Returns the full latest serializable browser snapshot.
AI agents call get_dashboard_snapshot to retrieve information from Tanstack Start Devtools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries the current state of the browser/application dashboard via serialization. It has no side effects, does not modify data, does not execute arbitrary code, and does not delete or move resources. It is a read operation that returns a snapshot of existing state, making it the least risky category.
From the tool's definition Tool name and description indicate it 'Returns the full latest serializable browser snapshot' — a read-only retrieval operation that captures current state without modification or execution of code.
