Shev turns any message into a single JSON decision with no agents or prompt engineering

DeepSeek v4.1 flash on OpenCode pretty good

Shev is a command-line tool that takes a whole message—an email, ticket, or review—and returns one structured JSON decision with fields like actionable, take_action, confidence, and generated_response. It runs locally on Apple Silicon with a small ternary MLX model or remotely via DeepSeek, and saves every decision to responses.json for other assistants to read over MCP. No agents, no orchestration, no prompt engineering.
