The only thing a model can output is tokens; to achieve this, a tool of converting tokens into operational transformations is required. For example, I have an ast-grep skill, it will instruct the model to generate ast-grep rules and run ast-grep to perform file modifications.

I am saying to directly output the operational transformation instructions as the tokens. You’re essentially telling it to “write the diff” and then applying the patch.
