# ✨ Tool Calls Schema Generator
A lightweight, static web app for generating valid tool use JSON schemas for **Claude (Anthropic)** and **OpenAI**. Define functions and parameters with advanced validation options, then copy, download, import, or share your configurations.
## Live App
**[Launch the Generator →](https://toolsuse.dev)**
## Features
- **Multi-Format Support**: Generate schemas for both Claude/Anthropic and OpenAI formats
- **Format Selector**: Easily switch between Claude and OpenAI output formats
- **Live JSON Preview**: Real-time visualization of your schema
- **Validation**: Inline validation with helpful error messages
- **Smart Import**: Auto-detects and imports both Claude and OpenAI formats
- **Actions**:
- Copy JSON to clipboard
- Download as `tools.json`
- Import existing JSON schemas (both formats)
- Share via URL (base64-encoded state)
- Reset all
- **Persistence**: Auto-save to localStorage
## How to Use
### Creating a Function
1. Click **"+ Add Function"**
2. Enter a function name (use snake_case: `get_weather`, `search_products`)
3. Add a brief description
4. Click **"+ Add Parameter"** to define inputs
### Defining Parameters
For each parameter, specify:
- **Key**: Parameter name (required)
- **Type**: string, number, integer, boolean, array, or object
- **Description**: What this parameter does
- **Required**: Check if mandatory
Click **"Advanced"** for additional constraints like enum values, min/max, patterns, etc.
### Working with the Schema
- **Format Selection**: Use the dropdown in the preview panel to choose between Claude/Anthropic or OpenAI format
- **Copy**: Click "Copy" to copy the JSON to your clipboard
- **Download**: Save as `tools.json`
- **Import**: Paste an existing tools JSON array (either format) to edit
- **Share**: Generate a shareable URL with your configuration
- **Validation**: Automatic validation with helpful error messages
### Using with Claude (Anthropic)
```python
import anthropic
client = anthropic.Anthropic(api_key="your-api-key")
tools = [
{
"name": "get_weather",
"description": "Get the current weather in a given location",
"input_schema": {
"type": "object",
"properties": {
"location": {
"type": "string",
"description": "The city and country, e.g. Berlin, Germany"
},
"unit": {
"type": "string",
"enum": ["celsius", "fahrenheit"],
"description": "Temperature unit"
}
},
"required": ["location"]
}
}
]
response = client.messages.create(
model="claude-3-5-sonnet-20241022",
max_tokens=1024,
tools=tools,
messages=[{"role": "user", "content": "What's the weather in Berlin?"}]
)
```
### Using with OpenAI
```javascript
import OpenAI from 'openai';
const client = new OpenAI({ apiKey: process.env.OPENAI_API_KEY });
const tools = [
{
"type": "function",
"function": {
"name": "get_current_weather",
"description": "Get the current weather in a given location",
"parameters": {
"type": "object",
"properties": {
"location": {
"type": "string",
"description": "The city and state, e.g. San Francisco, CA"
},
"unit": {
"type": "string",
"enum": ["celsius", "fahrenheit"]
}
},
"required": ["location"]
}
}
}
];
const response = await client.chat.completions.create({
model: "gpt-4",
messages: [{ role: "user", content: "What's the weather in Boston?" }],
tools: tools
});
```
## Sample Schemas
Check the `/samples` directory for example schemas (Claude/Anthropic format):
- `weather.json` - Simple function with enum
- `array.json` - Array parameters with constraints
- `nested-object.json` - Object with nested properties
- `multi-tools.json` - Multiple functions in one schema
All samples use the Claude/Anthropic format. The tool auto-detects format when importing and can export to either format.
## Analytics Setup
This project includes Google Analytics 4 (GA4) integration. To enable analytics tracking:
1. Get your GA4 Measurement ID from Google Analytics
2. Update the ID in `index.html` and `src/analytics.js`
3. See [ANALYTICS_SETUP.md](./ANALYTICS_SETUP.md) for detailed configuration instructions
The implementation tracks user interactions (button clicks, exports, imports, errors) while respecting user privacy with opt-out capabilities.
