Create Custom Agents

You can create custom agents in Nebula to handle specific tasks, workflows, or app integrations — built from the Agents page or just by describing what you want in chat.

How to create an agent

From the Agents pageIn Chat

Open Agents from the top header and click Create agent to open the Create Agent wizard, then step through five short pages.

Identity — name the agent (e.g. "PR Reviewer" or "News Monitor"), and optionally add an image and pick a model. The workspace default model is usually right.

Description — write what the agent handles, its personality, and the outcomes you want. For example: "A research assistant that summarizes articles and cites sources."

Tools — pick the toolkits and services it can act on, like Slack, GitHub, or web search. You can change these later.

Access — set who can use it: general workspace access (none, read, or write), specific people, and the device it runs on (Automatic for cloud, or a pinned one). See scoping & access.

Review & create — check the summary, jump back to edit anything, then click Create agent. The new agent appears on your Agents page immediately.

Describe what you need directly in any conversation:

You

Create an agent that monitors my GitHub repositories for new pull requests and summarizes them.

Create agent

Creating GitHub PR Monitor agent with GitHub and web search capabilities.

Nebula

Done! Your GitHub PR Monitor agent is ready. It can watch your repos for new pull requests and generate summaries.

Nebula will create the agent, configure its tools, and connect it to the right apps — walking you through any setup steps needed.

After creating an agent

Your agent lands ready to work — name, description, model, tools, and access all set. Create it in chat and Nebula fills in the tools and instructions from your description; use the wizard and you choose them as you go. Fine-tune any of it later from the agent details panel.

Configuring your agent

After creating an agent, open its details panel to fine-tune model, instructions, goals, tools, accounts, and variables. See Configure & Manage Agents for the complete guide.
