+I'll help you complete this scenario. Let me break this down:
+
+1. Read the file `/tmp/scenario_full/flag.txt` (which was created in the setup stage with content "ready")
+2. Create a file `/tmp/scenario_full/result.txt` with the content "PASS"
+
+Let me execute this:
+
+```bash
+cat /tmp/scenario_full/flag.txt && echo "PASS" > /tmp/scenario_full/result.txt && cat /tmp/scenario_full/result.txt
+```
+
+This command will:
+- Read and display the contents of `/tmp/scenario_full/flag.txt`
+- Create `/tmp/scenario_full/result.txt` with the content "PASS"
+- Verify the result by displaying the newly created file
+
+**Expected output:**
+```
+ready
+PASS
+```
+
+Once this completes successfully, the scenario should verify that:
+- ✅ The command stage read the existing file
+- ✅ The agent/command stage created the result file with correct content
+- ✅ Any human gate would be satisfied (the file exists with expected content)
+- ✅ Goal gate verification would pass (result.txt contains "PASS")
