Hi @david-mamani, I'm from the Sealos team. This is a brilliant implementation of Track G! I especially love the MockLLM approach for reproducibility and the focus on CLI for transparency. Would love to feature this as an official use case. Do you have a Twitter or Discord where we can chat further?
