+|---|---|
+| Writes code manually | Writes prompts & workflows |
+| Reviews PRs | Reviews agent outputs |
+| Runs CI/CD pipelines | Orchestrates AI agents |
+| Debugging code | Debugging agent behavior |

+# Agentic Human Processes
+
+## Humans and AI collaborate at every stage
+
+- **Author** — Write natural language workflows
+- **Reviewer** — Approve plans and validate outputs
+- **Supervisor** — Monitor running agents and handle exceptions
+- **Debugger** — Diagnose workflow behavior and improve prompts
+
+> The human stays in the loop while AI handles execution
