How it Works
How it Works As n8n instances scale, teams often lose track of sub-workflows—who uses them, where they are referenced, and whether they can be safely updated. This leads to inefficiencies like unnecessary copies of workflows or reluctance to modify existing ones. This workflow solves that problem by: Fetching all workflows and identifying which ones execute others. Verifying that referenced subworkflows exist. Building a caller-subworkflow dependency graph for visibility. Automatically tagging
