Jev for Claude Code, Codex, and Coding Agents

Coding agents make hundreds of small judgment calls per session: which tool output is still relevant, how hard the next turn is, which review finding matters. Those calls are a natural fit for Jev, which answers in well under a second and costs a tiny fraction of a frontier-model call.

The projects here keep the heavy model for writing code and hand the repetitive yes/no and pick-one decisions to Jev. Context compaction and per-turn routing are the most popular patterns so far.

fast-jev-compaction

★ 7.8k▲ 59

tamaratran/fast-jev-compaction

Claude Code plugin that replaces the compaction summary with Jev decisions. Every tool call and result is scored; stale ones are dropped or truncated, and everything kept stays verbatim.

TypeScriptReviewed

Foreman

★ 804▲ 17

thruwire/foreman

Puts Jev as a fast supervisor above slower coding agents such as Codex, starting from a ticket, spec, or bug report.

PythonReviewed

Jev Review

★ 695▲ 4

devagrawal09/jev-review

Staged code-review workflow for JavaScript and TypeScript with a local dashboard. Jev screens correctness, security, reliability, compatibility, and test risk, then scores severity and suggests a reviewer, with no generative model involved.

TypeScriptReviewed

mu

★ 572▲ 20

qybaihe/mu

Coding agent built on pi with a judgement kernel deciding the routine calls. Five languages.

TypeScriptReviewed

JevHarness

★ 554▲ 13

TianyuCodings/JevHarness

Claude Code and Codex skill in which an LLM writes a task-specific harness that turns observations into typed Jev questions, then revises it from rewards and full traces. No licence yet.

Python

perch

★ 358▲ 6

lakeday-org/perch

Semantic linter that reads each method together with its callers and callees before asking about it. Rules are sentences in a YAML file.

JavaScriptReviewed

Keel

★ 355▲ 18

codejunkie99/keel

Rust

0xNatoshi/jev-codex-router

Self-hosted software factory: coding agents in microVMs, changes verified, and the patch and execution evidence kept, with Temporal coordinating the workflow.

Go

bgts-ai-org/bgts-context-engine

Deterministic code-graph context for coding agents on PostgreSQL, Apache AGE and pgvector, over MCP and REST; Jev or a local decider model can optionally re-select the ranked symbols, failing open to the plain ranking.

Python

jev-pruner

★ 166▲ 1

tamaratran/jev-pruner

Claude Code plugin that uses Jev to trim long Bash output before it reaches the model, leaving errors, source code, and structured output untouched.

TypeScriptReviewed

pi-jev

★ 165▲ 2

y0usaf/pi-jev

Jev as a decision layer for the Pi coding agent in three places: a gate that judges bash, write and edit calls before they run, an output judge that reads what a bash call printed, and a tool the model can call directly.

TypeScriptReviewed

Supercov

★ 159▲ 2

supercorp-ai/supercov

Coverage, security and code quality for coding agents. Jev answers twelve quality and twelve security questions about each source file, and the CLI ranks the files so the agent knows what to fix first.

Rust

Jev Code Reviewer

★ 149▲ 1

TypeScriptReviewed

first-pass

PythonReviewed

sieve

★ 111▲ 6

Sev7eEn7/dsh-sieve
