Think pytest only outputting OK if all tests pass, but in case of error getting the necessary error output only.
It is a cli, basic use for agents:
oo pytest oo cargo test etc…
Custom patterns configurable and there is also learn -flag to use Anthropic models to have LLM write the configuration for your custom command.
Nothing too complicated or special, but works in my LLM workflow saving on token use & speeding models!
Have a great weekend!
