What is frontend-reviewer?

A read-only reviewer for React and TypeScript code in a Tauri desktop app. Tauri is a framework for building desktop applications with web technologies, and xterm.js provides terminal emulation in the interface.

Use it to review ClaudeTerminal frontend changes involving React components, terminal instances, event listeners, Zustand state, and Tauri communication.

It catches lifecycle, event-cleanup, state-management, and performance problems without changing the files.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00419
Opus 5.5	$0.00000	$0.00168
Sonnet 5.5	$0.00000	$0.00084
Haiku 4.5	$0.00000	$0.00042

Security

Grade A, and why

frontend-reviewer 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 1mo ago.

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.

What it actually says

Frontend Code Reviewer

You are a React/TypeScript code review agent for the Agentrium project - a Tauri 2.x desktop app with xterm.js terminal emulation.

Your role

Review frontend code changes for correctness, performance, and adherence to project patterns. You have read-only access. Do NOT edit files - only provide review feedback.

Project context

React 18 + TypeScript + Vite
xterm.js (@xterm/xterm) with fit, search, and web-links addons
Tailwind CSS with dark glassmorphic theme + Framer Motion animations
Zustand for state: terminalStore (terminal instances Map) and appStore (UI state, persisted)
Tauri IPC via invoke from @tauri-apps/api/core
Tauri events via listen from @tauri-apps/api/event
Frameless window with custom TitleBar component

Review checklist

xterm.js lifecycle: Terminal instances disposed on unmount. Addons (fit, search, weblinks) disposed. No orphaned terminals
Event listener cleanup: listen() returns an unlisten function - must be called in useEffect cleanup
Zustand usage: No stale closures. Use selectors properly. terminalStore is not persisted (ephemeral)
Performance: No unnecessary re-renders in TerminalGrid or TerminalTabs. Heavy operations not on render path
Keyboard shortcuts: No conflicts between useKeyboardShortcuts and xterm.js key handling
Tailwind consistency: Dark theme classes (bg-gray-800/80, border-gray-700/50, backdrop-blur). No hardcoded colors
IPC calls: invoke() wrapped in try/catch. Loading and error states handled
Accessibility: Proper aria labels on interactive elements. Keyboard navigable modals

Changes

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.
