jev
Jev picks the tool that fits Claude's next step and Claude gets it as a hint, shown live and measured against a control group. Native to Claude Code: no gateway, no proxy.
Code you can checkTerminal + desktopPaneBandToastBoxButtonText
network, draws
What it does
- Draws a pane, a band above the prompt, toasts
- Adds /jev, /jev-setup
- Watches tool calls and can refuse them
- Hooks classic.Stop, prompt.attachment, prompt.submit, session.start and 3 more
- Calls the network
Good points
- Written in TypeScript
- Has a desktop-specific branch
- Handles errors
Code to start from
A starter ModsCode writes from the drawing it read, and the mod's own lines that draw, where there are any.
Starter (register.tsx)
register.tsx
import type { Register } from 'claude-code'
// Drawn like jev by Matheus Tonelotto (pane, band, toast), as ModsCode read it from the mod's code:
// https://modscode.com/claude-mods/mods/ntkode-jev/
// Written by ModsCode from that reading, not copied from the mod: use it as you like.
// Each value below stands for one the mod works out at run time; put in your own.
export const register: Register = on => {
// the pane: open it with $.ui.open({ id: 'my-pane', title: "Jev" })

Read from the source at commit 35b86b4aa261 on 2026-10-11. The first group decides whether a mod is listed; the rest is for you to weigh. A later commit is not read until the next crawl.

|---|---|
| Entry read | Every module hooks/hooks.json names was read.jev/plugins/jev/hooks/register.tsx |

| For you to weigh before installing | |
| Where it draws | The terminal, the desktop app, both, or nothing (hooks only: a guard or a prompt rewriter), as its code says. Shown, never a reason to leave a mod out.draws in the terminal and the desktop app, the same in both |
| Install line | Whether its repository's own .claude-plugin/marketplace.json lists it, so it installs from that marketplace with the lines on its page.listed in its repository's .claude-plugin/marketplace.json: installs from there |
| Programs on Windows | Whether every program it starts through $.process exists on Windows (tail, date, open, osascript, /usr/… do not).jev/plugins/jev/hooks/register.tsx:1077 chmod (not on Windows) |
| Network | Whether every fetch names its https host in the code.jev/plugins/jev/hooks/register.tsx:324 fetch(a.url) |

This is a reading of the code text, not a security review: it does not run the mod, and it cannot see what a program the mod starts does. The check before installing is yours. How mods are chosen
Install it
Check it yourself before you install it. Mods run unsandboxed, with your permissions, and ModsCode does not vouch for what this code does. Read its code (or run claude plugin validate . in its folder), weigh what it reaches, and install the commit you read.
From its marketplace
Its repository is its marketplace. Add that marketplace (in the terminal with these commands, or in the desktop app's plugin settings) and install the mod from it:
/plugin marketplace add ntkode/notkode-mods/plugin install jev@notkode-mods/reload-pluginsThis installs the marketplace's latest commit, which may not be the one read here (35b86b4aa261). Compare them before you install. /reload-plugins loads it into a session that is already open.
Try the commit ModsCode read
No marketplace needed. In a terminal, clone the repository, check out the commit read, validate the mod, and load it for one session:
git clone https://github.com/ntkode/notkode-modsgit -C notkode-mods checkout 35b86b4aa26164e0ea9dd17263d429fbd15d36a8claude plugin validate notkode-mods/jev/plugins/jevclaude --plugin-dir notkode-mods/jev/plugins/jevThe validate line lists the events the mod hooks and what it asks Claude Code to do, without running it. The last line loads the mod for this session only and writes nothing to your settings. If the author has rewritten history, the commit may no longer exist.
Ask Claude about it
With the ModsCode connector added, Claude can read this mod's code and what it reaches, and build on them. Ask it like this:
Read the ModsCode mod "ntkode-jev" with its code and make me one like itSearch them from Claude: the MCP connector
