# Tool Calls

When Nova answers your questions, it sometimes needs to look things up or take actions in your system. You'll see these as **tool calls** in the chat — they show you exactly what Nova is doing behind the scenes.

## What Tool Calls Look Like

When Nova uses a tool, you'll see a collapsible block that shows:

* **Tool name** — what action it's performing (e.g., "Get Document", "Search Records")
* **Input** — what it's looking for (e.g., searching for a customer by name)
* **Output** — what it found (e.g., the customer record with phone number and address)

Click the block to expand or collapse the details.

## Common Tool Actions

| Tool                | What It Does                                            |
| ------------------- | ------------------------------------------------------- |
| **Get Document**    | Looks up a specific record (customer, invoice, project) |
| **Search Records**  | Finds records matching your criteria                    |
| **Create Document** | Creates a new record in your system                     |
| **Update Document** | Changes an existing record                              |
| **Run Report**      | Pulls report data for you                               |

## If Something Goes Wrong

If a tool call fails (for example, looking up a customer that doesn't exist), Nova will:

1. Show the error in the tool output (highlighted in red)
2. Try a different approach or ask you for clarification
3. Never leave you hanging — it will always respond with next steps
