Tool Calls / Actions

Learn about the tools AI agents use and how they appear in chat.

Agents automatically select and execute the right tools based on your message. Tool execution status is visible in the chat timeline.

Primary Agent Tools

Below are the main tools agents use. These can be extended further by adding skills and MCP apps.

Capability	Description
Document & code search	Search across project documents and source code to understand content
File read & write	Create new documents, read or update existing files
Web search & page reading	Search the internet and retrieve page content
Python execution	Data processing, analysis, script execution, and file generation. Generated files (Excel, CSV, PDF, etc.) can be downloaded directly from chat
Document analysis	Read and analyze uploaded images and PDFs
Context search	Reference learned information from past conversations to improve accuracy

File Download

When the Python execution tool generates files, they are listed in the chat message with a download button and file size. Click the download button to save the file to your device.

Supported file formats include:

• Spreadsheets: xlsx, csv, tsv, xls
• Documents: pdf, docx, doc, pptx, ppt
• Images: png, jpg, jpeg, gif, webp, tiff, bmp
• Data: json, and other formats

Skills

Skills are packages that extend an agent’s specialized capabilities. They bundle tools, instructions, and reference materials, and are activated automatically when needed.

For example, asking “Create a sales report in Excel” triggers the Excel generation skill, which produces a spreadsheet with formulas and formatting.

Notable skills:

• Excel Generation — Create and edit xlsx, csv, tsv files with formulas, formatting, and multiple sheets
• Deep Research — In-depth research and analysis across multiple sources

→ For adding and managing skills, see Skills.

MCP Integration Tools

When MCP apps are connected to an agent, their tools become available alongside the agent’s built-in tools and execute the same way in chat.

For tools that require approval, a confirmation prompt is shown before execution.

→ For connecting MCP apps, see Apps (MCP).

Tools by Agent Type

Different agent types have access to different tools.

Custom agents can extend their tool set by adding skills and MCP apps.
