Thanks; the issue likely stemmed from the translation software used previously. I’ve seen many people online mention that removing skills like "superpowers" reduces token consumption and shortens completion times. I also read that Anthropic removed over 80% of the system prompts for Claude Code. I’m interested in finding out how to adjust `claude.md` and the installed skills to better optimize performance for the Opus 5 and Fable 5 models.
