I disagree. The rigidity of YAML and stuff like that is what actually makes LLMs work better. I have strict linting rules and file size limits and it imposes discipline on LLMs. That's why it worked even last year. Even before Opus 4.0 it worked to some extent as long as you imposed discipline on these models Trust me, I do pretty complicated things with Ansible, key thing is to have decent established patterns and these models truly are getting better.
