Agent Tools

Inside an app's Build conversation, the agent can search the web, run Python, and generate images. These tools appear in generation progress so you can see how the agent is working.

For MCP and Reflex Agent Skills used by local coding assistants outside the Builder, see Agent Toolkit.

The agent can search the web when a request needs current information, package documentation, or external implementation details. The workspace shows the search queries it uses.

Tell the agent what kind of source or information to prioritize:

Review important facts before shipping. Search results provide context for the build, but they do not replace validation against an authoritative source.

The agent can run Python on demand while building or debugging. It can use the output to:

• Check a script or calculation before adding it to the app.
• Inspect and transform sample data.
• Verify that a package imports successfully.
• Reproduce an error or validate a proposed fix.
• Run tests and other project commands.

Ask for the result you want verified rather than prescribing every command:

Code run during generation is part of the build process. It does not automatically become a user-facing app feature unless the agent adds the corresponding code to the project.

Ask the agent to generate an image when the app needs an original illustration, background, placeholder, or other visual asset. Generated images appear alongside the conversation and app changes.

Describe the intended use, composition, and constraints:

After generation:

1. Review the image at its intended size in Preview.
2. Confirm that text remains legible over it.
3. Check mobile cropping and loading behavior.
4. Ask for a focused revision if the composition or style is wrong.

To provide an existing image as design context instead, see Images and Attachments.

• Do not put passwords, API keys, private tokens, or production credentials in a prompt.
• Use Secrets or an integration form for credentials.
• Do not ask the agent to search for or reproduce private data.
• Review generated assets and third-party information before publishing them.
