Author of loop-engineering (11.5k★). cobusgreyling.com 4 skills 140 South Africa Synced 14 days ago [GitHub](https://github.com/cobusgreyling) [Website](https://www.cobusgreyling.com) ## Skills ### [cobusgreyling/jev](https://skilld.dev/gh/cobusgreyling/jev) Unofficial TypeSafe Jev showcase — System One decisions, not chat. 4 skills 140 `npx skilld add cobusgreyling/jev --all` - [/jev](https://skilld.dev/gh/cobusgreyling/jev/jev) Use TypeSafe Jev for typed judgments (Choice, Score, Noul) instead of asking a chat model to classify. Pair with a generative model for prose. Use when classifying, routing, scoring, guardrailing, or the user runs /jev. - [/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. - [/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\`. - [/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\`. Curated skills from @cobusgreyling.
