Efficiency Guidelines

Avoid Unnecessary Waits

❌ browser_snapshot after every action
✅ Use action return values for next step

Parallel Preparation

✅ Prepare all tweet content before browser operations
✅ Copy to clipboard while navigating

Sequential Execution

Navigate → Paste first tweet → Add tweet → Paste → ... → Save
