard globs, which permanently alters the user's original image files without a backup or confirmation step, a careless destructive action.

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

The required workflow runs `parse_html.py --url <url>` on a user-supplied or arbitrary web page and ingests its alt text and attributes, which is outsider-authored text the agent must actively fetch, so this is low exposure; the optional DataForSEO image SERP path adds search-result text the agent also fetches on demand.
