What it is
jselect is a Python tool and package that selects relevant, source-linked passages from files, records, or agents, assembling a context within a token budget for AI agents. It is separate from jgrep.
How it uses Jev
jselect uses Jev Noul relevance judgments to score passages against a task. The result is used to select a diverse set of excerpts, which are assembled into a context with citations. Without credentials, it falls back to local lexical retrieval.

Technique worth stealing
Diversity-aware selection of source-linked evidence within a token budget.
Try it
uv tool install jev-select; jselect "task" data.jsonl --tokens 8000
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.
