-Mini-SWE-Agent Runner with Hermes Trajectory Format
+SWE Runner with Hermes Trajectory Format
 
-This module provides a runner that uses mini-swe-agent's execution environments
-(local, docker, modal) but outputs trajectories in the Hermes-Agent format
+A runner that uses Hermes-Agent's built-in execution environments
+(local, docker, modal) and outputs trajectories in the Hermes-Agent format
 compatible with batch_runner.py and trajectory_compressor.py.
 
 Features:
-- Uses mini-swe-agent's Docker, Modal, or Local environments for command execution
+- Uses Hermes-Agent's Docker, Modal, or Local environments for command execution
 - Outputs trajectories in Hermes format (from/value pairs with <tool_call>/<tool_response> XML)
 - Compatible with the trajectory compression pipeline
 - Supports batch processing from JSONL prompt files
