# Put an Idea into Code (PR Author)

> Use the PR Author Expert to have an agent build a PR from a task description — creating the branch, implementing changes, and handling follow-up.

## PR Author

Install **PR Author (GitHub)** from the **Pick Experts** step at onboarding. Then hand it a task description in a session. It cuts the branch, writes the code, opens the PR, and sticks around to deal with CI failures and review comments until the thing merges.

* **Best for**: any change where you'd rather not be the one babysitting CI and rebase conflicts.
* **How to use**: Start a session with the PR Author Expert and describe the task you want implemented. The agent creates a PR, implements the changes, and monitors it in the background — responding to comments, fixing failures, and keeping the PR up to date. To hand off an existing PR, reference its URL, repo + PR number, or `PR #123` instead of describing a task.
