Tools and integrations for System One AI models
The layer between your code and the API: SDKs for the languages the vendor does not ship, MCP servers that put the model inside a coding agent, provider packages for the usual frameworks, CLI wrappers and workflow nodes. Most of these are days old and still moving, so check when each one was last touched before you depend on it in something that matters.

- Tool
jkudish/jev-mcp
Proof-of-concept MCP server for Jev that lets Claude Code, Claude Desktop and Codex call the model and receive probabilities they can branch on. The most-starred Jev MCP server found.
- Tool
tamaratran/fast-jev-compaction
Claude Code plugin that replaces the compaction summary with Jev decisions. Every tool call and result is scored in one request against the whole conversation, stale ones are dropped or truncated, and everything kept stays verbatim. Also usable as an npm library.
- Tool
vercel-labs/ai-cli
Vercel Labs CLI for generating from the terminal. Its evaluate command takes a state plus typed questions and defaults its evaluation model to typesafe-ai/jev on the AI Gateway, with -m jev as the shorthand and an --input flag for text or JSON state.
- Tool
Foreman
Places Jev as a fast supervisor above slower Codex coding agents. Codex workers do the engineering while Foreman independently assesses whether the work is complete, requirements are met, tests suffice, or human input is needed.
- Tool
kitze/skillbox
Self-hosted, versioned skills library for AI agents. Serves skills over MCP with scoped clients, and adds optional Jev recommendations for which skill to reach for.
- Tool
typesafe-sdk-js (official TypeScript/JavaScript SDK)
Official TypeScript/JavaScript client published to npm as @typesafe-ai/sdk (v0.6.0), requiring Node.js 20+ and shipping ESM, CommonJS and type declarations.
ChoiceScoreNoul - Tool
NiazMorshed2007/jev-review
Local-first MCP plugin giving Claude Code, Codex, Cursor and OpenCode structured code-quality scores (correctness, complexity, modularity, security) while they work. Sends focused diffs to Jev and keeps keys and code local.
- Tool
system-one-adapter-python (LLM-backed TypeSafeClient drop-in)
Official drop-in replacement for TypeSafeClient that is backed by ordinary LLM APIs, letting developers write System One code before they have Jev access.
ChoiceScoreNoul - Tool
giuliosmall/pg_typesafe
Pre-alpha PostgreSQL extension that calls TypeSafe Jev from SQL for Choice, Noul and Score, including a batched function that classifies many distinct rows in one request.
ChoiceScoreNoul - Tool
jev-router (gargpratyush)
Automatic per-turn model routing for Claude Code and OpenAI Codex. Jev sends simple work to the fast model tier and difficult work to the strong tier while preserving each CLI's native tools, sessions, permissions and authentication.
- Tool
typesafe-sdk-python (official Python SDK)
Official Python client for the TypeSafe System One API, published to PyPI as typesafe-sdk with sync (TypeSafeClient) and async (AsyncTypeSafeClient) clients.
ChoiceScoreNoul - Tool
Jev Browser (vlad-terin)
Agent skill and runtime that uses Jev to select page elements through an agent's existing computer-use browser tools. The agent plans once, then Jev picks elements inside a continuous observe-act-verify loop without an agent turn between steps.
- Tool
Advocaat
Small type-safe client for asking questions about your data, powered by Jev. Returns probabilities, choices and scores in a single request, and ships an agent skill that teaches coding agents how to design the questions.
- Tool
pi-warden
Guardrails for the Pi agent built on pi-typesafe. Jev judges irreversible and off-task tool calls, detects stuck loops, checks unverified completion claims and flags low-quality output, steering the agent rather than interrupting the user.
- Tool
Dicklesworthstone/skillranker
Rust CLI that hands an agent's live session context to Jev, which compares the available skills and estimates which fit the next step. Ships Claude Code hooks, structured JSON, abstention, a terminal display and local feedback.
- Tool
y0usaf/pi-jev
Extension making Jev the decision layer for the Pi coding agent: a measured tool-call gate plus a jev_ask tool. Judges whether an action is destructive, exfiltrates data or exceeds scope, then blocks or warns on calibrated thresholds.
