# Tools and testing

> Real actions, the test panel, and going live

## Tools

A tool is an **action the agent can run during the chat**. They're an **account-wide library**:
created once under **Chat → WhatsApp → Tools**, then attached to whichever agents need them.

<Info>
  **📷 Screenshot needed** — the agent's tools modal, with one attached.

### Types available on WhatsApp

| Type              | What it does                                                                                 |
| ----------------- | -------------------------------------------------------------------------------------------- |
| **API**           | Calls an external service. `{{token}}`s in the URL, params or headers become input variables |
| **Integration**   | Reads and manages a connected system                                                         |
| **Calendar**      | Checks availability and books on the Dialtu calendar                                         |
| **Send template** | Sends an approved Meta template                                                              |
| **End chat**      | Closes the conversation                                                                      |
| **Handoff**       | Passes the chat to a person                                                                  |

<Note>
  **Transfer**, **end call** and **agent swap** are voice-only and don't appear here. The chat
  equivalent of a transfer is **handoff**.
</Note>

### The description is the trigger

**The AI decides when to use a tool by reading its description.** Don't describe what it does;
describe **when it should be used**, and when it shouldn't.

<Warning>
  The **type can't be changed** once the tool is created.
</Warning>

### Integrations

There's currently **one provider available: AgendaPro**.

<Warning>
  **There's no screen for you to connect integrations yourself.** The Dialtu team makes the
  connection. In the builder you'll only see a status indicator — if it says *Not connected*,
  ask your Dialtu contact before going live.
</Warning>

<Note>
  Saving the agent sends the full list of attached tools. If you open the modal and remove one
  by accident, it's detached on save.
</Note>

## Testing

The second tab of the right panel. You type as if you were the customer.

<Info>
  **📷 Screenshot needed** — the Test tab with a conversation and the real-tools warning.

  Save to `/images/en/whatsapp-agents/test-panel.png`
</Info>

<Warning>
  **API, integration and calendar tools run for real.** A calendar tool that writes will **book a
  real appointment**. Use test data.
</Warning>

What is **not** executed for real: ending the chat, opt-out, handoff and template sends render
as terminal cards, because they need a real session.

<Check>**It's free.** The test panel consumes no credits, and unlike the voice one it works **before you save**: it tests the draft on your screen.</Check>

There's an hourly usage limit. You can also **test as a real contact**, to see how it responds
with their memory and history.

## Summary

The third tab. The **Required to create** checklist — name, prompt, number and routing — plus a
recap of the configuration, including the **AI Memory** row.

## Going live

<Warning>
  **Saving publishes immediately.** There's no server-side draft and no version history.
</Warning>

The only control is the **Active / Paused** indicator in the top bar.

<Warning>
  **Pausing an agent doesn't stop its reminders.** The process that sends them doesn't check
  whether the agent is active. To stop it writing entirely, turn reminders off too.
</Warning>

<Tip>
  For big changes to a live agent, **duplicate** it, work on the copy, then swap which one is
  active.
</Tip>

## What doesn't exist

* **Version history** or rollback.
* **Knowledge base** or document upload.
* **Analytics inside the agent** — they're under **Analytics**, filtered by that agent.
* **Bulk actions** on the agent list.
