Anthropic's Opus 5 prompting guide says existing Opus 4.8 prompts still work, but simpler ones may be better
The linked Claude docs explain behavioral differences and prompting patterns for Claude Opus 5:
- It is strongest on complex agentic coding tasks: multi-file features, larger refactors, and end-to-end feature work.
- It tends to finish full tasks instead of leaving stubs or placeholders.
- It also performs well on code review and bug finding, with high precision and recall.
- The guide emphasizes task scoping, subagent delegation, self-correction, verbosity control, and output artifacts when thinking is disabled.
- The post author says a previously over-engineered three.js agent skill pack now needs rewriting specifically for Opus 5 because the new prompting style is simpler.
