 ## What This Is
 
-ClawBench is a benchmarking framework for evaluating AI web agents on 153 real-world online tasks spanning 144 live websites and 15 life categories. Each task runs in an isolated Docker container with Chromium, a recording Chrome extension, and an AI agent (OpenClaw). The framework captures five layers of data: session replay (MP4), action screenshots, HTTP traffic, browser actions, and agent messages.
+ClawBench is a benchmarking framework for evaluating AI web agents on 153 real-world online tasks spanning 144 live websites and 15 life categories. Each task runs in an isolated Docker container with Chromium, a recording Chrome extension, and an AI agent harness (`openclaw` or `opencode`, selectable via `--harness`). The framework captures five layers of data: session replay (MP4), action screenshots, HTTP traffic, browser actions, and agent messages.
