jevmate

A fast decision layer for coding agents. Jev ranks files, picks the tests a change can break, sorts failures and reviews diffs by risk, so Claude reads only what matters and judges only what Jev is unsure of. Also: long output trimmed, com…

Code you can checkTerminal + desktopPaneBandToastBoxButtonText
runs programs, draws

What it does

  • Draws a band above the prompt, a pane, toasts
  • Watches Bash, Read calls and can refuse them
  • Hooks agent.spawn, plugin.register, prompt.submit, session.attach and 6 more
  • Keeps its own state between turns
  • Starts processes

Good points

  • No network calls
  • 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

// Drawn like jevmate by Gaston Gelhorn (pane, band, toast), as ModsCode read it from the mod's code:
// https://modscode.com/claude-mods/mods/gastongelhorn-jevmate/
// 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.

How to build this: Pane (panel), Deny a tool call

What its code calls

runs programsreads filesenv varstool callsrememberssettings hooksships servers

What its code shows

Read from the source at commit 9362f9956ccd 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.

Decides the listing: code you can check
Entry readEvery module hooks/hooks.json names was read.hooks/jevmate.tsx
ParsesEvery file parses as TypeScript or JavaScript.1 files parsed
All its code is in the modEvery import is a file of the mod or the engine's own module; no packages, no require.all its code is in the mod
ReadableNo minified lines, no eval or new Function, no import of a computed path, no encoded blobs.no minified code, no eval, no encoded blobs
Calls in the openNetwork and programs are reached as $.http.fetch and $.process.run in place, never passed around.every call outside goes through $ in the open
For you to weigh before installing
Where it drawsThe 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, with its own branch for the desktop
Install lineWhether 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 WindowsWhether every program it starts through $.process exists on Windows (tail, date, open, osascript, /usr/… do not).runs no program a Windows PC lacks
NetworkWhether every fetch names its https host in the code.no network
ProgramsWhether every program it starts is named in the code and is not a shell, an interpreter or a network tool.hooks/jevmate.tsx:223 a program named at run time
Reads and sendsWhether it both reads something of yours (files, environment variables, the transcript, settings) and reaches outside (the network, an MCP server, another session, telemetry).reads environment variables, files, but reaches nothing outside
Keys in the sourceWhether the source holds what looks like an API key or a private key.no keys in the source
LicenceAn open licence (MIT, Apache-2.0, BSD, ISC, Unlicense, 0BSD, CC0) with its text lets ModsCode show its code; otherwise the code is linked.MIT
Settings hooksHooks declared in hooks/hooks.json or plugin.json beside the module: a command (a shell when it has no args), an HTTP request, an MCP tool or a model prompt at an event. They run outside $.SessionStart: python3 (through a shell); UserPromptSubmit: python3 (through a shell); PreToolUse: python3 (through a shell); PostToolUse: python3 (through a shell); PostToolUse: python3 (through a shell); PostToolUseFailure: python3 (through a shell); Stop: python3 (through a shell); PreCompact: python3 (through a shell)
Servers it shipsMCP servers (a program, or a URL; a headersHelper is a shell command; a .mcpb bundle is unpacked at run time), LSP servers, monitors (a shell command for the whole session) and bin/ (on the PATH of the Bash tool).mcp jev: python3; bin/: jev on the Bash tool's PATH
Skills, commands, agentsWhat its Markdown declares beyond text: allowed-tools granted for the turn, hooks added when a skill is invoked, a command run before Claude reads the skill.skill pr: allowed-tools ["Bash(gh *)", "Bash(jev *)", "Agent", "Read"]; skill review: allowed-tools ["Bash(jev *)", "Bash(git diff *)", "Read"]; skill setup: allowed-tools ["Bash(jev *)"]; skill sift: allowed-tools ["Bash(jev *)", "Read"]; skill stats: allowed-tools ["Bash(jev *)"]; skill stats: runs a command before Claude reads it; skill tests: allowed-tools ["Bash(jev *)", "Bash(git diff *)"]; skill triage: allowed-tools ["Bash(jev *)", "Read", "Write", "Agent"]
Tools and MCPWhether every tool it calls through $.tool.call and $.mcp.call is named in the code, and none is a shell (Bash through the tool runs a shell without $.process).calls no tool, MCP server or command
Asks of the modelCompletions it runs ($.model.complete, fork, classify), subagents it spawns, prompts it submits as you, and the tools, commands and agents it adds.adds command ?
Events it hooksBy what a hook there can do: gates (refuse a tool call, a prompt, a setting, another plugin), shapes (what the model reads: the system prompt, tool descriptions, each request), reads (your input, the events of the settings hooks, every event with *), and the rest.gates: command.run, tool.call (Bash, Read), prompt.submit, tool.check (Bash), plugin.register · shapes: turn.step · also: session.start, session.attach, ui.close, ui.render (AbovePrompt, Pane) (+4) · timers: clock.after
Reads, by nameThe environment variables and files it names, and whether it reads the transcript, settings.json, the prompt box or the mouse selection.env: HOME, PATH, JEV_AUTO_COMPACT_MIN, JEV_AUTO_COMPACT_IDLE; files: a path computed at run time
Writes, by nameThe files and environment variables it names, and whether it changes settings, the prompt box, the clipboard, the conversation (a row the model reads) or another session.env: JEV_GUARD_MOD

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 GastonGelhorn/jevmate
/plugin install jevmate@gastongelhorn
/reload-plugins

This installs the marketplace's latest commit, which may not be the one read here (9362f9956ccd). 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/GastonGelhorn/jevmate
git -C jevmate checkout 9362f9956ccddd0b75878046ad50cd157e57235e
claude plugin validate jevmate
claude --plugin-dir jevmate

The 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 "gastongelhorn-jevmate" with its code and make me one like it

Search them from Claude: the MCP connector
