GitHub makes the Copilot cloud agent for Linear generally available.

The July 23 changelog moves issue-tracker-triggered agent work out of preview, and the same day GitHub Mobile gained the ability to fix failing Actions checks via the cloud agent (GitHub Changelog). Together they push agent invocation off the desktop entirely. An agent that starts from a Linear ticket, and a CI failure dispatched from a phone, are the same bet arriving from the platform side. Combine this with the IssueTrojanBench finding above and you should feel a small chill: issue-triggered agents are exactly the attack surface that measured 66.5%.
