Required fields

FieldNotes
NameShort label — shown in chat and conversation history
TypeAssistant (general-purpose) or Specialist (narrower, task-focused)
StatusActive to enable chat; Disabled to park it
ModelSee Models. Defaults to Claude Sonnet 4.6.
The type influences the default system prompt applied if you leave the prompt empty.

System prompt

Open the System Prompt section to customize behavior. Write in plain English — describe the agent’s role, tone, any rules, and what kind of output you want. If left blank, a sensible default per type is used.
The system prompt is the single biggest lever on agent behavior. Be specific about scope (“only answer support questions about our product X”) and boundaries (“do not send email without explicit user confirmation”).

LLM settings

Advanced settings in the accordion — safe to leave at defaults for most cases:

Saving

Click Save. The agent is created immediately. Tool permissions default to the regular-user baseline — open the new agent’s detail page and visit the Tools tab to adjust. See Tool Permissions.

Default agent

Each organization can have one default agent, marked with a badge in the list. The default agent is what ShingleAI suggests when you haven’t picked another one explicitly. To mark an agent as default, toggle the flag on its detail page.
