 The example shows placement, not required values.
-Use `metadata.role: 'driver'` only when this child should author and supervise descendants.
-Omit that role for a leaf.
+Replace the example skill content with the exact bytes the parent received.
+Declare `tools.agent_runtime_coordination_spawn_worker: true` only when this child can create descendants.
+That declaration is the recursion signal; names, descriptions, prompts, and metadata never grant authority.
+Every profile with spawn authority must carry the complete authoring skill in `resources.skills`.
+Also declare every other coordination or work tool the child needs by its visible name.
+Omit spawn authority and the authoring skill for an ordinary leaf.
 
 The task argument names the concrete artifact and a check that can fail.
 The profile names how the agent works and which capabilities it receives.
