AppitStudio 发布 awesome-jev：Jev 应用与开发者资源社区目录

Discover Jev-powered apps, developer resources, and runnable decision examples.

Jev is TypeSafe AI's System One model: give it state and typed questions, then use the returned choices, scores, and probabilities in your code. This independent community directory collects applications that use Jev, resources for developers, and small, inspectable workflows to learn from.

Explore Jev with our skill

Use Awesome Jev Guide to understand Jev and explore solutions that fit your needs. Describe your workflow in plain language, and your coding agent will help you choose an example, adapt a project, or build a suitable starter—with guided setup along the way.

1. Install the skill. With Node.js 22+ installed, run this in your project directory:

npx skills add AppitStudio/awesome-jev --skill awesome-jev-guide

Select your coding agent when prompted. For Codex, you can add --agent codex. No TypeSafe account or API key is needed to explore ideas or run the offline examples.

2. Open your coding agent in that project and try a prompt.

New to Jev? Start here:

Use awesome-jev-guide. Explain Jev simply, help me understand what I can
build with it, and walk me through the easiest example. I don't have
an API key yet.

Have a workflow in mind? Fill in the brackets:

Use awesome-jev-guide. Today I [describe the work I do manually].
I want to [describe the result]. I use [language, framework, or tools].
Help me find the best starting point in this repo and explain what
needs adapting. Ask me anything essential that's missing.

Ready to build?

Use awesome-jev-guide to build a small starter for [my workflow] using
[my stack]. Start with a working offline demo, explain what I should
customize, then guide me through API-key setup and a first live check
when I'm ready.

3. Follow the next step together. The guide uses current TypeSafe documentation and explains what already works, what needs building, and how to handle uncertain results. When you want live access, it walks you through private key setup—never paste a key into chat.

See the full onboarding guide for installation options, demos, and setup details.

Start here

Explore what you can build — choose a real implementation by the result you want, then follow its guide, worked example, and setup path.

Introduction - Understand Jev's state-and-questions interface and its three decision primitives.
Official quick start - Make a first request using Python or HTTP.
Run an example locally - Try a complete workflow with synthetic mock responses, without an account, an API key, or package installation.
Choose a decision pattern - Match a task to Choice, Score, or Noul and define what happens when the result is uncertain.
HTTP API reference - Check the wire format, authentication, answer fields, and error responses.

Official SDKs and tools

These resources are maintained by TypeSafe.

Agent skill - Official docs for giving a coding agent API context and guidance when designing narrow System One / Jev decision questions (Claude Code plugin and skills.sh install paths).
JavaScript SDK - JavaScript and TypeScript client that infers answer types from the supplied questions.
Python SDK - Synchronous and asynchronous clients with typed answers and configurable retries.
System One Adapter - Run a similar typed-question interface against other LLM providers for comparisons; those responses do not come from Jev.
TypeSafe Agent Skills - Official Claude Code / skills.sh agent skill for designing typed System One / Jev decisions; docs.

Community projects

The community knowledge base turns credited articles into original implementation guides with source links, project connections and stated validation limits.

Browse the project directory for separate app and tool directories, each with full project pages covering use cases, setup, examples, limitations, and review evidence. The links below still take you directly to the upstream projects.

Checks are tied to reviewed versions; see each page and the validation scope. Mocked tests and reported live smoke checks do not establish model quality on your workload.

invalidate - Semantic TTL for agent memory: TypeSafe Jev checks every stored fact against new evidence; code marks superseded memories without rewriting text. Project guide.
IronBee Express - Goal-driven browser agent: each step is one TypeSafe Jev decision over the page's offered controls plus one IronBee DevTools call that acts and returns the next snapshot, so model output never becomes a selector, coordinate or script; after the run it reviews the final page and API responses (and backend traces with IronBee), and runs can be recorded and replayed without the engine. Project guide.
IronBee Gamer - Plays browser games live (2D canvas, Phaser, PixiJS, Cocos, HTML): a perception adapter turns what the page draws into a small JSON state and a decision engine picks every input — hosted TypeSafe Jev with your key, or Laya fine-tuned per game and run locally — with a web UI showing each state, action and probability, a coding-agent trainer for new games, and a shared Hugging Face library.

