Anthropic just published a guide to using Opus 5.5. It tells you to delete "think carefully" from your prompts. You can ask Opus 5.5 to use it to review the old rules in your project. It already thinks before every reply, and it decides how much. Delete that line and replies start sooner, with no drop in quality. If your CLAUDE.md still says "take a deep breath" or "IMPORTANT: think hard," delete those too. Send this prompt and the link below to Opus 5.5 👇 "Read this guide and review my project's CLAUDE.md, AGENTS.md, skills, and saved prompts. Find three kinds of problems: lines that push you to think more, like 'think carefully' or 'take a deep breath'; rules and prompts that hand out tasks one step at a time or don't define what done looks like; and rules that make you stop for confirmation when you don't need to. For each issue, quote the original instruction, explain its impact, and suggest the smallest change needed. List any approval rules involving safety, permissions, or destructive actions separately for me to decide. Also suggest adding one rule: at the end of every long run, report under three headings: Blocked on me, Changed, Found. Show me the recommendations first. Don't modify anything yet."
