From an output to the next decision
How AI Handoff connects the toolkit.
Work through a tool, review its results, then open AI Handoff in the final step. Your inputs, selections and calculated outputs travel together, so an assistant receives the actual session rather than a screenshot to interpret.
Choose a task-specific prompt, agent instructions, exact JSON, Markdown or MCP-shaped context. Review and export locally, or explicitly choose the optional AI drafting connection.
