What it is
SemDecide is a CLI for Unix pipelines and CI that turns text or JSONL into semantic predicates, routes, scores, and filtered streams, with stable exit codes, for shell scripts and automation.
How it uses Jev
Jev makes the semantic judgments: whether text satisfies a predicate, which named option fits, how a rubric level scores, or which JSONL records match. SemDecide wraps these typed decisions with input limits, retries, thresholds, uncertainty margins, JSON schemas, and grep-like exit codes.
Primitives:choicescorenoul
Technique worth stealing
Wrap typed model decisions in Unix-style commands with stable JSON output, thresholds, and distinct exit codes for true, false, uncertain, and provider failure.
Try it
pipx install the v0.2.1 wheel, export TYPESAFE_API_KEY, then pipe text into semdecide is.

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.