Project guide.
jeff (Viperwow) - Single-binary Rust classifier server with an admin page: one /v1/systemone-shaped API in front of Jev-compatible models — TypeSafe Jev in the cloud, a local Contrastive-LM (CLM) it installs, or Laya/PipeLLM/any compatible server — with access keys and a playground. Project guide.

jev Claude Code plugin (yinjs) - Claude Code plugin that hands small frequent decisions to Jev at six points — permission requests, prompt-injection warnings on fetched content, a 'done' re-check, prompt nudges, and jev-route effort/model routing — each one ~1 s call that changes nothing when Jev is unsure; Jev via OpenRouter (default), TypeSafe or Vercel AI Gateway. Project guide.
Jev Engineering Cookbook - Curriculum of Jupyter notebook recipes for building with Jev one bounded decision at a time — state in, typed choice / noul / score questions out — with offline fixture runs that need no API key, a live mode, and explicit provenance rules separating synthetic pipeline checks from measured Jev results. Project guide.
Jev Filter (Apixly) - Semantic filtering for AI agent tools: npm package @apixly/jev-filter (CLI, Python library, MCP server) turns large tool outputs, retrieved records, code and logs into compact typed TypeSafe Jev decisions with source IDs, local originals and receipts before they enter an agent's context; batched requests and maintainer-run A/B benchmarks. Project guide.

Jev Highlight Cutter - Codex agent skill and stdlib Python CLI (Chinese docs) that cuts long interviews, podcasts and streams into an evidence-backed highlight reel of a target length: transcript windows are scored by Jev against your preferences, selections are traceable, and FFmpeg makes a local rough cut. Project guide.
Jev Model Router (Codex skill) - Codex skill (Chinese and English docs) where the parent session condenses a non-trivial task and asks TypeSafe Jev to recommend the model tier and reasoning effort for an execution subagent; a standard-library Python script validates the answer against local policy and outputs one JSON decision, keeping the current model on timeout or invalid responses. Project guide.
Jev Moderation - TypeScript and Python SDKs for text moderation with TypeSafe Jev: a bundled, versioned community policy or your own filters, each rule compiled to a Noul question, with review/block thresholds and a policy test CLI (validate, eval, compare with quality gates). Project guide.
Jev Orchestrator - Small Node/TypeScript experiment testing whether Jev can make useful next-step decisions around a coding agent: decision-only by default (inspect the repo, send compact state to Jev via TypeSafe, Vercel or OpenRouter, apply deterministic thresholds, record a JSONL trace), with an explicit --orchestrate mode for a bounded, manually approved loop of safe searches, reads, read-only git, validation scripts and delegation to Codex CLI or Claude Code. Project guide.
jev plays snake - Browser Snake where code computes legal moves and exact facts (food distance, flood-fill reachable cells, dead ends) and TypeSafe Jev picks one move per tick with a single choice question through a small Hono proxy; misses the deadline → the snake goes straight. Project guide.

jev-a2a (Jev router for Paseo agents) - Personal-prototype router that sends work between coding agents running in Paseo sessions on several machines and keeps one record of what was asked, who took it and what came back; when a request names no recipient, TypeSafe Jev chooses the participant. Includes a web board and design docs; published as a worked example, not a product. Project guide.
jev-autopilot - Claude Code plugin that keeps unattended sessions moving: TypeSafe Jev answers Claude's routine questions, screens every non-read-only tool call, and holds risky ones until you tap Proceed or Block on your phone via Telegram; falls back to the terminal when Jev is unreachable. Project guide.
jev-chess (byrencheema) - Experiment where Jev plays chess by choosing one move from all legal moves as a single Choice per turn, with no search or filtering: 350 games vs Stockfish and Maia, 50 vs random, 1,000 Lichess puzzles, Stockfish analysis and all results committed. Project guide.
jev-claude-router (sergeiboikov) - MCP server for Claude Code and Claude Desktop where TypeSafe Jev recommends which Claude model and effort level suit a task, comparing candidates by live OpenRouter prices, context sizes and output limits; it recommends only and never switches the model itself. Distinct from the separately listed jev-claude-router. Project guide.
jev-dev-demo (LIDR) - Spanish-language teaching repo with three runnable demos of 'Jev decides, the LLM reasons': Jira triage that classifies, prioritises and assigns each ticket with a confidence and escalates ambiguous ones, a pre-flight scan that flags existing bugs in the functions a ticket touches, and an LLM router that sends each PR to a large, small or no model (upstream reports 50–75% lower cost); every demo has a --mock mode.

