Finding

The manifest description says to use the skill 'when the user wants to optimize images for search engines and performance' and also matches a long list of common terms such as 'alt text,' 'image captions,' and 'image format.' Several of these phrases are broad enough to appear in routine conversations outside the intended SEO-skill context, and the file does not provide negative examples or exclusions to narrow activation.
