Swap Component Instance and Override Strategy

Overview

Transfer content and property overrides from a source instance to one or more target instances in Figma, maintaining design consistency while reducing manual work.

Step-by-Step Process

1. Selection Analysis

• Use get_selection() to identify the parent component or selected instances
• For parent components, scan for instances with: scan_nodes_by_types(nodeId: "parent-id", types: ["INSTANCE"])
• Identify custom slots by name patterns (e.g. "Custom Slot*" or "Instance Slot")
• Determine which is the source instance (with content to copy) and which are targets

2. Inspect Source Instance

• Use get_node(nodeId: "source-instance-id") to examine the source instance structure
• Use get_nodes_info(nodeIds: [...]) to batch-inspect multiple instances
• Use scan_text_nodes(nodeId: "source-instance-id") to capture all text content
