Extended Thinking Mode

Claude's extended thinking shows you the reasoning process:

"Let me analyze this folder structure. I see 847 files in Downloads. Categorizing by extension: 234 PDFs (likely documents), 156 images (jpg/png), 89 zip archives... The PDFs contain dates in their filenames following YYYY-MM-DD format, suggesting they should be organized chronologically..."

This pairs perfectly with Ishi's Glass Box — you see why Claude makes decisions before executing.
