# disler/ten-levels-of-jev > A lab of ten levels showing how to use Jev (TypeSafe System One) for typed, probabilistic decisions in code and inside the pi coding agent, from a single yes/no gate to agent-chosen questions. - Magnitude: 4.6 out of 10 — Early signal - Stars: 101 total · +34 stars today, ≈ 42 by evening - Star trust: star growth looks organic - Category: AI agents · Language: TypeScript · License: MIT · Created: 2026-09-27 · Last push: 2026-09-27 - GitHub: https://github.com/disler/ten-levels-of-jev · Homepage: https://youtu.be/_U-O5lYhJ7Q · Page: https://gitnova.dev/en/r/disler/ten-levels-of-jev ## Useful for - Gate prompt injection in incoming messages with a noul question and a probability threshold - Route agent requests to the right model or intent with a cheap choice call - Add guardrail hooks to a coding agent's bash and write tool calls ## Why it’s here - 34 stars so far today, about 42 expected by the end of the day. - The spike has held for 2 days in a row — not a one-off blip. - The repository is 2 days old and already has 101 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet. - Top new repositories this week: #169. - About 15 forks a day — people are taking the code. ## Star trust Star growth looks organic. Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer. ## Numbers - Forks: 26 - Issues and pull requests: 5 - Watchers: 1 - Average over the last week: 36 per day - Usual pace: too little history (under two weeks) - Stars in the last hour (measured): 2 ## Stars per day, last 3 days (oldest → newest, today is partial) 2026-09-27 … 2026-09-29: 4, 63, 34 ## Spotted in now - Top new repositories this week: #169 ## Similar by description 1. **NandhaKishorM/laya** — 4.1 · Cooling · AI agents · Python · +549 stars today, ≈ 671 by evening Laya is a non-autoregressive decision engine that answers typed questions (choice, score, noul) over any state (text, email, ticket, JSON) in a single forward pass (~35 ms on GPU) with calibrated probabilities. Full card: https://gitnova.dev/en/r/NandhaKishorM/laya.md 2. **ryana/jevify** — 0.0 · Cooling · AI agents · +0 stars today, ≈ 0 by evening A set of prompts for coding agents that helps investigate what TypeSafe's structured decision model Jev could enable in an existing project. Full card: https://gitnova.dev/en/r/ryana/jevify.md 3. **ollaya-dev/ollaya** — 5.5 · Early signal · Language models · Rust · +63 stars today, ≈ 79 by evening A local runtime for decision models: pulls and serves classification and routing models behind a TypeSafe-compatible API. Like Ollama, but for models that return probabilities instead of text.

Installs as a Claude Code plugin or via skills.sh.

Full card: https://gitnova.dev/en/r/y0usaf/pi-jev.md --- Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score. Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast. Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
