---

Nomena (hereinafter the "Application") is a Discord bot that generates creative project ideas by providing AI-powered project names with explanations and custom anime mascot images. The Application leverages Claude AI for intelligent text generation and Google Gemini for custom avatar creation.

## 1. User Documentation

This section is for those interacting with a live instance of the Application.

### 1.1. Overview

Nomena is a Discord bot designed to help generate creative project ideas. When mentioned in Discord, the bot generates fitting project names based on your description and creates a unique anime mascot image to serve as the project's avatar.

### 1.2. Access Requirements

Currently, the Application is configured for single-user access. Users must be authorised by the bot owner to interact with Nomena. If you attempt to use the bot without authorisation, you will receive a message indicating that the bot can only generate project ideas for authorised users.

### 1.3. How to Use

#### Basic Usage

To generate a project idea, mention the bot in a Discord channel followed by your project description:

```
@Nomena <your project description>
```

**Example:**
```
@Nomena A web application for tracking daily water intake and sending reminders
```

#### What You'll Receive

After mentioning the bot, you will receive a response containing:

1. **Project Names**: 1-5 fitting project names generated based on your description
2. **Name Explanations**: Reasoning for why each name was chosen
3. **Project Description**: Your original input, echoed back for reference
4. **Mascot Image**: A full-body anime character image (3:4 aspect ratio, white background) attached as `avatar.png`

The bot will display a typing indicator while processing your request, which typically takes a few seconds.

#### Unique Names

The Application automatically checks against a database of existing project names to ensure that generated names are unique and don't conflict with previously created projects.

#### Image Generation Limitations

In rare cases, image generation may fail due to API limitations or content restrictions. When this occurs, you will still receive the project names and descriptions, with a message indicating that the image could not be generated.

### 1.4. Best Practices

- **Be Descriptive**: Provide clear, detailed descriptions of your project idea for better name suggestions
- **Include Context**: Mention the project's purpose, target audience, or key features
- **One Request at a Time**: Wait for the bot to respond before sending additional requests
- **Respect Rate Limits**: Avoid excessive requests in rapid succession

### 1.5. Example Interactions

**Request:**
```
@Nomena A mobile app for learning Japanese vocabulary through spaced repetition
```

**Response:**
```
Project Name: KanjiFlow, NihongoLoop, or MemoryMichi

Explanations:
- KanjiFlow: Combines "Kanji" (Japanese characters) with "Flow" (smooth progression)
- NihongoLoop: Uses "Nihongo" (Japanese language) with "Loop" (repetition)
- MemoryMichi: Blends "Memory" with "Michi" (path in Japanese)

Project Description: A mobile app for learning Japanese vocabulary through spaced repetition

   ```

3. **Configure environment variables** (see section 2.4)

4. **Build the application:**
   ```bash
   pnpm run build
   ```

### 2.4. Environment Variables

Create a `prod.env` file in the project root with the following variables:

```env
# Required: Anthropic API key for Claude AI
ANTHROPIC_API_KEY=your_anthropic_api_key_here

# Required: Google Gemini API key for image generation
GEMINI_API_KEY=your_gemini_api_key_here

# Required: Discord bot token
DISCORD_TOKEN=your_discord_bot_token_here

# Required: Logger token for Discord Analytics
LOG_TOKEN=your_log_token_here
```

**API Key Acquisition:**
- **Anthropic API Key**: Sign up at https://console.anthropic.com/
- **Gemini API Key**: Obtain from Google AI Studio at https://makersuite.google.com/
- **Discord Bot Token**: Create a bot at https://discord.com/developers/applications
- **Log Token**: Refer to @nhcarrigan/logger documentation

**All environment variables are required.** The Application will throw an error and refuse to start if any are missing.

### 2.5. Discord Bot Configuration

When creating your Discord bot at https://discord.com/developers/applications, ensure the following:

**Required Intents:**
- `Guilds`: Access to guild information
- `Guild Messages`: Receive messages in guilds
- `Message Content`: Read full message content (privileged intent)

**Bot Permissions:**
- Read Messages/View Channels
- Send Messages
- Attach Files
- Read Message History

**Note:** The Message Content intent is a privileged intent and must be enabled in the Discord Developer Portal.

### 2.6. Customization

#### User Access Control

By default, the bot is configured for single-user access. To modify access control, edit `src/index.ts:44`:

```typescript
if (message.author.id !== "YOUR_DISCORD_USER_ID") {
  await message.reply("Sorry, I can only generate project ideas for authorised users.");
  return;
}
```

You can:
- Replace the user ID with your own Discord user ID
- Remove the check entirely to allow all users
- Implement role-based access control
- Add a whitelist of authorised user IDs

#### Bot Mention ID

Update the bot mention ID in `src/index.ts:37` to match your bot's ID:

```typescript
if (!message.mentions.has("YOUR_BOT_ID", {
  ignoreEveryone:    true,
  ignoreRepliedUser: true,
  ignoreRoles:       true,
})) {
  return;
}
```

Find your bot's ID in the Discord Developer Portal.

