Pair with a generative model for prose. Use when classifying, routing, scoring, guardrailing, or the user runs /jev. Updatedlast month [/jev-fanout](https://skilld.dev/gh/cobusgreyling/jev/jev-fanout) Ask every independent TypeSafe Jev question in one POST /v1/systemone (speculative fan-out). Use for parallel questions, smart-home or compound commands, one-call turn assessment, or when the user runs /jev-fanout. Do not fire one HTTP call per question. Updatedlast month [/jev-guardrail](https://skilld.dev/gh/cobusgreyling/jev/jev-guardrail) Screen LLM input and output with TypeSafe Jev Noul hazard batteries plus a harm Score; policy in code returns pass, review, or block. Use for jailbreak, prompt injection, secret leak, denylist pressure, or when the user runs /jev-guardrail or \`npx jev guard\`. Updatedlast month [/jev-route](https://skilld.dev/gh/cobusgreyling/jev/jev-route) Route with TypeSafe Jev — map Choice plus confidence to act/confirm/human, or pick a coding-agent model tier. Use for confidence routing, model routing, cheap vs frontier, loop-jev, or when the user runs /jev-route or \`npx jev route\`.