- Tool
itsmostafa/typesafe-mcp
MCP server for TypeSafe shipped as a single static Go binary with no Node or Python runtime. Sends usage guidance to the client so the agent writes better questions.
- Tool
shantanugoel/ask-jev-skill
Hermes skill that lets an agent call jev-latest as a typed tiebreaker, getting Choice, Score and Noul answers with probabilities so it can act or escalate. Documents when to call Jev, confidence gates and pitfalls, and ships a live reliability suite.
ChoiceScoreNoul - Tool
supercorp-ai/supercov
Scores source-file quality by asking Jev a set of yes/no questions, runs the test command you already use, and turns uncovered paths into small queries a coding agent can work through. Scoring costs about a cent per megabyte of source; coverage needs no account, config file or hosted service.
- Tool
0xNatoshi/jev-codex-router
Per-turn model routing for Codex: Jev classifies each turn and picks the model, thinking depth and speed mode, so the cheapest model that can handle a turn serves it. The decision costs about $0.00003 and 0.6 s, and a 7-day replay of 237 real turns measured about 60% savings against a full-frontier baseline.
- Tool
commit-miner
Rust CLI that classifies Git commit diffs and messages with Jev, labelling bug fixes, security fixes with CWEs, and change types. Scans a local repo or remote URL and exports HTML or CSV reports.
- Tool
GhalebDweikat/winnow
A Claude Code hook that splits large tool results into blocks and asks Jev a yes/no relevance question per block, replacing low-relevance blocks with a short recoverable stub before they enter context.
Noul - Tool
yusukebe/hono-jev-router
Experimental Hono router where you describe a request in plain words and Jev decides which description fits the incoming request. The author warns it is not an authorization boundary, and the values of Authorization, Cookie and API key headers are redacted before anything is sent.
- Tool
jkudish/jev-browser
Browser-use tool driving a real headless browser through an MCP server, CLI or library, with Jev choosing the actions. Returns text, markdown, HTML or accessibility-tree output plus traces and screenshots.
- Tool
mrnugget/jev-shell-history
Fish-style autosuggestions for zsh ranked by Jev. As you type, the plugin sends your last 100 distinct history entries and asks which one you are most likely completing, then shows the best match in grey with its score for you to accept.
- Tool
DevMortimer/pi-typesafe
Pi extension that gives the agent and other extensions one key-managed TypeSafe client. A batched typesafe_evaluate tool hands classify, triage, compare and score judgments to Jev in a single call, and a terminal playground runs requests without touching the model's context.
- Tool
gamesonrblx/Jevbridge
ACP and MCP adapter that bridges Jev with any LLM, putting computer use and typed decisions alongside Codex, Claude, Grok and OpenCode.
- Tool
jev-me
Agent skill that runs a /jev-me planning interview. Jev scores which questions would change the plan and whether the user's answers actually settle them, and logs the interview for later inspection.
- Tool
kieranklaassen/ruby_llm-typesafe
TypeSafe structured-output provider for RubyLLM 2, wiring Jev into the RubyLLM provider interface.
- Tool
dannote/jev
Jev for OTP, published on Hex as jev. The model is a peer process: you reply to it from a GenServer and its answer arrives as a message you pattern match on, so clause order becomes the routing and thresholds become guards.
- Tool
jomatsu/pi-jev-auto-mode
Auto mode for the Pi coding agent, which has no permission system of its own. A deterministic layer handles hard denies and your allow and deny patterns, then Jev judges the bash, write and edit calls it escalates and fails closed when it cannot decide. Thresholds come from recorded real-API calibration.
- Tool
compozy/yoshi
Local context-pruning proxy for Claude Code and Codex. Jev judges which conversation history is still needed above a configurable size gate, and Yoshi applies the validated omissions before forwarding to Anthropic or OpenAI; the author calls it a proof of concept headed into CompozyOS.
- Tool
blakestone-x/jev-mcp
Python MCP server exposing Jev as classify, score, check, match and screen tools, with a confidence value on every answer. Ships registration steps for Claude Code, Codex and Cursor that keep the API key out of tool arguments.