#### AI Model Configuration

To modify the AI models used:

**Text Generation (src/classes/ai.ts:78):**
```typescript
model: "claude-sonnet-4-5-20250929"  // Change to any available Claude model
```

**Image Generation (src/classes/ai.ts:100):**
```typescript
model: "gemini-2.5-flash-image"  // Change to any available Gemini model
```

**Token Limits (src/classes/ai.ts:71):**
```typescript
max_tokens: 1000  // Adjust based on your needs
```

#### Project Name Uniqueness Check

The bot fetches existing project names from `https://data.nhcarrigan.com/projects.json`. To use your own data source, modify `src/classes/ai.ts:42-43`:

```typescript
const projectRequest = await fetch("YOUR_DATA_SOURCE_URL");
```

Ensure your data source returns an array of objects with a `name` property:
```json
[
  { "name": "ProjectOne" },
  { "name": "ProjectTwo" }
]
```

To disable the uniqueness check entirely, comment out or remove the fetch logic and modify the system prompt accordingly.

#### Image Generation Prompts

Customise the mascot generation prompt in `src/classes/ai.ts:95-97`:

```typescript
systemInstruction: `Your custom prompt here`
```

Adjust the aspect ratio in `src/classes/ai.ts:95`:

```typescript
imageConfig: { aspectRatio: "3:4" }  // Options: "1:1", "16:9", "9:16", etc.
```

### 2.7. Running the Application

**Development Mode:**
```bash
pnpm run build && node prod/index.js
```

**Production Mode (with 1Password integration):**
```bash
pnpm start
```

This runs: `op run --env-file=prod.env -- node prod/index.js`

**Without 1Password:**

If you're not using 1Password for secret management, modify the `start` script in `package.json`:

```json
"start": "node prod/index.js"
```

Then ensure your environment variables are loaded through your preferred method (e.g., dotenv, system environment variables).

### 2.8. Development Workflow

**Code Linting:**
```bash
pnpm run lint
```

Note: The lint script uses `--max-warnings 0`, meaning any warnings will cause the command to fail.

**Build Process:**
```bash
pnpm run build
```

This compiles TypeScript files from `src/` to `prod/`.

**Testing:**
```bash
pnpm test
```

Note: Currently no tests are implemented. This command returns successfully with exit code 0.

### 2.10. Logging and Monitoring

The Application uses @nhcarrigan/logger for logging with Discord Analytics integration. Logs include:

- Bot startup events (debug level)
- Error tracking (when enabled in the logger)
- Custom analytics events (when configured)

To modify logging behaviour, update the logger initialization in `src/index.ts:21`:

```typescript
const logger = new Logger("Nomena", process.env.LOG_TOKEN);
```

### 2.11. Troubleshooting

**Bot doesn't respond:**
- Verify the bot has the Message Content intent enabled
- Check that the bot mention ID in the code matches your bot's ID
- Ensure the bot has permission to read and send messages in the channel

**Environment variable errors:**
- Verify all four required environment variables are set
- Check for typos in variable names
- Ensure the `prod.env` file is in the project root

**Image generation failures:**
- Verify your Gemini API key is valid and has sufficient quota
- Check if the prompt violates content policies
- Review Google AI Studio logs for detailed error messages

**TypeScript compilation errors:**
- Ensure you're using Node.js 18.x or higher
- Delete `node_modules` and `prod` directories, then reinstall: `pnpm install && pnpm run build`

**Permission errors:**
- Verify bot permissions in Discord server settings
- Ensure the bot role has sufficient privileges

### 2.12. Production Deployment

**Recommended Setup:**
- Use a process manager (PM2, systemd, Docker)
- Implement log rotation
- Set up monitoring and alerting
- Use environment-specific configuration files
- Implement graceful shutdown handling
- Consider using a reverse proxy if exposing any HTTP endpoints

**Example PM2 Configuration:**

```json
{
  "apps": [{
    "name": "nomena",
    "script": "prod/index.js",
    "env_file": "prod.env",
    "instances": 1,
    "autorestart": true,
    "watch": false,
    "max_memory_restart": "1G"
  }]
}
```

**Docker Deployment:**

While no Dockerfile is provided, a basic setup would include:
```dockerfile
FROM node:18-alpine
WORKDIR /app
COPY package.json pnpm-lock.yaml ./
RUN npm install -g pnpm && pnpm install --frozen-lockfile
COPY . .
RUN pnpm run build
CMD ["node", "prod/index.js"]
```
