You're giving it too much credit. There's no master plan or secret depth to the word vomit Opus 5 was spewing. I suspect it's just the result of Anthropic optimizing other characteristics of the product like staying focused and covering edge cases in coding, which CC has definitely gotten way better at just in the last 6 months. The degradation in writing style was probably an unintended side effect of other optimizations they were making. Admittedly it works okay for internals, and has the side effect of increasing token spend, but I am 100% sure that it could reduced by 90-99% without losing ANY signal, if there was just some better heuristics for what to say where (tech spec, inline comment, commit message, CLAUDE.md, PR should have different things) and better judgement for what to distill to represent at different zoom levels.

But that assumes this is a net improvement on linguistic efficiency rather than an artifact. Given that they tried to RL away from this style in 5.1 I'm not terribly bullish of Claudlish becoming something people try and learn. It being dense is less the issue than it being vacuous (as another commenter mentioned here). It's just very unclear and ambiguous writing. I think it has no place anywhere that needs language to be put to productive use.
