What is termaway CLAUDE.md?

Repository instructions for TermAway, a self-hosted app that lets you access a Mac terminal from an iPad through a web connection.

Use them when installing dependencies, starting the server, navigating the iOS, macOS, web, server, or website code, and understanding the WebSocket-based terminal architecture.

They give the coding agent the project’s commands, folder layout, runtime requirements, and main design so it can work in the repository with the right context.

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	$0.03446	$0.03446
Opus 5.5	$0.01378	$0.01378

Security

Grade C, and why

termaway CLAUDE.md scanned grade C with 1 finding 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 21d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Project: TermAway

TermAway is a self-hosted terminal access solution. Your Mac terminal, on your iPad.

Commands

bun install            # Install dependencies (fast)
node server/index.js   # Start the server (http://localhost:3000)
node --watch server/index.js  # Start with auto-reload

Note: node-pty requires Node.js runtime (not bun) due to native bindings.

Architecture

This is a web-based terminal application that provides remote terminal access over WebSocket. It uses node-pty for pseudo-terminal emulation and xterm.js for browser rendering.

Server (Node.js)

server/index.js: Express HTTP server + WebSocket server. Handles client connections, routes WebSocket messages to session manager, and serves static files. Maps each WebSocket connection to a session via wsSessionMap.
server/sessionManager.js: Manages PTY sessions. Each session has:
- A node-pty process spawned with user's default shell ($SHELL -l)
- A scrollback buffer for reconnecting clients
- A set of attached WebSocket clients
- Sessions persist until explicitly killed or the shell exits

tmux persistence (opt-in)

With TERMAWAY_TMUX=1 (the macOS app's "Keep sessions running when the server stops" preference), a session's PTY runs a tmux client instead of the login shell, so the shell belongs to the tmux server and outlives this process. adoptTmuxSessions() reattaches to everything still running at startup.

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.
