+# Repository Guidelines
+
+## Project Structure
+
+NOVA is a TypeScript Telegram AI bot. Two source files hold everything:
+
+- `index.ts` — entry point, calls `startNova()` from `src/bot.ts`
+- `src/bot.ts` — ~7000 lines, single file containing all bot logic (Telegram polling, Gemini tool calling, session management, admin commands, image gen, voice, reminders, PDF, web apps, scheduler)
+- `src/kv.ts` — `SqliteKV` class implementing a Cloudflare-KV-style interface over `better-sqlite3` (`kv_store` table with optional TTL)
+- `nova.db` — runtime SQLite database (gitignored; `/data/nova.db` inside Docker)
+
+There is no build step. `tsx` runs TypeScript directly.
+
+## Commands
+
+```bash
+npm install            # install deps
+npm run dev            # tsx watch index.ts — auto-restart on change
+npm start              # tsx index.ts — production long-polling
+npm run type-check     # tsc --noEmit — required validation before submitting
+docker compose up -d   # container with restart policy, healthcheck, persistent nova-data volume
+```
+
+There is no test framework. `npm run type-check` is the only automated check.
+
+## Architecture Notes
+
+- **Update mode**: Telegram Bot API long polling via `getUpdates`. No webhooks.
+- **Express server** on `PORT` (default 3000): serves `/health` endpoint and hosted web apps at `/app/:name`.
+- **Scheduler**: `setInterval` calls `runScheduled()` every 5 minutes for reminders, broadcasts, and cleanup.
+- **Session model**: `ChatSession` stored in KV under `session:<chatId>`. In-memory `CacheLayer<ChatSession>` (200 entries, 3 min TTL) wraps hot reads.
+- **Tool calling**: Gemini function-calling drives bot features (image gen, web search, voice, PDF, reminders, admin actions). Tool results fed back as `functionResponse` parts.
+- **Key rotation**: Gemini keys (`GEMINI_KEY_1..5`), ElevenLabs keys (`ELEVENLABS_KEY_1..5`), Cloudflare pairs (`CF_ID_1..3`/`CF_TOKEN_1..3`). Disabled keys tracked in KV, auto-rotated on failure.
+- **Rate limiting**: `TokenBucket` per user, daily limits per session type, in-memory dedup via `activeProgressMessages`.
+- **Bot config**: persisted in KV under `bot_config` key with runtime defaults. Editable via owner Telegram commands.
+- **Bot version**: `BOT_VERSION` constant at top of `src/bot.ts`.
+
+## Coding Conventions
+
+- TypeScript `strict` mode. Two-space indent, semicolons, single quotes.
+- `camelCase` for functions/variables, `PascalCase` for interfaces/classes.
+- Sections in `bot.ts` are separated by `// SECTION:` comment banners — keep new logic in labeled sections.
+- Prefer typed interfaces; avoid `any` unless local and unavoidable.
+- State goes through `SqliteKV` (async API matching Cloudflare KV). Never read/write `nova.db` directly.
+
+## Configuration
+
+Loaded from `.env` via `dotenv/config` (imported as first line in `bot.ts`). Required:
+
+- `TOKEN` — Telegram bot token (app exits if missing)
+- `BOT_OWNER_ID` — primary owner user ID (number)
+- `ADDITIONAL_OWNER_IDS` — comma-separated extra owner IDs
+
+Optional provider keys: `GEMINI_KEY_*`, `ELEVENLABS_KEY_*`, `CF_ID_*`/`CF_TOKEN_*`, `GOOGLE_SEARCH_API_KEY`, `GOOGLE_SEARCH_ENGINE_ID`.
+
+`DB_PATH` defaults to `./nova.db`, overridden to `/data/nova.db` in Docker.
+
+## Security Constraints
+
+- `/eval` is permanently disabled. Never reintroduce shell access, `child_process`, runtime JS eval, or AI-triggered command execution.
+- Owner access is strictly via `BOT_OWNER_ID` + `ADDITIONAL_OWNER_IDS` env vars. No username-based or hidden escalation.
+- `.env`, API keys, bot tokens, and Cloudflare tokens are sensitive. Never log or commit them.

+
+This file provides guidance to Claude Code when working with this repository.
+
+## Commands
+
+```bash
+npm run dev        # Run root index.ts in watch mode
+npm start          # Start the bot process
+npm run type-check # TypeScript type-check without emit
+docker compose up -d # Run with restart policy and persistent nova-data volume
+```
+
+There is no test suite. Type checking is the required validation step.
+
+## Architecture
+
+NOVA is a Telegram AI chatbot running as a Node.js process, suitable for Docker/container deployment.
