CLAUDE.md

RNCopilot CLAUDE.md is an instructions file for Claude Code from FouadMagdy01/RNCopilot. It costs 1,635 tokens per session, scanned A, original, MIT.

Technical instructions for RNCopilot, a reusable React Native and Expo mobile-app template. They describe its libraries, project structure, commands, and supported features such as authentication, themes, languages, APIs, and testing.

In plain words
What is it for?
Use them when starting the app, running iOS or Android builds, checking types, linting, formatting, or adding features within the template’s React Native architecture.
Why use it?
They give coding agents the project’s exact technology choices and commands, so new code fits the existing mobile app foundation.

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

RNCopilot 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.

  • Routing: expo-router (file-based, typed routes)
  • Language: TypeScript 5.9
  • Styling: react-native-unistyles 3.x
  • State Management: @tanstack/react-query (server) + Zustand (client)
  • Backend: Supabase (graceful degradation if unconfigured)
  • API Client: Axios with auth/error interceptors
  • i18n: react-i18next (EN/AR, RTL support)
  • Storage: react-native-mmkv
  • Forms: react-hook-form + Zod
  • Linting: ESLint 9 flat config

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.
