List all saved snapshot bookmarks.
AI agents call sdk_list_bookmarks to retrieve information from UI Bridge MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of existing bookmarks without modifying, creating, or deleting any data. It is a read-only operation with minimal security impact, as it only exposes previously saved snapshots that are already stored in the system.
From the tool's definition Tool name 'sdk_list_bookmarks' and description 'List all saved snapshot bookmarks' indicate a retrieval operation with no side effects.