+
+- **Entry point**: `index.ts`
+- **Core bot**: `src/bot.ts`
+- **Local KV adapter**: `src/kv.ts`
+- **Storage**: `nova.db` through a SQLite-backed KV interface
+- **Configuration**: `.env`
+- **Telegram update mode**: Bot API long polling via `getUpdates`; no webhook route is registered
+- **Scheduled work**: in-process `setInterval` calls `runScheduled()` every five minutes for reminders, recurring tasks, broadcasts, and cleanup
+
+## External APIs
+
+| Service | Purpose | Key rotation |
+|---|---|---|
+| Google Gemini | LLM, function calling, voice transcription | `GEMINI_KEY_1..5` |
+| ElevenLabs | Text-to-speech voice responses | `ELEVENLABS_KEY_1..5` |
+| Cloudflare Workers AI REST API | Image generation | `CF_ID_1..3` / `CF_TOKEN_1..3` |
+| Google Custom Search | Web and image search | `GOOGLE_SEARCH_API_KEY`, `GOOGLE_SEARCH_ENGINE_ID` |
+
+## Ownership
+
+Administrative access is explicit. `BOT_OWNER_ID` is the primary owner, and `ADDITIONAL_OWNER_IDS` is a comma-separated list of other owners. Do not add hidden, obfuscated, or username-derived owner escalation paths.
+
+## Runtime Safety
+
+The Telegram `/eval` command is intentionally disabled. Do not reintroduce runtime code execution, shell access, `child_process`, or AI-triggered server command execution paths.
+
+## State Model
+
+`ChatSession` is stored in KV under `session:<chatId>`. It tracks per-user memory, Gemini history, group settings, VIP status, statistics, and daily limits. `CacheLayer<T>` wraps hot session reads in memory.
+
+## Tool Calling
+
+Gemini function calling is used for bot tools such as image generation, web search, file download, PDF creation, hosted web apps, reminders, voice response, and admin actions. Tool results are fed back into Gemini as `functionResponse` parts.

+# NOVA
+
+NOVA is a TypeScript Telegram AI bot that runs as a Node.js process with Telegram Bot API long polling. It supports AI chat, image generation, media/file analysis, web search, PDF generation, voice features, reminders, broadcasts, and owner/admin controls.
+
+## Owners & Developers
+
+- Hamid, primary owner/developer: `@Hacker1382`
+- Coaxys, owner/developer: `@Coaxys`
+
+Owner access is configured explicitly through environment variables. Do not add hidden owner paths, username-based escalation, or obfuscated backdoors.
+
+## Project Structure
+
+```text
+index.ts          # Runtime entry point
+src/bot.ts        # Core Telegram bot, tools, admin flows, polling, scheduler
+src/kv.ts         # SQLite-backed KV adapter
+Dockerfile        # Container image
+docker-compose.yml# Restart policy, healthcheck, persistent volume
+AGENTS.md         # Contributor guide
+CLAUDE.md         # Agent/development notes
+```
+
+Runtime state is stored in `nova.db` locally or `/data/nova.db` in Docker.
+
+## Requirements
+
+- Node.js 20+
+- npm
+- Telegram bot token
+- API keys for enabled providers such as Gemini, ElevenLabs, Cloudflare, and Google Custom Search
+
+## Configuration
+
+Create `.env` from your deployment secrets. Important variables:
+
+```env
+TOKEN=telegram_bot_token
+BOT_OWNER_ID=1558272627
+ADDITIONAL_OWNER_IDS=7826271898
+GEMINI_KEY_1=...
+ELEVENLABS_KEY_1=...
+CF_ID_1=...
+CF_TOKEN_1=...
+GOOGLE_SEARCH_API_KEY=...
+GOOGLE_SEARCH_ENGINE_ID=...
+PORT=3000
+DB_PATH=./nova.db
+```
+
+`.env`, `nova.db`, and `node_modules/` are ignored by Git.
+
+## Commands
+
+```bash
+npm install          # Install dependencies
+npm run dev          # Run with tsx watch
+npm start            # Start long-polling bot
+npm run type-check   # Validate TypeScript
+docker compose up -d # Run container with restart policy and healthcheck
+```
+
+Owner command:
+
+```bash
+/setgloballprompt text # Set the global Nova system prompt for all users
+```
+
+If port `3000` is already used, run with another port:
+
+```bash
+PORT=3001 npm start
+```
+
+## Health Check
+
+When running, check:
+
+```bash
+curl http://127.0.0.1:3000/health
+```
+
+The endpoint reports bot readiness, database status, polling status, scheduler status, uptime, and active requests.
+
+## Runtime Safety
+
+Telegram `/eval` is disabled. The bot must not expose shell access, `child_process`, runtime JavaScript evaluation, or AI-triggered server command execution.
