Addy Osmani's Opus 5.5 playbook: hand over whole tasks, drop 'think carefully' prompts
ClaudeDevs · x · 2026-09-23
Addy Osmani published a playbook for Opus 5.5 in Claude and Claude Code. Key tips: hand over the whole task in one message with a clear finish line and stop conditions (the model's biggest gains are on long multi-step work, running for hours unsupervised); delete "think carefully"-style prompts since Opus 5.5 thinks before every reply; and after a long run, read what it needs from you before continuing.
