Synchronous Execution

# Synchronous Execution

Immediate request-response execution.

## Category
Tool Execution

## Context
Operations that complete quickly.

## Problem
Most tool calls need immediate results to continue the conversation.

## Solution
Synchronous execution:
- **Immediate**: Returns result in same call
- **Bounded time**: Completes within seconds
- **Blocking**: Agent waits for response
- **Complete result**: Full output returned

## Example (Python)
```python
@tool
def get_weather(city: str) -> Weather:
    """Get current weather. Returns immediately."""
    return weather_api.current(city)
```
## Example (TypeScript)
```typescript
const getWeather = tool({
  execute: async ({ city }) => {
    return await weatherApi.current(city);
  }
});
```

## Considerations
- Most tools should be synchronous
- Set reasonable timeouts (e.g., 30 seconds)
- Use async-job pattern for long operations