- Tool
shiftynick/jev-axi
Agent-ergonomic CLI for Jev with pick, rate, check, rank, triage and guard subcommands, meant for agents offloading snap judgments from the shell.
- Tool
Twister915/typesafe-ai
Rust client for the System One evaluation API with async and blocking backends, Noul, Choice and Score responses deserialised into typed enums, and several judgments batched over one shared state. Retries can be observed step by step and errors stay inspectable.
ChoiceScoreNoul - Tool
AboveColin/HA-Jev
Unofficial Home Assistant integration that asks Jev questions about your house and turns each answer into an entity you can automate on. Questions in configuration.yaml become sensors, and four actions answer inside an automation and return a response variable.
ChoiceScoreNoul - Tool
mejiasd3v/pi-jev-router
Pi extension that lets Jev choose a model and reasoning effort through Vercel AI Gateway, then keeps both pinned for the session. Generation still runs on your existing Pi providers and credentials.
- Tool
reachjalil/jevlogs
Scores OpenTelemetry log records with Jev for diagnostic value, priority and routing, so expensive LLM analysis can be skipped for low-value traces. Every record stays in your archive.
- Tool
saibimajdi/typesafeai-dotnet-sdk
Community .NET SDK for the System One API with typed noul, choice and score questions returning confidence-scored answers. States it is not affiliated with TypeSafe AI.
- Tool
sharziki/semdecide
A Python CLI that turns Jev calls into Unix-pipeline predicates, routing, scoring and JSONL filtering with stable exit codes, plus an agent-safety guard recipe for authorization and destructiveness checks.
- Tool
Ying-Kai-Liao/jev-browser
Browser automation where an LLM plans and Jev decides each tactical action, executed through Playwright without feeding page snapshots to the LLM. README reports 40/42 tasks passing and roughly 5x less token context.
- Tool
devagrawal09/jev-code
Command-line toolkit a coding agent can delegate judgment work to: ranking relevant files, checking a diff against its task and project rules, and triaging test failures or review comments. Each request runs one bounded typed workflow and returns a structured report.
- Tool
Kevthetech143/super-jev
TypeScript harness that connects evidence to Jev judgments, permitted actions and verified outcomes, with pluggable data sources, local JSONL traces and no runtime dependencies. Marked experimental at V0.2.0, with offline demos and mocked API tests passing.
- Tool
ljedrz/nachalnik
Agent runtime in Rust where the context, tools, permissions and requests are explicit state you can read, change and put back, plus an MCP bridge and the kamchatka terminal agent. The linked example uses Jev for content-aware compaction in that agent.
- Tool
TheoOliveira/pi-jev
Adds semantic tool routing, skill discovery and typed Choice, Noul and Score judgments to the Pi coding agent. Opt-in modes pick the model per prompt and use Jev to decide which tool history survives compaction.
- Tool
GodsBoy/jev-agent-skill-router
Routes agent skill selection through typed, confidence-aware Jev questions so a weak match is sent for review instead of guessed. On 72 synthetic requests it routed 68 correctly (94.4%) against 51 (70.8%) for a lexical baseline, at a median 1,287 ms; the author labels the results exploratory.
- Tool
joshmn/typesafe-sdk (Ruby)
Ruby client for typesafe.ai, MIT licensed, requiring Ruby 3.1+. Defaults to jev-latest.
- Tool

ChoiceScoreNoul - Tool
andrelandgraf/typesafe-on-neon
Public HTTP gate running as a Neon Function: Jev inspects the request body, then optionally forwards the same bytes to a caller-chosen HTTPS URL. Endpoints cover prompt injections, unsafe images and unsafe replies, with a companion demo site at safer-with-jev.com.
- Tool
HyunjunJeon/pi-quiet-ask
Decision layer for the Pi coding agent, where Jev answers the closed questions a harness asks dozens of times per session: is this command destructive, did that output leak a key, did the agent verify its claim. Rules live in JSON packs, every answer is recorded, and everything fails open.
- Tool
keeltrace/hermes-jev
An asynchronous Jev integration for Hermes Agent that supervises turn admission, tool-call gating and context curation in the background, using up to sixteen typed choice, score and noul questions per call.
