I have a template I use with generated python projects that sets up all the test info first.

I start the coding session in a directory where I've already set this up and maybe drafted a README.md, and usually it just automatically starts running the `make check` without prompting.

I've also used it for migrating old code. I put an old python 2 script in src and asked it get make check to work, and it even added test on its own initiative.

I'm mostly using Qwen3.6 (now Qwen3.7) running on my DGX Spark in llama.cpp using different harnesses, or the default model on opencode.
