Claude Code plugin with nine Jev-judged gates for rules, scope, intent, completion and claims that escalate but never approve.

Safety gate plugin for Claude Code, Codex CLI and Antigravity: local sensitive-file checks, then Jev judges blast radius.

Security hook giving Codex, Copilot, Gemini, Cursor, pi, OpenCode and ACP an auto-mode-like guard via three Jev questions.

Claude Code plugin that moves CLAUDE.md rules into hooks, denying rule-breaking edits and unasked deploys via Jev probabilities.

Deterministic-first 'System 1.5' gate for coding agents: triages test failures, breaks doom loops and governs effort, with optional Jev.

Home Assistant integration that asks Jev, Clef or local Laya about device actions, then applies policy and verifies state separately.

Agent skill where Jev flags 35 AI-writing patterns per paragraph and the model edits only the flagged spots.

OpenBles Firewall 1: open prompt-injection detector for agent inputs, with a Claude Code hook and an optional Jev backend.

Claude Code plugin that runs tap scripts on iOS or Android and has Jev judge each checkpoint's on-screen claims for a pass/fail verdict.

Claude Code kit wiring Jev into a tool-call guard, sub-agent sizing, file search, a browser agent, review, belay and compaction.

Fuzzy linter hook for Claude Code and Codex where Jev checks each written file against team rules and reports violations at edit time.

Natural-language linter combining ast-grep selectors with Jev to catch misleading names, stale comments and tests that miss their claims.

Linter for Obsidian vaults and LLM wikis that flags contradictions, stale claims, unresolved markers and dangling links with Jev.

GitHub Action that reviews repository files against your yes/no questions with Jev and passes only when every answer meets its threshold.

OpenAPI diff tool that adds Jev semantic review of changed prose to deterministic checks, then code decides pass, review or block.

Claude Code mod that answers auto mode's tool-call permission question with eight Jev yes/no checks behind a shell-aware blocklist.

Drop-in proxy for Playwright MCP that adds Jev page triage, prompt-injection masking, snapshot pruning and risky-action gating.

GitHub Action where Jev rates each PR across 19 software-quality dimensions, gates on thresholds and logs to a RawTree dashboard.

Turns AGENTS.md preferences into a Jev-powered semantic linter for diffs, staged files or PRs, feeding findings back to coding agents.

Claude Code plugin that scores a turn's redacted diff on eight Jev risk axes at Stop and asks Claude to reinvestigate once if high.

Java tool that checks whether a sponsored video delivered its brief, with Jev judging subtitle evidence and code gating the result.

Typed-decision accuracy layer for RAG: six checks for intent, relevance, clarification, sufficiency, grounding and caveats.

Configurable GitHub Action where Jev reviews catalog submissions or classifies PRs under a JSON policy and updates one templated comment.

Async Python intent and tool router: Jev picks the handler, and a code-side confidence gate stops weak or invented decisions.

Ring Zero: kernel-level runtime security for AI agents, with Jev as an optional check that can only raise severity, never permit.

Claude Code hook that blocks known key formats locally and sends unknown high-entropy strings to Jev only in masked form.

Reviews agent skills, MCP configs and source with local static checks plus Jev before install, reporting evidence, risk and coverage gaps.
