About
jevpipe is a Unix-style command-line filter that pipes text, files, or records into a fast 'System 1' decision model called Jev and returns typed, structured judgments instead of free-form prose. It lets an AI agent offload bulk classification or judgment calls over thousands of items to one shell command rather than reading and reasoning over each item itself.
At a glance
jevpipe applies the same model judgment to many lines or records and returns the results through a CLI. It is worth evaluating if you need semantic filtering that is hard to express as a fixed pattern.
Good fit
Developers classifying approved logs, commit messages or structured records with a repeatable prompt.
Consider something else when
Use deterministic checks when every match must be found or the data cannot go to a model provider.
Start here
Label a small synthetic input file with borderline examples. Run one filter and compare its misses and false matches with your expected results before increasing volume.
Cost and requirements
The documented setup uses an OpenRouter or TypeSafe API key. Calls may incur provider charges.
Limits to know
The CLI sends task input to the selected provider. Model outputs need checking, especially if results trigger downstream actions.

Why it made the leaderboard
It lets an agent classify or judge thousands of files or records in one shell command via a cheap 'System 1' model, so the expensive orchestrating model doesn't have to read everything itself.
