Show HN: Jevia – An outcome-based model router for coding agents

Jevia launched as an outcome-based model router for coding agents that routes a task to a model tier and uses verified outcomes to improve future decisions. The tool installs as a prebuilt binary without Rust or Cargo, adds a reviewable .jevia/config.toml via 'jevia init', keeps credentials in the environment outside config, and validates config, storage, credentials and one live request with 'jevia check'. Jevia returns a model tier, confidence and traceable run ID from 'jevia route' and runs Codex, Claude Code, OpenCode, Gemini CLI, Cursor Agent, Copilot CLI, Aider, Goose, Amp or any configured command-line agent.
