agentrium: Instructions file for Claude Code

CLAUDE.md

agentrium CLAUDE.md is an instructions file for Claude Code from talayash/agentrium. It costs 3,852 tokens per session, scanned A, original, MIT.

Instructions for Agentrium, a desktop app for managing several Claude Code command-line sessions in one window. It provides tabs and grid views for running sessions on Windows and macOS.

In plain words
What is it for?
Developing, testing, styling, and packaging Agentrium as Windows installers or macOS applications.
Why use it?
Working with multiple terminal sessions separately makes it harder to monitor and switch between agents. These instructions describe the app’s structure, technologies, and development conventions.

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is talayash/agentrium's own configuration. It tells Claude Code how to work on agentrium itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentrium configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agentrium CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

Agentrium (Agent Desktop Environment) is a cross-platform desktop application (Windows and macOS) for managing multiple Claude Code CLI terminal instances from a unified interface. Built with Tauri 2.x (Rust backend) and React 18 (TypeScript frontend), it provides tabbed and grid views of parallel Claude Code sessions with PTY-based terminal emulation. The release workflow produces NSIS/MSI installers for Windows and .dmg/.app bundles for both Apple Silicon and Intel Macs.

Current version: 1.41.4

Tech Stack

  • Desktop framework: Tauri 2.x
  • Backend: Rust (edition 2021)
  • Frontend: React 18 + TypeScript + Vite
  • Terminal emulation: xterm.js (@xterm/xterm) with fit, search, and web-links addons
  • Styling: Tailwind CSS + Framer Motion. Flat IntelliJ IDEA 2026.1 "New UI"–style design: a 5-step elevation ramp (--elevation-0..4 CSS vars), #3574F0 accent, Inter (UI) + JetBrains Mono (code). Supports dark/light/auto theme, user-set accent color, compact/comfortable/spacious density, UI font scale, and a "reduce motion" toggle that follows the OS prefers-reduced-motion setting until explicitly overridden. Text tokens target WCAG AA contrast. Chrome follows Apple liquid glass ("Concentric Toolbar"): there is no title bar - TitleBar floats as .glass-capsules over the top --h-toolbar of the content cards, window controls live at the top of the sidebar (macOS) or in a caption capsule (Windows), the sidebar and Inspector are .material-lens slabs, and card radius is --radius-window minus --inset-window so corners nest. The content card (terminal, editor) and the status bar stay solid. Tokens and reduced-transparency fallbacks live in src/index.css.
  • State management: Zustand (persisted via zustand/middleware/persist)
  • Database: SQLite via rusqlite (bundled) - stores profiles, workspaces, session history
  • PTY: portable-pty crate for spawning Claude Code processes
  • Notifications: notify-rust crate for native desktop notifications (Windows Toast and macOS NSUserNotification)
  • Auto-updates: tauri-plugin-updater with signed releases from GitHub

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
