Building with Agent(0)

Build, debug, and run your bot with Agent(0), the ADK-aware assistant in the Dev Console.

Agent(0) is an ADK-aware assistant built into the Dev Console. It isn’t a generic chat sidebar: it understands the project you’re working in and helps with the real ADK development loop.

Agent(0) can:

Edit your actions and workflows
Run CLI commands
Debug build and runtime errors
Send test messages to your bot
Inspect traces and read logs
Pull in the integrations your project needs

Project capabilities

Agent(0)‘s project capabilities live with your project, in .agent0/capabilities, while its core harness behavior stays part of the ADK. Because these capabilities are part of the repo, you can customize how Agent(0) works in a specific project, and your whole team shares that setup through version control.
