write-preview

When the agent writes a file, you see the full content streaming in line by line — not just “Successfully wrote 2.4KB to path.” After completion, the content stays visible with a summary line.

The LLM receives the standard short confirmation (it already knows what it wrote). Only the visual display is enhanced.

Why it matters: New file creation is one of the most consequential agent actions. Write-preview lets you read the generated code as it lands, catching issues before the agent commits and moves on.
