### SyncHivetraceSDK.output

Source: https://pypi.org/project/hivetrace/1.4.1

Sends an LLM response to the Hivetrace application using the synchronous client.

```APIDOC
## SyncHivetraceSDK.output

### Description
Sends an LLM response to the specified application. Supports optional file attachments.

### Parameters
- **application_id** (str) - Required - The ID of the application.
- **message** (str) - Required - The LLM response message.
- **files** (list) - Optional - A list of tuples containing (filename, file_object, mime_type).
```

--------------------------------

### Trace Tool Invocations

Source: https://pypi.org/project/hivetrace/1.4.1

Decorate functions with @function_tool to enable automatic tracing of tool calls.

```python
from agents import function_tool

@function_tool(description_override="Adds two numbers")
def calculate_sum(a: int, b: int) -> int:
    return a + b
```

--------------------------------

### Hivetrace Output Method Definitions

Source: https://pypi.org/project/hivetrace/1.4.1

Synchronous and asynchronous method signatures for the output function.

```python
# Sync
def output(
    application_id: str,
    message: str,
    additional_parameters: dict | None = None,
    files: list[tuple[str, bytes, str]] | None = None,
) -> dict: ...

# Async
async def output(
    application_id: str,
    message: str,
    additional_parameters: dict | None = None,
    files: list[tuple[str, bytes, str]] | None = None,
) -> dict: ...
```

--------------------------------

### Define Unique Agent IDs

Source: https://pypi.org/project/hivetrace/1.4.1

Assign unique UUIDs to each agent in your configuration file.

```python
PLANNER_ID = "333e4567-e89b-12d3-a456-426614174001"
WRITER_ID = "444e4567-e89b-12d3-a456-426614174002"
EDITOR_ID = "555e4567-e89b-12d3-a456-426614174003"

```

--------------------------------

### Add HiveTrace support to custom tools

Source: https://pypi.org/project/hivetrace/1.4.1

Include an agent_id field in your BaseTool subclass to enable tracking of tool usage by specific agents.

```python
from crewai.tools import BaseTool
from typing import Optional

class WordCountTool(BaseTool):
    name: str = "WordCountTool"
    description: str = "Count words, characters and sentences in text"
    # ADD: HiveTrace field (REQUIRED!)
    agent_id: Optional[str] = None
    
    def _run(self, text: str) -> str:
        word_count = len(text.split())
        return f"Word count: {word_count}"
```

--------------------------------

### Pass HiveTrace client to FastAPI endpoint

Source: https://pypi.org/project/hivetrace/1.4.1

Inject the HiveTrace client from the application state into business logic to enable monitoring.

```python
from fastapi import APIRouter, Body, Request
# ADD: import HiveTrace type
from hivetrace import SyncHivetraceSDK

from src.services.topic_service import process_topic
from src.config import SESSION_ID, USER_ID

router = APIRouter(prefix="/api")

@router.post("/process-topic")
async def api_process_topic(request: Request, request_body: dict = Body(...)):
    # ADD: get HiveTrace client from app state
    hivetrace: SyncHivetraceSDK = request.app.state.hivetrace
    
    return process_topic(
        topic=request_body["topic"],
        hivetrace=hivetrace,  # ← pass client
        user_id=USER_ID,
        session_id=SESSION_ID,
    )
```

--------------------------------

### Define fixed agent UUIDs

Source: https://pypi.org/project/hivetrace/1.4.1

Map agent names to fixed UUIDs to ensure consistent identification in trace logs.

```python
PREDEFINED_AGENT_IDS = {
    "MainHub": "111e1111-e89b-12d3-a456-426614174099",
    "text_agent": "222e2222-e89b-12d3-a456-426614174099",
    "math_agent": "333e3333-e89b-12d3-a456-426614174099",
    "pre_text_agent": "444e4444-e89b-12d3-a456-426614174099",
    "pre_math_agent": "555e5555-e89b-12d3-a456-426614174099",
}
```

--------------------------------

### Close Async Client

Source: https://pypi.org/project/hivetrace/1.4.1

Explicitly closes an asynchronous client instance.

```python
await client.close()
```
