Agents

Build your own specialists on top of Operator's base agents

A user-defined agent is a saved specialist that wraps one of the platform's base agents with your own identity, instructions, greeting, capabilities, and (optionally) a flow diagram. Once saved, it appears in the agent selector and behaves like any built-in agent — except it follows the focus you gave it.

Why build your own agents

User-defined agents are useful when you want a repeatable specialist tuned to the way your business actually works.

Agent or Process

Every user-defined entry has a Kind:

You don't pick the Kind from a menu — the Agent Builder decides at creation time from how you describe what you want, and you can flip the Kind later from the agent's Properties.

What you can shape on an agent

Each of these is its own area you can fill in over time:

Area What it controls
Identity Name, identifier (for @mentions), description, icon
Base agent Which platform agent yours extends — sets available capabilities, reasoning ceiling, and instance requirements
Reasoning level How deeply the agent thinks per turn (Fast → Genius, or Auto)
Instructions Private guidance the AI sees on every turn; users don't see it
Greeting Welcome message and quick-action buttons shown when a new chat starts
Welcome screen A WYSIWYG preview of what the user sees before they type
Capabilities The tools the agent is allowed to use (data, email, calendar, sub-agents, …)
Diagram An AI-generated map of the agent's data flow and actions — see Working with Diagrams
Optimization Per-instance warm-up that pre-resolves the names and IDs the agent uses — see Agent Optimization
Sharing Give colleagues access to use (not edit) the agent
Delegation Let the agent split work across other user-defined agents — see Delegation & Sub-Agents

How you build and edit them

You build agents by talking to the Agent Builder. Open it from the agent selector, describe what you want in plain language, and it creates the agent for you. A live preview panel on the side shows the agent taking shape — instructions, greeting, welcome screen, diagram — and you can keep refining either through the conversation or by editing fields directly in the preview.

There's no separate "form" to fill in upfront. The agent exists from the first creation step; everything after that is iteration.