- Tool
baronunread/leanest
A local-first test selector that asks Jev one semantic relevance judgment per test to decide which e2e tests a code change can safely skip, failing open to the full suite on low confidence. Ships a bundled GitHub Action.
- Tool
docxology/daf-jev
Composable Python toolkit for the Jev decision API bundling question builders, confidence gates, an evaluator, calibration tooling, a CLI, an MCP server over stdio and an agent skill.
- Tool
geilt/typesafe-cli
CLI and agent skill for TypeSafe System One exposing typed Choice, Score and Noul judgments from the terminal.
- Tool
abhixhek/jevcal
Fits a per-question confidence threshold to your accuracy target on your own labeled data, checks it on a held-out split, reports how much traffic still needs an LLM, and fails CI when a model update breaks the locked thresholds. Publishes no Jev numbers on purpose.
- Tool
AntonioCoppe/jev-harness
TypeScript library that wraps Jev choice, score and noul answers in the parts production needs: a policy, a confidence gate, shadow mode, reusable recipes and an offline eval CLI. On the same row-filter job it measured 1.3 s against 48.9 s for the Claude Code CLI.
- Tool
doeixd/jev-pref
A CLI that turns AGENTS.md preferences into Jev-checked semantic rules, reviewing code hunks or pull requests with typed choice and noul questions and feeding findings back to a coding agent.
- Tool
FirasSX914/calibre
Measures on your own labelled data where a small model's confidence stops paying off, then routes each decision to Jev or a larger model at the threshold it found rather than a default. On 500 Banking77 examples Jev was 77.8% accurate but 90.7% confident, and threshold 0.67 reached 80.2% accuracy for $0.1033.
- Tool
jamesward/zio-typesafe-ai
Scala 3 and ZIO client for the Jev System One API, typed end to end with no raw JSON. Several questions go out in one round trip as a NamedTuple and come back keyed the same way, and illegal states are unrepresentable: criteria cannot be built out of range and every probability is provably within 0 to 1.
ChoiceScoreNoul - Tool
tumf/jev-cli
Dependency-free Python CLI that sends text, JSON, files or stdin to Jev and returns machine-readable noul, choice or score answers. Several questions go in one request, and output can be reduced to the primary value for shell scripts.
ChoiceScoreNoul - Tool
adarshmishra07/jcm-router
Local proxy between Claude Code and the Anthropic API that picks the model and effort level per message with a Jev decision. The author measured that routing subagents saves money while routing an established main chat loses it: 309 logged requests cost $106.73 against an $87.19 baseline, and $17.12 of the $19.53 loss came from the main chat alone.
- Tool
Butochnikov/laravel-typesafe-jev
Unofficial Laravel 12 and 13 integration on top of the community PHP TypeSafe SDK, adding package discovery, scoped lazy dependency injection, config, a facade and a recording fake. Keeps the SDK's typed DTOs, promises and exceptions.
ScoreNoul - Tool

Independent Rust SDK with async and blocking clients, typed Noul/Choice/Score questions, model discovery, configurable retries and cancellation. Published to crates.io as typesafe-ai-rs.
- Tool
HyunjunJeon/jev-judgment
Agent skill that sends closed coding-agent judgments to Jev and acts on the probabilities. Jev answers yes/no, choice and score questions in about 250 ms, so the agent interrupts the user only when a person must decide, and stops before a command that could destroy data or leak secrets.
- Tool
romaluev/jev-ego
TypeScript browser agent for ego lite with no Chrome, Playwright or browser harness. Each observation produces a numbered element table, and one TypeSafe request picks the operation and the target element. A coding agent can drive the page itself or ask Jev for ranked directions.
- Tool
samtay32/jev-system-architect
Agent skill that hunts for fuzzy semantic judgment in a system and turns it into small Choice, Score and Noul questions, deciding where the Jev boundary belongs, what state each question sees and which ones can run together. Meant to be installed alongside TypeSafe's official skill.
ChoiceScoreNoul - Tool
sufianetaouil/every
Command line search that asks a yes/no question of every function in a codebase and ranks the answers by the probability that the answer is yes. It is grep whose pattern is a question, not embedding search, and the author measured 1,302 functions of gin-gonic/gin in 3.7 seconds for $0.018.
