Determining the PR(s)

When this skill is invoked, the PR(s) to update may be specified explicitly, but in the common case, the PR(s) to update will be inferred from the branch / commit that the user is currently working on. For ordinary Git usage (i.e., not Sapling as discussed below), you may have to use a combination of git branch and gh pr view <branch> --repo openai/codex --json number --jq '.number' to determine the PR associated with the current branch / commit.

PR Body Contents

When invoked, use gh to edit the pull request body and title to reflect the contents of the specified PR. Make sure to check the existing pull request body to see if there is key information that should be preserved. For example, NEVER remove an image in the existing pull request body, as the author may have no way to recover it if you remove it.

It is critically important to explain why the change is being made. If the current conversation in which this skill is invoked has discussed the motivation, be sure to capture this in the pull request body.

The body should also explain what changed, but this should appear after the why.

Limit discussion to the net change of the commit. It is generally frowned upon to discuss changes that were attempted but later undone in the course of the development of the pull request. When rewriting the pull request body, you may need to eliminate details such as these when they are no longer appropriate / of interest to future readers.

Avoid references to absolute paths on my local disk. When talking about a path that is within the repository, simply use the repo-relative path.

It is generally helpful to discuss how the change was verified. That said, it is unnecessary to mention things that CI checks automatically, e.g., do not include "ran just fmt" as part of the test plan. Though identifying the new tests that were purposely introduced to verify the new behavior introduced by the pull request is often appropriate.

Make use of Markdown to format the pull request professionally. Ensure "code things" appear in single backticks when referenced inline. Fenced code blocks are useful when referencing code or showing a shell transcript. Also, make use of GitHub permalinks when citing existing pieces of code that are relevant to the change.