jev-hook-guard - Standard-library Python module and example hook implementing the checks a Claude Code hook should run before sending session text to TypeSafe Jev or another HTTP judge: kill switch, exclusion words with session pins, refusal of secret dumps, masking of keys and personal data, length cut, leftover re-check, pending log line and an https-only, no-redirect POST. Project guide.
jev-imdb-benchmark - Benchmark TypeSafe Jev on IMDB reviews (sentiment/spoilers/quality) with published accuracy, latency, and cost. Project guide.
jev-interceptor - Claude Code UserPromptSubmit hook (repo jev-setup) that asks TypeSafe Jev a few typed questions about every prompt and tells Claude where the work should run — on Claude or an open-model lane (ClinePass via pi, or Codex) — returning the answer as additionalContext; a one-command installer also sets up companion skills, a fast Jev compaction plugin and a spend log, with OpenRouter as a backup path. Project guide.
jev-judge - Pytest/Vitest-style CI evaluations of LLM and RAG outputs: declarative YAML tests (faithfulness, relevance, hallucination, guardrails) answered by TypeSafe Jev noul/score questions instead of an LLM-as-a-judge, with JSON/Markdown reports and an MCP server. Project guide.
jev-judge-rank - Three standard-library Python scripts (and an agent skill) that use TypeSafe Jev to rank a list on several written criteria, merge near-duplicates under one representative, and recall the corpus entries that help with a one-sentence situation; every request and response is logged locally, with a recorded example run and its costs. Project guide.
Jev-Lite - Open System One–style FastAPI decision engine (Qwen backbone) inspired by TypeSafe Jev; independent of hosted Jev. Project guide.
jev-map - Maps each Python function to the tests that run it for coding agents; optional TypeSafe Jev scores candidate links that static analysis misses, checked against real test runs. Project guide.
jev-max - Jev browser agent aimed at pages ordinary Jev agents miss: a piercing snapshot walks open shadow roots and same-origin iframes into one indexed element table, a vision fallback handles canvas, clicks are occlusion-checked, one Jev request per cycle picks the operation and target (TypeSafe or OpenRouter), a small LLM writes text only for fill/select, and an independent Jev check verifies DONE; ships as a Python library, CLI and MCP server. Project guide.
jev-mcp (drmedia) - General-purpose MCP server for System One decision models: MCP clients ask typed yes/no, choice and score questions about structured state and get calibrated probabilities from TypeSafe Jev, OpenRouter (Jev, Cloudflare Clef) or a local server, with batching, retries, image input notes, stdio/HTTP transports and Docker. Distinct from the separately listed jev-mcp. Project guide.
jev-mcp-router (ini8labs) - MCP gateway where TypeSafe Jev answers yes/no per server and tool, so the agent LLM only sees the tools a request needs. Project guide.
jev-mod (VictorGambarini) - Claude Code mod that hands small decisions to a decision model — Jev via TypeSafe, OpenRouter, Venice or OpenCode Zen (or your own server): per-turn routing lanes that set effort and model, the one installed skill a prompt needs, screening of AI-directed instructions after WebFetch / WebSearch / MCP / fetching Bash, and /compact-jev, a summary-free compaction keeping only turns marked keep. Every decision fails open. Distinct from the listed Discord bot Jev-Mod (undeemed). Project guide.
jev-navigator - Python code-navigation library and jvn CLI for agents: a model-free index (definitions, callers, references, imports, git history) plus small typed Jev judgments — check, pick, score — composed into searches like “find the code this sentence describes”. Project guide.

jev-router (Covre81) - Local Anthropic-compatible gateway for Claude Code (or any Messages-API client): on each new human turn TypeSafe Jev answers one ordinal score, sending simple work to a cheap OpenAI-compatible provider (Ollama Cloud free plan by default, Groq or OpenRouter) and structural work byte-for-byte to Anthropic; tool-result turns reuse the route, Jev failures fall back to the primary, and an x-jev-route header plus statusline show each decision. Project guide.
jev-router (Hoppin-Sorter) - Before each prompt, asks TypeSafe Jev what the task is (difficulty, subject, output kind) and which of your skills fits; code then picks the Claude or OpenAI model and optional effort with a quality/cost focus slider. Ships as a Claude Code plugin, a TypeScript/Python router library, a Codex CLI launcher and an optional macOS menu-bar widget. Distinct from the separately listed jev-router. Project guide.
jev-router (KarenCWLin1228) - Small Python CLI that asks TypeSafe Jev which model tier (fast / standard / deep) a coding task needs and returns a recommendation Claude Code, Codex or Antigravity can act on, plus a jev-model-router agent skill wiring it into those hosts. Project guide.
jev-router-mcp - MCP server that routes a question to the best tool via a Jev-compatible /v1/systemone decision engine (works with Laya). Project guide.
jev-search (larguesa) - Complementary semantic search CLI and agent skill: Jev scores whether each candidate line expresses the intent you are looking for, so agents find by meaning what keyword search misses across repo docs, LLM wikis and Obsidian notes; in six simulated tasks lexical + Jev recovered 29 of 34 labeled passages vs 22 for lexical alone (author-reported). Not the listed jev-search app. Project guide.
jev-secret-guard - Claude Code hook: block known secret formats locally; send masked unknowns to TypeSafe Jev so checks never leak the secret. Project guide.

