Bug Description
prompt: "write me an absolutely minimal powershell (5.1 compatible) script that takes two text files, one with a 'hostname' per line, and one with a domain per line, and tries to resolve each combination, writing the successes to an output file."

Opus 5 (1M context)'s safeguards flagged this message.

Overzealous downgrade for a benign and trivial system ops request that could be done effectively with dozens of models, though I note plenty of unnecessary code was produced by Opus 4.8 (e.g. not "absolutely minimal"). Even Qwen 3.6 35B A3B running locally came up with a well formatted working solution using 23% fewer bytes (after removing excess whitespace from both solutions).
