Several product teams will build Claude features on your platform architecture. In earlier projects, teams skipped output validation and wrote prompts containing customer data to logs without redaction. What is the most effective form of implementation guidance?

Answer: D — Provide a reference implementation and shared libraries that validate and redact by default, with reasons

(d) is right: guidance that makes the safe path the default, plus documented non-negotiables and their reasons, scales across teams. (a) relies on memory and honesty, which is how the earlier gaps happened. (b) makes the architect a bottleneck and doesn't scale. (c) confuses model instructions with engineering controls; the model can't redact your logging pipeline.
