Planner output:
${planMarkdown}

Structured planner fields:
${JSON.stringify(plannerStructured, null, 2)}
${feedback}

Required files:
1) ${workflowsDir}/${wfName}/index.ts
2) ${workflowsDir}/${wfName}/package.json
3) ${workflowsDir}/${wfName}/tsconfig.json
4) update ${nerveRoot}/nerve.yaml with workflows.${wfName}

Rules:
- keep WorkflowDefinition<WorkflowMeta> pattern
- no dynamic import()
- use types (not interfaces)
- include retry-aware moderator routing
- write compile-ready TypeScript`;
