-### Install the harness
+First, we will clone the harness and start KCoral on the GPU server. On the
+agent machine, `evolution/setup.py` then creates a task worktree and Python
+environment with the required packages, skills, and prompt. We will check the
+baseline through KCoral before launching the agent in that worktree.
 
-The environment running the agent needs Python, Rust, and `uv`. The GPU server
-needs CUDA and, for NCU profiling, Nsight Compute.
+### Prepare the harness checkout
+
+Use Linux x86_64, Python 3.12 or 3.13, and pip 25.1+ on both machines.
+The agent machine needs `uv`, Rust 1.89+ with Cargo, C/C++ build tools, and
+Python development headers; the GPU server needs CUDA and a compatible driver.
+For profiling, install Nsight Compute on both machines.
 
 Clone the harness where the agent runs and on the GPU server. If they share
 one machine, a single checkout is enough:
 
 ```bash
-git clone https://github.com/mlc-ai/TIRx-harness.git
+git clone --recursive https://github.com/mlc-ai/TIRx-harness.git
 cd TIRx-harness
-git submodule update --init thirdparty/tvm-rust-ext
