Anthropic CCDV-F: Versioning Prompts for Claude Apps

Prompts often begin life as strings inside application code, then quietly grow into one of the most influential parts of the product. They define task boundaries, response structure, tool behavior, refusal rules, examples, and how retrieved evidence is interpreted.

If that text changes without an identifiable version, the team loses the ability to explain why two otherwise identical requests produced different behavior. A robust Claude development workflow treats prompts as deployable artifacts.
