Even Fable is done with Opus' verbosity...

A user on reddit.com observed that their Fable agent, which utilizes Opus sub-agents, has started adding "Then reply with ONLY (under 15 lines):" to every prompt. This behavior suggests that even Fable is attempting to manage or reduce the verbosity of Opus, highlighting a potential common challenge with the output length of the Opus model.

This report uniquely highlights a practical workaround for Opus's verbosity, unlike theoretical discussions, by showing Fable's direct intervention in prompt engineering.
