GoKawiilAnthropic publishes usage guide for Claude's Opus 5.5 model
Anthropic released a guide explaining how to work with its Opus 5.5 model in Claude apps and Claude Code. The guide says Opus 5.5 now reasons before every response automatically, can run longer on multi-step tasks with less oversight, and recommends users state a clear 'done' condition up front rather than micromanaging each step. It also advises dropping older prompt habits like telling the model to 'think carefully,' since that behavior is now built in.
