Customization

Customization vs Extending

Customization is for changing what already exists in the blueprint — models, prompts, tool configuration, and agent behavior. No new code or plugins required.

Extending is for adding new functionality — new tools, data sources, or integrations that don't exist today. Refer to Extending.
