He also called for the model to be less verbose while strongly adhering to instructions set in CLAUDE.md and repeated during a conversation, arguing that those instructions should persist rather than gradually being overridden by the model’s default communication style.

In the meantime, Patel, who said he has faced similar model drift at work, particularly while working with repositories involving a Jenkins, Python, Terraform, GKE, and Helm stack, pointed to a fix he and his team use when generating documentation and pull request summaries.

Rather than broadly asking Claude to be concise, his team uses explicit rules in project configuration to ban specific phrasings, because asking for conciseness can sometimes make the output shorter but more cryptic, Patel said.
