RATE LIMIT EFFICIENT: This is the most API-efficient tool for multiple block operations. Combine all create/update/delete operations into a single call whenever possible. For intensive page updates or revisions, prefer this tool over multiple sequential calls.

Executes a sequence of low-level block actions (create, update, move, delete) in a single, non-transactional batch. Actions are executed in the provided order.

UID Placeholders for Nested Blocks: Use {{uid:name}} syntax for parent-child references within the same batch. The server generates proper random UIDs and returns a uid_map showing placeholder→UID mappings. Example: { uid: "{{uid:parent1}}", string: "Parent" } then { location: { "parent-uid": "{{uid:parent1}}" }, string: "Child" }. Response includes { success: true, uid_map: { "parent1": "Xk7mN2pQ9" } }.

For actions on existing blocks, a valid block UID is required. Note: Roam-flavored markdown, including block embedding with ((UID)) syntax, is supported within the string property for create-block and update-block actions. For actions on existing blocks or within a specific page context, it is often necessary to first obtain valid page or block UIDs. Tools like roam_fetch_page_by_title or other search tools can be used to retrieve these UIDs before executing batch actions. For simpler, sequential outlines, roam_create_outline is often more suitable. IMPORTANT: Before using this tool, ensure that you have loaded into context the 'Roam Markdown Cheatsheet' resource.
