Cursor 3.8: Automations get a /automate skill, Slack + GitHub triggers, and computer use

Cursor’s latest changelog entry (labeled 3.8) focuses on Automations — the scheduled and event-driven agent workflows that run on Cursor’s cloud — with new ways to create them, trigger them, and let them act. (https://cursor.com/changelog)

Create automations with the /automate skill

Cursor added an /automate skill that lets you create an automation directly within a local agent session by describing what you want in plain language. (https://cursor.com/changelog)

Instead of switching to the automations UI to wire everything up first, you can stay in your agent conversation and have Cursor set up the schedule, trigger, and instructions for you.

New triggers: Slack emoji + five GitHub events

Cursor 3.8 expands how automations start:

• Slack emoji trigger: react to any Slack message with a designated emoji to kick off an automation. (https://cursor.com/changelog)
• Five new GitHub triggers: issue comments, PR review comments, PR review submissions, review thread updates, and workflow run completions. (https://cursor.com/changelog)

These make it easier to hook automations into the places where review and discussion already happen, rather than running only on a fixed schedule.

Computer use for cloud agents

Automations’ cloud agents can now use their own computers to produce demos or artifacts — for example, generating a recording or a visual deliverable as part of the automation’s output. (https://cursor.com/changelog)

October 23 follow-up: agents can control desktop applications

Cursor's October 23 announcement says Computer Use lets agents click and type across desktop applications, including the iOS Simulator, rather than only in a browser. Cursor says agents can decide when the tool is needed or users can request it by mentioning “Computer Use” in a prompt. The post says to update Cursor to try it but does not specify plan eligibility or additional system requirements. (https://x.com/cursor_ai/status/2113661506634305834)

Quality-of-life: incomplete saves, default PRs, and memory cleanup

Cursor’s changelog also calls out several smaller improvements:

• Save incomplete automations: navigate away to configure MCP authentication without losing your progress. (https://cursor.com/changelog)
• Open PRs by default: automations can open pull requests without you having to specify it explicitly in the UI. (https://cursor.com/changelog)
• Memory file management: delete outdated memory files from the UI or by instructing the agent. (https://cursor.com/changelog)
