Until Opus 5.0 I'd have agreed with you, but Opus 5.5 is honestly one of the best I've ever sparred with, vastly better than the rest, including Astra imho. Especially so when prompting for clear top-down, first-principles communication.
The ‘concise’ output style setting is bad with Opus 5.5, as it will often spit out a cryptic (is this really English?!), allergic-to-commas concise response, which takes more time to parse.
< mundane detail>
< If you don't run this command your computer will explode>
< exposition >
< mundane reminder to follow up something else >
Then 3 back and forths later, your computer explodes, and claude has the cheek to point out when questioned that it did warn you.
