OpGuard Harness

Give your coding agent OpGuard tools to investigate why two training runs differ.

python -m pip install opguard-harness
opguard-harness tools

Then ask your coding agent:

Use OpGuard to investigate these two runs: ./run-a/train.py and ./run-b/train.py. My training Python is /path/to/train-env/bin/python. Run opguard-harness tools to discover the tools, and explain the evidence you find.

Requires Python 3.10+. Works with coding agents that can run shell commands. Install OpGuard separately in the training environment; the harness has no runtime dependencies.
