9remote: Instructions file for Claude Code

CLAUDE.md

9remote CLAUDE.md is an instructions file for Claude Code from decolua/9remote. It costs 1,510 tokens per session, scanned A, original, Apache-2.0.

Project instructions for 9Remote, a system that lets people access a computer's terminal, screen, and files from a phone or web browser. They describe its Node.js host, web app, communication methods, commands, and project layout.

In plain words
What is it for?
Use them when developing, building, or debugging the 9Remote host, web client, documentation site, desktop wrapper, or mobile app.
Why use it?
They give a coding agent the context needed to work safely in a repository with several applications and runtimes. Without them, an agent could run commands in the wrong package or misunderstand how the parts connect.

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

9remote 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 17d 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

9Remote — remote terminal + desktop + file explorer accessible from any phone/browser. Two runtimes talk over a shared transport protocol:

  • host/ — Node.js CLI that runs on the user's machine (the "host"). Serves PTY terminals, WebRTC screen streaming, file explorer. Published to npm as 9remote.
  • web/ — Next.js app (React 19) deployed to Cloudflare Workers via OpenNext. The client UI + signaling/session API backed by Cloudflare D1.
  • The phone/browser (web) connects to the host through a Cloudflare tunnel; web's API only does signaling, auth, and session brokering — the actual terminal/screen data flows host↔client over WS or WebRTC.

npm workspaces: host, web, gitbook (docs site), desktop (Tauri wrapper). expo/ is a separate mobile app (not a workspace).

Commands

Run from repo root unless noted.

npm run dev                # host + web together (run-p)
npm run host:dev           # host only, TUI mode
npm run host:dev:ui        # host only, web-UI mode at localhost:2208
npm run web:dev            # web only (Next dev)

npm run host:build         # sync version + build npm pkg (scripts/buildPkg.js, esbuild + obfuscation)
npm run host:publish       # build + npm publish
npm run web:deploy         # deploy web to Cloudflare Workers

npm run pc:dev             # Tauri dev (host UI + native shell)
npm run pc:build           # build host pkg, then sign + notarize the macOS app

npm run secrets:sync       # push web/.dev.vars secrets to Cloudflare (--env=production|dev)

Host-local scripts (cd host): npm run dev (nodemon TUI), npm run dev:ui (server + Vite UI), npm run build:ui (Vite build of host/ui).

No test runner is configured. ESLint via eslint.config.mjs (next config). Lint: npx eslint ..

Architecture

Transport (the core abstraction)

host/transport/ and web/shared/transport/ are mirror implementations of the same protocol. When you change the wire format, message framing, or codec, change BOTH sides.

  • ProtocolManager.js picks/negotiates a protocol; WsProtocol.js (Socket.IO) and WebRtcProtocol.js (node-datachannel on host, browser RTCPeerConnection on web) are the two transports.
  • codec.js encodes/decodes messages; registry.js maps message types to handlers.
  • Terminal + file explorer default to WS; remote desktop uses WebRTC data channels for low latency.

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.
