When Claude Code reads a large file or runs a noisy command, winnow splits the result into small blocks and asks Jev, in one call, whether each block matters for the current task.
Blocks Jev is confident are not needed are swapped for a short stub with a one-paragraph summary and a key to restore the full text. Nothing is thrown away, it just stops costing tokens until you ask for it.
Uses Jev by default, with a fallback that runs on Claude Haiku while Jev is in early access.
