Quick Start

This guide gets you from zero to a working agent session.

1. Open a project

Launch Start, click Open Repository, and select any local git repo. Start loads the project and drops you into the main workspace.

2. Talk to the agent

Type in the chat input at the bottom and press Cmd+Enter to send. The agent streams its response in real time.

Try:

What does this project do? Summarize the architecture.

The agent will read your files, analyze the structure, and give you an overview. From here, you can ask it to make changes, fix bugs, or plan new features.

3. Create a task

Open the left sidebar (Cmd+[) and click + in the Tasks section. Give it a title like "Add input validation to the signup form." Tasks land on a Kanban board with three columns: Todo, In Progress, and Done.

The agent can also create tasks during a conversation — just ask it to break down a feature into work items.

4. Switch models

Click the model indicator in the prompt bar to cycle between:

• Opus — Deep reasoning, architecture decisions
• Sonnet — Balanced speed and capability
• Haiku — Quick answers, fast iteration

Pick the model that matches the complexity of what you're asking.

5. Explore the workspace

Start uses a three-panel layout. Toggle sidebars with Cmd+[ (left) and Cmd+] (right).
