What it is
A Claude Code plugin for developers that uses TypeSafe's Jev to prune noisy Bash stdout after a command runs but before the result reaches the main LLM, reducing tokens carried into later turns without generating a summary.
How it uses Jev
A tool.call hook wraps the Bash tool's next() result. Jev receives { context, task, history, command, chunks } and one noul question per chunk: does any line in this chunk need to remain available? Chunks scoring at least keepThreshold or above 0.1 are kept; dropped runs become [N lines omitted].
Primitives:noul
Technique worth stealing
Gate output by an estimated-token floor, then ask Jev one noul question per chunk against partitioned history segments.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
