Rust CLI for Jev: ask yes/no, choice and rubric questions about text and branch on exit codes, JSON or MCP tools.

Decision plugin for agent harnesses where Jev recommends tools, skills or owners and scores output, for DeepSeek Harness and iPolloWork.

pip-installable Jev kit: a CLI for verify, screen, classify, extract, route and rerank, plus an MCP server for the primitives.

Python library that converts a JSON Schema into Jev questions and returns JSON that validates against the original schema.

Go gateway that pools multiple TypeSafe accounts behind the native System One API with user keys, quotas and failover.

Agent Client Protocol agent that exposes Jev Choice, Score and Noul decisions in IDEs with guided input and probability displays.

jevkit: zero-dependency CLI and eleven MCP tools giving agents typed Jev decisions for routing, triage, guarding, grep, rank and compaction.

Portable Agent Skill teaching coding agents to use Jev as a bounded judgment layer, plus an optional MCP bridge.

Node library providing multi-provider Jev transport with fail-closed validation, used by Jev Browser and Jev MCP.

Independent agent skill that makes a coding agent design, build, test and tune a bounded Jev decision layer with a contract first.

Agent skill that guides you in finding, designing and testing Jev decision loops, including when to keep logic in code.

Python library that finds numeric answers by bisection, asking Jev higher, lower or exactly at each guess.

Browser form for building Jev requests from pasted text without hand-writing JSON, then rerunning to see how steady the answers are.

Small dependency-free CLI and stdio MCP server for Jev's noul, choice and score judgments over text or JSON.

Node/Bun CLI for asking Jev boolean, choice and score questions over text or JSON, with direct or Vercel AI Gateway providers.

Gives Claude Code, Codex, Pi and OpenCode five typed Jev tools (classify, check, score, rank, ask) plus a skill on when to use them.

Codex plugin that consults Jev to choose tools, models and skills, diagnose failed commands and check completion claims.

Local library that turns an image into a transparent text state (OCR, boxes, labels) so Jev can decide over screenshots.

MCP server exposing Jev Noul, Choice and Score via OpenRouter so coding agents can make quick decisions without reasoning tokens.

Swift 6 bridge that runs System One decision models behind Apple's Foundation Models API, on device with Laya or via hosted endpoints.

TypeScript library adding policy, confidence gates, shadow mode, recipes and an eval CLI around Jev answers.

MCP relay that adds use_jev to every server: Jev picks tool calls, the calling model writes free text, the relay executes.

Dependency-free CLI and Codex skill that send local state to Jev for typed judgments and return answers without echoing the state.

MCP server giving coding agents typed judgment tools (verify, screen, rerank, gate, score) backed by Jev, with auto/review/escalate policy.

Portable decision layer for agent harnesses: Jev picks from host-supplied capabilities while the host keeps permissions and execution.

Eval-first MCP server for Jev: prototype questions, map them over many items, and measure accuracy and thresholds on labelled data.

Unofficial, read-only MCP server exposing Jev as four advisory tools: decide, route, risk score and yes/no gate.

MCP server giving any agent Jev's classify, score, yes/no check and allow/confirm/block gating of risky tool calls.

Rust MCP server for Codex that hands classification, relevance, candidate selection and evaluation to Jev with accept/verify policies.

MCP server exposing Jev-style decision models served locally by Ollama's /v1/systemone as classify, yes/no and score tools.
