Benefits of Using Plan Mode
Using 'Plan Mode' can improve output quality by at least 20%. It gives the AI space to plan before acting, allowing you to review its steps beforehand instead of letting the AI modify the codebase impulsively.
UltraThink Usage Tips
While 'ultrathink' may consume more tokens and take longer (up to twice as long), it is highly effective for difficult logic problems. Use this keyword in 90% of your messages if you want higher accuracy.
Visual Differences
Unlike Cursor, which has a very detailed plan display on the left side, Claude Code features a simpler interface that remains effective for the review and approval process.
