{/* MANUAL-CONTENT-START:intro */}
[Linear](https://linear.app) is a modern project management and issue tracking platform that helps teams plan, track, and manage their work with a streamlined interface. Linear supports agile methodologies with customizable workflows, cycles, and project milestones.

With the Linear integration in Sim, you can:

- **Manage issues**: Create, read, update, search, archive, unarchive, and delete issues
- **Manage labels**: Add or remove labels from issues, and create, update, or archive labels
- **Comment on issues**: Create, update, delete, and list comments on issues
- **Manage projects**: List, get, create, update, archive, and delete projects with milestones, labels, and statuses
- **Track cycles**: List, get, and create cycles, and retrieve the active cycle
- **Handle attachments**: Create, list, update, and delete attachments on issues
- **Manage issue relations**: Create, list, and delete relationships between issues
- **Access team data**: List users, teams, workflow states, notifications, and favorites
- **Manage customers**: Create, update, delete, list, and merge customers with statuses, tiers, and requests

In Sim, the Linear integration enables your agents to interact with your project management workflow as part of automated processes. Agents can create issues from external triggers, update statuses, manage projects and cycles, and synchronize data—enabling intelligent project management automation at scale.
