pocket-server: Instructions file for Claude Code

CLAUDE.md

pocket-server CLAUDE.md is an instructions file for Claude Code from yayasoumah/pocket-server. It costs 2,828 tokens per session, scanned A, original, Apache-2.0.

A project guide for Claude Code, an AI coding assistant, describing Pocket Server's purpose, architecture, design principles, and source-code modules. Pocket Server is a Node.js and Hono server for the Pocket Agent mobile app.

In plain words
What is it for?
Use it when developing or reviewing Pocket Server. It helps locate modules and understand features such as real-time WebSocket communication, stored sessions, and background agent coordination.
Why use it?
It gives the coding assistant the context needed to work within the project's structure and conventions. This reduces guesswork when changing the agent, authentication, file-system, or terminal code.

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

pocket-server 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 9d 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.

Project Overview

Pocket Server is a Node.js + Hono WebSocket server that provides AI agent capabilities, file system operations, terminal management, and background agent orchestration. Built with TypeScript and ESM modules, it serves as the backend for the Pocket Agent mobile app.

Architecture

Core Design Principles

  • Event-driven mailbox pattern - Each session has its own AgentRunner with strict ordering
  • Server-authoritative storage - All conversation data persisted to data/sessions/
  • Streaming-first - Optimized for real-time WebSocket streaming with frame aggregation
  • Module isolation - Clean separation between agent, auth, file system, and terminal modules

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.
