Try these in your first Opus 5.5 session:
→ Hand over a whole task. Define "done" and when to check in.
→ Drop "think carefully". It always thinks first.
→ After a long run, check what it needs to go further.

Anthropic's tip for Opus 5.5: hand it a whole task rather than breaking it into steps, but explicitly define what 'done' looks like and when it should check back in.
Skip prefacing prompts with 'think carefully' — Anthropic says Opus 5.5 always reasons before answering, making the instruction redundant with its default behavior.
After a long autonomous run, ask Opus 5.5 directly what it needs to keep going rather than guessing, per Anthropic's own usage playbook.
