This surveys available blocks in your AEM Edge Delivery project and the Block Collection to give you the full palette before you start authoring. It scans local blocks, runs parallel searches for common ones like hero, cards, accordion, and carousel, then returns a consolidated inventory with purposes described in author terms. The timing matters here: use it when planning content structure or starting imports, not when you already know you need a specific block. It's basically replicating what authors see in their block library tools, so you make informed decisions about which blocks to use instead of discovering halfway through that a perfect-fit block existed all along.
