Custom Tools

What Are Custom Tools?

Custom tools let you extend your agent's capabilities beyond the built-in apps. You can define new tools with custom input schemas and instructions for how the agent should use them.

Building a Custom Tool

In your agent's config panel, look for the Custom Tools section. From there you can define:

• •Tool name — A unique identifier (e.g., "generate_weekly_report").
• •Description — What the tool does, so the AI knows when to use it.
• •Input schema — The parameters the tool accepts (JSON schema format).
• •Instructions — How the tool should behave when called.

Once created, the custom tool appears in your agent's available tools list and can be called during chat conversations just like any built-in tool.
