# Create Agent

> Create a structured agent source file. Put Veryfront tools in tool_ids, including project-local tools, built-ins like web_search, and third-party integration catalog tools returned by get_integration such as harvest__list_time_entries. Use provider_tool_ids only for provider-native model tools. Pass avatar_url from create_agent_avatar when an avatar was generated with assign:false.

Create a structured agent source file. Put Veryfront tools in tool\_ids, including project-local tools, built-ins like web\_search, and third-party integration catalog tools returned by get\_integration such as harvest\_\_list\_time\_entries. Use provider\_tool\_ids only for provider-native model tools. Pass avatar\_url from create\_agent\_avatar when an avatar was generated with assign:false.
