Have a way of validating the workspace before and after a command

We should know how to run tests for the project, this would allow the following:

1. Some commands may require tests to be passing before they run;
2. We could have a command to fix tests. It would run the verification script and include test results in the prompt;
3. We could run tests after a command execution and either reject the change, or reuse logic from 2 to attempt to fix the issue;