Computer and browser use

Explore computer-use solutions for browser navigation, form filling, data extraction, macOS/Android control, and iOS Simulator experiments. The guide compares inspected implementations, explains their testing boundaries, and develops a practical observe → choose → act → verify design.

Start with Jev Browser (tontoko) for Playwright forms, extraction, and app tests, or Jev Ultrafast to study a compact browser loop. Native macOS and Android have separate implementations; the iOS Jev + AXe work is documented as a public demonstration with an unverified release path.

Try the offline computer-use example to see field selection, exact source extraction, freshness checks, and independent assertions without controlling a real device:

python3 examples/computer-use/run.py

Starter projects

Original examples maintained in this repository. Each includes readable questions, application policy, synthetic responses, tests, and an optional live mode. Mock results demonstrate code behavior, not Jev accuracy.

Computer-use decision cycle - Select a form field and source value, then check a simulated action with independent assertions; uses its own runner.
Quality rubric - Evaluate independent dimensions and combine scores with visible weights in code.
RAG triage - Check a retrieved passage for relevance, evidence, and contradictory information before selecting context.
Span selection - Extract candidate values in code, select one with Jev, and return the exact source value.
Support routing - Select a department and assess explicit urgency, with review paths for uncertain answers.

With Python 3.10 or newer, from a checkout:

python3 examples/run.py support-routing --mock

See the example guide for all commands and live-mode setup. The examples print decisions; they do not execute downstream actions.

Reference project

Start with the runnable tool, then evaluate its policy on your own cases.

Support Router - Route a batch of tickets with configurable departments and review thresholds, inspect each typed answer, and export a human-review queue.
Evaluation runner - Assess routing and abstention on your own labeled development and holdout cases, with bounded live calls and offline replay.

Both tools are maintained here. Start with the synthetic demo; see validation scope for what has been checked.

Patterns and cookbooks

Selected official and community guides, organized by what you want to build. Cookbook results and benchmarks are the authors' reports, not independent measurements by this repository.

Routing and classification

Confidence-gated routing - Add review or fallback paths when a selected answer is uncertain.
Hierarchical classification - Navigate a taxonomy using candidate branches instead of one enormous label set.
Intent routing - Select a handler for a request while keeping routing rules in application code.
Skill suggestion - Shortlist agent skills and separately decide whether any of them is appropriate.
Speculative fan-out - Ask independent questions together and use only the answers relevant to the selected branch.

Retrieval and verification

Classifying RAG passages - Evaluate passage properties before selecting context for an answering model.
Double-checking citations - Judge whether a supplied source supports a claim and flag uncertain decisions for review.
Line-by-line search - Select relevant source lines and separately check whether the document contains an answer.
Milvus reranking notebook - Community cookbook using Gemini embeddings and Milvus retrieval, then Jev Noul relevance scores to reorder the candidate passages in Python.
Milvus search-stopping notebook - Community cookbook using Gemini query generation, Milvus retrieval, and Jev evidence-sufficiency judgments to decide whether a bounded search loop continues.
Re-ranking - Apply semantic judgments to a shortlist produced by an existing retriever.

Extraction and structured data

Composite scoring - Combine separate rubric judgments with application-defined weights.
Date extraction - Select date components, then assemble and validate dates in code.
Knowledge graph entity alignment - Map candidate record pairs to merge, separate, or curator-review outcomes.
Pre-parsed value extraction - Let parsers find possible values and use Jev to select the one matching a semantic request.
Structure recovery - Classify text blocks so code can reconstruct document formatting.

Model behavior and evaluation

Choice self-consistency - Explore uncertain outcomes and the difference between agreement and correctness.
Confidence - Understand how a distribution summary differs from the selected answer and its probability.
Current models - Find model versions, moving aliases, supported inputs, pricing, and current limits.
How to use Jev Score - Walkthrough of the Score primitive: rubrics, probability-weighted calculation, and why score/probabilities/confidence answer different questions (recorded Naruto/Slater example; educational; not a live app).
Jev in the Wild - Study 2,170 public GitHub Jev projects to understand early ecosystem growth, application domains, and decision-use patterns.
Jev 1.13 limitations - Account for literal interpretation, numerical weaknesses, distracting state, and adversarial inputs.
Milvus search-evaluation notebook - Community cookbook using Jev judgments to evaluate search evidence, with synthetic examples and application-owned evaluation calculations.
