Example use cases
Extract product guide sidebars

“From this HTML I'm pasting, extract all aside blocks where the attribute 'class' equals 'callout-warning' and the content mentions 'deprecated' — I need the structured list of those warning boxes.”
Deduplicate aside content across crawls
“Fetch aside blocks from https://blog.example.com/article/2024-review that have attribute 'role' equal to 'complementary' and include the term 'tip', but skip any that match these texts I already collected: ['Use our newsletter to stay updated', 'Subscribe for more tips'].”
