 ## Summary
 
-Both files were successfully read:
+**README.md:** Contains minimal information describing this as a "Test Project" created for testing parallel subagent display functionality in coven.
 
-**README.md**: Contains a brief project description. It's titled "Test Project" and describes itself as "a minimal project for testing parallel subagent display in coven."
+**notes.txt:** Contains a single line indicating this is test notes for a parallel subagent test case.
 
-**notes.txt**: Contains a single line of test notes stating: "These are test notes for the parallel subagent test case."
+Both files appear to be part of a test setup for the coven system's parallel subagent feature.
 
-Both files are minimal, as expected for a test project setup.

-Done! The subagent successfully made parallel Read calls to both files:
-- **README.md** was read successfully (contains "# Test Project" and description text)
-- **nonexistent.txt** returned an error as expected (file doesn't exist)
+Done! The subagent successfully read both files in parallel:
 
-Both Read calls were executed simultaneously in a single function_calls block.
+- **README.md**: Contains "Test Project" - a minimal project for testing
+- **nonexistent.txt**: File does not exist (returned an error as expected)
 
+The agent made both Read tool calls simultaneously in a single block, as requested.
