workflow-builder

workflow-builder is a Workflow automation & no-code skill for AI agents, published by n8n-io in the n8n repository on GitHub. Skillspace rates workflow-builder F (45/100) and the safety scan rated it risky; the rating is based on static analysis only.

Load before calling build-workflow. Default path for all single-workflow work: new one-off workflows, existing-workflow edits, verification repairs, and workflow-local data tables. Write or edit a workspace source file, run workflow-sdk validate via workspace_execute_command, then call build-workflow with filePath. When the workflow creates or writes Data Tables, load data-table-manager first, then this skill. Do not load planning or create-tasks first. Load planning only when multiple coordinated workflows or shared cross-task data tables require a dependency-aware task graph.
