Linear
Connect your workspace and a new issue can start an agent that implements it and opens a pull request linked back to the ticket. Inside any session, agents can read, create, and update issues, and @ellipsis on an issue gets an answer in the comments.
One trigger block and a filed issue becomes a running agent. The ticket your team already wrote is the prompt, so nobody translates a description into instructions before the work can begin.
The agent reads the issue, works the problem in its own sandbox, opens a pull request linked back to the ticket, and comments what it did. The issue moves because the agent moved it.
Linear is not just the trigger. Any session on a connected account can read issues and comments, update fields, move statuses, and file new issues, so a nightly audit lands in your backlog instead of a log nobody opens.
