Do you need to actively train the agent on each codebase?

TL;DR

No, Autonomy automatically maps and updates its understanding of the codebase.

The agent automatically detects if it is on a codebase it has never seen before and triggers ACE (Agentic Context Engine) to map the codebase for contextual understanding. There is no need for manual intervention. ACE further updates the codebase understanding every time it detects a change in any of the code files.