- Tool
AbdelStark/bicameral
Hybrid coding harness for the Pi agent: any LLM writes the code while Jev returns typed probabilities, and deterministic policy code turns those into allow, confirm, block, warn or steer. Isolation stays with containers, so it is not a sandbox.
- Tool
BeLazy167/typesafe-mod
Claude Code mod that routes decisions to Jev: it ranks installed skills against each prompt and answers the agent's own this-or-that questions when confidence is high enough, otherwise falling back to asking the user.
- Tool
Hawxy/TypeSafeAI.Net
.NET SDK for the System One API with dependency-injection support, Microsoft.Extensions.AI integration for chat middleware and guardrails, and native AOT compatibility.
- Tool
AkashPriyadarshii/jev-curate

- Tool
fatwang2/jev-review-action
A configurable GitHub Action that reviews directory submissions and classifies pull requests using only Jev: typed yes/no checks plus one category choice, with code applying the policy and posting one PR comment.
- Tool
hamakyo/jev-starter
A TypeScript toolkit of production patterns around the Jev SDK: decision contracts, confidence-threshold routing with fallback and review paths, an offline evaluation harness, and a RAG diagnosis showcase.
- Tool
noelzappy/tripwire
AI SDK middleware and OpenAI-compatible proxy that judges every LLM response before the user sees it, running seven Jev checks in one call of about 100 ms. Policy is YAML, a high-confidence check blocks while a low-confidence one downgrades to a flag, and the author notes there are no accuracy numbers against real Jev yet.
- Tool
reachjalil/jev-tree
Recursive Choice over a taxonomy. Jev can only list 255 options in one choice question, so jev-tree walks a JSON shape and calls it once per level or partition, letting you select among thousands of leaves.
- Tool
jtsang4/jev-cli
CLI for the Jev evaluation model: typed questions in, structured JSON answers out.
- Tool

- Tool
prismhq/jev-router
Open-source LLM router that uses Jev to pick a model, built on LiteLLM. Clients send a single model ID and Jev routes each request; it falls through without a TypeSafe API key.
- Tool
24601/Augustus
Agent skill for designing judgment-assisted systems with Jev, where code stays in control and the model supplies narrow typed judgments. It maps Choice, Score and Noul onto classical methods such as decision theory, reranking and routing, and requires a falsifying experiment before a design is treated as settled.
ChoiceScoreNoul - Tool
AshutoshVJTI/progressgate
Watches recent agent steps for semantic stagnation, meaning different actions that still chase the same contradicted assumption. Jev reads the trajectory and a small deterministic policy returns CONTINUE, WARN, REPLAN or HALT.
- Tool
luxus/ha-conversation-jev
A Home Assistant conversation agent where Jev classifies an utterance and either takes a fast-path light action or hands off to the Grok conversation agent, gated by confidence and yes/no thresholds.
- Tool
mattn/sqlite3-jev
SQLite extension that calls Jev straight from SQL through jev_noul, jev_choice and jev_score, so a whole table can be classified in one query. Written in C, depends only on libcurl, and builds on Linux, macOS and Windows.
ChoiceScoreNoul - Tool

- Tool
legacybridge-tech/pi-typesafe-jev
Pi extension that exposes System One judgments as five tools: a yes/no Noul, a Choice over a fixed set, a Score over ordered levels, a batched evaluate for several questions about one state, and an ask for a question pinned in a local YAML or JSON file. The tools call the API directly with fetch and carry no SDK dependency.
ChoiceScoreNoul - Tool
noplan-inc/limpet
Stop hook that keeps a coding agent from finishing early. You write completion rules in plain language, and every time the agent is about to stop, Jev scores the stop against each rule in 0.7 seconds and sends it back to work if a rule is violated. Works with Claude Code and Codex.
- Tool
AbdelStark/s1-rs
Rust derive layer that turns ordinary enums and structs into Choice, Score and Noul questions and returns compile-time-checked answers. Results carry confidence, so a policy can gate on it before acting.
ChoiceScoreNoul - Tool
