Tools & integrations: what an agent can do Guide

Every Praxivara agent has a set of capabilities that decide what it can actually do. The Tools tab is where you see them all in one place: the built-in tools that come with every agent, plus the connected integrations it uses to reach services like Gmail, Slack, or Shopify.

Built-in tools vs. connected integrations

There are two kinds of capabilities, and the difference matters when you're setting an agent up.

Built-in tools

Built-in tools are always available to your agents. They cover the everyday actions an agent needs to get work done, such as emailing you a summary, saving its results, searching the web, working with files, and generating images. Nothing needs to be connected for an agent to use them.

Note: If an agent has no specific tools assigned, it can still use the built-in tools. You don't have to enable them one by one.

Connected integrations

Integrations let an agent work inside an outside service you use — your inbox, your team chat, your store. Because they act on a real account, an integration has to be connected first. Once it is, the agent can use its actions, and the Tools tab shows which account is powering it.

Viewing an agent's tools

To see everything an agent can do:

1. Open the agent from your list of agents.
2. In the left-hand navigation under Configure, select Tools.
3. Review the capabilities, grouped by integration. Built-in tools appear together, and each connected integration shows the account it's using.

This grouped view lets you confirm at a glance what powers your agent — for example, that it has web search or file creation available, and which inbox or workspace an integration is tied to.

Adding a new capability

The simplest way to give an agent a new tool or integration is to ask the AI builder on the Build tab. Describe what you want the agent to be able to do in plain English, and it wires up the right capability for you.

1. Open the agent and go to the Build tab.
2. Tell the builder the new capability, for example: "Let it send WhatsApp messages" or "Give it access to our Shopify store."
3. The builder adds the tool or integration and updates the agent's setup.
4. Return to the Tools tab to confirm the change appears.

If a new capability relies on an integration, you may be prompted to connect that account before the agent can use it.

When an agent can't do something

If an agent skipped a step or couldn't complete a task, a missing tool is a common cause. A few things to check:

• The tool isn't there yet. Open the Build tab and ask the builder to add it.
• An integration is listed but not connected. The agent can't use an integration until its account is connected. Connect it, then try again.
• You expected a built-in tool. Built-in tools are always available, so if the agent still isn't using one, the instructions on the Build tab may need to be clearer about when to use it.

Testing your changes

After adding or adjusting a capability, run a test to confirm the agent behaves the way you expect. If something isn't right, version history lets you review recent changes and roll back. This makes it safe to experiment with new tools without worrying about losing a working setup.

Tip: Some skills bring extra tools with them. If you install a skill through the builder, you may notice new tools appear on the Tools tab automatically — that's the skill granting the agent everything it needs to follow its playbook.
