+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Commands
+
+```bash
+pnpm dev      # Run with hot-reload (development)
+pnpm start    # Run production
+pnpm lint     # ESLint check (npx eslint src/)
+```
+
+## Architecture
+
+Discord-to-Telegram message forwarder. Tracks messages from users with specific roles on Discord servers and forwards them to Telegram topics.
+
+```
+src/
+├── index.ts              # Entry point, initializes clients
+├── env.ts                # Environment variables (DISCORD_TOKEN, TELEGRAM_BOT_TOKEN)
+├── config.ts             # Loads config.json, validates server/role structure
+├── types.ts              # Shared TypeScript interfaces
+├── discord/
+│   ├── client.ts         # discord.js-selfbot-v13 client
+│   └── handlers.ts       # messageCreate handler, role priority filtering
+└── telegram/
+    ├── client.ts         # wrappergram client
+    └── sender.ts         # Message forwarding, media group handling
+```
+
+**Flow**: Discord messageCreate → filter by guild + role → find highest priority role → forward to Telegram topic with attachments
+
+**Role Priority**: Users with multiple tracked roles → message goes to first matching role's topic (config array order = priority)
+
+## Config
+
+- `config.json` - Server/role/topic mappings (see `config.json.example`)
+- `.env` - Tokens (see `.env.example`)
+
+## Code Style
+
+- ESM with `.js` extensions in imports
+- Node globals via explicit imports (`import process from 'node:process'`)
+- @antfu/eslint-config with 2-space indent, single quotes
