## 1. MiniMax Connection Analysis
### Architecture
```
┌─────────────────────────────────────────────────────────────┐
│ Agent Runtime │
├─────────────────────────────────────────────────────────────┤
│ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │
│ │ Client │───▶│ Connector │───▶│ MiniMax │ │
│ │ Layer │ │ Pool │ │ API │ │
│ └─────────────┘ └─────────────┘ └─────────────┘ │
│ │ │ │
│ ▼ ▼ │
│ ┌─────────────┐ ┌─────────────┐ │
│ │ Request │ │ Connection │ │
│ │ Builder │ │ Health │ │
│ └─────────────┘ └─────────────┘ │
└─────────────────────────────────────────────────────────────┘
```
### Connection Configuration
| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `api_endpoint` | String | `https://api.minimax.chat` | MiniMax API base URL |
| `timeout` | Integer | 30000 | Connection timeout (ms) |
| `max_connections` | Integer | 100 | Connection pool size |
| `keep_alive` | Boolean | true | Connection reuse |
| `retry_count` | Integer | 3 | Max retry attempts |
### Request Flow
1. **Request Building**: Construct API payload with model parameters
2. **Connection Acquisition**: Get connection from pool
3. **Request Execution**: Send HTTP POST to MiniMax API
4. **Response Handling**: Parse JSON response stream
5. **Connection Release**: Return connection to pool
### Error Handling
| Error Type | HTTP Code | Action |
|------------|-----------|--------|
| `ConnectionTimeout` | 408 | Retry with backoff |
| `RateLimitExceeded` | 429 | Wait and retry |
| `ServerError` | 5xx | Retry with backoff |
| `AuthenticationError` | 401 | Fail fast, alert |
| `InvalidRequest` | 400 | Fail fast, log details |

## 2. Output Contracts Analysis
### Contract Schema
```json
{
"output_contract": {
"version": "1.0",
"required_fields": [
"content",
"model",
"usage",
"finish_reason"
],
"optional_fields": [
"tool_calls",
"citations",
"metadata"
],
"validation_rules": {
"content": {
"type": "string",
"min_length": 0,
"max_length": 128000
},
"usage": {
"type": "object",
"fields": ["prompt_tokens", "completion_tokens", "total_tokens"]
},
"finish_reason": {
"type": "enum",
"values": ["stop", "length", "content_filter", "tool_calls"]
}
}
}
}
```
### Validation Pipeline
```
Raw Response → Schema Validation → Type Coercion → Contract Emit
│ │ │ │
▼ ▼ ▼ ▼
Parse JSON Check Required Normalize Types Emit Valid
or Stream Fields Exist to Contract Output
```
### Contract Enforcement Points
| Stage | Validation | Action on Failure |
|-------|------------|-------------------|
| Pre-send | Request schema | Reject before API call |
| Post-receive | Response schema | Retry or fallback |
| Stream chunk | Partial schema | Buffer until complete |
| Final | Full contract | Return or error |

| `max_delay` | 30000ms | Cap |
| `multiplier` | 2.0 | Exponential factor |
| `jitter` | ±10% | Random variation |
### Retryable Errors
