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. Don't use this skill for explicit one-off tasks that can be done by a single node execution: load one-off-operations and run the node with nodes(action="execute"). Also load for a workflow's evaluations, model choices, credential setup, and post-build verification: this skill lists the references for those steps.
