# Tool Usage Task

You are given a user question and a set of available tools. Call the correct tool(s) to answer the question.

## Question
user: I need to perform health checks on my cluster nodes.
system: Please provide the list of node identifiers you want to perform health checks on.
user: Here are the node identifiers: [{"nodeId": "abcd1234-ef56-gh78-ij90-klmnopqrst12", "tests": ["ping test", "response time"]}, {"nodeId": "abcd1234-ef56-gh78-ij90-klmnopqrst13", "tests": ["ping test", "response time"]}]


## Available Tools

## Instructions

1. Analyze the question and the available tools carefully.
2. Determine which tool(s) to call and with what parameters.
3. Write your answer to `/workspace/output.json` as a JSON array.

## Output Format

Write **only** a JSON array to `/workspace/output.json`. Each element is a single tool call with the function name as the key and its parameters as the value:

```json
[
  {
    "tool_name": {
      "parameter_name": "value"
    }
  }
]
```

For example, to call `search_news` with `query="AI"` and `count=5`:

```json
[{"search_news": {"query": "AI", "count": 5}}]
```

Write **ONLY** the JSON array to `/workspace/output.json`. Do not include explanation or markdown formatting inside the file.

- You should ONLY interact with the environment provided to you AND NEVER ASK FOR HUMAN HELP.
