<img width="80%" height="80%" alt="image" src="https://github.com/user-attachments/assets/c9b86700-5934-44b6-9210-227495a18d8e" />

gh pr create and gh pr edit now support Copilot Code Review as a reviewer. Request a review with --add-reviewer @copilot, or select Copilot interactively from the searchable reviewer prompt.

Create a pull request and request review from Copilot:

gh pr create --reviewer @copilot

Edit a pull request and request review from Copilot:

gh pr edit --add-reviewer @copilot

Close issues as duplicates with gh issue close --duplicate-of

You can now close issues as duplicates and link to a duplicate issue directly from the CLI. The new --duplicate-of flag accepts an issue number or URL and marks the closed issue as a duplicate of the referenced one. You can also use --reason duplicate to set the close reason without linking a specific issue.

# Close as duplicate, linking to the original issue
gh issue close 123 --duplicate-of 456

# Close with duplicate reason only
gh issue close 123 --reason duplicate

JSON support for gh agent-task

gh agent-task list and gh agent-task view now support --json, --jq, and --template flags, consistent with other gh commands.

gh agent-task list --json id,name,state
gh agent-task view <id> --json state --jq '.state'
