Jev Rust

Rust agent workbench for ongoing work that keeps branch decisions in their own crate and backend notes in the adapter. Its first decision backend is Cloudflare's Clef, borrowing Clef's System One-shaped state and questions request instead of reinventing the interface.

Local OpenAI- and Anthropic-compatible API gateway in Rust that reuses Codex, Grok, Kiro or Vercel AI Gateway logins. It carries Jev through its model catalog and evaluation path, exposing typesafe-ai/jev via POST /v1/evaluations with state and typed questions.

Local code search for coding agents: ripgrep and BM25 shortlist function-level chunks, Jev Noul relevance questions run across parallel requests, and accepted excerpts return to Codex, Claude Code, OpenCode or Pi through MCP or the `oko ask` command.

Rust coding-agent harness (MIT, ~20k stars) whose crates/jcode-base/src/jev.rs is a typed TypeSafe Jev decision transport, used for memory pruning (memory_jev.rs), browser navigation (browser_jev.rs), and voice routing (voice_intent.rs) with separate provider selectors per purpose.

Agent governance integration where Jev judges two Noul checks per tool call (beyond scope, destructive), an admission policy decides which judgments may become evidence, and admitted evidence degrades Trust, Delegation and Authorization in persistent R2R relation state.

Stencil Labs' coding agent embeds TypeSafe Jev for typed checks, routing, and workflow decisions, with measured Jev tokenizer probes in pi-natives.

An Elasticsearch-compatible autoindex search layer that optionally sends top hits to TypeSafe Jev and reorders results by relevance scores.

A local daemon that pulls open decision models and serves them on TypeSafe's /v1/systemone, so a Jev client switches hosts with TYPESAFE_BASE_URL.

Rust docs for typesafe-jev 0.2.0, a blocking client that sends one state and a set of Choice, Score, and Noul questions and prices input tokens at list rate.

A community Rust port of the official Python SDK with the same primitives, wire format, retries, and error semantics, plus derive macros for typed questions and answers.

A CLI that scores code quality by asking Jev yes/no questions about each file, runs your existing test command, and turns uncovered paths into small actionable queries for agents.

A Rust CLI and PyO3 library that streams JSONL and Parquet rows through Jev Noul and Score rubrics, writing clean and rejected records to disk without rewriting content.

A Rust CLI and MCP server that reranks live DuckDuckGo SERPs with Jev and audits SEO/GEO readiness (schema, robots.txt, sitemaps, llms.txt) with a fifty-rule engine, no paid SEO subscriptions, and a local SQLite history.

A CLI that reranks, filters, or extractively compresses JSON retrieval results by asking Jev separate Noul questions, then lets Rust apply the order and thresholds, reading stdin and writing stdout.

A Rust client for the System One API with typed Noul, Choice, and Score results, async and blocking transports, batched questions over one state, and inspectable retry and error details.

An independent Rust client for the System One API targeting parity with the official Python and JavaScript SDKs at 0.6.0, with async and blocking clients, model discovery, and configurable retries.

A Rust CLI that sends terse YAML or JSON question sets to Jev, validates them offline with 13 lint rules before any billed call, and prints parsed answers as JSON.

A Rust CLI and stdio MCP server that grounds repository and crate discovery in live GitHub and crates.io metadata, then lets Jev score candidates so only verified, installable packages are returned.

A community Rust client for Jev's System One API whose environment variables, defaults, retries, identification headers, and error kinds match the official Python and TypeScript SDKs.

A Rust CLI that classifies Git commit diffs and messages with Jev into bug fixes, security fixes with CWEs, and change types, then writes HTML or CSV reports from saved scans.

A single-binary Rust gate that screens staged git diffs for unredacted secrets, prompt-injection attacks, and destructive commands with calibrated Jev probabilities in about 80 ms, invoked as git jev.

A Rust derive layer for typed System One decisions: enums and structs become Choice, Score, and Noul questions with compile-time-checked, confidence-gated answers, plus a scriptable fake client for network-free tests.

A Rust coding-agent harness and TUI that uses Jev to pick a model and effort, route bounded utility work, and decide what context to keep, with code constraining every choice and validating results.

A Rust CLI and MCP client for Forma benefit claims that can use optional Jev Choice questions to select from an account's valid benefit/category pairs, falling back to an LLM when Jev finds no match or is not confident.

A local browser agent that reads social media by driving your signed-in Chrome across Xiaohongshu, TikTok/Douyin, Instagram, and LinkedIn; a companion Jev Social demo lets Jev choose bounded socai CLI operations and produce a source-linked report.

A Rust CLI that ranks agent skills for the next step with a two-stage Jev pass plus lexical prefiltering, with Claude Code hooks, a TUI, abstention, and --why-not explanations.

A local decision ledger for Jev-class models: caches decisions keyed by redacted model, schema, and state, replays them deterministically in CI, and publishes bundles without raw state.
