Built-in Tools

What are Built-in Tools?

When your agent runs in Agent reasoning mode, it has access to a powerful set of built-in tools. These tools let your agent search knowledge, manage files, browse the web, plan complex tasks, and more.

Built-in tools are only available in Agent reasoning mode. Switch your agent’s reasoning mode in Settings → Reasoning.

Available Tools

Knowledge & Research

Your agent can search its training data and capture web pages:

Tool	What it does
Search Knowledge	Searches through your agent’s uploaded documents and training data using AI-powered similarity search
Screenshot	Captures a visual screenshot of any web page — useful for analyzing designs, checking content, or monitoring pages
Web Fetch	Extracts a web page’s text content as structured markdown — useful for reading articles, documentation, or any page content

File Operations

When your agent has access to a Workspace, it can create and manage files:

Tool	What it does
Write	Creates new files or overwrites existing ones
Read	Reads file contents (can target specific line ranges)
Edit	Makes precise, targeted changes to existing files
Search	Finds patterns across all workspace files using regex
Delete	Removes files from the workspace

Planning

For complex tasks, your agent can create structured plans and execute them step by step:

Tool	What it does
Create Plan	Writes a detailed plan document and registers it for tracking
Update Plan	Modifies the plan, advances to the next step, or marks steps complete
Read Plan	Checks the current plan’s status and progress
Accept Plan	Submits a draft plan for your approval before execution begins

Plans always require your approval before the agent starts executing. This gives you a chance to review, modify, or reject the approach.

Communication

Your agent can interact with users and other agents:

Tool	What it does
Ask User	Presents structured questions with selectable options — great for gathering preferences or confirming approaches
Notify User	Sends a proactive notification when something needs attention
Message Agent	Sends a message to another agent in your project for cross-agent collaboration

Code Execution

When your agent has access to a Workspace and Code Sandbox is enabled, it can run code and shell commands:

Tool	What it does
Command	Runs shell commands in an isolated sandbox environment (e.g., `npm install`, `python script.py`, `curl`, `wget`). Has access to all workspace files.

Automation

Your agent can set up tasks that run on a schedule:

Tool	What it does
Schedule Task	Creates a recurring task that runs automatically (e.g., daily reports, weekly checks)

Reasoning

Your agent has an internal thinking tool:

Tool	What it does
Think	Reasons through a problem step-by-step without showing the thinking to the user — helps the agent plan its approach

Tool Approval Levels

Built-in tools have approval levels that control when your agent needs permission or visitor input:

Level	Behavior	Examples
Auto	Executes immediately without asking	Search, Read, Think
Input	Waits for the visitor to respond	Ask User
Conditional	May require approval depending on your settings	Write, Edit, Delete, Command
Always	Always asks for your approval first	Accept Plan, Ask User

Best Practices

Use Agent reasoning mode for tasks that require multiple tools (research + writing, reading + editing)
Let your agent create plans for complex multi-step tasks — review the plan before approving
The Ask User tool is great for gathering requirements before the agent starts working
Use Schedule Task for automated monitoring, reporting, or maintenance workflows
