+
+## Verification
+
+After each flow completes, verify the side effects — not just the TUI output:
+
+- If a project was created: use `shell` to check the directory exists and contains expected files (e.g.
+  `agentcore.json`)
+- If a resource was added: use `shell` to check the config file was updated
+- If a command produced output: verify the output matches expectations
+
+Do not rely solely on what the TUI displays. Confirm the CLI actually did what it claimed.
