            Work on GitHub issue: ${{ github.event.issue.html_url }}

            Fetch the issue, analyze what documentation changes are needed, and
            implement them.

            When complete, write .pr-body.md following this structure:

            ## Summary
            One sentence describing what was fixed/added/changed.

            ## Changes
            Bulleted list of specific changes (be concise, focus on what matters).

            ## Upstream coordination needed
            Only include this section if there are issues requiring fixes in upstream
            repos (docker/cli, moby/moby, etc.). Otherwise omit it entirely.

            Fixes #${{ github.event.issue.number }}
