What this is: a single-file CLI and a matching agent skill that give any coding agent
(Claude Code, Codex, OpenCode) a fast, cheap, calibrated second opinion. The agent stays the
reasoning model; jev answers the narrow, repeated judgments (is this relevant? which
bucket? how severe? does the source support this claim?) so the agent never has to read a
thousand items into its context window or trust its own uncalibrated confidence.
Why it exists: LLM agents are expensive and inconsistent at high-volume judgment calls, and they cannot tell you how sure they are. A decision model that returns a real
